Full details: Test Structure And QualityExplanation The new tests cover related credential-rotation behavior and add bounded polling, and the created pull-test pods plus the modified auth Secret have cleanup paths. However, several assertions introduced by the pull request have no diagnostic message, including Resolution Add a meaningful failure message to every new assertion, including the relevant test-case name or resource/action. Use a bounded cleanup context for pull-test pod deletion, check the deletion error, and report it. Keep the existing bounded contexts for pod creation, polling, Secret restoration, and rollout waits. Full details: No-Weak-CryptoExplanation The pull request adds a non-constant-time comparison of an authentication token at Resolution Replace the direct token equality with a constant-time comparison. For example, type-check Full details: No-Sensitive-Data-In-LogsExplanation The pull request adds a sensitive-data logging path in the IRI e2e test.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Add conflict retry and a bounded context for the Secret update.
authSecret originates from the controller's Secret lister (see pkg/controller/internalreleaseimage/internalreleaseimage_controller.go line 548), so its resourceVersion can be stale. A concurrent write then makes this Update fail with a 409 conflict and fails the whole sync. The rest of the controller wraps writes in retry.RetryOnConflict(updateBackoff, ...).
Also pass a context with a deadline instead of context.TODO(). A blocking API call without a timeout holds a controller worker.

…emplate controller Replace if iriSecretsInformer != nil / if iriInformer != nil guards with fgHandler.Enabled(FeatureGateNoRegistryClusterInstall) checks, making the intent explicit: IRI event handlers and the merger are only wired when the feature gate is on, not as a side-effect of nil informers being passed.

Add verifyCanPullFromIRI helper that creates a pod with imagePullPolicy:Always using the IRI release image (pulled from the local IRI registry, not quay.io) and verifies the kubelet can authenticate and pull it. This exercises the full kubelet credential lookup path (/var/lib/kubelet/config.json) rather than just raw HTTP auth via curl exec. Add getIRIReleasePullSpec helper that queries /v2/openshift/release-images/tags/list on the IRI registry and constructs the local pullspec (api-int.<baseDomain>:22625/openshift/release-images:<version-tag>). Add pre-rotation and post-rotation pull checks to TestIRIAuth_CredentialRotation. The existing curlIRIRegistry checks are retained for old-credential rejection verification. Assisted-by: Claude Sonnet 4.6 <noreply@anthropic.com>
…edentials rejected
The old-credential 401 check after rotation was running immediately after
observing a single api-int 200 from curlIRIRegistry. Since api-int is a VIP
that load-balances across masters, this only proved one backend had the new
htpasswd; the 401 probe could land on an unrotated master and return 200.
Wait for WaitForPoolCompleteAny("master") before the old-credential assertion
to ensure all masters have applied the new htpasswd before we check rejection.
Assisted-by: Claude Sonnet 4.6 <noreply@anthropic.com>
Three fixes for reliability of the post-rotation verifyCanPullFromIRI check: 1. Retry getIRIReleasePullSpec until tags are available. After credential restores the IRI registry can take a moment to stabilize; querying tags immediately can return an empty list causing a spurious test failure. 2. Wait for /var/lib/kubelet/config.json to contain the new IRI credentials before creating the pull-test pod. Credential rotation triggers two sequential MC rollouts (02-master for htpasswd, 00-master for pull secret); WaitForPoolCompleteAny returns after the first, so without this wait the pod is created before the pull secret is updated. 3. Retry the pull-test pod if it hits ImagePullBackOff. CRI-O can cache authentication failures briefly; deleting and recreating the pod forces a fresh authentication attempt with the updated credentials.

Use a bounded context for Secrets.Update.
reconcileHtpasswd calls Secrets.Update with context.TODO(). The worker does not propagate its Run context, and the production client leaves rest.Config.Timeout at its zero value, which client-go defines as no timeout. A stalled API request can therefore keep the reconciliation worker blocked without a deadline.
Pass a bounded context into reconcileHtpasswd and use it for Secrets.Update.

Wait for restored credentials before cleanup returns.
WaitForPoolCompleteAny returns on the first poll when MachineConfigPoolUpdated=True; it does not verify that the condition reflects the cleanup update. The restored Secret can still be pending in the IRI controller, which renders htpasswd, or in the template controller, which merges password into the kubelet pull secret. The helper can also return after the first rollout while the later 00-master rollout has not updated /var/lib/kubelet/config.json.
Before cleanup returns, wait for the original registry credentials to work on the node and for the original kubelet authentication entry to appear in /var/lib/kubelet/config.json. Then wait for the master pool to complete.

- What I did
This replicates the implementation in #5810. This newer version of the implementation does not perform featuregate checks since this feature has been promoted to default.
Implement credential rotation that accepts brief registry downtime.
When an admin updates iriAuthSecret.Data["password"], the controller:
Detects the mismatch between password and htpasswd (via bcrypt compare)
Generates a new bcrypt hash and updates iriAuthSecret.Data["htpasswd"]
Re-renders the master MachineConfig with the new htpasswd
Updates the global pull secret with the new credentials
MCD rolls out the updated MC; brief downtime for IRI registry during
rollout is accepted
Key changes:
Add NoneStatusAction for /etc/iri-registry/auth/htpasswd in NodeDisruptionPolicy
(Distribution registry re-reads htpasswd on mtime change, no restart needed)
Add unit tests for helpers and reconcileAuthSecret
Add e2e tests: unauthenticated 401, authenticated 200, and full rotation flow
(tests use ExecCmdOnNode via MCD pod to reach api-int:22625 in CI)
- How to verify it
Update the password to trigger the rotation to start:
oc -n openshift-machine-config-operator patch secret internal-release-image-registry-auth
--type merge -p '{"data":{"password":"'$(echo -n "new-password" | base64)'"}}'
Verify the /etc/iri-registry/auth/htpasswd has been updated.
Verify iri-registry works new credentials after rollout is complete.
Verify global pull-secret contains the new credentials after rollout is complete.
- Description for the changelog
Support credential rotation in IRI registry.
