Date: Fri, 9 Sep 2022 12:30:50 -0700	[thread overview]
Message-ID: <20220909193053.577111-1-andrii@kernel.org> (raw)

Add a simple mass-verification and stats collection tool, veristat, to
selftests/bpf for use by everyone. See patch #3 for some more details.

Patch #1 fixes two BPF objects to be more usable with veristat.

Patch #2 fixes libbpf bug which also was discovered trying to mass-verify
a bunch of internal Meta BPF object files.

v1->v2:
  - fix obj leak (Kui-Feng);
  - fix Makefile deps (Daniel).

Andrii Nakryiko (3):
  selftests/bpf: fix test_verif_scale{1,3} SEC() annotations
  libbpf: fix crash if SEC("freplace") programs don't have
    attach_prog_fd set
  selftests/bpf: add veristat tool for mass-verifying BPF object files
