large LIST calls into multiple smaller chunks. A client can specify a limit to the number of results to return. If more results exist, a token is returned that allows the client to continue the previous list call repeatedly until all results are retrieved.  The resulting list is identical to a list call that does not perform chunking, thanks to capabilities provided by etcd3.  This allows the server to use less memory and CPU when very large lists are returned. This feature is gated as APIListChunking...

- Fixed bug that caused cAdvisor to incorrectly detect single-socket multi-NUMA topology. ([#99209](https://github.com/kubernetes/kubernetes/pull/99209), [@iwankgb](https://github.com/iwankgb)) [SIG Node]
- Fixes kubelet to retrieve number of sockets from cAdvisor MachineInfo, instead of assuming it to be equal to number of NUMA nodes. ([#99771](https://github.com/kubernetes/kubernetes/pull/99771), [@iwankgb](https://github.com/iwankgb)) [SIG Node]

Kubernetes supports node proxying, which allows clients of kube-apiserver to access endpoints of a Kubelet to establish connections to Pods, retrieve container logs, and more. While Kubernetes already validates the proxying address for Nodes, a bug in kube-apiserver made it possible to bypass this validation. Bypassing this validation could allow authenticated requests destined for Nodes to be...

### Feature

- Kubernetes is now built with Golang 1.16.9 (#105672, @cpanato) [SIG Cloud Provider, Instrumentation, Release and Testing]

### Failing Test

- Backport: e2e.test now uses the secure port to retrieve metrics data to ensure compatibility with 1.21 and 1.22 (for upgrade tests) (#104328, @pohly) [SIG API Machinery, Instrumentation, Storage and Testing]

### Bug or Regression

- Aggregate errors when putting vmss
