Merge tag 'bpf-next-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next

Merge tag 'bpf-next-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next

Pull bpf updates from Alexei Starovoitov:

- Introduce '__attribute__((bpf_fastcall))' for helpers and kfuncs with
corresponding support in LLVM.

It is similar to existing 'no_caller_saved_registers' attribute in
GCC/LLVM with a provision for backward compatibility. It allows
compilers generate more efficient BPF code assuming the verifier or
JITs will inline or partially inline a helper/kfunc with such
attribute. bpf_cast_to_kern_ctx, bpf_rdonly_cast,
bpf_get_smp_processor_id are the first set of such helpers.

- Harden and extend ELF build ID parsing logic.

When called from sleepable context the relevants parts of ELF file
will be read to find and fetch .note.gnu.build-id information. Also
harden the logic to avoid TOCTOU, overflow, out-of-bounds problems.

- Improvements and fixes for sched-ext:
- Allow passing BPF iterators as kfunc arguments
- Make the pointer returned from iter_next method trusted
- Fix x86 JIT convergence issue due to growing/shrinking conditional
jumps in variable length encoding

- BPF_LSM related:
- Introduce few VFS kfuncs and consolidate them in
fs/bpf_fs_kfuncs.c
- Enforce correct range of return values from certain LSM hooks
- Disallow attaching to other LSM hooks

- Prerequisite work for upcoming Qdisc in BPF:
- Allow kptrs in program provided structs
- Support for gen_epilogue in verifier_ops

- Important fixes:
- Fix uprobe multi pid filter check
- Fix bpf_strtol and bpf_strtoul helpers
- Track equal scalars history on per-instruction level
- Fix tailcall hierarchy on x86 and arm64
- Fix signed division overflow to prevent INT_MIN/-1 trap on x86
- Fix get kernel stack in BPF progs attached to tracepoint:syscall

- Selftests:
- Add uprobe bench/stress tool
- Generate file dependencies to drastically improve re-build time
- Match JIT-ed and BPF asm with __xlated/__jited keywords
- Convert older tests to test_progs framework
- Add support for RISC-V
- Few fixes when BPF programs are compiled with GCC-BPF backend
(support for GCC-BPF in BPF CI is ongoing in parallel)
- Add traffic monitor
- Enable cross compile and musl libc

Merge branch 'local-vmtest-enhancement-and-rv64-enabled'

Pu Lehui says:

====================
Local vmtest enhancement and RV64 enabled

Patch 1-3 fix some problem about bpf selftests. Patch 4 add local rootfs
image support for vmtest. Patch 5 enable cross-platform testing for
vmtest. Patch 6-10 enable vmtest on RV64.

We can now perform cross platform testing for riscv64 bpf using the
following command:

PLATFORM=riscv64 CROSS_COMPILE=riscv64-linux-gnu- \
tools/testing/selftests/bpf/vmtest.sh \
-l <path of local rootfs image> -- \
./test_progs -d \
\"$(cat tools/testing/selftests/bpf/DENYLIST.riscv64 \
| cut -d'#' -f1 \
| sed -e 's/^[[:space:]]*//' \
-e 's/[[:space:]]*$//' \
| tr -s '\n' ',' \
)\"

For better regression, we rely on commit [0]. And since the work of riscv
ftrace to remove stop_machine atomic replacement is in progress, we also
need to revert commit [1] [2].

The test platform is x86_64 architecture, and the versions of relevant
components are as follows:
QEMU: 8.2.0
CLANG: 17.0.6 (align to BPF CI)
ROOTFS: ubuntu noble (generated by [3])
