* Fix a bug in kubelet hostport logic which flushes KUBE-MARK-MASQ iptables chain ([#32413](https://github.com/kubernetes/kubernetes/pull/32413), [@freehan](https://github.com/freehan))

- Ensure the `KUBE-MARK-DROP` chain in kube-proxy IPVS mode. The chain is ensured for both IPv4 and IPv6 in dual-stack operation. ([#82214](https://github.com/kubernetes/kubernetes/pull/82214), [@uablrek](https://github.com/uablrek))

* Bump ip-masq-agent to v2.1.1 ([#67916](https://github.com/kubernetes/kubernetes/pull/67916), [@MrHohn](https://github.com/MrHohn))
    * - Update debian-iptables image for CVEs.
    * - Change chain name to IP-MASQ to be compatible with the
    * pre-injected masquerade rules.

- The kubelet now creates an iptables chain named `KUBE-IPTABLES-HINT` in
  the `mangle` table. Containerized components that need to modify iptables
  rules in the host network namespace can use the existence of this chain
  to more-reliably determine whether the system is using iptables-legacy or
