Subject: [PATCH] Add blk_rq_map_kern()

Add blk_rq_map_kern which takes a kernel buffer and maps it into
a request and bio. This can be used by the dm hw_handlers, old
sg_scsi_ioctl, and one day scsi special requests so all requests
comming into scsi will have bios. All requests having bios
should allow scsi to use scatter lists for all IO and allow it
to use block layer functions.

Subject: [PATCH] Cleanup blk_rq_map_* interfaces

Change the blk_rq_map_user() and blk_rq_map_kern() interface to require
a previously allocated request to be passed in. This is both more efficient
for multiple iterations of mapping data to the same request, and it is also
a much nicer API.

 aic doesnt work anymore after this change which appeared int 2.6.13-rc1:
 [SCSI] aic7xxx/aic79xx: remove useless byte order macro cruft

 2 files did not include byteorder.h, aic died with panic
 "Unknown opcode encountered in seq program"
 This patch fixes it for me.

Subject: [SCSI] host state model update: reimplement scsi_host_cancel

Remove the old scsi_host_cancel function as it has not been working for
sometime do to the device list possibly being empty when it is called and
possible race issues. Add setting of SHOST_CANCEL at the state of beginning
of scsi_remove_host.

From 60a13213840296b1e32d6781653a0eaa83d04382 Mon Sep 17 00:00:00 2001
From: Hannes Reinecke <hare@suse.de>
Date: Fri, 22 Jul 2005 16:42:28 +0200
Subject: [SCSI] aic79xx: Remove busyq

From: Jeff Garzik <jgarzik@pobox.com>

This patch removes the busyq in aic79xx and uses the command-queue from
the midlayer instead. Additionally some dead code is removed.

Signed-off-by: Hannes Reinecke <hare@suse.de>

Subject: [SCSI] aic79xx: update to use scsi_transport_spi

This patch updates the aic79xx driver to take advantage of the
scsi_transport_spi infrastructure. Patch is quite a mess as some
procedures have been reshuffled to be closer to the aic7xxx driver.

Rejections fixed and

From a4b53a11806f5c0824eb4115b1de8206ed7bb89a Mon Sep 17 00:00:00 2001
From: Hannes Reinecke <hare@suse.de>
Date: Mon, 1 Aug 2005 09:52:56 +0200
Subject: [SCSI] aic79xx: DV parameter settings

This patch updates various scsi_transport_spi parameters with the actual
parameters used by the driver internally.
Domain Validation for all devices should now work properly.

Subject: [SCSI] aic79xx: fix up transport settings

There's a slight problem in the way you've done the transport
parameters; reading from the variables actually produces the current
settings, not the ones you just set (and there's usually a lag because
devices don't renegotiate until the next command goes over the bus).  If
you set the bit immediately, you get into the situation where the
transport parameters report something as being set even if the drive
cannot support it.

I patched the driver to do it this way and also corrected a panic in the
proc routines.

Subject: [SCSI] add missing hold_mcs parameter to the spi transport class

This parameter is important only to people who take the time to tune the
margin control settings, otherwise it's completely irrelevant.  However,
just in case anyone should want to do this, it's appropriate to include
the parameter.

I don't do anything with it in DV by design, so the parameter will come
up as off by default, so if anyone actually wants to play with the
margin control settings they'll have to enable it under the
spi_transport class first.

I also updated the transfer settings display to report all of the PPR
settings instead of only DT, IU and QAS

Subject: [SCSI] aic79xx: fixup DT setting

this patch is just a cross-port of the fixup for aic7xxx DT settings.
As the same restrictions apply for aic79xx also (DT requires wide
transfers) the dt setting routine should be modified equivalently.
And an invalid period setting will be caught by ahd_find_syncrate()
anyway.

Subject: [SCSI] aacraid: interupt mitigation

Received from Mark Salyzyn from Adaptec:

If more than two commands are outstanding to the controller, there is no
need to notify the adapter via a PCI bus transaction of additional
commands added into the queue; it will get to them when it works through
the produce/consumer indexes.

This reduced the PCI traffic in the driver to submit a command to the
queue to near zero allowing a significant number of commands to be
turned around with no need to block for the PCI bridge to flush the
notify request to the adapter.

Interrupt mitigation has always been present in the driver; it was
turned off because of a bug that prevented one from realizing the
usefulness of the feature. This bug is fixed in this patch.

Subject: [SCSI] aacraid: driver shutdown method

Add in pci shutdown method so that the adapter shuts down correctly and
flushes its cache. Shutdown should also disable the adapter's interrupt
when shutdown (in particularly if the driver is rmmod'd) to prevent
spurious hardware activities.

Subject: [SCSI] aacraid: remove duplicate io callback code

Received from Mark Salyzyn from Adaptec:

This patch removes the duplicate code in the write_callback command
completion handler, and renames read_callback to io_callback. Optimized
the lba calculation into the debug print routine macro to optimize the
i/o code path.

Subject: [SCSI] aacraid: aif registration timeout fix

Received from Mark Salyzyn from Adaptec:

If the Adapter is quiet and does not produce an AIF event packets to be
picked up by the management applications for longer than the timeout
interval of two minutes, the cleanup code that deals with aging out
registrants could erroneously drop the registration. The timeout is
there to clean up should the management application die and fail to poll
for updated AIF event packets.

Moving the timer update from the ioctl code that delivers an AIF to the
polling registrant to the bottom of the ioctl means the timeout is reset
with any management application polling activity regardless if an AIF is
delivered or not removing the erroneous timeout cleanups.

Subject: [SCSI] aacraid: sgraw command support

Received from Mark Salyzyn from Adaptec:

This patch adds support for the new raw io command. This new command
offers much larger io commands, is more friendly to the internal firmware
structure requiring less translation efforts by the firmware and offers
support for targets greater than 2TB (patch to support >2TB will
be sent in the future).

Subject: [SCSI] aacraid: correct use of cmd->timeout field

The cmd->timeout field has been obsolete for a while now.  While looking
to remove it, I came across this use in the aacraid driver.  It looks
like you want to initialise the firmware with the current timeout of the
command (in seconds), so the value I think you should be using is
cmd->timeout_per_command.

Subject: [SCSI] drivers/scsi/st.c: add reference count and related fixes

I have rediffed the patch against 2.6.13-rc5, done a couple of cosmetic
cleanups, and run some tests.  Brian King has acknowledged that it fixes the
problems he has seen. Seems mature enough for inclusion into 2.6.14 (or
later)?

Nate's explanation of the changes:

I've attached patches against 2.6.13rc2. These are basically identical
to my earlier patches, as I found that all issues I'd seen in earlier
kernels still existed in this kernel.

To summarize, the changes are: (more details in my original email)

- add a kref to the scsi_tape structure, and associate reference
counting stuff

- set sr_request->end_io = blk_end_sync_rq so we get notified when an IO
is rejected when the device goes away

- check rq_status when IOs complete, else we don't know that IOs
rejected for a dead device in fact did not complete

- change last_SRpnt so it's set before an async IO is issued (in case
st_sleep_done is bypassed)

- fix a bogus use of last_SRpnt in st_chk_result

Subject: [SCSI] add global timeout to the scsi mid-layer

There are certain rogue devices (and the aic7xxx driver) that return
BUSY or QUEUE_FULL forever.  This code will apply a global timeout (of
the total number of retries times the per command timer) to a given
command.  If it is exceeded, the command is completed regardless of its
state.

The patch also removes the unused field in the command: timeout and
timeout_total.

This solves the problem of detecting an endless loop in the mid-layer
because of BUSY/QUEUE_FULL bouncing, but will not recover the device.
In the aic7xxx case, the driver can be recovered by sending a bus reset,
so possibly this should be tied into the error handler?

Subject: [SCSI] aacraid: adapter support update

Received from Mark Salyzyn

This patch adds the product ID for the ICP9067MA adapter.

The entries for the ICP9085LI, ICP5085BR, IBM8k & ASR4810SAS were
incorrect and would not initialize the adapters correctly.

Subject: [SCSI] blacklist addition.

When run on a kernel that scans all LUNs, a certain crappy
scsi scanner reports the same LUN over and over..
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=155457

Aparently they were so shamed by this, they chose to remain
anonymous. Though it seems the blacklist code handles
anonymous vendors just fine.

There's a spurious (and illegal since it's marked __exit) call to
ahc_linux_exit() in ahc_linux_init() which causes a double list
deletion of the transport class; remove it.

Subject: [SCSI] Make the HSG80 a REPORTLUN2 device

From: 	Steve Wilcox <spwilcox@att.com>

In order to properly report LUN's > 7, the DEC HSG80 definition in
scsi_devinfo.c needs to include BLIST_REPORTLUN2 rather than
BLIST_SPARSELUN.  I've tested this change with several HSG firmware
revisions and with both Emulex and Qlogic HBA's.

Subject: [SCSI] lpfc driver 8.0.30 : fix iocb reuse initialization

IOCB BDE not getting fully initialized during reuse

Symptoms: Driver gets Status 3 and Reason 0x13 on IOCB completions.

Cause: The IOCB bpl.bdeSize and bdeFlags are not getting initialized on reuse.

Fix: Reinitialize these fields in prep_dma each time an IOCB is used.

Subject: [SCSI] lpfc driver 8.0.30 : dev_loss and nodev timeouts

Fix handling of the dev_loss and nodev timeouts.

Symptoms: when remote port disappears for a period of time longer then
either nodev_tmo or dev_loss_tmo, the lpfc driver worker thread will
stall removing that remote port.

Cause: removing remote port involves un-blocking and sync-ing
corresponding block device queue. But corresponding node in the lpfc
driver is still in the NPR(?node port recovery?) state and mid-layer
gets SCSI_MLQUEUE_HOST_BUSY as a return value when it is trying to call
queuecommand() with command for that node (AKA remote port)

Fix: Instead of returning SCSI_MLQUEUE_HOST_BUS from queuecommand() for
nodes in NPR states complete it with retry-able error code  DID_BUS_BUSY

Replace use of lpfc_put_lun with midlayer's int_to_scsilun

Remove driver's local definition of lpfc_put_lun (which converts an
int back to a 64-bit LUN) and replace it's use with the recently added
int_to_scsilun function provided by the midlayer.

Note: Embedding midlayer structure in our structure caused
need for more files to include midlayer headers.

Subject: [SCSI] add ability to deny binding to SPI transport class

This patch is necessary if we begin exposing underlying physical disks
(which can attach to the SPI transport class) of the hardware RAID
cards, since we don't want any SPI parameters binding to the RAID
devices.

Subject: [SCSI] correct transport class abstraction to work outside SCSI

I recently tried to construct a totally generic transport class and
found there were certain features missing from the current abstract
transport class.  Most notable is that you have to hang the data on the
class_device but most of the API is framed in terms of the generic
device, not the class_device.

These changes are two fold

- Provide the class_device to all of the setup and configure APIs
- Provide and extra API to take the device and the attribute class and
  return the corresponding class_device

Subject: [SCSI] use scatter lists for all block pc requests and simplify hw
 handlers

Here's the proof of concept for this one.  It converts scsi_wait_req to
do correct REQ_BLOCK_PC submission (and works nicely in my setup).

The final goal should be to eliminate struct scsi_request, but that
can't be done until the character submission paths of sg and st are also
modified.

There's some loss of functionality to this: retries are no longer
controllable (except by setting REQ_FASTFAIL) and the wait_req API needs
to be altered, but it looks very nice.

Original From: Mike Christie <michaelc@cs.wisc.edu>

Add scsi_execute_req() as a replacement for scsi_wait_req()

Fixed up various pieces (added REQ_SPECIAL and caught req use after
free)

Subject: [SCSI] fix transport class corner case after rework

If your transport class sets the ATTRIBUTE_CONTAINER_NO_CLASSDEVS flag,
then its configure method never gets called.  This patch fixes that so
that the configure method is called with a NULL classdev.

Also remove a spurious inverted comma in the transport_class comments.

Subject: [SCSI] ibmvscsi eh locking

With the removal of the spinlocking around eh calls, we need to add a
little more locking back in, otherwise we do some naked list
manipulation.

Subject: [SCSI] ibmvscsi timeout fix

This patch fixes a long term borkenness in
ibmvscsi where we were using the wrong timeout
field from the scsi command (and using the
wrong units.)  Now broken by the fact that the
scsi_cmnd timeout field is gone entirely.
This only worked before because all the SCSI
targets assumed that 0 was default.

Subject: [SCSI] sr.c: Fix getting wrong size

Here's the problem. Try to do this on 2.6.12:
- Kill udev and HAL
- Insert a CD-ROM into a SCSI or USB CD-ROM drive
- Run dd if=/dev/scd0
- cat /sys/block/sr0/size
- Eject the CD, insert a different one
- Run dd if=/dev/scd0
This is likely to do "access beyond the end of device", if you let it
- cat /sys/block/sr0/size
This shows the size of a previous CD, even though dd was supposed
to revalidate the device.
- Run dd if=/dev/scd0
The second run of dd works correctly!

The bug was introduced in 2.5.31, when Al fixes the recursive opens
in partitioning. Before, the code worked like this:
- Block layer called cdrom_open directly
- cdrom_open called sr_open
- sr_open called check_disk_change
- check_disk_change called sr_media_change
- sr_media_change did cd->needs_disk_change=1
- before returning sr_open tested cd->needs_disk_change
  and called get_sector_size.

In 2.6.12, the check_disk_change is called from cdrom_open only. Thus:
- Block layer calls sr_bd_open
- sr_bd_open calls cdrom_open
- cdrom_open calls sr_open
- sr_open tests cd->needs_disk_change, which wasn't set yet; returns
- cdrom_open calls check_disk_change
- check_disk_change calls sr_media_change
- sr_media_change does cd->needs_disk_change=1, but nobody cares

From 33aa687db90dd8541bd5e9a762eebf880eaee767 Mon Sep 17 00:00:00 2001
From: James Bottomley <jejb@titanic.(none)>
Date: Sun, 28 Aug 2005 11:31:14 -0500
Subject: [SCSI] convert SPI transport class to scsi_execute

This one's slightly more difficult.  The transport class uses
REQ_FAILFAST, so another interface (scsi_execute) had to be invented to
take the extra flag.  Also, the sense functions are shifted around to
allow spi_execute to place data directly into a struct scsi_sense_hdr.
With this change, there's probably a lot of unnecessary sense buffer
allocation going on which we can fix later.

From ea73a9f23906c374b697cd5b0d64f6dceced63de Mon Sep 17 00:00:00 2001
From: James Bottomley <jejb@titanic.(none)>
Date: Sun, 28 Aug 2005 11:33:52 -0500
Subject: [SCSI] convert sd to scsi_execute_req (and update the
 scsi_execute_req API)

This one removes struct scsi_request entirely from sd.  In the process,
I noticed we have no callers of scsi_wait_req who don't immediately
normalise the sense, so I updated the API to make it take a struct
scsi_sense_hdr instead of simply a big sense buffer.

Subject: [SCSI] convert sr to scsi_execute_req

This follows almost the identical model to sd, except that there's one
ioctl which returns raw sense data, so it had to use scsi_execute()
instead.

The 3ware emulated commands all expect they are executing in the
use_sg == 0 case, which isn't true either in the block layer rework or
an SG_IO ioctl.

Fix this by adding the correct kmapping of the first element in the sg

Subject: [SCSI] fix sense buffer length handling problem

The new bio code was incorrectly converted from stack allocated to
kmalloc'd buffer handling.  There are two places where it incorrectly
uses sizeof(*sense) to get the size of the sense buffer.  This
actually produces one, so no sense data was ever getting back, causing
failure in things like disk spin up.

Subject: [SCSI] correct attribute_container list usage

One of the changes in the attribute_container code in the scsi-misc tree
was to add a lock to protect the list of devices per container.  This,
unfortunately, leads to potential scheduling while atomic problems if
there's a sleep in the function called by a trigger.

The correct solution is to use the kernel klist infrastructure instead
which allows lockless traversal of a list.

Subject: [SCSI] attribute container final klist fixes

Since the attribute container deletes from a klist while it's walking
it, it is vulnerable to the problem (and fix) here:

http://marc.theaimsgroup.com/?l=linux-scsi&m=112485448830217

The attached fixes this (but won't compile without the above).

It also fixes the logical reversal in the traversal loop which meant
that we were never actually traversing the loop to hit this bug in the
first place.

Subject: [SCSI] embryonic RAID class

The idea behind a RAID class is to provide a uniform interface to all
RAID subsystems (both hardware and software) in the kernel.

To do that, I've made this class a transport class that's entirely
subsystem independent (although the matching routines have to match per
subsystem, as you'll see looking at the code).  I put it in the scsi
subdirectory purely because I needed somewhere to play with it, but it's
not a scsi specific module.

I used a fusion raid card as the test bed for this; with that kind of
card, this is the type of class output you get:

jejb@titanic> ls -l /sys/class/raid_devices/20\:0\:0\:0/

-r--r--r--  1 root root 16384 Aug 16 17:21 state

So it's really simple: for a SCSI device representing a hardware raid,
it shows the raid level, the array state, the resync % complete (if the
state is resyncing) and the underlying components of the RAID (these are
exposed in fusion on the virtual channel 1).

As you can see, this type of information can be exported by almost
anything, including software raid.

The more difficult trick, of course, is going to be getting it to
perform configuration type actions with writable attributes.

Subject: This patch fixes in st.c the bug in the signed/unsigned int
 comparison reported by Doug Gilbert and fixed by him in sg.c (see [PATCH] sg
 direct io/mmap oops). Doug fixed the comparison in sg.c. This fix for st.c
 does not touch the comparison but makes both arguments signed to remove the
 problem. The new code is adapted from linux/fs/bio.c.

Subject: [SCSI] sg direct io/mmap oops, st sync

This patch adopts the same solution as proposed by Kai M. in
a post titled: "[PATCH] SCSI tape signed/unsigned fix".
The fix is in a function that the sg driver borrowed from
the st driver so its maintenance is a little easier if
the functions remain the same after the fix.

   - change nr_pages type from unsigned to signed so errors
     from get_user_pages() call are properly handled

This was noticed by Doug Bazamic and the fix found by Mark Salyzyn at
Adaptec.

There was an error in the BUG_ON() statement that validated the
calculated fib size which can cause the driver to panic.

From 7524f9b9e72cd36f0a70defcd424eba81c180f42 Mon Sep 17 00:00:00 2001

Subject: [SCSI] qla2xxx: Use dma_get_required_mask() in determining the
 'ideal' DMA mask.

In order to efficiently utilise the ISP's IOCB
request-queue, use the dma_get_required_mask() function to
determine the use of command-type 2 or 3 IOCBs when queueing
SCSI commands.  This applies to ISP2[123]xx chips only, as
the ISP24xx uses command-type 7 IOCBs which use 64bit DSDs.

Subject: [SCSI] qla2xxx: Correct domain/area exclusion logic.

In an FL topology, limit port recognition to those devices
not within the same area and domain of the ISP.  The
firmware will recogonize such devices during local-loop
discovery.

Some devices may respond to a PLOGI before they have
completed their fabric login or they may not be a public
device. In this case they will report:

        domain == 00
        area == 00
        alpa == <XX>

which is valid. Exclude such devices from local loop
discovery.

Subject: [SCSI] qla2xxx: Remove redundant call to pci_unmap_sg().

In a corner-case failure where the request-q does not
contain enough entries for a given request, pci_unmap_sg()
would be called twice.  Remove direct call and let the
failure-path logic handle the unmapping.

Subject: [SCSI] qla2xxx: Remove bad call to fc_remove_host() during probe
 failure.

fc_remove_host() should only be called after a scsi_host has
been successfully added via scsi_add_host() -- any failures
while qla2xxx probing would result in an incorrect call to
fc_remove_host() during cleanup.

Subject: [SCSI] ibmvscsi: handle large scatter/gather lists

The maximum size of a scatter-gather list that the current IBM VSCSI
Client can handle is 10.  This patch adds large scatter-gather support
to the client so that it is capable of handling up to SG_ALL(255)
number of requests in the scatter-gather list.

Subject: [SCSI] return success after retries in scsi_eh_tur

The problem lies in the way the error handler uses TEST UNIT READY to
tell whether error recovery has succeeded.  The scsi_eh_tur function
gives up after one round of retrying; after that it decides that more
error recovery is needed.

However TUR is liable to report sense data indicating a retry is needed
when in fact error recovery has succeeded.  A typical example might be
SK=2, ASC=4, ASCQ=1 (Logical unit in process of becoming ready).  The mere
fact that we were able to get a sensible reply to the TUR should indicate
that the device is working well enough to stop error recovery.

I ran across a case back in January where this happened.  A CD-ROM drive
timed out the INQUIRY command, and a device reset fixed the blockage.
But then the drive kept responding with 2/4/1 -- because it was spinning
up I suppose -- until the error handler gave up and placed it offline.
If the initial INQUIRY had received the 2/4/1 instead, everything would
have worked okay.  It doesn't seem reasonable for things to fail just
because the error handler had started running.

Subject: [SCSI] sd: pause in sd_spinup_disk for slow USB devices

This patch adds a delay tailored for USB flash devices that are slow to
initialize their firmware.  The symptom is a repeated Unit Attention with
ASC=0x28 (Not Ready to Ready transition).  The patch will wait for up to 5
seconds for such devices to become ready.  Normal devices won't send the
repeated Unit Attention sense key and hence won't trigger the patch.

This fixes a problem with James Roberts-Thomson's USB device, and I've
seen several reports of other devices exhibiting the same symptoms --
presumably they will be helped as well.

Three years later...

It looks like SGI use the same FC vendor and they already have a
workaround for this issue. The following patch adds the IBM version of
it.

Subject: [SCSI] fix SCSI_IOCTL_PROBE_HOST

This returns always false with new-style drivers right now.  Make it
return always true instead, as a host must be present if we are able
to call the ioctl (without a host attached there would be no device
node to call on..)

Subject: [SCSI] quieten messages on scsi_execute commands

scsi_io_completion() can be a bit noisy about certain conditions.
Previously this wasn't a problem for internally generated commands,
since they never hit it.  However, since we do all SCSI commands via
bios, now they do.  user CD testers like magicdev are now getting not
ready messages every time they touch the CD to see if there's anything
in it.

Fix this by making all scsi_execute commands REQ_QUIET and making
scsi_finish_io() not say anything for REQ_QUIET.
