The allocrunner has a facility for passing data written by allocrunner hooks to taskrunner hooks. Currently the only consumers of this facility are the allocrunner CSI hook (which writes data) and the taskrunner volume hook (which reads that same data). The allocrunner hook for CSI volumes doesn't set the alloc hook resources atomically. Instead, it gets the current resources and then writes a new version back. Because the CSI hook is currently the only writer and all readers happen long afterwards, this should be safe but #16623 shows there's some sequence of events during restore where this breaks down. Refactor hook resources so that hook data is accessed via setters and getters that hold the mutex. |
