  vdisk_blockio: Report invalid scatterlists
  
  It is possible for a target driver to pass a scatterlist via
  scst_cmd_set_tgt_sg() that is valid for the vdisk_fileio handler
  but not for the vdisk_blockio handler. Complain loudly if an invalid
  scatterlist is passed to vdisk_blockio because such scatterlists
  cause silent data corruption with most Linux block drivers.

  vfs_read() and vfs_write().

  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

  ./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).

  fix (no IO errors, all the files are properly written to the directory).

  scst: Rework SCSI pass-through support for kernel versions >= 2.6.30
  
  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: 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.

  scst_vdisk: Remove a superfluous cast
  
  The 'iov_base' member of 'struct iovec' is declared in
  <uapi/linux/uio.h> with type 'void __user *'. Adding an integer
  to a void pointer has the same effect as adding an integer to
  a char pointer in the C language. This means that it is safe to
  remove the cast in front of the eiv->iov_base pointer.
  
  Please note that a similar construct already exists in the iSCSI
  target driver. From the nthread.c source file:
  
  			iop->iov_base += rest;
  			iop->iov_len -= rest;
  
  This patch does not change any functionality.

  scst_vdisk: Reduce number of casts
  
  Since 'address' points at kernel space memory, change its type
  from uint8_t __user * into uint8_t *. This change reduces the
  number of casts between uint8_t __user * to uint8_t * in
  fileio_exec_write().

  scst, iscsi-scst: Add thread_pid attribute
  
  For SCST devices with a short name determining which SCST command
  threads serve a given LUN requires an (expensive) walk of the
  process table. For SCST devices with a long name it is not possible
  to determine unambiguously which command threads serve a given
  LUN. Hence add a thread_pid sysfs attribute that makes it easy to
  figure out which command threads serve a LUN.

  scst_mem: Fix a memory leak triggered by the scst_user driver
  
  Avoid that the following memory leak can occur:
  - sgv_pool_alloc() is called with SGV_POOL_RETURN_OBJ_ON_ALLOC_FAIL
    set, with neither SGV_POOL_NO_ALLOC_ON_CACHE_MISS nor
    SGV_POOL_ALLOC_NO_CACHED set and with 'size' such that
    sgv_max_local_pages < pages_to_alloc <= pool->max_cached_pages.
  - sgv_get_obj() and sgv_alloc_arrays() succeed.
  - sgv_alloc_sg_entries() fails.
  - sgv_get_obj() returns the SGV object with no buffers.
  - A call to sgv_pool_free() adds this object to the recycle list.
  - sgv_pool_alloc() is called a second time with the same parameters.
  - sgv_get_obj() retrieves the object that was previously added to
    the recycle list.
  - sgv_alloc_arrays() is called and overwrites the obj->sg_entries
    pointer although it still points at allocated memory, resulting
    in a memory leak.

  scst_local: Change max_lun into SCST_MAX_LUN (16383)
  
  Today SCST does not support LUN numbers >= 16384. Additionally,
  there is a bug in older Linux initiator systems that prevents
  proper handling of LUN numbers >= 2**32. See also Hannes Reinecke,
  scsi_scan: Fixup scsilun_to_int(), June 25, 2014 (commit ID
  d9e5d6183715e691b37afd3785c311d05cd1338d). Hence set max_lun to

  vdisk_blockio: Make large COMPARE AND WRITE requests work for stacked block devices
      
  Stacked block devices impose weird restrictions on S/G-lists. Hence
  make the COMPARE AND WRITE implementation independent of these
  restrictions.
      
  Additionally, reduce the MAXIMUM COMPARE AND WRITE LENGTH limit from
  0xff (no limit) to 0xfe to reduce the maximum amount of memory allocated
  during a COMPARE AND WRITE. Also serialize COMPARE AND WRITE
  operations, fix the offset reported for miscompares and fix the start
  offset of the region that is synchronized if the FUA bit has been set.

  scst_lib: Fix READ POSITION parsing
  
  For code 08h (EXTENDED FORM) minimal response length is 32, see table
  "READ POSITION data format, extended form". In SSC-[2,3] table "READ
  POSITION service action codes" requests minimum response lenght 28
  bytes, but it is an apparent typo, because the actual data format is 32
  bytes long. In SSC-4 it is fixed.

  cmd->state check without holding the command list lock. Hence move the
  perform the cmd->state check without holding the command list lock.

  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().

  Retry sending XFER_RDY, data and response frames if the network

  failed for another reason, report this to the initiator as a
  write error (ASC = 03; ASCQ = 00 which stands for PERIPHERAL
  DEVICE WRITE FAULT). If sending a response frame failed with
  another error code than -ENOMEM, do not send a response.
