lib/buildid: Handle memfd_secret() files in build_id_parse() (2024-10-17 21:30:32 +0200)
----------------------------------------------------------------
BPF fixes:
- Fix BPF verifier to not affect subreg_def marks in its range
propagation, from Eduard Zingerman.
- Fix a truncation bug in the BPF verifier's handling of
coerce_reg_to_size_sx, from Dimitar Kanaliev.
- Fix the BPF verifier's delta propagation between linked
registers under 32-bit addition, from Daniel Borkmann.
- Fix a NULL pointer dereference in BPF devmap due to missing
rxq information, from Florian Kauer.
- Fix a memory leak in bpf_core_apply, from Jiri Olsa.
- Fix an UBSAN-reported array-index-out-of-bounds in BTF
parsing for arrays of nested structs, from Hou Tao.
- Fix build ID fetching where memory areas backing the file
were created with memfd_secret, from Andrii Nakryiko.
- Fix BPF task iterator tid filtering which was incorrectly
using pid instead of tid, from Jordan Rome.
- Several fixes for BPF sockmap and BPF sockhash redirection
in combination with vsocks, from Michal Luczaj.
- Fix riscv BPF JIT and make BPF_CMPXCHG fully ordered,
from Andrea Parri.
- Fix riscv BPF JIT under CONFIG_CFI_CLANG to prevent the
possibility of an infinite BPF tailcall, from Pu Lehui.
- Fix a build warning from resolve_btfids that bpf_lsm_key_free
cannot be resolved, from Thomas Weißschuh.
- Fix a bug in kfunc BTF caching for modules where the wrong
BTF object was returned, from Toke Høiland-Jørgensen.
- Fix a BPF selftest compilation error in cgroup-related tests
with musl libc, from Tony Ambardar.
- Several fixes to BPF link info dumps to fill missing fields,
from Tyrone Wu.
- Add BPF selftests for kfuncs from multiple modules, checking
that the correct kfuncs are called, from Simon Sundberg.
- Ensure that internal and user-facing bpf_redirect flags
don't overlap, also from Toke Høiland-Jørgensen.
- Switch to use kvzmalloc to allocate BPF verifier environment,
from Rik van Riel.
- Use raw_spinlock_t in BPF ringbuf to fix a sleep in atomic
splat under RT, from Wander Lairson Costa.
