Andrey Ignatov 1d436885b2 selftests/bpf: Selftest for sys_bind post-hooks. ... Add selftest for attach types `BPF_CGROUP_INET4_POST_BIND` and `BPF_CGROUP_INET6_POST_BIND`. The main things tested are: * prog load behaves as expected (valid/invalid accesses in prog); * prog attach behaves as expected (load- vs attach-time attach types); * `BPF_CGROUP_INET_SOCK_CREATE` can be attached in a backward compatible way; * post-hooks return expected result and errno. Example: # ./test_sock Test case: bind4 load with invalid access: src_ip6 .. [PASS] Test case: bind4 load with invalid access: mark .. [PASS] Test case: bind6 load with invalid access: src_ip4 .. [PASS] Test case: sock_create load with invalid access: src_port .. [PASS] Test case: sock_create load w/o expected_attach_type (compat mode) .. [PASS] Test case: sock_create load w/ expected_attach_type .. [PASS] Test case: attach type mismatch bind4 vs bind6 .. [PASS] Test case: attach type mismatch bind6 vs bind4 .. [PASS] Test case: attach type mismatch default vs bind4 .. [PASS] Test case: attach type mismatch bind6 vs sock_create .. [PASS] Test case: bind4 reject all .. [PASS] Test case: bind6 reject all .. [PASS] Test case: bind6 deny specific IP & port .. [PASS] Test case: bind4 allow specific IP & port .. [PASS] Test case: bind4 allow all .. [PASS] Test case: bind6 allow all .. [PASS] Summary: 16 PASSED, 0 FAILED Signed-off-by: Andrey Ignatov <rdna@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>		2018-03-31 02:16:40 +02:00
