Andrey Ignatov e50b0a6f08 selftests/bpf: Selftest for sys_bind hooks ... Add selftest to work with bpf_sock_addr context from `BPF_PROG_TYPE_CGROUP_SOCK_ADDR` programs. Try to bind(2) on IP:port and apply: * loads to make sure context can be read correctly, including narrow loads (byte, half) for IP and full-size loads (word) for all fields; * stores to those fields allowed by verifier. All combination from IPv4/IPv6 and TCP/UDP are tested. Both scenarios are tested: * valid programs can be loaded and attached; * invalid programs can be neither loaded nor attached. Test passes when expected data can be read from context in the BPF-program, and after the call to bind(2) socket is bound to IP:port pair that was written by BPF-program to the context. Example: # ./test_sock_addr Attached bind4 program. Test case #1 (IPv4/TCP): Requested: bind(192.168.1.254, 4040) .. Actual: bind(127.0.0.1, 4444) Test case #2 (IPv4/UDP): Requested: bind(192.168.1.254, 4040) .. Actual: bind(127.0.0.1, 4444) Attached bind6 program. Test case #3 (IPv6/TCP): Requested: bind(face:b00c:1234:5678::abcd, 6060) .. Actual: bind(::1, 6666) Test case #4 (IPv6/UDP): Requested: bind(face:b00c:1234:5678::abcd, 6060) .. Actual: bind(::1, 6666) ### SUCCESS 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 02:15:30 +02:00
