This edge release introduces a fix for service discovery on endpoints that use hostPorts. Previously, the destination service would return the pod IP for the discovery request which could break connectivity on pod restart. To fix this, direct pod communication for a pod bound on a hostPort will always return the hostIP. In addition, this release fixes a security vulnerability (CVE-2023-2603) detected in the CNI plugin and proxy-init images, and includes a number of other fixes and small improvements. * Addressed security vulnerability CVE-2023-2603 in proxy-init and CNI plugin ([#11296]) * Introduced resource requests/limits for the policy controller resource in the control plane helm chart ([#11301]) * Fixed an issue where an empty `remoteDiscoverySelector` field in a multicluster link would cause all services to be mirrored ([#11309]) * Removed time out from `linkerd multicluster gateways` command; when no metrics exist the command will return instantly ([#11265]) * Improved help messaging for `linkerd multicluster link` ([#11265]) * Changed how hostPort lookups are handled in the destination service. Previously, when doing service discovery for an endpoint bound on a hostPort, the destination service would return the corresponding pod IP. On pod restart, this could lead to loss of connectivity on the client's side. The destination service now always returns host IPs for service discovery on an endpoint that uses hostPorts ([#11328]) * Updated HTTPRoute webhook rule to validate all apiVersions of the resource (thanks @mikutas!) ([#11149]) * Fixed erroneous `skipped` messages when injecting namespaces with `linkerd inject` (thanks @mikutas!)
