DefaultDeny namespace annotation. Note: this will enforce policy for *all* pods in the namespace: ``` kubectl annotate namespace default "net.beta.kubernetes.io/network-policy={\"ingress\":{\"isolation\":\"DefaultDeny\"}}" ``` With NetworkPolicy enabled, traffic will be limited to just port 9000. For more precise policy, set `networkPolicy.allowExternal=true`. This will only allow pods with the generated client label to connect to MinIO. This label will be displayed in the output of a successful install....

- Fixed a bug where improper storage and comparison of endpoints led to excessive API traffic from the endpoints controller ([#94935](https://github.com/kubernetes/kubernetes/pull/94935), [@damemi](https://github.com/damemi)) [SIG Apps, Network and Testing]

- Kube-proxy: fix a bug on UDP NodePort Services where stale conntrack entries may blackhole the traffic directed to the NodePort. ([#98305](https://github.com/kubernetes/kubernetes/pull/98305), [@aojea](https://github.com/aojea)) [SIG Network]

### Bug or Regression

- Fixed issue in `Winkernel` Proxier - Unexpected active TCP connection drops while horizontally scaling the endpoints for a LoadBalancer Service with Internal Traffic Policy: `Local` ([#113742](https://github.com/kubernetes/kubernetes/pull/113742), [@princepereira](https://github.com/princepereira))

### CVE-2022-3172: Aggregated API server can cause clients to be redirected (SSRF)

A security issue was discovered in kube-apiserver that could allow an attacker controlled aggregated API server to redirect client traffic to any URL.  This could lead to the client performing unexpected actions as well as leaking the client's credentials to third parties. 

*   Graduate kube-proxy IPVS mode to beta. ([#56623](https://github.com/kubernetes/kubernetes/pull/56623), [@m1093782566](https://github.com/m1093782566))

#### **Kube-Proxy**

*   Added iptables rules to allow Pod traffic even when default iptables policy is to reject. ([#52569](https://github.com/kubernetes/kubernetes/pull/52569),[ @tmjd](https://github.com/tmjd))

- Fix race condition in kube-proxy initialization that could blackhole UDP traffic to service VIP. ([#126688](https://github.com/kubernetes/kubernetes/pull/126688), [@wedaly](https://github.com/wedaly)) [SIG Network]
