It seems some iSCSI targets (including the Linux kernel target) close
the TCP connection from the target side immediately after processing a
session logout.
When a TCP FIN comes in right after the iSCSI logout response,
iscsi_sw_sk_state_check sees the local socket as not yet being in
CLOSE_WAIT or CLOSE and logs an error. But the initiator would close
the connection right after processing the logout response anyway, and
the error is confusing to admins who just requested that the session be
shut down.
This adds a check of the session state, and suppresses the error if we
are in the process of logging out.

It makes no sense to flush the cache of a device without medium.
Errors during suspend must be handled according to their causes.
Errors due to missing media or unplugged devices must be ignored.
Errors due to devices being offlined must also be ignored.
The error returns must be modified so that the generic layer
understands them.

Somehow older areca firmware versions have issues with
scsi_get_vpd_page() and a large buffer, the firmware
seems to crash and the scsi error-handler will start endless
recovery retries.
Limiting the buf-size to 64-bytes fixes this issue with older
firmware versions (<1.49 for my controller).
Fixes a regression with areca controllers and older firmware versions

In the module initialization, invalid value for guard module parameter
is detected by the following check:
if (scsi_debug_guard > 1) {
printk(KERN_ERR "scsi_debug_init: guard must be 0 or 1\n");
return -EINVAL;
}
But this check isn't enough, because the type of scsi_debug_guard is
'int' and scsi_debug_guard could be a negative value.
This fixes it by changing the type of scsi_debug_guard to 'unsigned int'
instead of adding extra check for a negative value.

If data integrity support is enabled, prot_verify_write() is called in
response to WRITE commands and it verifies protection info from
prot_sglist by comparing against data sglist, and copies protection info
to dif_storep.
When multiple blocks are transfered by a WRITE command, it verifies and
copies these blocks one by one. So if it fails to verify protection
info in the middle of blocks, the actual data transfer to fake_storep
isn't proceeded at all although protection info for some blocks are
already copied to dif_storep. Therefore, it breaks the data integrity
between fake_storep and dif_storep.
This fixes it by ensuring that copying protection info to dif_storep is
done after all blocks are successfully verified. Reusing dif_copy_prot()
with supporting the opposite direction simplifies this fix.

If data integrity support is enabled, prot_verify_read() is called in
response to READ commands and it verifies protection info from dif_storep
by comparing against fake_storep, and copies protection info to
prot_sglist.
This factors out the portion of copying protection info into a separate
function. It will also be reused in the next change after supporting
the opposite direction (copying prot_sglist to dif_storep).

If the module parameter virtual_gb is greater than 0, the READ command
may request the blocks which exceed actual ramdisk storage (fake_storep).
prot_verify_read() should treat those blocks as wrap around the end of
fake_storep. But it actually causes fake_storep and dif_storep buffer
overruns.
This fixes these buffer overruns. In order to simplify the fix,
this also introduces fake_store() and dif_store() which return
corresponding wrap around addresses.

active FCoE targets
[v2] - removed the interface->enabled flag setting which prevented the
fcoe ctlr link from being brought back up after a MTU change
A rtnl_lock deadlock was observed from the rmmod thread where it
tries to unregister the fcoe_ctlr device. This unregistration
triggered a flush of the sysfs queue of the associated ctlr and led to
a call to the set_fcoe_ctlr_enabled routine. This will eventually propagate
down to call the bnx2fc_disable routine and contented for the rtnl_lock
in the same context.
This patch creates a subset of the bnx2fc_enable/disable routine which
removes the unnecesary rtnl_lock and the bnx2fc_dev_lock acquisition from
the set_fcoe_ctlr_enabled path.

In the case when a SCSI_CMD times out, bnx2fc will initiate the sending of the
ABTS. However, if the SCSI layer's SCSI command timer also times out, it'll
instantiate a task abort of the same xid.
The race condition this patch tries to fix is as follows:
SCSI_CMD timeout (20s)
thread 1 thread 2
send ABTS
rx ABTS cmpl
task abort_eh
explicit LOGO since ABTS was engaged
CLEANUP cmpl
SCSI_CMD cmpl (ABTS cmpl)
instantiate RRQ
wait 10s
attempt to send RRQ (because of LOGO, it wouldn't continue)
Note that there is no call to scsi_done for this SCSI_CMD cmpletion
in this path.
The patch changes the path of execution to call scsi_done immediately
instead of instantiating the RRQ.

Earlier logic for driver created iscsi_session->discovery_parent_idx
was to store ram index of a sendtarget entry, but driver frees
sendtarget ram index as soon as firmware is done with discovery,
which is available for further use. So changing the logic to point
iscsi_session->discovery_parent_idx to store sendtarget flashnode index.

Fixed two issues in this patch-
1) In function megasas_get_pd_list(), data read(pd_addr->deviceId) from DMAed memory is converted to CPU's endianess.
2) While register AEN, removed some endianness conversion on some fields, since their endianess is already converted.
