Hi all,
I get vswitchd crash (segfault) consistently with flow table 254
deletion and with traffic. This special table has internal flows/rules
(miss_rule, no_packet_in_rule etc) added during bridge creation and are
getting deleting with ovs-ofctl del-flows <br_name> "table=254". These
deleted stale rules are referred (xbridge->miss_rule and
xbridge->no_packet_in_rule) when there is no flow match and resulting in
segfault. I guess, these default flows shouldn't be deleted, but if they
are part of flow tables, can be deleted. so we should move them a place
where they never get deleted and always available.
Please suggest.
