This is a regression introduced by commit
1ff9918b625457ce20d450d00f9ed0a12ba191b7 The else statement here is breaking
the initiator logic of allocating xid from the offloaded em xid pool for READ
I/O only to use DDP, as shown by the snippet of trace below, where the WRITE
is using xid 0x5 from the offloaded em xid pool:
Protocol VID Len S_ID D_ID OX_ID RX_ID Summary
..
*FCP 228 96 0b.08.01 -> 01.0f.00 0x0005 0xffff SCSI: Write(10) LUN: 0x00
FCP 228 76 01.0f.00 -> 0b.08.01 0x0005 0x828d XFER_RDY
...
The bug is in the else statement, for both initiator and target, the
new command will have FC frame header bit 23 (FC_FC_EX_CTX) cleared as it was
originated from the initiator. Also, this is assuming the frame header is
already filled up, which is only true for target since for initiator, this is a
new frame and oem_match gets called when em tries get xid for this i/o before
it is filled up and sent out.
The fix is to check if there is a fc_fcp_pkt associated w/ this frame from
fr_fsp(fp), since fr_fsp(fp) is NULL for tcm_fc target and non-I/O frame in
initiator. This should also return true for target only if it is an
FC_RCTL_DD_UNSOL_CMD and rx_id is not allocated.

There's a zero day mistake in the megaraid driver in that the code that
obtains the version number does a >> 8 on a char quantity. This >>8 causes a
sparse warning because it always produces zero. Al Viro suggested these
shifts should be >> 4 thus treating the firmware version as a BCD quantity.
However, in the interests of safety we've elected to replace the >> 8
quantities with an explicit zero, thus quieting the sparse warning while
preserving the same (albeit incorrect) version number as had previously been
seen.

The sdev is deleted from starved list and then try to dispatch from this
device. It's quite possible the sdev can't eventually dispatch a request,
then the sdev will be in starved list tail. This isn't fair.
There are two cases here:
1. unplug path. scsi_request_fn() calls to scsi_target_queue_ready(), then
the dev is removed from starved list, but quite possible host queue isn't
ready, the dev is moved to starved list without dispatching any request.
2. scsi_run_queue path. It deletes the dev from starved list first (both
global and local starved lists), then handles the dev. Then we could have
the same process like case 1.
This patch fixes the first case. Case 2 isn't fixed, because there is a
rare case scsi_run_queue finds host isn't busy but scsi_request_fn finds
host is busy (other CPU is faster to get host queue depth). Not deleting
the dev from starved list in scsi_run_queue will keep scsi_run_queue
looping (though this is very rare case, because host will become busy).
Fortunately fixing case 1 already gives big improvement for starvation in
my test. In a 12 disk JBOD setup, running file creation under EXT4, this
gives 12% more throughput.

When expander connected in x2 or x4 mode and with IO runnning, if
a cable from wideport is plugged out from the phy, IO's start failing
on all the targets.
Observed that when cable is pulled with IO running, cominit is
happening on all the links and IO's start dropping to 0 and eventually
the whole IO fails. Second observation, target is trying to open and
SCU is responding with "Open reject no destination".
A cause of the problem is when the port went from the "ready
configuring substate" back to "ready configuring substate" as a result
of phy being pulled off, scic suspended the port task scheduler
register. As a result no IO was allowed and in the "substate
configuring enter" routine the IO never goes back to 0. As a result
the port never comes out of "ready substate configuring".
The patch adds a mechanism of activate and deactivate phy when a port
link up, which fixes the problem.

early to kernel, which caused the first IOs (report luns, inquirys)

Failure seen pulling a cable from a x4 port configured in manual port
configuration (MPC) mode (MPC mode is set by the the OEM paramaters
provided by the platform or isci_firmware.bin). While IO running to
devices behind and expander, plugging out the cable from phy is causing
IO failures and IO drops on disks and never recover.
It happens because during link up/down the phy were being taken out of
the port.
Fix: during link down the phy is kept in the same logical port.

fc_remote_port_rolechg
This patch fixes a bug where devloss is not called on fc_host teardown.
The issue is seen if the LLDD uses rport_rolechg to add the target role
to an rport.
When an rport goes away, the LLDD will call fc_remote_port_delete, which
will start the devloss timer. If the timer expires, the transport will
call the devloss callback and set the FC_RPORT_DEVLOSS_CALLBK_DONE flag.
However, the rport structure is not deleted, it is retained to store the
SCSI id mappings for the rport in case it comes back. In the scenario
where it does come back, and the driver calls fc_remote_port_add, but does
not indicate the "target" role for the rport - the create will clear the
structure, but forgets to clear FC_RPORT_DEVLOSS_CALLBK_DONE flag (which
is cleared if it's added with the target role). The secondary call, of
fc_remote_port_rolechg to add the target role also does not clear the flag.
Thus, the next time the rport goes away, the resulting devloss timer
expiration will not call the driver callback as the flag is still set.
This patch adds the FC_RPORT_DEVLOSS_CALLBK_DONE flags to the list of
those that are cleared upon reuse of the rport structure.

This patch re-implements LUN Masking feature using SCSI Slave Callouts. With
the new design in the slave_alloc entry point; for each new LUN discovered we
check with our internal LUN Masking config whether to expose or to mask this
particular LUN. We return -ENXIO (No such device or address) from slave_alloc
for the LUNs we don't want to be exposed. We also notify the SCSI mid-layer
to do a sequential LUN scan rather than REPORT_LUNS based scan if LUN masking
is enabled on our HBA port, since a -ENXIO from any LUN in REPORT_LUNS based
scan translates to a scan abort. This patch also handles the dynamic lun
masking config change from enable to disable or vice-versa by resetting
sdev_bflags of LUN 0 appropriately.
