2018-05-25nvme-rdma: stop admin queue before freeing itJianchao Wang1-4/+6
For any failure after nvme_rdma_start_queue in nvme_rdma_configure_admin_queue, the admin queue will be freed with the NVME_RDMA_Q_LIVE flag still set. Once nvme_rdma_stop_queue is invoked, that will cause a use-after-free. BUG: KASAN: use-after-free in rdma_disconnect+0x1f/0xe0 [rdma_cm] To fix it, call nvme_rdma_stop_queue for all the failed cases after nvme_rdma_start_queue.

2018-05-25nvme-pci: Fix AER reset handlingKeith Busch1-9/+5
The nvme timeout handling doesn't do anything if the pci channel is offline, which is the case when recovering from PCI error event, so it was a bad idea to sync the controller reset in this state. This patch flushes the reset work in the error_resume callback instead when the channel is back to online. This keeps AER handling serialized and can recover from timeouts.

Split the completion of events into a two part process: 1) Reap the events inside the queue lock 2) Complete the events outside the queue lock Since we never wrap the queue, we can access it locklessly after we've updated the completion queue head.

2018-05-16nbd: fix how we set bd_invalidatedJosef Bacik1-4/+3
bd_invalidated is kind of a pain wrt partitions as it really only triggers the partition rescan if it is set after bd_ops->open() runs, so setting it when we reset the device isn't useful. We also sporadically would still have partitions left over in some disconnect cases, so fix this by always setting bd_invalidated on open if there's no configuration or if we've had a disconnect action happen, that way the partition table gets invalidated and rescanned properly.

2018-05-11nvme/pci: Sync controller reset for AER slot_resetKeith Busch1-2/+9
AER handling expects a successful return from slot_reset means the driver made the device functional again. The nvme driver had been using an asynchronous reset to recover the device, so the device may still be initializing after control is returned to the AER handler. This creates problems for subsequent event handling, causing the initializion to fail. This patch fixes that by syncing the controller reset before returning to the AER driver, and reporting the true state of the reset.
