bpf 2023-01-16

We've added 6 non-merge commits during the last 8 day(s) which contain
a total of 6 files changed, 22 insertions(+), 24 deletions(-).

The main changes are:

1) Mitigate a Spectre v4 leak in unprivileged BPF from speculative
   pointer-as-scalar type confusion, from Luis Gerhorst.

2) Fix a splat when pid 1 attaches a BPF program that attempts to
   send killing signal to itself, from Hao Sun.

3) Fix BPF program ID information in BPF_AUDIT_UNLOAD as well as
   PERF_BPF_EVENT_PROG_UNLOAD events, from Paul Moore.

4) Fix BPF verifier warning triggered from invalid kfunc call in
   backtrack_insn, also from Hao Sun.

5) Fix potential deadlock in htab_lock_bucket from same bucket index
   but different map_locked index, from Tonghao Zhang.

* tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf:
  bpf: Fix pointer-leak due to insufficient speculative store bypass mitigation
