[SCSI] bfa: fix strncpy() limiter in bfad_start_ops()

2013-01-30T00:54:54+00:00

The closing parenthesis is in the wrong place so it takes the sizeof a
pointer instead of the sizeof the buffer minus one.

Drivers: scsi: remove __dev* attributes.

2013-01-03T23:57:01+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

[SCSI] bfa: Firmware image naming convention update

2012-10-07T10:28:06+00:00

- Modified the firmware naming convention to contain the
  firmware image version (3.1.0.0).
- The new convention is -.bin
- The change will enforce loading only compatible firmware with this driver
  and also avoid over-writing the old firmware image in-order to load new
  version driver as the firmware names used to be the same.

[SCSI] bfa: Add support for max target ports discovery

2012-09-24T08:10:57+00:00

- Changes to avoid discovering NPIV port as remote port by the other
  NPIV ports created on same physical port when all the NPIV ports are
  part of the same zone in a fabric.
- Provided mechanism to support maximum number of target ports for a
  given initiator port (physical port + NPIV ports) irrespective of the
  way in which the initiator and target ports are zoned in the fabric.
- Introduced module_parameter max_rport_logins to restrict number of
  remote ports discovery which includes target and initiator remote ports.

[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: Fix to defer vport delete handler invocation till firmware logo response.

2012-04-25T08:58:31+00:00

Made changes to avoid queuing the vport delete work to IM driver
work queue in the bfa_fcb_lport_delete() - since at this stage we
are not completely done with using the vport structure as we are
still waiting for the LOGO response from the fw in online state or
just doing some cleanup. Since queuing up the vport delete work at
this stage will result in the FC transport layer to clean up the vport
before we get the response from firmware.
Made changes to queue the port delete work to the IM driver work queue -
from the bfa_fcs_vport_free() function since at this state we are done
with using the vport data structure and the FCS state machine is completely
cleaned up.

[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.
