elf: Avoid re-initializing already allocated TLS in dlopen (bug 31717)
The old code used l_init_called as an indicator for whether TLS
initialization was complete. However, it is possible that
TLS for an object is initialized, written to, and then dlopen
for this object is called again, and l_init_called is not true at
this point. Previously, this resulted in TLS being initialized
twice, discarding any interim writes (technically introducing a
use-after-free bug even).
This commit introduces an explicit per-object flag, l_tls_in_slotinfo.
It indicates whether _dl_add_to_slotinfo has been called for this
object. This flag is used to avoid double-initialization of TLS.
In update_tls_slotinfo, the first_static_tls micro-optimization
is removed because preserving the initalization flag for subsequent
use by the second loop for static TLS is a bit complicated, and
another per-object flag does not seem to be worth it. Furthermore,
the l_init_called flag is dropped from the second loop (for static
TLS initialization) because l_need_tls_init on its own prevents
double-initialization.
The remaining l_init_called usage in resize_scopes and update_scopes
is just an optimization due to the use of scope_has_map, so it is
not changed in this commit.
The isupper check ensures that libc.so.6 is TLS is not reverted.
Such a revert happens if l_need_tls_init is not cleared in
_dl_allocate_tls_init for the main_thread case, now that
l_init_called is not checked anymore in update_tls_slotinfo
in elf/dl-open.c.

elf: handle addition overflow in _dl_find_object_update_1 [BZ #32245]
The remaining_to_add variable can be 0 if (current_used + count) wraps,
This is caught by GCC 14+ on hppa, which determines from there that
target_seg could be be NULL when remaining_to_add is zero, which in
turns causes a -Wstringop-overflow warning:
In file included from ../include/atomic.h:49,
from dl-find_object.c:20:
In function '_dlfo_update_init_seg',
inlined from '_dl_find_object_update_1' at dl-find_object.c:689:30,
inlined from '_dl_find_object_update' at dl-find_object.c:805:13:
../sysdeps/unix/sysv/linux/hppa/atomic-machine.h:44:4: error: '__atomic_store_4' writing 4 bytes into a region of size 0 overflows the destination [-Werror=stringop-overflow=]

| ^~~~~~~~~~~~~~~~~~~~
In function '_dl_find_object_update':
cc1: note: destination object is likely at address zero
In practice, this is not possible as it represent counts of link maps.
Link maps have sizes larger than 1 byte, so the sum of any two link map
counts will always fit within a size_t without wrapping around.
This patch therefore adds a check on remaining_to_add == 0 and tell GCC
that this can not happen using __builtin_unreachable.
Thanks to Andreas Schwab for the investigation.

2024-02-01 02:17:27 +08:00
|
|
|
|
* The <stdbit.h> header type-generic macros have been changed when using
|
|
|
|
|
|
GCC 14.1 or later to use __builtin_stdc_bit_ceil etc. built-in functions
|
|
|
|
|
|
in order to support unsigned __int128 and/or unsigned _BitInt(N) operands
|
|
|
|
|
|
with arbitrary precisions when supported by the target.

|
2024-02-01 19:02:01 +08:00
|
|
|
|
* The GNU C Library now supports a feature test macro _ISOC23_SOURCE to
|
|
|
|
|
|
enable features from the ISO C23 standard. Only some features from
|
|
|
|
|
|
this standard are supported by the GNU C Library. The older name
|
|
|
|
|
|
_ISOC2X_SOURCE is still supported. Features from C23 are also enabled
|
|
|
|
|
|
by _GNU_SOURCE, or by compiling with the GCC options -std=c23,
|
|
|
|
|
|
-std=gnu23, -std=c2x or -std=gnu2x.
|
|
|
|
|
|
|
2024-05-20 21:41:39 +08:00
|
|
|
|
* The following ISO C23 function families (introduced in TS
|
|
|
|
|
|
18661-4:2015) are now supported in <math.h>. Each family includes
|
|
|
|
|
|
functions for float, double, long double, _FloatN and _FloatNx, and a
|
|
|
|
|
|
type-generic macro in <tgmath.h>.
|
|
|
|
|
|
|
Implement C23 exp2m1, exp10m1
C23 adds various <math.h> function families originally defined in TS
18661-4. Add the exp2m1 and exp10m1 functions (exp2(x)-1 and
exp10(x)-1, like expm1).
As with other such functions, these use type-generic templates that
could be replaced with faster and more accurate type-specific
implementations in future. Test inputs are copied from those for
expm1, plus some additions close to the overflow threshold (copied
from exp2 and exp10) and also some near the underflow threshold.
exp2m1 has the unusual property of having an input (M_MAX_EXP) where
whether the function overflows (under IEEE semantics) depends on the
rounding mode. Although these could reasonably be XFAILed in the
testsuite (as we do in some cases for arguments very close to a
function's overflow threshold when an error of a few ulps in the
implementation can result in the implementation not agreeing with an
ideal one on whether overflow takes place - the testsuite isn't smart
enough to handle this automatically), since these functions aren't
required to be correctly rounding, I made the implementation check for
and handle this case specially.
The Makefile ordering expected by lint-makefiles for the new functions
is a bit peculiar, but I implemented it in this patch so that the test
passes; I don't know why log2 also needed moving in one Makefile
variable setting when it didn't in my previous patches, but the
failure showed a different place was expected for that function as
well.
The powerpc64le IFUNC setup seems not to be as self-contained as one
might hope; it shouldn't be necessary to add IFUNCs for new functions
such as these simply to get them building, but without setting up
IFUNCs for the new functions, there were undefined references to
__GI___expm1f128 (that IFUNC machinery results in no such function
being defined, but doesn't stop include/math.h from doing the
redirection resulting in the exp2m1f128 and exp10m1f128
implementations expecting to call it).
Tested for x86_64 and x86, and with build-many-glibcs.py.

lastlog, struct utmp, struct utmpx (such as i386, powerpc64le, rv32,
|
|
|
|
|
|
rv64, x86-64) switched from a signed to an unsigned type for that
|
|
|
|
|
|
field. This allows these fields to store timestamps beyond the year
|
|
|
|
|
|
2038, until the year 2106. Please note that applications are still
|
|
|
|
|
|
expected to migrate off the interfaces declared in <utmp.h> and
|
|
|
|
|
|
<utmpx.h> (except for login_tty) due to locking and session management
|
|
|
|
|
|
problems.

* __rseq_size now denotes the size of the active rseq area (20 bytes
|
|
|
|
|
|
initially), not the size of struct rseq (32 bytes initially).

linux: statvfs: allocate spare for f_type
This is the only missing part in struct statvfs.
The LSB calls [f]statfs() deprecated, and its weird types are definitely
off-putting. However, its use is required to get f_type.
Instead, allocate one of the six spares to f_type,
copied directly from struct statfs.
This then becomes a small glibc extension to the standard interface
on Linux and the Hurd, instead of two different interfaces, one of which
is quite odd due to being an ABI type, and there no longer is any reason
to use statfs().
The underlying kernel type is a mess, but all architectures agree on u32
(or more) for the ABI, and all filesystem magicks are 32-bit integers.
We don't lose any generality by using u32, and by doing so we both make
the API consistent with the Hurd, and allow C++
switch(f_type) { case RAMFS_MAGIC: ...; }
Also fix tst-statvfs so that it actually fails;
as it stood, all it did was return 0 always.
Test statfs()' and statvfs()' f_types are the same.

|

POSIX_SPAWN_SETCGROUP flag. They allow posix_spawn and posix_spawnp
|
|
|
|
|
|
to set the cgroupv2 in the new process in a race-free manner. These
|
|
|
|
|
|
functions are GNU extensions and require a kernel with clone3 support.

posix: Add pidfd_spawn and pidfd_spawnp (BZ 30349)
Returning a pidfd allows a process to keep a race-free handle for a
child process, otherwise, the caller will need to either use pidfd_open
(which still might be subject to TOCTOU) or keep the old racy interface
base on pid_t.
To correct use pifd_spawn, the kernel must support not only returning
the pidfd with clone/clone3 but also waitid (P_PIDFD) (added on Linux
5.4). If kernel does not support the waitid, pidfd return ENOSYS.
It avoids the need to racy workarounds, such as reading the procfs
fdinfo to get the pid to use along with other wait interfaces.
These interfaces are similar to the posix_spawn and posix_spawnp, with
the only difference being it returns a process file descriptor (int)
instead of a process ID (pid_t). Their prototypes are:
int pidfd_spawn (int *restrict pidfd,
const char *restrict file,
const posix_spawn_file_actions_t *restrict facts,
const posix_spawnattr_t *restrict attrp,
char *const argv[restrict],
char *const envp[restrict])
int pidfd_spawnp (int *restrict pidfd,
const char *restrict path,
const posix_spawn_file_actions_t *restrict facts,
const posix_spawnattr_t *restrict attrp,
char *const argv[restrict_arr],
char *const envp[restrict_arr]);
A new symbol is used instead of a posix_spawn extension to avoid
possible issues with language bindings that might track the return
argument lifetime. Although on Linux pid_t and int are interchangeable,
POSIX only states that pid_t should be a signed integer.
Both symbols reuse the posix_spawn posix_spawn_file_actions_t and
posix_spawnattr_t, to void rehash posix_spawn API or add a new one. It
also means that both interfaces support the same attribute and file
actions, and a new flag or file action on posix_spawn is also added
automatically for pidfd_spawn.
Also, using posix_spawn plumbing allows the reusing of most of the
current testing with some changes:
- waitid is used instead of waitpid since it is a more generic
interface.
- tst-posix_spawn-setsid.c is adapted to take into consideration that
the caller can check for session id directly. The test now spawns
itself and writes the session id as a file instead.
- tst-spawn3.c need to know where pidfd_spawn is used so it keeps an
extra file description unused.
Checked on x86_64-linux-gnu on Linux 4.15 (no CLONE_PIDFD or waitid
support), Linux 5.4 (full support), and Linux 6.2.

elf: Add glibc.mem.decorate_maps tunable
The PR_SET_VMA_ANON_NAME support is only enabled through a configurable
kernel switch, mainly because assigning a name to a
anonymous virtual memory area might prevent that area from being
merged with adjacent virtual memory areas.
For instance, with the following code:
void *p1 = mmap (NULL,
1024 * 4096,
PROT_READ | PROT_WRITE,
MAP_PRIVATE | MAP_ANONYMOUS,
-1,
0);
void *p2 = mmap (p1 + (1024 * 4096),
1024 * 4096,
PROT_READ | PROT_WRITE,
MAP_PRIVATE | MAP_ANONYMOUS,
-1,
0);
The kernel will potentially merge both mappings resulting in only one
segment of size 0x800000. If the segment is names with
PR_SET_VMA_ANON_NAME with different names, it results in two mappings.
Although this will unlikely be an issue for pthread stacks and malloc
arenas (since for pthread stacks the guard page will result in
a PROT_NONE segment, similar to the alignment requirement for the arena
block), it still might prevent the mmap memory allocated for detail
malloc.
There is also another potential scalability issue, where the prctl
requires
to take the mmap global lock which is still not fully fixed in Linux
[1] (for pthread stacks and arenas, it is mitigated by the stack
cached and the arena reuse).
So this patch disables anonymous mapping annotations as default and
add a new tunable, glibc.mem.decorate_maps, can be used to enable
it.

Implement C23 <stdbit.h>
C23 adds a header <stdbit.h> with various functions and type-generic
macros for bit-manipulation of unsigned integers (plus macro defines
related to endianness). Implement this header for glibc.
The functions have both inline definitions in the header (referenced
by macros defined in the header) and copies with external linkage in
the library (which are implemented in terms of those macros to avoid
duplication). They are documented in the glibc manual. Tests, as
well as verifying results for various inputs (of both the macros and
the out-of-line functions), verify the types of those results (which
showed up a bug in an earlier version with the type-generic macro
stdc_has_single_bit wrongly returning a promoted type), that the
macros can be used at top level in a source file (so don't use ({})),
that they evaluate their arguments exactly once, and that the macros
for the type-specific functions have the expected implicit conversions
to the relevant argument type.
Jakub previously referred to -Wconversion warnings in type-generic
macros, so I've included a test with -Wconversion (but the only
warnings I saw and fixed from that test were actually in inline
functions in the <stdbit.h> header - not anything coming from use of
the type-generic macros themselves).
This implementation of the type-generic macros does not handle
unsigned __int128, or unsigned _BitInt types with a width other than
that of a standard integer type (and C23 doesn't require the header to
handle such types either). Support for those types, using the new
type-generic built-in functions Jakub's added for GCC 14, can
reasonably be added in a followup (along of course with associated
tests).
This implementation doesn't do anything special to handle C++, or have
any tests of functionality in C++ beyond the existing tests that all
headers can be compiled in C++ code; it's not clear exactly what form
this header should take in C++, but probably not one using macros.
DIS ballot comment AT-107 asks for the word "count" to be added to the
names of the stdc_leading_zeros, stdc_leading_ones,
stdc_trailing_zeros and stdc_trailing_ones functions and macros. I
don't think it's likely to be accepted (accepting any technical
comments would mean having an FDIS ballot), but if it is accepted at
the WG14 meeting (22-26 January in Strasbourg, starting with DIS
ballot comment handling) then there would still be time to update
glibc for the renaming before the 2.39 release.
The new functions and header are placed in the stdlib/ directory in
glibc, rather than creating a new toplevel stdbit/ or putting them in
string/ alongside ffs.
Tested for x86_64 and x86.

The replacement for libcrypt is libxcrypt, maintained separately from
|
|
|
|
|
|
GNU libc, but available under compatible licensing terms, and providing
|
|
|
|
|
|
binary backward compatibility with the former libcrypt. It is currently
|
|
|
|
|
|
distributed from <https://github.com/besser82/libxcrypt/>.
|
|
|
|
|
|
|
|
|
|
|
|
As a consequence of this removal, GNU libc no longer makes any use of
|
|
|
|
|
|
the NSS cryptography library (Network Security Services; not to be
|
|
|
|
|
|
confused with Name Service Switch). Distributors of binary packages
|
|
|
|
|
|
of GNU libc are advised to check whether their build processes can be
|
|
|
|
|
|
simplified.

* The dynamic linker calls the malloc and free functions in more cases
|
|
|
|
|
|
during TLS access if a shared object with dynamic TLS is loaded and
|
|
|
|
|
|
unloaded. This can result in an infinite recursion if a malloc
|
|
|
|
|
|
replacement library or its dependencies use dynamic TLS instead of
|
|
|
|
|
|
initial-exec TLS.

Remove ia64-linux-gnu
Linux 6.7 removed ia64 from the official tree [1], following the general
principle that a glibc port needs upstream support for the architecture
in all the components it depends on (binutils, GCC, and the Linux
kernel).
Apart from the removal of sysdeps/ia64 and sysdeps/unix/sysv/linux/ia64,
there are updates to various comments referencing ia64 for which removal
of those references seemed appropriate. The configuration is removed
from README and build-many-glibcs.py.
The CONTRIBUTED-BY, elf/elf.h, manual/contrib.texi (the porting
mention), *.po files, config.guess, and longlong.h are not changed.
For Linux it allows cleanup some clone2 support on multiple files.
The following bug can be closed as WONTFIX: BZ 22634 [2], BZ 14250 [3],
BZ 21634 [4], BZ 10163 [5], BZ 16401 [6], and BZ 11585 [7].

Version 2.38
|
|
|
|
|
|
|
|
|
|
|
|
Major new features:
|
|
|
|
|
|
|
C2x strtol binary constant handling
C2x adds binary integer constants starting with 0b or 0B, and supports
those constants in strtol-family functions when the base passed is 0
or 2. Implement that strtol support for glibc.
As discussed at
<https://sourceware.org/pipermail/libc-alpha/2020-December/120414.html>,
this is incompatible with previous C standard versions, in that such
an input string starting with 0b or 0B was previously required to be
parsed as 0 (with the rest of the string unprocessed). Thus, as
proposed there, this patch adds 20 new __isoc23_* functions with
appropriate header redirection support. This patch does *not* do
anything about scanf %i (which will need 12 new functions per long
double variant, so 12, 24 or 36 depending on the glibc configuration),
instead leaving that for a future patch. The function names would
remain as __isoc23_* even if C2x ends up published in 2024 rather than
2023.
Making this change leads to the question of what should happen to
internal uses of these functions in glibc and its tests. The header
redirection (which applies for _GNU_SOURCE or any other feature test
macros enabling C2x features) has the effect of redirecting internal
uses but without those uses then ending up at a hidden alias (see the
comment in include/stdio.h about interaction with libc_hidden_proto).
It seems desirable for the default for internal uses to be the same
versions used by normal code using _GNU_SOURCE, so rather than doing
anything to disable that redirection, similar macro definitions to
those in include/stdio.h are added to the include/ headers for the new
functions.
Given that the default for uses in glibc is for the redirections to
apply, the next question is whether the C2x semantics are correct for
all those uses. Uses with the base fixed to 10, 16 or any other value
other than 0 or 2 can be ignored. I think this leaves the following
internal uses to consider (an important consideration for review of
this patch will be both whether this list is complete and whether my
conclusions on all entries in it are correct):
benchtests/bench-malloc-simple.c
benchtests/bench-string.h
elf/sotruss-lib.c
math/libm-test-support.c
nptl/perf.c
nscd/nscd_conf.c
nss/nss_files/files-parse.c
posix/tst-fnmatch.c
posix/wordexp.c
resolv/inet_addr.c
rt/tst-mqueue7.c
soft-fp/testit.c
stdlib/fmtmsg.c
support/support_test_main.c
support/test-container.c
sysdeps/pthread/tst-mutex10.c
I think all of these places are OK with the new semantics, except for
resolv/inet_addr.c, where the POSIX semantics of inet_addr do not
allow for binary constants; thus, I changed that file (to use
__strtoul_internal, whose semantics are unchanged) and added a test
for this case. In the case of posix/wordexp.c I think accepting
binary constants is OK since POSIX explicitly allows additional forms
of shell arithmetic expressions, and in stdlib/fmtmsg.c SEV_LEVEL is
not in POSIX so again I think accepting binary constants is OK.
Functions such as __strtol_internal, which are only exported for
compatibility with old binaries from when those were used in inline
functions in headers, have unchanged semantics; the __*_l_internal
versions (purely internal to libc and not exported) have a new
argument to specify whether to accept binary constants.
As well as for the standard functions, the header redirection also
applies to the *_l versions (GNU extensions), and to legacy functions
such as strtoq, to avoid confusing inconsistency (the *q functions
redirect to __isoc23_*ll rather than needing their own __isoc23_*
entry points). For the functions that are only declared with
_GNU_SOURCE, this means the old versions are no longer available for
normal user programs at all. An internal __GLIBC_USE_C2X_STRTOL macro
is used to control the redirections in the headers, and cases in glibc
that wish to avoid the redirections - the function implementations
themselves and the tests of the old versions of the GNU functions -
then undefine and redefine that macro to allow the old versions to be
accessed. (There would of course be greater complexity should we wish
to make any of the old versions into compat symbols / avoid them being
defined at all for new glibc ABIs.)
strtol_l.c has some similarity to strtol.c in gnulib, but has already
diverged some way (and isn't listed at all at
https://sourceware.org/glibc/wiki/SharedSourceFiles unlike strtoll.c
and strtoul.c); I haven't made any attempts at gnulib compatibility in
the changes to that file.
I note incidentally that inttypes.h and wchar.h are missing the
__nonnull present on declarations of this family of functions in
stdlib.h; I didn't make any changes in that regard for the new
declarations added.

* When C2X features are enabled and the base argument is 0 or 2, the
|
|
|
|
|
|
following functions support binary integers prefixed by 0b or 0B as
|
|
|
|
|
|
input: strtol, strtoll, strtoul, strtoull, strtol_l, strtoll_l,
|
|
|
|
|
|
strtoul_l, strtoull_l, strtoimax, strtoumax, strtoq, strtouq, wcstol,
|
|
|
|
|
|
wcstoll, wcstoul, wcstoull, wcstol_l, wcstoll_l, wcstoul_l,
|
2023-03-03 03:10:37 +08:00
|
|
|
|
wcstoull_l, wcstoimax, wcstoumax, wcstoq, wcstouq. Similarly, the
|
|
|
|
|
|
following functions support binary integers prefixed by 0b or 0B as
|
|
|
|
|
|
input to the %i format: fscanf, scanf, sscanf, vscanf, vsscanf,
|
2023-06-20 03:40:34 +08:00
|
|
|
|
vfscanf, fwscanf, wscanf, swscanf, vfwscanf, vwscanf, vswscanf; those
|
|
|
|
|
|
functions also support the %b format for binary integers, with or
|
|
|
|
|
|
without such a prefix and independent of standards mode.

2023-06-20 03:40:34 +08:00
|
|
|
|
* PRIb*, PRIB* and SCNb* macros from C2X have been added to
|
|
|
|
|
|
<inttypes.h>.

2023-03-15 00:58:35 +08:00
|
|
|
|
|
2023-06-20 02:52:12 +08:00
|
|
|
|
* printf-family functions now support the wN format length modifiers for
|
|
|
|
|
|
arguments of type intN_t, int_leastN_t, uintN_t or uint_leastN_t (for
|
|
|
|
|
|
example, %w32d to print int32_t or int_least32_t in decimal, or %w32x
|
|
|
|
|
|
to print uint32_t or uint_least32_t in hexadecimal) and the wfN format
|
|
|
|
|
|
length modifiers for arguments of type int_fastN_t or uint_fastN_t, as
|
|
|
|
|
|
specified in draft ISO C2X.
|
|
|
|
|
|
|
2023-04-14 23:12:20 +08:00
|
|
|
|
* A new tunable, glibc.pthread.stack_hugetlb, can be used to disable
|
|
|
|
|
|
Transparent Huge Pages (THP) in stack allocation at pthread_create.
|
|
|
|
|
|
|
2023-05-03 03:40:31 +08:00
|
|
|
|
* Support for x86_64 running on Hurd has been added. This port requires
|
|
|
|
|
|
as least binutils 2.40 and GCC 13:
|
|
|
|
|
|
|
|
|
|
|
|
- x86_64-gnu
|
|
|
|
|
|
|
2023-07-26 05:49:07 +08:00
|
|
|
|
* Vector math library libmvec support has been added to AArch64. It
|
|
|
|
|
|
requires GCC version >= 10.1.0. It can be disabled via
|
|
|
|
|
|
"--disable-mathvec", however that is not a supported configuration as
|
|
|
|
|
|
it changes the ABI. The symbol names follow the AArch64 vector ABI,
|
|
|
|
|
|
they are declared in math.h and have to be called manually at this point.

|
|
|
|
2023-06-15 00:10:08 +08:00
|
|
|
|
* The strlcpy and strlcat functions have been added. They are derived
|
|
|
|
|
|
from OpenBSD, and are expected to be added to a future POSIX version.
|
|
|
|
|
|
|
2023-03-17 17:14:50 +08:00
|
|
|
|
* A new configure option, "--enable-fortify-source", can be used to build the
|
|
|
|
|
|
GNU C Library with _FORTIFY_SOURCE. The level of fortification can either be
|
|
|
|
|
|
provided, or is set to the highest value supported by the compiler. If not
|
|
|
|
|
|
explicitly enabled, then fortify source is forcibly disabled so to keep
|
|
|
|
|
|
original behavior unchanged.

|
|
|
|
2023-07-31 01:43:50 +08:00
|
|
|
|
* libcrypt is no longer built by default; one may use the "--enable-crypt"
|
2023-07-18 00:44:17 +08:00
|
|
|
|
option to build libcrypt. libcrypt is likely to be removed from the
|
|
|
|
|
|
GNU C Library in a future release, so it is recommended that
|
|
|
|
|
|
applications port away from it to an alternative such as libxcrypt.
|
|
|
|
|
|
|
2023-02-26 05:59:24 +08:00
|
|
|
|
* In the Linux kernel for the hppa/parisc architecture some of the
|
|
|
|
|
|
MADV_XXX constants were changed to have the same values as the other
|
|
|
|
|
|
architectures. New programs compiled with this glibc version and which
|
|
|
|
|
|
use the madvise call will require at least Linux kernel version 6.2,
|
|
|
|
|
|
alternatively stable kernels from versions 6.1.6, 5.15.87, 5.10.163,
|
|
|
|
|
|
5.4.228, 4.19.270 or 4.14.303.

|
2023-08-01 01:54:16 +08:00
|
|
|
|
per-thread cache can still be disabled per-application using tunables
|
2023-03-29 02:46:34 +08:00

(glibc.malloc.tcache_count set to zero).
|
|
|
|
|
|
|
2023-07-26 05:49:07 +08:00
|
|

* The configure option "--enable-tunables" has been removed. The tunable
|
2023-03-23 21:13:51 +08:00

feature is now always enabled.

CVE-2023-25139: When the printf family of functions is called with a
|
|
|
|
|
|
format specifier that uses an <apostrophe> (enable grouping) and a
|
|
|
|
|
|
minimum width specifier, the resulting output could be larger than
|
|
|
|
|
|
reasonably expected by a caller that computed a tight bound on the
|
|
|
|
|
|
buffer size. The resulting larger than expected output could result
|
|
|
|
|
|
in a buffer overflow in the printf family of functions.

Major new features:

|
|
|
|
2022-02-04 02:04:22 +08:00
|
|
|
|
* Support for DT_RELR relative relocation format has been added to
|
|
|
|
|
|
glibc. This is a new ELF dynamic tag that improves the size of
|
|
|
|
|
|
relative relocations in shared object files and position independent
|
|
|
|
|
|
executables (PIE). DT_RELR generation requires linker support for
|
|
|
|
|
|
-z pack-relative-relocs option, which is supported for some targets
|
|
|
|
|
|
in recent binutils versions. Lazy binding doesn't apply to DT_RELR.

|
|
|
|
* On Linux, the pidfd_open, pidfd_getfd, and pidfd_send_signal functions
|
|
|
|
|
|
have been added. The pidfd functionality provides access to a process
|
2023-05-20 21:37:47 +08:00
|
|
|
|
while avoiding the issue of PID reuse on traditional Unix systems.

|
|
* On Linux, the process_madvise function has been added. It has the

|
|
|
|
|
same functionality as madvise but alters the target process identified
|
|
|
|
|
|
by the pidfd.
|
|
|
|
|
|
|
2022-01-28 20:53:52 +08:00
|
|
|
|
* On Linux, the process_mrelease function has been added. It allows a
|
|
|
|
|
|
caller to release the memory of a dying process. The release of the
|
|
|
|
|
|
memory is carried out in the context of the caller, using the caller's
|
|
|
|
|
|
CPU affinity, and priority with CPU usage accounted to the caller.
|
|
|
|
|
|
|
2022-06-25 00:16:41 +08:00
|
|
|
|
* The “no-aaaa” DNS stub resolver option has been added. System
|
|
|
|
|
|
administrators can use it to suppress AAAA queries made by the stub
|
|
|
|
|
|
resolver, including AAAA lookups triggered by NSS-based interfaces
|
|
|
|
|
|
such as getaddrinfo. Only DNS lookups are affected: IPv6 data in
|
|
|
|
|
|
/etc/hosts is still used, getaddrinfo with AI_PASSIVE will still
|
|
|
|
|
|
produce IPv6 addresses, and configured IPv6 name servers are still
|
|
|
|
|
|
used. To produce correct Name Error (NXDOMAIN) results, AAAA queries
|
|
|
|
|
|
are translated to A queries. The new resolver option is intended
|
|
|
|
|
|
primarily for diagnostic purposes, to rule out that AAAA DNS queries
|
|
|
|
|
|
have adverse impact. It is incompatible with EDNS0 usage and DNSSEC
|
|
|
|
|
|
validation by applications.

|
|
|
|
|
|
2022-06-25 03:59:19 +08:00

|
|
|
* On Linux, the fsopen, fsmount, move_mount, fsconfig, fspick, open_tree,
|
|
|
|
|
|
and mount_setattr have been added. They are part of the new Linux kernel
|
|
|
|
|
|
mount APIs that allow applications to more flexibly configure and operate
|
|
|
|
|
|
on filesystem mounts. The new mount APIs are specifically designed to work
|
2022-06-25 03:59:17 +08:00
|
|
|
|
with namespaces.

stdlib: Add arc4random, arc4random_buf, and arc4random_uniform (BZ #4417)
The implementation is based on scalar Chacha20 with per-thread cache.
It uses getrandom or /dev/urandom as fallback to get the initial entropy,
and reseeds the internal state on every 16MB of consumed buffer.
To improve performance and lower memory consumption the per-thread cache
is allocated lazily on first arc4random functions call, and if the
memory allocation fails getentropy or /dev/urandom is used as fallback.
The cache is also cleared on thread exit iff it was initialized (so if
arc4random is not called it is not touched).
Although it is lock-free, arc4random is still not async-signal-safe
(the per thread state is not updated atomically).
The ChaCha20 implementation is based on RFC8439 [1], omitting the final
XOR of the keystream with the plaintext because the plaintext is a
stream of zeros. This strategy is similar to what OpenBSD arc4random
does.
The arc4random_uniform is based on previous work by Florian Weimer,
where the algorithm is based on Jérémie Lumbroso paper Optimal Discrete
Uniform Generation from Coin Flips, and Applications (2013) [2], who
credits Donald E. Knuth and Andrew C. Yao, The complexity of nonuniform
random number generation (1976), for solving the general case.
The main advantage of this method is the that the unit of randomness is not
the uniform random variable (uint32_t), but a random bit. It optimizes the
internal buffer sampling by initially consuming a 32-bit random variable
and then sampling byte per byte. Depending of the upper bound requested,
it might lead to better CPU utilization.
Checked on x86_64-linux-gnu, aarch64-linux, and powerpc64le-linux-gnu.

arc4random: simplify design for better safety
Rather than buffering 16 MiB of entropy in userspace (by way of
chacha20), simply call getrandom() every time.
This approach is doubtlessly slower, for now, but trying to prematurely
optimize arc4random appears to be leading toward all sorts of nasty
properties and gotchas. Instead, this patch takes a much more
conservative approach. The interface is added as a basic loop wrapper
around getrandom(), and then later, the kernel and libc together can
work together on optimizing that.
This prevents numerous issues in which userspace is unaware of when it
really must throw away its buffer, since we avoid buffering all
together. Future improvements may include userspace learning more from
the kernel about when to do that, which might make these sorts of
chacha20-based optimizations more possible. The current heuristic of 16
MiB is meaningless garbage that doesn't correspond to anything the
kernel might know about. So for now, let's just do something
conservative that we know is correct and won't lead to cryptographic
issues for users of this function.
This patch might be considered along the lines of, "optimization is the
root of all evil," in that the much more complex implementation it
replaces moves too fast without considering security implications,
whereas the incremental approach done here is a much safer way of going
about things. Once this lands, we can take our time in optimizing this
properly using new interplay between the kernel and userspace.
getrandom(0) is used, since that's the one that ensures the bytes
returned are cryptographically secure. But on systems without it, we
fallback to using /dev/urandom. This is unfortunate because it means
opening a file descriptor, but there's not much of a choice. Secondly,
as part of the fallback, in order to get more or less the same
properties of getrandom(0), we poll on /dev/random, and if the poll
succeeds at least once, then we assume the RNG is initialized. This is a
rough approximation, as the ancient "non-blocking pool" initialized
after the "blocking pool", not before, and it may not port back to all
ancient kernels, though it does to all kernels supported by glibc
(≥3.2), so generally it's the best approximation we can do.
The motivation for including arc4random, in the first place, is to have
source-level compatibility with existing code. That means this patch
doesn't attempt to litigate the interface itself. It does, however,
choose a conservative approach for implementing it.

Add generic C.UTF-8 locale (Bug 17318)
We add a new C.UTF-8 locale. This locale is not builtin to glibc, but
is provided as a distinct locale. The locale provides full support for
UTF-8 and this includes full code point sorting via STRCMP-based
collation (strcmp or wcscmp).
The collation uses a new keyword 'codepoint_collation' which drops all
collation rules and generates an empty zero rules collation to enable
STRCMP usage in collation. This ensures that we get full code point
sorting for C.UTF-8 with a minimal 1406 bytes of overhead (LC_COLLATE
structure information and ASCII collating tables).
The new locale is added to SUPPORTED. Minimal test data for specific
code points (minus those not supported by collate-test) is provided in
C.UTF-8.in, and this verifies code point sorting is working reasonably
across the range. The locale was tested manually with the full set of
code points without failure.
The locale is harmonized with locales already shipping in various
downstream distributions. A new tst-iconv9 test is added which verifies
the C.UTF-8 locale is generally usable.
Testing for fnmatch, regexec, and recomp is provided by extending
bug-regex1, bugregex19, bug-regex4, bug-regex6, transbug, tst-fnmatch,
tst-regcomp-truncated, and tst-regex to use C.UTF-8.
Tested on x86_64 or i686 without regression.

* Support for the C.UTF-8 locale has been added to glibc. The locale
|
|
|
|
|
|
supports full code-point sorting for all valid Unicode code points. A
|
|

limitation in the framework for fnmatch, regexec, and regcomp requires
|

a compromise to save space and only ASCII-based range expressions are

|
|
supported for now (see bug 28255). The full size of the locale is
|

only ~400KiB, with 346KiB coming from LC_CTYPE information for
|
|
|

Add narrowing square root functions
This patch adds the narrowing square root functions from TS 18661-1 /
TS 18661-3 / C2X to glibc's libm: fsqrt, fsqrtl, dsqrtl, f32sqrtf64,
f32sqrtf32x, f32xsqrtf64 for all configurations; f32sqrtf64x,
f32sqrtf128, f64sqrtf64x, f64sqrtf128, f32xsqrtf64x, f32xsqrtf128,
f64xsqrtf128 for configurations with _Float64x and _Float128;
__f32sqrtieee128 and __f64sqrtieee128 aliases in the powerpc64le case
(for calls to fsqrtl and dsqrtl when long double is IEEE binary128).
Corresponding tgmath.h macro support is also added.
The changes are mostly similar to those for the other narrowing
functions previously added, so the description of those generally
applies to this patch as well. However, the not-actually-narrowing
cases (where the two types involved in the function have the same
floating-point format) are aliased to sqrt, sqrtl or sqrtf128 rather
than needing a separately built not-actually-narrowing function such
as was needed for add / sub / mul / div. Thus, there is no
__nldbl_dsqrtl name for ldbl-opt because no such name was needed
(whereas the other functions needed such a name since the only other
name for that entry point was e.g. f32xaddf64, not reserved by TS
18661-1); the headers are made to arrange for sqrt to be called in
that case instead.
The DIAG_* calls in sysdeps/ieee754/soft-fp/s_dsqrtl.c are because
they were observed to be needed in GCC 7 testing of
riscv32-linux-gnu-rv32imac-ilp32. The other sysdeps/ieee754/soft-fp/
files added didn't need such DIAG_* in any configuration I tested with
build-many-glibcs.py, but if they do turn out to be needed in more
files with some other configuration / GCC version, they can always be
added there.
I reused the same test inputs in auto-libm-test-in as for
non-narrowing sqrt rather than adding extra or separate inputs for
narrowing sqrt. The tests in libm-test-narrow-sqrt.inc also follow
those for non-narrowing sqrt.
Tested as followed: natively with the full glibc testsuite for x86_64
(GCC 11, 7, 6) and x86 (GCC 11); with build-many-glibcs.py with GCC
11, 7 and 6; cross testing of math/ tests for powerpc64le, powerpc32
hard float, mips64 (all three ABIs, both hard and soft float). The
different GCC versions are to cover the different cases in tgmath.h
and tgmath.h tests properly (GCC 6 has _Float* only as typedefs in
glibc headers, GCC 7 has proper _Float* support, GCC 8 adds
__builtin_tgmath).

|
|
* <math.h> functions that round their results to a narrower type, and
|
|
|
|
|
|
corresponding <tgmath.h> macros, are added from TS 18661-1:2014, TS
|
|
|
|
|
|
18661-3:2015 and draft ISO C2X:
|
|
|
|
|
|
|
|
|
|
|
|
- fsqrt, fsqrtl, dsqrtl and corresponding fMsqrtfN, fMsqrtfNx,
|
|
|
|
|
|
fMxsqrtfN and fMxsqrtfNx functions.

Add narrowing fma functions
This patch adds the narrowing fused multiply-add functions from TS
18661-1 / TS 18661-3 / C2X to glibc's libm: ffma, ffmal, dfmal,
f32fmaf64, f32fmaf32x, f32xfmaf64 for all configurations; f32fmaf64x,
f32fmaf128, f64fmaf64x, f64fmaf128, f32xfmaf64x, f32xfmaf128,
f64xfmaf128 for configurations with _Float64x and _Float128;
__f32fmaieee128 and __f64fmaieee128 aliases in the powerpc64le case
(for calls to ffmal and dfmal when long double is IEEE binary128).
Corresponding tgmath.h macro support is also added.
The changes are mostly similar to those for the other narrowing
functions previously added, especially that for sqrt, so the
description of those generally applies to this patch as well. As with
sqrt, I reused the same test inputs in auto-libm-test-in as for
non-narrowing fma rather than adding extra or separate inputs for
narrowing fma. The tests in libm-test-narrow-fma.inc also follow
those for non-narrowing fma.
The non-narrowing fma has a known bug (bug 6801) that it does not set
errno on errors (overflow, underflow, Inf * 0, Inf - Inf). Rather
than fixing this or having narrowing fma check for errors when
non-narrowing does not (complicating the cases when narrowing fma can
otherwise be an alias for a non-narrowing function), this patch does
not attempt to check for errors from narrowing fma and set errno; the
CHECK_NARROW_FMA macro is still present, but as a placeholder that
does nothing, and this missing errno setting is considered to be
covered by the existing bug rather than needing a separate open bug.
missing-errno annotations are duly added to many of the
auto-libm-test-in test inputs for fma.
This completes adding all the new functions from TS 18661-1 to glibc,
so will be followed by corresponding stdc-predef.h changes to define
__STDC_IEC_60559_BFP__ and __STDC_IEC_60559_COMPLEX__, as the support
for TS 18661-1 will be at a similar level to that for C standard
floating-point facilities up to C11 (pragmas not implemented, but
library functions done). (There are still further changes to be done
to implement changes to the types of fromfp functions from N2548.)
Tested as followed: natively with the full glibc testsuite for x86_64
(GCC 11, 7, 6) and x86 (GCC 11); with build-many-glibcs.py with GCC
11, 7 and 6; cross testing of math/ tests for powerpc64le, powerpc32
hard float, mips64 (all three ABIs, both hard and soft float). The
different GCC versions are to cover the different cases in tgmath.h
and tgmath.h tests properly (GCC 6 has _Float* only as typedefs in
glibc headers, GCC 7 has proper _Float* support, GCC 8 adds
__builtin_tgmath).

Add fmaximum, fminimum functions
C2X adds new <math.h> functions for floating-point maximum and
minimum, corresponding to the new operations that were added in IEEE
754-2019 because of concerns about the old operations not being
associative in the presence of signaling NaNs. fmaximum and fminimum
handle NaNs like most <math.h> functions (any NaN argument means the
result is a quiet NaN). fmaximum_num and fminimum_num handle both
quiet and signaling NaNs the way fmax and fmin handle quiet NaNs (if
one argument is a number and the other is a NaN, return the number),
but still raise "invalid" for a signaling NaN argument, making them
exceptions to the normal rule that a function with a floating-point
result raising "invalid" also returns a quiet NaN. fmaximum_mag,
fminimum_mag, fmaximum_mag_num and fminimum_mag_num are corresponding
functions returning the argument with greatest or least absolute
value. All these functions also treat +0 as greater than -0. There
are also corresponding <tgmath.h> type-generic macros.
Add these functions to glibc. The implementations use type-generic
templates based on those for fmax, fmin, fmaxmag and fminmag, and test
inputs are based on those for those functions with appropriate
adjustments to the expected results. The RISC-V maintainers might
wish to add optimized versions of fmaximum_num and fminimum_num (for
float and double), since RISC-V (F extension version 2.2 and later)
provides instructions corresponding to those functions - though it
might be at least as useful to add architecture-independent built-in
functions to GCC and teach the RISC-V back end to expand those
functions inline, which is what you generally want for functions that
can be implemented with a single instruction.
Tested for x86_64 and x86, and with build-many-glibcs.py.

Define __STDC_IEC_60559_BFP__ and __STDC_IEC_60559_COMPLEX__
TS 18661-1 and C2X specify predefined macros __STDC_IEC_60559_BFP__
and __STDC_IEC_60559_COMPLEX__, making __STDC_IEC_559__ and
__STDC_IEC_559_COMPLEX__ obsolescent (but still included in the
standard). Now that we have all the functions from TS 18661-1, define
these macros in stdc-predef.h, under the same conditions in which the
older macros are defined, since support for the floating-point
features in TS 18661-1 is now at the same level as that for those in
C11 and before (all library functions and other library APIs present,
but no standard pragma support).
The macros are defined for now with their TS 18661-1 values. C2X will
give them new values (listed as yyyymmL in the working drafts until
the final standard), at which point there will be the question of what
value to use in stdc-predef.h (where it could depend on
__STDC_VERSION__, but not on feature test macros defined by the user).
My inclination then would be to use the C2X value unconditionally
rather than using an older value to indicate TS support, and only have
any C standard version conditionals for the value when subsequent C
standard versions define further values.
(Note that I'm also inclined, when we implement the C2X change to the
return types of fromfp functions, to make that change unconditional
much like the change made to the types of totalorder functions, with
the old version only supported with compat symbols for already-linked
programs and not as an API for newly built objects. So using the C2X
value would also accurately reflect not supporting the versions of
APIs in the TS where those ended up being incompatible with the first
version actually added to the standard.)
Tested for x86_64.

Support C2X printf %b, %B
C2X adds a printf %b format (see
<http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2630.pdf>, accepted
for C2X), for outputting integers in binary. It also has recommended
practice for a corresponding %B format (like %b, but %#B starts the
output with 0B instead of 0b). Add support for these formats to
glibc.
One existing test uses %b as an example of an unknown format, to test
how glibc printf handles unknown formats; change that to %v. Use of
%b and %B as user-registered format specifiers continues to work (and
we already have a test that covers that, tst-printfsz.c).
Note that C2X also has scanf %b support, plus support for binary
constants starting 0b in strtol (base 0 and 2) and scanf %i (strtol
base 0 and scanf %i coming from a previous paper that added binary
integer literals). I intend to implement those features in a separate
patch or patches; as discussed in the thread starting at
<https://sourceware.org/pipermail/libc-alpha/2020-December/120414.html>,
they will be more complicated because they involve adding extra public
symbols to ensure compatibility with existing code that might not
expect 0b constants to be handled by strtol base 0 and 2 and scanf %i,
whereas simply adding a new format specifier poses no such
compatibility concerns.
Note that the actual conversion from integer to string uses existing
code in _itoa.c. That code has special cases for bases 8, 10 and 16,
probably so that the compiler can optimize division by an integer
constant in the code for those bases. If desired such special cases
could easily be added for base 2 as well, but that would be an
optimization, not actually needed for these printf formats to work.
Tested for x86_64 and x86. Also tested with build-many-glibcs.py for
aarch64-linux-gnu with GCC mainline to make sure that the test does
indeed build with GCC 12 (where format checking warnings are enabled
for most of the test).

operations on per-cpu data. It allows user-space to perform updates

* On Linux, a new tunable, glibc.malloc.hugetlb, can be used to
|
malloc: Add Huge Page support for mmap
With the morecore hook removed, there is not easy way to provide huge
pages support on with glibc allocator without resorting to transparent
huge pages. And some users and programs do prefer to use the huge pages
directly instead of THP for multiple reasons: no splitting, re-merging
by the VM, no TLB shootdowns for running processes, fast allocation
from the reserve pool, no competition with the rest of the processes
unlike THP, no swapping all, etc.
This patch extends the 'glibc.malloc.hugetlb' tunable: the value
'2' means to use huge pages directly with the system default size,
while a positive value means and specific page size that is matched
against the supported ones by the system.
Currently only memory allocated on sysmalloc() is handled, the arenas
still uses the default system page size.
To test is a new rule is added tests-malloc-hugetlb2, which run the
addes tests with the required GLIBC_TUNABLE setting. On systems without
a reserved huge pages pool, is just stress the mmap(MAP_HUGETLB)
allocation failure. To improve test coverage it is required to create
a pool with some allocated pages.
Checked on x86_64-linux-gnu.

|
posix: Add terminal control setting support for posix_spawn
Currently there is no proper way to set the controlling terminal through
posix_spawn in race free manner [1]. This forces shell implementations
to keep using fork+exec when launching background process groups,
even when using posix_spawn yields better performance.
This patch adds a new GNU extension so the creating process can
configure the created process terminal group. This is done with a new
flag, POSIX_SPAWN_TCSETPGROUP, along with two new attribute functions:
posix_spawnattr_tcsetpgrp_np, and posix_spawnattr_tcgetpgrp_np.
The function sets a new attribute, spawn-tcgroupfd, that references to
the controlling terminal.
The controlling terminal is set after the spawn-pgroup attribute, and
uses the spawn-tcgroupfd along with current creating process group
(so it is composable with POSIX_SPAWN_SETPGROUP).
To create a process and set the controlling terminal, one can use the
following sequence:
posix_spawnattr_t attr;
posix_spawnattr_init (&attr);
posix_spawnattr_setflags (&attr, POSIX_SPAWN_TCSETPGROUP);
posix_spawnattr_tcsetpgrp_np (&attr, tcfd);
If the idea is also to create a new process groups:
posix_spawnattr_t attr;
posix_spawnattr_init (&attr);
posix_spawnattr_setflags (&attr, POSIX_SPAWN_TCSETPGROUP
| POSIX_SPAWN_SETPGROUP);
posix_spawnattr_tcsetpgrp_np (&attr, tcfd);
posix_spawnattr_setpgroup (&attr, 0);
The controlling terminal file descriptor is ignored if the new flag is
not set.
This interface is slight different than the one provided by QNX [2],
which only provides the POSIX_SPAWN_TCSETPGROUP flag. The QNX
documentation does not specify how the controlling terminal is obtained
nor how it iteracts with POSIX_SPAWN_SETPGROUP. Since a glibc
implementation is library based, it is more straightforward and avoid
requires additional file descriptor operations to request the caller
to setup the controlling terminal file descriptor (and it also allows
a bit less error handling by posix_spawn).
Checked on x86_64-linux-gnu and i686-linux-gnu.

Version 2.34

Major new features:

|
|
|
|
2021-08-01 11:39:07 +08:00
|
|
|
|
* In order to support smoother in-place-upgrades and to simplify
|
|
|
|
|
|
the implementation of the runtime all functionality formerly
|
|
|
|
|
|
implemented in the libraries libpthread, libdl, libutil, libanl has
|
|
|
|
|
|
been integrated into libc. New applications do not need to link with
|
|
|
|
|
|
-lpthread, -ldl, -lutil, -lanl anymore. For backwards compatibility,
|
|
|
|
|
|
empty static archives libpthread.a, libdl.a, libutil.a, libanl.a are
|
|
|
|
|
|
provided, so that the linker options keep working. Applications which
|
|
|
|
|
|
have been linked against glibc 2.33 or earlier continue to load the
|
|
|
|
|
|
corresponding shared objects (which are now empty). The integration
|
|
|
|
|
|
of those libraries into libc means that additional symbols become
|
|
|
|
|
|
available by default. This can cause applications that contain weak
|
|
|
|
|
|
references to take unexpected code paths that would only have been
|
|
|
|
|
|
used in previous glibc versions when e.g. preloading libpthread.so.0,
|
|
|
|
|
|
potentially exposing application bugs.

2021-06-22 03:42:56 +08:00
|
|
|
|
* When _DYNAMIC_STACK_SIZE_SOURCE or _GNU_SOURCE are defined,
|
|
|
|
|
|
PTHREAD_STACK_MIN is no longer constant and is redefined to
|
2021-08-01 11:39:07 +08:00
|
|
|
|
sysconf(_SC_THREAD_STACK_MIN). This supports dynamic sized register
|
|
|
|
|
|
sets for modern architectural features like Arm SVE.
|
2021-06-22 03:42:56 +08:00
|
|
|
|
|
|
|

|
|
* Add _SC_MINSIGSTKSZ and _SC_SIGSTKSZ. When _DYNAMIC_STACK_SIZE_SOURCE
|
|
|
|
|
|
or _GNU_SOURCE are defined, MINSIGSTKSZ and SIGSTKSZ are no longer
|
2021-02-02 07:50:51 +08:00
|
|
|
|
constant on Linux. MINSIGSTKSZ is redefined to sysconf(_SC_MINSIGSTKSZ)
|
2021-08-01 11:39:07 +08:00
|
|
|
|
and SIGSTKSZ is redefined to sysconf (_SC_SIGSTKSZ). This supports
|
|
|
|
|

dynamic sized register sets for modern architectural features like
|
|
|
|
|

|
glibc-hwcaps subdirectory selection.

|
|
|
2021-05-04 00:35:10 +08:00
|
|
|
|
* On Linux, the function execveat has been added. It operates similar to
|
|
|
|
|
|
execve and it is is already used to implement fexecve without requiring
|
|
|
|
|
|
/proc to be mounted. However, different than fexecve, if the syscall is not
|
|
|
|
|
|
supported by the kernel an error is returned instead of trying a fallback.
|
|
|
|
|
|
|
2021-05-18 04:55:21 +08:00
|
|
|
|
* The ISO C2X function timespec_getres has been added.
|
|
|
|
|
|
|
Update floating-point feature test macro handling for C2X
ISO C2X has made some changes to the handling of feature test macros
related to features from the floating-point TSes, and to exactly what
such features are present in what headers, that require corresponding
changes in glibc.
* For the few features that were controlled by
__STDC_WANT_IEC_60559_BFP_EXT__ (and the corresponding DFP macro) in
C2X, there is now instead a new feature test macro
__STDC_WANT_IEC_60559_EXT__ covering both binary and decimal FP.
This controls CR_DECIMAL_DIG in <float.h> (provided by GCC; I
implemented support for the new feature test macro for GCC 11) and
the totalorder and payload functions in <math.h>. C2X no longer
says anything about __STDC_WANT_IEC_60559_BFP_EXT__ (so it's
appropriate for that macro to continue to enable exactly the
features from TS 18661-1).
* The SNAN macros for each floating-point type have moved to <float.h>
(and been renamed in the process). Thus, the copies in <math.h>
should only be defined for __STDC_WANT_IEC_60559_BFP_EXT__, not for
C2X.
* The fmaxmag and fminmag functions have been removed (replaced by new
functions for the new min/max operations in IEEE 754-2019). Thus
those should also only be declared for
__STDC_WANT_IEC_60559_BFP_EXT__.
* The _FloatN / _FloatNx handling for the last two points in glibc is
trickier, since __STDC_WANT_IEC_60559_TYPES_EXT__ is still in C2X
(the integration of TS 18661-3 as an Annex, that is, which hasn't
yet been merged into the C standard git repository but has been
accepted by WG14), so C2X with that macro should not declare some
things that are declared for older standards with that macro. The
approach taken here is to provide the declarations (when
__STDC_WANT_IEC_60559_TYPES_EXT__ is enabled) only when (defined
__USE_GNU || !__GLIBC_USE (ISOC2X)), so if C2X features are enabled
then those declarations (that are only in TS 18661-3 and not in C2X)
will only be provided if _GNU_SOURCE is defined as well. Thus
_GNU_SOURCE remains a superset of the TS features as well as of C2X.
Some other somewhat related changes in C2X are not addressed here.
There's an open proposal not to include the fmin and fmax functions
for the _FloatN / _FloatNx types, given the new min/max operations,
which could be handled like the previous point if adopted. And the
fromfp functions have been changed to return a result in floating type
rather than intmax_t / uintmax_t; my inclination there is to treat
that like that change of totalorder type (new symbol versions etc. for
the ABI change; old versions become compat symbols and are no longer
supported as an API).
Tested for x86_64 and x86.
2021-06-01 22:22:06 +08:00
|
|
|
|
* The feature test macro __STDC_WANT_IEC_60559_EXT__, from draft ISO
|
|
|
|
|
|
C2X, is supported to enable declarations of functions defined in Annex F
|
|
|
|
|
|
of C2X. Those declarations are also enabled when
|
|
|
|
|
|
__STDC_WANT_IEC_60559_BFP_EXT__, as specified in TS 18661-1, is
|
|
|
|
|
|
defined, and when _GNU_SOURCE is defined.

|
|
|
|
* On powerpc64*, glibc can now be compiled without scv support using the
|
|
|
|
|
|
--disable-scv configure option.
|
|
|
|
|
|
|
2021-06-25 12:12:19 +08:00
|
|
|
|
* Add support for 64-bit time_t on configurations like x86 where time_t
|
|
|
|
|
|
is traditionally 32-bit. Although time_t still defaults to 32-bit on
|
|
|
|
|
|
these configurations, this default may change in future versions.
|
2021-08-01 07:25:57 +08:00
|
|
|
|
This is enabled with the _TIME_BITS preprocessor macro set to 64 and is
|
|
|
|
|
|
only supported when LFS (_FILE_OFFSET_BITS=64) is also enabled. It is
|
|
|
|
|
|
only enabled for Linux and the full support requires a minimum kernel
|
|
|
|
|
|
version of 5.1.
|
y2038: Add support for 64-bit time on legacy ABIs
A new build flag, _TIME_BITS, enables the usage of the newer 64-bit
time symbols for legacy ABI (where 32-bit time_t is default). The 64
bit time support is only enabled if LFS (_FILE_OFFSET_BITS=64) is
also used.
Different than LFS support, the y2038 symbols are added only for the
required ABIs (armhf, csky, hppa, i386, m68k, microblaze, mips32,
mips64-n32, nios2, powerpc32, sparc32, s390-32, and sh). The ABIs with
64-bit time support are unchanged, both for symbol and types
redirection.
On Linux the full 64-bit time support requires a minimum of kernel
version v5.1. Otherwise, the 32-bit fallbacks are used and might
results in error with overflow return code (EOVERFLOW).
The i686-gnu does not yet support 64-bit time.

* The main gconv-modules file in glibc now contains only a small set of
|
|
|
|
|
|
essential converter modules and the rest have been moved into a supplementary
|
|
|
|
|

configuration file gconv-modules-extra.conf in the gconv-modules.d directory
|
|
|
|

|
in the same GCONV_PATH. Similarly, external converter modules directories

* The function _Fork has been added as an async-signal-safe fork replacement
|
2023-05-20 21:37:47 +08:00
|
|
|

since Austin Group issue 62 dropped the async-signal-safe requirement for
|
2021-01-19 20:26:31 +08:00
|
|
|
|
fork (and it will be included in the future POSIX standard). The new _Fork
|
|
|
|
|
|
function does not run any atfork function neither resets any internal state
|
|
|
|
|
|
or lock (such as the malloc one), and only sets up a minimal state required
|
|
|
|
|
|
to call async-signal-safe functions (such as raise or execve). This function
|
|
|
|
|
|
is currently a GNU extension.

* On Linux, the close_range function has been added. It allows efficiently
|
|
|
|
|
|
closing a range of file descriptors on recent kernels (version 5.9).
|
|
|
|
|
|
|
io: Add closefrom [BZ #10353]
The function closes all open file descriptors greater than or equal to
input argument. Negative values are clamped to 0, i.e, it will close
all file descriptors.
As indicated by the bug report, this is a common symbol provided by
different systems (Solaris, OpenBSD, NetBSD, FreeBSD) and, although
its has inherent issues with not taking in consideration internal libc
file descriptors (such as syslog), this is also a common feature used
in multiple projects [1][2][3][4][5].
The Linux fallback implementation iterates over /proc and close all
file descriptors sequentially. Although it was raised the questioning
whether getdents on /proc/self/fd might return disjointed entries
when file descriptor are closed; it does not seems the case on my
testing on multiple kernel (v4.18, v5.4, v5.9) and the same strategy
is used on different projects [1][2][3][5].
Also, the interface is set a fail-safe meaning that a failure in the
fallback results in a process abort.
Checked on x86_64-linux-gnu and i686-linux-gnu on kernel 5.11 and 4.15.

in multiple projects [1][2][3][4][5].
The Linux fallback implementation iterates over /proc and close all
file descriptors sequentially. Although it was raised the questioning
whether getdents on /proc/self/fd might return disjointed entries
when file descriptor are closed; it does not seems the case on my
testing on multiple kernel (v4.18, v5.4, v5.9) and the same strategy
is used on different projects [1][2][3][5].
Also, the interface is set a fail-safe meaning that a failure in the
fallback results in a process abort.
Checked on x86_64-linux-gnu and i686-linux-gnu on kernel 5.11 and 4.15.

resolv: Deprecate legacy interfaces in libresolv
Debugging interfaces: p_*, fp_*, and sym_* could conceivably be
used to produce debug out, but these functions have not been
updated to parse more resource records, so they are not very useful
today. Likewise for ns_sprintrr and ns_sprintrrf. ns_format_ttl and
ns_parse_ttl are related to these.
Internal implementation details: res_isourserver is probably only
useful in the implementation of a stub resolver, and so is
res_nameinquery.
Unclear semantics and bad performance: ns_samedomain, ns_subdomain,
ns_makecanon, ns_samename do textual converions & copies instead of
checking equivalence of the wire format.
inet_neta cannot handle IPv6 addresses.
res_hostalias has been superseded by getaddrinfo with AI_CANONNAME.
hostalias is not thread-safe.
Some functions have int as size arguments instead of size_t, so they
do not follow current coding practices. However, dn_expand and
b64_ntop are somewhat widely used (to name just two examples), so
deprecating them seems problematic.

* Various symbols previously defined in libresolv have been moved to libc
|
|
|
|
|
|
in order to prepare for libresolv moving entirely into libc (see earlier
|
|
|
|
|
|
entry for merging libraries into libc). The symbols __dn_comp,
|
|
|
|
|
|
__dn_expand, __dn_skipname, __res_dnok, __res_hnok, __res_mailok,
|
|
|

__res_mkquery, __res_nmkquery, __res_nquery, __res_nquerydomain,

__res_nsearch, __res_nsend, __res_ownok, __res_query, __res_querydomain,
|
|

* The pthread cancellation handler is now installed with SA_RESTART and

|
|
pthread_cancel will always send the internal SIGCANCEL on a cancellation
|
2021-08-01 07:25:57 +08:00
|
|
|
|
request. It should not be visible to applications since the cancellation
|
2021-06-17 20:45:03 +08:00
|
|
|
|
handler should either act upon cancellation (if asynchronous cancellation
|
|
|
|
|
|
is enabled) or ignore the cancellation internal signal. However there are
|
2021-08-01 07:25:57 +08:00
|
|
|
|
buggy kernel interfaces (for instance some CIFS versions) that could still
|
|
|
|
|
|
see a spurious EINTR error when cancellation interrupts a blocking syscall.

|
|
|
|
* Previously, glibc installed its various shared objects under versioned
|
|
|
|
|
|
file names such as libc-2.33.so. The ABI sonames (e.g., libc.so.6)
|
|
|
|
|
|
were provided as symbolic links. Starting with glibc 2.34, the shared
|
|
|
|
|
|
objects are installed under their ABI sonames directly, without
|
|
|
|
|
|
symbolic links. This increases compatibility with distribution
|
|
|
|
|
|
package managers that delete removed files late during the package
|
|
|
|
|
|
upgrade or downgrade process.

|

|
|
|
|
2021-07-03 03:17:34 +08:00
|
|
|
|
* The symbols mallwatch and tr_break are now deprecated and no longer used in
|
|
|
|
|
|
mtrace. Similar functionality can be achieved by using conditional
|
|
|
|
|
|
breakpoints within mtrace functions from within gdb.

|
|
|
2021-07-22 21:07:57 +08:00
|
|
|
|
* The __morecore and __after_morecore_hook malloc hooks and the default
|
|
|
|
|
|
implementation __default_morecore have been removed from the API. Existing
|
|
|
|
|
|
applications will continue to link against these symbols but the interfaces
|
|
|
|
|
|
no longer have any effect on malloc.

* Debugging features in malloc such as the MALLOC_CHECK_ environment variable
|
|
|
|
|
|
(or the glibc.malloc.check tunable), mtrace() and mcheck() have now been
|
|
|
|
|
|
disabled by default in the main C library. Users looking to use these
|
|
|
|
|
|
features now need to preload a new debugging DSO libc_malloc_debug.so to get
|
|
|
|
|
|
this functionality back.
|
|
|
|
|
|
|
2021-07-22 21:08:10 +08:00
|
|
|
|
* The deprecated functions malloc_get_state and malloc_set_state have been
|
|
|
|
|
|
moved from the core C library into libc_malloc_debug.so. Legacy applications
|
|
|
|
|
|
that still use these functions will now need to preload libc_malloc_debug.so
|
|
|
|
|
|
in their environment using the LD_PRELOAD environment variable.
|
|
|
|
|
|
|
2021-07-22 21:08:12 +08:00
|
|
|
|
* The deprecated memory allocation hooks __malloc_hook, __realloc_hook,
|
|
|
|
|
|
__memalign_hook and __free_hook are now removed from the API. Compatibility
|
|
|
|
|
|
symbols are present to support legacy programs but new applications can no
|
|
|
|
|
|
longer link to these symbols. These hooks no longer have any effect on glibc
|
|
|
|
|
|
functionality. The malloc debugging DSO libc_malloc_debug.so currently
|
|
|
|
|
|
supports hooks and can be preloaded to get this functionality back for older
|
|
|
|
|
|
programs. However this is a transitional measure and may be removed in a
|
|
|
|
|
|
future release of the GNU C Library. Users may port away from these hooks by
|
|
|
|
|
|
writing and preloading their own malloc interposition library.

* On Linux, the shm_open, sem_open, and related functions now expect the
|
|
|
|
|
|
file shared memory file system to be mounted at /dev/shm. These functions
|
|
|
|
|
|
no longer search among the system's mount points for a suitable
|
|
|
|
|
|
replacement if /dev/shm is not available.

Version 2.33
|
|
|
|
|
|
|
|
|
|
|
|
Major new features:
|
|
|
|
|
|
|
2020-07-12 21:04:53 +08:00
|
|
|
|
* The dynamic linker accepts the --list-tunables argument which prints
|
|
|
|
|
|
all the supported tunables. This option is disable if glibc is
|
|
|
|
|
|
configured with tunables disabled (--enable-tunables=no).
|
|
|
|
|
|
|
2020-09-29 18:34:39 +08:00
|
|
|
|
* The dynamic linker accepts the --argv0 argument and provides opportunity
|
|
|
|
|
|
to change argv[0] string.
|
|
|
|
|
|
|
2021-01-30 00:26:18 +08:00
|
|
|
|
* The dynamic linker loads optimized implementations of shared objects
|
|
|
|
|
|
from subdirectories under the glibc-hwcaps directory on the library
|
|
|
|
|
|
search path if the system's capabilities meet the requirements for
|
|
|
|
|
|
that subdirectory. Initially supported subdirectories include
|
|
|
|
|
|
"power9" and "power10" for the powerpc64le-linux-gnu architecture,
|
|
|
|
|
|
"z13", "z14", "z15" for s390x-linux-gnu, and "x86-64-v2", "x86-64-v3",
|
|
|
|
|
|
"x86-64-v4" for x86_64-linux-gnu. In the x86_64-linux-gnu case, the
|
|
|
|
|
|
subdirectory names correspond to the vendor-independent x86-64
|
|
|
|
|
|
microarchitecture levels defined in the x86-64 psABI supplement.
|
|
|
|
|
|
|
|
|
|
|
|
* The new --help option of the dynamic linker provides usage and
|
|
|
|
|
|
information and library search path diagnostics.
|
|
|
|
|
|
|
2020-09-02 04:17:25 +08:00
|
|
|
|
* The mallinfo2 function is added to report statistics as per mallinfo,
|
|
|
|
|
|
but with larger field widths to accurately report values that are
|
|
|
|
|
|
larger than fit in an integer.

x86: Install <sys/platform/x86.h> [BZ #26124]
Install <sys/platform/x86.h> so that programmers can do
#if __has_include(<sys/platform/x86.h>)
#include <sys/platform/x86.h>
#endif
...
if (CPU_FEATURE_USABLE (SSE2))
...
if (CPU_FEATURE_USABLE (AVX2))
...
<sys/platform/x86.h> exports only:
enum
{
COMMON_CPUID_INDEX_1 = 0,
COMMON_CPUID_INDEX_7,
COMMON_CPUID_INDEX_80000001,
COMMON_CPUID_INDEX_D_ECX_1,
COMMON_CPUID_INDEX_80000007,
COMMON_CPUID_INDEX_80000008,
COMMON_CPUID_INDEX_7_ECX_1,
/* Keep the following line at the end. */
COMMON_CPUID_INDEX_MAX
};
struct cpuid_features
{
struct cpuid_registers cpuid;
struct cpuid_registers usable;
};
struct cpu_features
{
struct cpu_features_basic basic;
struct cpuid_features features[COMMON_CPUID_INDEX_MAX];
};
/* Get a pointer to the CPU features structure. */
extern const struct cpu_features *__x86_get_cpu_features
(unsigned int max) __attribute__ ((const));
Since all feature checks are done through macros, programs compiled with
a newer <sys/platform/x86.h> are compatible with the older glibc binaries
as long as the layout of struct cpu_features is identical. The features
array can be expanded with backward binary compatibility for both .o and
.so files. When COMMON_CPUID_INDEX_MAX is increased to support new
processor features, __x86_get_cpu_features in the older glibc binaries
returns NULL and HAS_CPU_FEATURE/CPU_FEATURE_USABLE return false on the
new processor feature. No new symbol version is neeeded.
Both CPU_FEATURE_USABLE and HAS_CPU_FEATURE are provided. HAS_CPU_FEATURE
can be used to identify processor features.
Note: Although GCC has __builtin_cpu_supports, it only supports a subset
of <sys/platform/x86.h> and it is equivalent to CPU_FEATURE_USABLE. It
doesn't support HAS_CPU_FEATURE.
2020-06-30 09:30:54 +08:00
|
|
|
|
* Add <sys/platform/x86.h> to provide query macros for x86 CPU features.
|
2020-07-14 21:29:56 +08:00
|
|
|
|
|
|
|
|
|
|
* Support for the RISC-V ISA running on Linux has been expanded to run on
|
|
|
|
|
|
32-bit hardware. This is supported for the following ISA and ABI pairs:
|
|
|
|
|
|
|
|
|
|
|
|
- rv32imac ilp32
|
|
|
|
|
|
- rv32imafdc ilp32
|
|
|
|
|
|
- rv32imafdc ilp32d
|
|
|
|
|
|
|
|
|
|
|
|
The 32-bit RISC-V port requires at least Linux 5.4, GCC 7.1 and binutils
|
|
|
|
|
|
2.28.

Introduce _FORTIFY_SOURCE=3
Introduce a new _FORTIFY_SOURCE level of 3 to enable additional
fortifications that may have a noticeable performance impact, allowing
more fortification coverage at the cost of some performance.
With llvm 9.0 or later, this will replace the use of
__builtin_object_size with __builtin_dynamic_object_size.
__builtin_dynamic_object_size
-----------------------------
__builtin_dynamic_object_size is an LLVM builtin that is similar to
__builtin_object_size. In addition to what __builtin_object_size
does, i.e. replace the builtin call with a constant object size,
__builtin_dynamic_object_size will replace the call site with an
expression that evaluates to the object size, thus expanding its
applicability. In practice, __builtin_dynamic_object_size evaluates
these expressions through malloc/calloc calls that it can associate
with the object being evaluated.
A simple motivating example is below; -D_FORTIFY_SOURCE=2 would miss
this and emit memcpy, but -D_FORTIFY_SOURCE=3 with the help of
__builtin_dynamic_object_size is able to emit __memcpy_chk with the
allocation size expression passed into the function:
void *copy_obj (const void *src, size_t alloc, size_t copysize)
{
void *obj = malloc (alloc);
memcpy (obj, src, copysize);
return obj;
}
Limitations
-----------
If the object was allocated elsewhere that the compiler cannot see, or
if it was allocated in the function with a function that the compiler
does not recognize as an allocator then __builtin_dynamic_object_size
also returns -1.
Further, the expression used to compute object size may be non-trivial
and may potentially incur a noticeable performance impact. These
fortifications are hence enabled at a new _FORTIFY_SOURCE level to
allow developers to make a choice on the tradeoff according to their
environment.
2020-12-30 14:24:00 +08:00
|
|
|
|
* A new fortification level _FORTIFY_SOURCE=3 is available. At this level,
|
|
|
|
|
|
glibc may use additional checks that may have an additional performance
|
|
|
|
|
|
overhead. At present these checks are available only on LLVM 9 and later.
|
|
|
|
|
|
The latest GCC available at this time (10.2) does not support this level of
|
|
|
|
|
|
fortification.

Deprecated and removed features, and other changes affecting compatibility:
|
|
|
|
|
|
|
2020-09-02 04:17:25 +08:00
|
|
|
|
* The mallinfo function is marked deprecated. Callers should call
|
|
|
|
|
|
mallinfo2 instead.
|
2020-08-05 11:41:43 +08:00
|
|
|
|
|
2020-10-07 22:40:23 +08:00
|
|
|
|
* When dlopen is used in statically linked programs, alternative library
|
|
|
|
|
|
implementations from HWCAP subdirectories are no longer loaded.
|
|
|
|
|
|
Instead, the default implementation is used.
|
|
|
|
|
|
|
2020-10-17 01:51:40 +08:00
|
|
|
|
* The deprecated <sys/vtimes.h> header and the function vtimes have been
|
|
|
|
|
|
removed. To support old binaries, the vtimes function continues to exist
|
|
|
|
|
|
as a compatibility symbol. Applications should use the getrlimit or
|
|
|
|
|
|
prlimit.
|
|
|
|
|
|
|
2020-11-25 22:51:51 +08:00
|
|
|
|
* Following a change in the tzdata 2018a release upstream, the zdump
|
|
|
|
|
|
program is now installed in the /usr/bin subdirectory. Previously,
|
|
|
|
|
|
the /usr/sbin subdirectory was used.
|
|
|
|
|
|
|
2020-11-30 22:53:59 +08:00
|
|
|
|
* On s390(x), the type float_t is now derived from the macro
|
|
|
|
|
|
__FLT_EVAL_METHOD__ that is defined by the compiler, instead of being
|
|
|
|
|
|
hardcoded to double. This does not affect the ABI of any libraries
|
|
|
|
|
|
that are part of the GNU C Library, but may affect the ABI of other
|
|
|
|
|
|
libraries that use this type in their interfaces. The new definition
|
|
|
|
|
|
improves consistency with compiler behavior in many scenarios.
|
|
|
|
|
|
|
2021-01-30 00:26:18 +08:00
|
|
|
|
* A future version of glibc will stop loading shared objects from the
|
|
|
|
|
|
"tls" subdirectories on the library search path, the subdirectory that
|
|
|
|
|
|
corresponds to the AT_PLATFORM system name, and also stop employing
|
|
|
|
|
|
the legacy AT_HWCAP search mechanism. Applications should switch to
|
|
|
|
|
|
the new glibc-hwcaps mechanism instead; if they do not do that, only
|
|
|
|
|
|
the baseline version (directly from the search path directory) will be
|
|
|
|
|
|
loaded.
|
|
|

Changes to build and runtime requirements:
|
|
|
|
|
|
|
2020-10-07 20:55:04 +08:00
|
|
|
|
* On Linux, the system administrator needs to configure /dev/pts with
|
|
|
|
|
|
the intended access modes for pseudo-terminals. glibc no longer
|
2023-05-20 21:37:47 +08:00
|
|
|
|
attempts to adjust permissions of terminal devices. The previous glibc
|
2020-10-07 20:55:04 +08:00
|
|
|
|
defaults ("tty" group, user read/write and group write) already
|
|
|
|
|
|
corresponded to what most systems used, so that grantpt did not
|
|
|
|
|
|
perform any adjustments.
|
|
|
|
|
|
|
|
|
|
|
|
* On Linux, the posix_openpt and getpt functions no longer attempt to
|
|
|
|
|
|
use legacy (BSD) pseudo-terminals and assume that if /dev/ptmx exists
|
|
|
|
|
|
(and pseudo-terminals are supported), a devpts file system is mounted
|
|
|
|
|
|
on /dev/pts. Current systems already meet these requirements.

Version 2.32
|
|
|
|
|
|
|
|
|
|
|
|
Major new features:
|
|
|
|
|
|
|
2020-07-08 20:41:23 +08:00
|
|
|
|
* Unicode 13.0.0 Support: Character encoding, character type info, and
|
|
|
|
|
|
transliteration tables are all updated to Unicode 13.0.0, using
|
2020-04-15 00:43:13 +08:00
|
|
|
|
generator scripts contributed by Mike FABIAN (Red Hat).
|
|
|
|
|
|
|
|
|
|
|
|
* New locale added: ckb_IQ (Kurdish/Sorani spoken in Iraq)
|
2020-02-01 19:38:55 +08:00
|
|
|
|
|
2017-11-21 04:46:17 +08:00
|
|
|
|
* Support for Synopsys ARC HS cores (ARCv2 ISA) running Linux has been
|
|
|
|
|
|
added. This port requires at least binutils-2.32, gcc-8.3 and Linux-5.1.
|
|
|
|
|
|
Three ABIs are supported:
|
|
|
|
|
|
|
|
|
|
|
|
- arc-linux-gnu
|
|
|
|
|
|
- arc-linux-gnuhf
|
|
|
|
|
|
- arceb-linux-gnu
|
|
|
|
|
|
|
2020-12-08 22:56:32 +08:00
|
|
|
|
The arc* ABIs are little-endian while arceb is big-endian. All ABIs use
|
2017-11-21 04:46:17 +08:00
|
|
|
|
64-bit time (y2038 safe) and 64-bit file offsets (LFS default).
|
|
|
|
|
|
|
2020-02-17 23:49:40 +08:00
|
|
|
|
* The GNU C Library now loads audit modules listed in the DT_AUDIT and
|
|
|
|
|
|
DT_DEPAUDIT dynamic section entries of the main executable.
|
|
|
|
|
|
|
2019-07-11 22:48:28 +08:00
|
|
|
|
* powerpc64le supports IEEE128 long double libm/libc redirects when
|
2020-12-08 22:56:32 +08:00
|
|
|
|
using -mabi=ieeelongdouble to compile C code on supported GCC
|
2019-07-11 22:48:28 +08:00
|
|
|
|
toolchains. It is recommended to use GCC 8 or newer when testing
|
|
|
|
|
|
this option.
|
|
|
|
|
|
|
2020-05-20 23:40:34 +08:00
|
|
|
|
* To help detect buffer overflows and other out-of-bounds accesses
|
|
|
|
|
|
several APIs have been annotated with GCC 'access' attribute. This
|
|
|
|
|
|
should help GCC 10 issue better warnings.
|
|
|
|
|
|
|
2020-12-08 22:56:32 +08:00
|
|
|
|
* On Linux, functions pthread_attr_setsigmask_np and
|
2020-06-02 16:34:55 +08:00
|
|
|
|
pthread_attr_getsigmask_np have been added. They allow applications
|
|
|
|
|
|
to specify the signal mask of a thread created with pthread_create.
|
|
|
|
|
|
|
2020-05-20 21:40:35 +08:00
|
|
|
|
* The GNU C Library now provides the header file <sys/single_threaded.h>
|
|
|
|
|
|
which declares the variable __libc_single_threaded. Applications are
|
|
|
|
|
|
encouraged to use this variable for single-thread optimizations,
|
|
|
|
|
|
instead of weak references to symbols historically defined in
|
|
|
|
|
|
libpthread.
|
|
|
|
|
|
|
2020-05-19 04:05:05 +08:00
|
|
|
|
* The functions sigabbrev_np and sigdescr_np have been added. The
|
2020-12-08 22:56:32 +08:00
|
|
|
|
sigabbrev_np function returns the abbreviated signal name (e.g. "HUP" for
|
|
|
|
|
|
SIGHUP) while sigdescr_np returns a string describing the signal number
|
|
|
|
|
|
(e.g "Hangup" for SIGHUP). Different than strsignal, sigdescr_np does not
|
2020-05-19 04:05:05 +08:00
|
|
|
|
attempt to translate the return description, both functions return
|
|
|
|
|
|
NULL for an invalid signal number.
|
|
|
|
|
|
|
|
|
|
|
|
They should be used instead of sys_siglist or sys_sigabbrev and they
|
|
|
|
|
|
are both thread and async-signal safe. These functions are GNU extensions.
|
|
|
|
|
|
|
2020-05-19 04:41:25 +08:00
|
|
|
|
* The functions strerrorname_np and strerrordesc_np have been added. The
|
2020-12-08 22:56:32 +08:00
|
|
|
|
strerroname_np function returns error number name (e.g. "EINVAL" for EINVAL)
|
|
|
|
|
|
while strerrordesc_np returns a string describing the error number
|
2020-05-19 04:41:25 +08:00
|
|
|
|
(e.g "Invalid argument" for EINVAL). Different than strerror,
|
|
|
|
|
|
strerrordesc_np does not attempt to translate the return description, both
|
|
|
|
|
|
functions return NULL for an invalid error number.
|
|
|
|
|
|
|
|
|
|
|
|
They should be used instead of sys_errlist and sys_nerr, both are
|
|
|
|
|
|
thread and async-signal safe. These functions are GNU extensions.
|
|
|
|
|
|
|
2020-06-12 01:19:40 +08:00
|
|
|
|
* AArch64 now supports standard branch protection security hardening
|
|
|
|
|
|
in glibc when it is built with a GCC that is configured with
|
2020-07-29 15:27:27 +08:00
|
|
|
|
--enable-standard-branch-protection (or if -mbranch-protection=standard
|
|
|
|
|
|
flag is passed when building both GCC target libraries and glibc,
|
|
|
|
|
|
in either case a custom GCC is needed). This includes branch target
|
2020-06-12 01:19:40 +08:00
|
|
|
|
identification (BTI) and pointer authentication for return addresses
|
|
|
|
|
|
(PAC-RET). They require armv8.5-a and armv8.3-a architecture
|
|
|
|
|
|
extensions respectively for the protection to be effective,
|
|
|
|
|
|
otherwise the used instructions are nops. User code can use PAC-RET
|
|
|
|
|
|
without libc support, but BTI requires a libc that is built with BTI
|
|
|
|
|
|
support, otherwise runtime objects linked into user code will not be
|
|
|
|
|
|
BTI compatible.
|
|
|
|
|
|
|
2020-02-01 19:38:55 +08:00
|
|
|
|
Deprecated and removed features, and other changes affecting compatibility:
|
|
|
|
|
|
|
2020-07-14 01:36:35 +08:00
|
|
|
|
* Remove configure option --enable-obsolete-rpc. Sun RPC is removed
|
|
|
|
|
|
from glibc. This includes the rpcgen program, librpcsvc, and the Sun
|
|
|
|
|
|
RPC header files. Backward compatibility for old programs is kept
|
|
|
|
|
|
only for architectures and ABIs that have been added in or before
|
|
|
|
|
|
glibc 2.31. New programs need to use TI-RPC
|
|
|
|
|
|
<http://git.linux-nfs.org/?p=steved/libtirpc.git;a=summary> and
|
|
|
|
|
|
rpcsvc-proto <https://github.com/thkukuk/rpcsvc-proto>.
|
|
|
|
|
|
|
2020-07-08 19:06:55 +08:00
|
|
|
|
* Remove configure option --enable-obsolete-nsl. libnsl is only built
|
|
|
|
|
|
as shared library for backward compatibility and the NSS modules "nis"
|
|
|
|
|
|
and "nisplus" are not built at all and libnsl's headers aren't
|
|
|
|
|
|
installed. This compatibility is kept only for architectures and ABIs
|
|
|
|
|
|
that have been added in or before version 2.28. Replacement
|
|
|
|
|
|
implementations based on TI-RPC, which additionally support IPv6, are
|
|
|
|
|
|
available from <https://github.com/thkukuk/>. This change does not
|
2020-12-08 22:56:32 +08:00
|
|
|
|
affect the "compat" NSS module, which does not depend on libnsl
|
2020-07-08 19:06:55 +08:00
|
|
|
|
since 2.27 and thus can be used without NIS.
|
|
|
|
|
|
|
2020-04-15 23:17:32 +08:00
|
|
|
|
* The deprecated <sys/sysctl.h> header and the sysctl function have been
|
|
|
|
|
|
removed. To support old binaries, the sysctl function continues to
|
|
|
|
|
|
exist as a compatibility symbol (on those architectures which had it),
|
|
|
|
|
|
but always fails with ENOSYS. This reflects the removal of the system
|
|
|
|
|
|
call from all architectures, starting with Linux 5.5.
|
2020-02-01 19:38:55 +08:00
|
|
|
|
|
2020-04-28 18:10:32 +08:00
|
|
|
|
* The sstk function is no longer available to newly linked binaries.
|
|
|
|
|
|
Its implementation always returned with a failure, and the function
|
|
|
|
|
|
was not declared in any header file.
|
|

* Both strerror and strerror_l now share the same internal buffer in the

or contents might be overwritten on subsequent calls in the same thread or

if the thread is terminated. It makes strerror MT-safe.

* Using weak references to libpthread functions such as pthread_create
|
|
|
|
|
|
or pthread_key_create to detect the singled-threaded nature of a

|
|
|

|
program is an obsolescent feature. Future versions of glibc will
|
|
|
|
|
|
define pthread_create within libc.so.6 itself, so such checks will
|
|
|
|
|
|
always flag the program as multi-threaded. Applications should check
|
|
|
|
|
|
the __libc_single_threaded variable declared in
|
|
|
|
|
|
<sys/single_threaded.h> instead.

|
secure RPC). The contents of the /etc/publickey file will be ignored,
|
|
|
|
|
|
regardless of the settings in /etc/nsswitch.conf. (This method of
|
|
|
|
|
|
storing RPC keys only supported the obsolete and insecure AUTH_DES
|
|
|
|
|

flavor of secure RPC.)

* The __morecore and __after_morecore_hook malloc hooks and the default
|
|
|
|
|
|
implementation __default_morecore have been deprecated. Applications
|
|
|
|
|
|
should use malloc interposition to change malloc behavior, and mmap to
|
|
|
|
|
|
allocate anonymous memory. A future version of glibc may require that
|
|
|
|
|
|
applications which use the malloc hooks must preload a special shared
|
|
|
|
|
|
object, to enable the hooks.

switch to other approaches for networked account databases, such as

powerpc64le: raise GCC requirement to 7.4 for long double transition
Add compiler feature tests to ensure we can build ieee128 long double.
These test for -mabi=ieeelongdouble, -mno-gnu-attribute, and -Wno-psabi.
Likewise, verify some compiler bugs have been addressed. These aren't
helpful for building glibc, but may cause test failures when testing
the new long double. See notes below from Raji.
On powerpc64le, some older compiler versions give error for the function
signbit() for 128-bit floating point types. This is fixed by PR83862
in gcc 8.0 and backported to gcc6 and gcc7. This patch adds a test
to check compiler version to avoid compiler errors during make check.
Likewise, test for -mno-gnu-attribute support which was
On powerpc64le, a few files are built on IEEE long double mode
(-mabi=ieeelongdouble), whereas most are built on IBM long double mode
(-mabi=ibmlongdouble, the default for -mlong-double-128). Since binutils
2.31, linking object files with different long double modes causes
errors similar to:
ld: libc_pic.a(s_isinfl.os) uses IBM long double,
libc_pic.a(ieee128-qefgcvt.os) uses IEEE long double.
collect2: error: ld returned 1 exit status
make[2]: *** [../Makerules:649: libc_pic.os] Error 1
The warnings are fair and correct, but in order for glibc to have
support for both long double modes on powerpc64le, they have to be
ignored. This can be accomplished with the use of -mno-gnu-attribute
option when building the few files that require IEEE long double mode.
However, -mno-gnu-attribute is not available in GCC 6, the minimum
version required to build glibc, so this patch adds a test for this
feature in powerpc64le builds, and fails early if it's not available.

Add tgmath.h macros for narrowing functions.
When adding some of the TS 18661 narrowing functions for glibc 2.28, I
deferred adding corresponding <tgmath.h> support because of unresolved
questions about the specification for those type-generic macros,
especially in relation to _FloatN and _FloatNx types.
Those issues are now clarified in the response to Clarification
Request 13 to TS 18661-3, and this patch adds the deferred tgmath.h
support. As with other tgmath.h macros, there are fairly
straightforward implementations based on __builtin_tgmath for GCC 8
and later, which result in exactly the right function being called in
each case, and more complicated implementations for GCC 7 and earlier,
which generally result in a function being called whose arguments have
the right format (i.e. an alias for the right function), but which
might not be exactly the function name specified by TS 18661.
In one case with older compilers (f32x* macros, where the type
_Float64x exists and all the arguments have type _Float32 or
_Float32x), there is a further relaxation and the function called may
have arguments narrower than the one specified by the TS, but still
wide enough to represent the arguments exactly, so the result of the
call is unchanged (as this does not affect any case where rounding of
integer arguments might be involved). With GCC 6 or before this is
inherently unavoidable (but still harmless and not detectable by how
the compiled program behaves, unless it redefines the functions in
question like the testcases do) because _Float32x and _Float64 are
both typedefs for double in that case but the specified semantics
result in different functions, with different argument formats, being
called for those two argument types.
Tests for the new macros are handled through gen-tgmath-tests.py,
which deals with the special-case handling for older GCC.
Tested as follows: with the full glibc testsuite on x86_64 and x86
(with GCC 6, 7 and 8); with the math/ tests on aarch64 and arm (with
GCC 6, 7 and 8); with build-many-glibcs.py (with GCC 6, 7 and 9).

Make totalorder and totalordermag functions take pointer arguments.
The resolution of C floating-point Clarification Request 25
<http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2397.htm#dr_25> is
that the totalorder and totalordermag functions should take pointer
arguments, and this has been adopted in C2X (with const added; note
that the integration of this change into C2X is present in the C
standard git repository but postdates the most recent public PDF
draft).
This patch updates glibc accordingly. As a defect resolution, the API
is changed unconditionally rather than supporting any sort of TS
18661-1 mode for compilation with the old version of the API. There
are compat symbols for existing binaries that pass floating-point
arguments directly. As a consequence of changing to pointer
arguments, there are no longer type-generic macros in tgmath.h for
these functions.
Because of the fairly complicated logic for creating libm function
aliases and determining the set of aliases to create in a given glibc
configuration, rather than duplicating all that in individual source
files to create the versioned and compat symbols, the source files for
the various versions of totalorder functions are set up to redefine
weak_alias before using libm_alias_* macros to create the symbols
required. In turn, this requires creating a separate alias for each
symbol version pointing to the same implementation (see binutils bug
<https://sourceware.org/bugzilla/show_bug.cgi?id=23840>), which is
done automatically using __COUNTER__. (As I noted in
<https://sourceware.org/ml/libc-alpha/2018-10/msg00631.html>, it might
well make sense for glibc's symbol versioning macros to do that alias
creation with __COUNTER__ themselves, which would somewhat simplify
the logic in the totalorder source files.)
It is of course desirable to test the compat symbols. I did this with
the generic libm-test machinery, but didn't wish to duplicate the
actual tables of test inputs and outputs, and thought it risky to
attempt to have a single object file refer to both default and compat
versions of the same function in order to test them together. Thus, I
created libm-test-compat_totalorder.inc and
libm-test-compat_totalordermag.inc which include the generated .c
files (with the processed version of those tables of inputs) from the
non-compat tests, and added appropriate dependencies. I think this
provides sufficient test coverage for the compat symbols without also
needing to make the special ldbl-96 and ldbl-128ibm tests (of
peculiarities relating to the representations of those formats that
can't be covered in the generic tests) run for the compat symbols.
Tests of compat symbols need to be internal tests, meaning _ISOMAC is
not defined. Making some libm-test tests into internal tests showed
up two other issues. GCC diagnoses duplicate macro definitions of
__STDC_* macros, including __STDC_WANT_IEC_60559_TYPES_EXT__; I added
an appropriate conditional and filed
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91451> for this issue.
On ia64, include/setjmp.h ends up getting included indirectly from
libm-symbols.h, resulting in conflicting definitions of the STR macro
(also defined in libm-test-driver.c); I renamed the macros in
include/setjmp.h. (It's arguable that we should have common internal
headers used everywhere for stringizing and concatenation macros.)

binaries, and its declaration has been removed from <time.h>.
|

|
|
Programs that set the system time should use clock_settime instead.

|
|
|
* We plan to remove the obsolete function ftime, and the header <sys/timeb.h>,
|
|
|
|
|
|
in a future version of glibc. In this release, the header still exists
|
|
|
|
|
|
but calling ftime will cause a compiler warning. All programs should use

gettimeofday or clock_gettime instead.

* The gettimeofday function no longer reports information about a
|
|
|
|
|
|
system-wide time zone. This 4.2-BSD-era feature has been deprecated for
|
|
|
|
|
|
many years, as it cannot handle the full complexity of the world's
|
|
|
|
|
|
timezones, but hitherto we have supported it on a best-effort basis.
|
|
|
|
|
|
Changes required to support 64-bit time_t on 32-bit architectures have
|
|
|
|
|
|
made this no longer practical.
|
|
|
|
|
|
|
|
|
|
|
|
As of this release, callers of gettimeofday with a non-null 'tzp' argument
|
|
|
|
|
|
should expect to receive a 'struct timezone' whose tz_minuteswest and
|
|
|
|
|
|
tz_dsttime fields are zero. (For efficiency reasons, this does not always
|
|
|
|
|
|
happen on a few Linux-based ports. This will be corrected in a future
|
|
|
|
|
|
release.)
|
|
|
|
|
|
|
|
|
|
|
|
All callers should supply a null pointer for the 'tzp' argument to
|
|
|
|
|
|
gettimeofday. For accurate information about the time zone associated
|
|
|
|
|
|
with the current time, use the localtime function.
|
|
|
|
|
|
|
|
|
|
|
|
gettimeofday itself is obsolescent according to POSIX. We have no plans
|
|
|
|
|
|
to remove access to this function, but portable programs should consider
|
|
|
|
|
|
using clock_gettime instead.

Use clock_settime to implement settimeofday.
Unconditionally, on all ports, use clock_settime to implement
settimeofday. Remove sysdeps/unix/clock_settime.c, which implemented
clock_settime by calling settimeofday; new OS ports must henceforth
provide a real implementation of clock_settime.
Hurd had a real implementation of settimeofday but not of
clock_settime; this patch converts it into an implementation of
clock_settime. It only supports CLOCK_REALTIME and microsecond
resolution; Hurd/Mach does not appear to have any support for
finer-resolution clocks.
The vestigial "set time zone" feature of settimeofday complicates the
generic settimeofday implementation a little. The only remaining uses
of this feature that aren't just bugs, are using it to inform the
Linux kernel of the offset between the hardware clock and UTC, on
systems where the hardware clock doesn't run in UTC (usually because
of dual-booting with Windows). There currently isn't any other way to
do this. However, the callers that do this call settimeofday with
_only_ the timezone argument non-NULL. Therefore, glibc's new
behavior is: callers of settimeofday must supply one and only one of
the two arguments. If both arguments are non-NULL, or both arguments
are NULL, the call fails and sets errno to EINVAL.
When only the timeval argument is supplied, settimeofday calls
__clock_settime(CLOCK_REALTIME), same as stime.
When only the timezone argument is supplied, settimeofday calls a new
internal function called __settimezone. On Linux, only, this function
will pass the timezone structure to the settimeofday system call. On
all other operating systems, and on Linux architectures that don't
define __NR_settimeofday, __settimezone is a stub that always sets
errno to ENOSYS and returns -1.
The settimeoday syscall is enabled on Linux by the flag
COMPAT_32BIT_TIME, which is an option to either 32-bits ABIs or COMPAT
builds (defined usually by 64-bit kernels that want to support 32-bit
ABIs, such as x86). The idea to future 64-bit time_t only ABIs
is to not provide settimeofday syscall.
The same semantics are implemented for Linux/Alpha's GLIBC_2.0 compat
symbol for settimeofday.
There are no longer any internal callers of __settimeofday, so the
internal prototype is removed.
Checked on x86_64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu,
powerpc64-linux-gnu, powerpc-linux-gnu, and aarch64-linux-gnu.

|
* The settimeofday function can still be used to set a system-wide time
|
|
|
|
|
|
zone when the operating system supports it. This is because the Linux
|
|
|
|
|
|
kernel reused the API, on some architectures, to describe a system-wide
|
|
|
|
|
|
time-zone-like offset between the software clock maintained by the kernel,
|
|
|
|
|
|
and the "RTC" clock that keeps time when the system is shut down.
|
|
|
|
|
|
|
|
|
|
|
|
However, to reduce the odds of this offset being set by accident,
|
|
|
|
|
|
settimeofday can no longer be used to set the time and the offset
|
|
|
|
|
|
simultaneously. If both of its two arguments are non-null, the call
|
|
|
|
|
|
will fail (setting errno to EINVAL).
|
|
|
|
|
|
|
|
|
|
|
|
Callers attempting to set this offset should also be prepared for the call
|
|
|
|
|
|
to fail and set errno to ENOSYS; this already happens on the Hurd and on
|
|
|
|
|
|
some Linux architectures. The Linux kernel maintainers are discussing a
|
|
|
|
|
|
more principled replacement for the reused API. After a replacement
|
|
|
|
|
|
becomes available, we will change settimeofday to fail with ENOSYS on all
|
|
|
|
|
|
platforms when its 'tzp' argument is not a null pointer.

|

|

|
|
|
|
settimeofday itself is obsolescent according to POSIX. Programs that set
|
|
|
|
|
|
the system time should use clock_settime and/or the adjtime family of
|
|
|
|
|
|
functions instead. We may cease to make settimeofday available to newly
|
|
|
|
|
|
linked binaries after there is a replacement for Linux's time-zone-like
|
|
|
|
|
|
offset API.
|
Use clock_settime to implement settimeofday.
Unconditionally, on all ports, use clock_settime to implement
settimeofday. Remove sysdeps/unix/clock_settime.c, which implemented
clock_settime by calling settimeofday; new OS ports must henceforth
provide a real implementation of clock_settime.
Hurd had a real implementation of settimeofday but not of
clock_settime; this patch converts it into an implementation of
clock_settime. It only supports CLOCK_REALTIME and microsecond
resolution; Hurd/Mach does not appear to have any support for
finer-resolution clocks.
The vestigial "set time zone" feature of settimeofday complicates the
generic settimeofday implementation a little. The only remaining uses
of this feature that aren't just bugs, are using it to inform the
Linux kernel of the offset between the hardware clock and UTC, on
systems where the hardware clock doesn't run in UTC (usually because
of dual-booting with Windows). There currently isn't any other way to
do this. However, the callers that do this call settimeofday with
_only_ the timezone argument non-NULL. Therefore, glibc's new
behavior is: callers of settimeofday must supply one and only one of
the two arguments. If both arguments are non-NULL, or both arguments
are NULL, the call fails and sets errno to EINVAL.
When only the timeval argument is supplied, settimeofday calls
__clock_settime(CLOCK_REALTIME), same as stime.
When only the timezone argument is supplied, settimeofday calls a new
internal function called __settimezone. On Linux, only, this function
will pass the timezone structure to the settimeofday system call. On
all other operating systems, and on Linux architectures that don't

errno to ENOSYS and returns -1.

* SPARC ISA v7 is no longer supported. v8 is still supported, but only if
|

|

|
|
the optional CAS instruction is implemented (for instance, LEON processors
|
|
|
|
|
|
are still supported, but SuperSPARC processors are not).
|
Consolidate and deprecate ftime
ftime is an obsolete variation on gettimeofday, offering only
millisecond time resolution; it was probably a system call in ooold
versions of BSD Unix. For historic reasons, we had three
implementations of it. These are all consolidated into time/ftime.c,
and then the function is deprecated.
For some reason, the implementation of ftime in terms of gettimeofday
was rounding rather than truncating microseconds to milliseconds. In
all the other places where we use a higher-resolution time function to
implement a lower-resolution one, we truncate. ftime is changed to
match, just for tidiness' sake.
Like gettimeofday, ftime tries to report the time zone, and using that
information is always a bug. This patch dummies out the reported
timezone information; the timezone and dstflag fields of the
returned "struct timeb" will always be zero.

* If a lazy binding failure happens during dlopen, during the execution of

an ELF constructor, the process is now terminated. Previously, the

* For MIPS hard-float ABIs, the GNU C Library will be configured to need an
|
|
|
|
|
|
executable stack unless explicitly configured at build time to require
|
|
|
|
|
|
minimum kernel version 4.8 or newer. This is because executing
|
|
|
|
|
|
floating-point branches on a non-executable stack on Linux kernels prior to
|
|
|
|
|
|
4.8 can lead to application crashes for some MIPS configurations. While
|
|
|
|
|
|
currently PT_GNU_STACK is not widely used on MIPS, future releases of GCC are
|
|
|
|
|
|
expected to enable non-executable stack by default with PT_GNU_STACK by
|
|
|
|
|
|
default and is thus likely to trigger a crash on older kernels.
|
|
|
|
|
|
|
|
|
|
|
|
The GNU C Library can be built with --enable-kernel=4.8.0 in order to keep a

non-executable stack while dropping support for older kernels.

|
* Memory allocation functions malloc, calloc, realloc, reallocarray, valloc,
|
|
|
|
|
|
pvalloc, memalign, and posix_memalign fail now with total object size
|
|
|
|
|
|
larger than PTRDIFF_MAX. This is to avoid potential undefined behavior with
|
|
|
|
|
|
pointer subtraction within the allocated object, where results might
|
|
|
|
|
|
overflow the ptrdiff_t type.

versioned symbols whose implementation has moved to a different soname

since the object has been linked. The old error message, symbol

FUNCTION-NAME, version SYMBOL-VERSION not defined in file DSO-NAME with

* Add new POSIX-proposed pthread_cond_clockwait, pthread_mutex_clocklock,
|
|
|
|
|
|
pthread_rwlock_clockrdlock, pthread_rwlock_clockwrlock and sem_clockwait
|
|
|
|
|
|
functions. These behave similarly to their "timed" equivalents, but also
|
|
|
|
|
|
accept a clockid_t parameter to determine which clock their timeout should
|
|
|
|
|
|
be measured against. All functions allow waiting against CLOCK_MONOTONIC
|
|
|
|
|
|
and CLOCK_REALTIME. The decision of which clock to be used is made at the
|
|
|
|
|
|
time of the wait (unlike with pthread_condattr_setclock, which requires
|
|
|
|
|
|
the clock choice at initialization time).

* On AArch64 the GNU IFUNC resolver call ABI changed: old resolvers still
|
|
|

work, new resolvers can use a second argument which can be extended in
|
|
|
|
|
|
the future, currently it contains the AT_HWCAP2 value.

|
* The copy_file_range function fails with ENOSYS if the kernel does not
|
|
|
|
|
|
support the system call of the same name. Previously, user space
|
|
|
|
|
|
emulation was performed, but its behavior did not match the kernel
|
|
|
|
|
|
behavior, which was deemed too confusing. Applications which use the
|
2019-07-09 05:10:52 +08:00
|
|
|
|
copy_file_range function can no longer rely on glibc to provide a fallback
|
|
|
|
|
|
on kernels that do not support the copy_file_range system call, and if
|
|
|
|
|
|
this function returns ENOSYS, they will need to use their own fallback.
|
|
|
|
|
|
Support for copy_file_range for most architectures was added in version
|
|
|
|
|
|
4.5 of the mainline Linux kernel.

rt: Turn forwards from librt to libc into compat symbols [BZ #24194]
As the result of commit 6e6249d0b461b952d0f544792372663feb6d792a
("BZ#14743: Move clock_* symbols from librt to libc."), in glibc 2.17,
clock_gettime, clock_getres, clock_settime, clock_getcpuclockid,
clock_nanosleep were added to libc, and the file rt/clock-compat.c
was added with forwarders to the actual implementations in libc.
These forwarders were wrapped in
#if SHLIB_COMPAT (librt, GLIBC_2_2, GLIBC_2_17)
so that they are not present for newer architectures (such as
powerpc64le) with a 2.17 or later ABI baseline. But the forwarders
were not marked as compatibility symbols. As a result, on older
architectures, historic configure checks such as
AC_CHECK_LIB(rt, clock_gettime)
still cause linking against librt, even though this is completely
unnecessary. It also creates a needless porting hazard because
architectures behave differently when it comes to symbol availability.

|
|
|
|
* The functions clock_gettime, clock_getres, clock_settime,
|
|
|
|
|
|
clock_getcpuclockid, clock_nanosleep were removed from the librt library
|
|
|
|
|
|
for new applications (on architectures which had them). Instead, the
|
|
|
|
|
|
definitions in libc will be used automatically, which have been available
|
|
|
|
|
|
since glibc 2.17.

* Support for the PowerPC SPE ISA extension (powerpc-*-*gnuspe*
|

2019-05-29 22:53:09 +08:00
|
|
|
|
* On 32-bit Arm, support for the port-based I/O emulation and the <sys/io.h>
|
|

|
|
|
|
|
|
|
2019-06-12 20:32:08 +08:00
|
|
|
|
* The Linux-specific <sys/sysctl.h> header and the sysctl function have been
|
|
|
|
|
|
deprecated and will be removed from a future version of glibc.
|
|
|
|

CVE-2019-7309: x86-64 memcmp used signed Jcc instructions to check
|
|
|
|
|
|
size. For x86-64, memcmp on an object size larger than SSIZE_MAX
|
|
|
|
|
|
has undefined behavior. On x32, the size_t argument may be passed
|
|
|
|
|
|
in the lower 32 bits of the 64-bit RDX register with non-zero upper
|
|
|
|
|
|
32 bits. When it happened with the sign bit of RDX register set,
|
|
|
|
|
|
memcmp gave the wrong result since it treated the size argument as
|
|
|
|
|
|
zero. Reported by H.J. Lu.

|
|
|
|
|
Major new features:

|
|
|
|
|
|
2018-12-08 01:17:37 +08:00
|
|
|
|
* The getcpu wrapper function has been added, which returns the currently
|
|
|
|
|
|
used CPU and NUMA node. This function is Linux-specific.
|
|
|
|
|
|
|
2018-07-26 22:14:55 +08:00
|
|
|
|
* A new convenience target has been added for distribution maintainers
|
|
|
|
|
|
to build and install all locales as directories with files. The new
|
|
|
|
|
|
target is run by issuing the following command in your build tree:
|
|
|
|
|
|
'make localedata/install-locale-files', with an optional DESTDIR
|
|
|
|
|
|
to set the install root if you wish to install into a non-default
|
|
|
|
|
|
configured location.

powerpc: Only enable TLE with PPC_FEATURE2_HTM_NOSC
Linux from 3.9 through 4.2 does not abort HTM transaction on syscalls,
instead it suspend and resume it when leaving the kernel. The
side-effects of the syscall will always remain visible, even if the
transaction is aborted. This is an issue when transaction is used along
with futex syscall, on pthread_cond_wait for instance, where the futex
call might succeed but the transaction is rolled back leading the
pthread_cond object in an inconsistent state.
Glibc used to prevent it by always aborting a transaction before issuing
a syscall. Linux 4.2 also decided to abort active transaction in
syscalls which makes the glibc workaround superfluous. Worse, glibc
transaction abortion leads to a performance issue on recent kernels
where the HTM state is saved/restore lazily (v4.9). By aborting a
transaction on every syscalls, regardless whether a transaction has being
initiated before, GLIBS makes the kernel always save/restore HTM state
(it can not even lazily disable it after a certain number of syscall
iterations).
Because of this shortcoming, Transactional Lock Elision is just enabled
when it has been explicitly set (either by tunables of by a configure
switch) and if kernel aborts HTM transactions on syscalls
(PPC_FEATURE2_HTM_NOSC). It is reported that using simple benchmark [1],
the context-switch is about 5% faster by not issuing a tabort in every
syscall in newer kernels.
Checked on powerpc64le-linux-gnu with 4.4.0 kernel (Ubuntu 16.04).
* NEWS: Add note about new TLE support on powerpc64le.
* sysdeps/powerpc/nptl/tcb-offsets.sym (TM_CAPABLE): Remove.
* sysdeps/powerpc/nptl/tls.h (tcbhead_t): Rename tm_capable to

|
* For powercp64le ABI, Transactional Lock Elision is now enabled iff kernel
|
|
|
|
|
|
indicates that it will abort the transaction prior to entering the kernel
|
|
|
|
|
|
(PPC_FEATURE2_HTM_NOSC on hwcap2). On older kernels the transaction is
|
|
|
|
|
|
suspended, and this caused some undefined side-effects issues by aborting
|
|
|
|
|
|
transactions manually. Glibc avoided it by abort transactions manually on
|
|
|
|
|
|
each syscall, but it lead to performance issues on newer kernels where the
|
|
|
|
|
|
HTM state is saved and restore lazily (the state being saved even when the
|
|
|
|
|
|
process actually does not use HTM).

|
* The functions posix_spawn_file_actions_addchdir_np and
|
|
|
|
|
|
posix_spawn_file_actions_addfchdir_np have been added, enabling
|
|
|
|
|
|
posix_spawn and posix_spawnp to run the new process in a different
|
|
|
|
|
|
directory. These functions are GNU extensions. The function
|
|
|
|
|
|
posix_spawn_file_actions_addchdir_np is similar to the Solaris function
|
|
|
|
|
|
of the same name.

* The popen and system do not run atfork handlers anymore (BZ#17490).
|
|
|
|
|
|
Although it is a possible POSIX violation, the POSIX rationale in
|
|
|
|
|
|
pthread_atfork documentation regarding atfork handlers is to handle
|
2018-12-29 04:15:41 +08:00
|
|
|
|
inconsistent mutex state after a fork call in a multi-threaded process.
|
2018-09-12 21:32:05 +08:00

In both popen and system there is no direct access to user-defined mutexes.

* Support for the C-SKY ABIV2 running on Linux has been added. This port
|
|
|

requires at least binutils-2.32, gcc-9.0, and linux-4.20. Two ABIs are
|
|
|
|

supported:
|

* strftime's default formatting of a locale's alternative year (%Ey)
|
|
|
|
|
|
has been changed to zero-pad the year to a minimum of two digits,
|
|
|
|
|
|
like "%y". This improves the display of Japanese era years during
|
|
|
|
|
|
the first nine years of a new era, and is expected to be harmless
|
|
|
|
|
|
for all other locales (only Japanese locales regularly have
|
|
|
|
|
|
alternative year numbers less than 10). Zero-padding can be
|
|
|
|
|
|
overridden with the '_' or '-' flags (which are GNU extensions).
|
|
|
|
|
|
|
2019-01-24 22:04:12 +08:00
|
|
|
|
* As a GNU extension, the '_' and '-' flags can now be applied to
|
|
|
|
|
|
"%EY" to control how the year number is formatted; they have the
|
|
|
|
|
|
same effect that they would on "%Ey".

Fix sys/procfs.h pr_uid, pr_gid type (bug 23649).
As noted in
<https://sourceware.org/ml/libc-alpha/2018-09/msg00178.html>, glibc's
sys/procfs.h headers for microblaze, mips (n64), nios2 and riscv have
incorrect types for the pr_uid and pr_gid members of struct
elf_prpsinfo (as does the generic Linux version, but nothing uses
that).
This patch fixes those headers to use unsigned int. The generic Linux
version is also fixed, but I do *not* recommend making new
architectures use it yet. Rather, I think it should be reworked to
look more like a copy of the AArch64 version, but with a new
<bits/procfs.h> header included to provide register set definitions;
<bits/procfs.h> would then be architecture-specific while many
architectures could use the generic <sys/procfs.h>. This fix is
deliberately separate from any reworking to use a generic header more,
since it's possible there could be uses for backporting this fix but
not for backporting a subsequent cleanup.
Tested with build-many-glibcs.py. This of course doesn't provide much
validation of the structure layout; if the Linux kernel is fixed so
that "#include <linux/elfcore.h>" actually compiles with the headers
from "make headers_install" (and if the layout in both headers is
meant to be the same, whatever ABI we are building for), I have a test
that can be added to glibc to check the layout against that from the
Linux kernel.
[BZ #23649]
* sysdeps/unix/sysv/linux/microblaze/sys/procfs.h (struct
elf_prpsinfo): Use unsigned int for pr_uid and pr_gid.
* sysdeps/unix/sysv/linux/mips/sys/procfs.h (struct elf_prpsinfo):
Likewise.
* sysdeps/unix/sysv/linux/nios2/sys/procfs.h (struct

|
|
|
* The type of the pr_uid and pr_gid members of struct elf_prpsinfo, defined
|
|
|
|
|
|
in <sys/procfs.h>, has been corrected to match the type actually used by
|
|
|
|
|
|
the Linux kernel. This affects the size and layout of that structure on
|
|
|
|
|

MicroBlaze, MIPS (n64 ABI only), Nios II and RISC-V.

|
struct elf_prstatus, and the pr_flag member of struct elf_prpsinfo,
|
|
|
|
|
|
defined in <sys/procfs.h>, has been corrected to match the type actually

Use C99-compliant scanf under _GNU_SOURCE with modern compilers.
The only difference between noncompliant and C99-compliant scanf is
that the former accepts the archaic GNU extension '%as' (also %aS and
%a[...]) meaning to allocate space for the input string with malloc.
This extension conflicts with C99's use of %a as a format _type_
meaning to read a floating-point number; POSIX.1-2008 standardized
equivalent functionality using the modifier letter 'm' instead (%ms,
%mS, %m[...]).
The extension was already disabled in most conformance modes:
specifically, any mode that doesn't involve _GNU_SOURCE and _does_
involve either strict conformance to C99 or loose conformance to both
C99 and POSIX.1-2001 would get the C99-compliant scanf. With
compilers new enough to use -std=gnu11 instead of -std=gnu89, or
equivalent, that includes the default mode.
With this patch, we now provide C99-compliant scanf in all
configurations except when _GNU_SOURCE is defined *and*
__STDC_VERSION__ or __cplusplus (whichever is relevant) indicates
C89/C++98. This leaves the old scanf available under e.g. -std=c89
-D_GNU_SOURCE, but removes it from e.g. -std=gnu11 -D_GNU_SOURCE (it
was already not present under -std=gnu11 without -D_GNU_SOURCE) and
from -std=gnu89 without -D_GNU_SOURCE.
There needs to be an internal override so we can compile the
noncompliant scanf itself. This is the same problem we had when we
removed 'gets' from _GNU_SOURCE and it's dealt with the same way:
there's a new __GLIBC_USE symbol, DEPRECATED_SCANF, which defaults to
off under the appropriate conditions for external code, but can be
overridden by individual files within stdio.
We also run into problems with PLT bypass for internal uses of sscanf,
because libc_hidden_proto uses __REDIRECT and so does the logic in
stdio.h for choosing which implementation of scanf to use; __REDIRECT
isn't transitive, so include/stdio.h needs to bridge the gap with a
macro. As far as I can tell, sscanf is the only function in this
family that's internally called by unrelated code.
Finally, there are several tests in stdio-common that use the
extension. bug21.c is a regression test for a crash; it still
exercises the relevant code when changed to use %ms instead of %as.
scanf14.c through scanf17.c are more complicated since they are
actually testing the subtleties of the extension - under what
circumstances is 'a' treated as a modifier letter, etc. I changed all
of them to use %ms instead of %as as well, but duplicated scanf14.c
and scanf16.c as scanf14a.c and scanf16a.c. These still use %as and
are compiled with -std=gnu89 to access the old extension. A bunch of
diagnostic overrides and manual workarounds for the old stdio.h
behavior become unnecessary. Yay!
* include/features.h (__GLIBC_USE_DEPRECATED_SCANF): New __GLIBC_USE
parameter. Only use deprecated scanf when __USE_GNU is defined
and __STDC_VERSION__ is less than 199901L or __cplusplus is less
than 201103L, whichever is relevant for the language being compiled.
* libio/stdio.h, libio/bits/stdio-ldbl.h: Decide whether to redirect
scanf, fscanf, sscanf, vscanf, vfscanf, and vsscanf to their
__isoc99_ variants based only on __GLIBC_USE (DEPRECATED_SCANF).
* wcsmbs/wchar.h: wcsmbs/bits/wchar-ldbl.h: Likewise for
wscanf, fwscanf, swscanf, vwscanf, vfwscanf, and vswscanf.

* sysdeps/ieee754/ldbl-opt/nldbl-vwscanf.c
* sysdeps/ieee754/ldbl-opt/nldbl-wscanf.c:
Override __GLIBC_USE_DEPRECATED_SCANF to 1.
* stdio-common/sscanf.c: Likewise. Remove ldbl_hidden_def for __sscanf.
* stdio-common/isoc99_sscanf.c: Add libc_hidden_def for __isoc99_sscanf.
* include/stdio.h: Provide libc_hidden_proto for __isoc99_sscanf,
not sscanf.
[!__GLIBC_USE (DEPRECATED_SCANF)]: Define sscanf as __isoc99_scanf
with a preprocessor macro.
* stdio-common/bug21.c, stdio-common/scanf14.c:
Use %ms instead of %as, %mS instead of %aS, %m[] instead of %a[];
remove DIAG_IGNORE_NEEDS_COMMENT for -Wformat.
* stdio-common/scanf16.c: Likewise. Add __attribute__ ((format (scanf)))
to xscanf, xfscanf, xsscanf.
* stdio-common/scanf14a.c: New copy of scanf14.c which still uses
%as, %aS, %a[]. Remove DIAG_IGNORE_NEEDS_COMMENT for -Wformat.
* stdio-common/scanf16a.c: New copy of scanf16.c which still uses
%as, %aS, %a[]. Add __attribute__ ((format (scanf))) to xscanf,
xfscanf, xsscanf.
* stdio-common/scanf15.c, stdio-common/scanf17.c: No need to
override feature selection macros or provide definitions of u_char etc.
* stdio-common/Makefile (tests): Add scanf14a and scanf16a.
(CFLAGS-scanf15.c, CFLAGS-scanf17.c): Remove.
(CFLAGS-scanf14a.c, CFLAGS-scanf16a.c): New. Compile these files
with -std=gnu89.

* An archaic GNU extension to scanf, under which '%as', '%aS', and '%a[...]'
|
|
|
|
|
|
meant to scan a string and allocate space for it with malloc, is now
|
|
|
|
|
|
restricted to programs compiled in C89 or C++98 mode with _GNU_SOURCE
|
|
|
|
|
|
defined. This extension conflicts with C99's use of '%a' to scan a
|
|
|
|
|
|
hexadecimal floating-point number, which is now available to programs
|
|
|
|
|
|
compiled as C99 or C++11 or higher, regardless of _GNU_SOURCE.
|
|
|
|
|
|
|
|
|
|
|
|
POSIX.1-2008 includes the feature of allocating a buffer for string input
|
|
|
|
|
|
with malloc, using the modifier letter 'm' instead. Programs using
|
|
|
|
|
|
'%as', '%aS', or '%a[...]' with the old GNU meaning should change to
|
|
|
|
|
|
'%ms', '%mS', or '%m[...]' respectively. Programs that wish to use the
|
|
|
|
|
|
C99 '%a' no longer need to avoid _GNU_SOURCE.
|
|
|
|
|
|
|
|
|
|
|
|
GCC's -Wformat warnings can detect most uses of this extension, as long
|
|
|
|
|
|
as all functions that call vscanf, vfscanf, or vsscanf are annotated with
|
|
|
|
|
|
__attribute__ ((format (scanf, ...))).

|
|
|
2018-07-28 03:56:24 +08:00
|
|
|
|
* The localization data for ISO 14651 is updated to match the 2016
|
|
|
|
|
|
Edition 4 release of the standard, this matches data provided by
|
|
|
|
|
|
Unicode 9.0.0. This update introduces significant improvements to the
|
|
|
|
|
|
collation of Unicode characters. This release deviates slightly from
|
|
|
|
|
|
the standard in that the collation element ordering for lowercase and
|
|
|
|
|
|
uppercase LATIN script characters is adjusted to ensure that regular
|
|
|
|
|
|
expressions with ranges like [a-z] and [A-Z] don't interleave e.g. A
|
|
|
|
|
|
is not matched by [a-z]. With the update many locales have been
|
|
|
|
|
|
updated to take advantage of the new collation information. The new
|
|
|
|
|
|
collation information has increased the size of the compiled locale
|
|
|
|
|
|
archive or binary locales.

|
* The GNU C Library can now be compiled with support for Intel CET, AKA
|
|
|
|
|
|
Intel Control-flow Enforcement Technology. When the library is built
|
|
|
|
|
|
with --enable-cet, the resulting glibc is protected with indirect
|
|
|
|
|
|
branch tracking (IBT) and shadow stack (SHSTK). CET-enabled glibc is
|
|
|
|
|
|
compatible with all existing executables and shared libraries. This
|
|
|
|
|
|
feature is currently supported on i386, x86_64 and x32 with GCC 8 and
|
|
|
|
|
|
binutils 2.29 or later. Note that CET-enabled glibc requires CPUs
|
|
|
|
|
|
capable of multi-byte NOPs, like x86-64 processors as well as Intel
|
2018-07-20 03:04:56 +08:00
|
|
|
|
Pentium Pro or newer. NOTE: --enable-cet has been tested for i686,
|
|
|
|
|
|
x86_64 and x32 on non-CET processors. --enable-cet has been tested
|
|
|
|
|
|
for x86_64 and x32 on CET SDVs, but Intel CET support hasn't been
|
|
|
|
|
|
validated for i686.

|
|
|
|
|
2018-07-06 01:06:43 +08:00
|
|
|
|
* The GNU C Library now has correct support for ABSOLUTE symbols
|
|
|
|
|
|
(SHN_ABS-relative symbols). Previously such ABSOLUTE symbols were
|
|
|
|
|
|
relocated incorrectly or in some cases discarded. The GNU linker can
|
|
|
|
|
|
make use of the newer semantics, but it must communicate it to the
|
|
|
|
|
|
dynamic loader by setting the ELF file's identification (EI_ABIVERSION
|
|
|
|
|
|
field) to indicate such support is required.
|
|
|
|
|
|
|
2018-06-19 00:23:44 +08:00
|
|
|
|
* Unicode 11.0.0 Support: Character encoding, character type info, and
|
|
|
|
|
|
transliteration tables are all updated to Unicode 11.0.0, using
|
|
|
|
|
|
generator scripts contributed by Mike FABIAN (Red Hat).
|
|
|

Add narrowing add functions.
This patch adds the narrowing add functions from TS 18661-1 to glibc's
libm: fadd, faddl, daddl, f32addf64, f32addf32x, f32xaddf64 for all
configurations; f32addf64x, f32addf128, f64addf64x, f64addf128,
f32xaddf64x, f32xaddf128, f64xaddf128 for configurations with
_Float64x and _Float128; __nldbl_daddl for ldbl-opt. As discussed for
the build infrastructure patch, tgmath.h support is deliberately
deferred, and FP_FAST_* macros are not applicable without optimized
function implementations.
Function implementations are added for all relevant pairs of formats
(including certain cases of a format and itself where more than one
type has that format). The main implementations use round-to-odd, or
a trivial computation in the case where both formats are the same or
where the wider format is IBM long double (in which case we don't
attempt to be correctly rounding). The sysdeps/ieee754/soft-fp
implementations use soft-fp, and are used automatically for
configurations without exceptions and rounding modes by virtue of
existing Implies files. As previously discussed, optimized versions
for particular architectures are possible, but not included.
i386 gets a special version of f32xaddf64 to avoid problems with
double rounding (similar to the existing fdim version), since this
function must round just once without an intermediate rounding to long
double. (No such special version is needed for any other function,
because the nontrivial functions use round-to-odd, which does the
intermediate computation with the rounding mode set to round-to-zero,
and double rounding is OK except in round-to-nearest mode, so is OK
for that intermediate round-to-zero computation.) mul and div will
need slightly different special versions for i386 (using round-to-odd
on long double instead of precision control) because of the
possibility of inexact intermediate results in the subnormal range for
double.
To reduce duplication among the different function implementations,
math-narrow.h gets macros CHECK_NARROW_ADD, NARROW_ADD_ROUND_TO_ODD
and NARROW_ADD_TRIVIAL.
In the trivial cases and for any architecture-specific optimized
implementations, the overhead of the errno setting might be
significant, but I think that's best handled through compiler built-in
functions rather than providing separate no-errno versions in glibc
(and likewise there are no __*_finite entry points for these function
provided, __*_finite effectively being no-errno versions at present in
most cases).
Tested for x86_64 and x86, with both GCC 6 and GCC 7. Tested for
mips64 (all three ABIs, both hard and soft float) and powerpc with GCC
7. Tested with build-many-glibcs.py with both GCC 6 and GCC 7.

Add narrowing subtract functions.
This patch adds the narrowing subtract functions from TS 18661-1 to
glibc's libm: fsub, fsubl, dsubl, f32subf64, f32subf32x, f32xsubf64
for all configurations; f32subf64x, f32subf128, f64subf64x,
f64subf128, f32xsubf64x, f32xsubf128, f64xsubf128 for configurations
with _Float64x and _Float128; __nldbl_dsubl for ldbl-opt.
The changes are essentially the same as for the narrowing add
functions, so the description of those generally applies to this patch
as well.
Tested for x86_64, x86, mips64 (all three ABIs, both hard and soft
float) and powerpc, and with build-many-glibcs.py.

Add narrowing multiply functions.
This patch adds the narrowing multiply functions from TS 18661-1 to
glibc's libm: fmul, fmull, dmull, f32mulf64, f32mulf32x, f32xmulf64
for all configurations; f32mulf64x, f32mulf128, f64mulf64x,
f64mulf128, f32xmulf64x, f32xmulf128, f64xmulf128 for configurations
with _Float64x and _Float128; __nldbl_dmull for ldbl-opt.
The changes are mostly essentially the same as for the narrowing add
functions, so the description of those generally applies to this patch
as well. f32xmulf64 for i386 cannot use precision control as used for
add and subtract, because that would result in double rounding for
subnormal results, so that uses round-to-odd with long double
intermediate result instead. The soft-fp support involves adding a
new FP_TRUNC_COOKED since soft-fp multiplication uses cooked inputs
and outputs.
Tested for x86_64, x86, mips64 (all three ABIs, both hard and soft
float) and powerpc, and with build-many-glibcs.py.

Improve DST handling (Bug 23102, Bug 21942, Bug 18018, Bug 23259).
This commit improves DST handling significantly in the following
ways: firstly is_dst () is overhauled to correctly process DST
sequences that would be accepted given the ELF gABI. This means that
we actually now accept slightly more sequences than before. Now we
accept $ORIGIN$ORIGIN, but in the past we accepted only $ORIGIN\0 or
$ORIGIN/..., but this kind of behaviour results in unexpected
and uninterpreted DST sequences being used as literal search paths
leading to security defects. Therefore the first step in correcting
this defect is making is_dst () properly account for all DSTs
and making the function context free in the sense that it counts
DSTs without knowledge of path, or AT_SECURE. Next, _dl_dst_count ()
is also simplified to count all DSTs regardless of context.
Then in _dl_dst_substitute () we reintroduce context-dependent
processing for such things as AT_SECURE handling. At the level of
_dl_dst_substitute we can have access to things like the true start
of the string sequence to validate $ORIGIN-based paths rooted in
trusted directories. Lastly, we tighten up the accepted sequences
in AT_SECURE, and avoid leaving known unexpanded DSTs, this is
noted in the NEWS entry.
Verified with a sequence of 68 tests on x86_64 that cover
non-AT_SECURE and AT_SECURE testing using a sysroot (requires root
to run). The tests cover cases for bug 23102, bug 21942, bug 18018,
and bug 23259. These tests are not yet appropriate for the glibc
regression testsuite, but with the upcoming test-in-container testing
framework it should be possible to include these tests upstream soon.

* Parsing of dynamic string tokens in DT_RPATH, DT_RUNPATH, DT_NEEDED,
|
|
|
|
|
|
DT_AUXILIARY, and DT_FILTER has been expanded to support the full
|
|
|
|
|
|
range of ELF gABI expressions including such constructs as
|
|
|
|
|
|
'$ORIGIN$ORIGIN' (if valid). For SUID/GUID applications the rules
|
|
|
|
|
|
have been further restricted, and where in the past a dynamic string
|
|
|
|
|
|
token sequence may have been interpreted as a literal string it will
|
|
|
|
|
|
now cause a load failure. These load failures were always considered
|
|
|
|
|
|
unspecified behaviour from the perspective of the dynamic loader, and
|
|
|
|
|
|
for safety are now load errors e.g. /foo/${ORIGIN}.so in DT_NEEDED
|
|
|
|
|
|
results in a load failure now.

|
|
|
|
* The nonstandard header files <libio.h> and <_G_config.h> are no longer
|
|
|
|
|
|
installed. Software that was using either header should be updated to
|
|
|
|
|
|
use standard <stdio.h> interfaces instead.
|
|
|
|
|
|
|
|
|
|
|
|
* The stdio functions 'getc' and 'putc' are no longer defined as macros.
|
|
|
|
|
|
This was never required by the C standard, and the macros just expanded
|
|
|
|
|
|
to call alternative names for the same functions. If you hoped getc and
|
|
|
|
|
|
putc would provide performance improvements over fgetc and fputc, instead
|
|
|
|
|
|
investigate using (f)getc_unlocked and (f)putc_unlocked, and, if
|
|
|
|
|
|
necessary, flockfile and funlockfile.
|
|
|
|
|
|
|
|
|
|
|
|
* All stdio functions now treat end-of-file as a sticky condition. If you
|
|
|
|
|
|
read from a file until EOF, and then the file is enlarged by another
|
|
|
|
|
|
process, you must call clearerr or another function with the same effect
|
|
|
|
|
|
(e.g. fseek, rewind) before you can read the additional data. This
|
|
|
|
|
|
corrects a longstanding C99 conformance bug. It is most likely to affect
|
|
|
|
|
|
programs that use stdio to read interactive input from a terminal.

(Bug #1190.)
|
|
|
|
|
|
|
|
|
|
|
|
* The macros 'major', 'minor', and 'makedev' are now only available from
|
|
|
|
|
|
the header <sys/sysmacros.h>; not from <sys/types.h> or various other
|
|
|
|
|
|
headers that happen to include <sys/types.h>. These macros are rarely
|
|
|
|
|
|
used, not part of POSIX nor XSI, and their names frequently collide with
|
|
|
|
|
|
user code; see https://sourceware.org/bugzilla/show_bug.cgi?id=19239 for
|
|
|
|
|
|
further explanation.
|
|
|
|
|
|
|
|
|
|
|
|
<sys/sysmacros.h> is a GNU extension. Portable programs that require
|
|
|
|
|
|
these macros should first include <sys/types.h>, and then include
|
|
|
|
|
|
<sys/sysmacros.h> if __GNU_LIBRARY__ is defined.

Make llseek a compat symbol (bug 18471).
The llseek function name is an obsolete, Linux-specific, unprototyped
name for lseek64 with a link-time warning. This patch completes the
obsoletion of this function name by making it into a compat symbol,
not available for newly linked programs and not included in the ABI
for new ports.
When a compat symbol is defined in syscalls.list, the code for that
function is not built at all for static linking unless some non-compat
symbol for that function is also defined with an explicit symbol
version, so an explicit symbol version for lseek64 is added to the
MIPS n32 syscalls.list. The case in make-syscalls.sh that handles
such explicit non-compat symbol versions then needs to be changed to
use weak_alias instead of strong_alias when the syscall is built
outside of libc, to avoid linknamespace failures from a strong lseek64
symbol in static libpthread.
The x32 llseek.S was as far as I could tell already unused (nothing
builds an llseek.* source file, at least since the lseek / lseek64 /
llseek consolidation), so is removed in this patch as well.
Tested for x86_64 and x86, and with build-many-glibcs.py.
[BZ #18471]
* sysdeps/unix/make-syscalls.sh (emit_weak_aliases): Use weak
aliases for non-libc case of versioned symbols.
* sysdeps/unix/sysv/linux/lseek64.c: Include <shlib-compat.h>.
(llseek): Define as compat symbol if
[SHLIB_COMPAT (libc, GLIBC_2_0, GLIBC_2_28)], not as weak alias
with link warning.
* sysdeps/unix/sysv/linux/mips/mips64/n32/syscalls.list (llseek):
Make into a compat symbol, disabled for minimum symbol version
GLIBC_2.28 and later.

Fix Linux fcntl OFD locks for non-LFS architectures (BZ#20251)
This patch fixes the OFD ("file private") locks for architectures that
support non-LFS flock definition (__USE_FILE_OFFSET64 not defined). The
issue in this case is both F_OFD_{GETLK,SETLK,SETLKW} and
F_{SET,GET}L{W}K64 expects a flock64 argument and when using old
F_OFD_* flags with a non LFS flock argument the kernel might interpret
the underlying data wrongly. Kernel idea originally was to avoid using
such flags in non-LFS syscall, but since GLIBC uses fcntl with LFS
semantic as default it is possible to provide the functionality and
avoid the bogus struct kernel passing by adjusting the struct manually
for the required flags.
The idea follows other LFS interfaces that provide two symbols:
1. A new LFS fcntl64 is added on default ABI with the usual macros to
select it for FILE_OFFSET_BITS=64.
2. The Linux non-LFS fcntl use a stack allocated struct flock64 for
F_OFD_{GETLK,SETLK,SETLKW} copy the results on the user provided
struct.
3. Keep a compat symbol with old broken semantic for architectures
that do not define __OFF_T_MATCHES_OFF64_T.
So for architectures which defines __USE_FILE_OFFSET64, fcntl64 will
aliased to fcntl and no adjustment would be required. So to actually
use F_OFD_* with LFS support the source must be built with LFS support
(_FILE_OFFSET_BITS=64).
Also F_OFD_SETLKW command is handled a cancellation point, as for
F_SETLKW{64}.
Checked on x86_64-linux-gnu and i686-linux-gnu.

Disallow use of DES encryption functions in new programs.
The functions encrypt, setkey, encrypt_r, setkey_r, cbc_crypt,
ecb_crypt, and des_setparity should not be used in new programs,
because they use the DES block cipher, which is unacceptably weak by
modern standards. Demote all of them to compatibility symbols, and
remove their prototypes from installed headers. cbc_crypt, ecb_crypt,
and des_setparity were already compat symbols when glibc was
configured with --disable-obsolete-rpc.
POSIX requires encrypt and setkey to be available when _XOPEN_CRYPT
is defined, so this change also removes the definition of X_OPEN_CRYPT
from <unistd.h>.
The entire "DES Encryption" section is dropped from the manual, as is
the mention of AUTH_DES and FIPS 140-2 in the introduction to
crypt.texi. The documentation of 'memfrob' cross-referenced the DES
Encryption section, which is replaced by a hyperlink to libgcrypt, and
while I was in there I spruced up the actual documentation of
'memfrob' and 'strfry' a little. It's still fairly jokey, because
those functions _are_ jokes, but they do also have real use cases, so
people trying to use them for real should have all the information
they need.
DES-based authentication for Sun RPC is also insecure and should be
deprecated or even removed, but maybe that can be left as TI-RPC's
problem.
2018-06-29 22:53:18 +08:00
|
|
|
|
* The obsolete functions encrypt, encrypt_r, setkey, setkey_r, cbc_crypt,
|
|
|
|
|
|
ecb_crypt, and des_setparity are no longer available to newly linked
|
|
|
|
|
|
binaries, and the headers <rpc/des_crypt.h> and <rpc/rpc_des.h> are no
|
|
|
|
|
|
longer installed. These functions encrypted and decrypted data with the
|
|
|
|
|
|
DES block cipher, which is no longer considered secure. Software that
|
|
|
|
|
|
still uses these functions should switch to a modern cryptography library,
|
|
|
|
|
|
such as libgcrypt.
|
|
|
|
|
|
|
|
|
|
|
|
* Reflecting the removal of the encrypt and setkey functions above, the
|
|
|
|
|
|
macro _XOPEN_CRYPT is no longer defined. As a consequence, the crypt
|
|
|
|
|
|
function is no longer declared unless _DEFAULT_SOURCE or _GNU_SOURCE is
|
|
|
|
|
|
enabled.
|

|
|
|
|
|
|
|
|
|
* The obsolete function fcrypt is no longer available to newly linked
|
|
|

|
binaries. It was just another name for the standard function crypt,
|
|
|
|
|
|
and it has not appeared in any header file in many years.

2018-06-29 22:53:47 +08:00
|

* We have tentative plans to hand off maintenance of the passphrase-hashing
|
|
|
|
|
|
library, libcrypt, to a separate development project that will, we hope,
|
|
|
|
|
|
keep up better with new passphrase-hashing algorithms. We will continue
|
|
|
|
|
|
to declare 'crypt' in <unistd.h>, and programs that use 'crypt' or
|
|
|
|
|
|
'crypt_r' should not need to change at all; however, distributions will
|
|
|
|
|
|
need to install <crypt.h> and libcrypt from a separate project.
|
|
|
|
|
|
|
|
|
|
|
|
In this release, if the configure option --disable-crypt is used, glibc
|
|
|
|
|
|
will not install <crypt.h> or libcrypt, making room for the separate
|
|
|
|
|
|
project's versions of these files. The plan is to make this the default
|
|
|
|
|
|
behavior in a future release.

Add --enable-static-pie configure option to build static PIE [BZ #19574]
Static PIE extends address space layout randomization to static
executables. It provides additional security hardening benefits at
the cost of some memory and performance.
Dynamic linker, ld.so, is a standalone program which can be loaded at
any address. This patch adds a configure option, --enable-static-pie,
to embed the part of ld.so in static executable to create static position
independent executable (static PIE). A static PIE is similar to static
executable, but can be loaded at any address without help from a dynamic
linker. When --enable-static-pie is used to configure glibc, libc.a is
built as PIE and all static executables, including tests, are built as
static PIE. The resulting libc.a can be used together with GCC 8 or
above to build static PIE with the compiler option, -static-pie. But
GCC 8 isn't required to build glibc with --enable-static-pie. Only GCC
with PIE support is needed. When an older GCC is used to build glibc
with --enable-static-pie, proper input files are passed to linker to
create static executables as static PIE, together with "-z text" to
prevent dynamic relocations in read-only segments, which are not allowed
in static PIE.
The following changes are made for static PIE:
1. Add a new function, _dl_relocate_static_pie, to:
a. Get the run-time load address.
b. Read the dynamic section.
c. Perform dynamic relocations.
Dynamic linker also performs these steps. But static PIE doesn't load
any shared objects.
2. Call _dl_relocate_static_pie at entrance of LIBC_START_MAIN in
libc.a. crt1.o, which is used to create dynamic and non-PIE static
executables, is updated to include a dummy _dl_relocate_static_pie.
rcrt1.o is added to create static PIE, which will link in the real
_dl_relocate_static_pie. grcrt1.o is also added to create static PIE
with -pg. GCC 8 has been updated to support rcrt1.o and grcrt1.o for
static PIE.
Static PIE can work on all architectures which support PIE, provided:
1. Target must support accessing of local functions without dynamic
relocations, which is needed in start.S to call __libc_start_main with
function addresses of __libc_csu_init, __libc_csu_fini and main. All
functions in static PIE are local functions. If PIE start.S can't reach
main () defined in a shared object, the code sequence:
pass address of local_main to __libc_start_main
...
local_main:
tail call to main via PLT
can be used.
2. start.S is updated to check PIC instead SHARED for PIC code path and
avoid dynamic relocation, when PIC is defined and SHARED isn't defined,
to support static PIE.
3. All assembly codes are updated check PIC instead SHARED for PIC code
path to avoid dynamic relocations in read-only sections.
4. All assembly codes are updated check SHARED instead PIC for static
symbol name.
5. elf_machine_load_address in dl-machine.h are updated to support static
PIE.
6. __brk works without TLS nor dynamic relocations in read-only section
so that it can be used by __libc_setup_tls to initializes TLS in static
PIE.
NB: When glibc is built with GCC defaulted to PIE, libc.a is compiled
with -fPIE, regardless if --enable-static-pie is used to configure glibc.
When glibc is configured with --enable-static-pie, libc.a is compiled
with -fPIE, regardless whether GCC defaults to PIE or not. The same
libc.a can be used to build both static executable and static PIE.
There is no need for separate PIE copy of libc.a.
On x86-64, the normal static sln:
text data bss dec hex filename
625425 8284 5456 639165 9c0bd elf/sln
the static PIE sln:
text data bss dec hex filename
657626 20636 5392 683654 a6e86 elf/sln
The code size is increased by 5% and the binary size is increased by 7%.
Linker requirements to build glibc with --enable-static-pie:
1. Linker supports --no-dynamic-linker to remove PT_INTERP segment from
static PIE.
2. Linker can create working static PIE. The x86-64 linker needs the
fix for
https://sourceware.org/bugzilla/show_bug.cgi?id=21782
The i386 linker needs to be able to convert "movl main@GOT(%ebx), %eax"
to "leal main@GOTOFF(%ebx), %eax" if main is defined locally.
Binutils 2.29 or above are OK for i686 and x86-64. But linker status for
other targets need to be verified.
3. Linker should resolve undefined weak symbols to 0 in static PIE:
https://sourceware.org/bugzilla/show_bug.cgi?id=22269
4. Many ELF backend linkers incorrectly check bfd_link_pic for TLS
relocations, which should check bfd_link_executable instead:
https://sourceware.org/bugzilla/show_bug.cgi?id=22263
Tested on aarch64, i686 and x86-64.

--enable-static-pie with all patches for static PIE applied have the

Add --enable-static-pie configure option to build static PIE [BZ #19574]
Static PIE extends address space layout randomization to static
executables. It provides additional security hardening benefits at
the cost of some memory and performance.
Dynamic linker, ld.so, is a standalone program which can be loaded at
any address. This patch adds a configure option, --enable-static-pie,
to embed the part of ld.so in static executable to create static position
independent executable (static PIE). A static PIE is similar to static
executable, but can be loaded at any address without help from a dynamic
linker. When --enable-static-pie is used to configure glibc, libc.a is
built as PIE and all static executables, including tests, are built as
static PIE. The resulting libc.a can be used together with GCC 8 or
above to build static PIE with the compiler option, -static-pie. But
GCC 8 isn't required to build glibc with --enable-static-pie. Only GCC
with PIE support is needed. When an older GCC is used to build glibc
with --enable-static-pie, proper input files are passed to linker to
create static executables as static PIE, together with "-z text" to
prevent dynamic relocations in read-only segments, which are not allowed
in static PIE.
The following changes are made for static PIE:
1. Add a new function, _dl_relocate_static_pie, to:
a. Get the run-time load address.
b. Read the dynamic section.
c. Perform dynamic relocations.
Dynamic linker also performs these steps. But static PIE doesn't load
any shared objects.
2. Call _dl_relocate_static_pie at entrance of LIBC_START_MAIN in
libc.a. crt1.o, which is used to create dynamic and non-PIE static
executables, is updated to include a dummy _dl_relocate_static_pie.
rcrt1.o is added to create static PIE, which will link in the real
_dl_relocate_static_pie. grcrt1.o is also added to create static PIE
with -pg. GCC 8 has been updated to support rcrt1.o and grcrt1.o for
static PIE.
Static PIE can work on all architectures which support PIE, provided:
1. Target must support accessing of local functions without dynamic
relocations, which is needed in start.S to call __libc_start_main with
function addresses of __libc_csu_init, __libc_csu_fini and main. All
functions in static PIE are local functions. If PIE start.S can't reach
main () defined in a shared object, the code sequence:
pass address of local_main to __libc_start_main
...
local_main:
tail call to main via PLT
can be used.
2. start.S is updated to check PIC instead SHARED for PIC code path and
avoid dynamic relocation, when PIC is defined and SHARED isn't defined,
to support static PIE.
3. All assembly codes are updated check PIC instead SHARED for PIC code
path to avoid dynamic relocations in read-only sections.
4. All assembly codes are updated check SHARED instead PIC for static
symbol name.
5. elf_machine_load_address in dl-machine.h are updated to support static
PIE.
6. __brk works without TLS nor dynamic relocations in read-only section
so that it can be used by __libc_setup_tls to initializes TLS in static
PIE.
NB: When glibc is built with GCC defaulted to PIE, libc.a is compiled
with -fPIE, regardless if --enable-static-pie is used to configure glibc.
When glibc is configured with --enable-static-pie, libc.a is compiled
with -fPIE, regardless whether GCC defaults to PIE or not. The same
libc.a can be used to build both static executable and static PIE.
There is no need for separate PIE copy of libc.a.
On x86-64, the normal static sln:
text data bss dec hex filename
625425 8284 5456 639165 9c0bd elf/sln
the static PIE sln:
text data bss dec hex filename
657626 20636 5392 683654 a6e86 elf/sln
The code size is increased by 5% and the binary size is increased by 7%.
Linker requirements to build glibc with --enable-static-pie:
1. Linker supports --no-dynamic-linker to remove PT_INTERP segment from
static PIE.
2. Linker can create working static PIE. The x86-64 linker needs the
fix for

The i386 linker needs to be able to convert "movl main@GOT(%ebx), %eax"
to "leal main@GOTOFF(%ebx), %eax" if main is defined locally.
Binutils 2.29 or above are OK for i686 and x86-64. But linker status for
other targets need to be verified.
3. Linker should resolve undefined weak symbols to 0 in static PIE:
https://sourceware.org/bugzilla/show_bug.cgi?id=22269
4. Many ELF backend linkers incorrectly check bfd_link_pic for TLS
relocations, which should check bfd_link_executable instead:
https://sourceware.org/bugzilla/show_bug.cgi?id=22263
Tested on aarch64, i686 and x86-64.

Add --enable-static-pie configure option to build static PIE [BZ #19574]
Static PIE extends address space layout randomization to static
executables. It provides additional security hardening benefits at
the cost of some memory and performance.
Dynamic linker, ld.so, is a standalone program which can be loaded at
any address. This patch adds a configure option, --enable-static-pie,
to embed the part of ld.so in static executable to create static position
independent executable (static PIE). A static PIE is similar to static
executable, but can be loaded at any address without help from a dynamic
linker. When --enable-static-pie is used to configure glibc, libc.a is
built as PIE and all static executables, including tests, are built as
static PIE. The resulting libc.a can be used together with GCC 8 or
above to build static PIE with the compiler option, -static-pie. But
GCC 8 isn't required to build glibc with --enable-static-pie. Only GCC
with PIE support is needed. When an older GCC is used to build glibc
with --enable-static-pie, proper input files are passed to linker to
create static executables as static PIE, together with "-z text" to
prevent dynamic relocations in read-only segments, which are not allowed
in static PIE.
The following changes are made for static PIE:
1. Add a new function, _dl_relocate_static_pie, to:
a. Get the run-time load address.
b. Read the dynamic section.
c. Perform dynamic relocations.
Dynamic linker also performs these steps. But static PIE doesn't load
any shared objects.
2. Call _dl_relocate_static_pie at entrance of LIBC_START_MAIN in
libc.a. crt1.o, which is used to create dynamic and non-PIE static
executables, is updated to include a dummy _dl_relocate_static_pie.
rcrt1.o is added to create static PIE, which will link in the real
_dl_relocate_static_pie. grcrt1.o is also added to create static PIE
with -pg. GCC 8 has been updated to support rcrt1.o and grcrt1.o for
static PIE.
Static PIE can work on all architectures which support PIE, provided:
1. Target must support accessing of local functions without dynamic
relocations, which is needed in start.S to call __libc_start_main with
function addresses of __libc_csu_init, __libc_csu_fini and main. All
functions in static PIE are local functions. If PIE start.S can't reach
main () defined in a shared object, the code sequence:
pass address of local_main to __libc_start_main
...
local_main:
tail call to main via PLT
can be used.
2. start.S is updated to check PIC instead SHARED for PIC code path and
avoid dynamic relocation, when PIC is defined and SHARED isn't defined,
to support static PIE.
3. All assembly codes are updated check PIC instead SHARED for PIC code
path to avoid dynamic relocations in read-only sections.
4. All assembly codes are updated check SHARED instead PIC for static
symbol name.
5. elf_machine_load_address in dl-machine.h are updated to support static
PIE.
6. __brk works without TLS nor dynamic relocations in read-only section
so that it can be used by __libc_setup_tls to initializes TLS in static
PIE.
NB: When glibc is built with GCC defaulted to PIE, libc.a is compiled
with -fPIE, regardless if --enable-static-pie is used to configure glibc.
When glibc is configured with --enable-static-pie, libc.a is compiled
with -fPIE, regardless whether GCC defaults to PIE or not. The same
libc.a can be used to build both static executable and static PIE.
There is no need for separate PIE copy of libc.a.
On x86-64, the normal static sln:
text data bss dec hex filename
625425 8284 5456 639165 9c0bd elf/sln
the static PIE sln:
text data bss dec hex filename
657626 20636 5392 683654 a6e86 elf/sln
The code size is increased by 5% and the binary size is increased by 7%.
Linker requirements to build glibc with --enable-static-pie:
1. Linker supports --no-dynamic-linker to remove PT_INTERP segment from
static PIE.
2. Linker can create working static PIE. The x86-64 linker needs the
fix for
https://sourceware.org/bugzilla/show_bug.cgi?id=21782
The i386 linker needs to be able to convert "movl main@GOT(%ebx), %eax"
to "leal main@GOTOFF(%ebx), %eax" if main is defined locally.
Binutils 2.29 or above are OK for i686 and x86-64. But linker status for
other targets need to be verified.
3. Linker should resolve undefined weak symbols to 0 in static PIE:
https://sourceware.org/bugzilla/show_bug.cgi?id=22269
4. Many ELF backend linkers incorrectly check bfd_link_pic for TLS
relocations, which should check bfd_link_executable instead:
https://sourceware.org/bugzilla/show_bug.cgi?id=22263
Tested on aarch64, i686 and x86-64.

Add _Float128 function aliases.
This patch adds support for *f128 function aliases on platforms where
long double has the binary128 format (and thus GCC 7 provides the
_Float128 type with the same ABI as long double but as a distinct type
in terms of C type compatibility). This is the same API as provided
in glibc 2.26 for powerpc64le / x86_64 / x86 / ia64 where _Float128
has a different format from long double, with the bulk of the API
coming from TS 18661-3. All the functions alias the corresponding
long double functions, and __* function names are not provided since
those are only needed once for each floating-point format, not more
than once for different types with the same format (so for example,
-ffinite-math-only maps foof128 to __fool_finite, while type-generic
macros end up calling e.g. __issignalingl for _Float128 arguments on
such platforms).
The preparation for this feature was done in previous patches, so this
one just needs to add the relevant makefile and header definitions,
and update macro definitions of libm_alias_ldouble_other_r, to turn on
the feature, and update documentation and ABI baselines.

Add _Float64x function aliases.
This patch continues filling out TS 18661-3 support by adding *f64x
function aliases on platforms with _Float64x support. (It so happens
the set of such platforms is exactly the same as the set of platforms
with _Float128 support, although on x86_64, x86 and ia32 the _Float64x
format is Intel extended rather than binary128.) The API provided
corresponds exactly to that provided for _Float128, mostly coming from
TS 18661-3. As these functions always alias those for another type
(long double, _Float128 or both), __* function names are not provided,
as in other cases of alias types.
Given the preparation done in previous patches, this one just enables
the feature via Makeconfig and bits/floatn.h, adds symbol versions,
and updates documentation and ABI baselines. The symbol versions are
present unconditionally as GLIBC_2.27 in the relevant Versions files,
as it's OK for those to specify versions for functions that may not be
present in some configurations; no additional complexity is needed
unless in future some configuration gains support for this type that
didn't have such support in 2.27. The Makeconfig additions for ia64
and x86 aren't strictly needed, as those configurations also get
float64x-alias-fcts definitions from
sysdeps/ieee754/float128/Makeconfig, but still seem appropriate given
that _Float64x is not _Float128 for those configurations.
A libm-test-ulps update for x86 is included. This is because
bits/mathinline.h does not have _Float64x support added and for two
functions the use of out-of-line functions results in increased ulps
(ifloat64x shares ulps with ildouble / ifloat128 as appropriate).
Given that we'd like generally to eliminate bits/mathinline.h
optimizations, preferring to have such optimizations in GCC instead,
it seems reasonable not to add such support there for new types. GCC
support for _FloatN / _FloatNx built-in functions is limited, but has
been improved in GCC 8, and at some point I hope the full set of libm
built-in functions in GCC, and other optimizations with
per-floating-type aspects, will be enabled for all _FloatN / _FloatNx
types.
Tested for x86_64 and x86, and with build-many-glibcs.py, with both
GCC 6 and GCC 7.

Add _Float64x function aliases.
This patch continues filling out TS 18661-3 support by adding *f64x
function aliases on platforms with _Float64x support. (It so happens
the set of such platforms is exactly the same as the set of platforms
with _Float128 support, although on x86_64, x86 and ia32 the _Float64x
format is Intel extended rather than binary128.) The API provided
corresponds exactly to that provided for _Float128, mostly coming from
TS 18661-3. As these functions always alias those for another type
(long double, _Float128 or both), __* function names are not provided,
as in other cases of alias types.
Given the preparation done in previous patches, this one just enables
the feature via Makeconfig and bits/floatn.h, adds symbol versions,
and updates documentation and ABI baselines. The symbol versions are
present unconditionally as GLIBC_2.27 in the relevant Versions files,
as it's OK for those to specify versions for functions that may not be
present in some configurations; no additional complexity is needed
unless in future some configuration gains support for this type that
didn't have such support in 2.27. The Makeconfig additions for ia64
and x86 aren't strictly needed, as those configurations also get
float64x-alias-fcts definitions from
sysdeps/ieee754/float128/Makeconfig, but still seem appropriate given
that _Float64x is not _Float128 for those configurations.
A libm-test-ulps update for x86 is included. This is because

2017-09-19 06:00:22 +08:00
|
|
|
|
* Support for two grammatical forms of month names has been added.
|
|
|
|
|
|
In a call to strftime, the "%B" and "%b" format specifiers will now
|
|
|
|
|
|
produce the grammatical form required when the month is used as part
|
|
|
|
|
|
of a complete date. New "%OB" and "%Ob" specifiers produce the form
|
|
|
|
|
|
required when the month is named by itself. For instance, in Greek
|
|
|
|
|
|
and in many Slavic and Baltic languages, "%B" will produce the month
|
|
|
|
|
|
in genitive case, and "%OB" will produce the month in nominative case.
|
|
|
|
|
|
|
|
|
|
|
|
In a call to strptime, "%B", "%b", "%h", "%OB", "%Ob", and "%Oh"
|
|
|
|
|
|
are all valid and will all accept any known form of month
|
|
|
|
|
|
name---standalone or complete, abbreviated or full. In a call to
|
|
|
|
|
|
nl_langinfo, the query constants MON_1..12 and ABMON_1..12 return
|
|
|
|
|
|
the strings used by "%B" and "%b", respectively. New query
|
|
|
|
|
|
constants ALTMON_1..12 and _NL_ABALTMON_1..12 return the strings
|
|
|
|
|
|
used by "%OB" and "%Ob", respectively.
|
|
|
|
|
|
|
|
|
|
|
|
In a locale definition file, use "alt_mon" and "ab_alt_mon" to
|
|
|
|
|
|
define the strings for %OB and %Ob, respectively; these have the
|
2018-02-01 08:45:43 +08:00
|
|
|
|
same syntax as "mon" and "abmon". These arrays are optional; if they
|
|
|
|
|
|
are not provided then they have the same content as "mon" and "abmon",
|
|
|
|
|
|
respectively.
|
|
|
|
|
|
|
|
|
|
|
|
These features are provided for locales which define "alt_mon" and/or
|
|
|
|
|
|
"ab_alt_mon" in their locale source data. This release includes such
|
|
|
|
|
|
alternative month name data for the following languages: Belarusian,
|
|
|
|
|
|
Croatian, Greek, Lithuanian, Polish, Russian, and Ukrainian.
|
2017-09-19 06:00:22 +08:00
|
|
|
|
|
|
|
|
|
|
This feature is currently a GNU extension, but it is expected to
|
|
|
|
|
|
be added to the next revision of POSIX, and it is also already
|
|
|
|
|
|
available on some BSD-derived operating systems.

2018-01-24 05:52:39 +08:00
|
|
|
|
locale. The reason for this is that the addition of the new "%OB" and "%Ob",
|
2018-01-24 04:20:01 +08:00
|
|
|
|
support for two grammatical forms of the month names, also extends the locale
|
|
|
|

data binary format. Static applications needing locale support must be
|
|

recompiled to match the runtime and data they are deployed with. In some

distributions there is an upgrade window where dynamically linked applications

may use a new library but the old locale data and also fall back to the

Obsolete matherr, _LIB_VERSION, libieee.a.
This patch obsoletes support for SVID libm error handling (the system
where a user-defined function matherr is called on a libm function
error; only enabled if you also set _LIB_VERSION = _SVID_ or
_LIB_VERSION = _XOPEN_) and the use of the _LIB_VERSION global
variable to control libm error handling. matherr and _LIB_VERSION are
made into compat symbols, not supported for new ports or for static
linking. The libieee.a object file (which sets _LIB_VERSION = _IEEE_,
so disabling errno setting for some functions) is also removed, and
all the related definitions are removed from math.h.
The manual already recommends against using matherr, and it's already
not supported for _Float128 functions (those use new wrappers that
don't support matherr, only errno) - this patch means that it becomes
possible to e.g. add sinf32 as an alias to sinf without that resulting
in undesired matherr support in sinf32 for existing glibc ports.
matherr support is not part of any standard supported by glibc (it was
removed in XPG4).
Because matherr is a function to be defined by the user, of course
user programs defining such a function will still continue to link; it
just quietly won't be used. If they try to write to the library's
copy of _LIB_VERSION to enable SVID error handling, however, they will
get a link error (but if they define their own _LIB_VERSION variable,
they won't).
I expect the most likely case of build failures from this patch to be
programs with unconditional cargo-culted uses of -lieee (based on a
notion of "I want IEEE floating point", not any actual requirement for
that library).
Ideally, the new-port-or-static-linking case would use the new
wrappers used for _Float128. This is not implemented in this patch,
because of the complication of architecture-specific (powerpc32 and
sparc) sqrt wrappers that use _LIB_VERSION and __kernel_standard
directly. Thus, the old wrappers and __kernel_standard are still
built unconditionally, and _LIB_VERSION still exists in static libm.
But when the old wrappers and __kernel_standard are built in the
non-compat case, _LIB_VERSION and matherr are defined as macros so
code to support those features isn't actually built into static libm
or new ports' shared libm after this patch.
I intend to move to the new wrappers for static libm and new ports in
followup patches. I believe the sqrt wrappers for powerpc32 and sparc
can reasonably be removed. GCC already optimizes the normal case of
sqrt by generating code that uses a hardware instruction and only
calls the sqrt function if the argument was negative (if
-fno-math-errno, of course, it just uses the hardware instruction
without any check for negative argument being needed). Thus those
wrappers will only actually get called in the case of negative
arguments, which is not a case it makes sense to optimize for. But
even without removing the powerpc32 and sparc wrappers it should still
be possible to move to the new wrappers for static libm and new ports,
just without having those dubious architecture-specific optimizations
in static libm.
Everything said about matherr equally applies to matherrf and matherrl
(IA64-specific, undocumented), except that the structure of IA64 libm
means it won't be converted to using the new wrappers (it doesn't use
the old ones either, but its own error-handling code instead).
As with other tests of compat symbols, I expect test-matherr and
test-matherr-2 to need to become appropriately conditional once we
have a system for disabling such tests for ports too new to have the
relevant symbols.

Remove add-ons mechanism.
glibc has an add-ons mechanism to allow additional software to be
integrated into the glibc build. Such add-ons may be within the glibc
source tree, or outside it at a path passed to the --enable-add-ons
configure option.
localedata and crypt were once add-ons, distributed in separate
release tarballs, but long since stopped using that mechanism.
Linuxthreads was always an add-on. Ports spent some time as an add-on
with separate release tarballs, then was first moved into the glibc
source tree, then had its sysdeps files moved into the main sysdeps
hierarchy so the add-ons mechanism was no longer used. NPTL spent
some time as an add-on in the main glibc tree before stopping using
the add-on mechanism. libidn used to have separate release tarballs
but no longer does so, but still uses the add-ons mechanism within the
glibc source tree. Various other software has supported building with
the add-ons mechanism at times in the past, but I don't think any is
still widely used.
Add-ons involve significant, little-used complexity in the glibc build
system, and make it hard to understand what the space of possible
glibc configurations is. This patch removes the add-ons mechanism.
libidn is now built via the Subdirs mechanism to cause any
configuration using sysdeps/unix/inet to build libidn; HAVE_LIBIDN
(which effectively means shared libraries are available) is now
defined via sysdeps/unix/inet/configure. Various references to
add-ons around the source tree are removed (in the case of maint.texi,
the example list of sysdeps directories is still very out of date).
Externally maintained ports should now put their files in the normal
sysdeps directory structure rather than being arranged as add-ons;
they probably need to change e.g. elf.h anyway, rather than actually
being able to work just as a drop-in subtree. Hurd libpthread should
be arranged similarly to NPTL, so some files might go in a
hurd-pthreads (or similar) top-level directory in glibc, while sysdeps
files should go in the normal sysdeps directory structure (possibly in
hurd or hurd-pthreads subdirectories, just as there are nptl
subdirectories in the sysdeps tree).

Remove --with-fp / --without-fp.
There is a configure option --without-fp that specifies that nofpu
sysdeps directories should be used instead of fpu directories.
For most glibc configurations, this option is of no use: either there
is no valid nofpu variant of that configuration, or there are no fpu
or nofpu sysdeps directories for that processor and so the option does
nothing. For a few configurations, if you are using a soft-float
compiler this option is required, and failing to use it generally
results in compilation errors from inline asm using unavailable
floating-point instructions.
We're moving away from --with-cpu to configuring glibc based on how
the compiler generates code, and it is natural to do so for
--without-fp as well; in most cases the soft-float and hard-float ABIs
are incompatible so you have no hope of building a working glibc with
an inappropriately configured compiler or libgcc.
This patch eliminates --without-fp, replacing it entirely by automatic
configuration based on the compiler. Configurations for which this is
relevant (coldfire / mips / powerpc32 / sh) define a variable
with_fp_cond in their preconfigure fragments (under the same
conditions under which those fragments do anything); this is a
preprocessor conditional which the toplevel configure script then uses
in a test to determine which sysdeps directories to use.
The config.make with-fp variable remains. It's used only by powerpc
(sysdeps/powerpc/powerpc32/Makefile) to add -mhard-float to various
flags variables. For powerpc, -mcpu= options can imply use of
soft-float. That could be an issue if you want to build for
e.g. 476fp, but are using --with-cpu=476 because there isn't a 476fp
sysdeps directory. If in future we eliminate --with-cpu and replace
it entirely by testing the compiler, it would be natural at that point
to eliminate that code as well (as the user should then just use a
compiler defaulting to 476fp and the 476 sysdeps directory would be
used automatically).
Tested for x86_64, and tested with build-many-glibcs.py that installed
shared libraries are unchanged by this patch.

Obsolete p_secstodate.
This patch, relative to a tree with
<https://sourceware.org/ml/libc-alpha/2017-11/msg00797.html> (pending
review) applied, obsoletes p_secstodate, making the underlying
function __p_secstodate into a compat symbol not available for new
binaries or ports. The calls in ns_print.c (part of incomplete
handling of TKEY) are changed to use %lu to print times instead of
trying to pretty-print the times any more.
Tested for x86_64.
* resolv/res_debug.c (p_secstodate): Condition definition on
[SHLIB_COMPAT (libresolv, GLIBC_2_0, GLIBC_2_27)]. Define
directly as __p_secstodate, and as a compat symbol. Do not use
libresolv_hidden_def.
* resolv/resolv.h (p_secstodate): Remove macro and function
declaration.
* resolv/ns_print.c (ns_sprintrrf): Print times with %lu, not
using p_secstodate.
* include/resolv.h (__p_secstodate): Do not use
libresolv_hidden_proto.
* resolv/Makefile (tests): Move tst-p_secstodate to ....

* resolv/tst-p_secstodate.c: Include <shlib-compat.h>. Condition
all contents on [TEST_COMPAT (libresolv, GLIBC_2_0, GLIBC_2_27)]
and declare and use __p_secstodate and use compat_symbol_reference
in that case.
[!TEST_COMPAT (libresolv, GLIBC_2_0, GLIBC_2_27)] (do_test): Add
implementation returning 77.

Deprecate external use of libio.h and _G_config.h.
libio.h was originally the header for a set of supported GNU
extensions, but they have not been maintained as such in many years,
they are now standing in the way of improvements to stdio, and we
don't think there are any remaining external users. _G_config.h was
never intended for public use, but predates the bits convention.
Move both of these headers into the bits directory and provide stubs
at top level which issue deprecation warnings.
The contents of (bits/)libio.h and (bits/)_G_config.h are still
exposed to external software via stdio.h; changing that requires more
complex surgery than I have time to attempt right now.
* libio/libio.h, libio/_G_config.h: New stub headers which issue a
deprecation warning and then include <bits/libio.h>, <bits/_G_config.h>
respectively.
* libio/libio.h: Rename the original version of this file to
libio/bits/libio.h. Error out if not included by stdio.h or the
stub libio.h.
* include/libio.h: Move to include/bits. Forward to libio/bits/libio.h.
* sysdeps/generic/_G_config.h: Move to top-level bits/. Error out
if not included by bits/libio.h or the stub _G_config.h.
* sysdeps/unix/sysv/linux/_G_config.h: Move to
sysdeps/unix/sysv/linux/bits. Error out if not included by
bits/libio.h or the stub _G_config.h.
* libio/stdio.h: Include bits/libio.h, not libio.h.
* libio/Makefile: Install bits/libio.h and bits/_G_config.h as
well as libio.h and _G_config.h.
* csu/init.c, libio/fmemopen.c, libio/iolibio.h, libio/oldfmemopen.c
* libio/strfile.h, stdio-common/vfscanf.c
* sysdeps/pthread/flockfile.c, sysdeps/pthread/funlockfile.c
Include stdio.h, not _G_config.h nor libio.h.
* libio/iofgetpos.c: Also rename fgetpos64 out of the way.
* libio/iofsetpos.c: Also rename fsetpos64 out of the way.
* scripts/check-installed-headers.sh: Skip libio.h and _G_config.h.

|
|
|
* The nonstandard header files <libio.h> and <_G_config.h> are deprecated
|
|
|
|
|
|
and will be removed in a future release. Software that is still using
|
|
|
|
|
|
either header should be updated to use standard <stdio.h> interfaces
|
|
|
|
|
|
instead.

vulnerability; only trusted binaries must be examined using the ldd

Major new features:

|
|
|
|
|
2017-07-07 01:37:30 +08:00
|
|
|
|
* A per-thread cache has been added to malloc. Access to the cache requires
|
|
|
|
|
|
no locks and therefore significantly accelerates the fast path to allocate
|
|
|
|
|
|
and free small amounts of memory. Refilling an empty cache requires locking
|
|
|
|
|
|
the underlying arena. Performance measurements show significant gains in a
|
|
|
|
|
|
wide variety of user workloads. Workloads were captured using a special
|
|
|
|
|
|
instrumented malloc and analyzed with a malloc simulator. Contributed by
|
|
|
|
|
|
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.

|
|
|
|
* Unicode 10.0.0 Support: Character encoding, character type info, and
|
|
|
|
|
|
transliteration tables are all updated to Unicode 10.0.0, using
|
2017-02-21 19:30:38 +08:00
|
|
|
|
generator scripts contributed by Mike FABIAN (Red Hat).
|
2017-07-26 14:15:01 +08:00
|
|
|
|
These updates cause user visible changes, especially the changes in
|
|
|
|
|
|
wcwidth for many emoji characters cause problems when emoji sequences
|
|
|
|
|
|
are rendered with pango, see for example:

|
|
|
|
|
2017-07-05 21:46:57 +08:00
|
|
|
|
- The GNU C Library will now detect when /etc/resolv.conf has been
|
|
|
|
|
|
modified and reload the changed configuration. The new resolver option
|
|
|
|
|
|
“no-reload” (RES_NORELOAD) disables this behavior.
|
2017-04-21 21:40:56 +08:00
|
|
|
|
|
2017-07-05 21:46:57 +08:00
|
|
|
|
- The GNU C Library now supports an arbitrary number of search domains
|
|
|
|
|
|
(configured using the “search” directive in /etc/resolv.conf);
|
|
|
|
|
|
previously, there was a hard limit of six domains. For backward
|
|
|
|
|
|
compatibility, applications that directly modify the ‘_res’ global
|
|
|
|
|
|
object are still limited to six search domains.
|

|
|
|
|
|
2017-07-05 21:46:57 +08:00
|
|
|
|
- When the “rotate” (RES_ROTATE) resolver option is active, the GNU C
|
|
|
|
|
|
Library will now randomly pick a name server from the configuration as a
|
|
|
|
|
|
starting point. (Previously, the second name server was always used.)
|
2017-05-08 20:59:21 +08:00
|
|
|
|
|
2017-07-05 21:03:00 +08:00
|
|
|
|
* The tunables feature is now enabled by default. This allows users to tweak
|
|
|
|
|
|
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
|
2017-06-20 20:31:18 +08:00
|
|
|
|
|
2017-07-05 21:03:00 +08:00
|
|
|
|
* New function reallocarray, which resizes an allocated block (like realloc)
|
|
|
|
|
|
to the product of two sizes, with a guaranteed clean failure upon integer
|
|
|
|
|
|
overflow in the multiplication. Originally from OpenBSD, contributed by
|
|
|
|
|
|
Dennis Wölfing and Rüdiger Sonderfeld.

Rename xlocale.h to bits/types/__locale_t.h.
xlocale.h is already a single-type micro-header, defining struct
__locale_struct and the typedefs __locale_t and locale_t. This patch
brings it into the bits/types/ scheme: there are now
bits/types/__locale_t.h which defines only __locale_struct and
__locale_t, and bits/types/locale_t.h which defines locale_t as well
as the other two. None of *our* headers need __locale_t.h, but it
appears to me that libstdc++ could make use of it.
There are a lot of external uses of xlocale.h, but all the uses I
checked had an autoconf test or equivalent for its existence. It has
never been available from other C libraries, and it has always
contained a comment reading "This file is not standardized, don't rely
on it, it can go away without warning" so I think dropping it is
pretty safe.
I also took the opportunity to clean up comments in various public
header files that still talk about the *_l interfaces as though they
were completely nonstandard. There are a few of them, notably the
strtoX_l and wcstoX_l families, that haven't been standardized, but
the bulk are in POSIX.1-2008.
* locale/xlocale.h: Rename to...
* locale/bits/types/__locale_t.h: ...here. Adjust commentary.
Only define struct __locale_struct and __locale_t, not locale_t.
* locale/bits/types/locale_t.h: New file; define locale_t here.
* locale/Makefile (headers): Update to match.
* include/xlocale.h: Delete wrapper.
* include/bits/types/__locale_t.h: New wrapper.
* include/bits/types/locale_t.h: New wrapper.
* ctype/ctype.h, include/printf.h, include/time.h
* locale/langinfo.h, locale/locale.h, stdlib/monetary.h
* stdlib/stdlib.h, string/string.h, string/strings.h, time/time.h
* wcsmbs/wchar.h, wctype/wctype.h: Use bits/types/locale_t.h.
Correct outdated comments regarding the standardization status of
the functions that take locale_t arguments.
* stdlib/strtod_l.c, stdlib/strtof_l.c, stdlib/strtol_l.c
* stdlib/strtold_l.c, stdlib/strtoul_l.c, stdlib/strtoull_l.c
* sysdeps/ieee754/ldbl-128ibm/strtold_l.c
* sysdeps/ieee754/ldbl-64-128/strtold_l.c
* wcsmbs/wcstod.c, wcsmbs/wcstod_l.c, wcsmbs/wcstof.c
* wcsmbs/wcstof_l.c, wcsmbs/wcstold.c, wcsmbs/wcstold_l.c:
Don't include xlocale.h. If necessary, include locale.h instead.
* stdlib/strtold_l.c: Unconditionally include wchar.h.

* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
|
|
|
|
|
|
These are extended versions of preadv and pwritev, respectively, taking an
|
|
|
|
|
|
additional flags argument. The set of supported flags depends on the
|
|
|
|
|
|
running kernel; full support currently requires kernel 4.7 or later.
|
Factor out shared definitions from bits/signum.h.
Many of the things defined by bits/signum.h are invariant across all
supported operating systems. This patch factors out all of them to a
new header bits/signum-generic.h, which each bits/signum.h will include
and then override whichever things need adjustment. Normally that will
mean, at most, adding or changing a few signal numbers.
A user-visible side effect is that the obsolete signal constant SIGUNUSED
(which is an alias for SIGSYS on all platforms that define it) is no
longer exposed by any version of bits/signum.h.
A side effect only relevant to glibc hackers is that _NSIG is now defined
in terms of __SIGRTMAX, instead of the other way around. This is because
__SIGRTMAX varies from platform to platform, but _NSIG==__SIGRTMAX+1 is
true universally. If your platform doesn't support realtime signals,
leave __SIGRTMAX equal to __SIGRTMIN.
I also added a Linux-specific test to make sure that our signal constants
match the ones in <asm/signal.h>, since we can't use that header (it's
not even vaguely namespace-clean).
* bits/signum-generic.h: Renamed from bits/signum.h.
Add proper multiple include guard and misuse check.
Define __SIGRTMIN = __SIGRTMAX = 32, and define _NSIG = __SIGRTMAX+1.
Move definition of SIGIO to "archaic names for compatibility" section.
* bits/signum.h: New file which just includes bits/signum-generic.h.
* sysdeps/unix/bsd/bits/signum.h
* sysdeps/unix/sysv/linux/bits/signum.h
* sysdeps/unix/sysv/linux/alpha/bits/signum.h
* sysdeps/unix/sysv/linux/hppa/bits/signum.h
* sysdeps/unix/sysv/linux/mips/bits/signum.h
* sysdeps/unix/sysv/linux/sparc/bits/signum.h
Just include <bits/signum-generic.h> and then add or adjust
signal constants. Do not define SIGUNUSED, SIGRTMIN, or SIGRTMAX.
* signal/Makefile: Install bits/signum-generic.h.
* signal/signal.h: Define SIGRTMIN and SIGRTMAX here.
* sysdeps/generic/siglist.h: SIGSYS and SIGWINCH are
universal. Prefer SIGPOLL to SIGIO. Simplify #ifdeffage.
* sysdeps/unix/sysv/linux/tst-signal-numbers.sh: New test.
* sysdeps/unix/sysv/linux/Makefile: Run it.

2017-07-05 21:03:00 +08:00
|
|
|
|
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
|
|
|
|
|
|
create a new session ID for the spawned process. This feature is
|
|
|
|
|
|
scheduled to be added to the next major revision of POSIX; for the time
|
|
|
|
|
|
being, it is available under _GNU_SOURCE.

|
|
|
2017-07-05 21:03:00 +08:00
|
|
|
|
* errno.h is now safe to use from C-preprocessed assembly language on all
|
|
|
|
|
|
supported operating systems. In this context, it will only define the
|
|
|
|
|
|
Exxxx constants, as preprocessor macros expanding to integer literals.

* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
|
2017-07-06 01:43:58 +08:00
|
|
|
|
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
|
|
|
|
|
|
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
|
|

|
|
|
|
To compile programs that use this feature, the compiler must support
|
2017-07-06 01:43:58 +08:00
|
|
|
|
128-bit floating point with the type name _Float128 (as defined by TS
|
|
|
|
|
|
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
|
|
|
|
|
|
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
|
|
|
|
|
|
must be defined to make the new interfaces visible.
|
|
|
|
|
|
|
|
|
|
|
|
The new functions and macros correspond to those present for other
|
|
|
|
|
|
floating-point types (except for a few obsolescent interfaces not
|
|
|
|
|
|
supported for the new type), with F128 or f128 suffixes; for example,
|
|
|
|
|
|
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
|
|
|
|
|
|
printf or scanf formats for the new type; the strfromf128 and strtof128
|
|
|
|
|
|
interfaces should be used instead.

Deprecated and removed features, and other changes affecting compatibility:
|
|
|
|
|
|
|
|
|
|
|
|
* The synchronization that pthread_spin_unlock performs has been changed to
|
|
|
|
|
|
now be equivalent to a C11 atomic store with release memory order to the
|
|
|
|
|
|
spin lock's memory location. Previously, several (but not all)
|
|
|
|
|
|
architectures used stronger synchronization (e.g., containing what is
|
|
|
|
|
|
often called a full barrier). This change can improve performance, but
|
|
|
|
|
|
may affect odd fringe uses of spin locks that depend on the previous
|
|
|
|
|
|
behavior (e.g., using spin locks as atomic variables to try to implement
|
|
|
|
|
|
Dekker's mutual exclusion algorithm).
|
|
|
|
|
|
|
|
|
|
|
|
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
|
|
|
|
|
|
removed.
|
|
|
|
|
|
|
|
|
|
|
|
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
|
2017-07-05 21:46:57 +08:00
|
|
|
|
will only be built and installed when the GNU C Library is configured with
|
2017-07-05 21:03:00 +08:00
|
|
|
|
--enable-obsolete-rpc. This allows alternative RPC implementations, such
|
|
|
|
|
|
as TIRPC or rpcsvc-proto, to be used.
|
|
|
|
|
|
|
|
|
|
|
|
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
|
|
|
|
|
|
libnss_compat, are deprecated, and will not be built or installed by
|
|
|
|
|
|
default.
|
|
|
|
|
|
|
|
|
|
|
|
The NIS(+) support library, libnsl, is also deprecated. By default, a
|
|
|
|
|
|
compatibility shared library will be built and installed, but not headers
|
|
|
|
|
|
or development libraries. Only a few NIS-related programs require this
|
2017-07-05 21:46:57 +08:00
|
|
|
|
library. (In particular, the GNU C Library has never required programs
|
|
|
|
|
|
that use 'gethostbyname' to be linked with libnsl.)
|
2017-07-05 21:03:00 +08:00
|
|
|
|
|
|
|
|
|
|
Replacement implementations based on TIRPC, which additionally support
|
|
|
|
|
|
IPv6, are available from <https://github.com/thkukuk/>. The configure
|
|
|
|
|
|
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
|
|
|
|
|
|
name service modules, to be built and installed.
|
|
|
|
|
|
|
|
|
|
|
|
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
|
|
|
|
|
|
support is enabled, the configured recursive resolver must support EDNS.
|
|
|
|
|
|
(Responding to EDNS-enabled queries with responses which are not
|
|
|
|
|
|
EDNS-enabled is fine, but FORMERR responses are not.)
|
|
|
|
|
|
|
|
|
|
|
|
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
|
|
|
|
|
|
servers have not supported this opcode for a long time.
|
2017-06-30 16:43:33 +08:00
|
|
|
|
|
2017-06-30 17:31:41 +08:00
|
|
|
|
* The _res_opcodes variable has been removed from libresolv. It had been
|
|
|
|
|
|
exported by accident.
|
|
|
|
|
|
|
2017-07-05 21:03:00 +08:00
|
|
|
|
* <string.h> no longer includes inline versions of any string functions,
|
|
|
|
|
|
as this kind of optimization is better done by the compiler. The macros
|
|
|
|
|
|
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
|
|
|
|
|
|
|
|
|
|
|
|
* The nonstandard header <xlocale.h> has been removed. Most programs should
|
|
|
|
|
|
use <locale.h> instead. If you have a specific need for the definition of
|
|
|
|
|
|
locale_t with no other declarations, please contact
|
|
|
|
|
|
libc-alpha@sourceware.org and explain.
|
|
|
|
|
|
|
|
|
|
|
|
* The obsolete header <sys/ultrasound.h> has been removed.
|
|
|
|
|
|
|
|
|
|
|
|
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
|
|
|
|
|
|
|
|
|
|
|
|
* The obsolete function cfree has been removed. Applications should use
|
|
|
|
|
|
free instead.
|
|
|
|
|
|
|
|
|
|
|
|
* The stack_t type no longer has the name struct sigaltstack. This changes
|
|
|
|
|
|
the C++ name mangling for interfaces involving this type.
|
|
|
|
|
|
|
|
|
|
|
|
* The ucontext_t type no longer has the name struct ucontext. This changes
|
|
|
|
|
|
the C++ name mangling for interfaces involving this type.
|
|
|
|
|
|
|
|
|
|
|
|
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
|
|
|
|
|
|
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
|
|
|
|
|
|
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
|
|
|
|
|
|
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
|
|
|
|
|
|
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
|
|
|
|
|
|
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
|
|
|
|
|
|
fpregset_t type no longer has the name struct fpu. This changes the C++
|
|
|
|
|
|
name mangling for interfaces involving those types.
|
|
|
|
|
|
|
|
|
|
|
|
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
|
|
|
|
|
|
synced with the kernel:
|
|
|
|
|
|
|
|
|
|
|
|
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
|
|
|
|
|
|
are not supported on this architecture and have been removed.
|
|
|
|
|
|
|
|
|
|
|
|
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
|
|
|
|
|
|
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
|
|
|
|
|
|
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
|
|
|
|
|
|
|
|
|
|
|
|
Programs that assume the GET/SETREGS ptrace requests are universally
|
|
|
|
|
|
available will now fail to build, instead of malfunctioning at runtime.
|
|
|
|
|
|
|
|
|
|
|
|
Changes to build and runtime requirements:
|
|
|
|
|
|
|
|
|
|
|
|
* Linux kernel 3.2 or later is required at runtime, on all architectures
|
|
|
|

2017-07-05 21:46:57 +08:00

compiling programs that use the GNU C Library. (We do not know exactly
|

how old, and some GNU extensions to C may be _de facto_ required. If you
|
|
|
|
|
|
are interested in helping us make this statement less vague, please

|
|
|
|
|
|
2017-04-13 19:09:38 +08:00
|
|
|
|
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
|
2017-08-02 10:37:16 +08:00
|
|
|
|
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
|
|
|
|
|
|
|
|
|
|
|
|
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
|
|
|
|
|
|
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
|
|
|
|
|
|
|
|
|
|
|
|
* Avoid printing a backtrace from the __stack_chk_fail function since it is
|
|
|
|
|
|
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
|
|
|
|
|
|
(CVE-2010-3192).
|
|
|
|
|
|
|
|
|
|
|
|
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
|
|
|
|
|
|
fixed (CVE-2017-12133).

Support __STDC_WANT_LIB_EXT2__ feature test macro.
This patch implements support for the __STDC_WANT_LIB_EXT2__ feature
test macro from ISO/IEC TR 24731-2:2010, thereby implementing one
possible approach for supporting ISO C feature test macros.
Recall that, as described in
<https://sourceware.org/ml/libc-alpha/2016-05/msg00486.html>, these
macros work based on the definition when affected headers are
included, so cannot be handled once when the first system header is
included because that might not be one of the headers the particular
macro in question affects.
<https://sourceware.org/ml/libc-alpha/2016-05/msg00680.html> expresses
views on possible approaches for implementation and
<https://sourceware.org/ml/libc-alpha/2016-06/msg00039.html> follows
up on that.
This patch arranges things so that the relevant condition is
__GLIBC_USE (LIB_EXT2), following one of the suggestions given.
Headers using these macros include <bits/libc-header-start.h>, which
in turn includes <features.h>. Headers must define
__GLIBC_INTERNAL_STARTING_HEADER_IMPLEMENTATION before including
<bits/libc-header-start.h>, to discourage inclusion outside glibc as
requested. __USE_GNU conditions on affected functions are changed to
__GLIBC_USE (LIB_EXT2), while it's added as an additional alternative
on the conditions for functions already enabled for some POSIX
versions.
It would be possible to convert existing __USE_* conditionals to
__GLIBC_USE (with the relevant __GLIBC_USE_* being defined in
<features.h> where __USE_* are presently defined), and so make them
typo-proof (given -Wundef -Werror in glibc builds) because __GLIBC_USE
is used with #if not #ifdef / #if defined.
No attempt is made to enforce the rule about diagnosing different
definitions of __STDC_WANT_LIB_EXT2__ when affected headers are
included; such a diagnostic is incompatible with multiple-include
guards on the affected headers, unless compiler extensions are added
to support it.
As previously noted, glibc does not implement all features from TR
24731-2:2010: the functions aswprintf vaswprintf getwdelim getwline
are not in glibc, although they would be appropriate to add if someone
wished to do so. But I think it makes sense to support the feature
test macro if *any* of the controlled features are present in glibc.
Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

Make _REENTRANT and _THREAD_SAFE aliases for _POSIX_C_SOURCE=199506L.
For many years, the only effect of these macros has been to make
unistd.h declare getlogin_r. _POSIX_C_SOURCE >= 199506L also causes
this function to be declared. However, people who don't carefully
read all the headers might be confused into thinking they need to
define _REENTRANT for any threaded code (as was indeed the case a long
time ago).
Therefore, remove __USE_REENTRANT, and make _REENTRANT and _THREAD_SAFE
into synonyms for _POSIX_C_SOURCE=199506L. This will only affect
programs that don't select a higher conformance level some other way.
For instance, -std=c89 -D_REENTRANT will see a change in visible
declarations, but -std=c99 -D_POSIX_C_SOURCE=200809L -D_REENTRANT won't,
and -D_REENTRANT all by itself also won't, because _DEFAULT_SOURCE
implies _POSIX_C_SOURCE > 199506.
* include/features.h: Remove __USE_REENTRANT. Treat _REENTRANT
and _THREAD_SAFE the same as _POSIX_C_SOURCE=199506L, if a higher
POSIX conformance level has not been selected by other macros.
* NEWS, manual/creature.texi: Document this change.
* posix/unistd.h, posix/bits/unistd.h: Don't check __USE_REENTRANT.
* include/libc-symbols.h: Don't define _REENTRANT.
* scripts/check-installed-headers.sh: Don't undefine _REENTRANT.
2016-12-06 23:14:42 +08:00
|
|
|
|
* The nonstandard feature selection macros _REENTRANT and _THREAD_SAFE are
|
|
|
|
|
|
now treated as compatibility synonyms for _POSIX_C_SOURCE=199506L.
|
|
|
|
|
|
Since the GNU C Library defaults to a much newer revision of POSIX, this
|
|
|
|
|
|
will only affect programs that specifically request an old conformance
|
|
|
|
|
|
mode. For instance, a program compiled with -std=c89 -D_REENTRANT will
|
|
|
|
|
|
see a change in the visible declarations, but a program compiled with
|
|
|
|
|
|
just -D_REENTRANT, or -std=c99 -D_POSIX_C_SOURCE=200809L -D_REENTRANT,
|
|
|
|
|
|
will not.
|
|
|
|
|
|
|
|
|
|
|
|
Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
|
|
|
|
|
|
defined by all multithreaded code, but glibc has not required this for
|
|
|
|
|
|
many years.

* The inclusion of <sys/sysmacros.h> by <sys/types.h> is deprecated. This
|
|
|
|
|
|
means that in a future release, the macros “major”, “minor”, and “makedev”
|
|
|
|
|
|
will only be available from <sys/sysmacros.h>.
|
|
|
|
|
|
|
|
|
|
|
|
These macros are not part of POSIX nor XSI, and their names frequently
|
|
|
|
|
|
collide with user code; see for instance glibc bug 19239 and Red Hat bug
|
|
|
|
|
|
130601. <stdlib.h> includes <sys/types.h> under _GNU_SOURCE, and C++ code
|
|
|
|
|
|
presently cannot avoid being compiled under _GNU_SOURCE, exacerbating the
|
|
|
|
|
|
problem.

Add femode_t functions.
TS 18661-1 defines a type femode_t to represent the set of dynamic
floating-point control modes (such as the rounding mode and trap
enablement modes), and functions fegetmode and fesetmode to manipulate
those modes (without affecting other state such as the raised
exception flags) and a corresponding macro FE_DFL_MODE.
This patch series implements those interfaces for glibc. This first
patch adds the architecture-independent pieces, the x86 and x86_64
implementations, and the <bits/fenv.h> and ABI baseline updates for
all architectures so glibc keeps building and passing the ABI tests on
all architectures. Subsequent patches add the fegetmode and fesetmode
implementations for other architectures.
femode_t is generally an integer type - the same type as fenv_t, or as
the single element of fenv_t where fenv_t is a structure containing a
single integer (or the single relevant element, where it has elements
for both status and control registers) - except where architecture
properties or consistency with the fenv_t implementation indicate
otherwise. FE_DFL_MODE follows FE_DFL_ENV in whether it's a magic
pointer value (-1 cast to const femode_t *), a value that can be
distinguished from valid pointers by its high bits but otherwise
contains a representation of the desired register contents, or a
pointer to a constant variable (the powerpc case; __fe_dfl_mode is
added as an exported constant object, an alias to __fe_dfl_env).
Note that where architectures (that share a register between control
and status bits) gain definitions of new floating-point control or
status bits in future, the implementations of fesetmode for those
architectures may need updating (depending on whether the new bits are
control or status bits and what the implementation does with
previously unknown bits), just like existing implementations of
<fenv.h> functions that take care not to touch reserved bits may need
updating when the set of reserved bits changes. (As any new bits are
outside the scope of ISO C, that's just a quality-of-implementation
issue for supporting them, not a conformance issue.)
As with fenv_t, femode_t should properly include any software DFP
rounding mode (and for both fenv_t and femode_t I'd consider that
fragment of DFP support appropriate for inclusion in glibc even in the
absence of the rest of libdfp; hardware DFP rounding modes should
already be included if the definitions of which bits are status /
control bits are correct).
Tested for x86_64, x86, mips64 (hard float, and soft float to test the
fallback version), arm (hard float) and powerpc (hard float, soft
float and e500). Other architecture versions are untested.

exception flags without the side-effect of causing enabled traps to be
taken.
This patch series implements this function for glibc. The present
patch adds the fallback stub implementation, x86 and x86_64
implementations, documentation, tests and ABI baseline updates. The
remaining patches, some of them untested, add implementations for
other architectures. The implementations generally follow those of
the fesetexceptflag function.
As for fesetexceptflag, the approach taken for architectures where
setting flags causes enabled traps to be taken is to set the flags
(and potentially cause traps) rather than refusing to set the flags
and returning an error. Since ISO C and TS 18661 provide no way to
enable traps, this is formally in accordance with the standards.
The NEWS entry should be considered a placeholder, since this patch
series is intended to be followed by further such series adding other
TS 18661-1 features, so that the NEWS entry would end up looking more
like
* New <fenv.h> features from TS 18661-1:2014 are added to libm: the
fesetexcept, fetestexceptflag, fegetmode and fesetmode functions,
the femode_t type and the FE_DFL_MODE macro.
with hopefully more such entries for other features, rather than
having an entry for a single function in the end.
I believe we have consensus for adding TS 18661-1 interfaces as per
<https://sourceware.org/ml/libc-alpha/2016-06/msg00421.html>.

Add fromfp functions.
TS 18661-1 defines fromfp functions (fromfp, fromfpx, ufromfp,
ufromfpx, and float and long double variants) to convert from
floating-point to an integer type with any signedness and any given
width up to that of intmax_t, in any of the five IEEE rounding modes
(the usual four for binary floating point, plus rounding to nearest
with ties rounding away from zero), with control of whether in-range
non-integer values should result in the "inexact" exception being
raised. This patch implements these functions for glibc.
These implementations are (apart from raising exceptions) pure integer
implementations; it's entirely possible optimized versions could be
devised for some architectures. A common math/fromfp.h header
provides various common helper code that can readily be shared between
the implementations for different types. For each type, the bulk of
the implementation is also shared between the four functions, with
wrappers that define UNSIGNED and INEXACT macros appropriately before
including the main implementation.
As the functions return intmax_t and uintmax_t without math.h being
allowed to expose those typedef names, they are declared using
__intmax_t and __uintmax_t as obtained from <bits/types.h>.
The FP_INT_* rounding direction macros are defined as ascending
integers in the order the names are listed in the TS; I see no
significant value in allowing architectures to vary the values of
them.
The libm-test machinery is duly adapted to handle unsigned int
arguments, and intmax_t and uintmax_t results. Because each test
input is generally tested for four functions, five rounding modes and
several different widths, the libm-test.inc additions are very large.
Thus, the diffs in the body of this message exclude the libm-test.inc
changes, with the full patch being attached gzipped. The bulk of the
new tests were generated (expanded from a test input plus rounding
results and information about where it lies in the relevant interval
between integers, to libm-test tests for all relevant combinations of
function, rounding direction and width) by a script that's included in
the patch as math/gen-fromfp-tests.py (input data
math/gen-fromfp-tests-inputs); as an ad hoc script that's not really
expected to be rerun, it's not very polished, but it's at least
plausibly useful for adding any further tests for these functions in
future. I may split the libm-test tests up by function in future (so
both libm-test.inc and auto-libm-test-out are split into separate
files, and the tests for each function are also built and run
separately), but not for 2.25.
For no obvious reason, adding tgmath tests for the new functions
resulted in -Wuninitialized errors from test-tgmath.c about the
variable i being used uninitialized. Those errors were correct - the
variable is read by the frexp version in test-tgmath.c (where real
frexp would write through that pointer instead of reading it) - but I
don't know why this patch would result in the pre-existing issue being
newly detected. The patch initializes the variable to avoid those
errors.
With these changes, glibc 2.25 should have all the library features
from TS 18661-1 other than the functions that round result to narrower
type (and constant rounding directions, but I'm considering those
mainly a compiler feature not a library one).

Add roundeven, roundevenf, roundevenl.
TS 18661-1 defines roundeven functions that round a floating-point
number to the nearest integer, in that floating-point type, with ties
rounding to even (whereas the round functions round ties away from
zero). As with other such functions, they raise no exceptions apart
from "invalid" for signaling NaNs. There was a previous user request
for this functionality in glibc in
<https://sourceware.org/ml/libc-help/2015-02/msg00005.html>.
This patch implements these functions for glibc. The implementations
use integer bit-manipulation (or roundeven on the high and low parts,
in the IBM long double case). It's possible that there may be faster
approaches on some architectures (in particular, on AArch64 the frintn
instruction should do exactly what's required); I'll leave it to
architecture maintainers or others interested to implement such
architecture-specific versions if desired. (Where architectures have
instructions to round to nearest integer in the current rounding mode,
implementations saving and restoring the rounding mode - and dealing
with exceptions if those instructions generate "inexact" - are also
possible, though their performance depends on the cost of manipulating
exceptions / rounding mode state.)

Add llogb, llogbf, llogbl.
TS 18661-1 defines llogb functions that are like ilogb except that
they return long int instead of int. Corresponding FP_LLOGB* macros
are defined, whose values are required to have the obvious
correspondence to those of the FP_ILOGB* macros.
This patch implements these functions and macros for glibc. llogb
uses the type-generic infrastructure, with an implementation similar
to the wrapper for ilogb but with additional conversion from FP_ILOGB*
to FP_LLOGB*; this approach avoids needing to modify or duplicate any
of the architecture-specific ilogb implementations. Tests are also
based on those for ilogb.
Ideally the llogb functions would alias the ilogb ones when long is
32-bit, but such aliasing requires the associated header declarations
of the different-type alias to be hidden, typically by defining macros
before including the header (see e.g. how
sysdeps/ieee754/dbl-64/wordsize-64/s_llround.c defines lround to
__hidden_lround before including <math.h>). The infrastructure for
type-generic function implementations does not support defining such
macros at present (since C code can't define a macro whose name is
determined by other macros). So this patch leaves them as separate
functions (similar to e.g. scalbln and scalbn being separate in such a
case as well), but with the remapping of FP_ILOGB* to FP_LLOGB*
conditioned out in the case where it would be the identity map.

Add iseqsig.
TS 18661-1 adds an iseqsig type-generic comparison macro to <math.h>.
This macro is like the == operator except that unordered operands
result in the "invalid" exception and errno being set to EDOM.
This patch implements this macro for glibc. Given the need to set
errno, this is implemented with out-of-line functions __iseqsigf,
__iseqsig and __iseqsigl (of which the last only exists at all if long
double is ABI-distinct from double, so no function aliases or compat
support are needed). The present patch ignores excess precision
issues; I intend to deal with those in a followup patch. (Like
comparison operators, type-generic comparison macros should *not*
convert operands to their semantic types but should preserve excess
range and precision, meaning that for some argument types and values
of FLT_EVAL_METHOD, an underlying function should be called for a
wider type than that of the arguments.)
The underlying functions are implemented with the type-generic
template machinery. Comparing x <= y && x >= y is sufficient in ISO C
to achieve an equality comparison with "invalid" raised for unordered
operands (and the results of those two comparisons can also be used to
tell whether errno needs to be set). However, some architectures have
GCC bugs meaning that unordered comparison instructions are used
instead of ordered ones. Thus, a mechanism is provided for
architectures to use an explicit call to feraiseexcept to raise
exceptions if required. If your architecture has such a bug you
should add a fix-fp-int-compare-invalid.h header for it, with a
comment pointing to the relevant GCC bug report; if such a GCC bug is
fixed, that header's contents should have a __GNUC_PREREQ conditional
added so that the workaround can eventually be removed for that
architecture.
Tested for x86_64, x86, mips64, arm and powerpc.

Add iscanonical.
TS 18661-1 adds an iscanonical classification macro to <math.h>.
The motivation for this is decimal floating-point, where some values
have both canonical and noncanonical encodings. For IEEE binary
interchange formats, all encodings are canonical. For x86/m68k
ldbl-96, and for ldbl-128ibm, there are encodings that do not
represent any valid value of the type; although formally iscanonical
does not need to handle trap representations (and so could just always
return 1), it seems useful, and in line with the description in the TS
of "representations that are extraneous to the floating-point model"
as being non-canonical (as well as "redundant representations of some
or all of its values"), for it to detect those representations and
return 0 for them.
This patch adds iscanonical to glibc. It goes in a header
<bits/iscanonical.h>, included under appropriate conditions in
<math.h>. The default header version just evaluates the argument
(converted to its semantic type, though current GCC will probably
discard that conversion and any exceptions resulting from it) and
returns 1. ldbl-96 and ldbl-128ibm then have versions of the header
that call a function __iscanonicall for long double (the sizeof-based
tests will of course need updating for float128 support, like other
such type-generic macro implementations). The ldbl-96 version of
__iscanonicall has appropriate conditionals to reflect the differences
in the m68k version of that format (where the high mantissa bit may be
either 0 or 1 when the exponent is 0 or 0x7fff). Corresponding tests
for those formats are added as well. Other architectures do not have
any new functions added because just returning 1 is correct for all
their floating-point formats.
Tested for x86_64, x86, mips64 (to test the default macro version) and
powerpc.

Add totalorder, totalorderf, totalorderl.
TS 18661-1 defines totalorder functions implementing the totalOrder
comparison operation from IEEE 754-2008. This patch implements these
functions for glibc, including the type-generic macro in <tgmath.h>.
(The totalordermag functions will be added in a separate patch.)
The description of the totalOrder operation is complicated. However,
for IEEE interchange binary formats and the preferred quiet NaN
convention, what that complicated description means is that you
interpret the representation as a sign-magnitude integer (with -0
coming before +0) and do a <= comparison on that interpretation. For
finite values and infinities the ordering of the sign-magnitude
integers is just the same as the ordering of floating-point values, so
this extends that to all representations. (Different representations
of the same floating-point value - which includes same quantum in the
decimal case - must still be considered equal by this operation, but
that issue doesn't arise for IEEE interchange binary formats.) So the
complications are:
* When MIPS quiet NaN conventions are in use, the representation of
NaNs needs adjusting before making such an integer comparison. This
patch does this adjustment only when both arguments are NaNs, as
there's no need for it if only one is a NaN, and as long as both are
NaNs you can just flip the relevant bits without any problems from
this turning a NaN into an infinity.
* For the m68k version of ldbl-96, where the high mantissa bit is
"don't care" for infinities and NaNs, representations where it
differs must compare the same. Note: although the testcase for this
compiles, I have not actually tested on m68k.
* For ldbl-128ibm, the low part must be ignored when the high part is
NaN, and low parts of +0 and -0 must be considered the same whatever
the high part.
The new tests in libm-test.inc are the first tests there specifying
particular payloads for input NaNs. Separate tests are also added for
the ldbl-96 and ldbl-128ibm special cases where there are different
representations of the same value that must compare equal (which can't
be covered in libm-test.inc as that only specifies values, not
representations).

Add canonicalize, canonicalizef, canonicalizel.
TS 18661-1 defines canonicalize functions to produce a canonical
version of a floating-point representation. This patch implements
these functions for glibc.
As with the iscanonical macro, these functions are oriented to the
decimal floating-point case, where some values have both canonical and
noncanonical representations. However, the functions have a return
value that says whether they succeeded in storing a canonical result;
thus, they can fail for the case of an invalid representation (while
still not making any particular choice from among multiple equally
canonical valid representations of the same value). Since no
floating-point formats in glibc actually have noncanonical valid
representations, a type-generic implementation of these functions can
be used that expects iscanonical to return 0 only for invalid
representations. Now that iscanonical is used within libm.so,
libm_hidden_proto / libm_hidden_def are added for __iscanonicall.
The definition of these functions is intended to correspond to a
convertFormat operation to the same floating-point format. Thus, they
convert signaling NaNs to quiet NaNs, raising the "invalid" exception.
Such a conversion "should" produce "the canonical version of that
signaling NaN made quiet".
libm-test.inc is made to check NaN payloads for the output of these
functions, a new feature (at some point manipulation functions such as
fabs and copysign should have tests added that verify payload
preservation for them). As however some architectures may not follow
the recommended practice of preserving NaN payloads when converting a
signaling NaN to quiet, a new math-tests.h macro
SNAN_TESTS_PRESERVE_PAYLOAD is added, and defined to 0 for non-NAN2008
MIPS; any other architectures seeing test failures for lack of payload
preservation in this case should also define this macro to 0. (If any
cases arise where the sign isn't preserved either, those should have a
similar macro added.)
The ldbl-96 and ldbl-128ibm tests of iscanonical are renamed and
adapted to test canonicalizel as well on the same representations.

New string function explicit_bzero (from OpenBSD).
explicit_bzero(s, n) is the same as memset(s, 0, n), except that the
compiler is not allowed to delete a call to explicit_bzero even if the
memory pointed to by 's' is dead after the call. Right now, this effect
is achieved externally by having explicit_bzero be a function whose
semantics are unknown to the compiler, and internally, with a no-op
asm statement that clobbers memory. This does mean that small
explicit_bzero operations cannot be expanded inline as small memset
operations can, but on the other hand, small memset operations do get
deleted by the compiler. Hopefully full compiler support for
explicit_bzero will happen relatively soon.
There are two new tests: test-explicit_bzero.c verifies the
visible semantics in the same way as the existing test-bzero.c,
and tst-xbzero-opt.c verifies the not-being-optimized-out property.
The latter is conceptually based on a test written by Matthew Dempsky
for the OpenBSD regression suite.
The crypt() implementation has an immediate use for this new feature.
We avoid having to add a GLIBC_PRIVATE alias for explicit_bzero
by running all of libcrypt's calls through the fortified variant,
__explicit_bzero_chk, which is in the impl namespace anyway. Currently
I'm not aware of anything in libc proper that needs this, but the
glue is all in place if it does become necessary. The legacy DES
implementation wasn't bothering to clear its buffers, so I added that,
mostly for consistency's sake.

* The function explicit_bzero, from OpenBSD, has been added to libc. It is
|
|
|
|
|
|
intended to be used instead of memset() to erase sensitive data after use;
|
|
|
|
|
|
the compiler will not optimize out calls to explicit_bzero even if they
|
|
|
|
|
|
are "unnecessary" (in the sense that no _correct_ program can observe the
|
|
|
|
|
|
effects of the memory clear).

Fix default float_t definition (bug 20855).
The default (top-level) version of bits/mathdef.h defines float_t to
double. It is used on ColdFire, MicroBlaze, Nios II and SH3, all of
which define FLT_EVAL_METHOD to 0, so float_t should be float (and C11
requires a certain correspondence between these typedefs and
FLT_EVAL_METHOD values).
I proposed fixing this default in
<https://sourceware.org/ml/libc-alpha/2015-01/msg00499.html>, with no
objections from architecture maintainers, and this patch makes that
fix. As noted in the NEWS entry added, this might affect the ABIs of
non-glibc libraries (ImageMagick has been mentioned in gcc-patches
discussion of the S/390 case - which is unaffected by this patch), but
as noted in my previous message, affected libraries would have
problems with -mfpmath=sse anyway on 32-bit x86.
A (compilation) testcase is added to verify the required
correspondence of typedefs to FLT_EVAL_METHOD values. This test is
built with -fexcess-precision=standard to avoid any issues with GCC 7
on S/390 providing a more accurate FLT_EVAL_METHOD definition in the
default (no excess precision) mode. (This will also be usable to test
a fix for the recently reported bug about these typedefs on x86_64
-mfpmath=387, as architecture-specific tests can be added that
It is entirely possible that the fixed default makes some
architecture-specific versions of bits/mathdef.h semantically
equivalent to the default version and so no longer required. I don't
intend to investigate that separately from the refactoring I proposed
in <https://sourceware.org/ml/libc-alpha/2016-11/msg00745.html>, which
will create as few header variants as possible for each group of
definitions.
Tested (compilation only) with build-many-glibcs.py.
[BZ #20855]
* bits/mathdef.h (float_t): Define to float.
* math/test-flt-eval-method.c: New file.
* math/Makefile (tests): Add test-flt-eval-method.

2016-11-23 08:28:30 +08:00
|
|
|
|
* On ColdFire, MicroBlaze, Nios II and SH3, the float_t type is now defined
|
|
|
|
|
|
to float instead of double. This does not affect the ABI of any libraries
|
|
|
|
|
|
that are part of the GNU C Library, but may affect the ABI of other
|
|
|
|
|
|
libraries that use this type in their interfaces.

2016-11-24 05:30:04 +08:00

|
* On x86_64, when compiling with -mfpmath=387 or -mfpmath=sse+387, the
|
|
|
|
|
|
float_t and double_t types are now defined to long double instead of float
|
|
|
|
|
|
and double. These options are not the default, and this does not affect
|
|
|
|
|
|
the ABI of any libraries that are part of the GNU C Library, but it may
|
|
|
|
|
|
affect the ABI of other libraries that use this type in their interfaces,
|
|
|
|
|
|
if they are compiled or used with those options.

|
|
|
* The getentropy and getrandom functions, and the <sys/random.h> header file
|
|
|
|
|

have been added.

|
|
|
2016-11-30 21:59:27 +08:00
|
|
|
|
* The buffer size for byte-oriented stdio streams is now limited to 8192
|
|
|
|
|
|
bytes by default. Previously, on Linux, the default buffer size on most
|
|
|
|
|
|
file systems was 4096 bytes (and thus remains unchanged), except on
|
|
|
|
|
|
network file systems, where the buffer size was unpredictable and could be
|
|
|
|
|
|
as large as several megabytes.

2016-09-01 21:53:13 +08:00

|
|
|
* The <sys/quota.h> header now includes the <linux/quota.h> header. Support
|
|
|
|
|
|
for the Linux quota interface which predates kernel version 2.4.22 has
|
|
|
|
|
|
been removed.

|
|
|
2016-10-26 19:28:28 +08:00
|
|
|
|
* The malloc_get_state and malloc_set_state functions have been removed.
|
|
|
|
|
|
Already-existing binaries that dynamically link to these functions will
|
|
|
|
|
|
get a hidden implementation in which malloc_get_state is a stub. As far
|
|
|
|
|
|
as we know, these functions are used only by GNU Emacs and this change
|
|
|
|
|
|
will not adversely affect already-built Emacs executables. Any undumped
|
|
|
|
|
|
Emacs executables, which normally exist only during an Emacs build, should
|
|
|
|
|
|
be rebuilt by re-running “./configure; make” in the Emacs build tree.

2016-10-07 19:55:47 +08:00
|
|
|
|
* The “ip6-dotint” and “no-ip6-dotint” resolver options, and the
|
|
|
|
|
|
corresponding RES_NOIP6DOTINT flag from <resolv.h> have been removed.
|
|
|
|
|
|
“no-ip6-dotint” had already been the default, and support for the
|
|
|
|
|
|
“ip6-dotint” option was removed from the Internet in 2006.
|
|
|
|
|
|
|
2017-01-14 19:07:41 +08:00
|
|
|
|
* The "ip6-bytestring" resolver option and the corresponding RES_USEBSTRING
|
2016-10-07 19:43:48 +08:00
|
|
|
|
flag from <resolv.h> have been removed. The option relied on a
|
|
|
|
|
|
backwards-incompatible DNS extension which was never deployed on the
|
|
|
|
|
|
Internet.
|
|
|
|
|
|
|
2017-01-01 02:08:39 +08:00
|
|
|
|
* The flags RES_AAONLY, RES_PRIMARY, RES_NOCHECKNAME, RES_KEEPTSIG,
|
|
|
|
|
|
RES_BLAST defined in the <resolv.h> header file have been deprecated.
|
|
|
|
|
|
They were already unimplemented.

|

2016-10-04 17:52:10 +08:00
|
|
|
|
* The "inet6" option in /etc/resolv.conf and the RES_USE_INET6 flag for
|
|
|
|
|
|
_res.flags are deprecated. The flag was standardized in RFC 2133, but
|
|
|
|
|
|
removed again from the IETF name lookup interface specification in RFC
|
|
|
|
|
|
2553. Applications should use getaddrinfo instead.
|
|
|
|
|
|
|
2016-09-21 22:08:31 +08:00
|
|
|
|
* DNSSEC-related declarations and definitions have been removed from the
|
|
|
|
|
|
<arpa/nameser.h> header file, and libresolv will no longer attempt to
|
|
|
|
|
|
decode the data part of DNSSEC record types. Previous versions of glibc
|
|
|
|
|
|
only implemented minimal support for the previous version of DNSSEC, which
|
|
|
|
|
|
is incompatible with the currently deployed version.
|
|
|
|
|
|
|
2016-09-21 22:27:14 +08:00
|
|
|
|
* The resource record type classification macros ns_t_qt_p, ns_t_mrr_p,
|
|
|
|
|
|
ns_t_rr_p, ns_t_udp_p, ns_t_xfr_p have been removed from the
|
|
|
|
|
|
<arpa/nameser.h> header file because the distinction between RR types and
|
|
|
|
|
|
meta-RR types is not officially standardized, subject to revision, and
|
|
|
|
|
|
thus not suitable for encoding in a macro.
|
|
|
|
|
|
|
2016-09-21 22:30:27 +08:00
|
|
|
|
* The types res_sendhookact, res_send_qhook, re_send_rhook, and the qhook
|
|
|
|
|
|
and rhook members of the res_state type in <resolv.h> have been removed.
|
|
|
|
|
|
The glibc stub resolver did not support these hooks, but the header file
|
|
|
|
|
|
did not reflect that.
|
|
|
|
|
|
|
2016-10-07 15:56:46 +08:00
|
|
|
|
* For multi-arch support it is recommended to use a GCC which has
|
|
|
|
|
|
been built with support for GNU indirect functions. This ensures
|
|
|
|
|
|
that correct debugging information is generated for functions
|
|
|
|
|
|
selected by IFUNC resolvers. This support can either be enabled by
|
|
|
|
|
|
configuring GCC with '--enable-gnu-indirect-function', or by
|
|
|
|
|
|
enabling it by default by setting 'default_gnu_indirect_function'
|
|
|
|
|
|
variable for a particular architecture in the GCC source file
|
|
|
|
|
|
'gcc/config.gcc'.

Add pretty printers for the NPTL lock types
This patch adds pretty printers for the following NPTL types:
- pthread_mutex_t
- pthread_mutexattr_t
- pthread_cond_t
- pthread_condattr_t
- pthread_rwlock_t
- pthread_rwlockattr_t
To load the pretty printers into your gdb session, do the following:
python
import sys
sys.path.insert(0, '/path/to/glibc/build/nptl/pretty-printers')
end
source /path/to/glibc/source/pretty-printers/nptl-printers.py
You can check which printers are registered and enabled by issuing the
'info pretty-printer' gdb command. Printers should trigger automatically when
trying to print a variable of one of the types mentioned above.
The printers are architecture-independent, and were tested on an AMD64 running
Ubuntu 14.04 and an x86 VM running Fedora 24.
In order to work, the printers need to know the values of various flags that
are scattered throughout pthread.h and pthreadP.h as enums and #defines. Since
replicating these constants in the printers file itself would create a
maintenance burden, I wrote a script called gen-py-const.awk that Makerules uses
to extract the constants. This script is pretty much the same as gen-as-const.awk,
except it doesn't cast the constant values to 'long' and is thorougly documented.
The constants need only to be enumerated in a .pysym file, which is then referenced
by a Make variable called gen-py-const-headers.
As for the install directory, I discussed this with Mike Frysinger and Siddhesh
Poyarekar, and we agreed that it can be handled in a separate patch, and shouldn't
block merging of this one.
In addition, I've written a series of test cases for the pretty printers.
Each lock type (mutex, condvar and rwlock) has two test programs, one for itself
and other for its related 'attributes' object. Each test program in turn has a
PExpect-based Python script that drives gdb and compares its output to the
expected printer's. The tests run on the glibc host, which is assumed to have
both gdb and PExpect; if either is absent the tests will fail with code 77
(UNSUPPORTED). For cross-testing you should use cross-test-ssh.sh as test-wrapper.
I've tested the printers on both native builds and a cross build using a Beaglebone
Black running Debian, with the build system's filesystem shared with the board
through NFS.
Finally, I've written a README that explains all this and more.

* GDB pretty printers have been added for mutex and condition variable
|
|
|
|
|
|
structures in POSIX Threads. When installed and loaded in gdb these pretty
|
|
|
|
|
|
printers show various pthread variables in human-readable form when read
|
|
|
|
|
|
using the 'print' or 'display' commands in gdb.

* Tunables feature added to allow tweaking of the runtime for an application

|
|
|
|
|
program. This feature can be enabled with the '--enable-tunables' configure
|
|
|
|
|
|
flag. The GNU C Library manual has details on usage and README.tunables has
|
|
|
|
|
|
instructions on adding new tunables to the library.

2017-02-05 21:06:06 +08:00
|
|
|
|
* A new version of condition variables functions have been implemented in
|
|
|
|
|
|
the NPTL implementation of POSIX Threads to provide stronger ordering
|
|
|
|
|
|
guarantees.
|
|
|
|
|
|
|
|
|
|
|
|
* A new version of pthread_rwlock functions have been implemented to use a more
|
|
|
|
|
|
scalable algorithm primarily through not using a critical section anymore to
|
|
|
|
|
|
make state changes.

* The DNS stub resolver functions would crash due to a NULL pointer
|
|
|
|

dereference when processing a query with a valid DNS question type which

was used internally in the implementation. The stub resolver now uses a
|

question type which is outside the range of valid question type values.

Version 2.24
|
|
|
|
|
|
|
Require Linux 3.2 except on x86 / x86_64, 3.2 headers everywhere.
In <https://sourceware.org/ml/libc-alpha/2016-01/msg00885.html> I
proposed a minimum Linux kernel version of 3.2 for glibc 2.24, since
Linux 2.6.32 has reached EOL.
In the discussion in February, some concerns were expressed about
compatibility with OpenVZ containers. It's not clear that these are
real issues, given OpenVZ backporting kernel features and faking the
kernel version for guest software, as discussed in
<https://sourceware.org/ml/libc-alpha/2016-02/msg00278.html>. It's
also not clear that supporting running GNU/Linux distributions from
late 2016 (at the earliest) on a kernel series from 2009 is a sensible
expectation. However, as an interim step, this patch increases the
requirement everywhere except x86 / x86_64 (since the controversy was
only about those architectures); the special caveats and settings can
easily be removed later when we're ready to increase the requirements
on x86 / x86_64 (and if someone would like to raise the issue on LWN
as suggested in the previous discussion, that would be welcome). 3.2
kernel headers are required everywhere by this patch.
(x32 already requires 3.4 or later, so is unaffected by this patch.)
As usual for such a change, this patch only changes the configure
scripts and associated documentation. The intent is to follow up with
removal of dead __LINUX_KERNEL_VERSION conditionals. Each __ASSUME_*
or other macro that becomes dead can then be removed independently.
Tested for x86_64 and x86.

NSS: Implement group merging support.
https://sourceware.org/glibc/wiki/Proposals/GroupMerging
== Justification ==
It is common today for users to rely on centrally-managed user stores for
handling their user accounts. However, much software existing today does
not have an innate understanding of such accounts. Instead, they commonly
rely on membership in known groups for managing access-control (for
example the "wheel" group on Fedora and RHEL systems or the "adm" group
on Debian-derived systems). In the present incarnation of nsswitch, the
only way to have such groups managed by a remote user store such as
FreeIPA or Active Directory would be to manually remove the groups from
/etc/group on the clients so that nsswitch would then move past nss_files
and into the SSSD, nss-ldap or other remote user database.
== Solution ==
With this patch, a new action is introduced for nsswitch:
NSS_ACTION_MERGE. To take advantage of it, one will add [SUCCESS=merge]
between two database entries in the nsswitch.conf file. When a group is
located in the first of the two group entries, processing will continue
on to the next one. If the group is also found in the next entry (and the
group name and GID are an exact match), the member list of the second
entry will be added to the group object to be returned.
== Implementation ==
After each DL_LOOKUP_FN() returns, the next action is checked. If the
function returned NSS_STATUS_SUCCESS and the next action is
NSS_ACTION_MERGE, a copy of the result buffer is saved for the next pass
through the loop. If on this next pass through the loop the database
returns another instance of a group matching both the group name and GID,
the member list is added to the previous list and it is returned as a
single object. If the following database does not contain the same group,
then the original is copied back into the destination buffer.
This patch implements merge functionality only for the group database.
For other databases, there is a default implementation that will return
the EINVAL errno if a merge is requested. The merge functionality can be
implemented for other databases at a later time if such is needed. Each
database must provide a unique implementation of the deep-copy and merge
functions.
If [SUCCESS=merge] is present in nsswitch.conf for a glibc version that
does not support it, glibc will process results up until that operation,
at which time it will return results if it has found them or else will
simply return an error. In practical terms, this ends up behaving like
the remainder of the nsswitch.conf line does not exist.
== Iterators ==
This feature does not modify the iterator functionality from its current
behavior. If getgrnam() or getgrgid() is called, glibc will iterate
through all entries in the `group` line in nsswitch.conf and display the
list of members without attempting to merge them. This is consistent with
the behavior of nss_files where if two separate lines are specified for
the same group in /etc/groups, getgrnam()/getgrgid() will display both.
Clients are already expected to handle this gracefully.
== No Premature Optimizations ==
The following is a list of places that might be eligible for
optimization, but were not overengineered for this initial contribution:
* Any situation where a merge may occur will result in one malloc() of
the same size as the input buffer.
* Any situation where a merge does occur will result in a second
malloc() to hold the list of pointers to member name strings.
* The list of members is simply concatenated together and is not tested
for uniqueness (which is identical to the behavior for nss_files,
which will simply return identical values if they both exist on the
line in the file. This could potentially be optimized to reduce space
usage in the buffer, but it is both complex and computationally
expensive to do so.
== Testing ==
I performed testing by running the getent utility against my newly-built
glibc and configuring /etc/nsswitch.conf with the following entry:
group: group: files [SUCCESS=merge] sss
In /etc/group I included the line:
wheel:x:10:sgallagh
I then configured my local SSSD using the id_provider=local to respond
with:
wheel:*:10:localuser,localuser2
I then ran `getent group wheel` against the newly-built glibc in
multiple situations and received the expected output as described
above:
* When SSSD was running.
* When SSSD was configured in nsswitch.conf but the daemon was not
running.
* When SSSD was configured in nsswitch.conf but nss_sss.so.2 was not
installed on the system.
* When the order of 'sss' and 'files' was reversed.
* All of the above with the [SUCCESS=merge] removed (to ensure no
regressions).
* All of the above with `getent group 10`.
* All of the above with `getent group` with and without
`enumerate=true` set in SSSD.
* All of the above with and without nscd enabled on the system.

|
|
|
|
* A new NSS action is added to facilitate large distributed system
|
|
|
|
|
|
administration. The action, MERGE, allows remote user stores like LDAP
|
|
|
|
|
|
to be merged into local user stores like /etc/groups in order to provide
|
|
|
|
|
|
easy to use, updated, and managed sets of merged credentials. The new
|
|
|
|
|
|
action can be used by configuring it in /etc/nsswitch.conf:
|
|
|
|
|
|
group: files [SUCCESS=merge] nis

* nextupl, nextup, nextupf, nextdownl, nextdown and nextdownf are added to
|
|
|
|
|
|
libm. They are defined by TS 18661 and IEEE754-2008. The nextup functions
|
|
|
|
|
|
return the next representable value in the direction of positive infinity
|
|
|
|
|
|
and the nextdown functions return the next representable value in the
|
|
|
|
|
|
direction of negative infinity. These are currently enabled as GNU
|
|
|
|

* An unnecessary stack copy in _nss_dns_getnetbyname_r was removed. It
|
|
|
|
|
|
could result in a stack overflow when getnetbyname was called with an
|
|

|
* Previously, getaddrinfo copied large amounts of address data to the stack,
|
|
|
|
|
|
even after the fix for CVE-2013-4458 has been applied, potentially
|
|
|
|
|
|
resulting in a stack overflow. getaddrinfo now uses a heap allocation
|
|
|
|
|
|
instead. Reported by Michael Petlan. (CVE-2016-3706)

* The IPv6 name server management code in libresolv could result in a memory
|
|
|
|
|
|
leak for each thread which is created, performs a failing naming lookup,
|
|
|
|
|
|
and exits. Over time, this could result in a denial of service due to

Remove CPU set size checking from affinity functions [BZ #19143]
With current kernel versions, the check does not reliably detect that
unavailable CPUs are requested, for these reasons:
(1) The kernel will silently ignore non-allowed CPUs, that is, CPUs
which are physically present but disallowed for the thread
based on system configuration.
(2) Similarly, CPU bits which lack an online CPU (possible CPUs)
are ignored.
(3) The existing probing code assumes that the CPU mask size is a
power of two and at least 1024. Neither has it to be a power
of two, nor is the minimum possible value 1024, so the value
determined is often too large. This means that the CPU set
size check in glibc accepts CPU bits beyond the actual hard
system limit.
(4) Future kernel versions may not even have a fixed CPU set size.
After the removal of the probing code, the kernel still returns
EINVAL if no CPU in the requested set remains which can run the
thread after the affinity change.
Applications which care about the exact affinity mask will have
to query it using sched_getaffinity after setting it. Due to the
effects described above, this commit does not change this.
The new tests supersede tst-getcpu, which is removed. This
addresses bug 19164 because the new tests allocate CPU sets
dynamically.

2015-11-25 00:21:01 +08:00
|
|
|
|
* sched_setaffinity, pthread_setaffinity_np no longer attempt to guess the
|
|
|
|
|
|
kernel-internal CPU set size. This means that requests that change the
|
|
|
|
|
|
CPU affinity which failed before (for example, an all-ones CPU mask) will
|
|
|
|
|
|
now succeed. Applications that need to determine the effective CPU
|
|
|
|
|
|
affinities need to call sched_getaffinity or pthread_getaffinity_np after
|
|
|
|
|
|
setting it because the kernel can adjust it (and the previous size check
|
|
|
|
|
|
would not detect this in the majority of cases).

Add LFS support for fts functions (bug 11460)
fts didn't have large-file support yet and fts.h had an #error preventing
usage when _FILE_OFFSET_BITS was set. This required nasty workarounds for
programs using fts with LFS. This patch implements LFS support for fts by
adding FTS64 and FTENT64 variants plus fts64 functions. Which are simple
aliases for 64bit off_t arches.
Also includes a simple testcase for some of the fts functions with or
without LFS enabled.

S390: Optimize string, wcsmbs and memory functions.
This patch set introduces optimized string, wcsmbs and memory functions for
S390/S390x. The functions are accelerated by the usage of the new z13 vector
instructions.
The Principles of Operations manual for IBM z13 is publically available:
http://publibfi.boulder.ibm.com/epubs/pdf/dz9zr010.pdf
The support for these instructions in assembler was introduced by commits:
-"[Committed] S/390: Add support for IBM z13."
(https://sourceware.org/ml/binutils/2015-01/msg00197.html)
-"[Committed] S/390: Add more IBM z13 instructions"
(https://sourceware.org/ml/binutils/2015-03/msg00088.html)
The first patches do preparation for the latter optimization patches.
The floating point exception handling - fetestexcept(), ... - is fixed and
the platform and hwcap strings are extended.
The current ifunc routines memset, memcpy and memcmp are refactored and the
ifunc test-framework is now enabled.
A S390 specific configure-check tests if the used binutils supports the new
vector instructions. The optimized functions are provided via ifunc if the
binutils supports the vector instructions. Otherwise a message is dumped to
configure output and only the currently used common code functions are
available.
The optimized functions are implemented in common for s390-32 and s390-64
and the few differences are handled via #ifdef.
The ifunc-resolvers are defined in files sysdeps/s390/multiarch/<func>.c,
which choose either the current implementation __<func>_c() or the vector
implementation __<func>_vx() depending on the HWCAP_S390_VX flag bit in
AT_HWCAP field. If the bit is set, the hardware and the kernel are supporting
vector registers and instructions. If the used binutils lacks vector-support,
then the default implementation in string or wcsmbs directory is included
here instead.
The file sysdeps/s390/multiarch/<func>-c.c includes the current implementation
and defines the function name __<func>_c.
The assembler files sysdeps/s390/multiarch/<func>-vx.S with the vector
instructions are using the directive '.machine "z13"' to allow building glibc
without option '-march=z13'. Additionally the directive '.machinemode
"zarch_nohighgprs"' is needed for the 31bit glibc. This mode does not set the
highgprs flag in ELF header, which would lead to an unloadable libc on a 31bit
kernel.
The most optimized string functions are structured in the same way:
The first 16 bytes of the string is loaded unaligned via vlbb - vector load
to block boundary (e.g. 4k). This instruction loads 16 bytes if possible.
In case of a page cross, it only loads the last bytes of the current page
without a segmentation fault.
Afterwards these first part of string is processed. If e.g. for strlen the end
of string is reached within this first part, the function returns. Otherwise
the pointer is aligned to 16 byte, so i can load a full vector register with vl
without checking for a page cross. Afterwards the first part of string is
processed. If e.g. for strlen the end of string is reached within this first
part, the function returns. Otherwise the pointer is aligned to 16 byte, so
a full vector register can be loaded with vl - vector load - without checking
for a page cross. The remaining string is processed in a four times unrolled
loop, because benchmark results measured improvements compared to a non
unrolled loop.
The optimized wide string functions can only handle 4byte aligned string
pointers. Although a wchar_t pointer should always be 4byte aligned, the most
current common code wide string functions can handle non aligned strings.
Thus the optimized functions will fall back to the common code functions in
case of a non aligned wide string to behave the same as before this patch.
Some string tests can test the string and the wide string version of a function.
The remaining ones are extended and new wide string tests are added.
This is the same in case of the benchtests.

Make obsolete syscall wrappers into compat symbols (bug 18472).
Various Linux kernel syscalls have become obsolete over time.
Specifically, the following are obsolete in all kernel versions
supported by glibc, are not present for architectures more recently
added to the kernel, and as such, the wrapper functions for them
should be compat symbols, not in static libc and not available for new
links with shared libc.
* bdflush: in Linux 2.6, does nothing if present.
* create_module get_kernel_syms query_module: Linux 2.4 module
interface, syscalls not present in Linux 2.6.
* uselib: part of the mechanism for loading a.out shared libraries,
irrelevant with ELF.
This patch adds support for syscalls.list to list syscall aliases of
the form NAME@VERSION:OBSOLETED, with SHLIB_COMPAT conditionals being
generated for such aliases. Those five syscalls are then made into
compat symbols (obsoleted in glibc 2.23, so future ports won't have
these symbols at all), with the header <sys/kdaemon.h> declaring
bdflush being removed. When we move to 3.2 as minimum kernel version,
the same can be done for nfsservctl (removed in Linux 3.1) as well.
Tested for x86_64 and x86 (testsuite, as well as checking that the
symbols in question indeed become compat symbols, that they are indeed
omitted from static libc, and that the generated SHLIB_COMPAT
conditionals look right).
[BZ #18472]
* sysdeps/unix/Makefile ($(objpfx)stub-syscalls.c): Handle entries
for the form NAME@VERSION:OBSOLETED and generate SHLIB_COMPAT
conditionals for them.
* sysdeps/unix/make-syscalls.sh (emit_weak_aliases): Likewise.

Fix lgamma setting signgam for ISO C (bug 15421).
The lgamma (and likewise lgammaf, lgammal) function wrongly sets the
signgam variable even when building for strict ISO C conformance
(-std=c99 / -std=c11), although the user may define such a variable
and it's only in the implementation namespace for POSIX with XSI
extensions enabled.
Following discussions starting at
<https://sourceware.org/ml/libc-alpha/2013-04/msg00767.html> and
<https://sourceware.org/ml/libc-alpha/2015-10/msg00844.html>, it seems
that the safest approach for fixing this particular issue is for
signgam to become a weak alias for a newly exported symbol __signgam,
with the library functions only setting __signgam, at which point
static linker magic will preserve the alias for newly linked binaries
that refer to the library's signgam rather than defining their own,
while breaking the alias for programs that define their own signgam,
with new symbol versions for lgamma functions and with compat symbols
for existing binaries that set both signgam and __signgam.
This patch implements that approach for the fix. signgam is made into
a weak alias. The four symbols __signgam, lgamma, lgammaf, lgammal
get new symbol versions at version GLIBC_2.23, with the existing
versions of lgamma, lgammaf and lgammal becoming compat symbols.
When the compat versions are built, gamma, gammaf and gammal are
aliases for the compat versions (i.e. always set signgam); this is OK
as they are not ISO C functions, and avoids adding new symbol versions
for them unnecessarily. When the compat versions are not built
(i.e. for static linking and for future glibc ports), gamma, gammaf
and gammal are aliases for the new versions that set __signgam. The
ldbl-opt versions are updated accordingly.
The lgamma wrappers are adjusted so that the same source files,
included from different files with different definitions of
USE_AS_COMPAT, can build either the new versions or the compat
versions. Similar changes are made to the ia64 versions (untested).
Tests are added that the lgamma functions do not interfere with a user
variable called signgam for ISO C, with various choices for the size
of that variable, whether it is initialized, and for static and
dynamic linking. The conformtest whitelist entry is removed as well.
Tested for x86_64, x86, mips64 and powerpc, including looking at
objdump --dynamic-syms output to make sure the expected sets of
symbols were aliases. Also spot-tested that a binary built with old
glibc works properly (i.e. gets signgam set) when run with new glibc.

Fix nan functions handling of payload strings (bug 16961, bug 16962).
The nan, nanf and nanl functions handle payload strings by doing e.g.:
if (tagp[0] != '\0')
{
char buf[6 + strlen (tagp)];
sprintf (buf, "NAN(%s)", tagp);
return strtod (buf, NULL);
}
This is an unbounded stack allocation based on the length of the
argument. Furthermore, if the argument starts with an n-char-sequence
followed by ')', that n-char-sequence is wrongly treated as
significant for determining the payload of the resulting NaN, when ISO
C says the call should be equivalent to strtod ("NAN", NULL), without
being affected by that initial n-char-sequence. This patch fixes both
those problems by using the __strtod_nan etc. functions recently
factored out of strtod etc. for that purpose, with those functions
being exported from libc at version GLIBC_PRIVATE.
Tested for x86_64, x86, mips64 and powerpc.

Fix nan functions handling of payload strings (bug 16961, bug 16962).
The nan, nanf and nanl functions handle payload strings by doing e.g.:
if (tagp[0] != '\0')
{
char buf[6 + strlen (tagp)];
sprintf (buf, "NAN(%s)", tagp);
return strtod (buf, NULL);
}
This is an unbounded stack allocation based on the length of the
argument. Furthermore, if the argument starts with an n-char-sequence
followed by ')', that n-char-sequence is wrongly treated as
significant for determining the payload of the resulting NaN, when ISO
C says the call should be equivalent to strtod ("NAN", NULL), without
being affected by that initial n-char-sequence. This patch fixes both
those problems by using the __strtod_nan etc. functions recently
factored out of strtod etc. for that purpose, with those functions
being exported from libc at version GLIBC_PRIVATE.
Tested for x86_64, x86, mips64 and powerpc.

* A stack-based buffer overflow was found in libresolv when invoked from
|
|
|
|
|
|
libnss_dns, allowing specially crafted DNS responses to seize control
|
|
|
|
|
|
of execution flow in the DNS client. The buffer overflow occurs in
|
|
|
|
|
|
the functions send_dg (send datagram) and send_vc (send TCP) for the
|
|
|
|
|
|
NSS module libnss_dns.so.2 when calling getaddrinfo with AF_UNSPEC
|
|
|
|
|
|
family. The use of AF_UNSPEC triggers the low-level resolver code to
|
|
|
|
|
|
send out two parallel queries for A and AAAA. A mismanagement of the
|
|
|
|
|
|
buffers used for those queries could result in the response of a query
|
|
|
|
|
|
writing beyond the alloca allocated buffer created by
|
|
|
|
|
|
_nss_dns_gethostbyname4_r. Buffer management is simplified to remove
|
|
|
|
|
|
the overflow. Thanks to the Google Security Team and Red Hat for
|
|
|
|
|
|
reporting the security impact of this issue, and Robert Holiday of
|

* A buffer overflow in gethostbyname_r and related functions performing DNS
|
|
|
|
|
|
requests has been fixed. If the NSS functions were called with a
|
|
|
|
|
|
misaligned buffer, the buffer length change due to pointer alignment was
|
|
|
|
|
|
not taken into account. This could result in application crashes or,
|
|
|
|
|
|
potentially arbitrary code execution, using crafted, but syntactically
|
|
|
|
|
|
valid DNS responses. (CVE-2015-1781)

* The time zone file parser has been made more robust against crafted time
|
|
|
|
|
|
zone files, avoiding heap buffer overflows related to the processing of
|
|
|

the tzh_ttisstdcnt and tzh_ttisgmtcnt fields, and a stack overflow due to
|
|
|
|
|
|
large time zone data files. Overly long time zone specifiers in the TZ
|
|
|
|
|
|
variable no longer result in stack overflows and crashes.

* A new fmemopen implementation has been added with the goal of POSIX
|
|
|
|
|
|
compliance. The new implementation fixes the following long-standing
|
|
|
|
|
|
issues: BZ#6544, BZ#11216, BZ#12836, BZ#13151, BZ#13152, and BZ#14292. The
|
|
|
|
|
|
old implementation is still present for use be by existing binaries.

* The 32-bit sparc sigaction ABI was inadvertently broken in the 2.20 and 2.21
|

|
releases. It has been fixed to match 2.19 and older, but binaries built
|
|
|
|
|
|
against 2.20 and 2.21 might need to be recompiled. See BZ#18694.

This header was formerly part of SUS, but was deprecated in 1994 and
|
2015-08-02 02:38:05 +08:00
|

* A new semaphore algorithm has been implemented in generic C code for all
|
|
|
|
|
|
machines. Previous custom assembly implementations of semaphore were
|
|
|
|
|
|
difficult to reason about or ensure that they were safe. The new version
|
|
|
|
|
|
of semaphore supports machines with 64-bit or 32-bit atomic operations.
|
|
|
|
|
|
The new semaphore algorithm is used by sem_init, sem_open, sem_post,
|
|
|
|
|
|
sem_wait, sem_timedwait, sem_trywait, and sem_getvalue.

* Added support for TSX lock elision of pthread mutexes on powerpc32, powerpc64
|
|
|

and powerpc64le. This may improve lock scaling of existing programs on
|
|
|
|
|

|
|
|
|
|
--enable-lock-elision=yes. Also, the TSX lock elision implementation for
|
|
|
|
|

|
|
|
|
effects being visible outside transactions.

* The minimum GCC version that can be used to build this version of the GNU
|
|
|

|
|
still be used to compile programs using the GNU C Library.

Use -Werror by default, add --disable-werror.
As discussed starting at
<https://sourceware.org/ml/libc-alpha/2014-11/msg00323.html>, this
patch makes the glibc build use -Werror by default to avoid
accidentally adding new warnings to the build. The configure option
--disable-werror can be used to disable this.
-Wno-error=undef is temporarily used because the build isn't clean
regarding -Wundef warnings. The idea is that once the remaining
-Wundef warnings have been cleaned up (in at least one configuration),
-Wno-error=undef will be removed.
I get a clean build and test on x86_64 (GCC 4.9 branch) with this
patch. The expectation is that this may well break the build for some
other configurations, and people seeing such breakage should make
appropriate fixes to fix or suppress the warnings for their
configurations. In some cases that may involve using pragmas as the
right fix (I think that will be right for the -Wno-inline issue for
MIPS I referred to in
<https://sourceware.org/ml/libc-alpha/2012-11/msg00798.html>, for
example), in some cases -Wno-error in sysdeps makefiles (__restore_rt
in MIPS sigaction, for example), in some cases substantive fixes for
the warnings.
Note that if, with a view to listing all the warnings then fixing them
all, you just look for "warning:" in output from building and testing
with --disable-werror, you'll see lots of warnings from the linker
about functions such as tmpnam. Those warnings can be ignored - only
compiler warnings are relevant to -Werror, not linker warnings.
* configure.ac (--disable-werror): New configure option.
(enable_werror): New AC_SUBST.
* configure: Regenerated.
* config.make.in (enable-werror): New variable.
* Makeconfig [$(enable-werror) = yes] (+gccwarn): Add -Werror
-Wno-error=undef.
(+gccwarn-c): Do not use -Werror=implicit-function-declaration.
* manual/install.texi (Configuring and compiling): Document
--disable-werror.
* INSTALL: Regenerated.
* debug/Makefile (CFLAGS-tst-chk1.c): Add -Wno-error.
(CFLAGS-tst-chk2.c): Likewise.

|
* The obsolete sigvec function has been removed. This was the original
|
|
|
|
|
|
4.2BSD interface that inspired the POSIX.1 sigaction interface, which
|
|
|
|
|
|
programs have been using instead for about 25 years. Of course, ABI
|
|
|
|
|
|
compatibility for old binaries using sigvec remains intact.

* Support for MIPS o32 FPXX, FP64A and FP64 ABI Extensions.
|
|
|
|
|
|
The original MIPS o32 hard-float ABI requires an FPU where double-precision
|
|
|
|
|
|
registers overlay two consecutive single-precision registers. MIPS32R2
|
|
|
|
|
|
introduced a new FPU mode (FR=1) where double-precision registers extend the
|
|
|
|
|
|
corresponding single-precision registers which is incompatible with the
|
|
|
|
|
|
o32 hard-float ABI. The MIPS SIMD ASE and the MIPSR6 architecture both
|
|
|
|
|
|
require the use of FR=1 making a transition necessary. New o32 ABI
|
|
|
|
|
|
extensions enable users to migrate over time from the original o32 ABI
|
|
|
|
|
|
through to the updated o32 FP64 ABI. To achieve this the dynamic linker now
|
|
|
|
|
|
tracks the ABI of any loaded object and verifies that new objects are
|
|
|
|
|
|
compatible. Mode transitions will also be requested as required and
|
|
|
|
|
|
unsupportable objects will be rejected. The ABI checks include both soft and
|
|
|
|
|
|
hard float ABIs for o32, n32 and n64.
|
|
|
|
|
|
|
|
|
|
|
|
GCC 5 with GNU binutils 2.25 onwards:
|
|
|
|
|
|
It is strongly recommended that all o32 system libraries are built using the
|
|
|
|
|
|
new o32 FPXX ABI (-mfpxx) to facilitate the transition as this is compatible
|
|
|
|
|
|
with the original and all new o32 ABI extensions. Configure a MIPS GCC
|
|
|
|
|
|
compiler using --with-fp-32=xx to set this by default.

* Reverted change of ABI data structures for s390 and s390x:
|
|
|
|
|
|
On s390 and s390x the size of struct ucontext and jmp_buf was increased in
|
|
|
|
|
|
2.19. This change is reverted in 2.20. The introduced 2.19 symbol versions
|
|
|
|
|
|
of getcontext, setjmp, _setjmp, __sigsetjmp, longjmp, _longjmp, siglongjmp
|
|
|
|
|
|
are preserved pointing straight to the same implementation as the old ones.
|
2014-08-27 23:53:25 +08:00
|
|
|
|
Given that, new callers will simply provide a too-big buffer to these
|
2014-08-01 15:48:17 +08:00
|
|
|
|
functions. Any applications/libraries out there that embed jmp_buf or
|
|
|
|
|
|
ucontext_t in an ABI-relevant data structure that have already been rebuilt
|
|
|
|
|
|
against 2.19 headers will have to rebuilt again. This is necessary in any
|
|
|
|
|
|
case to revert the breakage in their ABI caused by the glibc change.
|
|

* Support for file description locks is added to systems running the
|
|
|
|
|
|
Linux kernel. The standard file locking interfaces are extended to
|
|
|
|
|
|
operate on file descriptions, not file descriptors, via the use of
|
|
|
|
|
|
F_OFD_GETLK, F_OFD_SETLK, and F_OFD_SETLKW. File description locks
|
|
|
|
|
|
are associated with an open file instead of a process.

Do not terminate default test runs on test failure.
This patch is an updated version of
<https://sourceware.org/ml/libc-alpha/2014-01/msg00198.html> and
<https://sourceware.org/ml/libc-alpha/2014-03/msg00180.html>.
Normal practice for software testsuites is that rather than
terminating immediately when a test fails, they continue running and
report at the end on how many tests passed or failed.
The principle behind the glibc testsuite stopping on failure was
probably that the expected state is no failures and so any failure
indicates a problem such as miscompilation. In practice, while this
is fairly close to true for native testing on x86_64 and x86 (kernel
bugs and race conditions can still cause intermittent failures), it's
less likely to be the case on other platforms, and so people testing
glibc run the testsuite with "make -k" and then examine the logs to
determine whether the failures are what they expect to fail on that
platform, possibly with some automation for the comparison.
This patch switches the glibc testsuite to the normal convention of
not stopping on failure - unless you use stop-on-test-failure=y, in
which case it behaves essentially as it did before (and does not
generate overall test summaries on failure). Instead, the summary
tests.sum may contain tests that FAILed. At the end of the test run,
any FAIL or ERROR lines from tests.sum are printed, and then it exits
with error status if there were any such lines. In addition, build
failures will also cause the test run to stop - this has the
justification that those *do* indicate serious problems that should be
promptly fixed and aren't generally hard to fix (but apart from that,
avoiding the build stopping on those failures seems harder).
Note that unlike the previous patches in this series, this *does*
require people with automation around testing glibc to change their
processes - either to start using tests.sum / xtests.sum to track
failures and compare them with expectations (with or without also
using "make -k" and examining "make" logs to identify build failures),
or else to use stop-on-test-failure=y and ignore the new tests.sum /
xtests.sum mechanism. (If all you check is the exit status from "make
check", no changes are needed unless you want to avoid test runs
continuing after the first failure.)
Tested x86_64.
* scripts/evaluate-test.sh: Handle fourth argument to determine
whether test run should stop on failure.
* Makeconfig (stop-on-test-failure): New variable.
(evaluate-test): Pass fourth argument to evaluate-test.sh based on
$(stop-on-test-failure).
* Makefile (tests): Give a summary of results from testing and
exit with failure status if they include an ERROR or FAIL.
(xtests): Likewise.
* manual/install.texi (Configuring and compiling): Mention
stop-on-test-failure=y.
* INSTALL: Regenerated.

|
|
|
|
* Running the testsuite no longer terminates as soon as a test fails.
|
|
|
|
|
|
Instead, a file tests.sum (xtests.sum from "make xcheck") is generated,
|
|
|
|
|
|
with PASS or FAIL lines for individual tests. A summary of the results is
|
|
|
|
|
|
printed, including a list of failing lists, and "make check" exits with
|
|
|
|
|
|
error status if there were any unexpected failures. "make check
|
|
|
|
|
|
stop-on-test-failure=y" may be used to keep the old behavior.

|
* The _BSD_SOURCE and _SVID_SOURCE feature test macros are no longer
|
|
|
|
|
|
supported; they now act the same as _DEFAULT_SOURCE (but generate a
|
|
|
|
|
|
warning). Except for cases where _BSD_SOURCE enabled BSD interfaces that
|
|
|
|
|
|
conflicted with POSIX (support for which was removed in 2.19), the
|
|
|
|
|
|
interfaces those macros enabled remain available when compiling with
|
|
|
|
|
|
_GNU_SOURCE defined, with _DEFAULT_SOURCE defined, or without any feature
|
|
|
|
|
|
test macros defined.

* Added support for TX lock elision of pthread mutexes on s390 and s390x.
|
|
|
|
|
|
This may improve lock scaling of existing programs on TX capable systems.
|
|
|
|
|
|
The lock elision code is only built with --enable-lock-elision=yes and
|
|
|
|
|
|
then requires a GCC version supporting the TX builtins. With lock elision
|
|
|
|
|
|
default mutexes are elided via __builtin_tbegin, if the cpu supports
|
|
|
|
|
|
transactions. By default lock elision is not enabled and the elision code
|
|
|
|
|
|
is not built.

* CVE-2014-4043 The posix_spawn_file_actions_addopen implementation did not
|
|
|
|
|
|
copy the path argument. This allowed programs to cause posix_spawn to
|
|
|
|
|
|
deference a dangling pointer, or use an unexpected pathname argument if
|
|
|
|
|
|
the string was modified after the posix_spawn_file_actions_addopen

invocation.

* All supported architectures now use the main glibc sysdeps directory
|

|
|
|
|
distributed separately before glibc 2.17).

|
* The NPTL implementation of POSIX pthreads is no longer an "add-on".
|
|
|
|
|
|
On configurations that support it (all Linux configurations), it's now
|
|
|
|
|
|
used regardless of the --enable-add-ons switch to configure. It is no
|
|
|
|
|
|
longer possible to build such configurations without pthreads support.

* Locale names, including those obtained from environment variables (LANG
|
|
|
|
|
|
and the LC_* variables), are more tightly checked for proper syntax.
|
|
|
|
|
|
setlocale will now fail (with EINVAL) for locale names that are overly
|
|
|
|
|
|
long, contain slashes without starting with a slash, or contain ".." path
|
|
|
|
|
|
components. (CVE-2014-0475) Previously, some valid locale names were
|
|
|
|
|
|
silently replaced with the "C" locale when running in AT_SECURE mode
|
|
|
|
|
|
(e.g., in a SUID program). This is no longer necessary because of the
|
|
|
|
|
|
additional checks.

* On x86-64, the dynamic linker's lazy-binding support is now compatible
|
|
|
|
|
|
with application code using Intel MPX instructions. (With all previous
|
|
|
|
|
|
versions, the MPX register state could be clobbered when making calls
|
|
|
|
|
|
into or out of a shared library.) Note that while the new dynamic
|
|
|
|
|
|
linker is compatible with all known x86 hardware whether or not it
|
|
|
|
|
|
supports Intel MPX, some x86 instruction-set emulators might fail to
|
|
|
|
|
|
handle the new instruction encodings. This is known to affect Valgrind
|
|
|
|
|
|
versions up through 3.9 (but will be fixed in the forthcoming 3.10
|
|
|
|
|
|
release), and might affect other tools that do instruction emulation.

* Support for loadable gconv transliteration modules has been removed.
|
|
|
|
|
|
The support for transliteration modules has been non-functional for
|
|
|
|
|
|
over a decade, and the removal is prompted by security defects. The
|
|
|
|
|
|
normal gconv conversion modules are still supported. Transliteration
|
|
|
|
|
|
with //TRANSLIT is still possible, and the //IGNORE specifier
|
2014-08-27 02:43:07 +08:00

* The public headers no longer use __unused nor __block. This change is to
|
|
|
|
|
|
support compiling programs that are derived from BSD sources and use
|
|
|
|
|
|
__unused internally, and to support compiling with Clang's -fblock
|
2013-11-26 22:01:52 +08:00

* CVE-2012-4412 The strcoll implementation caches indices and rules for
|
|
|
|
|
|
large collation sequences to optimize multiple passes. This cache
|
|
|
|
|
|
computation may overflow for large collation sequences and may cause a
|
|
|
|
|
|
stack or buffer overflow. This is now fixed to use a slower algorithm
|
|
|
|
|
|
which does not use a cache if there is an integer overflow.

|
|
|
2013-09-23 13:50:02 +08:00
|
|
|
|
* CVE-2012-4424 The strcoll implementation uses malloc to cache indices and
|
|
|
|
|
|
rules for large collation sequences to optimize multiple passes and falls
|
|
|
|
|
|
back to alloca if malloc fails, resulting in a possible stack overflow.
|
|
|
|
|
|
The implementation now falls back to an uncached collation sequence lookup
|
|

if malloc fails.

|
* CVE-2013-4788 The pointer guard used for pointer mangling was not
|
|
|
|
|
|
initialized for static applications resulting in the security feature
|
|
|
|
|
|
being disabled. The pointer guard is now correctly initialized to a
|
|

to be recompiled to take advantage of the fix (bug 15754).

* The localedef utility now supports --big-endian and --little-endian

2013-10-26 08:48:25 +08:00
|
|
|
|
* Binary locale files now only depend on the endianness of the system for
|
|
|
|
|
|
which they are generated and not on other properties of that system. As a
|
|
|
|
|
|
consequence, binary files generated with new localedef may be incompatible
|
|
|
|
|
|
with old versions of the GNU C Library, and binary files generated with
|
|
|
|
|
|
old localedef may be incompatible with this version of the GNU C Library,
|
|
|
|
|
|
in the following circumstances:
|
|
|
|
|
|
|
|
|
|
|
|
+ Locale files may be incompatible on m68k systems.
|
|
|
|

Add _DEFAULT_SOURCE feature test macro.
This patch adds a feature test macro _DEFAULT_SOURCE to enable the
default set of header declarations.
The intention is: if _DEFAULT_SOURCE is not used there is no change to
the set of __USE_* macros glibc defines; if it's used on its own, and
without compiler options such as -std=c99 that define __STRICT_ANSI__,
again, there is no change; if it's used together with the macros it
approximately (i.e., apart from __USE_POSIX_IMPLICITLY) implies
(-D_BSD_SOURCE -D_SVID_SOURCE -D_POSIX_C_SOURCE=200809L), again, there
is no change. Otherwise, it causes the relevant features to be
enabled, even if __STRICT_ANSI__, or another feature test macro, would
cause them to be disabled.
This macro deliberately bundles the POSIX.1-2008 (non-X/Open)
functionality with the BSD/SVID/"misc" functionality, rather than
defining a macro that gives just the latter, as many of the header
cleanups resulting from removing _BSD_SOURCE and _SVID_SOURCE support
are only possible when BSD/SVID/"misc" is always bundled with
POSIX.1-2008.
Tested x86_64.
* include/features.h: Update comment documenting feature test
macros. Mention _DEFAULT_SOURCE in comment.
[_GNU_SOURCE] (_DEFAULT_SOURCE): Undefine and redefine.
[_DEFAULT_SOURCE]: Undefine and redefine _DEFAULT_SOURCE,
_BSD_SOURCE and _SVID_SOURCE.
[!__STRICT_ANSI__ && !_ISOC99_SOURCE && !_POSIX_SOURCE &&
!_POSIX_C_SOURCE && !_XOPEN_SOURCE && !_BSD_SOURCE &&
!_SVID_SOURCE]: Likewise.
[_DEFAULT_SOURCE && !_POSIX_SOURCE && !_POSIX_C_SOURCE]
(__USE_POSIX_IMPLICITLY): Define.
[_DEFAULT_SOURCE && !_POSIX_SOURCE && !_POSIX_C_SOURCE]
(_POSIX_SOURCE): Undefine and redefine.
[_DEFAULT_SOURCE && !_POSIX_SOURCE && !_POSIX_C_SOURCE]
(_POSIX_C_SOURCE): Likewise.
* manual/creature.texi (_DEFAULT_SOURCE): Document.
(Feature Test Macros): Update documentation of default features.
2013-12-19 21:32:42 +08:00
|
|
|
|
* A new feature test macro _DEFAULT_SOURCE is available to enable the same
|
|
|
|
|
|
set of header declarations that are enabled by default, even when other
|
|
|
|
|
|
feature test macros or compiler options such as -std=c99 would otherwise
|
|
|
|
|
|
disable some of those declarations.
|
|
|
|
|
|
|
2013-12-18 02:05:42 +08:00
|
|
|
|
* The _BSD_SOURCE feature test macro no longer enables BSD interfaces that
|
2013-12-18 02:11:48 +08:00
|
|
|
|
conflict with POSIX. The libbsd-compat library (which was a dummy library
|
|
|
|
|
|
that did nothing) has also been removed.
|
2014-01-29 15:20:37 +08:00
|
|
|
|
|
|
|
|
|
|
* Preliminary documentation about Multi-Thread, Async-Signal and
|
|
|
|
|
|
Async-Cancel Safety has been added.
|
2014-04-08 22:30:07 +08:00
|
|
|
|
|
|
|
|
|
|
* Change of ABI data structures for s390 and s390x:
|
|
|
|
|
|
On s390 and s390x the size of struct ucontext and jmp_buf was increased to
|
|
|
|
|
|
allow for future hardware extensions. All library functions that accept or
|
|
|
|
|
|
return these structures were versioned in order to provide backwards
|
|
|
|
|
|
compatibility with existing code. However, not all cases can be handled
|
|
|
|
|
|
with interface versioning. If an application embeds either structure into
|
|
|
|
|
|
another structure and that structure is passed to another compilation unit
|
|
|
|
|
|
which expects the newer larger-sized object then any access to the new
|
|
|
|
|
|
fields will result in undefined behaviour. Similarly any access to fields
|
|
|
|
|
|
that were moved by the enlarging of the structures will cause undefined
|
|
|
|
|
|
behaviour. To fix the undefined behaviour all objects that are part of the
|
|
|
|
|
|
final in-memory image must agree on the size of structures, and this may
|
|
|
|
|
|
require recompilation.

* CVE-2013-2207 Incorrectly granting access to another user's pseudo-terminal
|
|
|
|
|
|
has been fixed by disabling the use of pt_chown (Bugzilla #15755).
|
|
|
|
|
|
Distributions can re-enable building and using pt_chown via the new configure
|
|
|
|
|
|
option `--enable-pt_chown'. Enabling the use of pt_chown carries with it
|
|
|
|
|
|
considerable security risks and should only be used if the distribution
|
|
|
|
|
|
understands and accepts the risks.

|
|
|
|
|
2013-02-19 12:28:05 +08:00
|
|
|
|
* Add support for calling C++11 thread_local object destructors on thread
|
|
|
|
|
|
and program exit. This needs compiler support for offloading C++11
|
|
|
|
|
|
destructor calls to glibc.
|
|
|
|
|
|
|
2013-03-01 23:13:40 +08:00
|
|
|
|
* Improved worst case performance of libm functions with double inputs and
|
|
|
|
|
|
output.
|
|
|
|
|
|
|
|
|
|
|
|
* Support for priority inherited mutexes in pthread condition variables on
|
|
|
|
|
|
non-x86 architectures.
|
|
|
|
|
|
|
2013-06-29 06:53:57 +08:00
|
|
|
|
* Port to Xilinx MicroBlaze contributed by David Holsgrove.
|
|

|
|
|
|
|
* Optimized string functions for AArch64. Implemented by Marcus Shawcroft.
|
|
|
|
|
|
|
|
|
|
|
|
* Optimized string functions for ARM. Implemented by Will Newton and
|
|
|
|
|
|
Richard Henderson.
|
|
|
|
|
|
|
|
|
|
|
|
* Optimized libm functions for SPARC. Implemented by David S. Miller.
|
|
|
|
|
|
|
|
|
|
|
|
* Support for building more of ARM glibc as Thumb-2 code. Implemented by
|
|
|
|
|
|
Richard Henderson.
|
|
|
|
|
|
|
|
|
|
|
|
* Support for building most of MIPS glibc as MIPS16 code. Implemented by
|
|
|
|
|
|
Chung-Lin Tang, Maciej W. Rozycki and Maxim Kuvyrkov.
|
|

2013-03-15 15:00:03 +08:00
|
|
|
|
* Added a benchmark framework to track performance of functions in glibc.
|
|
|
|
|
|
|
2013-04-02 19:51:02 +08:00
|
|
|
|
* New <math.h> macro named issignaling to check for a signaling NaN (sNaN).
|
|
|
|
|
|
It is based on draft TS 18661 and currently enabled as a GNU extension.
|

|
|
|
|
|
2013-06-14 01:42:00 +08:00
|
|
|
|
* On Linux, the clock function now uses the clock_gettime system call
|
|
|
|
|
|
for improved precision, rather than old times system call.
|
2013-06-15 14:54:15 +08:00
|
|
|
|
|
2013-09-19 04:15:12 +08:00
|
|
|
|
* Added support for version-3 tz format files. This is needed when using
|
|
|
|
|
|
the tz database release 2013e or later, and affects a few unusual cases --
|
|
|
|
|
|
currently only TZ='America/Godthab' for time stamps after 2037.
|
|
|
|
|
|
|
2013-06-15 14:54:15 +08:00
|
|
|
|
* Added new API functions pthread_getattr_default_np and
|
|
|
|
|
|
pthread_setattr_default_np to get and set the default pthread
|
|
|
|
|
|
attributes of a process.
|
2013-07-02 23:49:30 +08:00
|
|
|
|
|
|
|
|
|
|
* Added support for TSX lock elision for pthread mutexes on i386 and x86-64.
|
|
|
|
|
|
This may improve lock scaling of existing programs on TSX capable systems.
|
|
|
|
|
|
When the --enable-lock-elision=yes parameter is specified at configure
|
|
|
|
|
|
time lock elision will be enabled by default for all PTHREAD_MUTEX_DEFAULT
|
|
|
|
|
|
mutexes.
|
2013-07-25 23:49:13 +08:00
|
|
|
|
|
|
|
|
|
|
* Support added for AT_HWCAP2 (to coincide with Linux kernel 3.10
|
|
|
|
|
|
availability). Implemented by Ryan S. Arnold.
|
|
|
|
|
|
|
|
|
|
|
|
* Support added for POWER8 platform. Implemented by Ryan S. Arnold.

* The new function secure_getenv allows secure access to the environment,
|
|
|
|
|
|
returning NULL if running in a SUID/SGID process. This function replaces
|
|
|
|
|
|
the internal function __secure_getenv.
|
|
|
|
|
|
|
2012-07-26 18:03:35 +08:00
|
|
|
|
* SystemTap static probes have been added into the dynamic linker.
|
|
|
|
|
|
Implemented by Gary Benson.
|
|
|
|
|
|
|
2012-05-29 13:50:15 +08:00
|
|
|
|
* Optimizations of string functions strstr, strcasestr and memmem.
|
|
|
|
|
|
Implemented by Maxim Kuvyrkov.
|
|
|
|
|
|
|
2012-08-03 21:42:47 +08:00
|
|
|
|
* The minimum Linux kernel version that this version of the GNU C Library
|
2012-08-08 00:40:32 +08:00
|
|
|
|
can be used with is 2.6.16.
|

|
|
|
|
|
2012-08-23 00:04:42 +08:00
|
|
|
|
* Optimizations of string functions memchr, wcschr, wcscpy, and wcsrchr for
|
|
|
|
|
|
powerpc POWER7. Implemented by Will Schmidt.
|
|
|
|
|
|
|
2012-08-23 04:31:12 +08:00
|
|
|
|
* New configure option --disable-nscd builds the C library such that it
|
|
|
|
|
|
never attempts to contact the Name Service Caching Daemon (nscd).
|
2012-08-23 04:35:55 +08:00
|
|
|
|
New configure option --disable-build-nscd avoids building nscd itself;
|
|
|
|
|
|
this is the default if --disable-nscd is used.
|
2012-08-23 04:31:12 +08:00
|
|
|
|
|
2012-11-29 01:07:39 +08:00
|
|
|
|
* Improved support for cross-compilation, including cross-testing and
|
|
|
|
|
|
bootstrap builds without a previously built glibc.
|
|
|
|
|
|
|
2012-12-14 04:40:06 +08:00
|
|
|
|
* Several testsuite tests are now able to test multiple IFUNC variants of an
|
2012-12-14 04:42:06 +08:00
|
|
|
|
interface, rather than just testing the one that would be chooen by
|
2012-12-14 04:40:06 +08:00
|
|
|
|
default.
|
|
|
|
|
|
|
2012-11-29 01:07:39 +08:00
|
|
|
|
* New configure options --with-bugurl and --with-pkgversion, for
|
|
|
|
|
|
distributors to use to embed their bug-reporting and package version
|
|
|
|
|
|
information in --help and --version output.
|
|
|
|
|
|
|
2012-08-29 12:33:39 +08:00
|
|
|
|
* The ttyname and ttyname_r functions on Linux now fall back to searching for
|
|
|
|
|
|
the tty file descriptor in /dev/pts or /dev if /proc is not available. This
|
|
|
|
|
|
allows creation of chroots without the procfs mounted on /proc.
|
|
|
|
|
|
|
2012-10-10 18:06:03 +08:00
|
|
|
|
* The `crypt' function now fails if passed salt bytes that violate the
|
|
|
|
|
|
specification for those values. On Linux, the `crypt' function will
|
|
|
|
|
|
consult /proc/sys/crypto/fips_enabled to determine if "FIPS mode" is
|
|
|
|
|
|
enabled, and fail on encrypted strings using the MD5 or DES algorithm
|
|
|
|
|
|
when the mode is enabled.
|
|
|
|
|
|
|
2012-10-25 05:50:46 +08:00
|
|
|
|
* The `clock_*' suite of functions (declared in <time.h>) is now available
|
|
|
|
|
|
directly in the main C library. Previously it was necessary to link with
|
|
|
|
|
|
-lrt to use these functions. This change has the effect that a
|
|
|
|
|
|
single-threaded program that uses a function such as `clock_gettime' (and
|
|
|
|
|
|
is not linked with -lrt) will no longer implicitly load the pthreads
|
|
|
|
|
|
library at runtime and so will not suffer the overheads associated with
|
|
|
|
|
|
multi-thread support in other code such as the C++ runtime library.

|
|
|
|
|
2012-11-29 15:31:13 +08:00
|
|
|
|
* New locales: ayc_PE, doi_IN, ia_FR, mni_IN, nhn_MX, niu_NU, niu_NZ,
|
|
|
|
|
|
sat_IN, and szl_PL.

|
* Support for the x32 ABI on x86-64 added. The x32 target is selected by
|
|
|
|
|
|
configuring glibc with:
|
|
|
|
|
|
BUILD_CC='gcc' CC='gcc -mx32' CXX='g++ -mx32'

Implemented by H.J. Lu.
|
|
|
|
|
|
|
2011-12-24 12:49:48 +08:00
|
|
|
|
* ISO C11 support:
|
|
|
|
|
|
|
|
|
|
|
|
+ define static_assert
|
|
|
|
|
|
|
|
|
|
|
|
+ do not declare gets
|
|
|
|
|
|
|
|
|
|
|
|
+ declare at_quick_exit and quick_exit also for ISO C11
|
|
|
|
|
|
|
|
|
|
|
|
+ aligned_alloc. NB: The code is deliberately allows the size parameter
|
|
|
|
|
|
to not be a multiple of the alignment. This is a moronic requirement
|
|
|
|
|
|
in the standard but it is only a requirement on the caller, not the
|
|
|
|
|
|
implementation.

|
2011-12-24 13:40:15 +08:00
|
|
|

+ timespec_get added
|
2012-01-08 00:04:33 +08:00
|
|
|
|
|
|
|
|
|
|
+ uchar.h support added

|
|
|
2012-01-08 23:07:26 +08:00

Implemented by Ulrich Drepper.
|
|
|
|
|
|
|
2012-05-14 13:02:03 +08:00
|
|
|
|
* Support for the IA-64 has been moved to ports.
|
2012-01-08 09:33:23 +08:00
|
|
|
|
|
|
|
|
|
|
* Remove support for anything but ELF binary format
|
2012-01-09 00:55:32 +08:00
|
|
|
|
|
|
|
|
|
|
* Checking versions of poll, ppoll added.
|
|
|
|
|
|
Implemented by Ulrich Drepper.
|
2012-01-11 11:26:22 +08:00
|
|
|
|
|
|
|
|
|
|
* More generic and 64-bit performance optimizations to math functions.
|
|
|
|
|
|
Implemented by Ulrich Drepper.
|
2012-05-11 02:16:53 +08:00
|
|
|
|
|
|
|
|
|
|
* New configure option --enable-obsolete-rpc makes the deprecated RPC
|
|
|
|
|
|
headers and functions available at compile time as they were before
|
|
|
|
|
|
version 2.14. This option will be removed at some time in the future
|
|
|
|
|
|
after the TI-RPC library becomes fully sufficient for the needs of
|
|
|
|
|
|
existing applications.

|
|
|
|
|
2012-05-26 03:19:30 +08:00
|
|
|
|
* Compatibility code for Linux kernel versions before 2.4 has been removed.
|
2012-05-14 22:11:02 +08:00
|
|
|
|
Note that glibc is not expected to work with any Linux kernel version
|
|
|
|
|
|
before 2.6.
|
2012-05-23 00:52:55 +08:00
|
|
|
|
|
2012-05-24 22:45:49 +08:00
|
|
|
|
* New header <sys/auxv.h> and function getauxval allowing easy access to
|
|
|
|
|
|
the AT_* key-value pairs passed from the Linux kernel. The header also
|
|
|
|
|
|
defines the HWCAP_* bits associated with the AT_HWCAP key.
|
|
|
|
|
|
|
2012-05-23 00:52:55 +08:00
|
|
|
|
* New locales: mag_IN
|
2012-05-26 04:49:31 +08:00
|
|
|
|
|
|
|
|
|
|
* New configure option --enable-systemtap builds SystemTap static probes
|
|
|
|
|
|
into libc for setjmp and longjmp and into libpthread for various operations.
|
|
|
|
|
|
So far the setjmp/longjmp probes and some of the libpthread probes are
|
|
|
|
|
|
provided only for i*86 and x86_64.
|
|
|
|
|
|
Implemented by Roland McGrath and Rayson Ho.

|
|
|
|
|
|
|
2012-06-05 02:46:37 +08:00
|
|
|
|
* More optimized functions for PowerPC. Implemented by Adhemerval Zanella
|
|
|
|
|
|
and Will Schmidt.
|
2012-05-28 02:37:42 +08:00
|
|
|
|
|
|
|
|
|
|
* More optimized functions for SPARC. Implemented by David S. Miller.
|
|
|
|
|
|
|
|
|
|
|
|
* Improved support for cross-compilation, especially bootstrap builds
|
|
|
|
|
|
without a previously built glibc.
|
|
|
|
|
|
|
|
|
|
|
|
* Ports for the TILE-Gx and TILEPro families of processors. Contributed by
|
|
|
|
|
|
Chris Metcalf from Tilera.
|
|
|
|
|
|
|
|
|
|
|
|
* Support for the old ARM ABI has been removed from ports. Only the EABI is
|
|
|
|
|
|
now supported for ARM processors.
|
|
|
|
|
|
|
|
|
|
|
|
* The hard-float variant of the ARM EABI now uses /lib/ld-linux-armhf.so.3
|
|
|
|
|
|
as the name of the dynamic linker, to distinguish it from the
|
|
|
|
|
|
/lib/ld-linux.so.3 dynamic linker used for the base EABI.
|
|
|
|
|
|
|
|
|
|
|
|
* Support for CRIS has been removed from ports.
|
2012-06-05 02:46:37 +08:00
|
|
|
|
|
|
|
|
|
|
* A new class of installed header has been documented for low-level
|
|
|
|
|
|
platform-specific functionality. PowerPC added the first instance with a
|
|
|
|
|
|
function to provide time base register access. Contributed by Tulio
|
|

|
|
|
Magno Quites Machado Filho.

2012-06-16 03:13:21 +08:00
|
|
|
|
|
|
|
|
|
|
* ix86 configurations now install header files that are consistent with
|
|
|
|
|
|
what x86-64 configurations install. These same header files can be used
|
|
|
|
|
|
for -m32, -m64, or -mx32 builds.

|
|
* Math library bug fixes. A thorough audit of all open math library bugs was
|
|
|
|
|
|
conducted by Joseph Myers. Significant progress was made on many math
|
|
|
|
|
|
library bugs resulting in more accurate exceptions and function results.

|
|
|
|
|
|
|
* Timezone data is no longer installed. Timezone-related binaries and scripts
|
|
|
|
|
|
will continue to be installed. Users should obtain their timezone data from
|
|
|
|
|
|
their distribution provider or from the tzdata package at

* The RPC implementation in libc is obsoleted. Old programs keep working
|
|
|
|
|
|
but new programs cannot be linked with the routines in libc anymore.
|
|
|
|
|
|
Programs in need of RPC functionality must be linked against TI-RPC.
|
2011-05-31 00:31:25 +08:00
|
|
|
|
The TI-RPC implementation is IPv6 enabled and there are other benefits.
|
2011-05-05 19:39:34 +08:00
|
|
|
|
|
|
|
|
|

Visible changes of this change include (obviously) the inability to link
|
2011-05-06 19:47:33 +08:00
|
|
|
|
programs using RPC functions without referencing the TI-RPC library and the
|
|
|
|
|
|
removal of the RPC headers from the glibc headers.

* The malloc hook implementation is marked deprecated and will be removed
|
|
|
|
|
|
from the default implementation in the next version. The design never
|
|
|
|
|
|
worked ever since the introduction of threads. Even programs which do
|
|
|
|
|
|
not create threads themselves can use multiple threads created internally.

Instead it is used to synthesize the shadow.byname table, should it be

the second request. The 'single-request-reopen' option in /etc/resolv.conf
|
|
|
|
|
|
can be used to select this mode right away, instead of rediscovering the
|
|
|
|
|
|
necessity is every process again.

* It is now possible to install audit libraries for the dynamic linker using
|
|
|
|
|
|
LD_AUDIT. Implemented by Ulrich Drepper.
|
2005-07-03 12:43:32 +08:00
|

|
|
|
|
|
|
|
* The LinuxThreads add-on, providing pthreads on Linux 2.4 kernels, is no
|
|
|
|
|
|
longer supported. The new NPTL implementation requires Linux 2.6 kernels.
|
|
|
|
|
|
For a libc and libpthread that works well on Linux 2.4 kernels, we
|
|
|
|
|
|
recommend using the stable 2.3 branch.

* The new function open_wmemstream acts like open_memstream,
|
|
|
|
|
|
but uses a wchar_t wide character buffer.
|
|
|
|
|
|
|
|
|
|
|
|
* The new function ppoll is an improved version of poll, similar to pselect.
|
|
|
|
|
|
|
|
|
|
|
|
* New interfaces: fdopendir, openat, fstatat, fchmodat, fchownat,
|
|
|
|
|
|
futimesat, faccessat, mkdirat, mkfifoat, mknodat,
|

renameat, unlinkat, linkat, symlinkat, readlinkat.
|
|
|
|

|
|
|
|
|
|
for compatibility with some other systems.
|
|
|
|
|
|
|
|
|
|

Version 2.3.4
|
|
|
|
|
|
|
|
|
|
|
|
* Support for RFC 3678. Real implementations exist only for Linux so far.
|
|
|
|
|
|
Implemented by Ulrich Drepper.
|
2004-09-17 16:44:34 +08:00
|
|
|
|
|
|
|
|
|
|
* nscd can now cache entries persistently. Expiring entries are reloaded.
|
|
|
|
|
|
For speedups the cache can be shared in memory with client processes.
|
|
|
|
|
|
Implemented by Ulrich Drepper.
|
|
|
|
|
|
|
|
|
|
|
|
* nscd can now perform SELinux checks.
|
|
|
|
|
|
Implemented by Matthew Rickard <mjricka@epoch.ncsc.mil>.
|
|
|
|
|
|
|
2004-10-20 00:05:21 +08:00
|
|
|
|
* getaddrinfo queries are now cached. Canonical name lookup is performed
|
2004-09-17 16:44:34 +08:00
|
|
|
|
efficiently.
|
|
|
|
|
|
Implemented by Ulrich Drepper.
|
|
|
|
|
|
|
|
|
|
|
|
* The nothrow function attribute is used when headers are used by gcc when
|
|
|
|
|
|
compiling C code. This can avoid significant amounts of exception
|
|
|
|
|
|
handling data.
|
|
|
|
|
|
|
|
|
|
|
|
* The malloc functions perform more error checking and are stricter when
|
|
|
|
|
|
it comes to reacting on errors. The default action is to terminate
|
2004-10-20 00:05:21 +08:00
|
|
|
|
the process after showing an error message. Implemented by Ulrich Drepper.
|
2004-09-17 16:44:34 +08:00
|
|
|
|
|
|
|
|
|
|
* Reverse lookups of IPv6 addresses does not use bit string or .ip6.int
|
2004-10-20 00:05:21 +08:00
|
|
|
|
lookups anymore unless explicitly requested. Implemented by Ulrich Drepper.
|
|
|
|
|
|
|
|
|
|
|
|
* Namespaces in ld.so are implemented. DSOs can be loaded in separate
|
|
|
|
|
|
namespaces using the new function dlmopen(). This feature is of course,
|
|
|
|
|
|
like most other dynamic loading functionality, not available in statically
|
|
|
|
|
|
linked applications. Implemented by Ulrich Drepper.
|
|
|
|
|
|
|
|
|
|
|
|
* Low-overhead boundary checking variants of string and some stdio functions
|
|
|
|
|
|
were added. These are to be used in conjunction with a gcc patch by
|
|
|
|
|
|
Jakub Jelinek which adds calls to these functions if possible.
|
2004-12-19 17:41:58 +08:00
|
|
|
|
Implemented by Jakub Jelinek and Ulrich Drepper.

* Old code for several operating systems and machine architectures that
|
|
|
|
|
|
have not been in working condition in a long time have been removed from
|
|
|
|
|
|
the main source tree maintained by the GNU C Library's maintainers.
|
|
|
|
|
|
These files are now reside in the separate `ports' source module
|
|
|
|
|
|
that is usable as an add-on when building the library.

Version 2.3.2

|
|
|
|
|
2002-12-03 08:54:55 +08:00
|
|
|
|
* Thread-safe interfaces for many functions that access locale data
|
|
|
|
|
|
were added in version 2.3, but these features were omitted from NEWS.
|
|
|
|
|
|
Many functions have variants with an `_l' suffix that take a `locale_t'
|
|
|
|
|
|
object as a parameter rather than consulting the current locale.
|
|
|
|
|
|
The new functions `newlocale', `duplocale', and `freelocale' in <locale.h>
|
|
|
|
|
|
create and maintain `locale_t' objects. Additionally, the new function
|
|
|
|
|
|
`uselocale' sets "the current locale" (as used by functions not so
|
|
|
|
|
|
parameterized) set for an individual thread. These features were added
|
|
|
|
|
|
in version 2.3, implemented by Ulrich Drepper and Roland McGrath.

|
|
|
* The functions getresuid, getresgid, setresuid, and setresgid, which
|
|
|
|
|
|
have long been available on Linux, are now declared in <unistd.h>
|
|
|
|
|
|
and are now also available on the Hurd.
|
|
|
|
|
|
|
|
|
|
|
|
* ELF thread-local storage support (TLS) now works on x86-64.
|
2002-10-14 16:03:18 +08:00
|
|
|
|
|
|
|
|
|
|
* The new dynamic string token $LIB is expanded in shared library names.
|
|
|
|
|
|
This normally expands to lib, but on some 64-bit platforms to lib64 instead.

* Aldy Hernandez contributed complete software floating point support for
|
|
|
|
|
|
PowerPC machines with no FPU.
|
|
|
|
|
|
|
2002-11-05 16:43:05 +08:00

* The `btowc' function should work at least twice as fast due to
|
|
|
|
|
|
specialized callbacks in the iconv modules. Implemented by Bruno Haible.
|
2003-01-13 17:28:02 +08:00

|
|
|
2023-05-20 21:37:47 +08:00
|
|
|
|
* With appropriate thread add-ons cancelable functions are now implemented
|
2003-01-13 17:28:02 +08:00
|
|
|
|
in libc.so as well. No need to call the function in libpthread. This
|
|
|
|
|
|
change allowed to finally disable the incorrect and expensive handling
|
|
|
|
|
|
of weak definition in ld.so.
|
|
|
|
|
|
|
|
|
|
|
|
* Yet more PLT entries in libc.so have been removed. We finally arrived
|
|
|
|
|
|
at the bare minimum. Startup times improved appropriately.
|
|
|
|
|
|
|
|
|
|
|
|
* Support for the new Linux/x86 system call interface was added. The
|
|
|
|
|
|
AT_SYSINFO auxiliary vector entry is recognized and handled.

|
|
|
|
|
|
charsets.
|
|
|
|
|
|
|
|
|
|

Version 2.2.6
|
|
|
|
|
|
|
|
|
|
|
|
* The Hurd now uses the GNU libio implementation of stdio rather than the
|
|
|
|
|
|
old GNU stdio implementation, and uses a new ABI (libc.so.0.3).
|
|
|
|
|
|
|
|
|
|
|
|
* The Hurd on x86 now has the `ioperm' function and <sys/io.h> header file
|
|
|
|
|
|
with the same behavior as the Linux system call of the same name.

|
|
|
severe performance problems. Patch by David Mosberger.
|
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
2001-03-04 16:47:11 +08:00
|
|

* Intel's IA-64 math library is largely integrated. It provides fast and
|
2001-03-04 02:21:04 +08:00
|
|
|
|
accurate implementatations for most basic and standard math functions
|

|
|
|
|
|
|
2001-04-05 15:21:12 +08:00

* Lots of headers were cleaned up. Using the tool in the conform/ subdir
|
2001-01-31 15:42:03 +08:00
|
|
|
|
we can now check for namespace violations and missing declarations. The
|
|
|
|
|
|
result is that almost all headers are now Unix-compliant (as defined in
|
|
|
|
|
|
the upcoming XPG6). The negative side is that some programs might need
|
|
|
|
|
|
corrections, too, if they depend on the incorrect form of the headers in
|
|
|
|
|
|
previous versions which defined too many symbols and included too many
|
|
|
|
|
|
other headers.

provided and the conversion happens based on this data.

|
|
* The gencat program now parses the input file according to the charset
|
|
|
|
|
|
selected by the LC_CTYPE category. This is important for stateful
|
|
|
|
|
|
character sets. To make generating catalogs easier there is a way
|
|
|
|
|
|
to overwrite the charset selected by the locale: before the first
|
|
|
|
|
|
message or $ quote line the catalog can contain a line like
|
|
|
|
|
|
|
|
|
|
|
|
$ codeset=ISO-8859-2
|
|
|
|
|
|
|
|
|
|
|
|
to select the charset (ISO-8859-2 in this case).

This change could in some situations effect backward compatibility. Since
|
|
|
|
|
|
now `_res' is a thread-local instead of a global variable, modifying it
|
|
|
|
|
|
in one thread does not have any effect in other threads.

|
|
|

2000-01-01 03:29:52 +08:00
|
|

|
|
|
|
|
|
(conforming to either C89 or C99 standard).

|
|
* Richard Henderson corrected size of struct timeval on Linux/Alpha to
|
|
|
|
|
|
conform to POSIX member type requirements. Symbol versions have been
|
|
|
|
|
|
adjusted as needed within the library, and for direct use by applications,
|
|
|
|
|
|
but there is potential for problems if third-party libraries use
|
|
|
|
|
|
struct timeval as part of their interface. This does not present
|
|
|
|
|
|
a problem for X and other "essential" system libraries.

|
|
|
|
1997-02-15 12:31:36 +08:00
|

|
1997-02-19 12:43:53 +08:00
|
|
|
|
model and probably more was implemented by Ulrich Drepper.

|
|
1997-02-19 12:43:53 +08:00

1997-02-15 12:31:36 +08:00
|
|
|
|
symbol level.

|
|
|

|
Version 2.0.1
|
|
|
|
|
|
|
|
|
|
|
|
* fixed lots of header problems (especially Linux/GNU specific)
|
|
|
|
|
|
|
|
|
|
|
|
* dynamic loader preserves all registers
|
|
|
|
|
|
|
|
|
|
|
|
* Roland McGrath provided support for handling of auxiliary objects in
|
|
|
|
|
|
the ELF dynamic loader.
|
|
|
|
|
|
|
|
|
|
|
|
* support for parallel builds is improved
|
|
|
|
|
|

1996-06-23 05:14:17 +08:00
|
|
|
|
Version 2.0
|
1995-02-18 09:27:10 +08:00
|
|
|
|
|
1996-03-20 05:59:41 +08:00
|
|
|
|
* GNU extensions are no longer declared by default. To enable them you
|
|
|
|
|
|
must define the macro `_GNU_SOURCE' in your program or compile with
|
|
|
|
|
|
`-D_GNU_SOURCE'.
|
|
|
|
|
|
|
1995-02-18 09:27:10 +08:00
|
|
|
|
* The library has changed from using GNU ld symbol aliases to using weak
|
|
|
|
|
|
symbols where available. The ELF object file format supports weak
|
|
|
|
|
|
symbols; GNU ld also supports weak symbols in the a.out format. (There
|
|
|
|
|
|
is also now support for other GNU ld extensions in ELF. Use the
|
1995-02-21 14:17:59 +08:00
|
|
|
|
`--with-elf' option to configure to indicate you have ELF, and
|
|
|
|
|
|
`--with-gnu-ld' if using GNU ld.) This change resulted in the deletion
|
1995-02-18 09:27:10 +08:00
|
|
|
|
of many files which contained only symbol aliases, reducing the size of
|
|
|
|
|
|
the source and the compiled library; many other files were renamed to
|
|
|
|
|
|
less cryptic names previously occupied by the symbol alias files.
|
1996-08-26 18:28:45 +08:00
|
|
|
|
There is a new header file <elf.h> for programs which operate on
|
|
|
|
|
|
files in the ELF format.
|
1995-03-21 15:58:50 +08:00
|
|
|
|
|
|
|
|
|
|
* Converted to Autoconf version 2, so `configure' has more options.
|
|
|
|
|
|
Run `configure --help' to see the details.
|
|
|
|
|
|
|
|
|
|
|
|
* The library can now be configured to build profiling, highly-optimized
|
1995-08-08 05:45:04 +08:00
|
|
|
|
(but undebuggable), and/or shared libraries (ELF with GNU ld only). The
|
|
|
|
|
|
`--enable-profile', `--enable-omitfp', and `--enable-shared' options to
|
|
|
|
|
|
`configure' enable building these extra libraries. The shared library is
|
|
|
|
|
|
built by default when using both ELF and GNU ld. When shared libraries
|
|
|
|
|
|
are enabled, the new library `-ldl' is available for arbitrary run-time
|
|
|
|
|
|
loading of shared objects; its interface is defined in <dlfcn.h>. The
|
|
|
|
|
|
new header file <link.h> gives access to the internals of the run-time
|
1997-01-26 13:33:35 +08:00
|
|
|
|
dynamic linker, `ld.so'. The shell script `ldd' is similar to the
|
|
|
|
|
|
application of same name on other systems and it provides information
|
|
|
|
|
|
about dynamically linked binaries.
|
1995-03-21 15:58:50 +08:00
|
|
|
|
|
1996-01-02 16:57:42 +08:00
|
|
|
|
* The C library now provides the run-time support code for profiling
|
|
|
|
|
|
executables compiled with `-pg'. Programs can control the profiling code
|
1996-03-20 05:59:41 +08:00
|
|
|
|
through the interface in <sys/gmon.h>. The `gmon.out' files written by
|
|
|
|
|
|
the GNU C library can be read only by GNU `gprof' (from GNU binutils);
|
|
|
|
|
|
the support for this file format was contributed by David Mosberger-Tang.
|
1996-01-02 16:57:42 +08:00
|
|
|
|
|
1996-03-06 05:41:30 +08:00
|
|
|
|
* The math code has been replaced with a math library based on fdlibm from
|
1997-01-26 13:33:35 +08:00
|
|
|
|
Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by
|
|
|
|
|
|
Ian Taylor with `float' functions and by Ulrich Drepper with `long double'
|
|
|
|
|
|
functions. The math functions now reside in a separate library, so
|
|
|
|
|
|
programs using them will need to use `-lm' their linking commands.
|
|
|
|
|
|
|
|
|
|
|
|
* John C. Bowman contributed optimized ix87 assembler inline functions.

1996-06-25 16:56:57 +08:00
|
|
|
|
* Ulrich Drepper has contributed support for an `/etc/nsswitch.conf'
|
|
|
|
|
|
mechanism similar to that found in Solaris 2. This is now used for the
|
1997-01-26 13:33:35 +08:00
|
|
|
|
group, passwd, hosts, networks, services, protocols, rpc, ethers,
|
|
|
|
|
|
shadow, netgroup, publickey, and alias databases. The `nsswitch.conf'
|
|
|
|
|
|
file controls what services are used for each individual database. This
|
|
|
|
|
|
works by loading shared libraries with names specified in `nsswitch.conf',
|
|
|
|
|
|
so service modules can be changed or added at any time without even
|
|
|
|
|
|
relinking any program. Currently there are the file, db, and NIS based
|
|
|
|
|
|
NSS services available.

Mon Jun 24 22:39:12 1996 Richard Henderson <rth@tamu.edu>
* sysdeps/alpha/dl-machine.h (ELF_MACHINE_RUNTIME_TRAMPOLINE):
A .plt entry now loads the .rela.plt offset directly rather
than making us calculate it.
Sun Jun 23 15:24:05 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* time/Makefile ($(installed-localtime-file) rule): Do
$(make-target-directory) first.

Sat Jun 22 16:49:47 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* rpm/Makefile ($(config)): Make sure the word list in the for
loop is syntactically non-empty.
1996-06-25 16:56:57 +08:00
|
|
|
|
|
1995-03-21 15:58:50 +08:00
|
|
|
|
* The new functions `strtoq' and `strtouq' parse integer values from
|
|
|
|
|
|
strings, like `strtol' and `strtoul', but they return `long long int' and
|
|
|
|
|
|
`unsigned long long int' values, respectively (64-bit quantities).
|
|
|
|
|
|
|
|
|
|
|
|
* The new functions `strtof' and `strtold' parse floating-point values from
|
|
|
|
|
|
strings, like `strtod', but they return `float' and `long double' values,
|
|
|
|
|
|
respectively (on some machines `double' and `long double' are the same).
|
|
|
|
|
|
|
|
|
|
|
|
* Ulrich Drepper has contributed new implementations of the floating-point
|
|
|
|
|
|
printing and reading code used in the `printf' family of functions and
|
|
|
|
|
|
`strtod', `strtof', and `strtold'. These new functions are perfectly
|
|
|
|
|
|
accurate, and much faster than the old ones.
|
|
|
|
|
|
|
1997-01-26 13:33:35 +08:00
|
|
|
|
* The implementation of the POSIX locale model was completely rewritten by
|
|
|
|
|
|
Ulrich Drepper. This includes the new programs `localedef' and `locale'
|
|
|
|
|
|
to compile the POSIX locale definition.
|
|
|
|
|
|
|
|
|
|
|
|
* The former dummy implementations of the strcoll and strxfrm function are
|
|
|
|
|
|
now replaced by fully functional code contributed by Ulrich Drepper. The
|
|
|
|
|
|
collation information comes from the POSIX locale definitions.
|
|
|
|
|
|
|
1995-03-21 15:58:50 +08:00
|
|
|
|
* The new header <langinfo.h> defines an interface for accessing
|
|
|
|
|
|
various locale-dependent data (using the locale chosen with `setlocale').
|
|
|
|
|
|
|
1996-03-06 05:41:30 +08:00
|
|
|
|
* Ulrich Drepper has contributed a new suite of functions for operation on
|
1997-01-26 13:33:35 +08:00
|
|
|
|
wide-character and multibyte-character strings, in <wchar.h>;
|
1996-03-29 09:04:20 +08:00
|
|
|
|
and classification and case conversion of wide characters, in <wctype.h>.
|
2023-05-20 21:37:47 +08:00
|
|
|
|
These new functions are conforming to the ISO C, Amendment 1 specification.
|
1997-01-26 13:33:35 +08:00
|
|
|
|
|
|
|
|
|
|
* There is now a second implementation of the standard I/O library available.
|
|
|
|
|
|
It comes from GNU libg++ as was written by Per Bothner, heavily modified
|
|
|
|
|
|
by Hongjiu Lu and made thread safe by Ulrich Drepper.
|
1996-03-06 05:41:30 +08:00
|
|
|
|
|
1996-01-02 16:57:42 +08:00
|
|
|
|
* You can now use positional parameter specifications in format strings
|
1995-03-21 15:58:50 +08:00
|
|
|
|
for the `printf' and `scanf' families of functions. For example,
|
|
|
|
|
|
`printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints
|
|
|
|
|
|
``Number 6, Mr Jones''. This is mainly useful when providing different
|
1995-03-24 15:59:23 +08:00
|
|
|
|
format strings for different languages, whose grammars may dictate
|
|
|
|
|
|
different orderings of the values being printed. To support this
|
1995-03-21 15:58:50 +08:00
|
|
|
|
feature, the interface for `register_printf_handler' has changed; see
|
1995-03-24 15:59:23 +08:00
|
|
|
|
the header file <printf.h> for details.
|
1995-03-21 15:58:50 +08:00
|
|
|
|
|
|
|
|
|
|
* The `printf' and `scanf' families of functions now understand a new
|
|
|
|
|
|
formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says
|
|
|
|
|
|
to group numbers as indicated by the locale; for `scanf' and friends, this
|
|
|
|
|
|
says to accept as valid only a number with all the proper grouping
|
|
|
|
|
|
separators in the right places. In the default "C" locale, numbers are
|
|
|
|
|
|
not grouped; but locales for specific countries will define the usual
|
|
|
|
|
|
conventions (i.e. separate thousands with `,' in the US locale).
|
1995-02-18 09:27:10 +08:00
|
|
|
|
|
|
|
|
|
|
* The pgrp functions have been regularized, slightly incompatibly but much
|
|
|
|
|
|
less confusingly. The core functions are now `getpgid' and `setpgid',
|
|
|
|
|
|
which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no
|
|
|
|
|
|
argument) and BSD `setpgrp' (identical to `setpgid') functions are
|
|
|
|
|
|
provided for compatibility. There is no longer an incompatible `getpgrp'
|
|
|
|
|
|
with an argument declared under _BSD_SOURCE; no BSD code uses it.
|
|
|
|
|
|
|
|
|
|
|
|
* The new header file <fts.h> and suite of functions simplify programs that
|
|
|
|
|
|
operate on directory trees. This code comes from 4.4 BSD.
|
|
|
|
|
|
|
1997-01-26 13:33:35 +08:00
|
|
|
|
* The resolver code has been updated from the BIND 4.9.5-P1 release.
|
|
|
|
|
|
Parts of the code were heavily modified by Ulrich Drepper to fit in the
|
|
|
|
|
|
NSS scheme used in glibc.
|
1995-02-18 09:27:10 +08:00
|
|
|
|
|
|
|
|
|
|
* There is a new malloc debugging hook `__memalign_hook'.
|
|
|
|
|
|
|
|
|
|
|
|
* There are new typedefs `ushort' for `unsigned short int' and `uint' for
|
|
|
|
|
|
`unsigned int' in <sys/types.h>. These are for compatibility only and
|
|
|
|
|
|
their use is discouraged.
|
|
|
|
|
|
|
|
|
|
|
|
* The `-lmcheck' library to enable standard malloc debugging hooks is now
|
|
|
|
|
|
done differently, so that it works even without GNU ld.
|
1995-02-21 14:17:59 +08:00
|
|
|
|
|
1995-02-25 09:23:32 +08:00
|
|
|
|
* New function `euidaccess' checks allowed access to a file like `access',
|
|
|
|
|
|
but using the effective IDs instead of the real IDs.
|
1995-03-21 15:58:50 +08:00
|
|
|
|
|
|
|
|
|
|
* The time zone data files have been updated for the latest and greatest
|
|
|
|
|
|
local time conventions of the countries of the world.
|
|
|
|
|
|
|
|
|
|
|
|
* The new function `dirfd' extracts the file descriptor used by a DIR stream;
|
|
|
|
|
|
see <dirent.h>.
|
|
|
|
|
|
|
|
|
|
|
|
* The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface
|
|
|
|
|
|
for formatting floating-point numbers. They are provided only for
|
1997-01-26 13:33:35 +08:00
|
|
|
|
compatibility; new programs should use `sprintf' instead. There are
|
|
|
|
|
|
also equivalent function for the `long double' floating-point type and
|
|
|
|
|
|
all functions also exist in a reentrant form.
|
1995-03-27 18:24:00 +08:00
|
|
|
|
|
|
|
|
|
|
* The new auxiliary library `-lutil' from 4.4 BSD contains various
|
|
|
|
|
|
functions for maintaining the login-record files (primarily of use to
|
|
|
|
|
|
system programs such as `login'), and convenient functions for
|
|
|
|
|
|
allocating and initializing a pseudo-terminal (pty) device.
|
1995-09-27 10:50:10 +08:00
|
|
|
|
|
|
|
|
|
|
* Ulrich Drepper has contributed new support for System V style
|
|
|
|
|
|
shared memory and IPC on systems that support it.
|
|
|
|
|
|
|
|
|
|
|
|
* Ulrich Drepper has contributed several miscellaneous new functions found
|
|
|
|
|
|
in System V: The `hsearch' family of functions provide an effective
|
|
|
|
|
|
implementation of hash tables; `a64l' and `l64a' provide a very simple
|
|
|
|
|
|
binary to ASCII mapping; `drand48' and friends provide a 48-bit random
|
|
|
|
|
|
number generator.
|
|
|
|
|
|
|
|
|
|
|
|
* Ulrich Drepper has contributed new reentrant counterparts for the
|
|
|
|
|
|
`random' and `hsearch' families of functions; `random_r', `hsearch_r', etc.
|
|
|
|
|
|
|
|
|
|
|
|
* Ulrich Drepper has contributed new, highly-optimized versions of several
|
|
|
|
|
|
string functions for the i486/Pentium family of processors.
|
|
|
|
|
|
|
1996-01-02 16:57:42 +08:00
|
|
|
|
* Ulrich Drepper has updated the Linux-specific code, based largely
|
1995-09-27 10:50:10 +08:00
|
|
|
|
on work done in Hongjiu Lu's version of GNU libc for Linux.
|
1997-01-26 13:33:35 +08:00
|
|
|
|
The GNU library now supports Linux versions 2.0.10 and later,
|
|
|
|
|
|
using the ELF object file format (i[3456]86-*-linux).
|
1995-09-27 10:50:10 +08:00
|
|
|
|
|
1996-03-20 05:59:41 +08:00
|
|
|
|
* Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux).
|
|
|
|
|
|
|
1997-01-26 13:33:35 +08:00
|
|
|
|
* David Mosberger-Tang and Richard Henderson have ported the C library
|
|
|
|
|
|
to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the
|
|
|
|
|
|
dynamic linking support for ELF/Alpha.
|
|
|
|
|
|
|
|
|
|
|
|
* Richard Henderson contributed several Alpha optimized assembler function
|
|
|
|
|
|
for arithmetic and string handling.
|
1996-03-20 05:59:41 +08:00
|
|
|
|
|
1995-09-27 10:50:10 +08:00
|
|
|
|
* Ulrich Drepper has contributed a new set of message catalog functions to
|
1996-06-23 05:14:17 +08:00
|
|
|
|
support multiple languages using the <libintl.h> interface, for use with
|
|
|
|
|
|
his new package GNU gettext. Translation volunteers have contributed
|
|
|
|
|
|
catalogs of the library's messages in Spanish, German, and Korean.
|
|
|
|
|
|
|
|
|
|
|
|
* For compatibility with XPG4, Ulrich Drepper has contributed the `gencat'
|
|
|
|
|
|
program and the `catgets' function for reading the catalog files it
|
|
|
|
|
|
creates. (The <libintl.h> interface is preferred; we include the
|
|
|
|
|
|
<nl_types.h> interface using `catgets' only for source compatibility with
|
|
|
|
|
|
programs already written to use it.)
|
1996-01-02 16:57:42 +08:00
|
|
|
|
|
|
|
|
|
|
* New header file <values.h> gives SVID-compatible names for <limits.h>
|
|
|
|
|
|
constants.
|
|
|
|
|
|
|
|
|
|
|
|
* Various new macros, declarations, and small header files for compatibility
|
|
|
|
|
|
with 4.4 BSD.
|
|
|
|
|
|
|
|
|
|
|
|
* New function `group_member' is a convenient way to check if a process has
|
|
|
|
|
|
a given effective group ID.
|
|
|
|
|
|
|
|
|
|
|
|
* When using GCC 2.7 and later, the socket functions are now declared in a
|
|
|
|
|
|
special way so that passing an argument of type `struct sockaddr_in *',
|
|
|
|
|
|
`struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic
|
|
|
|
|
|
`struct sockaddr *' type, does not generate a type-clash warning.
|
|
|
|
|
|
|
|
|
|
|
|
* New function `error' declared in header file <error.h> is a convenient
|
1996-12-20 09:39:50 +08:00
|
|
|
|
function for printing error messages and optionally exiting; this is the
|
1996-01-02 16:57:42 +08:00
|
|
|
|
canonical function used in GNU programs. The new functions `err', `warn',
|
|
|
|
|
|
and friends in header file <err.h> are the canonical 4.4 BSD interface for
|
|
|
|
|
|
doing the same thing.
|
|
|
|
|
|
|
|
|
|
|
|
* The <glob.h> interface has several new flags from 4.4 BSD that extend the
|
|
|
|
|
|
POSIX.2 `glob' function to do ~ and {...} expansion.
|
|
|
|
|
|
|
|
|
|
|
|
* New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD.
|
1997-01-26 13:33:35 +08:00
|
|
|
|
`clearenv' which is used in POSIX.9 is also available.
|
1996-01-02 16:57:42 +08:00
|
|
|
|
|
|
|
|
|
|
* New function `getsid' returns session ID number on systems that support it.
|
|
|
|
|
|
|
1996-03-06 05:41:30 +08:00
|
|
|
|
* We have incorporated the 4.4 BSD `db' library (version 1.85). New header
|
|
|
|
|
|
files <db.h> and <mpool.h> provide a rich set of functions for several
|
|
|
|
|
|
types of simple databases stored in memory and in files, and <ndbm.h> is
|
1996-12-20 09:39:50 +08:00
|
|
|
|
an old `ndbm'-compatible interface using the `db' functions. Link with
|
1996-07-09 01:45:03 +08:00
|
|
|
|
`-ldb' to get these functions.
|
1996-03-06 05:41:30 +08:00
|
|
|
|
|
|
|
|
|
|
* New macro `strdupa' copies a string like `strdup', but uses local stack
|
|
|
|
|
|
space from `alloca' instead of dynamic heap space from `malloc'.
|
1996-03-14 19:20:03 +08:00
|
|
|
|
|
|
|
|
|
|
* New function `strnlen' is like `strlen' but searches only a given maximum
|
1997-01-26 13:33:35 +08:00
|
|
|
|
number of characters for the null terminator. `stpncpy', `strndup' and
|
|
|
|
|
|
`strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa'
|
|
|
|
|
|
function.
|
1996-06-23 05:14:17 +08:00
|
|
|
|
|
|
|
|
|
|
* New function `statfs' in header <sys/statfs.h>.
|
|
|
|
|
|
|
|
|
|
|
|
* The new <argz.h> and <envz.h> interfaces contributed by Miles Bader
|
|
|
|
|
|
provide convenient functions for operating on blocks of null-terminated
|
|
|
|
|
|
strings.
|
|
|
|
|
|
|
|
|
|
|
|
* A new suite of functions in <utmp.h> handle all the details of reading
|
|
|
|
|
|
and writing the utmp file.
|
1997-01-26 13:33:35 +08:00
|
|
|
|
|
|
|
|
|
|
* An implementation of the NIS/YP(tm) based NSS service was contributed by
|
|
|
|
|
|
Thorsten Kukuk.
|
|
|
|
|
|
|
|
|
|
|
|
* Paul Eggert and Ulrich Drepper modified the `strftime' function to be
|
|
|
|
|
|
completely POSIX compliant and also implemented the extended functionality
|
|
|
|
|
|
to handle alternate digit representation and alternate era date formats.
|
|
|
|
|
|
|
|
|
|
|
|
* Ulrich Drepper provided an implementation of the `strptime' function
|
|
|
|
|
|
defined in XPG4.2 which transforms a string into a `struct tm' value.
|
|
|
|
|
|
|
|
|
|
|
|
* Paul Eggert provided the tzselect shell script as part of the timezone
|
|
|
|
|
|
code. The shell script makes it easy to select the correct timezone
|
|
|
|
|
|
specification.
|
|
|
|
|
|
|
|
|
|
|
|
* The implementation of the malloc family of functions is completely replaced
|
|
|
|
|
|
by a new implementation by Doug Lea with many improvements by Wolfram Gloger.
|
|
|
|
|
|
The implementation uses the mmap function (if available) and it is
|
|
|
|
|
|
optimized for the use in multi threaded programs.
|
|
|
|
|
|
|
|
|
|
|
|
* Ulrich Drepper contributed a MD5 "encryption" for the crypt family of
|
|
|
|
|
|
functions. This new functionality is usable by specifying a special
|
|
|
|
|
|
salt string and it is compatible with implementation on *BSD systems.
|
|
|
|
|
|
|
|
|
|
|
|
* Lots of functions from the XPG4.2 standard were added by Ulrich Drepper:
|
|
|
|
|
|
`getsubopt' to handle second level command line options, `bsd_signal'
|
|
|
|
|
|
to access BSD style `signal' functionality, the obsolete `regexp' style
|
|
|
|
|
|
expression matcher.
|
|
|
|
|
|
|
|
|
|
|
|
* the `lchown' function is available on system which support this
|
|
|
|
|
|
functionality.
|
|
|
|
|
|
|
|
|
|
|
|
* The implementation of the shadow password handling function was contributed
|
|
|
|
|
|
by Ulrich Drepper.
|
|
|
|
|
|
|
|
|
|
|
|
* David Mosberger-Tang changed the SunRPC implementation to be 64bit safe.
|
|
|
|
|
|
|
|
|
|
|
|
* POSIX.1g support was added. The <sys/select.h> header is available,
|
|
|
|
|
|
`isfdtype' and `pselect' are implemented. Craig Metz contributed an
|
|
|
|
|
|
implementation of `getaddrinfo'.

Version 1.09
|
|
|
|
|
|
|
|
|
|
|
|
* For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'.
|
|
|
|
|
|
|
|
|
|
|
|
* New header file <fstab.h> and new functions `getfsspec', `getfsent' and
|
|
|
|
|
|
friends, for parsing /etc/fstab. This code comes from 4.4 BSD.
|
|
|
|
|
|
|
|
|
|
|
|
* The new function `daemon' from 4.4 BSD is useful for server programs that
|
|
|
|
|
|
want to put themselves in the background.
|
|
|
|
|
|
|
|
|
|
|
|
* Joel Sherrill has contributed support for several standalone boards that
|
|
|
|
|
|
run without an operating system.
|
|
|
|
|
|
|
|
|
|
|
|
* `printf', `scanf' and friends now accept a `q' type modifier for long
|
|
|
|
|
|
long int as well as `ll'. Formats using these might be `%qu' or `%lld'.
|
|
|
|
|
|
|
|
|
|
|
|
* All of the code taken from BSD (notably most of the math and networking
|
|
|
|
|
|
routines) has been updated from the BSD 4.4-Lite release.
|
|
|
|
|
|
|
|
|
|
|
|
* The resolver code has been updated from the BIND-4.9.3-BETA9 release.
|
|
|
|
|
|
|
|
|
|
|
|
* The new functions `getdomainname' and `setdomainname' fetch or change the
|
|
|
|
|
|
YP/NIS domain name. These are system calls which exist on systems which
|
|
|
|
|
|
have YP (aka NIS).
|
|
|
|
|
|
|
|
|
|
|
|
* The time zone data files have been updated for the latest international
|
|
|
|
|
|
conventions.
|
|
|
|
|
|
|
|
|
|
|
|
* The SunRPC programs `portmap' and `rpcinfo' are now installed in
|
|
|
|
|
|
$(sbindir) (usually /usr/local/sbin) instead of $(bindir).
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.08
|
|
|
|
|
|
|
|
|
|
|
|
* The C library now includes support for Sun RPC, from Sun's free
|
|
|
|
|
|
RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs
|
|
|
|
|
|
are included. (There is still no support for YP.)
|
|
|
|
|
|
|
|
|
|
|
|
* Tom Quinn has contributed a port of the C library to SGI machines running
|
|
|
|
|
|
Irix 4 (mips-sgi-irix4).
|
|
|
|
|
|
|
|
|
|
|
|
* The new `lockf' function is a simplified interface to the locking
|
|
|
|
|
|
facilities of `fcntl', included for compatibility.
|
|
|
|
|
|
|
|
|
|
|
|
* New time functions `timegm', `timelocal', and `dysize' for compatibility.
|
|
|
|
|
|
|
|
|
|
|
|
* New header file <sys/timeb.h> and new function `ftime' for compatibility.
|
|
|
|
|
|
|
|
|
|
|
|
* New header files <poll.h> and <sys/poll.h> and new function `poll' for
|
|
|
|
|
|
compatibility.
|
|
|
|
|
|
|
|
|
|
|
|
* The error message printed by `assert' for a failed assertion now includes
|
|
|
|
|
|
the name of the program (if using GNU ld) and the name of the calling
|
|
|
|
|
|
function (with versions of GCC that support this).
|
|
|
|
|
|
|
|
|
|
|
|
* The `psignal' function is now declared in <signal.h>, not <stdio.h>.
|
|
|
|
|
|
|
|
|
|
|
|
* The library now includes the <sys/mman.h> header file and memory
|
|
|
|
|
|
management functions `mmap', `munmap', `mprotect', `msync', and
|
|
|
|
|
|
`madvise', on systems that support those facilities.
|
|
|
|
|
|
|
|
|
|
|
|
* The interface for `mcheck' has changed slightly: the function called to
|
|
|
|
|
|
abort the program when an allocation inconsistency is detected now takes
|
|
|
|
|
|
an argument that indicates the type of failure. The new function
|
|
|
|
|
|
`mprobe' lets you request a consistency check for a particular block at
|
|
|
|
|
|
any time (checks are normally done only when you call `free' or `realloc'
|
|
|
|
|
|
on a block).
|
|
|
|
|
|
|
|
|
|
|
|
* It is now possible to easily cross-compile the C library, building on one
|
|
|
|
|
|
system a library to run on another machine and/or operating system. All
|
|
|
|
|
|
you need to do is set the variable `HOST_CC' in `configparms' to the
|
|
|
|
|
|
native compiler for programs to run on the machine you are building on (a
|
|
|
|
|
|
few generator programs are used on Unix systems); set `CC' to the
|
|
|
|
|
|
cross-compiler.
|
|
|
|
|
|
|
|
|
|
|
|
* The new function `fexecve' (only implemented on the GNU system) executes
|
|
|
|
|
|
a program file given a file descriptor already open on the file.
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.07
|
|
|
|
|
|
|
|
|
|
|
|
* Brendan Kehoe has contributed most of a port to the DEC Alpha
|
|
|
|
|
|
running OSF/1 (alpha-dec-osf1). He says it is 75% complete.
|
|
|
|
|
|
|
|
|
|
|
|
* You can set the variable `libprefix' in `configparms' to specify a prefix
|
|
|
|
|
|
to be prepended to installed library files; this makes it easy to install
|
|
|
|
|
|
the GNU C library to be linked as `-lgnuc' or whatever.
|
|
|
|
|
|
|
|
|
|
|
|
* The new `stpncpy' is a cross between `stpcpy' and `strncpy': It
|
|
|
|
|
|
copies a limited number of characters from a string, and returns the
|
|
|
|
|
|
address of the last character written.
|
|
|
|
|
|
|
|
|
|
|
|
* You no longer need to check for whether the installed `stddef.h' is
|
|
|
|
|
|
compatible with the GNU C library. configure now checks for you.
|
|
|
|
|
|
|
|
|
|
|
|
* You can now define a per-stream `fileno' function to convert the
|
|
|
|
|
|
stream's cookie into an integral file descriptor.
|
|
|
|
|
|
|
|
|
|
|
|
* ``malloc (0)'' no longer returns a null pointer. Instead, it
|
|
|
|
|
|
allocates zero bytes of storage, and returns a unique pointer which
|
|
|
|
|
|
you can pass to `realloc' or `free'. The behavior is undefined if
|
|
|
|
|
|
you dereference this pointer.
|
|
|
|
|
|
|
|
|
|
|
|
* The C library now runs on Sony NEWS m68k machines running either
|
|
|
|
|
|
NewsOS 3 or NewsOS 4.
|
|
|
|
|
|
|
|
|
|
|
|
* The new `syscall' function is a system-dependent primitive function
|
|
|
|
|
|
for invoking system calls. It has the canonical behavior on Unix
|
|
|
|
|
|
systems, including unreliable return values for some calls (such as
|
|
|
|
|
|
`pipe', `fork' and `getppid').
|
|
|
|
|
|
|
|
|
|
|
|
* The error code `EWOULDBLOCK' is now obsolete; it is always defined
|
|
|
|
|
|
to `EAGAIN', which is the preferred name. On systems whose kernels
|
|
|
|
|
|
use two distinct codes, the C library now translates EWOULDBLOCK to
|
|
|
|
|
|
EAGAIN in every system call function.
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.06
|
|
|
|
|
|
|
|
|
|
|
|
* The GNU C Library Reference Manual is now distributed with the library.
|
|
|
|
|
|
`make dvi' will produce a DVI file of the printed manual.
|
|
|
|
|
|
`make info' will produce Info files that you can read on line using C-h i
|
|
|
|
|
|
in Emacs or the `info' program.

1995-02-18 09:27:10 +08:00
|
|
|
|
|
|
|
|
|
|
* The library now supports SVR4 on i386s (i386-unknown-sysv4).
|
|
|
|
|
|
|
|
|
|
|
|
* Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2.
|
|
|
|
|
|
|
|
|
|
|
|
* Jason Merrill has contributed a port to the Sequent Symmetry running
|
|
|
|
|
|
Dynix version 3 (i386-sequent-dynix).
|
|
|
|
|
|
|
|
|
|
|
|
* The library has been ported to i386s running SCO 3.2.4 (also known as SCO
|
|
|
|
|
|
ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2).
|
|
|
|
|
|
|
|
|
|
|
|
* New function `memory_warnings' lets you arrange to get warnings when
|
|
|
|
|
|
malloc is running out of memory to allocate, like Emacs gives you.
|
|
|
|
|
|
|
|
|
|
|
|
* The C library now contains the relocating allocator used in Emacs 19 for
|
|
|
|
|
|
its editing buffers. This allocator (ralloc) minimizes allocation
|
|
|
|
|
|
overhead and fragmentation by moving allocated regions around whenever it
|
|
|
|
|
|
needs to. You always refer to a ralloc'd region with a "handle" (a
|
|
|
|
|
|
pointer to a pointer--an object of type `void **').
|
|
|
|
|
|
|
|
|
|
|
|
* There is a new `printf' format: `%m' gives you the string corresponding
|
|
|
|
|
|
to the error code in `errno'.
|
|
|
|
|
|
|
|
|
|
|
|
* In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s'
|
|
|
|
|
|
or `%[' conversion, but instead of filling in a fixed-sized buffer you
|
|
|
|
|
|
pass, the `a' modifier says to fill in a `char **' you pass with a
|
|
|
|
|
|
malloc'd string.
|
|
|
|
|
|
|
|
|
|
|
|
* The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and
|
|
|
|
|
|
`FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a
|
|
|
|
|
|
name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching.
|
|
|
|
|
|
|
|
|
|
|
|
* `mkstemp' is a traditional Unix function to atomically create and open a
|
|
|
|
|
|
uniquely-named temporary file.
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.05
|
|
|
|
|
|
|
|
|
|
|
|
* The standard location for the file that says what the local timezone is
|
|
|
|
|
|
has changed again. It is now `/usr/local/etc/localtime' (or more
|
|
|
|
|
|
precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'.
|
|
|
|
|
|
|
|
|
|
|
|
* The distribution no longer contains any files with names longer than 14
|
|
|
|
|
|
characters.
|
|
|
|
|
|
|
|
|
|
|
|
* `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE.
|
|
|
|
|
|
These are set by the new `trusted' and `console' keywords in `/etc/ttys'.
|
|
|
|
|
|
|
|
|
|
|
|
* New functions `ttyslot' and `syslog' from 4.4 BSD.
|
|
|
|
|
|
|
|
|
|
|
|
Version 1.04
|
|
|
|
|
|
|
|
|
|
|
|
* The configuration process has changed quite a bit. The `configure'
|
|
|
|
|
|
script is now used just like the configuration scripts for other GNU
|
|
|
|
|
|
packages. The `sysdeps' directory hierarchy is much rearranged.
|
|
|
|
|
|
The file `INSTALL' explains the new scheme in detail.
|
|
|
|
|
|
|
|
|
|
|
|
* The header files no longer need to be processed into ANSI C and
|
|
|
|
|
|
traditional C versions. There is just one set of files to install, and
|
|
|
|
|
|
it will work with ANSI or old C compilers (including `gcc -traditional').
|
|
|
|
|
|
|
|
|
|
|
|
* Brendan Kehoe and Ian Lance Taylor have ported the library to the
|
|
|
|
|
|
MIPS DECStation running Ultrix 4.
|
|
|
|
|
|
|
|
|
|
|
|
* The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries.
|
|
|
|
|
|
Tom Quinn contributed the initial code. The GNU C library can NOT yet be
|
|
|
|
|
|
made itself into a shared library.
|
|
|
|
|
|
|
|
|
|
|
|
* Yet further improved support for the i386, running 4.3 BSD-like systems
|
|
|
|
|
|
(such as Mach 3 with the Unix single-server), or System V.
|
|
|
|
|
|
|
|
|
|
|
|
* New function `strncasecmp' to do case-insensitive string comparison
|
|
|
|
|
|
with limited length.
|
|
|
|
|
|
|
|
|
|
|
|
* New function `strsep' is a reentrant alternative to `strtok'.
|
|
|
|
|
|
|
|
|
|
|
|
* New functions `scandir' and `alphasort' for searching directories.
|
|
|
|
|
|
|
|
|
|
|
|
* New function `setenv' is a better interface to `putenv'.
|
|
|
|
|
|
|
|
|
|
|
|
* Ian Lance Taylor has contributed an implementation of the SVID `ftw'
|
|
|
|
|
|
function for traversing a directory tree.
|
|
|
|
|
|
|
|
|
|
|
|
* The GNU obstack package is now also part of the C library.
|
|
|
|
|
|
The new function `open_obstack_stream' creates a stdio stream that
|
|
|
|
|
|
writes onto an obstack; `obstack_printf' and `obstack_vprintf' do
|
|
|
|
|
|
formatted output directly to an obstack.

|
|
|
|
|
|
|
|
|
|
* Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only),
|
|
|
|
|
|
cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid.
|
|
|
|
|
|
|
|
|
|
|
|
* `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'.
|
|
|
|
|
|
|
|
|
|
|
|
* The new functions `strfry' and `memfrob' do mysterious and wonderful
|
|
|
|
|
|
things to your strings.
|
|
|
|
|
|
|
|
|
|
|
|
* There are some new test programs: test-fseek, testmb, and testrand.
|
|
|
|
|
|
|
|
|
|
|
|
* Some work has been done to begin porting the library to 4.4 BSD and Linux.
|
|
|
|
|
|
These ports are not finished, but are a good starting place for really
|
|
|
|
|
|
supporting those systems.
|
|
|
|
|
|
|
|
|
|
|
|
* `/etc/localtime' is now the standard location for the file that says what
|
|
|
|
|
|
the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'.
|
|
|
|
|
|
This follows the general principle that `/etc' is the place for all local
|
|
|
|
|
|
configuration files.
|
|
|
|
|
|
|
|
|
|
|
|
* The C library header files now use `extern "C"' when used by the C++
|
|
|
|
|
|
compiler, so the C library should now work with C++ code.
|
|
|
|
|
|
|
|
|
|
|
|
* The header file <bstring.h> is gone. <string.h> now declares bcopy,
|
Update.

bcmp, bzero, and ffs. (Update: nowadays these functions are declared
|
|
|
|
|
|
in <strings.h>.)

|
|
|
|
* Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting
|
|
|
|
|
|
function which uses the `merge sort' algorithm, and is said to be
|
|
|
|
|
|
significantly faster than the old GNU `qsort' function. Merge sort is
|
|
|
|
|
|
now the standard `qsort' function. The new algorithm can require a lot
|
|
|
|
|
|
of temporary storage; so, the old sorting function is called when the
|
|
|
|
|
|
required storage is not available.
|
|
|
|
|
|
|
|
|
|
|
|
* The C library now includes Michael Glad's Ultra Fast Crypt, which
|
|
|
|
|
|
provides the Unix `crypt' function, plus some other entry points.
|
|
|
|
|
|
|
|
|
|
|
|
* The code and header files taken from 4.4 BSD have been updated with the
|
|
|
|
|
|
latest files released from Berkeley.
