scatterlist is passed to vdisk_blockio because such scatterlists

qla2x00t: Copy entire SCST sense buffer to q2x ctio
There seems to be a bug in passing sense information to QLA HBAs, where
the last 2 bytes of the sense data (ASC, ASCQ) are not copied to the low
level sense buffer.
We encountered this in ESX, which relies on these 2 bytes to parse the
MISCOMPARE sense code (0xE1, 0x1D, 0x00).
Bellow is a simple test to recreate this issue, but during vMotion
operations (where VMs are moved from one host to another), this may
cause the operation to fail leaving the VM in an inconsistent state.
The test I ran to verify that we are indeed missing the bytes is the
following:
1. Create a SCST based device
2. Expose the device to 2 ESX hosts
3. Format the device as VMFS5, create a test directory
4. From both hosts, I start writing to this directory (no VMs involved,
just write normal files)
At this stage, both ESX hosts try to take access to the directory.
The VMFS filesystem contains a per-directory lock which is managed by
COMPARE AND WRITE command.
Each ESX will attempt to change the VMFS lock location from unlocked to
locked to create the new file.
Obviously there are bound to be failures (which are equivalent to
programming locking conflicts), these are reported by the MISCOMPARE
sense code.
Upon these MISCOMPARE errors, the host will re-try taking the lock until
it succeeds, and will then proceed to perform the write operation on the
directory.
Due to the bug in copying the sense buffer from the SCST core to the QLA
ctio, instead of the full sense code, only the key (0xE) is sent, and
ESX does not know how to handle it resulting in IO error.
Here are the errors as they appear on the command line:
/vmfs/volumes/54a297c4-ca5af1cc-7f94-002219d20f28/ats_test #
./open_close_test-esx2.sh

./open_close_test-esx2.sh: line 8: can't create
ats_fileoptest-esx2_111.txt: Input/output error
In the /var/log/vmkernel.log, we can see that the sense information is
missing (0xE, 0x0, 0x0) instead of (0xE, 0x1D, 0x0).

Changes in this patch:
- Rework the SCSI pass-through code such that for kernel versions
>= 2.6.30 the scst_exec_req_fifo patch is no longer needed.
- Modify the pass-through code such that blk_rq_append_bio() is only
called for kernel version 2.6.30. For later kernel versions
blk_make_request() is called instead.
- Rework scst_scsi_exec_async().
- Add debug tracing of SCSI pass-through result status.
- Add a lockdep_assert_held() call in scsi_end_async().

[PATCH] scst_local: Fix bidirectional command support
scsi_setup_cmnd() sets sc_data_direction to DMA_TO_DEVICE for bidirectional
commands. Hence test SCpnt->request->next_rq instead of sc_data_direction
to figure out whether or not a command is bidirectional.

scst_vdisk: Micro-optimize vdisk_caching_pg
This patch does not change any behavior but micro-optimizes
vdisk_caching_pg(). Declaring the array caching_pg[] const reduces
11 bytes from the assembler code of this function.

scst_vdisk: Fix zero-copy read for tmpfs
For some filesystems, e.g. tmpfs, address_space.readpage is NULL.
Disable zero-copy reading for such filesystems. See also shmem_aops
in mm/shmem.c. See also inode_init_always() and empty_aops in fs/inode.c.
This patch avoids that the following call trace is triggered:

Overview ======== This is the SCST development repository. It contains not a single project SCST as one can think, but a number of them, which are divided as the following: 1. SCST core in scst/ subdirectory 2. Administration utility for SCST core scstadmin in scstadmin/ 3. Target drivers in own subdirectories qla2x00t/, iscsi-scst/, etc. 4. User space programs in usr/ subdirectory, like fileio_tgt. 5. Some various docs in doc/ subdirectory. Those subprojects are in most cases independent from each other, although some of them depend from the SCST core. They put in the single repository only to simplify their development, they are released independently. Thus, use "make all" only if you really need to build everything. Otherwise build only what you need, like for iSCSI-SCST: make scst scst_install iscsi iscsi_install For more information about each subproject see their README files. QLogic target driver ==================== QLogic target driver in qla2x00t/ is the old one, forked from qla2xxx from kernel 2.6.26. It is not maintained anymore and not built by default by the common Makefile targets, like "all". You can find the latest version of this driver in git://git.qlogic.com/scst-qla2xxx.git. It is now maintained by QLogic, hence located in the QLogic's git. To integrate it into the SCST build tree you need: 1. Clone the QLogic git tree somewhere in your system. 2. Create in the SCST root, i.e. this directory, a subdirectory with name qla2x00t_git 3. Symlink drivers/scsi/qla2xxx subdirectory in the cloned git tree to the qla2x00t_git subdirectory Thats all. Now "make all" and other common and QLA specific root Makefile targets "magically" start working. For detail instructions how to setup QLA target build environment see its README or HOWTO. You can still build the old driver using qla_old* root Makefile targets. Vladislav Bolkhovitin <vst@vlnb.net>, http://scst.sourceforge.net
