Hello,
When I use ovs-ofctl on OVS 2.10.1, it failed occasionally by error:
ovs-ofctl: br0: failed to connect to socket (Broken pipe)
This error is possible to be reproduced with:
# while :; do /opt/nec/pf/ds/bin/ovs-ofctl --timeout=5 dump-flows br0 >
/tmp/log || break; done; cat /tmp/log
ovs-ofctl: br0: failed to connect to socket (Broken pipe)
Also I tried with OVS 2.4.1 and could not reproduce this error.
I think that recently rconn.c was modified on commit
476d2551abd2871696a64203f78d658ac2d7f32c
and the connection for ofctl was changed it begins on state S_CONNECTING
instead of S_ACTIVE.
So timeout_CONNECTING will be applied for ofctl connection, however
timeout_CONNECTING is 1
and this is too short (e.g. if transition time of CONNCTING was 12:00:00.999,
it will be timed out
after 1ms). I think that this is cause of occasionally disconnection of ofctl.
Thanks,
