2011-08-27[SCSI] bnx2fc: Prevent creating of NPIV port with duplicate WWNBhanu Prakash Gollapudi
This patch adds a validation step before allowing creation of a new NPIV port. It checks whether the WWPN passed for the new NPIV port to be created is unique for the given physical port.

2011-08-27[SCSI] bnx2fc: Fix NULL pointer deref during arm_cq.Bhanu Prakash Gollapudi
There exists a race condition between CQ doorbell unmap and IO completion path that arms the CQ which causes a NULL dereference. Protect the ctx_base with cq_lock to avoid this. Also, wait for the CQ doorbell to be successfully mapped before arming the CQ. Also, do not count uncolicited CQ completions for free_sqes.

2011-08-27[SCSI] bnx2fc: IO errors when receiving unsolicited LOGOBhanu Prakash Gollapudi
During the unsolicited LOGO processing, the session is uploaded and offloaded after the relogin is complete. In between any new IOs are errored back as the upload completion flag is set. Upon exhausting the retry count, the application fails the IOs. Return target busy for all the cases when session is not ready.

2011-08-27[SCSI] bnx2fc: Do not attempt destroying NPIV port twiceBhanu Prakash Gollapudi
When NPIV ports are created/deleted rapidly there is a race condition between bnx2fc_vport_destroy() from sysfs and bnx2fc_flogi_resp(), which could try to delete the NPIV port from the list twice.

2011-08-27[SCSI] qla2xxx: T10 DIF - Fix incorrect error reporting.Arun Easi
This fix: - Disables app tag peeking; correct tag check will be added when the SCSI API is available. - Always derive ref_tag from scsi_get_lba() - Removes incorrect swap of FCP_LUN in FCP_CMND - Moves app-tag error check before ref-tag check. The reason being, currently there is no interface in SCSI to retrieve the app-tag for protection I/Os, so driver puts zero for app-tag in the firmware interface, but requests not to validate it, but when a ref-tag error is detected by firmware, it would put expected/actual tags for all the protection tags (guard/app/ref). As driver checks for app tag error first, a ref-tag error is incorrectly flagged as app-tag error. - Convert HBA specific checks to capability based.

2011-08-26[SCSI] hpsa: fix physical device lun and target numbering problemStephen M. Cameron
If a physical device exposed to the OS by hpsa is replaced (e.g. one hot plug tape drive is replaced by another, or a tape drive is placed into "OBDR" mode in which it acts like a CD-ROM device) and a rescan is initiated, the replaced device will be added to the SCSI midlayer with target and lun numbers set to -1. After that, a panic is likely to ensue. When a physical device is replaced, the lun and target number should be preserved. Signed-off-by: Stephen M.

2011-08-23[SCSI] isci: dynamic interrupt coalescingDan Williams
Hardware allows both an outstanding number commands and a timeout value (whichever occurs first) as a gate to the next interrupt generation. This scheme at completion time looks at the remaining number of outstanding tasks and sets the timeout to maximize small transaction operation. If transactions are large (take more than a few 10s of microseconds to complete) then performance is not interrupt processing bound, so the small timeouts this scheme generates are overridden by the time it takes for a completion to arrive.

2011-08-23[SCSI] isci: fix 32-bit operation when CONFIG_HIGHMEM64G=nDan Williams
The unsolicited frame control infrastructure requires a table of dma addresses for the hardware to lookup the frame buffer location by an index. The hardware expects the elements of this table to be 64-bit quantities, so we cannot reference these elements as dma_addr_t. All unsolicited frame protocols are affected, particularly SATA-PIO and SMP which prevented direct-attached SATA drives and expander-attached drives to not be discovered.
