When using this driver on a Blizzard 1260, there were failures whenever DMA transfers from the SCSI bus to memory of 65535 bytes were followed by a DMA transfer of 1 byte. This caused the byte at offset 65535 to be overwritten with 0xff. The Blizzard hardware can't handle single byte DMA transfers. Besides this issue, limiting the DMA length to something that is not a multiple of the page size is very inefficient on most file systems. It seems this limit was chosen because the DMA transfer counter of the ESP by default is 16 bits wide, thus limiting the length to 65535 bytes. However, the value 0 means 65536 bytes, which is handled by the ESP and the Blizzard just fine. It is also the default maximum used by esp_scsi when drivers don't provide their own dma_length_limit() function. The limit of 65536 bytes can be used by all boards except the Fastlane. The old driver used a limit of 65532 bytes (0xfffc), which is reintroduced in this patch. Fixes: b7ded0e8 ("scsi: zorro_esp: Limit DMA transfers to 65535 bytes") Link: https://lore.kernel.org/r/20191112175523.23145-1-jongk@linux-m68k.orgSigned-off-by:

In function __ufshcd_query_descriptor(), in the event of an error happening, we directly goto out_unlock and forget to invaliate hba->dev_cmd.query.descriptor pointer. This results in this pointer still valid in ufshcd_copy_query_response() for other query requests which go through ufshcd_exec_raw_upiu_cmd(). This will cause __memcpy() crash and system hangs.

Currently we call function hisi_sas_debugfs_exit() to remove debugfs_dir before freeing interrupt irqs and destroying workqueue in the driver remove path. If a dump is triggered before function hisi_sas_debugfs_exit() but debugfs_work may be called after it, so it may refer to already removed debugfs_dir which will cause NULL pointer dereference. To avoid it, put function hisi_sas_debugfs_exit() after free_irqs and destroy workqueue when removing hisi_sas driver.

Avoid an uninitialized value (0) for ha->fc4_type_priority being falsely interpreted as NVMe priority. Not strictly needed any more after the previous patch, but makes the fc4_type_priority handling more explicit. Link: https://lore.kernel.org/r/20191107224839.32417-3-martin.wilck@suse.comTested-by:

ha->fc4_type_priority is currently initialized only in qla81xx_nvram_config(). That makes it default to NVMe for other adapters. Fix it. Fixes: 84ed362a ("scsi: qla2xxx: Dual FCP-NVMe target port support") Link: https://lore.kernel.org/r/20191107224839.32417-2-martin.wilck@suse.comTested-by:

On heavy loads, a memory leak of the srb_t structure is observed. This would make the qla2xxx_srbs cache gobble up memory.

Current code assumes abort will remove the original command from the active list where scsi_done will not be called. Instead, the eh_abort thread will do the scsi_done. That is not the case. Instead, we have a double scsi_done calls triggering use after free. Abort will tell FW to release the command from FW possesion. The original command will return to ULP with error in its normal fashion via scsi_done. eh_abort path would wait for the original command completion before returning. eh_abort path will not perform the scsi_done call.
