bpf: Test BPF_PROG_TYPE_SK_REUSEPORT
This patch add tests for the new BPF_PROG_TYPE_SK_REUSEPORT. The tests cover: - IPv4/IPv6 + TCP/UDP - TCP syncookie - TCP fastopen - Cases when the bpf_sk_select_reuseport() returning errors - Cases when the bpf prog returns SK_DROP - Values from sk_reuseport_md - outer_map => reuseport_array The test depends on commit 3eee1f75f2b9 ("bpf: fix bpf_skb_load_bytes_relative pkt length check") Signed-off-by: Martin KaFai Lau <kafai@fb.com> Acked-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
