e2e test validates the following 3 endpoints
- patchCoreV1NamespacedResourceQuotaStatus
- readCoreV1NamespacedResourceQuotaStatus
- replaceCoreV1ResourceQuotaForAllNamespacesStatus
This addresses a problem caused by
https://github.com/kubernetes/kubernetes/pull/112043: because the AfterEach
which invokes AllNodesReady always runs, including tests that skipped early,
those tests ran into a nil pointer access. This increased the size of log
files. The tests still worked.
Adds two tests for the enforcement of the ReadWriteOncePod
PersistentVolume access mode.
1. Tests that when two Pods are scheduled that reference the same
ReadWriteOncePod PVC, the latter-scheduled Pod will be marked
unschedulable because the PVC is in-use.
2. Tests that when two Pods are scheduled on the same node (setting
Pod.Spec.NodeName to bypass scheduling for the second Pod), the
latter Pod will fail to start because the PVC is already mounted on
the Node.
Included are changes to update the hostpath CSI driver to accept new CSI
access modes. Its sidecar containers are already at supported versions
for ReadWriteOncePod and don't need updating. The GCP PD CSI driver does
not yet support the new CSI access modes, but its sidecar containers are
at supported versions and so the feature will work.
To support ReadWriteOncePod, the following CSI sidecars must be updated
to these versions or greater:
- csi-provisioner:v3.0.0+
- csi-attacher:v3.3.0+
- csi-resizer:v1.3.0+

The reason for the issue is that the metrics were bumped before the
final job status update. In case the update failed the path was
repeated by the next syncJob leading to double-counting of the metrics.
The solution is to delay recording metrics and broadcasting events
after the job status update succeeds.
This change updates the API server code to load the encryption
config once at start up instead of multiple times. Previously the
code would set up the storage transformers and the etcd healthz
checks in separate parse steps. This is problematic for KMS v2 key
ID based staleness checks which need to be able to assert that the
API server has a single view into the KMS plugin's current key ID.

The change made in https://github.com/kubernetes/kubernetes/pull/112644
resulted in an update to the rejection message. In the memory manager
node e2e test, we still checked against the old expected error message
giving the impression that the pod succeeded to run even though it failed
as expected mainly because the check wasn't performed correctly.
In this patch, we update to the correct rejection message to make sure
that the memory manager is no longer failing.
NOTE: This test is supposed to run on multi NUMA systems and if the
underlying node does not have multi NUMA nodes, the test is skipped
which is what happens in upstream test infrastructure as it is mainly
composed of single NUMA nodes. Because of this, this test failure
wasn't evident via testgrid.
