[PATCH bpf-next v5 0/2] Fix bpf_strnstr len error

[Rong Tao]

From: Rong Tao <rongtao@cestc.cn>

Fix bpf_strnstr() wrong 'len' parameter, bpf_strnstr("open", "open", 4)
should return 0 instead of -ENOENT. And fix a more general case when s2
is a suffix of the first len characters of s1.

Rong Tao (2):
  bpf/helpers: bpf_strnstr: Exact match length
  selftests/bpf: Add tests for bpf_strnstr
