* [SCSI] ibmvfc: Reduce unnecessary log noiseBrian King2008-07-26

* [SCSI] sym53c8xx: free luntbl in sym_hcb_freeMike Anderson2008-07-26
| | | | | | | | | | | | This patch frees the luntbl dma area in sym_hcb_free if allocated. Since the luntbl is part of a larger dma coherent area not freeing the luntbl kept a 64k dma coherent area previous allocated through dma_alloc_coherent allocated. This prevented a DLPAR remove IO operation from completing successfully.

* [SCSI] scsi_scan.c: Release mutex in error handling codeJulia Lawall2008-07-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mutex is released on a successful return, so it would seem that it should be released on an error return as well. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression l; @@ mutex_lock(l); ... when != mutex_unlock(l) when any when strict ( if (...) { ... when != mutex_unlock(l) + mutex_unlock(l); return ...; } | mutex_unlock(l); ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
* [SCSI] scsi_eh_prep_cmnd should save scmd->underflowAlan Stern2008-07-26
| | | | | | | | | | | | | This patch (as1116) fixes a bug in scsi_eh_prep_cmnd() and scsi_eh_restore_cmnd(). These routines are supposed to save any values they change and restore them later, but someone forgot to save & restore scmd->underflow. This fixes part of the problem reported in Bugzilla #9638.

* [SCSI] sd: Support for SCSI disk (SBC) Data Integrity FieldMartin K. Petersen2008-07-26
| | | | | | | | | | | | | | | | | | | | | | Support for controllers and disks that implement DIF protection information: - During command preparation the RDPROTECT/WRPROTECT must be set correctly if the target has DIF enabled. - READ(6) and WRITE(6) are not supported when DIF is on. - The controller must be told how to handle the I/O via the protection operation field in scsi_cmnd. - Refactor the I/O completion code that extracts failed LBA from the returned sense data and handle DIF failures correctly. - sd_dif.c implements the functions required to prepare and complete requests with protection information attached.

* [SCSI] sd: Identify DIF protection type and application tag ownershipMartin K. Petersen2008-07-26
| | | | | | | | | | | | | | If a disk is formatted with protection information (Inquiry bit PROTECT=1) it is required to support Read Capacity(16). Force use of the 16-bit command in this case and extract the P_TYPE field which indicates whether the disk is formatted using DIF Type 1, 2 or 3. The ATO (App Tag Own) bit in the Control Mode Page indicates whether the storage device or the initiator own the contents of the DIF application tag. Signed-off-by: Martin K.

* [SCSI] Command protection operationMartin K. Petersen2008-07-26
| | | | | | | | | | | | | | | | | | | | | | | | | Controllers that support DMA of protection information must be told explicitly how to handle the I/O. The controller has no knowledge of the protection capabilities of the target device so this information must be passed in the scsi_cmnd. - The protection operation tells the HBA whether to generate, strip or verify protection information. - The protection type tells the HBA which layout the target is formatted with. This is necessary because the controller must be able to correctly interpret the included protection information in order to verify it. - When a scsi_cmnd is reused for error handling the protection operation must be cleared and saved while error handling is in progress. - prot_op and prot_type are placed in an existing hole in scsi_cmnd and don't cause the structure to grow.

* [SCSI] Host protection capabilitiesMartin K. Petersen2008-07-26
| | | | | | | | | | | | | | | | Controllers that support protection information must indicate this to the SCSI midlayer so that the ULD can prepare scsi_cmnds accordingly. This patch implements a host mask and various types of protection: - DIF Type 1-3 (between HBA and disk) - DIX Type 0-3 (between OS and HBA) The patch also allows the HBA to set the guard type to something different than the T10-mandated CRC.

* [SCSI] fix shared tag map tag allocationMike Christie2008-07-26
| | | | | | | | | | | | | | | | | | | When drivers use a shared tag map we can end up with more requests than tags, because the tag map is shost->can_queue tags and there can be sdevs * sdev->queue_depth requests. In scsi_request_fn if tag allocation fails we just drop down to just dequeueing the tag without a tag. The problem is that drivers using the shared tag map rely on a valid tag always being set, because it will use the tag number to lookup commands later. This patch has us check if we got a valid tag when the host lock is held right before we check if the host queue is ready. We do the check here because to allocate the tag we need the q lock, but if the tag is bad we want to add the device/q onto the starved list which requires the host lock.

* [SCSI] fix shared tag map setupMike Christie2008-07-26
| | | | | | | | | | | | | | | | | | Currently qla4xxx and stex pass in their can_queue values into scsi_activate_tcq because they wanted the tag map that large. The problem with this is that it ends up also setting the queue depth to that large value. All we want to do this in this case is set the device queue depth and the other device settings. We do not need to touch the tag map sizing because the drivers had setup that map according to their can_queue limits when the shared map was created. The scsi mid layer in request_fn will then handle the case where we have more requests than available tags when it checks the host queue ready function.
