Subject: Re: [PATCH 5.10 373/575] selftests: bpf: Convert sk_lookup ctx access
 tests to PROG_TEST_RUN

Hi Greg.

We found a compile error when building tools/testing/selftests/bpf/ on 5.10.

tools/testing/selftests/bpf/prog_tests/sk_lookup.c:1092:15: error: 'struct bpf_sk_lookup' has no member named 'cookie'
  1092 |  if (CHECK(ctx.cookie == 0, "ctx.cookie", "no socket selected\n"))

It requires 7c32e8f8bc33 ("bpf: Add PROG_TEST_RUN support for sk_lookup programs") from upstream.

Maybe the left patches of this patchset are needed for 5.10 LTS?

Thanks.
