selftests/bpf: test_progs: fix client/server race in tcp_rtt
This is the same problem I found earlier in test_sockopt_inherit: there is a race between server thread doing accept() and client thread doing connect(). Let's explicitly synchronize them via pthread conditional variable. v2: * don't exit from server_thread without signaling condvar, fixes possible issue where main() would wait forever (Andrii Nakryiko) Fixes: b55873984dab ("selftests/bpf: test BPF_SOCK_OPS_RTT_CB") Signed-off-by: Stanislav Fomichev <sdf@google.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
