From 4c9c8d782c8dddc5e97d33210e8a993cec6bc168 Mon Sep 17 00:00:00 2001

Subject: [SCSI] gdth: PCI probe cleanups, prep for PCI hotplug API conversion

- Reduce uses of gdth_pci_str::pdev, preferring a local variable
  (or function arg) 'pdev' instead.

- Reduce uses of gdth_pcistr array, preferring local variable
  (or function arg) 'pcistr' instead.

- Eliminate lone use of gdth_pci_str::irq, using equivalent
  pdev->irq instead

- Eliminate assign-only gdth_pci_str::io_mm

Note:  If the indentation seems weird, that's because a line was
converted from spaces to tabs, when it was modified.

Subject: [SCSI] gdth: convert to PCI hotplug API

- remove PCI device sort, which greatly simplifies PCI probe,
  permitting direct, per-HBA function calls rather than an indirect
  route to the same end result.

- remove need for pcistr[]

Subject: [SCSI] ips: sg chaining support to the path to non I/O commands

I overlooked ips_scmd_buf_write and ips_scmd_buf_read when I converted
ips to use the data buffer accessors.

ips is unlikely to use sg chaining (especially in this path) since a)
this path is used only for non I/O commands (with little data
transfer), b) ips's sg_tablesize is set to just 17.

Thanks to Tim Pepper for testing this patch.

Subject: [SCSI] st: add option to use SILI in variable block reads

Add new option MT_ST_SILI to enable setting the SILI bit in reads in variable
block mode. If SILI is set, reading a block shorter than the byte count does
not result in CHECK CONDITION. The length of the block is determined using the
residual count from the HBA. Avoiding the REQUEST SENSE command for every
block speeds up some real applications considerably.

Subject: [SCSI] st: show options currently set in sysfs

Show the current binary tape driver and mode options is sysfs. A file
(options) is created in each directory in /sys/class/scsi_tape. The files
contain masks showing the options. The mask bit definitions are the same as
used when setting the options using the MTSETDRVBUFFER function in the
MTIOCTOP ioctl (defined in include/linux/mtio.h). For example:
> cat /sys/class/scsi_tape/nst0/options
0x00000d07

Subject: [SCSI] aacraid: READ_CAPACITY_16 shouldn't trust allocation length in
 cdb

When aacraid spoofs READ_CAPACITY_16, it assumes that the data length
in the sg list is equal to allocation length in cdb. But sg can put
any value in scb so the driver needs to check both the data length in
the sg list and allocation length in cdb.

If allocation length is larger than the response length that the
driver expects, it clears the data buffer in the sg list to zero but
it doesn't need to do. Just setting resid is fine.

Subject: [SCSI] ps3rom: Simplify fill_from_dev_buffer()

As we no longer need to calculate the data length of the whole scatterlist,
we can abort the loop earlier and coalesce req_len and act_len into one
variable, making fill_from_dev_buffer() more similar to fetch_to_dev_buffer().

The problem is that serveral drivers are sending a target reset from the
device reset handler, and if we have multiple devices a target reset gets
sent for each device when only one would be sufficient. And if we do a target
reset it affects all the commands on the target so the device reset handler
code only cleaning up one devices's commands makes programming the driver a
little more difficult than it should be.

This patch adds a target reset handler, which drivers can use to send
a target reset. If successful it cleans up the commands for a devices
accessed through that starget.

Subject: [SCSI] zfcp: convert zfcp to use target reset and device reset
 handler

[based on proposal from Mike Christie <michaelc@cs.wisc.edu>, this
patch adds some simplifications to the handler functions]

With the new target reset handler callback in the SCSI midlayer, the
device reset handler in zfcp can be split in two parts. Now, zfcp does
not have to track anymore whether the device supports LUN resets, so
remove this flag and let the SCSI midlayer decide what to do.

The device reset handler simply issues a LUN reset and the target
reset handler a target reset.

Subject: [SCSI] zfcp: Fix handling for boxed port after physical close

When a FSF physical close returns the status boxed, this means that
another system already closed the port. For our system this is the
same status as in the good path, we have to send the normal close. So,
set the status for the boxed response to the same as for the good
status.

Subject: [SCSI] BusLogic: make FlashPoint support x86-32 only

We've verified that there are 64 bit and endianness problems in the
flashpoint driver.  Reverse the logic of CONFIG_OMIT_FLASHPOINT (make
it CONFIG_SCSI_FLASHPOINT) and make it depend on X86_32 so it can't
appear for any other architectures.  Long term, if someone chooses,
they could make FlashPoint 64 bit compliant (it looks like its a
question of fixing up the sizes in some of the packed descriptors)

Subject: [SCSI] block: add sg buffer copy helper functions

This patch adds new three helper functions to copy data between an SG
list and a linear buffer.

- sg_copy_from_buffer copies data from linear buffer to an SG list

- sg_copy_to_buffer copies data from an SG list to a linear buffer

When the APIs copy data from a linear buffer to an SG list,
flush_kernel_dcache_page is called. It's not necessary for everyone
but it's a no-op on most architectures and in general the API is not
used in performance critical path.

Subject: [SCSI] scsi: add wrapper functions for sg buffer copy helper
 functions

LLDs need to copies data between the SG table in struct scsi_cmnd and
liner buffer. So they use the helper functions like

sg_copy_from_buffer(scsi_sglist(sc), scsi_sg_count(sc), buf, buflen)
sg_copy_to_buffer(scsi_sglist(sc), scsi_sg_count(sc), buf, buflen)

This patch just adds wrapper functions:

scsi_sg_copy_from_buffer(sc, buf, buflen)
scsi_sg_copy_to_buffer(sc, buf, buflen)

Subject: [SCSI] consolidate command allocation in a single place

Since the way we allocate commands with a separate sense buffer is
getting complicated, we should isolate setup and teardown to a single
routine so that if it gets even more complex, there's only one place
in the code that needs to be altered.

Subject: [SCSI] scsi_debug: create new scsi_debug devices at a single place

Two functions, sdebug_add_adapter and devInfoReg, creates new
scsi_debug devices. To simplify the code, this patch adds a new helper
function to create new scsi_debug devices (sdebug_device_create) and
converts both functions to use it.

I plan to add more to scsi_debug devices (e.g. using a thread for a
scsi_debug device for scalability testings). This patch enable me to
add such to just the new helper function instead of touching two
functions, sdebug_add_adapter and devInfoReg.

Subject: [SCSI] scsi_debug: remove unnecessary function declarations

This patch removes lots of function declarations with moving

to silence checkpatch.pl

Subject: [SCSI] aic7xxx: Test opcode, not definition in aicasm:type_check()

This fixes a bug that we treat all sequencer operations as ands and
never do the additional invalid bit checks non-and operations require
because the if () to determine this has an operand which is always
true at the end of the or statement.

Subject: [SCSI] qla4xxx: fix scsi command completion, lun reset and target
 reset code

This patch contains the following:

1. when hba completion status is good, check for iscsi transport
   errors (underflow/overflow) prior to checking the scsi status

2. New firmware requires that one marker iocb be issued for each task
   management command. The patch issues marker iocb immediately
   following a LUN or Target reset.

Subject: [SCSI] mptsas: do not use ioc->handle to locate hba portinfo
 structure

While performing hardware raid reset testing via the raid's client, I
noticed that sometimes, following the reset, that there would be more
raid targets in the lsscsi output than there actually were raid
targets.  I tracked this down to the following issue.

Fusion cannot always find the mptsas_portinfo structure for the hba
because it uses the handle stored in ioc->handle to locate it.  The
problem is that the firmware can change the handle associated with the
hba when h/w raid is reset (via the raid client).  When this happens,
the driver will allocate another mptsas_portinfo structure and link it
into the chain of said structures.  This ultimately causes confusion
within the driver resulting in targets not being removed when they
should be.

Eric Moore pointed out that the hba's portinfo structure is always the
first structure on the sas_topology list.  This patch modifies
mptsas.c to access the hba's portinfo structure by taking the first
structure on said list.

Subject: [SCSI] WD33C93: let platform stub override no_sync/fast/dma_mode

SGI machines with WD33C93 allow usage of burst mode DMA, which increases
performance noticable. To make this selectable by the sgiwd93 stub,
setting the values for no_sync, fast and dma_mode has been moved to the
individual platform stubs.

There's a problem with the combination of the upstream power

suspend path still uses the global variable.  Convert it to check
ioc->msi_enable.

Subject: [SCSI] zfcp: Add qtcb dump to hba debug trace

This patch adds per request hardware debugging data to the trace
record which is written per request. It's a replacement for some sad
kernel message based debugging code. Considering the amount of trace
data, printk() is not suitable for this stuff. Writing binary traces
is more efficient. In addition we got all information in one place.

The QTCB trace data is only dumped for requests other than SCSI
requests.  Otherwise we would flood the trace ring buffer. We are
mostly interested in non-SCSI, recovery related requests here anyway.

This patch also works around a known hardware bug. It truncates QTCB
traces so that we do not save unused areas of the hardware trace.

Subject: [SCSI] zfcp: Add traces for state changes.

This patch writes a trace record which provides information about state
changes for adapters, ports and units, e.g. target failure, targets becoming
online, targets being temporarily blocked due to pending recovery, targets
which have been recovered successfully etc.

From 9467a9b3efdd9041202f71cc270bda827a7ec777 Mon Sep 17 00:00:00 2001
From: Martin Peschke <mp3@de.ibm.com>
Date: Thu, 27 Mar 2008 14:22:03 +0100
Subject: [SCSI] zfcp: Trace all triggers of error recovery activity

This patch allows any recovery event to be traced back to an exact
cause, e.g. a particular request identified by an id (address).

Subject: [SCSI] zfcp: Add trace records for recovery actions.

This patch writes trace records for various phases of a recovery action:
action being created, action being processed, action continueing
asynchronously, action gone, action timed out, action dismissed etc.

with:
	leX_add_cpu(&little_endian_variable, expression_in_cpu_byteorder);
generated with semantic patch

Subject: [SCSI] wd33c93: fix up cut and paste error

The three drivers: a2091, gvp11 and mvme147 have erroneous references
to a3000_host.  Fix these to be references to the proper host
variable.

Subject: [SCSI] hptiop: fix header.context usage

header.context is a 64 bit field, but it's deliberately split into
context and context_hi32.  Thus cpu_to_le64 assignments are wrong on
this.  Replace them with the correct settings of both the low and high
words.

From 81e56ded878aeb8730f18c1d0a70d5face788be3 Mon Sep 17 00:00:00 2001
From: Adrian Bunk <bunk@kernel.org>

Subject: [SCSI] aic94xx: cleanups

- static functions in .c files shouldn't be marked inline
- make needlessly global code static
- remove the unused aic94xx_seq.c:asd_unpause_lseq()
- #if 0 other unused code

[akpm@linux-foundation.org: coding-style fixes]

Subject: [SCSI] zfcp: simplify zfcp_dbf_timestamp()

Change zfcp_dbf_timestamp() so that it just calculates timespec from
timestamp. First step to be able to rip this code out of zfcp.
Besides, this change makes it easier to rip out old-style debug view
functions.

From: Martin Peschke <mp3@de.ibm.com>
Date: Mon, 31 Mar 2008 11:15:29 +0200
Subject: [SCSI] zfcp: Shorten excessive names in debug trace.

Saving on line breaks, improving readability, by shortening excessive
function names and identifiers, by simplifying some functions call
chains, and by simplifying nesting of some data structure.

Subject: [SCSI] fix barrier failure issue

Currently, if the barrier command fails, the error return isn't seen
by the block layer and it proceeds on regardless.  The problem is that
SCSI always returns no error for REQ_TYPE_BLOCK_PC ... it expects the
submitter to pick the errors out of req->errors, which the block
barrier functions don't do.

Since it appears that the way SG_IO and scsi_execute_request() work
they discard the block error return and always use req->errors, the
best fix for this is to have the SCSI layer return an error to block
if one actually occurred (this also allows us to filter out spurious
errors, like deferred sense).

This patch is a bug fix that will need backporting to stable, but it's
also quite a big change and in need of testing, so we'll incubate in
the main kernel tree and backport at the -rc2 or so stage if no
problems turn up.

Subject: [SCSI] transport_class: BUG if we can't release the attribute
 container

Every current transport class calls transport_container_release but
ignores the return value.  This is catastrophic if it returns an error
because the containers are part of a global list and the next action of
almost every transport class is to free the memory used by the
container.

Fix this by making transport_container_release a void, but making it BUG
if attribute_container_release returns an error ... this catches the
root cause of a system panic much earlier.  If we don't do this, we get
an eventual BUG when the attribute container list notices the corruption
caused by the freed memory it's still referencing.

Also made attribute_container_release __must_check as a reminder.

Subject: [SCSI] ips: remove spurious cpu_to_leX on outX statements

These are completely wrong because both outX and writeX do an
automatic reverse of their arguments if necessary, so having an extra
cpu_to_leX gives us the wrong ordering on BE platforms again.

Subject: [SCSI] qla2xxx: Simplify interrupt handler locking.

There's no need to use the heavier (albiet safer)
*_irq[save|restore]() locking primitives within the driver's
interrupt handlers, interrupts are guaranteed to be
non-reentrant.  Use lightweight spin_lock() and spin_unlock()
primitives while acquiring the hardware_lock.

Subject: [SCSI] qla2xxx: Add FC-transport Asynchronous Event Notification
 support.

Supported events include LIP, LIP reset, RSCN, link up, and link
down.

To support AEN (and additional forthcoming features), we also
introduce a simple deferred-work construct to manage events which
require a non-atomic sleeping-capable context.  This work-list is
processed as part of the driver's standard DPC routine.

Subject: [SCSI] qla2xxx: Add hardware trace-logging support.

Recent ISPs have a region within FLASH which acts as a repository
for the logging of serious hardware and software failures.
Currently, the region is large enough to support up to 255
entries.

From 587f4cae4a8ce1315c3def2229c2a912637269b6 Mon Sep 17 00:00:00 2001
From: Andrew Vasquez <andrew.vasquez@qlogic.com>
Date: Thu, 3 Apr 2008 13:13:20 -0700
Subject: [SCSI] qla2xxx: Cruft cleanup of functions and structures.

Strip unused (DEBUG-ONLY) enabled functions, inlines, useless
wrappers, and unused DPC flags from the code.  Another step in
the migration towards a cleaner (less-crusty) driver.

Subject: [SCSI] qla2xxx: Add Flash Descriptor Table layout support.

The Flash Descriptor Table (FDT) present on many recent HBAs
encodes flash accessing characteristics of the flash-part used on
the HBA.  Use this information during flash manipulation (writes)
rather than using specific hard-coded values based on queried
manufacturer and device IDs.

Subject: [SCSI] qla2xxx: Check alternate 'reason' code during GPSC status
 handling.

Some switches return 0x09 (Command not supported) as the reason
code for GPSC failure.  Check for this code, and disable
additional GPSC queries if found.

Subject: [SCSI] qla2xxx: Add midlayer target/device reset support.

Now that infrastructure is present within the midlayer and there
is a clear distinction between what is expected from a device and
target reset, convert the current device-reset codes to a
target-reset, and add codes to perform a proper device-reset (LUN
reset).

In the process of adding reset support, collapse and consolidate
large sections of mailbox-command (TMF issuance) codes,
generalize the two 'wait-for-commands-to-complete' functions, and
add a generic-reset routine for use by midlayer reset functions.

Subject: [SCSI] qla2xxx: Check DFLG_NO_CABLE only on physical port.

As there is no actual cable connection on vports, made change so
that the driver checks DFLG_NO_CABLE against ha->device_flags
only for physical port.

Subject: [SCSI] qla2xxx: Use proper HA during asynchrounous event handling.

Changes are added to the driver so that it can behave properly
upon having asynchronous events, for example, addition of target
devices to the VPs.

Subject: [SCSI] qla2xxx: Correct vport configuration-change handling.

Upon having configuration changes on vports only, the driver
handles SCR regardless physical port state and, in turn, it
results mailbox error as below:

	Mar 20 11:24:20 dl585 kernel: qla2x00_mailbox_command(9): **** FAILED.  mbx0=4005, mbx1=1, mbx2=8100, cmd=70 ****

With the changes, driver checks physical port loop_state and make
sure the port is ready to take commands.

Subject: [SCSI] lpfc 8.2.6 : Multiple discovery fixes

Multiple Discovery Fixes:
- Fix race on discovery due to link events coinciding with vport_delete.
- Use NLP_FABRIC state to filter out switch-based pseudo initiators that
   reuse the same WWNs.
- Correct erroneous setting of DID=0 in lpfc_matchdid()
- Correct extra reference count that was in the lookup path for the
  remoteid from an unsolicited ELS.
- Correct double-free bug in els abort path.
- Correct FDMI server discovery logic for switch that return a WWN of 0.
- Fix bugs in ndlp mgmt when a node changes address
- Correct bug that did not delete RSCNs for vports upon link transitions
- Fix "0216 Link event during NS query" error which pops up when vports
  are swapped to different switch ports.
- Add sanity checks on ndlp structures
- Fix devloss log message to dump WWN correctly
- Hold off mgmt commands that were interferring with discovery mailbox cmds
- Remove unnecessary FC_ESTABLISH_LINK logic.
- Correct some race conditions in the worker thread, resulting in devloss:
  - Clear the work_port_events field before handling the work port events
  - Clear the deferred ring event before handling a deferred ring event
  - Hold the hba lock when waking up the work thread
  - Send an acc for the rscn even when we aren't going to handle it
- Fix locking behavior that was not properly protecting the ACTIVE flag,
  thus allowing mailbox command order to shift.

Subject: [SCSI] lpfc 8.2.6 : PCI Parity and EEH handling fixes

PCI Parity and EEH handling Fixes:
- Under a PCI Data Parity Error, remove a completion routine callback that
  was on a command that we had already failed and released.
- Under PCI parity error, we were not reinstalling the interrupt handler
  in the slot_reset callback, so we never became functional again.

Subject: [SCSI] lpfc 8.2.6 : Miscellaneous Fixes

Miscellaneous Fixes
- Allow WRITE_VPARAM command when the virtual port is in a stopped state
- Fixed handling of our queue depth max that was unconditionally raising
  the depth on all vports, rather than just the vport affected.
- Fix race in interrupt handler for mailbox processing that did not take
  out the host lock.
- Removed unused functions: find_node, findnode_rpi, and fabric_abort_flogi
- Correct misspelled word unsolicited in message 0146
- Correct HW-error 5 handling - it should not reset the adapter
- Correct handling of IOCBs, which did not null out our pCmd field before
  invoking the midlayer io done function.
- Changed our maximum supported target id to 4096

Subject: [SCSI] initio: fix big endian problems for auto request sense

Most of the cpu_to_le32() usage was wrong in one way or another.
Compiler warning on BE builds was just the tip of the iceberg.
This patch attempts to make this driver work on BE though I
don't have the HW to test it.

Subject: [SCSI] bsg: takes a ref to struct device in fops->open

bsg_register_queue() takes a ref to struct device that a caller
passes. For example, bsg takes a ref to the sdev_gendev for scsi
devices. However, bsg doesn't inrease the refcount in fops->open. So
while an application opens a bsg device, the scsi device that the bsg
device holds can go away (bsg also takes a ref to a queue, but it
doesn't prevent the device from going away).

With this patch, bsg increases the refcount of struct device in
fops->open and decreases it in fops->release.

In the case the unit is blocked, zfcp_unit_get has not been called
yet, so the error handling path should not call zfcp_unit_put.

Subject: [SCSI] iscsi: bidi support at the generic libiscsi level

- prepare the additional bidi_read rlength header.
- access the right scsi_in() and/or scsi_out() side of things.
  also for resid.
- Handle BIDI underflow overflow from target
