  Merge branch 'add-the-missing-bpf_link_type-invocation-for-sockmap' (2024-10-24 10:17:13 -0700)

----------------------------------------------------------------
BPF fixes:

- Fix an out-of-bounds read in bpf_link_show_fdinfo for BPF
  sockmap link file descriptors (Hou Tao)

- Fix BPF arm64 JIT's address emission with tag-based KASAN
  enabled reserving not enough size (Peter Collingbourne)

- Fix BPF verifier do_misc_fixups patching for inlining of the
  bpf_get_branch_snapshot BPF helper (Andrii Nakryiko)

- Fix a BPF verifier bug and reject BPF program write attempts
  into read-only marked BPF maps (Daniel Borkmann)

- Fix perf_event_detach_bpf_prog error handling by removing an
  invalid check which would skip BPF program release (Jiri Olsa)

- Fix memory leak when parsing mount options for the BPF
  filesystem (Hou Tao)
