CHECK 1OTHER 4

A maintenance release with a Go 1.26.8 toolchain update and correctness fixes in device scheduling, Windows kube-proxy, kubeadm configuration persistence, and DRA allocation. The recorded device scheduling fix changes how an unset `spec.deviceSelector` is handled.

  • breakingDeviceTaintRule device selector matching

    Applies if you use DeviceTaintRule without setting spec.deviceSelector.

    A DeviceTaintRule without spec.deviceSelector now matches no devices, instead of matching every device cluster-wide and making DRA devices unschedulable for NoSchedule or NoExecute taints. An explicit empty selector, deviceSelector: {}, targets all devices.

fixes (3)

  • - Fixed a panic in the Windows kube-proxy (winkernel) that could terminate kube-proxy when an HNS load balancer without port mappings was enumerated. ([#141681](https://github.com/kubernetes/kubernetes/pull/141681), [@prince-melvin](https://github.com/prince-melvin)) [SIG Network and Windows]
  • - Kube-scheduler: a ResourceClaim whose device request counts add up past the int range no longer crashes the scheduler or skips the firstAvailable fallback in the DRA allocator. A request over the per-claim device limit is rejected with an error naming it, and an oversized firstAvailable alternative falls through to a smaller one. ([#141922](https://github.com/kubernetes/kubernetes/pull/141922), [@thc1006](https://github.com/thc1006)) [SIG Node]
  • - Kubeadm: no longer persists a node-specific systemd-resolved resolvConf path in the cluster-wide kubelet-config ConfigMap during init. ([#141627](https://github.com/kubernetes/kubernetes/pull/141627), [@HirazawaUi](https://github.com/HirazawaUi)) [SIG Cluster Lifecycle]
