When the lldd is processing the complete sas task in interrupt and set the task stat as SAS_TASK_STATE_DONE, the smp timeout timer is able to be triggered at the same time. And smp_task_timedout() will complete the task wheter the SAS_TASK_STATE_DONE is set or not. Then the sas task may freed before lldd end the interrupt process. Thus a use-after-free will happen. Fix this by calling the complete() only when SAS_TASK_STATE_DONE is not set. And remove the check of the return value of the del_timer(). Once the LLDD sets DONE, it must call task->done(), which will call smp_task_done()->complete() and the task will be completed and freed correctly.

When ata device IDENTIFY failed, the ata device status is ATA_DEV_UNKNOWN. The libata reported like: [113518.620433] ata5.00: qc timeout (cmd 0xec) [113518.653646] ata5.00: failed to IDENTIFY (I/O error, err_mask=0x4) But libsas verifies the device status by ata_dev_disabled(), which skipped ATA_DEV_UNKNOWN. This will make libsas think the ata device probing succeed the device cannot be actually brought up. And even the new bcast of this device will be considered as flutter and will not probe this device again. Change ata_dev_disabled() to !ata_dev_enabled() so that libsas can deal with this if the ata device probe failed. New bcasts can let us try to probe the device again and bring it up if it is fine to IDENTIFY.

If we went into sas_rediscover_dev() the attached_sas_addr was already insured not to be zero. So it's unnecessary to check if the attached_sas_addr is zero. And although if the sas address is not changed, we always have to unregister the old device when we are going to register a new one. We cannot just leave the device there and bring up the new.

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.

When the firmware is not responding, execution of kexec boot causes a system hang. When firmware assertion happened, driver get notified with interrupt vector updated in MPI configuration table. Then, the driver will read scratchpad register and set controller_fatal_error flag to true.
