### Feature

- A client-go metric, rest_client_exec_plugin_call_total, has been added to track total calls to client-go credential plugins. ([#98892](https://github.com/kubernetes/kubernetes/pull/98892), [@ankeesler](https://github.com/ankeesler)) [SIG API Machinery, Auth, Cluster Lifecycle and Instrumentation]

- Removed the last remaining in-tree gcp cloud provider and credential provider.
  Please use the external cloud provider and credential provider from https://github.com/kubernetes/cloud-provider-gcp

	now := UTCNow()

	req = signer.StreamingUnsignedV4(req, "", 8, now)

	maliciousHeaders := http.Header{
		"Authorization":                []string{fmt.Sprintf("AWS4-HMAC-SHA256 Credential=%s/%s/us-east-1/s3/aws4_request, SignedHeaders=invalidheader, Signature=deadbeefdeadbeefdeadbeeddeadbeeddeadbeefdeadbeefdeadbeefdeadbeef", s.accessKey, now.Format(yyyymmdd))},

* vendor: update github.com/coreos/go-oidc client package ([#31564](https://github.com/kubernetes/kubernetes/pull/31564), [@ericchiang](https://github.com/ericchiang))
* Fixed an issue that caused a credential error when deploying federation control plane onto a GKE cluster. ([#31747](https://github.com/kubernetes/kubernetes/pull/31747), [@madhusudancs](https://github.com/madhusudancs))

* Match GroupVersionKind against specific version ([#34010](https://github.com/kubernetes/kubernetes/pull/34010), [@soltysh](https://github.com/soltysh))

Então nós podemos utilizar o `secrets.compare_digest()` para garantir que o `credentials.username` é `"stanleyjobson"`, e que o `credentials.password` é `"swordfish"`.

{* ../../docs_src/security/tutorial007_an_py39.py hl[1,12:24] *}

Isso seria parecido com:

```Python
if not (credentials.username == "stanleyjobson") or not (credentials.password == "swordfish"):
    # Return some error
    ...
```

- Fixed ambiguous behavior when bearer token (kubectl --token=..) and an exec credential plugin was configured in the same context - the bearer token now takes precedence.
