selftests/bpf: Use libbpf 1.0 API mode instead of RLIMIT_MEMLOCK We have switched to memcg-based memory accouting and thus the rlimit is not needed any more. LIBBPF_STRICT_AUTO_RLIMIT_MEMLOCK was introduced in libbpf for backward compatibility, so we can use it instead now. After this change, the header tools/testing/selftests/bpf/bpf_rlimit.h can be removed. This patch also removes the useless header sys/resource.h from many files in tools/testing/selftests/bpf/.

bpf: Adjust bpf_tcp_check_syncookie selftest to test dual-stack sockets The previous commit fixed support for dual-stack sockets in bpf_tcp_check_syncookie. This commit adjusts the selftest to verify the fixed functionality.

selftests/bpf: add test for bpf_tcp_gen_syncookie Modify the existing bpf_tcp_check_syncookie test to also generate a SYN cookie, pass the packet to the kernel, and verify that the two cookies are the same (and both valid). Since cloned SKBs are skipped during generic XDP, this test does not issue a SYN cookie when run in XDP mode. We therefore only check that a valid SYN cookie was issued at the TC hook. Additionally, verify that the MSS for that SYN cookie is within expected range.

selftests/bpf: add tests for bpf_tcp_check_syncookie and bpf_skc_lookup_tcp Add tests which verify that the new helpers work for both IPv4 and IPv6, by forcing SYN cookies to always on. Use a new network namespace to avoid clobbering the global SYN cookie settings. Signed-off-by: Lorenz Bauer <lmb@cloudflare.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
