### Failing Test

- Kubelet: the HostPort implementation in dockershim was not taking into consideration the HostIP field, causing that the same HostPort can not be used with different IP addresses.

* Back port - Openstack provider allowing more than one service port for lbaas v2 ([#32001](https://github.com/kubernetes/kubernetes/pull/32001), [@dagnello](https://github.com/dagnello))
* 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))
