Technical summary

In the Linux kernel, the following vulnerability has been resolved: nvme-fc: Do not cancel requests in io target before it is initialized A new nvme-fc controller in CONNECTING state sees admin request timeout schedules ctrl->ioerr_work to abort inflight requests. This ends up calling __nvme_fc_abort_outstanding_ios() which aborts requests in both admin and io tagsets. In case fc_ctrl->tag_set was not initialized we see the warning below. This is because ctrl.queue_count is initialized early in nvme_fc_alloc_ctrl(). nvme nvme0: NVME-FC{0}: starting error recovery Connectivity Loss INFO: trying to register non-static key. The code is fine but needs lockdep annotation, or maybe lpfc 0000:ab:00.0: queue 0 connect admin queue failed (-6). you didn't initialize this object before use? turning off the locking correctness validator.

Also make sure to cancel ctrl->ioerr_work before removing io tagset.
