Martin K. Petersen af55ff675a [SCSI] sd: Support for SCSI disk (SBC) Data Integrity Field
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.

Brian King 072b91f9c6 [SCSI] ibmvfc: IBM Power Virtual Fibre Channel Adapter Client Driver
This patch adds a new device driver to support the Virtual Fibre Channel
interface on IBM Power based servers. The Virtual I/O Server on IBM Power
servers utilizes N-Port ID Virtualization to export a Virtual Fibre Channel
adapter to the client. This driver is the client device driver.

Chandra Seetharaman a6a8d9f87e [SCSI] scsi_dh: add infrastructure for SCSI Device Handlers
Some of the storage devices (that can be accessed through multiple paths),
do need some special handling for
	1. Activating the passive path of the storage access.
	2. Decode and handle the special sense codes returned by the devices.
	3. Handle the I/Os being sent to the passive path, especially
           during the device probe time.
when accessed through multiple paths.

As of today this special device handling is done at the dm-multipath
layer using dm-handlers. That works well for (1); for (2) to be handled
at dm layer, scsi sense information need to be exported from SCSI to dm-layer,
which is not very attractive; (3) cannot be done at all at the dm layer.

Device handler has been moved to SCSI mainly to handle (2) and (3) properly.

Finn Thain 6fe07aaffb [SCSI] m68k: new mac_esp scsi driver
Replace the mac_esp driver with a new one based on the esp_scsi core.

For esp_scsi: add support for sync transfers for the PIO mode, add a new
esp_driver_ops method to get the maximum dma transfer size (like the old
NCR53C9x driver), and some cleanups.

James Bottomley 9927c68864 [SCSI] ses: add new Enclosure ULD
This adds support to SCSI for enclosure services devices. It also makes
use of the enclosure services added in an earlier patch to display the
enclosure topology in sysfs.

At the moment, the enclosures are SAS specific, but if anyone actually
has a non-SAS enclosure that follows the SES-2 standard, we can add that
as well.

On my Vitesse based system, the enclosures show up like this:

sparkweed:~# ls -l /sys/class/enclosure/0\:0\:1\:0/
total 0
-r--r--r-- 1 root root 4096 2008-02-03 15:44 components

--w------- 1 root root 4096 2008-02-03 15:44 uevent

And the individual occupied slots like this:

sparkweed:~# ls -l /sys/class/enclosure/0\:0\:1\:0/SLOT\ 001/
total 0
-rw-r--r-- 1 root root 4096 2008-02-03 15:45 active

--w------- 1 root root 4096 2008-02-03 15:45 uevent

You can flash the various blinky lights by echoing to the fault and locate files.

>From the device's point of view, you can see it has an enclosure like this:

sparkweed:~# ls /sys/class/scsi_disk/0\:0\:0\:0/device/

enclosure_component:SLOT 001  model          scsi_generic:sg0
evt_media_change              power          scsi_level

Note the enclosure_component:SLOT 001 which shows where in the enclosure
this device fits.

The astute will notice that I'm using SCSI VPD Inquiries to identify the
devices.  This, unfortunately, won't work for SATA devices unless we do
some really nasty hacking about on the SAT because the only think that
knows the SAS addresses for SATA devices is libsas, not libata where the
SAT resides.

David S. Miller cd9ad58d40 [SCSI] SUNESP: Complete driver rewrite to version 2.0
Major features:

1) Tagged queuing support.
2) Will properly negotiate for synchronous transfers even on
   devices that reject the wide negotiation message, such as
   CDROMs
3) Significantly lower kernel stack usage in interrupt
   handler path by elimination of function vector arrays,
   replaced by a top-level switch statement state machine.
4) Uses generic scsi infrastructure as much as possible to
   avoid code duplication.
5) Automatic request of sense data in response to CHECK_CONDITION
6) Portable to other platforms using ESP such as DEC and Sun3
   systems.

James Bottomley 840c2835a1 [SCSI] make scsi_wait_scan always modular
Currently scsi_wait_scan is only built modular if SCSI is modular.
However, it's perfectly possible for a built in SCSI still to have
modular drivers and thus need scsi_wait_scan as a module.  Therefore,
scsi_wait_scan should always be built as a module (unless the kernel
doesn't support modules).

Matthew Wilcox 3e082a910d [SCSI] Add ability to scan scsi busses asynchronously
Since it often takes around 20-30 seconds to scan a scsi bus, it's
highly advantageous to do this in parallel with other things.  The bulk
of this patch is ensuring that devices don't change numbering, and that
all devices are discovered prior to trying to start init.  For those
who build SCSI as modules, there's a new scsi_wait_scan module that will
ensure all bus scans are finished.

This patch only handles drivers which call scsi_scan_host.  Fibre Channel,
SAS, SATA, USB and Firewire all need additional work.

James Smart 84314fd474 [SCSI] SCSI and FC Transport: add netlink support for posting of transport events
This patch formally adds support for the posting of FC events via netlink.
It is a followup to the original RFC at:
  http://marc.theaimsgroup.com/?l=linux-scsi&m=114530667923464&w=2
and the initial posting at:
  http://marc.theaimsgroup.com/?l=linux-scsi&m=115507374832500&w=2

The patch has been updated to optimize the send path, per the discussions
in the initial posting.

Per discussions at the Storage Summit and at OLS, we are to use netlink for
async events from transports. Also per discussions, to avoid a netlink
protocol per transport, I've create a single NETLINK_SCSITRANSPORT protocol,
which can then be used by all transports.

This patch:
- Creates new files scsi_netlink.c and scsi_netlink.h, which contains the
  single and shared definitions for the SCSI Transport. It is tied into the
  base SCSI subsystem intialization.
  Contains a single interface routine, scsi_send_transport_event(), for a
  transport to send an event (via multicast to a protocol specific group).
- Creates a new scsi_netlink_fc.h file, which contains the FC netlink event
  messages
- Adds 3 new routines to the fc transport:
   fc_get_event_number() -  to get a FC event #
   fc_host_post_event()  -  to send a simple FC event (32 bits of data)
   fc_host_post_vendor_event() - to send a Vendor unique event, with
                                 arbitrary amounts of data.

   Note: the separation of event number allows for a LLD to send a standard
     event, followed by vendor-specific data for the event.

Note: This patch assumes 2 prior fc transport patches have been installed:
   http://marc.theaimsgroup.com/?l=linux-scsi&m=115555807316329&w=2
   http://marc.theaimsgroup.com/?l=linux-scsi&m=115581614930261&w=2

   Sorry - next time I'll do something like making these individual
   patches of the same posting when I know they'll be posted closely
   together.

Mike Christie 7996a778ff [SCSI] iscsi: add libiscsi
There is a lot of code duplcited between iscsi_tcp
and the upcoming iscsi_iser driver. This patch puts
the duplicated code in a lib. There is more code
to move around but this takes care of the
basics. For iscsi_offload if they use the lib we will
probably move some things around. For example in the
queuecommand we will not assume that the LLD wants
to do queue_work, but it is better to handle that
later when we know for sure what iscsi_offload looks
like (we could probably do this for iscsi_iser though to).

Ideally I would like to get the iscsi_transports modules
to a place where all they really have to do is put data
on the wire, but how to do that will hopefully be more clear
when we see other modules like iscsi_offload. Or maybe
iscsi_offload will not use the lib and it will just be
iscsi_iser and iscsi_tcp and maybe the iscsi_tcp_tgt if that
is allowed in mainline.
