Build Update for horms2/ovs
-------------------------------------

Build: #541
Status: Failed

Duration: 16 mins and 5 secs
Commit: efbf033 (topic/branch-2.14/roid/race-fix)
Author: Jianbo Liu
Message: ofproto-dpif-upcall: Fix race condition while purging

There is a race condidtion between purger and handler. Handler may
create new ukey and install it while executing 'ovs-appctl
revalidator/purge' command. However, before handler calls
transition_ukey() in handle_upcalls(), purger may get this ukey from
umap, then evict and delete it. This will trigger ovs_abort in
transition_ukey() for handler because it is trying to set state to
EVICTED or OPERATIONAL, but ukey is already in DELETED state.
To fix this issue, purger must not delete ukey in VISIBLE state.

Fixes: 98bb4286970d ("tests: Add command to purge revalidators of flows.")
