Cilium - v1.14.4

We are pleased to release Cilium v1.14.4. This release includes several network policy performance improvements, improvements and fixes for IPSec, and numerous bug fixes and architectural improvements.

Summary of Changes

Minor Changes:
* certmanager: solve CannotRegenerateKey (Backport PR #29030, Upstream PR #28787, @universam1)
* Cilium DNS proxy now uses the original pod's address as the source address towards the DNS servers. (Backport PR #29086, Upstream PR #28928, @jrajahalme)
* Cilium now properly deletes stale (deleted) nodes from the node_connectivity_status and node_connectivity_latency_seconds metrics, reducing metric cardinality. (Backport PR #28980, Upstream PR #28382, @derailed)
* Display interfaces used for IPsec decryption in cilium encrypt status. (Backport PR #28759, Upstream PR #28640, @pchaigno)
* helm: delete AWS iptables in all deployments aside from AWS CNI chaining environments (Backport PR #28870, Upstream PR #28697, @nebril)
* ipsec: New Prometheus metrics for XFRM configs (Backport PR #28759, Upstream PR #28400, @pchaigno)
* policy: Cilium will not process or enforce network policies with port ranges or Kubernetes network policies that use "EndPort". (Backport PR #29030, Upstream PR #28704, @nathanjsweet)
* policy: Fixed a bug that incorrectly omitted port-protocol policy rules that omitted the "protocol" field. An omitted "protocol" field now, correctly, is the same as using the "ANY" protocol. (Backport PR #28759, Upstream PR #28703, @nathanjsweet)
* v1.14: WG tunneling (#28917, @brb)

* bpf: Add TC_ACT_REDIRECT check for nodeport (Backport PR #29030, Upstream PR #28927, @sayboras)
* Don't bind a /64 address to cilium_host to avoid misrouting cross-node traffic (Backport PR #28759, Upstream PR #28633, @CallMeFoxie)
* envoy: fix lb backend endpoint calculation (Backport PR #28870, Upstream PR #27923, @mhofstetter)
* Fix CIDR labels computation (Backport PR #28870, Upstream PR #28788, @pippolo84)
* Fix concurrency issue when changing labels on pods started before Cilium setup their network. Cilium will now process pod labels modified while setting up the pod network. (Backport PR #28870, Upstream PR #28789, @aanm)
* Fix false positives of 'Key allocation attempt failed' in CRD mode (Backport PR #29064, Upstream PR #28810, @aanm)
* Fix incorrect logic used by the Ingress Controller to sync Cilium's IngressClass on startup. (Backport PR #28870, Upstream PR #28663, @learnitall)
* Fix IPsec error logs to always have all information needed to identify the XFRM configuration on which the error happened. (Backport PR #29030, Upstream PR #28642, @pchaigno)
* Fix issue causing KVStoreMesh metrics to be included in the dedicated Service/ServiceMonitor when KVStoreMesh is disabled (Backport PR #28759, Upstream PR #28481, @giorio94)
* fix: Correct spire labels identation in helm chart (Backport PR #28759, Upstream PR #28610, @sayboras)
* fixed cilium-operator delete CEC cilium-ingress when other ingressclass resources are created (Backport PR #28759, Upstream PR #28638, @chaunceyjiang)
* Improved event handling for pod events by removing an unnecessary early return, allowing unrelated components to execute correctly, while enhancing ipcache error logging. (Backport PR #29030, Upstream PR #28840, @aanm)
* ingress: cleanup resources on changed ingress class field (Backport PR #29030, Upstream PR #28886, @mhofstetter)
* Print full labelset for all identities in 'cilium ip list' output (Backport PR #28759, Upstream PR #28425, @joestringer)
* Remove AWS-CONNMARK-CHAIN iptable rules when running in ENI mode. (Backport PR #28759, Upstream PR #28676, @nebril)
* spire: add scheduling configurations to helm-chart (Backport PR #28759, Upstream PR #27229, @tvonhacht-apple)
* When the CT entry for a DSR connection is garbage-collected, the corresponding SNAT entry is now also removed. (Backport PR #28870, Upstream PR #28857, @julianwiedmann)
