From: Douglas Gilbert <dougg@torque.net>

Subject: [SCSI] scsi_debug version 1.79

  - add 'virtual_gb' parameter to simulate large storage
    (by wrapping in dev_size_mb megabytes of actual ram)
  - add 'no_lun_0' parameter to skip lun 0 on each target
    (but still respond as required to INQUIRY + REPORT LUNS)
  - add well know lu support
  - add MODE SELECT commands support [pages: 0xa and 0x1c]
  - add LOG SENSE command support [pages: 0xd and 0x2f]
  - add READ CAPACITY (16) support
  - increase number of mode pages supported (to read),
    mainly transport specific (SAS) mode (sub)pages
  - add more VPD pages and extend others, including
    ATA information VPD page
  - START STOP UNIT now maintains a state machine
  - READ (16) and WRITE (16) cope with lbas larger
    than 32 bits (needed for the 'virtual_gb' parameter)
  - allow single command transfers up to 32 MB
  - more precise error (sense data) messages

Subject: [SCSI] ibmvscsi: treat busy and error conditions separately

This patch fixes a condition where ibmvscsi treats a transport error as a
"busy" condition, so no errors were returned to the scsi mid-layer.
In a RAID environment this means that I/O hung rather than failing
over.

Subject: [SCSI] megaraid_sas: zcr with fix

The patch adds support for a ZCR controller (Device ID : 0x413).

It also has a critical bug fix :

Disable controller interrupt before firing INIT cmd to FW.  Interrupt
is enabled after required initialization is over. This is done to
ensure that driver is ready to handle interrupts when it is generated
by the controller.

Subject: [SCSI] aic79xx: remove slave_destroy

Even with the latest fixes aic79xx still occasionally triggers the
BUG_ON in slave_destroy. Rather than trying to figure out the various
levels of interaction here I've decided to remove the callback altogether.

The primary reason for the slave_alloc / slave_destroy is to keep an
index of pointers to the sdevs associated with a given target.
However, by changing the arguments to the affected functions slightly
it's possible to avoid the use of that index entirely.
The only performance penalty we'll incur is in writing the
information for /proc/scsi/XXX, as we'll have to recurse over all
available sdevs to find the correct ones. But I doubt that reading
from /proc is in any way time-critical.

From 03aba2f79594ca94d159c8bab454de9bcc385b76 Mon Sep 17 00:00:00 2001
From: Luben Tuikov <ltuikov@yahoo.com>
Date: Fri, 23 Jun 2006 09:39:09 -0700
Subject: [SCSI] sd/scsi_lib simplify sd_rw_intr and scsi_io_completion

This patch simplifies "good_bytes" computation in sd_rw_intr().
sd: "good_bytes" computation is always done in terms of the resolution
of the device's medium, since after that it is the number of good bytes
we pass around and other layers/contexts (as opposed ot sd) can translate
that to their own resolution (block layer:512).  It also makes
scsi_io_completion() processing more straightforward, eliminating the
3rd argument to the function.

It also fixes a couple of bugs like not checking return value,
using "break" instead of "return;", etc.

I've been running with this patch for some time now on a
test (do-it-all) system.

Subject: [SCSI] SCSI core: Allow QUIESCE -> CANCEL sdev transition

We have to be able to remove SCSI devices even when they are suspended, so
QUIESCE -> CANCEL must be a legal state transition.  This patch (as727)
adds the transition to the state machine.

Subject: [SCSI] qla2xxx: Rework firmware-trace facilities.

- Defer firmware dump-data raw-to-textual conversion to
  user-space.
- Add module parameter (ql2xallocfwdump) to allow for per-HBA
  allocations of firmware dump memory.
- Dump request and response queue data as per firmware group
  request.
- Add extended firmware trace support for ISP24XX/ISP54XX chips.

Subject: [SCSI] qla2xxx: Add NVRAM 'Disable Serdes' bit support.

The host section of ISP24xx NVRAMs contain a new bit which
allows a user to selectively disable ports of an HBA.  These
ports (hosts) will not be presented to the midlayer.

Subject: [SCSI] qla2xxx: Correct 'loop-down' determination logic in
 qla2x00_fw_ready().

As there is no point in failing the initialization process when
firmware informs the host software that it could not transition
beyond a CONFIG_WAIT nor WAIT_FOR_LOGIN state.  Previous logic
would mark such conditions as a general *failure* and subsequently
tear-down the scsi-host during initialization.

Subject: [SCSI] Bogus disk geometry on large disks

We currently stuff a truncated size into the geometry logic and return the
result which can produce bizarre reports for a 4Tb array.  Since that
mapping logic isn't useful for disks that big don't try and map this way at
all.

Subject: [SCSI] aacraid: remove x86_64 IOMMU dependent code

This may seem like a DILLIGAF, but after chatting with the F/W folks,
there is no harm in dropping the page calculation as denoted in the
enclosed patch for these older adapters in this new age of 4GB+ memory
sticks. Any resource optimization within the old-old-old adapters for
systems with less than 4G of memory is of little consequence. The
existing AAC_QUIRK_31BIT flag in linit.c should look after the rest of
the legacy hardware DMA limitations.

Subject: [SCSI] fc transport: resolve scan vs delete deadlocks

In a prior posting to linux-scsi on the fc transport and workq
deadlocks, we noted a second error that did not have a patch:
  http://marc.theaimsgroup.com/?l=linux-scsi&m=114467847711383&w=2
  - There's a deadlock where scsi_remove_target() has to sit behind
    scsi_scan_target() due to contention over the scan_lock().

Subsequently we posted a request for comments about the deadlock:
  http://marc.theaimsgroup.com/?l=linux-scsi&m=114469358829500&w=2

This posting resolves the second error. Here's what we now understand,
and are implementing:

  If the lldd deletes the rport while a scan is active, the sdev's queue
  is blocked which stops the issuing of commands associated with the scan.
  At this point, the scan stalls, and does so with the shost->scan_mutex held.
  If, at this point, if any scan or delete request is made on the host, it
  will stall waiting for the scan_mutex.

  For the FC transport, we queue all delete work to a single workq.
  So, things worked fine when competing with the scan, as long as the
  target blocking the scan was the same target at the top of our delete
  workq, as the delete workq routine always unblocked just prior to
  requesting the delete.  Unfortunately, if the top of our delete workq
  was for a different target, we deadlock.  Additionally, if the target
  blocking scan returned, we were unblocking it in the scan workq routine,
  which really won't execute until the existing stalled scan workq
  completes (e.g. we're re-scheduling it while it is in the midst of its
  execution).

  This patch moves the unblock out of the workq routines and moves it to
  the context that is scheduling the work. This ensures that at some point,
  we will unblock the target that is blocking scan.  Please note, however,
  that the deadlock condition may still occur while it waits for the
  transport to timeout an unblock on a target.  Worst case, this is bounded
  by the transport dev_loss_tmo (default: 30 seconds).

Finally, Michael Reed deserves the credit for the bulk of this patch,
analysis, and it's testing. Thank you for your help.

Note: The request for comments statements about the gross-ness of the
  scan_mutex still stand.

Subject: [SCSI] fc transport: bug fix: correct references

Original post was incorrect as it didn't realize that we already had
a self-referenc due to device_initialize(), and we were really only
missing the put on our own reference. This was hidden by the other bug
which had the midlayer reusing stargets after they were already free,
which was doing too many puts on our rport.

Updating FC transport for:
- Add put in fc_rport_final_delete(), to release the rport.
  Prior, we were leaving the rport with a reference, thus the shost
  with references, etc. If the driver was unloaded, shosts and rports
  remained, along with work threads, etc
- Fix fc_rport_create failure path - too many put's on parent
- Add commenting to easily track ref taking.

Subject: [SCSI] scsi: Add allow_restart sysfs class attribute

This is a resend of a patch I generated in response to an email sent
by Ruben Faelens <parasietje@gmail.com>. His original email to
linux-scsi requested a method in which he could spin down a scsi disk
when not in use and have the kernel automatically spin it back up when
an I/O was generated to the disk. The infrastructure to automatically
spin a disk up has been in the scsi error handler for some time now,
but it is not enabled by default. This patch adds an sd sysfs attribute
which allows userspace to enable this behavior.

Subject: [SCSI] scsi: Device scanning oops for offlined devices (resend)

If a device gets offlined as a result of the Inquiry sent
during scanning, the following oops can occur. After the
disk gets put into the SDEV_OFFLINE state, the error handler
sends back the failed inquiry, which wakes the thread doing
the scan. This starts a race between the scanning thread
freeing the scsi device and the error handler calling
scsi_run_host_queues to restart the host. Since the disk
is in the SDEV_OFFLINE state, scsi_device_get will still
work, which results in __scsi_iterate_devices getting
a reference to the scsi disk when it shouldn't.

The following execution thread causes the oops:

CPU 0 (scan)				CPU 1 (eh)

---------------------------------------------------------
scsi_probe_and_add_lun
                        ....
                                        scsi_eh_offline_sdevs
                                        scsi_eh_flush_done_q
scsi_destroy_sdev
scsi_device_dev_release
                                        scsi_restart_operations
                                         scsi_run_host_queues
                                          __scsi_iterate_devices
                                           get_device
scsi_device_dev_release_usercontext
                                          scsi_run_queue
                                            <---OOPS--->

The patch fixes this by changing the state of the sdev to SDEV_DEL
before doing the final put_device, which should prevent the race
from occurring.

Original oops follows:

From: James Bottomley <James.Bottomley@steeleye.com>
Date: Wed, 28 Jun 2006 12:22:50 -0400
Subject: [SCSI] scsi_transport_sas: introduce a sas_port entity

this patch introduces a port object, separates out ports and phys,
with ports becoming the primary objects of the tree.

Subject: [SCSI] mptsas: wide port support

* Wide port support added - using James Bottomley's new SAS wide port API.
(There is a known problem in sas transport layer reported yesterday to
James. The Kobject dev.bus_ids for end devices are not unique across
expanders. I have added a work around in this patch, where I asigning
an unique port identifier for every port within the host - this solves
the problem, but I expect a fix from James in the sas transport).

* Adding target_alloc and target_destroy entry points, and moving code over
from the slave entry points.

* The renaming of some mptscsih_xxx functions declared in mptsas.c,
to mptsas_xxx.

* Target Reset moved from slave_destroy to hotplug work thread
handling (with regard to device removal). Also inhibit IO to end device
while device is being broken down . Talked to James Smart about this
at Linux Expo (with questions of how the fc transport handles this).

* Cleaning up the kzalloc's, and kfree's

Subject: [SCSI] mptsas: Adding 1078 ROC support

* Adding 1078 ROC (Raid On Chip) Support - New host adapter

* Moving all PCI Vendor/Device ids to using internal defines; a request
from Christoph/James B. some time ago for when the next chip was added.

* Removing SAS 1066/1066E Vendor/Device IDs, as there are no plans to
manufacture that controller.

Subject: [SCSI] atp870u: reduce huge stack usage

The atp870u driver is the largest stack eater reported by checkstack
(on x86_864, allmodconfig).  This converts the offending function
to kmalloc+kfree struct atp_unit instead of allocating it on the stack.
Was:
0x0000164c atp870u_probe [atp870u]:			3176
Now:
0x0000164c atp870u_probe [atp870u]:			408

Subject: [SCSI] st: remove unused st_buffer.in_use
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I noticed that in_use in st_buffer is not used. The patch below
against 2.6.17-rc3 removes it, assuming there is no future use for it.
It was tested in a sparc SS20 with a DLT4000.

Subject: [SCSI] iscsi: add target discvery event to transport class

Patch from david.somayajulu@qlogic.com:

Add target discovery event. We may have a setup where the iscsi traffic
is on a different netowrk than the other network traffic. In this case
we will want to do discovery though the iscsi card. This patch adds
a event to the transport class that can be used by hw iscsi cards that
support this.

Subject: [SCSI] iscsi: fixup set/get param functions

Reduce duplication in the software iscsi_transport modules by
adding a libiscsi function to handle the common grunt work.

This also has the drivers return specifc -EXXX values for different
errors so userspace can finally handle them in a sane way.

Also just pass the sysfs buffers to the drivers so HW iscsi can
get/set its string values, like targetname, and initiatorname.

Subject: [SCSI] iscsi: fix session refcouting

iscsi_tcp and iser cannot be rmmod from the kernel when sessions
are running because session removal is driven from userspace. For
those modules we get a module reference when a session is
created then drop it when the session is removed.

For qla4xxx, they can jsut remove the sessions from the pci remove
function like normal HW drivers, so this patch moves the module
reference from the transport class functions shared by all
drivers to the libiscsi functions only used be software iscsi
modules.

Subject: [SCSI] iscsi: rm channel usage from iscsi

I do not remember what I was thinking when we added the channel
as a argument to the session create function. It was probably
due to too much cut and paste work from the FC transport class.

The channel is meaningless for iscsi drivers so this patch drops
its usage everywhere in the iscsi related code.

Subject: [SCSI] iscsi: break up session creation into two stages

qla4xxx is initialized in two steps like other HW drivers.
It allocates the host, sets up the HW, then adds the host.
For iscsi part of HW setup is setting up persistent iscsi
sessions. At that time, the interupts are off and the driver
is not completely set up so we just want to allocate them.
We do not want to add them to sysfs and expose them to userspace
because userspace could try to do lots of fun things with them
like scanning and at that time the driver is not ready.

So this patch breakes up the session creation like other
functions that use the driver model in two the alloc
and add parts. When the driver is ready, it can then add
the sessions and userspace can begin using them.

This also fixes a bug in the addition error patch where
we forgot to do a get on the session.

Subject: [SCSI] iscsi: pass target nr to session creation

So the drivers do not use the channel numbers, but some do
use the target numbers. We were just adding some goofy
variable that just increases for the target nr. This is useless
for software iscsi because it is always zero. And for qla4xxx
the target nr is actually the index of the target/session
in its FW or FLASH tables. We needed to expose this to userspace
so apps could access those numbers so this patch just adds the
target nr to the iscsi session creation functions. This way
when qla4xxx's Hw thinks a session is at target nr 4
in its hw, it is exposed as that number in sysfs.

Subject: [SCSI] iscsi: add async notification of session events

This patch adds or modifies the transport class functions
used to notify userspace of session state events.

We modify the session addition up event and add a destruction event
to notify userspace of session creation, relogin and destruction.

And we modify the conn error event to be sent by broadcast
since multiple listeners may want to listen for it.

Subject: [SCSI] 53c700: fix breakage caused by the autosense update

A bit of a brown paper bag issue.  The previous patch to remove the soon
to be ripped out fields that were used in autosense actually broke the
driver.  This patch fixes it and has been tested (honestly).

Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

Subject: [SCSI] sg.c: Fix bad error handling in

I got a NULL derefrence in cdev_del+1 when called from sg_remove. By looking at
the code of sg_add, sg_alloc and sg_remove (all in drivers/scsi/sg.c) I found
out that sg_add is calling sg_alloc but if it fails afterwards it does not
deallocate the space that was allocated in sg_alloc and the redundant entry has
NULL in cdev. When sg_remove is being called, it tries to perform cdev_del to
this NULL cdev and fails.

Subject: [SCSI] mptsas: eliminate ghost devices

One of the current problems the mptsas driver has is that of "ghost"
devices (these are devices the firmware reports as existing, but what
they actually represent are the parents of a lower device), so for
example in my dual expander configuration, three expanders actually show
up, two for the real expanders but a third is created because the
firmware reports that the lower expander also has another expander
connected (which is simply the port going back to the upper expander).

The attached patch eliminates all these ghosts by not allocating any
devices for them if the SAS address is the SAS address of the parent.

There was a logic fault in scsi_io_completion() where zero transfer
commands that complete successfully were sent to the block layer as
not up to date.  This patch removes the if (good_bytes > 0) gate
around the successful completion, since zero transfer commands do have
good_bytes == 0.
