*	tools/bpf: fix test_sock and test_sock_addr.sh failure	Yonghong Song	2018-04-19
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The bpf selftests test_sock and test_sock_addr.sh failed in my test machine. The failure looks like: $ ./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) .. [FAIL] Test case: sock_create load w/ expected_attach_type .. [FAIL] Test case: attach type mismatch bind4 vs bind6 .. [FAIL] ... Summary: 4 PASSED, 12 FAILED $ ./test_sock_addr.sh Wait for testing IPv4/IPv6 to become available ..... ERROR: Timeout waiting for test IP to become available. In test_sock, bpf program loads failed due to hitting memlock limits. In test_sock_addr.sh, my test machine is a ipv6 only test box and using "ping" without specifying address family for an ipv6 address does not work. This patch fixed the issue by including header bpf_rlimit.h in test_sock.c and test_sock_addr.c, and specifying address family for ping command.

*	selftests/bpf: Selftest for sys_bind post-hooks.	Andrey Ignatov	2018-03-31
	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>
