The removal of the 'waitqueue_active()' test in commit d7d05548a6
("[SCSI] iscsi_tcp: fix relogin/shutdown hang") got incorrectly resolved
by David when he back-merged the main git tree into the networking tree
in commit 278554bd65 ("Merge branch 'master' of master.kernel.org:...").
There was a content conflict due to 'sock->sk->sk_sleep' being changed
into 'sk_sleep(sock->sk)' in the networking tree, but David didn't pick
up the iscsi change from the main tree.

device offline
Problem description:
--------------------
The problem reported by one of the customer was when a logical array
is deleted(from the SDK, from the GUI, from arcconf) then the
corresponding physical device (/dev/sdb, for example) is not removed
from the Linux namespace. So you end up with a "dead" device
entry. And some of the linux tools go slightly wonky.
Solution:
---------
Based on the notification from FW, the driver calls
"scsi_remove_device" for the DELETED drive. This call not only informs
the scsi device status to the SCSI mid layer and also it will remove
corresponding scsi device entries from the Linux sysfs.

Problem description:
--------------------
The issue reported by one of the customer was able to read LBA beyond
the array reported size with "sg_read" utility. If N is the last block
address reported, then should not be able to read past N,
i.e. N+1. But in their case, reported last LBA=143134719. So should
not have been able to read with LBA=143134720, but it is read without
failure, which means reported size to the OS is not correct and is
less than the actual last block address.
Solution:
---------
Firmware layer exposes lesser container capacity than the actual
one. It exposes [Actual size - Spitfire space(10MB)] to the OS, IO's
to the 10MB should be prohibited from the Linux driver. Driver checks
LBA boundary, if its greater than the array reported size then sets
sensekey to HARDWARE_ERROR and sends the notification to the MID
layer.

There are two conditions for ATA pass thru command that falls into
'SRB_STATUS_ERROR' condition.
1. When the "CC" bit is set by the host in ATA pass-through CDB
- Even for the successful completion, SCSI target shall generate
check condition.
- Driver returns a result code of SAM_STAT_CHECK_CONDITION, with a
driver byte of DID_OK to the mid layer.
Below is the snippet of existing code which fills a result code
of SAM_STAT_CHECK_CONDITION:
***********************************
if (le32_to_cpu(srbreply->scsi_status) == SAM_STAT_CHECK_CONDITION) {
int len;
scsicmd->result |= SAM_STAT_CHECK_CONDITION;
..........
************************************
2. When the "CC" bit is reset by the host and if SCSI target generates
a check condition when an error occurs.
- Driver returns a result code of SAM_STAT_CHECK_CONDITION, with a
driver byte of DID_ERROR to the mid layer.

The default driver setting is "expose_physicals=0", which means raw
physical drives are not exposed to OS. If the user wants to expose
connected physical drives, enable "expose_physicals" module parameter.
With the new JBOD firmware, physical drives are not available for
"expose_physicals>0". In function "aac_expose_phy_device", modified
to reset the appropriate bit in the first byte of inquiry data. This
fix exposes the connected physical drives.

When the JBOD is created from the OS using Adaptec Storage Manager
utility device is not available under FDISK until a system restart is
done.
Solution:
---------
AIF handling: If there is a JBOD drive added to the system, identify
the old one with scsi_device_lookup() and remove it to enable a fresh
scsi_add_device(); else the new JBOD is not available until reboot.

Currently fcoe module ref count is used for tracking
active fcoe instances, it means each fcoe instance create
increments the count while destroy dec the count.
The dec is done only if fcoe instance is destroyed from
/sysfs but not if destroyed due to NETDEV_UNREGISTER event.
So this patch moves only module_put doing dec to common
fcoe_if_destroy function, so that dec would occur on ever
fcoe instance destroy.

Currently rtnl mutex is grabbed during fcoe create, destroy, enable
and disable operations while sysfs s_active read mutex is already
held, but simultaneously other networking events could try grabbing
write s_active mutex while rtnl is already held and that is causing
circular lock warning, its detailed log pasted at end.
In this log, the rtnl was held before write s_active during device
renaming but there are more such cases as Joe reported another
instance with tg3 open at:-
http://www.open-fcoe.org/pipermail/devel/2010-February/008263.html
This patch fixes this issue by not waiting for rtnl mutex during
fcoe ops, that means if rtnl mutex is not immediately available
then restart_syscall() to allow others waiting in line to
grab s_active along with rtnl mutex to finish their work first
under these mutex.
Currently rtnl mutex was grabbed twice during fcoe_destroy call flow,
second grab was from fcoe_if_destroy called from fcoe_destroy after
dropping rtnl mutex before calling fcoe_if_destroy, so instead made
fcoe_if_destroy always called with rtnl mutex held to have this mutex
grabbed only once in this code path.
However left matching rtnl_unlock as-is in its original place as it was
dropped there for good reason since very next call causes synchronous
fip worker flush and if rtnl mutex is still held before flush
then that would cause new circular warning between fip->recv_work and
rtnl mutex, I've added detailed comment for this on fcoe_if_destroy
calling and rtnl muxtes unlocking.

This patch creates a port_id member in struct fc_lport.
This allows libfc to just deal with fc_lport instances
instead of calling into the fc_host to get the port_id.
This change helps in only using symbols necessary for
operation from the libfc structures. libfc still needs
to change the fc_host_port_id() if the port_id changes
so the presentation layer (scsi_transport_fc) can provide
the user with the correct value, but libfc shouldn't
rely on the presentation layer for operational values.

The problem occurring is a hw-race where there's an outstanding read-flash
operation occurring while the chip is being reset (done via an sg_reset script).
After the chip is paused, the read-flash operation never completes and the
DPC thread, while trying to complete the reset, is never able to recover,
as the HW appears to be hung...
The fix is to wait for outstanding flash operation prior to doing a sg_reset -h.
And to wait for reset to complete before any flash operations.
Note, during the wait, if any of the operation (reset/flash) does not complete,
failure is returned to the upper layer. The upper layer either need to
fail or retry.

The qla2xxx driver uses a port_id_t to mark the start of its enumerations. gcc
is complaining that wrap.b24 may be used uninitialized, but this doesn't look
to be possible. Silence it.

Currently we can only issue the task management (TM)
commands via the mailbox mechanism. This is a limitation,
since only one mailbox command can be issued at a time.
The purpose of this effort is to provide support for
issuing and processing the respose to TM and Marker
IOCBs asynchronously. Towards achieving this, the
consolidated srb architecture that is currently used for
BSG and IOCB/Logio commands has been enhanced and used.

Currently, BSG and IOCB/Logio commands have a different
framework (srb structs). The purpose of this effort is to
consolidate them into a generalized framework for these
as well as other asynchronous operations in the future.

Migrate to a consistent set of debug entries during status-IOCB
handling:
* group CS_TIMEOUT handling with CS_PORT_UNAVAILABLE and the like
(more regrouping of common behaviour).
* drop CS_DATA_OVERRUN handling as it now falls into the
'default' case (still returns DID_ERROR).
* consolidate CS_RESET and CS_ABORTED handling, as we the only
functional difference was a printk() (still returns DID_RESET).
* dropped all the earlier inconsistent [qla_]printk()s sprinkled
throught the needlessly large case-statement. Failure case
I/Os are now logged with a 'standard' format:
<command failure details>
<command generic details>
so, for example a dropped-frame is logged as:
qla2xxx 0000:13:00.0: scsi(16:0:0) Dropped frame(s) detected (4000 of 4000 bytes).
qla2xxx 0000:13:00.0: scsi(16:0:0) FCP command status: 0x15-0x18 (70018) \
oxid=78 ser=76 cdb=280000 len=4000 rsp_info=0 resid=0 fw_resid=4000
which should now convey all relevant information.

The driver should not be unloaded if any application is using it.
To disallow driver unload, driver use count must be incremented.
Application uses this char device as handle and increases driver

Currently error status is cleared only after the uncorrectable fatal errors
in the qla2xxx_pci_slot_reset. This fix is added to clear the error status in
qla2xxx_pci_resume. This way for both fatal and non-fatal errors the error
status gets cleared properly.
