Linus Torvalds 3d5ad2d4ec 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.
