Bart Van Assche 904b3c1eb3 iscsi-scst: Kernel 3.19 build fix 
Change the data type of iscsi_conn.read_iov into struct kvec * and
switch from iscsi_conn.read_size to iscsi_conn.read_msg.count for
kernel version 3.19 and later. Cast the return type of
get_zeroed_page() to void * since with this patch the read_iov
data type depends on the kernel version. Remove the (void __force
__user *) casts when assigning to iov_base since for a kvec iov_base
is a kernel pointer instead of a user space pointer. Switch to
iov_iter_kvec() to initialize conn->read_msg.msg_iter.

  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.

  pread64() and pwrite64() system calls for examples of code that uses
  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).

  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().

  Fix Coverity warning of q2t_ctio_to_cmd() dead code
  
  Coverity warns that 'handle == Q2T_SKIP_HANDLE' can never occur, because
  code preceding the test has masked out a handle bit that would be
  required for the test to succeed.
  
  Fix that by extending Q2T_SKIP_HANDLE to incorporate
  CTIO_INTERMEDIATE_HANDLE_MARK as well.

  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().

  fcst: Handle frame send failures properly
  
  Retry sending XFER_RDY, data and response frames if the network
  driver reports that sending failed (-ENOMEM) instead of reporting
  a kernel warning (WARN_ON(1)). If sending XFER_RDY or data frames
  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.

Vladislav Bolkhovitin 97167af582 scst: Make lockdep_assert_held() easier to use 
The lockdep_assert_held() macro is a convenient debugging tool.
However, it is inconvenient to surround each invocation of that
macro by an #ifdef/#endif pair. Hence make it easier to use this
macro with older kernel versions.

Vladislav Bolkhovitin 13ee8e1649 We were setting the next timeout check to be the current time plus 
the timeout value. The problem is that if commands were started at
00:00:05 and 00:00:10 and the timeout value was 15 seconds and the
first command completed ok, then conn_rsp_timer_fn would have run
at 00:00:20 and rescheduled the next conn_rsp_timer_fn run for 15
secs from that time (00:00:35). But, we would have wanted to check on
the second command at 15 secs after its write_start time which is
00:00:25.

This patch has us reschedule the next conn_rsp_timer_fn run for
the req's write_start time + its timeout.

Vladislav Bolkhovitin 1f4f117f3f This patch fixes 2 issues. 
1. If we have a nop in flight then we do not really need to send
more to test if the other side is still there. Either that nop
will timeout and conn will be dropped or it will complete
and last_rcv_time will be updated.

2. We are sending nop-ins every nop_in_interval seconds, but if
we got a data half way in to the window, then when conn_nop_in_delayed_work_fn
is run it was scheduling the next check to be nop_in_interval more
seconds. With the current settings this could end up with us waiting
59 secs before sending a nop and about 130 secs for it to timeout, when
at 61 it should be timing out and getting cleaned up already. This patch
has us take into account when the last time we got data to try and
reschedule the next nop check closer to nop_in_interval from that time.
