Summary

Summary by CodeRabbit

New Features
- Sensors now detect OpenShift MachineConfigPool changes and publish node-role updates.
- Compliance-enabled sensors advertise support for synchronizing scan configurations with Central.
- Compliance scan requests now support creating, updating, rerunning, scheduling, suspending, resuming, and deleting scans, with responses for unsupported or unavailable operations.
- Scan configurations can reflect the cluster’s node roles.
Improvements
- Scan operations use bounded retries to handle transient API errors and conflicts more reliably.

Central advertises compliance scan-configuration sync. The sensor routes compliance requests through a manager and Kubernetes writer. The listener tracks MachineConfigPools and publishes node-role events when the tracked pool set changes.

Changes: Compliance scan configuration sync

Layer / File(s)	Summary
Capability and PubSub contracts `central/sensor/service/service_impl.go`, `pkg/centralsensor/caps_list.go`, `sensor/common/events/`, `sensor/common/pubsub/`, `sensor/kubernetes/sensor/*`, `sensor/kubernetes/complianceoperator/types.go`	Central advertises `ComplianceV2ScanConfigSync` when compliance enhancements are enabled. The sensor adds PubSub events, topics, and lanes, and connects the dispatcher to the compliance manager and handler.
Request processing and manager `sensor/kubernetes/complianceoperator/handler_impl.go`, `sensor/kubernetes/complianceoperator/manager.go`, `sensor/kubernetes/complianceoperator/utils.go`, `sensor/kubernetes/complianceoperator/handler_impl_test.go`	The handler validates and publishes compliance requests. The manager processes sync, apply, and delete requests, handles node-role notifications, and publishes results for the handler to turn into responses. ScanSetting conversion and updates use supplied roles.
Kubernetes operations and retries `sensor/kubernetes/complianceoperator/k8s_operations.go`, `sensor/kubernetes/complianceoperator/retrier.go`, `sensor/kubernetes/complianceoperator/*_test.go`	The writer manages scan resources and synchronization. The retrier applies per-call and overall timeouts, exponential backoff, and conflict handling. Tests cover writer and retry behavior.

MachineConfigPool node-role events

Layer / File(s)	Summary
Pool store and event dispatch `sensor/kubernetes/listener/resources/noderole/store/`, `sensor/kubernetes/listener/resources/store_provider.go`, `sensor/kubernetes/listener/resources/noderole/dispatcher/`, `sensor/kubernetes/listener/resources/dispatcher.go`	A synchronized store tracks MachineConfigPool names. The dispatcher updates the store and publishes `NodeRoleChangeEvent` when the tracked set changes. The registry exposes the dispatcher through its tracing and metrics wrappers.
Informer registration `sensor/kubernetes/listener/informer_sync_tracker.go`, `sensor/kubernetes/listener/listener_impl.go`, `sensor/kubernetes/listener/resource_event_handler.go`	The listener checks whether the MachineConfigPools API resource exists. If it exists, the listener registers an informer and includes it in sync tracking.

Merge Risk: Moderate · previous review c236b

Scan configuration sync can delete existing scan schedules when Central sends an invalid entry, and it can touch labeled resources outside the compliance namespace. Existing scans can also keep stale node roles after the last MachineConfigPool is removed. Fix these data-integrity problems before merging.

Full details: Title check

Explanation

The title "ROX-7596: Adaptive role node configuration" names the main feature: the PR adds custom node-role handling for the compliance operator. The changeset adds a MachineConfigPool store, dispatcher, and listener, and a Manager that reconciles ScanSettings using the stored roles instead of hardcoded master and worker roles. The title is specific and matches the primary change, so it passes. It has a ticket prefix, which is acceptable.

Full details: Description check

Explanation

The description is unchanged from the template and still contains the placeholder text "change me!" in both the Description and the How I validated sections. It gives no explanation of the changes, no test or validation details, and no checked items. The required information is missing, so the description is largely incomplete.

Resolution

Replace both "change me!" placeholders. In the Description section, explain the change: adaptive node-role handling through MachineConfigPool monitoring, the new Manager and pub/sub lanes, and the ComplianceV2ScanConfigSync capability. In How I validated my change, list the unit tests added (retrier, MachineConfigPool store and dispatcher, ScanSetting operations) and any manual validation. Update the checklist items for CHANGELOG, documentation, feature-flag gating, and tests so they reflect the actual state.

Handle node-role change events.

When an MCP changes, no consumer receives the notification, so it cannot trigger role reconciliation. Register a consumer that reads the same MCP store and reconciles the scan settings.

Major · Functional Correctness · Quick win

Gate the startup sync wait on the sync capability that Sensor advertises.

When syncScanConfigsOnStartup is disabled and Central reports ComplianceV2ScanConfigSync, Central sends no sync. waitAndProcessSync() still blocks on the first queued event. Central producers for apply and delete requests inspected here do not check the Sensor capability, so that event can be one of them. processSync rejects it with expected SyncScanConfigs request, logs the error, and publishes no result. Central receives no response for that request.

Use the same condition that makes Central send the sync:
Suggested fix
-	if centralcaps.Has(centralsensor.ComplianceV2ScanConfigSync) {
+	if syncScanConfigsOnStartup.BooleanSetting() && centralcaps.Has(centralsensor.ComplianceV2ScanConfigSync) {
 		m.waitAndProcessSync()

Abort the helper when either timeout expires.

After the first timeout, the helper continues. Its second wait uses the same expired timer and has no timeout that can fire. If ProcessMessage stalls, the test blocks until the Go test timeout ends the run. Calling s.T().Fatal on both timeout paths stops the test at the first expiry.

Suggested fix

 		case <-timer.C:
-			s.Fail("Timed out while waiting for response")
+			s.T().Fatal("Timed out while waiting for response")

Signal response shutdown before waiting for the manager.

If the Central sender stops with two scan results pending, the first result can block in onResult while sending to the unbuffered response channel. The second result then blocks the manager while publishing to the unbuffered result lane. manager.Stop() waits for that manager, but stopSignal is not signaled until the wait ends. Sensor shutdown can therefore hang. Signal stopSignal before calling manager.Stop(). (raw.githubusercontent.com)

Process scan sync after every Central reconnect.

Central sends SyncScanConfigs on each connection when Sensor advertises the capability. waitAndProcessSync() handles only the first sync in the manager’s lifetime. After a reconnect, this switch treats the new sync as an unexpected request and discards it. Scan configurations changed in Central while disconnected therefore remain stale in Kubernetes. Route subsequent sync requests to processSync. (raw.githubusercontent.com)

Review comments at @sensor/kubernetes/complianceoperator/k8s_operations.go:
- Around line 357-361: Scope the resource listing in the retry callback to the
compliance namespace by applying the namespace to the dynamic resource interface
before calling List. Ensure the resulting list is restricted before the sync
deletion pass and MCP reconciliation use it; preserve the existing label
selector and retry behavior.
- Around line 321-324: Update the validation-failure path around
validateUpdateScheduledScanConfigRequest to retain the existing configuration’s
name in inCentralSet before continuing, so the deletion pass preserves its
ScanSetting and ScanSettingBinding while sync still reports the validation
error.
- Around line 51-54: Update the scheduled-scan create path containing the
ScanSettingBinding `Create` call so a failed binding creation does not leave
retries permanently blocked by the already-created ScanSetting: either reconcile
the missing binding after confirming the existing ScanSetting belongs to this
scan, or delete the ScanSetting when binding creation fails. Preserve the
existing retry behavior and do not bind an existing ScanSetting without
verifying ownership.

Review comments at @sensor/kubernetes/complianceoperator/manager.go:
- Around line 255-257: Update the empty-roles branch in the reconciliation flow
to use the fallback master and worker roles from getRoles() instead of returning
early, so existing ScanSettings are reconciled with those roles when the last
MCP disappears.

- Description check:
Replace both "change me!" placeholders. In the Description section, explain the
change: adaptive node-role handling through MachineConfigPool monitoring, the
new Manager and pub/sub lanes, and the ComplianceV2ScanConfigSync capability. In
How I validated my change, list the unit tests added (retrier, MachineConfigPool
store and dispatcher, ScanSetting operations) and any manual validation. Update
the checklist items for CHANGELOG, documentation, feature-flag gating, and tests
so they reflect the actual state.

Recover a ScanSetting left behind by a failed binding create.

If the ScanSetting create succeeds and the ScanSettingBinding create fails, a retried scheduled-scan create fails at the ScanSetting step with AlreadyExists. It never creates the binding. The scan stays unbound until an update request for the same scan name creates the binding.

Make the create path handle this state. Either reconcile an existing ScanSetting with its missing binding, or delete the ScanSetting when the binding create fails. Reconciling must confirm that the existing ScanSetting belongs to this scan before it binds to it.

Keep an invalid Central configuration out of the deletion pass.

When validation rejects a configuration that already exists in Kubernetes, this continue omits its name from inCentralSet. The deletion pass then removes its ScanSetting and ScanSettingBinding, even though sync reports a validation error. Abort deletion when validation fails, or retain the rejected configuration’s name before continuing. (raw.githubusercontent.com)

Scope resource listing to the compliance namespace.

Resource(...).List(...) omits .Namespace(ns), so the dynamic client lists matching resources across namespaces. During sync, the deletion pass removes matching resources from other namespaces because their names cannot occur in the current namespace’s inCentralSet. MCP reconciliation also attempts to update those resources through the current namespace. List only the compliance namespace before either operation. (raw.githubusercontent.com)

Restore default roles when the last MCP disappears.

When the last tracked MCP is removed, this branch skips reconciliation. Existing ScanSettings retain their former custom roles, although getRoles() now returns master and worker for new or updated ScanSettings. Reconcile with the fallback roles instead of leaving existing scans on stale roles. (raw.githubusercontent.com)
