* selftests/bpf: fix race in test_tcp_rtt testPetar Penkov2019-08-171-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | | There is a race in this test between receiving the ACK for the single-byte packet sent in the test, and reading the values from the map. This patch fixes this by having the client wait until there are no more unacknowledged packets. Before: for i in {1..1000}; do ../net/in_netns.sh ./test_tcp_rtt; \ done | grep -c PASSED < trimmed error messages > 993 After: for i in {1..10000}; do ../net/in_netns.sh ./test_tcp_rtt; \ done | grep -c PASSED 10000 Fixes: b55873984dab ("selftests/bpf: test BPF_SOCK_OPS_RTT_CB") Signed-off-by: Petar Penkov <ppenkov@google.com> Reviewed-by: Stanislav Fomichev <sdf@google.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>

Make sure the callback is invoked for syn-ack and data packet.
