- Around line 2452-2460: Update the reinstalled closure to base recovery on
whether cleanup removed resources, not solely on the current CSV failure reason.
Ensure Failed-to-Pending recovery can restore missing RBAC after the reason
changes; use a cleanup marker or invoke reinstallPlanSteps for the relevant
recovery branches, resetting only steps whose owned resources are missing.

When a CSV fails because of its OperatorGroup, OLM left the resources of the operator on the cluster. The three reasons are UnsupportedOperatorGroup, InterOperatorGroupOwnerConflict and CannotModifyStaticOperatorGroupProvidedAPIs. The last two deleted the Deployments of the install strategy, the first one deleted nothing: a Succeeded operator whose OperatorGroup starts to target a namespace set its install modes do not support keeps running with its cluster-wide RBAC while its CSV reports Failed. The ServiceAccount, Roles, RoleBindings, ClusterRoles and ClusterRoleBindings that the InstallPlan created stayed in every case, because only the CSV finalizer removed them. Clean up on failure. cleanupFailedCSV runs on every sync of a CSV that is Failed for one of the three reasons. It deletes the Deployments the CSV owns, unless the CSV serves an APIService or a CRD conversion webhook, and the webhook configurations of the CSV. When the InstallPlan that installed the CSV is Complete and every step manifest of the plan can be applied again, it reads the objects of the Role, RoleBinding, ClusterRole and ClusterRoleBinding steps, marks the steps of the objects that exist and that the CSV owns NotPresent, writes the plan status, and then deletes those objects with a UID precondition. The plan stays Complete. Objects that are already gone or that another owner holds are left alone and their steps keep their status. A mark is taken back when the object disappeared between the read and the delete, or when another owner holds the name now, so a binding an administrator removed or replaced is not brought back. ServiceAccounts are never deleted, the OperatorGroup scoped ServiceAccount can be one of them. InstallPlan execution is at least once: a catalog-operator sync that works from a stale Installing copy of a plan that is already Complete creates the objects again. The cleanup therefore repeats on every sync and never skips a step because it is already marked. While the plan is still Installing the CSV is requeued. Without such a plan, or when a step manifest refers to an unpacked bundle ConfigMap that is gone, the objects stay: nothing could put them back. Reinstall on recovery. On every sync of a Pending or Failed CSV, before the requirements check, a Complete InstallPlan with NotPresent steps for the CSV goes back to Installing with a fresh start time. The catalog-operator executes those steps again, with its usual client and scoped ServiceAccount handling, and the plan returns to Complete. A plan without NotPresent steps is left alone. The InstallPlan status is the only record of the cleanup. Only the catalog-operator and the olm-operator write it, the aggregated edit role grants installplans but not installplans/status. The plan that installed the CSV is found by the CSV step in that status, not by the spec, which users can write. The RBAC is not regenerated from the CSV spec on purpose: the spec is user-editable and the olm-operator never created RBAC from it. Doing so would let anyone who can write a CSV obtain arbitrary cluster permissions by making the CSV fail and recover, and it would bypass the OperatorGroup scoped ServiceAccount. Objects of the plan carry owner labels, cluster-scoped ones have no owner reference, so syncObject now requeues the owner CSV by label too. A stale plan execution that creates them again then triggers the next cleanup at once instead of at the next resync. Known limitation: the catalog-operator keeps five InstallPlans per namespace. If the plan of a Failed CSV is garbage collected after the cleanup ran, recovery stops at Pending/RequirementsNotMet and the CSV has to be deleted so the Subscription installs it again. Not covered: bundle objects, APIServices, copied CSVs and the Roles copied into target namespaces. Fixes OCPBUGS-97599.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win
Refresh plan.ResourceVersion after the first UpdateStatus. The mark rollback at Line 203 otherwise always conflicts.
Line 178 discards the object that UpdateStatus returns. The API server increments the InstallPlan resourceVersion on that write. The second UpdateStatus at Line 203 then sends the stale resourceVersion from the original List. When changed and unconfirmed are both true, a real API server rejects that write with 409 Conflict. The fake clientset does not check resourceVersion, so TestFailedCSVCleanupObjectGoneBeforeDelete passes but does not exercise this case.
Result: the rollback of the mark (v.step.Status = StepStatusPresent) is never stored. The next sync cannot repair it. getStepObject returns NotFound, the loop skips the step, and the step stays NotPresent. reinstallPlanSteps then reopens the plan, and the catalog-operator recreates an object that another actor deleted. The comment at Lines 193-194 says the code must prevent exactly this.
The trigger needs a delete race. The failure is deterministic once that race occurs.

Description of the change:
Remove the resources of a CSV that fails because of its OperatorGroup, and
create them again when the CSV recovers.
cleanupFailedCSVruns on every sync of a CSV that isFailedwith reasonUnsupportedOperatorGroup,InterOperatorGroupOwnerConflictorCannotModifyStaticOperatorGroupProvidedAPIs. It deletes the Deploymentsthe CSV owns, unless the CSV serves an APIService or a conversion webhook,
and the webhook configurations of the CSV. When the InstallPlan that
installed the CSV is
Completeand every step manifest of the plan can beapplied again, it reads the objects of the Role, RoleBinding, ClusterRole
and ClusterRoleBinding steps, marks the steps of the objects that exist and
that the CSV owns
NotPresent, writes the plan status, then deletes thoseobjects with a UID precondition. The plan stays
Complete. ServiceAccountsare never deleted. Objects that are gone or that another owner holds keep
their step status, and a mark is taken back when the object disappeared
between the read and the delete. The cleanup repeats on every sync, because InstallPlan
execution is at least once and a stale catalog-operator sync can create the
objects again. While the plan still runs, the CSV is requeued after 10 s.
Errors are returned so the sync is retried.
reinstallPlanStepsruns on every sync of aPendingorFailedCSV,before the requirements check. When the plan has
NotPresentsteps for the CSV, itclears
status.startTimeand moves the plan toInstalling. Thecatalog-operator executes the steps again and the plan returns to
Complete. A plan withoutNotPresentsteps is left alone.UnsupportedOperatorGroupnow deletes the Deployments like the two otherreasons.
cleanupCSVDeploymentschecks that the CSV owns the Deployment,keeps it when the CSV serves an APIService (spec or live) or a conversion
webhook, and returns errors.
syncObjectrequeues the owner CSV of objects that carry the CSV ownerlabels, not only of objects with an owner reference. Cluster-scoped RBAC
from the plan has labels only.
pkg/controller/operators/olm/csv_cleanup.go, unit tests incsv_cleanup_test.go, one e2e spec inoperator_groups_e2e_test.go.Motivation for the change:
A Succeeded operator whose OperatorGroup starts to target a namespace set its
install modes do not support kept running, with its cluster-wide RBAC, while
its CSV reported
Failed. The RBAC the InstallPlan created stayed on thecluster for every failed installation until the CSV was deleted. See
OCPBUGS-97599.
Architectural changes:
The olm-operator writes the status of an InstallPlan for the first time. The
InstallPlan status is the record of the cleanup and the hand-over to the
catalog-operator, which creates the objects again with its usual logic and
scoped ServiceAccount. Only the two controllers write that status: the
aggregated edit role grants
installplansbut notinstallplans/status.The plan that installed the CSV is found by the CSV step in that status, not
by
spec.clusterServiceVersionNames, which users can write.The RBAC is not regenerated from the CSV spec. The spec is user-editable and
the olm-operator never created RBAC from it. Regenerating from the spec would
let anyone who can write a CSV obtain arbitrary cluster permissions by making
the CSV fail and recover, and it would bypass the OperatorGroup scoped
ServiceAccount. Because recovery only reopens steps the cleanup marked,
objects an administrator removed by hand are not created again.
One case gets worse than today: the catalog-operator keeps five InstallPlans
per namespace. If a CSV stays
Failedlong enough for later installs in thesame namespace to garbage collect its plan after the cleanup ran, recovery
stops at
Pending/RequirementsNotMet. Deleting the CSV makes theSubscription resolve again and reinstall. Before this change the RBAC stayed
and the CSV recovered on its own. If this trade-off is not acceptable, the
cleanup can be limited to Deployments and webhooks.
Not covered, pre-existing: bundle objects, APIServices, copied CSVs and the
Roles the OperatorGroup sync copies into target namespaces.
