Fail closed when the Machine list fails.
getMachinesForNodePool can fail earlier in this function without returning. In that case, machines is nil and len(machines) is zero. Line 460 then bypasses the safety limit and Line 478 can call capi.Reconcile, which can create more Machines while the actual count is unknown.
Return an error or requeue before CAPI reconciliation when Machine listing fails. This preserves the circuit breaker during API errors.

looks like this duplicates some of the behavior below (separate calls to pauseMachineSet and pauseMachineDeployment).
My preference is to leave this out of this PR and just keep it focused on preserving the infraID from the hcp.
There was a problem hiding this comment.
Followed the suggestion and updated the PR as per that.
CEL already rejects infraID removal, but if that check is bypassed the controller generated a new infraID and CAPI reprovisioned against a second cluster identity. Treat the HostedControlPlane infraID as source of truth once it exists, and do not overwrite it on the HCP. Signed-off-by: Dhruv Gautam <dgautam@redhat.com>

What this PR does / why we need it:
Changing or clearing HostedCluster
spec.infraIDcaused the controller to mint a new cluster identity. CAPI then provisioned against that new identity.CEL already rejects
infraIDremoval (OCPBUGS-98065). This PR makes the HostedControlPlane the source of truth forinfraIDonce it exists:infraID, copy it onto the HostedCluster (empty or conflicting values)infraIDonce it is setinfraIDonly on first create (no HostedControlPlane yet)NodePool pause/delete still pauses and deletes all NodePool-owned CAPI resources, not only canonical names, so leftover MachineSets from rollouts cannot keep creating Machines after the NodePool is paused or deleted.
This PR does not add a HyperShift machine-count circuit breaker. Unbounded Machine creation in CAPI belongs in CAPI.
Which issue(s) this PR fixes:
Fixes https://redhat.atlassian.net/browse/OCPBUGS-98066
Special notes for your reviewer:
Admission-time CEL immutability for
infraIDalready landed in #9102 (OCPBUGS-98065). This is the controller-side restore if that check is bypassed.Checklist:
