Re: [PATCH net v3 2/3] selftest/bpf: Add test for AF_VSOCK connect() racing sockmap update

Racing signal-interrupted connect() and sockmap update may result in an unconnected (and missing vsock transport) socket in a sockmap.

Test spends 2 seconds attempting to reach WARN_ON_ONCE().

connect / state = SS_CONNECTED / sock_map_update_elem if signal_pending state = SS_UNCONNECTED

connect transport = NULL vsock_bpf_recvmsg WARN_ON_ONCE(!vsk->transport)

This is apparently causing some bpf self-test failure. (Timeout? the self-test failure output is not clear to me.)

Could you please have a look?

Thanks!
