[PATCH bpf-next 0/3] Remove libcap dependency from bpf selftests

[Martin KaFai Lau <kafai@fb.com>]

After upgrading to the newer libcap (>= 2.60),
the libcap commit aca076443591 ("Make cap_t operations thread safe.")
added a "__u8 mutex;" to the "struct _cap_struct".  It caused a few byte
shift that breaks the assumption made in the "struct libcap" definition
in test_verifier.c.

This set is to remove the libcap dependency from the bpf selftests.

Martin KaFai Lau (3):
  bpf: selftests: Add helpers to directly use the capget and capset
    syscall
  bpf: selftests: Remove libcap usage from test_verifier
  bpf: selftests: Remove libcap usage from test_progs
