 "One of the 'small improvements all over the place' releases for us.

  It's hard to draw any direct comparisons because summer vacations
  disrupted our patch processing (and presumably - generation) quite a
  bit.

  Quick and dirty count suggests we (Paolo and I) merged a very similar
  number of net (632) and net-next (648) patches. This is not telling
  the full story either because 1/3 to 1/2 of the net-next patches also
  *seem* like AI-driven low priority fixes, cleanups and clarifications.

  We are completely overwhelmed, of course. The glimmer of hope is that
  we secured sufficient LLM budget and access (thank you Meta!) to run
  reviews with multiple frontier models on each patch. This eliminates
  some hallucinations. That said, in terms of review, the LLMs can only
  do so much.

  The sad truth is that our APIs (especially for rare events like PCIe
  errors, timeouts etc) have always been racy, and now LLMs don't let us
  ignore that. I expect our direction for the next release will be to
  tweak the reviews a little bit more, but start shifting focus to
  letting the LLMs take care of the busy work - managing patchwork,
  automating common process complaints, editing commit messages, and
  maybe applying patches which already got "reviewed-by" tags from
  people we trust...

  Core & protocols:

   - A few steps lowering rtnl_lock dependence:
      - per-netns netdev unregistration for select SW drivers (e.g.
        veth, ipvlan, tunnels)
      - rtnl_lock-less FIB rule changes (RTM_NEWRULE and RTM_DELRULE)
      - prepare software drivers and TC qdiscs for rtnl_lock-less GET

   - Support BIG TCP (>64kB TSO) in UDP tunnels (vxlan, geneve)

   - Report the per-group user count via RTM_GETMULTICAST

   - Expose the route deletion reason in RTM_DELROUTE

   - Add a SO_RIGHTS_NOTRUNC option to UNIX sockets to enable more

Pull bpf updates from Daniel Borkmann:
 "Major changes:

   - Redesign the verifier error reporting: failures now carry source
     and instruction annotations along with the causal event history
     that led to them, making program rejections far easier to debug and
     repair (Kumar Kartikeya Dwivedi)

   - Add arena argument support to kfuncs and struct_ops through the new
     __arena and __arena__nullable suffixes (Tejun Heo, Puranjay Mohan,
     Kumar Kartikeya Dwivedi, Ihor Solodrai)

   - Signed BPF program loader rework to accommodate both BPF and
     security community needs where the kernel runs the signature
     verification at BPF_PROG_LOAD time before the LSM admission hook
     (Daniel Borkmann)

   - Add a set of ksock kfuncs which let BPF LSM and syscall programs
     create, connect and send on UDP sockets in order to emit telemetry
     data (Mahe Tardy)

   - Unify helper and kfunc call argument verification and classify
     kfunc arguments purely from BTF into a generated bpf_func_proto
     which is computed once at add-call time (Amery Hung)

  Other features and fixes:

   - Enable EXECMEM_ROX_CACHE for BPF allocations on x86 (Mike Rapoport)

   - Add bidirectional VLAN support to bpf_fib_lookup() through the new
     BPF_FIB_LOOKUP_VLAN and BPF_FIB_LOOKUP_VLAN_INPUT flags (Avinash
     Duduskar)

   - Infer zext_dst from static register liveness analysis to fix 32-bit
     zero-extension semantics, and remove the artificial limitations on
     pointer types eligible for spilling (Eduard Zingerman)

   - Inline the numeric open-coded iterator kfuncs so that bpf_for()
     loops no longer pay a kfunc call on every iteration (Puranjay
     Mohan)

   - Add an arena-based bitmap data structure to libarena along with
     serial and parallel selftests (Emil Tsalapatis)

   - Teach resolve_btfids to discover kfuncs from the kernel's BTF ID
     sets and to emit kfunc BTF decl tags, reducing the kernel build's
     dependency on pahole features (Ihor Solodrai)

   - Add BPF_F_ADJ_ROOM_DECAP_* flags to bpf_skb_adjust_room() so that
     tunnel decapsulation can update the GSO and encapsulation state of
     the skb (Nick Hudson)

   - Fix the ring buffer pending_pos walk and the available-data
     accounting on 32-bit position wrap (Israel Téllez García)

   - Add memory usage accounting for arena maps and fix an mmap_lock
     deadlock on arena lock failure (Jiayuan Chen)

   - Add tracing_multi link info support to the kernel UAPI and bpftool,
     and refactor the stack map code to run with preemption disabled
     (Jiri Olsa)

   - Support BPF_F_EGRESS in bpf_redirect_peer() to emit the skb in the
     egress direction of the target's peer device (Jordan Rife)

   - Add a KF_SPINLOCK_SAFE kfunc flag so that providers, in particular
     modules, can declare kfuncs safe to call under bpf_spin_lock
     instead of relying on the verifier's hard-coded allowlist (Kaitao
     Cheng)

   - Introduce global percpu data for BPF programs with libbpf probing
     and bpftool skeleton support, and stop exposing uninitialized
     kernel heap memory when copying per-CPU map values (Leon Hwang)

   - Add s390 JIT support for load-acquire and store-release
     instructions (Maxim Khmelevskii)

   - Fix a CFI mismatch in the task work callback and an arm64 KASAN
     false positive after bpf_throw() (Mykyta Yatsenko)

   - Reject writes through untrusted BTF pointers and bound the
     rdonly/rdwr_buf_size kfunc arguments (Nicholas Dudar)

   - Invalidate RCU pointers only after the final spin unlock and
     account for preempt and IRQ disabled regions as overlapping RCU
     protection (Ning Ding)

   - Support mixing bpf2bpf calls and tail calls on RV64, add signed
     operations and 32-bit atomics to the RV32 JIT, and add timed
     may_goto support (Pu Lehui, Kuan-Wei Chiu, Feng Jiang)

   - Fix a use-after-free on mm_struct in bpf_find_vma() for foreign
     tasks and an mmap_lock leak in the irq_work path (Sanghyun Park)

   - Populate mmap-able BPF array map memory lazily which makes mmap()
     O(1) instead of proportional to the map size (Song Liu)

   - Introduce a jit_required flag and reject programs with inlined
     helpers when no JIT is available, where the interpreter would
     otherwise jump into an invalid address (Tiezhu Yang)

   - Fix the x86 JIT per-CPU address resolution into an extended
     register where the REX prefix dropped the high destination register
     bit (Vineet Gupta)

   - Reject MEM_ALLOC BTF accesses past object bounds, arena frees below
     the arena base, and mixed arena and ordinary atomic paths (Yiyang
     Chen)

   - Fix the trampoline handling of 128-bit arguments and of return
     values larger than 8 bytes (Yonghong Song)

   - Ensure that any fault prone load is rewritten with exception table
     handling, and fix the arena load-acquire and atomic fetch handling
     in the x86, arm64, riscv and s390 JITs (Daniel Borkmann)

   - Many more fixes and cleanups across the verifier, arena,
     trampolines, sockmap, cgroup, ring buffer, x86/arm64/riscv/s390
     JITs, libbpf, bpftool, resolve_btfids and selftests"

Pull timer and timekeeping core updates from Thomas Gleixner:

 - Fix a subtly inconsistency in the timekeeping code, which fails to
   account for the monotonicity adjustment in ntp_error.

   For small changes of the clocksource multiplicator (+/-1) which are
   typically used by the NTP PLL this is hard to observe. But for larger
   adjustments, e.g. caused by a direct frequency setting through
   adjtimex() the one-time uncompensated offset is significant.

   Cure this by adjusting ntp_error with the resulting offset so that
   the discrepancy is smoothed away over time

 - Make tick length calculations correct in NTP.

   The timekeeping core takes the quantisation of the clocksource into
   account when calculating the tick length to compensate for the
   deviation of the nominal NTP_INTERVAL_LENGTH.

   While timekeeping gets this right, NTP is not aware of that, which
   means it operates on the nominal value and not on the actual value
   which is determined by the clock source frequency. The rounding of a
   coarse clocksource like the ACPI PM timer results in a +127 PPM
   deviation.

   Cure this by exposing the deviation to the NTP code so that it can
   operate on the same data as the timekeeping core. This is purely
   kernel internal. User space still sees the nominal tick lenght via
   adjtimex().

 - The accuracy of the NTP adjustments is fairly approximate as the code
   assumes that the invocations are precisely in NTP interval frequency
   ticks and the final adjustment can over and under-run.

   Cure this by adjusting ntp_error by the intended skew on each tick to
   achieve the desired rate.

 - Handle the two competing skews of time offset and time adjustment
   correctly by calculating the conflict portion between the skews and
   adjusting both accordingly.

 - A set of updates and improvements for the selftests

 - The usual small fixes and improvements all over the place

Pull fscrypt updates from Eric Biggers:
 "The main change this cycle is a significant simplification that's been
  overdue for a while now: standardizing on a single file contents
  encryption implementation in ext4 and f2fs, instead of having two.

  Specifically, the original filesystem-layer file contents encryption
  implementation is removed, and the blk-crypto implementation is now
  used unconditionally. blk-crypto delegates either to inline crypto
  hardware or to the CPU via blk-crypto-fallback. The latter is
  functionally equivalent to the original filesystem-layer code.

  The blk-crypto implementation already existed, but previously it was
  used only when the filesystem was mounted with "-o inlinecrypt". Now,
  "-o inlinecrypt" just selects whether inline crypto hardware is used.

  To allow maintaining that user control over hardware use, the
  blk-crypto API is extended with a new flag BLK_CRYPTO_CFG_ALLOW_HW.

  Overall, this removes quite a bit of redundant code from ext4, f2fs,
  and fs/crypto/. It should make things easier for ongoing filesystem
  efforts such as iomap support, large folios, and btrfs encryption
  (btrfs had already been planning to use blk-crypto exclusively.)

  There are two small behavior changes of note:

   - Direct I/O now works on encrypted files even without "-o inlinecrypt",
     rather than falling back to buffered I/O. This is effectively a
     bugfix, though I'll continue to keep an eye out for any user that
     may have been depending on the buffered I/O fallback.

   - IV_INO_LBLK_32 policies are no longer supported in certain cases
     that didn't make sense and have no known uses.

  This has been in linux-next since July 22 with no reported issues. All
  encryption xfstests pass on ext4 and f2fs. As usual I've also been
  using it on a system with an fscrypt-encrypted home directory. Of
  course, the blk-crypto code paths also aren't new and were already
  being used on many systems via the inlinecrypt mount option.

  In addition to the main change described above, there are a few other
  cleanups such as using lock guards for mutexes, improving
  documentation, and removing a workaround for outdated gcc versions"
