The resource claim controller is completely agnostic to the claim spec. It
doesn't care about classes or devices, therefore it needs no changes in 1.31
besides the v1alpha2 -> v1alpha3 renaming from a previous commit.
As agreed in https://github.com/kubernetes/enhancements/pull/4709, immediate
allocation is one of those features which can be removed because it makes no
sense for structured parameters and the justification for classic DRA is weak.
This is in preparation for revamping the resource.k8s.io completely. Because
there will be no support for transitioning from v1alpha2 to v1alpha3, the
roundtrip test data for that API in 1.29 and 1.30 gets removed.
Repeating the version in the import name of the API packages is not really
required. It was done for a while to support simpler grepping for usage of
alpha APIs, but there are better ways for that now. So during this transition,
"resourceapi" gets used instead of "resourcev1alpha3" and the version gets
dropped from informer and lister imports. The advantage is that the next bump
to v1beta1 will affect fewer source code lines.
Only source code where the version really matters (like API registration)
retains the versioned import.
When a resource gets deleted during migration, the SVM SSA patch
calls are interpreted as a logical create request. Since the object
from storage is nil, the merged result is just a type meta object,
which lacks a name in the body. This fails when the API server
checks that the name from the request URL and the body are the same.
Note that a create request is something that SVM controller should
never do.
Once the UID is set on the patch, the API server will fail the
request at a slightly earlier point with an "uid mismatch" conflict
error, which the SVM controller can handle gracefully.
Setting UID by itself is not sufficient. When a resource gets
deleted and recreated, if RV is not set but UID is set, we would get
an immutable field validation error for attempting to update the
UID. To address this, we set the resource version on the SSA patch
as well. This will cause that update request to also fail with a
conflict error.
Added the create verb on all resources for SVM controller RBAC as
otherwise the API server will reject the request before it fails
with a conflict error.
The change addresses a host of other issues with the SVM controller:
1. Include failure message in SVM resource
2. Do not block forever on unsynced GC monitor
3. Do not immediately fail on GC monitor being missing, allow for
a grace period since discovery may be out of sync
4. Set higher QPS and burst to handle large migrations
Test changes:
1. Clean up CRD webhook convertor logs
2. Allow SVM tests to be run multiple times to make finding flakes easier
3. Create and delete CRs during CRD test to force out any flakes
4. Add a stress test with multiple parallel migrations
5. Enable RBAC on KAS
6. Run KCM directly to exercise wiring and RBAC
7. Better logs during CRD migration
8. Scan audit logs to confirm SVM controller never creates

The new k8s.io/utils/ptr package provides generic wrapper functions,
which can be used instead of type-specific pointer wrapper functions.
This replaces the latter with the former, and migrates other uses of
the deprecated pointer package to ptr in affected files.

When Pod state changes rapidly, endpoints controller may use outdated
informer cache to sync Service. If the outdated endpoints appear to be
expected by the controller, it skips updating it.
The commit fixes it by checking if endpoints informer cache is outdated
when processing a service. If the endpoints is stale, it returns an
error and retries later.
