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.

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 #

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: 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.

For SCST devices with a short name determining which SCST command

to determine unambiguously which command threads serve a given
LUN. Hence add a thread_pid sysfs attribute that makes it easy to

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.

scst: Make access control group removal behavior configurable
SCST rejects removal of an access control group with one or more
sessions with error code -EBUSY. Make it easy to change this
behavior into forcibly closing sessions when an access control
group is removed.

Change BUG_ON(1) into BUG()
With CONFIG_BUG=y both BUG() and BUG_ON(1) halt the system. However,
with CONFIG_BUG=n BUG() halts the system but BUG_ON(1) not. To avoid
such subtleties, change BUG_ON(1) into BUG().

Instead of waiting for TIMEDWAIT event when disconnecting and blocking,

and only perform the actual rdma_disconnect upon disconnect request.
Note that rdma_disconnect can not be called from atomic context, so need
