Selftests here check not only that connect()/accept() for TCP-AO/TCP-MD5/non-signed-TCP combinations do/don't establish connections, but also counters: those are per-AO-key, per-socket and per-netns. The counters are checked on the server's side, as the server listener has TCP-AO/TCP-MD5/no keys for different peers. All tests run in the same namespaces with the same veth pair, created in test_init(). After close() in both client and server, the sides go through the regular FIN/ACK + FIN/ACK sequence, which goes in the background. If the selftest has already started a new testing scenario, read per-netns counters - it may fail in the end iff it doesn't expect the TCPAOGood per-netns counters go up during the test. Let's just kill both TCP-AO sides - that will avoid any asynchronous background TCP-AO segments going to either sides.
