scst: Switch from the cpu_*() to the cpumask_*() API
The cpus_*() functions were deprecated via patch "cpumask:
introduce new API, without changing anything" (November 2008,
commit ID 2d3854a37e8b). Hence switch from the cpus_*() API to
the cpumask_*() API.
This patch has the intended side effect of not adding the "[key]"
property to cpumask sysfs attributes that contain the default
cpumask. The current code namely reads uninitialized bits on
systems where nr_cpu_ids < NR_CPUS because cpus_equal() compares
more bits than those that were set by cpumask_copy().

Hush Coverity warning of scst_ws_push_single_write() uninitialized pointer
Coverity warns that sgv may be used uninitialized. The warning
applies to WRITE SAME commands with LBDATA == PBDATA == 0 (replicate
a single block of user data into the specified LBA range).
The warning appears to be spurious - when LBDATA == PBDATA == 0,
scst_ws_write_cmd_finished() will not use the uninitialized value
saved by scst_ws_push_single_write().
Move initialization of sgv earlier in the function to quiesce the warning.

scst_user, rt: Wake command processing thread when needed
In a fully-preemptible realtime kernel (CONFIG_PREEMPT_RT_FULL=y),
SCSI commands from an initiator time out because the userland target
application is never woken to process them.
This is because in a fully-preemptible realtime kernel, soft-IRQ
(tasklet) execution always occurs in a ksoftirqd thread and
preempt_count is not manipulated on soft-IRQ processing entry/exit.
This makes in_interrupt() useless for determining whether soft-IRQ
processing is occurring; instead, in_serving_softirq() should be
used for that purpose.

Fix spurious BUG when parse_type != SCST_USER_PARSE_STANDARD
Changeset 4224 introduced EXTRACHECKS for valid lba/data_len and state
at the end of the parsing phase of command processing.
However, the checks do not account for deferral of parsing to userland,
as occurs when SCST_USER_PARSE_CALL or SCST_USER_PARSE_EXCEPTION are specified.
In such cases the checks report errors on commands that userland has not yet
had an opportunity to parse.
NOTE: this includes a refactoring of the EXTRACHECKS to improve clarity.
The rework is not exactly equivalent to the original code, but does
conform to the comments describing the original code.
Specifically, the original code would not trap an illegal command state
unless there was also an illegal lba or data_len.

Makefiles: calculate KVER properly
When deriving the kernel version (KVER) from KDIR, the file
$(KDIR)/include/config/kernel.release should be preferred over
'make kernelversion'.
For example, the Ubuntu 3.2.0-23-generic kernel has a kernel.release
file containing '3.2.0-23-generic', but 'make kernelversion' returns
3.2.14. Since the modules are stored under /lib/modules/3.2.0-23-generic,
the value in kernel.release is the correct one to use.
Also:
- Evaluate KVER only once
- All depmod commands must include KVER

scst, qla2x00t: Prevent inappropriate sleeping with a real-time kernel
With a realtime kernel with full preemption (CONFIG_PREEMPT_RT_FULL),
spinlocks can sleep, interrupt handlers run in thread context, and
the standard local_irq functions manipulate preemptibility, not HW
interruptibility. Under these conditions, most calls to local_irq
functions should be replaced by no-ops. The CONFIG_PREEMPT_RT patch
defines _nort versions of local_irq functions that compile away
under CONFIG_PREEMPT_RT_FULL and compile to their "normal"
equivalents otherwise.
Define _nort equivalents to support compilation against both
"normal" and RT-patched kernels, and use the _nort local_irq
functons in cases where spinlocks are taken within a
local_irq_save() or local_irq_disable() block. Without these
changes, runtime warnings about "sleeping function called from
invalid context" occur.

Currently the install location of SCST is pretty much hard coded into
the Makefiles to be /usr/local.
I am custom building a system for ZFS & SCST and I want to install in
/usr instead of /usr/local.
Currently I am doing a “find . -name Makefile -exec sed -i 's:/usr/local:/usr:g'
{} \;” to accommodate this.
This patch fixes it.

While writing DKMS support for the SCST and iSCST-SCST kernel modules, I ran
into a (common) problem with regard to out-of-tree build detection. A common
method to detect out-of-tree building is by using the KERNELRELEASE variable.
The usage of this variable poses a problem when using DKMS. DKMS itself uses
the KERNELRELEASE variable to specify the kernel for which the driver to
build. A suggested alternative would to use the PATCHLEVEL variable as part
of the detection mechanism instead. I attached a patch reflecting this
suggested change.

an external module. When applying the SCST kernel patch to the mainstream
kernel tree with debugging and/or tracing enabled however, the resulting code
triggers a compiler error. This is because the symbols DEBUG and TRACING
conflict with symbols with the same named defined in unrelated kernel headers.
The patch below resolves these conflicts by renaming the following preprocessor
symbols:
- DEBUG into CONFIG_SCST_DEBUG.
- DEBUG_DIGEST_FAILURES into CONFIG_SCST_ISCSI_DEBUG_DIGEST_FAILURES.
- DEBUG_OOM into CONFIG_SCST_DEBUG_OOM.
- DEBUG_RETRY into CONFIG_SCST_DEBUG_RETRY.
- DEBUG_SN into CONFIG_SCST_DEBUG_SN.
- DEBUG_TM into CONFIG_SCST_DEBUG_TM.
- EXTRACHECKS into CONFIG_SCST_EXTRACHECKS.
- SCST_HIGHMEM into CONFIG_SCST_HIGHMEM.
- STRICT_SERIALIZING into CONFIG_SCST_STRICT_SERIALIZING.
- TM_DBG_GO_OFFLINE into CONFIG_SCST_TM_DBG_GO_OFFLINE. Mapped 0/1 values
into macro undefined / macro defined.
- TRACING into CONFIG_SCST_TRACING.
- USE_EXPECTED_VALUES into CONFIG_SCST_USE_EXPECTED_VALUES.
- In qla_isp/linux/isp_scst.c, renamed DEBUG into DEBUG_ISP_SCST.
- In qla_isp/..., renamed SCSI_TARGET in SCST_SCSI_TARGET.
- In qla_isp/..., renamed SCSI_TARGET_DEV in SCST_SCSI_TARGET_DEV.
Additionally, all CONFIG_SCSI_TARGET* macro's are renamed into CONFIG_SCST* in
order to avoid confusion between the STGT CONFIG-symbols and the SCST CONFIG-
symbols.
The following additional options are now configurable through Kconfig:
- CONFIG_SCST_ISCSI_DEBUG_DIGEST_FAILURES
- CONFIG_SCST_STRICT_SERIALIZING
- CONFIG_SCST_STRICT_SECURITY
- CONFIG_SCST_ALLOW_PASSTHROUGH_IO_SUBMIT_IN_SIRQ
- CONFIG_SCST_ABORT_CONSIDER_FINISHED_TASKS_AS_NOT_EXISTING
- CONFIG_SCST_USE_EXPECTED_VALUES
- CONFIG_SCST_DEBUG_OOM
- CONFIG_SCST_DEBUG_RETRY
- CONFIG_SCST_DEBUG_SN
- CONFIG_SCST_DEBUG_TM

The patch below has been verified as follows:
- Verified that the following command does not print any new warning messages:

- Verified as follows that the internal SCST patches still apply cleanly:
for p in *patch; do patch -p0 --dry-run -f -s <$p; done
- Checked that the patch generated by generate-kernel-patch still applies
cleanly to the 2.6.25.7 kernel, and that the patched kernel tree still
compiles, installs and boots fine, that the iscsi-scst, ib_srpt,
scst_disk and scst_vdisk modules still load, and that iSCSI communication
still works fine. All SCST kernel configuration options that could be
enabled have been enabled during this test.

- Verified that make -s clean && make -s iscsi scst && make -s -C srpt
still works and does not trigger any new compiler warnings.
- Checked that the patch generated by generate-kernel-patch still applies
cleanly to the 2.6.25.4 kernel, and that the patched kernel tree still
compiles, installs and boots fine, and that the iscsi-scst, ib_srpt,
scst_disk and scst_vdisk modules still load.
Note: I'm not sure any of the above verifications did trigger the code paths
changed by this patch.

I've updated the MPT fusion target driver for LSI SCSI/FC/SAS HBAs. The original SCST MPT driver was based on the 1.00.13 LSI
sample target driver. LSI has since released version 1.00.14 of the sample target driver. I've ported all the changes from .13 to
.14 into the SCST MPT driver for consistency. I've also updated the SCST MPT driver to compile under 2.6.24 and 2.6.25.4. Finally,
I force the SCSI parallel transfer rate to very slow depending on the SCSI HBA firmware revision. Newer versions of SCSI HBA
firmware have a bug where the incorrect amount of data is transferred for non-divisible-by-4 length transfers (like standard 14 byte
REQUEST SENSE). LSI is aware of the problem and I'll update the driver to restore functionality upon a new good SCSI HBA firmware
release.
I still have not confirmed operation with LSI SAS or FC HBAs.

The patch below implements the following changes:
- Fixes the remaining warnings reported by checkpatch.pl with regard to the use
of whitespace in C code.
- Adds double qoutes around some #warning messages, such that checkpatch.pl
does no longer try to interprete the text behind the #warning preprocessor
directive.
- Adds an extra conversion to the generate-kernel-patch script that removes
the single space from before goto-labels while generating the kernel patch.
This patch has been tested as follows:
- Verified that svn diff -x -w only shows changes in the #warning preprocessor directives.
- Verified the output of svn diff by reading it.
- Verified that checkpatch.pl does no longer complain on the use of whitespace
(searched through the checkpatch.pl output for the text ' space').
- Verified that the patch generated by the generate-kernel-patch script still
applies cleanly to the 2.6.24 kernel, and that the patched kernel still compiles cleanly.
Please let me know if I have to resubmit parts of this patch to other SCST authors.

One of the Linux kernel patch submission requirements is that source files do
not contain trailing whitespace. The patch below removes trailing whitespace
from .c and .h source files.
Note: it might be more convenient to run the script I used to generate this
patch than to review and apply the patch below. This is how I generated and
verified the patch below:
cat <<EOF >./strip-trailing-whitespace
#!/bin/bash
trap "rm -f $t" EXIT
t=/tmp/temporary-file.$$
for f in "$@"
do
sed 's/[ ]*$//' <"$f" >"$t" && mv "$t" "$f"
done
EOF
chmod a+x ./strip-trailing-whitespace
find -name '*.[ch]' | xargs ./strip-trailing-whitespace
svn diff -x -w

- "RECEIVE DIAGNOSTIC RESULTS" command handling fixed
- Obtaining device queue parameters in scst_obtain_device_parameters() changed to handle NOT READY sense
- Fixed possible dev_cmd_count underflow
- Minor iSCSI-SCST connection closing cleanups and fixes
- Semantic of other *_atomic flags changed a bit. Now they are intended only to allow SCST to optimize execution context. The corresponing functions now can *always* be called on atomic context and, if necessary, should manually determine that using scst_cmd_atomic() function and restart using corresponding *_NEED_THREAD_* return value.
- scst_cmd_get_tgt_resp_flags() and SCST_TSC_FLAG_STATUS flag made obsolete and replaced by scst_cmd_get_is_send_status(). All in-tree drivers updated accordingly
- Cleanup: preprocessing_done_atomic removed, now preprocessing_done() callback always called on thread context
- 64-bit cleanups
- Documented that iscsi-scst-adm is currently broken and explained why
- In user space Makefile's added possibility to specify external linker flags
- Minor performance optimizations
- Other minor cleanups

- Important reference counting and barriers usage cleanups
- Sense buffer made dynamic
- Other minor improvements and cleanups
- Docs updates

Particularly:
- Added ability for target drivers to set result of command's status delvery to initiator (see scst_set_delivery_status())
- Added ability for user space devices set some mode page parameters to make SCST core behave correspondingly
- TM improvements
- Few possible crashes fixed
- Logging improvements
- Performance improvements
- Docs updates

* Allows LSI MPT target driver to compile on kernels >2.6.15
* Changes the way how gettid() syscall gate implemented

This patch fixes a race condition where a pointer to the just-finished SCST command would interfere with the incoming target
command.
Also, printing out TargetStatusSendReq IOCStatus is now done in debug/tracing mode if we're a SCSI device and the expected "error" case for attempting to send simultaneous status and sense is triggered.

- corrects the amount of data transferred when cached sense data is used to satisfy a REQUEST SENSE command.
- removes support for non scatterlist buffers in scst_cmd (sg_cnt == 0).
