->queuecommand must return either 0, or one of the SCSI_MLQUEUE_* return values. Non-transient errors are indicated by setting cmd->result before calling ->scsi_done and returning 0. Fix libsas to adhere to this calling convention. Note that the DID_ERROR for returns from the low-level driver might not be correct for all cases, but it's the best we can do with the current layering in libsas. I also suspect that the pre-existing handling of -SAS_QUEUE_FULL should really be SCSI_MLQUEUE_HOST_BUSY, but I'll leave that for a separate change. Signed-off-by:

sd_ioctl() still use printk() for log output. It should use sd_printk() instead of printk(), as well as other sd_*. All SCSI messages should output via s*_printk() instead of printk(). Signed-off-by:

This patch allows the user to set an "alias" of the disk via sysfs interface. This patch only adds a new attribute "alias" in gendisk structure. To show the alias instead of the device name in kernel messages, we need to revise printk messages and use alias_name() in them. Example: (current) printk("disk name is %s\n", disk->disk_name); (new) printk("disk name is %s\n", alias_name(disk)); Users can use alphabets, numbers, '-' and '_' in "alias" attribute. A disk can have an "alias" which length is up to 255 bytes. This attribute is write-once. Suggested-by:James Bottomley <James.Bottomley@HansenPartnership.com> Suggested-by:

The problem is that if we are doing a scsi scan then the device goes into recovery then we will wait for the recovery to complete. It waits because scsi-ml will send inquiries or report luns and the queueing code will have been blocked due to the host not being ready. However, if we are in recovery and then a scan is started the scan will silently fail and some devices will not be added. It is easy to hit the problem where devices do not show up with FC where we are doing tests that disrupt the target controllers. When the controller is disruprted (reboot, or setting firmware, etc), and we cause the dev loss tmo to fire then devices will be removed Then when the problem has been fixed, the rport will be scanned and devices should be added back. But if we cause another disruption before scanning has started then devices will not get added back. If the problem is not started until the scan is started then the devices will be added back. This patch fixes that problem by not failing scans when the host is in recovery. We will let scsi-ml send the IO and let the queueing and scsi error handling deal with it like is done if we went into recovery while scanning. For recovery cases where the host is being torn down then with the patch we will still fail the scan since there is not point in scanning. Signed-off-by:

Fix SYSFS interface issues. - In the lpfc_sli4_pdev_status_reg_wait() routine, after initial 100ms delay following write to PHYSDEV_CONTROL register for the firmware reaction, check the RN bit and ERR bit of the SLIPORT_STATUS register. If none of them became 1, the previous PHYSDEV_CONTROL register should be considered failed due to lack of privilege and error for no permission should be returned immediately without getting into the wait for RDY bits on the SLIPORT_STATUS register. - Remove the driver check on dev->is_physfn before proceed to perform the PHYSDEV_CONTROL register write, and let the PCI function's privilege setting and driver handling of PHYSDEV_CONTROL register write failure to handle the reset-ability through the SLI port. - Added key to ctlreg_write to prevent unauthorized or unexpected write to the control register. - Change return to EACCES for sysfs access that are failed because hba_reset is disabled.

Fix HBA initialization issues - Swap all values that come from the firmware image on little endian systems. Created a new bf_get_be macro that does the same as the bf_get_le macro but for big endian data instead of little endian data. - Moved the incrementing of temp_offset after the copy fixed the write object loop to use temp_offset to figure out where the end of the image is instead of offset. - Added the necessary codes for properly bringing the driver instance offline and then trying to bring the port back online with the PCI function IP reset. If it fails to bring the SLI port back online, it will fall through to bringing the SLI port to HBA error offline. - Add a call in the probe_one_s3 and probe_one_s4 routines to get the Modeldesc - Change OCe50100 to OCe15100 - Made the error log also include the PCI BAR bitmap returned from kernel call pci_select_bars().

Fix issues pertaining to SCSI/FC protocol. - Allow frames destined to 0xFFFFFE to be processed by the driver by matching that DID with the physical port. - Call lpfc_sli_issue_iocb with context1 set to ndlp - In echo command accept function, adjust memcpy to limit memcpy to 1K - Set LPFC_SLI3_BG_ENABLED properly upon completion. - Skip the INIT_VFI call in lpfc_register_fcf if the FCF is already registered and go immediately to initial flogi. - use "status" variable instead of "ret" variable to hold the return of the fc_block_scsi_eh.

Fix be2iscsi driver to use a separate pointer for each irq action->name field and avoid display corruption in /proc/interrupts. The be2iscsi driver was using a single static array in a function for the irq action->name field. This results in garbage output from /proc/interrupts The pointer for action->name is garbage and scribbles the output on the screen. This patch fixes the problem: 156: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 PCI-MSI-X beiscsi_msix_0017 This patch is based on Prarit's patch here: http://www.spinics.net/lists/linux-scsi/msg52325.html but I have fixed up the failure paths and removed redundant check for !i suggested by Eike.

The Marvell Universal Message Interface (UMI) defines a messaging interface between host and Marvell products (Plato, for example). It considers situations of limited system resource and optimized system performance. UMI driver translates host request to message and sends message to FW via UMI, FW receives message and processes it, then sends response to UMI driver. FW generates an interrupt when it needs to send information or response to UMI driver Signed-off-by:

Some CD-ROMs fail to report a media change correctly. The specific one for this patch simply fails to respond to commands, then gives a UNIT ATTENTION after being reset which returns ASC/ASCQ 28/00. This is out of spec behaviour, but add a check in the eat CC/UA on reset path to catch this case so the CD-ROM will function somewhat properly.
