Andrey Ignatov 976b4f3a46 selftests/bpf: Test [::] -> [::1] rewrite in sys_sendmsg in test_sock_addr ... Test that sys_sendmsg BPF hook doesn't break sys_sendmsg behaviour to rewrite destination IPv6 = [::] with [::1] (BSD'ism). Two test cases are added: 1) User passes dst IPv6 = [::] and BPF_CGROUP_UDP6_SENDMSG program doesn't touch it. 2) User passes dst IPv6 != [::], but BPF_CGROUP_UDP6_SENDMSG program rewrites it with [::]. In both cases [::1] is used by sys_sendmsg code eventually and datagram is sent successfully for unconnected UDP socket. Example of relevant output: Test case: sendmsg6: set dst IP = [::] (BSD'ism) .. [PASS] Test case: sendmsg6: preserve dst IP = [::] (BSD'ism) ..
