Honor apiserver tlsAdherence and inject --tls-min-version / --tls-cipher-suites onto the trust-manager Deployment when required.
Apply apiserver tlsSecurityProfile to library-go HTTPServingInfo at startup when tlsAdherence requires it, and wire serving-cert mounts for the metrics Service.
Turn on dynamic metrics serving certificates for controller, webhook, and cainjector so --metrics-tls-* profile flags apply to real TLS on :9402, with RBAC for the shared metrics CA secret.
Set features.operators.openshift.io/tls-profiles to true now that operand, operator metrics, and trust-manager webhook TLS are wired.
Keep the bundled ClusterServiceVersion aligned with the manifests base tls-profiles feature claim.
Operator cmd imports k8s.io/apiserver/pkg/server for ServingInfo TLS wiring; tidy expects it as a direct require so verify-deps stays clean.
Expand ResolveHonoredTLSProfile and trust-manager TLS tests for adherence, error propagation, and serving guards; clarify ObjectGetter matches CtrlClient.
Add operand Day-2/cipher-strip and Legacy HTTPS-metrics e2e, harden APIServer profile patches for Modern/Intermediate union fields, and extend serving/adherence unit tests in place of a live :8443 dial.
Matches() returned false on the first type-matching condition with an unexpected status even when Any=true, so an unrelated condition (e.g. *-static-resources-Degraded=False) could mask a later matching one (e.g. *-deploymentDegraded=True), causing verifyOperatorStatusCondition to time out instead of succeeding. This caused the flaky "Overrides test ... cainjector override args" e2e failure where the operator had already correctly degraded the deployment. Gate the mismatch short-circuit behind !Any and add a regression test reproducing the exact condition ordering seen in CI.
Drop the duplicate prometheus.io/scheme annotation from generated deployments, emit the metrics dynamic-serving Role/RoleBinding from jsonnet, and expand withOperandMetricsTLS unit coverage.
Reconcile trust-manager on cluster APIServer TLS field changes only, require a single container in the operand metrics TLS hook, and cover Old/Custom webhook TLS profiles.
TrustManager is a cluster singleton. Jobs that pre-create it should not fail Feature:TLSProfile e2e on AlreadyExists.
PollUntilContextTimeout treats a Get 504 as fatal, so TrustManager AfterAll failed after a successful TLS profile spec. Retry timeout and other transient API errors until the wait budget expires.
The operator ClusterRole already grants get/list/watch from the cert-manager controller marker.
Map the cluster TLS security profile to trust-manager's new --tls-curve-preferences webhook flag (added upstream in trust-manager v0.25.0 / cert-manager/trust-manager#1089), restricting TLS key-exchange groups the same way cluster TLS profile already restricts min version and cipher suites. - Add tlsprofile.CurvePreferencesArgValue(), rendering DefaultCurvePreferences (X25519, P-256, P-384, P-521) as the numeric comma-separated form trust-manager/kube-apiserver expect. - TrustManagerWebhookTLSArgs now always emits --tls-curve-preferences for both TLS 1.2 and TLS 1.3: unlike cipher suites, Go still honors CurvePreferences under TLS 1.3, so the flag is intentionally excluded from the TLS-1.3 cipher-strip list (TrustManagerCipherSuiteArgKeys). - Add TestTrustManagerCipherSuiteArgKeysOmitsCurvePreferences to guard that invariant going forward. - Extend existing table-driven tests in tlsprofile_test.go and deployment_tls_test.go to assert the new flag, including a merge case proving a stale --tls-curve-preferences value is correctly overwritten when a profile is applied, and left untouched when it is not (nil spec). Requires the trust-manager operand bump to v0.25.0 (CM-1367, openshift#495): --tls-curve-preferences does not exist on the v0.20.3 operand this repo currently ships, so this must not merge/rollout ahead of that bump or the webhook pod will fail flag parsing.

Bump trust-manager before enabling --tls-curve-preferences.
When the shipped operand remains v0.20.3, TrustManagerWebhookTLSArgs adds a flag that this version does not support. Under StrictAllComponents, the trust-manager webhook receives the flag, fails argument parsing, and enters CrashLoopBackOff. Merge the trust-manager v0.25.0 operand bump first, or gate this flag on the deployed operand version.

Summary
Map the cluster TLS security profile to trust-manager's new
--tls-curve-preferenceswebhook flag (added upstream in trust-manager v0.25.0, cert-manager/trust-manager#1089), restricting TLS key-exchange groups the same way the cluster TLS profile already restricts min version and cipher suites for the trust-manager webhook.tlsprofile.CurvePreferencesArgValue(), renderingDefaultCurvePreferences(X25519, P-256, P-384, P-521) as the numeric comma-separated form trust-manager/kube-apiserver expect (29,23,24,25).TrustManagerWebhookTLSArgsnow always emits--tls-curve-preferences=...for both TLS 1.2 and TLS 1.3. Unlike cipher suites, Go still honorsCurvePreferencesunder TLS 1.3, so the flag is intentionally excluded from the TLS-1.3 cipher-strip list (TrustManagerCipherSuiteArgKeys).tlsprofile_test.goanddeployment_tls_test.goto assert the new flag across Old/Intermediate/Modern/Custom profiles, including a merge case proving a stale--tls-curve-preferencesvalue is correctly overwritten when a profile is applied, and left untouched when it is not (nil spec / non-strict adherence).TestTrustManagerCipherSuiteArgKeysOmitsCurvePreferencesto guard the TLS-1.3 exclusion invariant going forward.This branch is built on top of
trustmanager_tls_impl(#466), so this diff includes #466's commits until that merges. It is not based on #495.However, this PR has a runtime dependency on #495 (CM-1367, trust-manager operand bump to v0.25.0):
--tls-curve-preferencesdoes not exist on the v0.20.3 operand this repo currently ships. If this reaches a cluster running the older operand undertlsAdherence: StrictAllComponents, the trust-manager webhook pod will fail flag parsing and CrashLoopBackOff.Do not merge this PR until both #466 and #495 are merged to master. This mirrors the same ordering constraint #495 already calls out for #494 (
