nvme-fc: Do not cancel requests in io target before it is initialized
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. Workqueue: nvme-reset-wq nvme_fc_ctrl_ioerr_work [nvme_fc] Call Trace: dump_stack_lvl+0x57/0x80 register_lock_class+0x567/0x580 __lock_acquire+0x330/0xb90 lock_acquire.part.0+0xad/0x210 blk_mq_tagset_busy_iter+0xf9/0xc00 __nvme_fc_abort_outstanding_ios+0x23f/0x320 [nvme_fc] nvme_fc_ctrl_ioerr_work+0x172/0x210 [nvme_fc] process_one_work+0x82c/0x1450 worker_thread+0x5ee/0xfd0 kthread+0x3a0/0x750 ret_from_fork+0x439/0x670 ret_from_fork_asm+0x1a/0x30 Update the check in __nvme_fc_abort_outstanding_ios() confirm that io tagset was created before iterating over busy requests. Also make sure to cancel ctrl->ioerr_work before removing io tagset.
