05598a0907 In sem_open.c, pad was not initialized when __HAVE_64B_ATOMICS was
true.  On some arches this caused valgrind to warn about uninitialized
bytes when the struct was written to the file system.

This patch moves the initialization of pad outside of the
conditional.

06ab719d30 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.

The previous __libc_use_alloca check was incorrect because it did not

it would underestimate the stack space being used by roughly a factor
of two.

1760daadda Fix bug-strspn1.c, bug-strpbrk1.c build with GCC mainline.

bug-strspn1.c:14:3: error: right-hand operand of comma expression has no effect [-Werror=unused-value]
   strspn (b++, "");
   ^~~~~~~~~~~~~~~~

and a similar error for bug-strpbrk1.c.  I'm not sure what GCC change
introduced this, and the wording of the message is a bit off (in the
source it's not a comma expression, that must reflect GCC's IR).  But
the warning is correct (strspn is a pure function, the call is
useless, and if there wasn't an argument with a side effect much older
GCC would have warned); the point of the test is to verify that the
side effect in an argument still occurs for this useless call that can
otherwise be optimized to an (unused) constant (testing for a bug
there once was in an old strspn macro).  This patch duly arranges for
the warning to be disabled for this code.

Tested with build-many-glibcs.py for aarch64-linux-gnu.

646c2833ee Fix scanf rounding of negative floating-point numbers (bug 23280).
As reported in bug 23280, scanf functions produce incorrectly rounded
result for floating-point formats in FE_UPWARD and FE_DOWNWARD modes,
because they pass the input with sign removed to strtod functions, and
then negate the result if there was a '-' at the start of the input.

This patch fixes this by arranging for the sign to be passed to strtod
rather than scanf doing the negation itself.  In turn, keeping the
sign around in the buffer being built up for strtod requires updating
places that examine char_buffer_size (&charbuf) to allow for the sign
being there as an extra character.

Tested for x86_64.

91b2f3e5dd Update MAP_TYPE value for hppa from Linux 4.17.
This patch updates the hppa definition of MAP_TYPE to reflect a
corresponding change in the Linux kernel in 4.17 (so the value now has
four bits set, as it does on other architectures, although they are
different from other architectures because of hppa differences in
other MAP_* bits).

Tested with build-many-glibcs.py for hppa.

	* sysdeps/unix/sysv/linux/hppa/bits/mman.h [__USE_MISC]
	(MAP_TYPE): Change value to 0x2b.

809dc95d14 Fix powerpc64le build of nan-sign tests (bug 23303).
My recent nan-sign tests fail to build for powerpc64le with GCC 8
because of the special compile / link options needed there for any
test using _Float128.  This patch arranges for these tests to be
handled on powerpc64le similarly to other such tests.

Tested with build-many-glibcs.py for powerpc64le.

35ebb6b0c4 Ignore -Wrestrict for one strncat test.
With current GCC mainline, one strncat test involving a size close to
SIZE_MAX results in a -Wrestrict warning that that buffer size would
imply that the two buffers must overlap.  This patch fixes the build
by adding disabling of -Wrestrict (for GCC versions supporting that
option) to the already-present disabling of -Wstringop-overflow= and
-Warray-bounds for this test.

Tested with build-many-glibcs.py that this restores the testsuite
build with GCC mainline for aarch64-linux-gnu.

	* string/tester.c (test_strncat) [__GNUC_PREREQ (7, 0)]: Also
	ignore -Wrestrict for one test.
