Both of these are in 4.5 where we recently merged https://github.com/openshift/cluster-version-operator/pull/446 which is relevant to leader election, this is probably not a 4.6 blocker but we'll evaluate deeper tomorrow, leaving target release unassigned for now.
Looks like we need an upstream client-go fix backported. I'll try to figure out what our process is for that...
I've filed an upstream PR requesting a backport to 1.17.
This is 4.5 specific but the bot will revert my changes if i set target release to 4.5 directly, so setting it 4.7 now to get off the blocker list.
4.6+ use 1.19 clients which have this patched, so setting this modified to unblock a new-in-4.5 patch.
I'm trying to verify it on 4.7.0-0.nightly-2020-10-24-155529, but fresh installation on Azure faces Bug1891702, and GCP OVN cluster upgrade faces Bug1891716. I'll verify it once those bugs get fixed.
I'm verifying it on 4.7.0-0.nightly-2020-11-18-203317. Steps of verification are as below: 1. Fresh install an Azure cluster -- passed 2. Set up an OVN cluster on GCP with 4.6.5, and then do an upgrade to 4.7.0-0.nightly-2020-11-18-203317 - passed There's no panic found in CVO, hence moving it to verified state.
