Here the differences I spot on a high level:
4. OVS-DPDK - ping vhost-user ports
- testpmd.log - not much difference
- ovsdb-server.log
ovsdb-server is killed (sig 15) in the bad case 7 seconds after starting
that kill is after the test log ends, so it could be cleanup
- ovs-vswitchd.log
dpdk|ERR|TELEMETRY: Socket write base info to client failed (likely red
herring)
in addition to all-same messages like the good case, the bad case shows
dpdk|ERR|remove_xdp_program(): bpf_xdp_query_id failed
dpdk|ERR|eth_dev_close(): Error while removing XDP program.
- system-dpdk-testsuite.log
differs at the end, good case seems to enter cleanup while bad case does
lots of things
bad case has more content as it reports detailed steps
can't cleanup testpmd (pid already gone)
16. OVS-DPDK - MTU increase vport port
17. OVS-DPDK - MTU decrease vport port (same)
20. OVS-DPDK - MTU upper bound vport port (same)
21. OVS-DPDK - MTU lower bound vport port (same)
- testpmd.log
good case sees ports going down and stopping
- ovsdb-server.log
ovsdb-server is killed (sig 15) in the bad case a few seconds after
starting
that kill is after the test log ends, so it could be cleanup
- ovs-vswitchd.log
dpdk|ERR|TELEMETRY: Socket write base info to client failed (likely red
herring)
- system-dpdk-testsuite.log
differs at the end, good case seems to enter cleanup while bad case does
lots of things
bad case has more content as it reports detailed steps
can't cleanup testpmd (pid already gone)
So on case 4 it could be the xdp error which is new.
On the other cases only the telemetry is odd, but that seemed (see above) like
a false positive.
Yet there are chances a component I didn't see yet tests on no ERR messages.
Worth a rebuild with this reverted?
