When T10 PI is enabled on a backing device for the iblock backstore, the PI SGL for the entire command is attached to the first bio only. This works fine if the command is covered by a single bio, but can result in ref tag errors in the client for the other bios in a multi-bio command, e.g. [ 47.631236] sda: ref tag error at location 2048 (rcvd 0) [ 47.637658] sda: ref tag error at location 4096 (rcvd 0) [ 47.644228] sda: ref tag error at location 6144 (rcvd 0) The command will be split into multiple bios if the number of data SG elements exceeds BIO_MAX_PAGES (see iblock_get_bio()). The bios may later be split again in the block layer on the host after iblock_submit_bios(), depending on the queue limits of the backing device. The block and SCSI layers will pass through the whole PI SGL down to the LLDD however that first bio is split up, but the LLDD may only use the portion that corresponds to the data length (depends on the LLDD, tested with scsi_debug). Split the PI SGL across the bios in the command, so each bio's bio_integrity_payload contains the protection information for the data in the bio. Use an sg_mapping_iter to keep track of where we are in PI SGL, so we know where to start with the next bio. Signed-off-by:

Error paths in ufshcd_init() ufshcd_hba_exit() killed clk_scaling workqueue when the workqueue is actually created quite late in ufshcd_init(). So, we end up getting NULL pointer dereference in such error paths. Fix this by moving clk_scaling initialization and kill codes to two separate methods, and call them at required places.

This patch adds the ability to read firmware logs from the adapter. The driver registers a buffer with the adapter that is then written to by the adapter. The adapter posts CQEs to indicate content updates in the buffer. While the adapter is writing to the buffer in a circular fashion, an application will poll the driver to read the next amount of log data from the buffer. Driver log buffer size is configurable via the ras_fwlog_buffsize sysfs attribute. Verbosity to be used by firmware when logging to host memory is controlled through the ras_fwlog_level attribute. The ras_fwlog_func attribute enables or disables loggy by firmware. Signed-off-by:

Currently, on each io completion, the stats update routine indiscriminately holds a lock. While holding the adapter-wide lock, checks are made to check whether status are being tracked. When disabled (the default), the locking wasted a lot of cycles. Check for stats enablement before taking the lock. Signed-off-by:

During attachment, the driver writes the EQ doorbell to disable potential interrupts from an EQ. The current EQ doorbell format used for clearing the interrupt is incorrect and uses an if_type=2 format, making the operation act on the wrong EQ. Correct the code to use the proper if_type=6 EQ doorbell format. Signed-off-by:

When taking the board offline while performing i/o, unsafe locking errors occurred and irq level isn't properly managed. In lpfc_sli_hba_down, spin_lock_irqsave(&phba->hbalock, flags) does not disable softirqs raised from timer expiry. It is possible that a softirq is raised from the lpfc_els_retry_delay routine and recursively requests the same phba->hbalock spinlock causing deadlock. Address the deadlocks by creating a new port_list lock. The softirq behavior can then be managed a level deeper into the calling sequences. Signed-off-by:

When running an mds diagnostic that passes frames with the switch, soft lockups are detected. The driver is in a CQE processing loop and has sufficient amount of traffic that it never exits the ring processing routine, thus the "lockup". Cap the number of elements in the work processing routine to 64 elements. This ensures that the cpu will be given up and the handler reschedule to process additional items. Signed-off-by:

On io completion, the driver is taking an adapter wide lock and nulling the scsi command back pointer. The nulling of the back pointer is to signify the io was completed and the scsi_done() routine was called. However, the routine makes no check to see if the abort routine had done the same thing and possibly nulled the pointer. Thus it may doubly-complete the io. Make the following mods: - Check to make sure forward progress (call scsi_done()) only happens if the command pointer was non-null. - As the taking of the lock, which is adapter wide, is very costly on a system under load, null the pointer using an xchg operation rather than under lock.

When nvme is enabled, change the default for two parameters: sg_seg_cnt - raise the per-io sg list size so that 1MB ios are supported (based on a 4k buffer per element). iocb_cnt - raise the number of buffers used for things like NVME LS request/responses to allow more concurrent requests to for larger nvme configs.

The driver allocates a sg list per io struture based on a fixed maximum size. When it registers with the protocol transports and indicates the max sg list size it supports, the driver manipulates the fixed value to report a lesser amount so that it has reserved space for sg elements that are used for DIF. The driver initialization path sets the cfg_sg_seg_cnt field to the manipulated value for scsi. NVME initialization ran afterward and capped it's maximum by the manipulated value for SCSI. This erroneously made NVME report the SCSI-reduce-for-DIF value that reduced the max io size for nvme and wasted sg elements. Rework the driver so that cfg_sg_seg_cnt becomes the overall maximum size and allow the max size to be tunable. A separate (new) scsi sg count is then setup with the scsi-modified reduced value. NVME then initializes based off the overall maximum. Signed-off-by:

Driver only sends NVME PRLI to a device that also supports FCP. This resuls in remote ports that don't have fc_remote_ports created for them. The driver is clearing the nlp_fc4_type for a ndlp at the wrong time. Fix by moving the nlp_fc4_type clearing to the discovery engine in the DEVICE_RECOVERY state. Also ensure that rport registration is done for all nlp_fc4_types. Signed-off-by:
