In preparation for bidi we abstract all IO members of scsi_cmnd,
that will need to duplicate, into a substructure.
- Group all IO members of scsi_cmnd into a scsi_data_buffer
structure.
- Adjust accessors to new members.
- scsi_{alloc,free}_sgtable receive a scsi_data_buffer instead of
scsi_cmnd. And work on it.
- Adjust scsi_init_io() and scsi_release_buffers() for above
change.
- Fix other parts of scsi_lib/scsi.c to members migration. Use
accessors where appropriate.
- fix Documentation about scsi_cmnd in scsi_host.h
- scsi_error.c
* Changed needed members of struct scsi_eh_save.
* Careful considerations in scsi_eh_prep/restore_cmnd.
- sd.c and sr.c
* sd and sr would adjust IO size to align on device's block
size so code needs to change once we move to scsi_data_buff
implementation.
* Convert code to use scsi_for_each_sg
* Use data accessors where appropriate.

Since the SCSI layer uses the request queues from the block layer, blktrace can
also be used to trace the requests to all SCSI devices (like SCSI tape drives),

sg device files. With this change, blktrace can be used for SCSI devices like
for disks, e.g.: blktrace -d /dev/sg1 -o - | blkparse -i -

with the fib context managed by the trio of ioctls that are used by
the RAID management applications to retrieve Adapter Initiated FIBs. I
merely expanded the fib lock to include the fib context. There have
been no field reports of any issues generally because the applications
are relatively static and do not come and go often enough to stress
this area. I bloated this patch a little with some space junk.

This removes static array sense_buffer in scsi_cmnd and uses
dynamically allocated sense_buffer (with GFP_DMA).
The reason for doing this is that some architectures need cacheline
aligned buffer for DMA:
http://lkml.org/lkml/2007/11/19/2
The problems are that scsi_eh_prep_cmnd puts scsi_cmnd::sense_buffer
to sglist and some LLDs directly DMA to scsi_cmnd::sense_buffer. It's
necessary to DMA to scsi_cmnd::sense_buffer safely. This patch solves
these issues.
__scsi_get_command allocates sense_buffer via kmem_cache_alloc and
attaches it to a scsi_cmnd so everything just work as before.

The cards being added are supported in a limited sense already through
family matching, but we needed to add some functionality to the driver
to expose selectively the physical drives. These Physical drives are
specifically marked to not be part of any array and thus are declared
JBODs (Just a Bunch Of Drives) for generic SCSI access.
We report that this is the second patch in a set of two, but merely
depends on the stand-alone functionality of the first patch which adds
in that case the ability to report a driver feature flag via sysfs. We
leverage that functionality by reporting that this driver now supports
this new JBOD feature for the controller so that the array management
applications may react accordingly and guide the user as they manage
the controller.

Feature enhancement, adding a 'flags' entry that will reside in the
host controller's tree, with a newline separated list of arbitrary
ascii named features that indicate whether the combination of driver
and controller has support for said feature. Breaking from the
one-line output typical of sysfs entries, newline was added to tailor
for grep, or simple gets line by line string match within an
application. I added one for a compiler time check for existence of
debug print output, one for an optional manifest defined enhanced
status reporting in the logs, and one for runtime reporting whether
the controller and driver supports arrays larger than 2TB. Adaptec's
storage management software uses the last flag to determine whether to
make available the creation of arrays larger than 2TB, otherwise a
warning is posted.

FCE support enables the firmware to record FC extended link
services and basic link services frames which have been
transmitted and received by the ISP. This allows for a limited
view of the FC traffic through the ISP without using a FC
analyzer. This can be useful in situations where a physical
connection to the FC bus is not possible.
The driver exports this information in two ways -- first, via a
debugfs node exported for all supported ISPs under:
<debugfs_mount_point>/qla2xxx/qla2xxx_<host_no>/fce
where a read of the 'fce' file will provide a snapshot of the
firmware's FCE buffer; and finally, the FCE buffer will be
extracted during a firmware-dump scenario.

Actually there are several but one is trivially fixed
1. FSACTL_GET_NEXT_ADAPTER_FIB ioctl does not lock dev->fib_list
but needs to
2. Ditto for FSACTL_CLOSE_GET_ADAPTER_FIB
3. It is possible to construct an attack via the SRB ioctls where
the user obtains assorted elevated privileges. Various approaches are
possible, the trivial ones being things like writing to the raw media
via scsi commands and the swap image of other executing programs with
higher privileges.
So the ioctls should be CAP_SYS_RAWIO - at least all the FIB manipulating
ones. This is a bandaid fix for #3 but probably the ioctls should grow
their own capable checks. The other two bugs need someone competent in that
driver to fix them.

Due to an internal limit associated with the AdapterTypeText field,
SMC required a product ID that overloaded the combined vendor and
product ID. A decision was made to ship the SMC products without a
vendor string dropping the defacto space that used to delineate vendor
and product to boot. To correct this, we needed to adjust the code in
the driver to parse out the vendor and product strings for the
adapter. We match of 'AOC' in the AdapterTypeText, if so we set the
vendor to SMC and place the entire AdapterTypeText into the product
field.
This only affects the cosmetic presentation of the Adapter vendor and
product in the logs and in sysfs.

This patch fixes two bugs pointed by James Bottomley:
1. the if (!sym_data->io_reset). That variable is only ever filled
by a stack based completion. If we find it non empty it means
this code has been entered twice and we have a severe problem,
so that should just become a BUG_ON(sym_data->io_reset).
2. sym_data->io_reset should be set to NULL before the routine is
exited otherwise the PCI recovery code could end up completing
what will be a bogus pointer into the stack.

The adapter queue is divided up equally to all the arrays to prevent
command starvation to any individual array. On the other hand,
physical targets are only granted a queue depth of one each. The code
prior to this patch used to deal with the incremental discovery of
targets, but the driver knows how many arrays are present prior to the
scan so this knowledge is used to generate a better estimate for the
queue depth.
Remove the capability of 'physical=0' from preventing access to the
class of adapters that have the RAID/SCSI mode of operation since none
of the physicals on the SCSI channel are candidates ever for an array.
As always, the user can override this default queue depth policy by
making the appropriate adjustments utilizing sysfs.

command from the management software were outstanding on a bug only
present on a class of RAID Adapters that require a hardware reset
rather than a commanded reset. The net result was an attempt to time
out the management software command as if it came from the SCSI layer
resulting in an OS panic.
Adapters that use commanded reset, management commands are returned
failed by the Adapter correctly. The adapter firmware panic that
resulted in this condition was also resolved, and there were no

* s/qc->pad_sgent/qc->extra_sg[]/. Because chaining consumes one sg

* Padding setup is moved into ata_sg_setup_extra() which is organized
in a way that future addition of other extra sg entries is easy.
* qc->orig_n_elem is unused and removed.
* qc->n_elem now contains the number of sg entries that LLDs should
map. qc->mapped_n_elem is added to carry the original number of

* The last sg of the original sg list is used to chain to extra sg
list. The original last sg is pointed to by qc->last_sg and the

We were using the device delete sysfs file to remove each device
then logout. Now in 2.6.21 this will not work because
the sysfs delete file returns immediately and does not wait for
the device removal to complete. This causes a hang if a cache sync
is needed during shutdown. Before .21, that approach had other
problems, so this patch fixes the shutdown code so that we remove the target
and unbind the session before logging out and shut down the session

I thought we may not need the eh mutex during host reset, but that is wrong
with the new shutdown code. When start_session_recovery sets the state to
terminate then drops the session lock. The scsi eh thread could then grab the
session lock see that we are terminating and then return failed to scsi-ml.
scsi-ml's eh then owns the command and will do whatever it wants
with it. But then the iscsi eh thread could grab the session lock
and want to complete the scsi commands that we in the LLD, but
it no longer owns them and kaboom.

iscsi_pool_init simplified
iscsi_pool_init currently has a lot of duplicate kfree() calls it does
when some allocation fails. This patch simplifies the code a little by
using iscsi_pool_free to tear down the pool in case of an error.
iscsi_pool_init also returns a copy of the item array to the caller.
Not all callers use this array, so we make it optional.
Instead of allocating a second array and return that, allocate just one
array, of twice the size.
Update users of iscsi_pool_{init,free}
This patch drops the (now useless) second argument to
iscsi_pool_free, and updates all callers.
It also removes the ctask->r2ts array, which was never
used anyway. Since the items argument to iscsi_pool_init
is now optional, we can pass NULL instead.

at libiscsi generic code
- currently code assumes a storage space of pdu header is allocated
at llds ctask and is pointed to by iscsi_cmd_task->hdr. Here I add
a hdr_max field pertaining to that storage, and an hdr_len that
accumulates the current use of the pdu-header.
- Add an iscsi_next_hdr() inline which returns the next free space
to write new Header at. Also iscsi_next_hdr() is used to retrieve
the address at which to write the header-digest.
- Add iscsi_add_hdr(length). What the user do is calls iscsi_next_hdr()
for address of the new header, than calls iscsi_add_hdr(length) with
the size of the new header. iscsi_add_hdr() will check if space is
available and update to the new size. length must be padded according
to standard.
- Add 2 padding inline helpers thanks to Olaf. Current patch does not
use them but Following patches will.
Also moved definition of ISCSI_PAD_LEN to iscsi_proto.h which had
PAD_WORD_LEN that was never used anywhere.
- Let iscsi_prep_scsi_cmd_pdu() signal an Error return since now it is
possible that it will fail.
- I was tired of yet again writing a "this is a digest" comment next to
sizeof(__u32) so I defined a new ISCSI_DIGEST_SIZE. Now I don't need
any comments. Changed all places that used sizeof(__u32) or "4" in
connection to a digest.
iscsi_tcp specific code
- At struct iscsi_tcp_cmd_task allocate maximum space allowed in
standard for all headers following the iscsi_cmd header. and mark
it so in iscsi_tcp_session_create()
- At iscsi_send_cmd_hdr() retrieve the correct headers size and

As reported in http://bugzilla.kernel.org/show_bug.cgi?id=3D9133 it was
discovered that the PERC line of controllers lacked a key 64 bit
ScatterGather capable SCSI pass-through function. The adapters are still
capable of 64 bit ScatterGather I/O commands, but these two can not be
mixed. This problem was exacerbated by the introduction of the SCSI
Generic access to the DASD physical devices.
The fix for users before this patch is applied is aacraid.dacmode=3D0 on
the kernel command line to disable 64 bit I/O.
The enclosed patch introduces a new adapter quirk and tries to limp
along by enabling pass-through in situations where memory is 32 bit
addressable on 64 bit machines, or disable the pass-through functions
altogether. I expect that the check for 32 bit addressable memory to be
controversial in that it can be incorrect in non-Dell non-Intel systems
that PERC would never be installed under, the alternative is to disable
pass-through in all cases which could be reported as another regression.
Pass-through is used for SCSI Generic access to the physical devices, or
for the management applications to properly function.
In systems where this patch has disabled pass-through because it is
unsupportable in combination with I/O performance, the user can choose
to enable pass-through by turning off dacmode (aacraid.dacmode=3D0) or
limiting the discovered kernel memory (mem=3D4G) with an associated loss
in runtime performance. If we chose instead to turn off 64 bit dacmode
for the adapters with this quirk, then this would be reported as another
regression.

CRQ send errors that return with H_CLOSED should return with
SCSI_MLQUEUE_HOST_BUSY until firmware alerts the client of a CRQ
transport event. The transport event will either reinitialize and
requeue the requests or fail and return IO with DID_ERROR.
To avoid failing the eh_* functions while re-attaching to the server
adapter this will retry for a period of time while ibmvscsi_send_srp_event
returns SCSI_MLQUEUE_HOST_BUSY.
In ibmvscsi_eh_abort_handler() the loop includes the search of the
event list. The lock on the hostdata is dropped while waiting to try
again after failing ibmvscsi_send_srp_event. The event could have been
purged if a login was in progress when the function was called.
In ibmvscsi_eh_device_reset_handler() the loop includes the call to
get_event_struct() because a failing call to ibmvscsi_send_srp_event()
will have freed the event struct.

Some SCSI tape medium changers that need the BLIST_SINGLELUN flag have
the medium changer at one LUN and the tape drive at a different LUN.
The inquiry string of the tape drive may be different from that of the
medium changer. In order for single_lun to be effective, every
scsi_device under a given scsi_target must have it set. This means that
there needs to be a blacklist entry for BOTH the medium changer AND the
tape drive, which is impractical because some medium changers may be
paired with a variety of different tape drive models. It makes more
sense to put the single_lun flag in scsi_target instead of scsi_device,
which causes every device at a given target ID to inherit the single_lun
flag from one LUN. This makes it possible to blacklist just the medium
changer and not the tape drive.

The 3ware 9500S-8 SATA RAID controller exhibits terrible write
performance when PCI memory-write-and-invalidate is disabled. This is
easy to demonstrate by replacing pci_try_set_mwi() in the patch below
with pci_clear_mwi(). My benchmarks show the following:
MWI disabled: 15 MB/s write, 330 MB/s read
MWI enabled: 240 MB/s write, 330 MB/s read
Most motherboards will enable MWI without the driver having to set it
explicitly, so most people probably wouldn't encounter this problem.
For the few motherboards that don't enable it, this patch could give a
16x performance improvement for writing.
This issue does not seem to affect the 9550SX controller, but the patch
doesn't hurt it either. I haven't tested any of the other 3ware

Some of our vendors have requested that our adapters ignore the hardware
reset attempts during recovery and have enforced this with changes in
Adapter Firmware. Some of our customers have requested the option to be
able to reset the adapter under adverse adapter failure, we even had a
few defects reported here considering it a regression that the Adapter
could not be reset. This patch addresses this dichotomy. The user can
force the adapter to be reset if it supports the IOP_RESET_ALWAYS
command, in cases where the adapter has been programmed to ignore the
reset, by setting the aacraid.check_reset parameter to a value of -1.
The driver will not reset an Adapter that does not support the reset

I was working on patches which add new transport error values, when I
noticed that DID_REQUEUE was not in the hostbyte_table. I do not think
there is any way to hit the code path where scsi_show_result is called
and where you return DID_REQUEUE, because DID_REQUEUE causes scsi-ml to
always requeue the command. However, for completeness and because I want
to one day send a patch that tries to add new host bytes values, I am
sending this patch.
