## Detailed Bug Fixes And Changes

### API Machinery

- client-go: `PortForwarder.GetPorts()` now contain correct local port if no local port was initially specified when setting up the port forwarder ([#73676](https://github.com/kubernetes/kubernetes/pull/73676), [@martin-helmich](https://github.com/martin-helmich))

		writeErrorResponseJSON(ctx, w, errorCodes.ToAPIErrWithErr(ErrAdminConfigBadJSON, err), r.URL)
		return
	}
	sameTarget, _ := isLocalHost(target.URL().Hostname(), target.URL().Port(), globalMinioPort)
	if sameTarget && bucket == target.TargetBucket {
		writeErrorResponseJSON(ctx, w, errorCodes.ToAPIErr(ErrBucketRemoteIdenticalToSource), r.URL)
		return
	}

	target.SourceBucket = bucket

      pushRequestLater(promisedStreamId, requestHeaders)
    }

    override fun alternateService(
      streamId: Int,
      origin: String,
      protocol: ByteString,
      host: String,
      port: Int,
      maxAge: Long,
    ) {
      // TODO: register alternate service.
    }
  }

  /** Even, positive numbered streams are pushed streams in HTTP/2. */

* Allow no ports when exposing headless service ([#32811](https://github.com/kubernetes/kubernetes/pull/32811), [@fraenkel](https://github.com/fraenkel))
* Wait for the port to be ready before starting ([#38260](https://github.com/kubernetes/kubernetes/pull/38260), [@fraenkel](https://github.com/fraenkel))

* Restored cAdvisor prometheus metrics to the main port -- a regression that existed in v1.7.0-v1.7.2 ([#49079](https://github.com/kubernetes/kubernetes/pull/49079), [@smarterclayton](https://github.com/smarterclayton))
    * cAdvisor metrics can now be scraped from `/metrics/cadvisor` on the kubelet ports.

- Fixed a bug where `kubectl describe` incorrectly displayed NetworkPolicy port ranges
  (showing only the starting port). ([#123316](https://github.com/kubernetes/kubernetes/pull/123316), [@jcaamano](https://github.com/jcaamano))
- Fixed a bug where hard evictions due to resource pressure allowed pods

 
## Changes by Kind

### Deprecation

- Controller-manager: the following flags have no effect and would be removed in v1.24:
  - `--port`
  - `--address`
  The insecure port flags `--port` may only be set to 0 now.
  
  In addtion, please be careful that:
