Anil Ravindranath df30e50596 [SCSI] pmcraid: remove duplicate struct member
sense_buffer is both a direct member of struct pmcraid_cmd as well as
an indirect one via an anonymous union and struct.  Fix this clash by
eliminating the direct member in favour of the anonymous struct/union
one.  The name duplication apparently isn't noticed by gcc versions
earlier than 4.4

Mike Christie a1e0063d0c [SCSI] qla4xxx: Fix cmd check in qla4xxx_cmd_wait
If the command has timedout then the block layer has called
blk_mark_rq_complete. If qla4xxx_cmd_wait is then called
from qla4xxx_eh_host_reset, we will always fail, because if
the driver calls scsi_done then the the block layer will fail
at blk_complete_request's blk_mark_rq_complete call instead of
calling the normal completion path including the function,
blk_queue_end_tag, which releases the tag.

If fw didn't raise the interrupt with the fw state change to driver
and fw goes to failure state, driver Will check the FW state in
driver's timeout routine and issue the reset if need.  Driver will do
the OCR upto three times until kill adapter.  Also driver will issue
OCR before driver kill adapter even if fw in operational state.

Boaz Harrosh 6dd1d8a795 [SCSI] libosd: write/read_sg_kern API
This is a trivial addition to the SG API that can receive kernel
pointers. It is only used by the out-of-tree test module. So
it's immediate need is questionable. For maintenance ease it might
just get in, as it's very small.

John.
do you need this in the Kernel, or is it only for osd_ktest.ko?

Boaz Harrosh e96e72c45a [SCSI] libosd: Support for scatter gather write/read commands
This patch adds the Scatter-Gather (sg) API to libosd.
Scatter-gather enables a write/read of multiple none-contiguous
areas of an object, in a single call. The extents may overlap
and/or be in any order.

The Scatter-Gather list is sent to the target in what is called
a "cdb continuation segment". This is yet another possible segment
in the osd-out-buffer. It is unlike all other segments in that it
sits before the actual "data" segment (which until now was always
first), and that it is signed by itself and not part of the data
buffer. This is because the cdb-continuation-segment is considered
a spill-over of the CDB data, and is therefor signed under
OSD_SEC_CAPKEY and higher.

TODO: A new osd_finalize_request_ex version should be supplied so
the @caps received on the network also contains a size parameter
and can be spilled over into the "cdb continuation segment".

Thanks to John Chandy <john.chandy@uconn.edu> for the original
code, and investigations. And the implementation of SG support
in the osd-target.

At osd_end_request first free the request that might
point to pages, then free these pages. In reverse order

Adapter Shutdown and Unregistration cleanup

- Correct the logic around hba shutdown. Prior to final reset, the
  driver must wait for all XRIs to return from the adapter. Added logic
  to poll, progressively slowing the poll rate as delay gets longer.
- Correct behavior around the rsvd1 field in UNREG_RPI_ALL mailbox
  completion and final rpi cleanup.
- Updated logic to move pending VPI registrations to their completion
  in cases where a CVL may be received while registration in progress.
- Added unreg all rpi mailbox command before unreg vpi.

James Smart a93ff37a8a [SCSI] lpfc 8.3.18: Add logic to detect last devloss timeout
Added driver logic to detect the last devloss timeout of remote nodes which
was still in use of FCF. At that point, the driver should set the last
in-use remote node devloss timeout flag if it was not already set and should
perform proper action on the in-use FCF and recover of FCF from firmware,
depending on the state the driver's FIP engine is in.

Find eligible FCF through FCF table rescan or the next new FCF event when
FCF table rescan turned out empty eligible FCF, and the successful flogi
into an FCF shall clear the HBA_DEVLOSS_TMO flag, indicating the successful
recovery from devloss timeout.

James Smart 5ac6b30383 [SCSI] lpfc 8.3.18: FC/FCoE Discovery fixes
FC/FCoE Discovery fixes:

- Call the lpfc_drain_txq only for SLI4 hba
- In lpfc_cmpl_els_fdisc, fix code path that does not free IOCB.
- Treated firmware matching FCF property with different index as error
- Propagate error returns from lpfc_issue_els_flogi()
- Refactored lpfc_unregister_unused_fcf() to create a post
  lpfc_dev_loss_tmo handler call for SLI-4 devices. Allows checking of
  fcf after last ndlp released so that fcf can be released if no longer
  in use.
- Replaced individual FCF_XXXX_DISC flag clearing in lieu of aggregate
  FCF_DISCOVERY flag upon succesful completion of flogi.
- Correct setting of altBbCredit value in sparams to correct issue with
  logins with remote loop-based devices.
