Subject: [PATCH v3 bpf-next 7/9] selftests/bpf: Selftest for sys_connect hooks
From: Andrey Ignatov <rdna@...com>
Add selftest for BPF_CGROUP_INET4_CONNECT and BPF_CGROUP_INET6_CONNECT
attach types.
Try to connect(2) to specified IP:port and test that:
* remote IP:port pair is overridden;
* local end of connection is bound to specified IP.
All combinations of IPv4/IPv6 and TCP/UDP are tested.
Example:
# tcpdump -pn -i lo -w connect.pcap 2>/dev/null &
[1] 478
# strace -qqf -e connect -o connect.trace ./test_sock_addr.sh
