Added test for snoop command to check for the initial handshake messages when a bridge connects to a controller via 'unix' connection method.
Signed-off-by: Ashish Varma <ashishvarma....@gmail.com> --- v1-v2: Removed the sleep and added OVS_WAIT_UNTIL. Added comment on why we are adding an exception for the 'connection failed' WARN log message. Added '-vsyslog:off'. Minor change for pid file name change. --- tests/ovs-ofctl.at | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) diff --git a/tests/ovs-ofctl.at b/tests/ovs-ofctl.at index 06597d7..a1eecad 100644 --- a/tests/ovs-ofctl.at +++ b/tests/ovs-ofctl.at @@ -3184,3 +3184,31 @@ AT_CHECK([grep -q "ct_dpif|DBG|.*ct_flush: zone 123" ovs-vswitchd.log]) OVS_VSWITCHD_STOP AT_CLEANUP + + +AT_SETUP([ovs-ofctl snoop-unix-connection]) +OVS_VSWITCHD_START + +dnl setup controller for br0 before starting the controller +AT_CHECK([ovs-vsctl -vsyslog:off set-controller br0 unix:testcontroller]) + +dnl then start listening on the '.snoop' connection +AT_CHECK([ovs-ofctl -vsyslog:off --detach --pidfile=ovs-ofctl-snoop.pid snoop br0 1> snoopbr0.txt 2>&1]) +on_exit 'kill `cat ovs-ofctl-snoop.pid`' +on_exit 'unlink snoopbr0.txt' + +dnl finally start the controller +AT_CHECK([ovs-testcontroller -vsyslog:off --detach --pidfile punix:testcontroller], [0], [ignore]) +on_exit 'kill `cat ovs-testcontroller.pid`' +OVS_WAIT_UNTIL([test -e testcontroller]) + +dnl check for some of the initial handshake messages +OVS_WAIT_UNTIL([egrep "OFPT_FEATURES_REQUEST" snoopbr0.txt 1> /dev/null 2>&1]) +OVS_WAIT_UNTIL([egrep "OFPT_FEATURES_REPLY" snoopbr0.txt 1> /dev/null 2>&1]) +OVS_WAIT_UNTIL([egrep "OFPT_SET_CONFIG" snoopbr0.txt 1> /dev/null 2>&1]) + +dnl need to suppress the 'connection failed' WARN message in ovs-vswitchd +dnl because we need ovs-vswitchd to have the controller config before starting +dnl the controller to 'snoop' the OpenFlow messages from beginning +OVS_VSWITCHD_STOP(["/connection failed (No such file or directory)/d"]) +AT_CLEANUP -- 2.7.4 _______________________________________________ dev mailing list d...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-dev
