[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.

It looks like SGI use the same FC vendor and they already have a

[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.

[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.

[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.

from get_user_pages() call are properly handled

[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/
total 0
lrwxrwxrwx 1 root root 0 Aug 16 17:21 component-0 -> ../../../devices/pci0000:80/0000:80:04.0/host20/target20:1:0/20:1:0:0/
lrwxrwxrwx 1 root root 0 Aug 16 17:21 component-1 -> ../../../devices/pci0000:80/0000:80:04.0/host20/target20:1:1/20:1:1:0/
lrwxrwxrwx 1 root root 0 Aug 16 17:21 device -> ../../../devices/pci0000:80/0000:80:04.0/host20/target20:0:0/20:0:0:0/
-r--r--r-- 1 root root 16384 Aug 16 17:21 level
-r--r--r-- 1 root root 16384 Aug 16 17:21 resync
-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.

[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.

[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.

[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

[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.

[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.

[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

[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

[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.

[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?

[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

[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.

[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.

[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.

[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

[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.

[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.

[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.
