| * scsi: lpfc: remove left-over BUILD_NVME definesHannes Reinecke2019-10-182-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | The BUILD_NVME define never got defined anywhere, causing NVMe commands to be treated as SCSI commands when freeing the buffers. This was causing a stuck discovery and a horrible crash in lpfc_set_rrq_active() later on.

Since scsi_eh_prep_cmnd() and scsi_eh_restore_cmnd() do not save/restore the original command resid, the value returned on failure of the original command is lost and replaced with the value set by the execution of the request sense command. This value may in many instances be unaligned to the device sector size, causing sd_done() to print a warning message about the incorrect unaligned resid before the command is retried. Fix this problem by saving the original command residual in struct scsi_eh_save using scsi_eh_prep_cmnd() and restoring it in scsi_eh_restore_cmnd(). In addition, to make sure that the request sense command is executed with a correctly initialized command structure, also reset the residual to 0 in scsi_eh_prep_cmnd() after saving the original command value in struct scsi_eh_save.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | storvsc doesn't use a dedicated hardware queue for a given CPU queue. When issuing I/O, it selects returning CPU (hardware queue) dynamically based on vmbus channel usage across all channels. This patch advertises num_present_cpus() as number of hardware queues. This will have upper layer setup 1:1 mapping between hardware queue and CPU queue and avoid unnecessary locking when issuing I/O.

For example, if ufshcd_change_power_mode() gets error and leads to ufshcd_hba_exit() to release resources of the host, future shutdown flow may hang the system since the host register will be accessed in unpowered state. To solve this issue, simply add checking to skip shutdown for above kind of situation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The qla2xxx driver had this issue as well when the newer array firmware returned the retry_delay_timer in the fcp_rsp. The bnx2fc is not handling the masking of the scope bits either so the retry_delay_timestamp value lands up being a large value added to the timer timestamp delaying I/O for up to 27 Minutes. This patch adds similar code to handle this to the bnx2fc driver to avoid the huge delay.

Before internal task abort returned, reset begins, and it will check whether SAS_PHY_UNUSED is set, if not, it will call hisi_sas_init_device(), but at that time domain_device may already be freed or part of it is freed, so it may referenece null pointer in hisi_sas_init_device(). It may occur as follows: thread0 thread1 hisi_sas_dev_gone() check whether in RESET(no) internal task abort reset prep soft_reset ... (part of reset_done) internal task abort failed release resource anyway clear_itct device->lldd_dev=NULL hisi_sas_reset_init_all_device check sas_dev->dev_type is SAS_PHY_UNUSED and !device set dev_type SAS_PHY_UNUSED sas_free_device hisi_sas_init_device ... Semaphore hisi_hba.sema is used to sync the processes of device gone and host reset. To solve the issue, expand the scope that semaphore protects and let them never occur together. And also some places will check whether domain_device is NULL to judge whether the device is gone. So when device gone, need to clear sas_dev->sas_device.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The event handler calls scsi_scan_host() when events are missed, which will hotplug new LUNs. However, this function won't remove any unplugged LUNs. The result is that hotunplug doesn't work properly when the number of unplugged LUNs exceeds the event queue size (currently 8). Scan existing LUNs when events are missed to check if they are still present. If not, remove them.

Users have reported storage responding to such commands with INVALID FIELD IN CDB. Code before commit 327825574132 was not affected, as it called blk_rq_set_block_pc(). Fix this by zeroing out the cdb first. Identified & fix proposed by HPE.
