Fixes #8895

What this PR does

Increases the MaxItems limit for RateLimitSelectCondition.Headers from 16 to 64, allowing users to specify more header matching rules in rate limit configurations.

Why 64?

This aligns with the existing HTTPHeaderFilter pattern already defined in this codebase (shared_types.go:1031), which also increased the limit from 16 to 64 for the same reason.

Changes

  • api/v1alpha1/ratelimit_types.go: Changed +kubebuilder:validation:MaxItems=16 to +kubebuilder:validation:MaxItems=64 on the Headers field of RateLimitSelectCondition
  • Added a comment noting this can be reverted once upstream Gateway API supports more than 64 items

Do we need this in the API docs? Maybe just create a follow up issue to track this if required.

… MaxItems change

Running make generate updated the pre-generated CRD YAML files and API docs
to reflect the MaxItems increase from 16 to 64. Without these changes, clusters
installed from the charts would still reject headers lists longer than 16.

* fix: respect backend endpoint hostname for health checks (#8929)

* fix: respect backend endpoint hostname for health checks

### Summary
- Keep BackendTrafficPolicy HTTP health check hostnames as explicit cluster-level hosts, and leave route-derived host fallback to xDS cluster translation.
- Preserve Backend endpoint hostnames as per-endpoint overrides via Endpoint.HealthCheckConfig.hostname, ahead of the route fallback.
- Update gatewayapi/xDS fixtures, release notes, and generated API docs/CRDs for the host selection order.

### Test plan
- go test ./internal/ir
- go test ./internal/xds/translator
- go test ./internal/gatewayapi -run TestTranslate/backendtrafficpolicy
- go test ./internal/gatewayapi -run TestTranslate/(clienttrafficpolicy-http-health-check|envoyextensionpolicy-with-extproc-with-retries|envoyextensionpolicy-with-extproc-with-traffic-features|envoyproxy-accesslog-with-traffic|envoyproxy-tracing-backend-uds|envoyproxy-tracing-backend|securitypolicy-with-jwt-backendcluster|securitypolicy-with-jwt-backendsettings)

* fix(helm): propagate commonLabels to RBAC resources (#8818)

* feat(helm): propagate commonLabels to RBAC resources

Issue #8817 reported that 'helm template ... --set
commonLabels.custom-label=custom-value' left ClusterRole,
ClusterRoleBinding, Role, and RoleBinding resources unlabelled.
The other resources in the chart already include 'eg.labels' in
their metadata - which picks up 'commonLabels' via the helper
at _helpers.tpl:43 - but envoy-gateway-rbac.yaml didn't set any
labels block.

Add 'labels: {{- include "eg.labels" . | nindent 4 }}' on every
Role / RoleBinding / ClusterRole / ClusterRoleBinding declared in
envoy-gateway-rbac.yaml. Matches the existing labels pattern used
in certgen-rbac.yaml and envoy-gateway-deployment.yaml. Scopes are
'$' inside the watched-namespaces 'range' and '.' at the template
root, same rule the helper block inside the file already used.

Verified locally with:
  helm dependency update charts/gateway-helm
  envsubst < charts/gateway-helm/values.tmpl.yaml > \
    charts/gateway-helm/values.yaml
  helm template eg charts/gateway-helm \
    --set commonLabels.custom-label=custom-value | yq ...

All four RBAC resources now emit 'custom-label: custom-value' in
their metadata.labels, matching the issue's repro steps. Cert-gen
RBAC resources already carried it; this PR brings the core
envoy-gateway RBAC set into parity.

Fixes #8817

* fix(translator): set ListenerSet and listener Accepted:True for InvalidCertificateRef (#8871)

* fix(translator): set ListenerSet and listener Accepted:True for InvalidCertificateRef

When a ListenerSet listener has an unresolvable TLS certificate reference
(InvalidCertificateRef or RefNotPermitted), Accepted: False was incorrectly
set on both the listener and ListenerSet object. The Gateway API spec places
InvalidCertificateRef exclusively under ResolvedRefs, not Accepted — a missing
certificate is a reference resolution concern, not a structural one.
