Cilium - v1.14.6


We are pleased to release Cilium v1.14.6.

This release includes various bugfixes and performance enhancements. The amount of trace events is reduced when monitor aggregation is enabled, allowing to improve pod-to-pod performance with tunneling and IPsec. An inconsistency in the node manager is fixed, which led to incorrect masquerading of traffic to node internal IP addresses. Other fixes include fixes for mTLS, DNS proxy, datapath, etc.

Summary of Changes

Minor Changes:
* Add Proxy l7 metrics proxy_type label and and Cleanup (Backport PR #29703, Upstream PR #27863, @tommyp1ckles)
* Reduce "stale identity observed" warnings (Backport PR #29863, Upstream PR #27894, @leblowl)

* Add default toleration for SPIRE agent on control plane nodes (Backport PR #30198, Upstream PR #28947, @meyskens)

* cilium-preflight: use the k8s node name instead of relying on hostname (Backport PR #29996, Upstream PR #29809, @marseel)

(Backport PR #30221, Upstream PR #29986, @qmonnet)
* Fix and prevent future bugs limiting pod-to-pod network performance under high load when tunneling and IPSec are both enabled. (Backport PR #29996, Upstream PR #29616, @learnitall)
