📝 WalkthroughSummary by CodeRabbit
WalkthroughThe application detects OpenShift API server TLS settings, applies them to metrics and webhook servers, and stops manager execution when settings change. Vendored OpenShift TLS and crypto packages provide supporting utilities. OpenShift API models and RBAC metadata are refreshed. ChangesOpenShift TLS profile integration
Estimated code review effort: 5 (Critical) | ~100 minutes Merge Risk: 🟠 High · up to The PR adds cluster-driven TLS configuration and certificate/key handling, but the current code can ignore the cluster’s TLS adherence policy, permit weak RSA keys, reject or accept invalid configuration incorrectly, and panic on empty hostname inputs. These risks can cause non-compliant or weakened TLS and runtime failures, so the PR is not merge-ready until the major issues are fixed. Sequence Diagram(s)sequenceDiagram

Fetch the OpenShift APIServer TLS security profile at startup and apply it to both webhook and metrics servers. On non-OpenShift clusters, fall back to Go defaults gracefully via meta.IsNoMatchError detection. Register a SecurityProfileWatcher that cancels the manager context on TLS profile changes, triggering a graceful restart so the operator always runs with the cluster's current TLS policy.

Pick up openshift/controller-runtime-common#22 which adds TLS groups/curve preferences (including PQC groups like X25519MLKEM768) to the central TLS profile configuration. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Inline comments:
In `@vendor/github.com/openshift/api/config/v1/types_infrastructure.go`:
- Around line 846-848: Add per-label DNS validation limiting every label to 63
characters for UniverseDomain and the three KMS fields using the existing
validators at
vendor/github.com/openshift/api/config/v1/types_infrastructure.go:846-848 and
vendor/github.com/openshift/api/config/v1/types_kmsencryption.go:66,79,303.
Update the validation rules for UniverseDomain, both reference Name fields, and
ServerName; all four sites require direct changes.
In `@vendor/github.com/openshift/api/config/v1/types_ingress.go`:
- Around line 282-283: The XValidation rules on the label-key field must
validate the name segment separately from the optional prefix. Update the rules
near the label-key schema so the segment after the slash is 1–63 characters and
the DNS prefix before the slash is limited to 253 characters, while preserving
the existing qualified-name character and boundary requirements.
In `@vendor/github.com/openshift/library-go/pkg/crypto/cert_config.go`:
- Around line 99-102: Validate that the hostname set is non-empty immediately
after converting it with sets.List in both certificate-creation methods, and
return an appropriate error before any index-zero access. Preserve the existing
certificate generation flow for non-empty sets, including uses of
sortedHostnames[0].
In `@vendor/github.com/openshift/library-go/pkg/crypto/keygen.go`:
- Around line 42-47: Update RSAKeyPairGenerator.GenerateKeyPair to validate the
resolved bits value after applying the keyBits default and return an error when
it is below 2048, before calling rsa.GenerateKey.
- Around line 102-117: Update SubjectKeyIDFromPublicKey for RSA keys to hash the
complete DER encoding from x509.MarshalPKCS1PublicKey(pub), including both
modulus and exponent, while preserving the existing ECDSA and unsupported-type
handling. Add a regression test using a generated CA certificate to verify the
computed identifier matches the certificate’s SubjectKeyId.
In `@vendor/github.com/openshift/library-go/pkg/crypto/tls_adherence.go`:
- Around line 16-22: Update the TLS profile setup in cmd/main.go to also
retrieve TLSAdherencePolicy, apply TLSProfileSpec only when
ShouldHonorClusterTLSProfile returns true, and configure the watcher to restart
when that effective adherence decision changes.

What
Integrate OpenShift central TLS security profile support using
controller-runtime-common/pkg/tls, the ecosystem-standard library for TLS profile adherence.Why
OCP 5.0 requires all operators to dynamically inherit TLS settings from
APIServer.spec.tlsSecurityProfile(RHWA-555/RHWA-1309). This is a release blocker for TLS adherence compliance.How
