- The scheduling queue didn't notice any extenders' failures, it could miss some cluster events,
  and it could end up Pods rejected by Extenders stuck in unschedulable pod pool in 5min in the worst-case scenario.
  Now, the scheduling queue notices extenders' failures and requeue Pods rejected by Extenders appropriately. ([#122044](https://github.com/kubernetes/kubernetes/pull/122044), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling]

		c.Fatalf("policy add error: %v", err)
	}

	info, err := s.adm.InfoCannedPolicy(ctx, "readwrite")
	if err != nil {
		c.Fatalf("policy info err: %v", err)
	}

	// Check that policy with comma is rejected.
	err = s.adm.AddCannedPolicy(ctx, "invalid,policy", policyBytes)
	if err == nil {
		c.Fatalf("invalid policy created successfully")
	}

	infoStr := string(info)

but the unsigned 64-bit integer with the same bit pattern.
The distinction rarely matters but
to avoid ambiguity, division or right shift where the right operand's
high bit is set is rejected.

### Other notable changes

* Connections from Pods to Services with 0 endpoints will now ICMP reject immediately, rather than blackhole and timeout. ([#72534](https://github.com/kubernetes/kubernetes/pull/72534), [@thockin](https://github.com/thockin))

				t.Errorf("file %d: bad size: copied=%d; want=%d", i, n, f.UncompressedSize64)
			}
		}
		r.Close()
	}
}

// Verify that this particular malformed zip file is rejected.
func TestIssue10956(t *testing.T) {
	data := []byte("PK\x06\x06PK\x06\a0000\x00\x00\x00\x00\x00\x00\x00\x00" +

- The `rejected` label in `apiserver_admission_webhook_admission_duration_seconds` metrics now properly indicates if the request was rejected. ([#81399](https://github.com/kubernetes/kubernetes/pull/81399), [@roycaihw](https://github.com/roycaihw))

        assertThrows(
                ProjectBuildingException.class,
                () -> buildPom("parent-pom-packaging/sub"),
                "Wrong packaging of parent POM was not rejected");
    }

    void testManagedPluginConfigurationAppliesToImplicitPluginsIntroducedByPackaging() throws Exception {

  * kube-apiserver learned the '--anonymous-auth' flag, which defaults to true. When enabled, requests to the secure port that are not rejected by other configured authentication methods are treated as anonymous requests, and given a username of 'system:anonymous' and a group of 'system:unauthenticated'.
  * Authenticated users are decorated with a 'system:authenticated' group.

* Fix Forward chain default reject policy for IPVS proxier ([#62007](https://github.com/kubernetes/kubernetes/pull/62007), [@m1093782566](https://github.com/m1093782566))
* fix nsenter GetFileType issue in containerized kubelet ([#62467](https://github.com/kubernetes/kubernetes/pull/62467), [@andyzhangx](https://github.com/andyzhangx))

- Fixed a regression that could incorrectly reject pods with `OutOfCpu` errors if they were rapidly scheduled after other pods were reported as complete in the API. The Kubelet now waits...
