Networking changes for 6.10.
Core & protocols
----------------
- Complete rework of garbage collection of AF_UNIX sockets.
AF_UNIX is prone to forming reference count cycles due to fd passing
functionality. New method based on Tarjan's Strongly Connected Components
algorithm should be both faster and remove a lot of workarounds
we accumulated over the years.
- Add TCP fraglist GRO support, allowing chaining multiple TCP packets
and forwarding them together. Useful for small switches / routers which
lack basic checksum offload in some scenarios (e.g. PPPoE).
- Support using SMP threads for handling packet backlog i.e. packet
processing from software interfaces and old drivers which don't
use NAPI. This helps move the processing out of the softirq jumble.
- Continue work of converting from rtnl lock to RCU protection.
Don't require rtnl lock when reading: IPv6 routing FIB, IPv6 address
labels, netdev threaded NAPI sysfs files, bonding driver's sysfs files,
MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics, TC Qdiscs,
neighbor entries, ARP entries via ioctl(SIOCGARP), a lot of the link
information available via rtnetlink.
- Small optimizations from Eric to UDP wake up handling, memory accounting,
RPS/RFS implementation, TCP packet sizing etc.
- Allow direct page recycling in the bulk API used by XDP, for +2% PPS.
- Support peek with an offset on TCP sockets.
- Add MPTCP APIs for querying last time packets were received/sent/acked,
and whether MPTCP "upgrade" succeeded on a TCP socket.
- Add intra-node communication shortcut to improve SMC performance.
- Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol driver.
- Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver.
- Add reset reasons for tracing what caused a TCP reset to be sent.
- Introduce direction attribute for xfrm (IPSec) states.
State can be used either for input or output packet processing.
Things we sprinkled into general kernel code
--------------------------------------------
- Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS().
This required touch-ups and renaming of a few existing users.
- Add Endian-dependent __counted_by_{le,be} annotations.
- Make building selftests "quieter" by printing summaries like
"CC object.o" rather than full commands with all the arguments.
Netfilter
---------
- Use GFP_KERNEL to clone elements, to deal better with OOM situations
and avoid failures in the .commit step.
BPF
---
- Add eBPF JIT for ARCv2 CPUs.
- Support attaching kprobe BPF programs through kprobe_multi link in
a session mode, meaning, a BPF program is attached to both function entry
and return, the entry program can decide if the return program gets
executed and the entry program can share u64 cookie value with return
program. "Session mode" is a common use-case for tetragon and bpftrace.
- Add the ability to specify and retrieve BPF cookie for raw tracepoint
programs in order to ease migration from classic to raw tracepoints.
- Add an internal-only BPF per-CPU instruction for resolving per-CPU
memory addresses and implement support in x86, ARM64 and RISC-V JITs.
This allows inlining functions which need to access per-CPU state.
- Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
atomics in bpf_arena which can be JITed as a single x86 instruction.
Support BPF arena on ARM64.
- Add a new bpf_wq API for deferring events and refactor process-context
bpf_timer code to keep common code where possible.
- Harden the BPF verifier's and/or/xor value tracking.
- Introduce crypto kfuncs to let BPF programs call kernel crypto APIs.
- Support bpf_tail_call_static() helper for BPF programs with GCC 13.
- Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
program to have code sections where preemption is disabled.
Driver API
----------
- Skip software TC processing completely if all installed rules are
marked as HW-only, instead of checking the HW-only flag rule by rule.
- Add support for configuring PoE (Power over Ethernet), similar to
the already existing support for PoDL (Power over Data Line) config.
- Initial bits of a queue control API, for now allowing a single queue
to be reset without disturbing packet flow to other queues.
- Common (ethtool) statistics for hardware timestamping.
Tests and tooling
-----------------
- Remove the need to create a config file to run the net forwarding tests
so that a naive "make run_tests" can exercise them.
- Define a method of writing tests which require an external endpoint
to communicate with (to send/receive data towards the test machine).
Add a few such tests.
- Create a shared code library for writing Python tests. Expose the YAML
Netlink library from tools/ to the tests for easy Netlink access.
- Move netfilter tests under net/, extend them, separate performance tests
from correctness tests, and iron out issues found by running them
"on every commit".
- Refactor BPF selftests to use common network helpers.
- Further work filling in YAML definitions of Netlink messages for:
nftables, team driver, bonding interfaces, vlan interfaces, VF info,
TC u32 mark, TC police action.
- Teach Python YAML Netlink to decode attribute policies.
- Extend the definition of the "indexed array" construct in the specs
to cover arrays of scalars rather than just nests.
- Add hyperlinks between definitions in generated Netlink docs.
Drivers
-------
- Make sure unsupported flower control flags are rejected by drivers,
and make more drivers report errors directly to the application rather
than dmesg (large number of driver changes from Asbjørn Sloth Tønnesen).
- Ethernet high-speed NICs:
- Broadcom (bnxt):

arm64 updates for 6.10
ACPI:
* Support for the Firmware ACPI Control Structure (FACS) signature
feature which is used to reboot out of hibernation on some systems.
Kbuild:
* Support for building Flat Image Tree (FIT) images, where the kernel
Image is compressed alongside a set of devicetree blobs.
Memory management:
* Optimisation of our early page-table manipulation for creation of the
linear mapping.
* Support for userfaultfd write protection, which brings along some nice
cleanups to our handling of invalid but present ptes.
* Extend our use of range TLBI invalidation at EL1.
Perf and PMUs:
* Ensure that the 'pmu->parent' pointer is correctly initialised by PMU
drivers.
* Avoid allocating 'cpumask_t' types on the stack in some PMU drivers.
* Fix parsing of the CPU PMU "version" field in assembly code, as it
doesn't follow the usual architectural rules.
* Add best-effort unwinding support for USER_STACKTRACE
* Minor driver fixes and cleanups.
Selftests:
* Minor cleanups to the arm64 selftests (missing NULL check, unused
variable).
Miscellaneous
* Add a command-line alias for disabling 32-bit application support.
* Add part number for Neoverse-V2 CPUs.
* Minor fixes and cleanups.

value that is an 8+8+8 bit concatenation of the vendor/family/model
value, and add macros that work on VFM values. This simplifies the
addition of new Intel models & families, and simplifies existing
enumeration & quirk code.
- Add support for the AMD 0x80000026 leaf, to better parse topology
information.
- Optimize the NUMA allocation layout of more per-CPU data structures
- Improve the workaround for AMD erratum 1386
- Clear TME from /proc/cpuinfo as well, when disabled by the firmware
- Improve x86 self-tests
- Extend the mce_record tracepoint with the ::ppin and ::microcode fields
- Implement recovery for MCE errors in TDX/SEAM non-root mode
- Misc cleanups and fixes

ynl: ensure exact-len value is resolved
For type String and Binary we are currently usinig the exact-len limit value as is without attempting any name resolution. However, the spec may specify the name of a constant rather than an actual value, which would result in using the constant name as is and thus break the policy. Ensure the limit value is passed to get_limit(), which will always attempt resolving the name before printing the policy rule.

Joachim kindly merged the IPv6 support in https://github.com/troglobit/mtools/pull/2, so we can just use his version now. A few more fixes subsequently came in for IPv6, so even better.

Pull misc vfs updates from Christian Brauner:
"This contains the usual miscellaneous features, cleanups, and fixes
for vfs and individual fses.
Features:
- Free up FMODE_* bits. I've freed up bits 6, 7, 8, and 24. That
means we now have six free FMODE_* bits in total (but bit #6
already got used for FMODE_WRITE_RESTRICTED)
- Add FOP_HUGE_PAGES flag (follow-up to FMODE_* cleanup)
- Add fd_raw cleanup class so we can make use of automatic cleanup
provided by CLASS(fd_raw, f)(fd) for O_PATH fds as well
- Optimize seq_puts()
- Simplify __seq_puts()
- Add new anon_inode_getfile_fmode() api to allow specifying f_mode
instead of open-coding it in multiple places
- Annotate struct file_handle with __counted_by() and use
struct_size()
- Warn in get_file() whether f_count resurrection from zero is
attempted (epoll/drm discussion)
- Folio-sophize aio
- Export the subvolume id in statx() for both btrfs and bcachefs
- Relax linkat(AT_EMPTY_PATH) requirements
- Add F_DUPFD_QUERY fcntl() allowing to compare two file descriptors
for dup*() equality replacing kcmp()
Cleanups:
- Compile out swapfile inode checks when swap isn't enabled
- Use (1 << n) notation for FMODE_* bitshifts for clarity
- Remove redundant variable assignment in fs/direct-io
- Cleanup uses of strncpy in orangefs
- Speed up and cleanup writeback
- Move fsparam_string_empty() helper into header since it's currently
open-coded in multiple places
- Add kernel-doc comments to proc_create_net_data_write()
- Don't needlessly read dentry->d_flags twice
Fixes:
- Fix out-of-range warning in nilfs2
- Fix ecryptfs overflow due to wrong encryption packet size
calculation
- Fix overly long line in xfs file_operations (follow-up to FMODE_*
cleanup)
- Don't raise FOP_BUFFER_{R,W}ASYNC for directories in xfs (follow-up
to FMODE_* cleanup)
- Don't call xfs_file_open from xfs_dir_open (follow-up to FMODE_*
cleanup)
- Fix stable offset api to prevent endless loops
- Fix afs file server rotations
- Prevent xattr node from overflowing the eraseblock in jffs2
- Move fdinfo PTRACE_MODE_READ procfs check into the .permission()
operation instead of .open() operation since this caused userspace
regressions"

bpf: make list_for_each_entry portable
[Changes from V1:
- The __compat_break has been abandoned in favor of
a more readable can_loop macro that can be used anywhere, including
loop conditions.]
The macro list_for_each_entry is defined in bpf_arena_list.h as
follows:
#define list_for_each_entry(pos, head, member) \
for (void * ___tmp = (pos = list_entry_safe((head)->first, \
typeof(*(pos)), member), \
(void *)0); \
pos && ({ ___tmp = (void *)pos->member.next; 1; }); \
cond_break, \
pos = list_entry_safe((void __arena *)___tmp, typeof(*(pos)), member))
The macro cond_break, in turn, expands to a statement expression that
contains a `break' statement. Compound statement expressions, and the
subsequent ability of placing statements in the header of a `for'
loop, are GNU extensions.
Unfortunately, clang implements this GNU extension differently than
GCC:
- In GCC the `break' statement is bound to the containing "breakable"
context in which the defining `for' appears. If there is no such
context, GCC emits a warning: break statement without enclosing `for'
o `switch' statement.
- In clang the `break' statement is bound to the defining `for'. If
the defining `for' is itself inside some breakable construct, then
clang emits a -Wgcc-compat warning.
This patch adds a new macro can_loop to bpf_experimental, that
implements the same logic than cond_break but evaluates to a boolean
expression. The patch also changes all the current instances of usage
of cond_break withing the header of loop accordingly.
Tested in bpf-next master.
No regressions.

bpf: ignore expected GCC warning in test_global_func10.c
The BPF selftest global_func10 in progs/test_global_func10.c contains:
struct Small {
long x;
};
struct Big {
long x;
long y;
};
[...]
__noinline int foo(const struct Big *big)
{
if (!big)
return 0;
return bpf_get_prandom_u32() < big->y;
}
[...]
SEC("cgroup_skb/ingress")
__failure __msg("invalid indirect access to stack")
int global_func10(struct __sk_buff *skb)
{
const struct Small small = {.x = skb->len };
return foo((struct Big *)&small) ? 1 : 0;
}
GCC emits a "maybe uninitialized" warning for the code above, because
it knows `foo' accesses `big->y'.
Since the purpose of this selftest is to check that the verifier will
fail on this sort of invalid memory access, this patch just silences
the compiler warning.
Tested in bpf-next master.
No regressions.

bpf: disable strict aliasing in test_global_func9.c
The BPF selftest test_global_func9.c performs type punning and breaks
srict-aliasing rules.
In particular, given:
int global_func9(struct __sk_buff *skb)
{
int result = 0;
[...]
{
const struct C c = {.x = skb->len, .y = skb->family };
result |= foo((const struct S *)&c);
}
}
When building with strict-aliasing enabled (the default) the
initialization of `c' gets optimized away in its entirely:
[... no initialization of `c' ...]
r1 = r10
r1 += -40
call foo
w0 |= w6
Since GCC knows that `foo' accesses s->x, we get a "maybe
uninitialized" warning.
On the other hand, when strict-aliasing is disabled GCC only optimizes
away the store to `.y':
r1 = *(u32 *) (r6+0)
*(u32 *) (r10+-40) = r1 ; This is .x = skb->len in `c'
r1 = r10
r1 += -40
call foo
w0 |= w6
In this case the warning is not emitted, because s-> is initialized.
This patch disables strict aliasing in this test when building with
GCC. clang seems to not optimize this particular code even when
strict aliasing is enabled.
Tested in bpf-next master.

selftests/bpf: Fix a few tests for GCC related warnings.
This patch corrects a few warnings to allow selftests to compile for
GCC.
-- progs/cpumask_failure.c --
progs/bpf_misc.h:136:22: error: ‘cpumask’ is used uninitialized
[-Werror=uninitialized]
136 | #define __sink(expr) asm volatile("" : "+g"(expr))
| ^~~
progs/cpumask_failure.c:68:9: note: in expansion of macro ‘__sink’
68 | __sink(cpumask);
The macro __sink(cpumask) with the '+' contraint modifier forces the
the compiler to expect a read and write from cpumask. GCC detects
that cpumask is never initialized and reports an error.
This patch removes the spurious non required definitions of cpumask.
-- progs/dynptr_fail.c --
progs/dynptr_fail.c:1444:9: error: ‘ptr1’ may be used uninitialized
[-Werror=maybe-uninitialized]
1444 | bpf_dynptr_clone(&ptr1, &ptr2);
Many of the tests in the file are related to the detection of
uninitialized pointers by the verifier. GCC is able to detect possible
uninitialized values, and reports this as an error.
The patch initializes all of the previous uninitialized structs.
-- progs/test_tunnel_kern.c --
progs/test_tunnel_kern.c:590:9: error: array subscript 1 is outside
array bounds of ‘struct geneve_opt[1]’ [-Werror=array-bounds=]
590 | *(int *) &gopt.opt_data = bpf_htonl(0xdeadbeef);
| ^~~~~~~~~~~~~~~~~~~~~~~
progs/test_tunnel_kern.c:575:27: note: at offset 4 into object ‘gopt’ of
size 4
575 | struct geneve_opt gopt;
This tests accesses beyond the defined data for the struct geneve_opt
which contains as last field "u8 opt_data[0]" which clearly does not get
reserved space (in stack) in the function header. This pattern is
repeated in ip6geneve_set_tunnel and geneve_set_tunnel functions.
GCC is able to see this and emits a warning.
The patch introduces a local struct that allocates enough space to
safely allow the write to opt_data field.
-- progs/jeq_infer_not_null_fail.c --
progs/jeq_infer_not_null_fail.c:21:40: error: array subscript ‘struct
bpf_map[0]’ is partly outside array bounds of ‘struct <anonymous>[1]’
[-Werror=array-bounds=]

| ^~
progs/jeq_infer_not_null_fail.c:14:3: note: object ‘m_hash’ of size 32
14 | } m_hash SEC(".maps");
This example defines m_hash in the context of the compilation unit and
casts it to struct bpf_map which is much smaller than the size of struct
bpf_map. It errors out in GCC when it attempts to access an element that
would be defined in struct bpf_map outsize of the defined limits for
m_hash.
This patch disables the warning through a GCC pragma.
This changes were tested in bpf-next master selftests without any
regressions.

bpf: avoid gcc overflow warning in test_xdp_vlan.c
This patch fixes an integer overflow warning raised by GCC in
xdp_prognum1 of progs/test_xdp_vlan.c:
GCC-BPF [test_maps] test_xdp_vlan.bpf.o
progs/test_xdp_vlan.c: In function 'xdp_prognum1':
progs/test_xdp_vlan.c:163:25: error: integer overflow in expression
'(short int)(((__builtin_constant_p((int)vlan_hdr->h_vlan_TCI)) != 0
? (int)(short unsigned int)((short int)((int)vlan_hdr->h_vlan_TCI
<< 8 >> 8) << 8 | (short int)((int)vlan_hdr->h_vlan_TCI << 0 >> 8
<< 0)) & 61440 : (int)__builtin_bswap16(vlan_hdr->h_vlan_TCI)
& 61440) << 8 >> 8) << 8' of type 'short int' results in '0' [-Werror=overflow]
163 | bpf_htons((bpf_ntohs(vlan_hdr->h_vlan_TCI) & 0xf000)
| ^~~~~~~~~
The problem lies with the expansion of the bpf_htons macro and the
expression passed into it. The bpf_htons macro (and similarly the
bpf_ntohs macro) expand to a ternary operation using either
__builtin_bswap16 or ___bpf_swab16 to swap the bytes, depending on
whether the expression is constant.
For an expression, with 'value' as a u16, like:
bpf_htons (value & 0xf000)
The entire (value & 0xf000) is 'x' in the expansion of ___bpf_swab16
and we get as one part of the expanded swab16:
((__u16)(value & 0xf000) << 8 >> 8 << 8
This will always evaluate to 0, which is intentional since this
subexpression deals with the byte guaranteed to be 0 by the mask.
However, GCC warns because the precise reason this always evaluates to 0
is an overflow. Specifically, the plain 0xf000 in the expression is a
signed 32-bit integer, which causes 'value' to also be promoted to a
signed 32-bit integer, and the combination of the 8-bit left shift and
down-cast back to __u16 results in a signed overflow (really a 'warning:
overflow in conversion from int to __u16' which is propegated up through
the rest of the expression leading to the ultimate overflow warning
above), which is a valid warning despite being the intended result of
this code.
Clang does not warn on this case, likely because it performs constant
folding later in the compilation process relative to GCC. It seems that
by the time clang does constant folding for this expression, the side of
the ternary with this overflow has already been discarded.
Fortunately, this warning is easily silenced by simply making the 0xf000
mask explicitly unsigned. This has no impact on the result.

selftests/bpf: Remove redundant sendmsg test cases
Remove these test cases completely, as the same behavior is already covered by other sendmsg* test cases in prog_tests/sock_addr.c. This just rewrites the destination address similar to sendmsg_v4_prog and sendmsg_v6_prog.

selftests/bpf: Handle SYSCALL_EPERM and SYSCALL_ENOTSUPP test cases
In preparation to move test cases from bpf/test_sock_addr.c that expect system calls to return ENOTSUPP or EPERM, this patch propagates errno from relevant system calls up to test_sock_addr() where the result can be checked.

selftests/bpf: Handle ATTACH_REJECT test cases
In preparation to move test cases from bpf/test_sock_addr.c that expect ATTACH_REJECT, this patch adds BPF_SKEL_FUNCS_RAW to generate load and destroy functions that use bpf_prog_attach() to control the attach_type. The normal load functions use bpf_program__attach_cgroup which does not have the same degree of control over the attach type, as bpf_program_attach_fd() calls bpf_link_create() with the attach type extracted from prog using bpf_program__expected_attach_type(). It is currently not possible to modify the attach type before bpf_program__attach_cgroup() is called, since bpf_program__set_expected_attach_type() has no effect after the program is loaded.

selftests/bpf: Use program name for skel load/destroy functions
In preparation to migrate tests from bpf/test_sock_addr.c to sock_addr.c, update BPF_SKEL_FUNCS so that it generates functions based on prog_name instead of skel_name. This allows us to differentiate between programs in the same skeleton.

selftests/bpf: Migrate recvmsg* return code tests to verifier_sock_addr.c
This set of tests check that the BPF verifier rejects programs with invalid return codes (recvmsg4 and recvmsg6 hooks can only return 1). This patch replaces the tests in test_sock_addr.c with verifier_sock_addr.c, a new verifier prog_tests for sockaddr hooks, in a step towards fully retiring test_sock_addr.c.

As reported by Kernel Test Robot and Sean Christopherson, some tests fail since v6.9-rc1 . This is due to the use of vfork() which introduced some side effects. Similarly, while making it more generic, a previous commit made some Landlock file system tests flaky, and subject to the host's file system mount configuration. This fixes all these side effects by replacing vfork() with clone3() and CLONE_VFORK, which is cleaner (no arbitrary shared memory) and makes the Kselftest framework more robust" Link: https://lore.kernel.org/oe-lkp/202403291015.1fcfa957-oliver.sang@intel.com Link: https://lore.kernel.org/r/ZjPelW6-AbtYvslu@google.com Link: https://lore.kernel.org/r/20240511171445.904356-1-mic@digikod.net * tag 'kselftest-fix-vfork-2024-05-12' of git://git.kernel.org/pub/scm/linux/kernel/git/mic/linux: selftests/harness: Handle TEST_F()'s explicit exit codes selftests/harness: Fix vfork() side effects selftests/harness: Share _metadata between forked processes selftests/pidfd: Fix wrong expectation selftests/harness: Constify fixture variants selftests/landlock: Do not allocate memory in fixture data selftests/harness: Fix interleaved scheduling leading to race conditions selftests/harness: Fix fixture teardown selftests/landlock: Fix FS tests when run on a private mount point selftests/pidfd: Fix config for pidfd_setns_test |
