Move dump package from apimachinery to k8s.io/utils 
Replace all imports of k8s.io/apimachinery/pkg/util/dump with
k8s.io/utils/dump across the repo. The apimachinery dump package
now contains deprecated wrapper functions that delegate to
k8s.io/utils/dump for backwards compatibility.

fix flake on ipaddress allocator integration test 
The test need to consider the time for the Delete operation to populate
the ipallocator informer, otherwise, it can happen the allocator fails
with a range full failing the test.

fake client-go: un-deprecate NewSimpleClientset
 2026-02-10 01:33:59 +05:30
Patrick Ohly
e80da21868 fake client-go: un-deprecate NewSimpleClientset 
NewSimpleClientset was marked as deprecated when NewClientset was
introduced. This has caused some confusion:
- Not all packages have NewClientset (https://github.com/kubernetes/kubernetes/issues/135980).
- Tests that work with NewSimpleClientset fail when
  switched to NewClientset (https://github.com/kubernetes/kubernetes/issues/136327)
  because of missing CRD support (https://github.com/kubernetes/kubernetes/issues/126850).

It doesn't seem burdensome to keep NewSimpleClientset around forever. Some unit
tests may even prefer to use it when they don't need server-side apply (less
overhead). Therefore there is no need to deprecate it.

This avoids churn in the eco system because contributors no longer create PRs
"because the linter complains about the usage of a deprecated function".

5a2578ce09 kubelet: promote the CustomCPUCFSQuotaPeriod to GA 
Promote the CustomCPUCFSQuotaPeriod gate to GA, turning it enabled by
default. Short history of this feature so far:

As far as git and github history allows to reconstruct, this
feature was introduced without KEP/design doc process (kubernetes 1.12).
It was a double-opt-in feature: users set to first enable a FG to make
the kubelet honor a setting, then change a specific tunable to change
the behavior This is more like a “safeguard” FG
(Other noteworthy examples: `UnauthenticatedHTTP2DOSMitigation` or
`DisableCPUQuotaWithExclusiveCPUs`) rather than a KEP-driven feature gate

Major past events:
- introduced in: https://github.com/kubernetes/kubernetes/pull/63437
- Discussion about adding a FG: https://github.com/kubernetes/kubernetes/pull/63437#issuecomment-387828654
- The change was initially accepted as straightforward, but it was
  later discovered systemd had gaps, and the change was downgraded
  as experimental: https://github.com/kubernetes/kubernetes/pull/63437#issuecomment-391740566
- FG re-introduced because systemd acknowledged and fixed the gap,
  but the systemd rollout would take quite some time:
  https://github.com/kubernetes/kubernetes/pull/63437#issuecomment-407950436

There's a  gap, still relevant in 2026: missing e2e tests to move past alpha:
https://github.com/kubernetes/kubernetes/pull/63437#issuecomment-417674790

Other noteworthy work related to this feature:
- https://github.com/kubernetes/kubernetes/pull/94687
- https://github.com/kubernetes/kubernetes/pull/111520
- https://github.com/kubernetes/kubernetes/pull/129726
- https://github.com/kubernetes/kubernetes/pull/133845

Fix and modernize the related unit tests.

440cfca4ef refactor(kube-proxy): remove redundant empty endpoints check in topologyModeFromHints 
The len(endpoints) == 0 check is now redundant since the hasReadyEndpoints
check handles this case when the slice is empty, the loop executes zero
times, hasReadyEndpoints stays false, and returns "" via the same path.

18f56fa7c7 fix(kube-proxy): skip topology hints logging when no ready endpoints exist 
When all endpoints are non-ready (ready=false, serving=false, terminating=false),
the topologyModeFromHints function was incorrectly logging "Ignoring same-zone
topology hints for service since no hints were provided for zone" because the
boolean flags remained at their initial values after the loop skipped all
non-ready endpoints.

This fix adds tracking for whether any ready endpoints were processed and
returns early if none exist, avoiding misleading log messages.

Also adds a test case covering this scenario.

317c96a062 Fix data race in PopulateRefs by copying Items and AdditionalProperties 
The populateRefs function was modifying result.Items.Schema and
result.AdditionalProperties.Schema directly. Since result is a shallow
copy of the input schema, these pointer fields still reference the
original shared structures, causing a data race when multiple goroutines
