Adapter Shutdown and Unregistration cleanup
- Correct the logic around hba shutdown. Prior to final reset, the
driver must wait for all XRIs to return from the adapter. Added logic
to poll, progressively slowing the poll rate as delay gets longer.
- Correct behavior around the rsvd1 field in UNREG_RPI_ALL mailbox
completion and final rpi cleanup.
- Updated logic to move pending VPI registrations to their completion
in cases where a CVL may be received while registration in progress.
- Added unreg all rpi mailbox command before unreg vpi.

Added driver logic to detect the last devloss timeout of remote nodes which
was still in use of FCF. At that point, the driver should set the last
in-use remote node devloss timeout flag if it was not already set and should
perform proper action on the in-use FCF and recover of FCF from firmware,
depending on the state the driver's FIP engine is in.
Find eligible FCF through FCF table rescan or the next new FCF event when
FCF table rescan turned out empty eligible FCF, and the successful flogi
into an FCF shall clear the HBA_DEVLOSS_TMO flag, indicating the successful
recovery from devloss timeout.

- In lpfc_cmpl_els_fdisc, fix code path that does not free IOCB.
- Treated firmware matching FCF property with different index as error
- Propagate error returns from lpfc_issue_els_flogi()
- Refactored lpfc_unregister_unused_fcf() to create a post
lpfc_dev_loss_tmo handler call for SLI-4 devices. Allows checking of
fcf after last ndlp released so that fcf can be released if no longer
in use.

Currently when we receive a CS_RESET as a response for a SCSI command the
driver will return DID_TRANSPORT_DISRUPTED back to the SCSI mid-layer. There
are certain circumstances where this could cause the mid-layer to exhaust all of
its retries if the FC port goes away for a short time. This will result in
commands being prematurly failed. Moving the CS_RESET return code to be
grouped with other link level events will cause the FC transport layer to block
that target's queue thus preventing the premature exhaustion of retries.

An sr device that reports sense data with SK/ASC/ASCQ of 2/4/2 (Not ready,
Logical unit not ready, Initializing command required) will be handled
in sr_drive_status as (2/4/!1) and assumed to be a 'format in progress'
which returns CDS_DISC_OK. The drive will not be made ready in this case.
Prior to 210ba1d172 sr_drive_status would
have returned CDS_TRAY_OPEN and this results in an START_STOP_UNIT to
close the tray, which resolves the initialization requirement.
This patch adds handling for SK/ASC/ASCQ of 2/4/2 where it will return
CDS_TRAY_OPEN as a means of triggering a START_STOP_UNIT.
This issue is seen on the IBM POWER platform when using a file-backed,

A previous patch attempted to validate the destination
MAC address of a FCoE frame by checking that MAC
address against the received port's MAC address. The
implementation seems fine on the surface, but any
VN_Ports added using the NPIV feature will have their
own MAC addresses and these MACs were not being checked,
which prevented any NPIV VN_Ports from receiving frames.
In other words, the following patch has broken NPIV.
519e5135e2
[SCSI] fcoe: adds src and dest mac address
checking for fcoe frames
Part of the offending patch is correct, but the part
that broke NPIV was attempting to satisfy FC-BB-5
section D.5, 2.1-
(discard frames that) "contain a destination MAC
address/destination N_Port_ID pair that was not
assigned by an FCF to one of the VN_Ports on the ENode"
The language does _not_ say to compare the destination
FC-MAP/destination N_Port_ID, but instead to compare
the destination MAC address/destination N_Port_ID.
>From the FC-BB-5 specification,
"A properly formed FPMA is one in which the 24 most
significant bits equal the Fabric’s FC-MAP value and
the least significant 24 bits equal the N_Port_ID
assigned to the VN_Port by the FCF."
This means that we need to compare the FC Frame's
destination FCID against the embedded FCID in the
destination MAC address. This patch checks the lower
24 bits of the destination MAC address against
destination FCID in the Fibre Channel frame.
For MAC validation the first line of defense is the
hardware MAC filtering. Each VN_Port will have a
unicast MAC addresses added to the hardware's
filtering table. The Ethernet driver should drop any
MACs not destined for a programmed MAC. This patch
adds a second line of defense that very specfically
compares an element in the FC frame against an element
in the Ethernet header, which is appropriate for the
FCoE layer.
Many alternative approaches were considered, including
a LLD callback from libfc. The second most reasonable
approach seemed to be walking the list of NPIV ports
and check each of their MAC addresses against the
destination MAC address of the received frame. The
problem with this approach was that it is likely that
performance would suffer with the more NPIV ports added
to the system since every received frame would need to
walk this list, comparing each entry's MAC.

Fix: When FIP frame is received, function fcoe_ctlr_vn_recv calls function
fcoe_ctlr_vn_parse which does memset for addr (&buf.rdata) which leads to
memory corruption. Code was trying to treat "buf" as struct but it was defined
as union. Fix is to change from union to struct for "buf" in function fcoe_ctlr_vn_recv.

[SCSI] libfc: reduce hold time on SCSI host lock
Currently fsp->cmd is set to NULL w/o scsi_queue_lock before
dequeuing from scsi_pkt_queue and that could cause NULL
fsp->cmd in fc_fcp_cleanup_each_cmd for cmd completing
with fsp->cmd = NULL after fc_fcp_cleanup_each_cmd taken
reference. No need to set fsp->cmd to NULL as this is also
protected by fc_fcp_lock_pkt(), for above race the
fc_fcp_lock_pkt() in fc_fcp_cleanup_each_cmd() will fail
as that cmd is already done.
Mike mentioned same issue at
http://www.open-fcoe.org/pipermail/devel/2010-September/010533.html
Similarly moved sc_cmd->SCp.ptr = NULL under scsi_queue_lock so
that scsi abort error handler won't abort on completed cmds.

There does not seem to be a reason why libfc adds a 5

setting it to 0 (or really close).
This patch removes the extra 5 sec delay, and for 0 it
sets it to 1 like other fc drivers. We should actually
be able to set it to 0 since the queue_delayed_work API
will just call queue_work, but other drivers set it to 1 in
that case.

gdth_ioctl_alloc() takes the size variable as an int.
copy_from_user() takes the size variable as an unsigned long.
gen.data_len and gen.sense_len are unsigned longs.
On x86_64 longs are 64 bit and ints are 32 bit.
We could pass in a very large number and the allocation would truncate
the size to 32 bits and allocate a small buffer. Then when we do the
