Subject: [GIT PULL] BPF changes for 6.18
Hi Linus,
The following changes since commit e59a039119c3ec241228adf12dca0dd4398104d0:
Merge tag 's390-6.17-4' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux (2025-09-11 08:46:30 -0700)
are available in the Git repository at:

libbpf: Replace AF_ALG with open coded SHA-256 (2025-09-28 04:25:31 -0700)
----------------------------------------------------------------
Note, there is a trivial conflict between tip and bpf-next trees:
in kernel/events/uprobes.c between commit:
4363264111e12 ("uprobe: Do not emulate/sstep original instruction when ip is changed")
from the bpf-next tree and commit:
ba2bfc97b4629 ("uprobes/x86: Add support to optimize uprobes")
from the tip tree:
https://lore.kernel.org/all/aNVMR5rjA2geHNLn@sirena.org.uk/
since Jiri's two separate uprobe/bpf related patch series landed
in different trees. One was mostly uprobe. Another was mostly bpf.
Other than that the main changes are:
- Support pulling non-linear xdp data with bpf_xdp_pull_data() kfunc
(Amery Hung).
Applied as a stable branch in bpf-next and net-next trees.
- Support reading skb metadata via bpf_dynptr (Jakub Sitnicki).
Also a stable branch in bpf-next and net-next trees.
- Enforce expected_attach_type for tailcall compatibility
(Daniel Borkmann)
- Replace path-sensitive with path-insensitive live stack analysis
in the verifier (Eduard Zingerman).
This is a significant change in the verification logic. More details,
motivation, long term plans are in the cover letter/merge commit.
- Support signed BPF programs (KP Singh).
This is another major feature that took years to materialize.
Algorithm details are in the cover letter/marge commit.
- Add support for may_goto instruction to s390 JIT (Ilya Leoshkevich)
- Add support for may_goto instruction to arm64 JIT (Puranjay Mohan)
- Fix USDT SIB argument handling in libbpf (Jiawei Zhao)
- Allow uprobe-bpf program to change context registers (Jiri Olsa)
- Support signed loads from BPF arena (Kumar Kartikeya Dwivedi
and Puranjay Mohan)
- Allow access to union arguments in tracing programs (Leon Hwang)
- Optimize rcu_read_lock() + migrate_disable() combination
where it's used in BPF subsystem (Menglong Dong)
- Introduce bpf_task_work_schedule*() kfuncs to schedule
deferred execution of BPF callback in the context of
a specific task using the kernel’s task_work infrastructure
(Mykyta Yatsenko)
- Enforce RCU protection for KF_RCU_PROTECTED kfuncs
(Kumar Kartikeya Dwivedi)
- Add stress test for rqspinlock in NMI
(Kumar Kartikeya Dwivedi)
- Improve the precision of tnum multiplier verifier operation
(Nandakumar Edamana)
- Use tnums to improve is_branch_taken() logic (Paul Chaignon)
- Add support for atomic operations in arena in riscv JIT (Pu Lehui)
- Report arena faults to BPF error stream (Puranjay Mohan)
- Search for tracefs at /sys/kernel/tracing first in bpftool
(Quentin Monnet)
- Add bpf_strcasecmp() kfunc (Rong Tao)
- Support lookup_and_delete_elem command in BPF_MAP_STACK_TRACE
(Tao Chen)
