[SCSI] bfa: set correct command return code

2014-03-15T17:19:17+00:00

For various error conditions the bfa driver just returns
'DID_ERROR', which carries no information at all about the
actual source of error.
This patch updates the error handling to return a correct
error code, depending on the type of error occurred.

[SCSI] bfa: Add PowerPC support and enable PCIE AER handling.

2012-09-24T08:10:56+00:00

- Added few missing endian swap changes to support BFA on PowerPC.
- Added PCIE AER support to BFA:
  a) Implemented the PCI error handler entry points.
  b) Made changes to FCS state machine to handle STOP event from the
	 PCI error detected entry point.
  c) Made changes to the IO Controller state machine to handle SUSPEND
     event from the PCI error detected entry point.
  d) Made changes to restart the BFA operations on a slot_reset completion.

[SCSI] bfa: dereferencing freed memory in bfad_im_probe()

2012-07-20T07:58:37+00:00

If bfad_thread_workq(bfad) was not BFA_STATUS_OK then we freed "im"
and then dereferenced it.

I did a little clean up because it seemed nicer to return directly
instead of doing a superfluous goto.  I looked at other functions in
this file and it seems like returning directly is standard.

[SCSI] bfa: Implement LUN Masking feature using the SCSI Slave Callouts.

2012-01-10T23:01:24+00:00

This patch re-implements LUN Masking feature using SCSI Slave Callouts.  With
the new design in the slave_alloc entry point; for each new LUN discovered we
check with our internal LUN Masking config whether to expose or to mask this
particular LUN. We return -ENXIO (No such device or address) from slave_alloc
for the LUNs we don't want to be exposed.  We also notify the SCSI mid-layer
to do a sequential LUN scan rather than REPORT_LUNS based scan if LUN masking
is enabled on our HBA port, since a -ENXIO from any LUN in REPORT_LUNS based
scan translates to a scan abort.  This patch also handles the dynamic lun
masking config change from enable to disable or vice-versa by resetting
sdev_bflags of LUN 0 appropriately.

scsi: Add export.h for EXPORT_SYMBOL/THIS_MODULE as required

For the basic SCSI infrastructure files that are exporting symbols
but not modules themselves, add in the basic export.h header file
to allow the exports.
