Mike Christie b4efdd586b [SCSI] fix q->lock not held warning when target is busy
We cannot call blk_plug_device from scsi_target_queue_ready
because the q lock is not held. And we do not need to call
it from there because when we return 0, the scsi_request_fn
not_ready handling will plug the queue for us if needed.

James Smart a257bf905e [SCSI] lpfc 8.3.1: misc fixes/changes
8.3.1 Fixes/Changes :

- Fix incorrect byte-swapping on word 4 of IOCB (data length) which
  caused LUNs to not be discovered on big-endian (e.g. PPC)

- Remove a bad cast of MBslimaddr which loses the __iomem (sparse)

- Make lpfc_debugfs_mask_disc_trc static (sparse)

- Correct misspelled word BlockGuard in lpfc_logmsg.h comment

- Replaced repeated code segment for canceling IOCBs from a list with
  a function call, lpfc_sli_cancel_iocbs().

- Increased HBQ buffers to support 40KB SSC sequences.

- Added sysfs interface to update speed and topology parameter without
  link bounce.

- Fixed bug with sysfs fc_host WWNs not being updated after changing
  the WWNs.

- Check if the active mailbox is NULL in the beginning of the mailbox
  timeout handler - fixes panic in the mailbox timeout handler while
  running IO stress test

- Fixed system panic in lpfc_pci_remove_one() due to ndlp indirect
  reference to phba through vport

- Removed de-reference of scsi device after call to scsi_done() to fix
  panic in scsi completion path while accessing scsi device after
  scsi_done is called.

- Fixed "Nodelist not empty" message when unloading the driver after
  target reboot test

- Added LP2105 HBA model description

- Added code to print all 16 words of unrecognized ASYNC events

- Fixed memory leak in vport create + delete loop

- Added support for handling dual error bit from HBA

- Fixed a driver NULL pointer dereference in lpfc_sli_process_sol_iocb

- Fixed a discovery bug with FC switch reboot in lpfc_setup_disc_node

- Take NULL termintator into account when calculating available buffer space

FUJITA Tomonori e7ee4cc04b [SCSI] sg: return EFAULT for an invalid user address
blk_rq_unmap_user() returns EFAULT if a program passes an invalid
address to kernel (the kernel fails to copy data to user space). sg
needs to pass the returned value to user space instead of ignoring
it. Before the block layer conversion, sg returns EFAULT
properly. This restores the old behavior.

Peter Jones 96bcc722c4 [SCSI] sr: report more accurate drive status after closing the tray.
So, what's happening here is that the drive is reporting a sense of
2/4/1 ("logical unit is becoming ready") from sr_test_unit_ready(), and
then we ask for the media event notification before checking that result
at all.  The check_media_event_descriptor() call isn't getting a check
condition, but it's also reporting that the tray is closed and that
there's no media.  In actuality it doesn't yet know if there's media or
not, but there's no way to express that in the media event status field.

My current thought is that if it told us the device isn't yet ready, we
should return that immediately, since there's nothing that'll tell us
any more data than that reliably:

Arjan van de Ven d4d5291c8c driver synchronization: make scsi_wait_scan more advanced
There is currently only one way for userspace to say "wait for my storage
device to get ready for the modules I just loaded": to load the
scsi_wait_scan module. Expectations of userspace are that once this
module is loaded, all the (storage) devices for which the drivers
were loaded before the module load are present.

Now, there are some issues with the implementation, and the async
stuff got caught in the middle of this: The existing code only
waits for the scsy async probing to finish, but it did not take
into account at all that probing might not have begun yet.
(Russell ran into this problem on his computer and the fix works for him)

This patch fixes this more thoroughly than the previous "fix", which
had some bad side effects (namely, for kernel code that wanted to wait for
the scsi scan it would also do an async sync, which would deadlock if you did
it from async context already.. there's a report about that on lkml):
The patch makes the module first wait for all device driver probes, and then it
will wait for the scsi parallel scan to finish.

David Howells 2344b5b685 Fix lpfc_parse_bg_err()'s use of do_div()
Fix lpfc_parse_bg_err()'s use of do_div().  It should be passing a 64-bit
variable as the first parameter.  However, since it's only using a 32-bit
variable, it doesn't need to use do_div() at all, but can instead use the
division operator.

This deals with the following warnings:

Rafael J. Wysocki c751085943 PM/Hibernate: Wait for SCSI devices scan to complete during resume
There is a race between resume from hibernation and the asynchronous
scanning of SCSI devices and to prevent it from happening we need to
call scsi_complete_async_scans() during resume from hibernation.

In addition, if the resume from hibernation is userland-driven, it's
better to wait for all device probes in the kernel to complete before
attempting to open the resume device.

FUJITA Tomonori 015640edb1 [SCSI] sg: fix q->queue_lock on scsi_error_handler path
sg_rq_end_io() is called via rq->end_io. In some rare cases,
sg_rq_end_io calls blk_put_request/blk_rq_unmap_user (when a program
issuing a command has gone before the command completion; e.g. by
interrupting a program issuing a command before the command
completes).

We can't call blk_put_request/blk_rq_unmap_user in interrupt so the
commit c96952ed70 uses
execute_in_process_context().

The problem is that scsi_error_handler() calls rq->end_io too. We
can't call blk_put_request/blk_rq_unmap_user too in this path (we hold
q->queue_lock).

To avoid the above problem, in these rare cases, this patch always
uses schedule_work() instead of execute_in_process_context().

Making the freeing of q->queue dependent on q->pool being set looks
really weird (although it is correct at the moment. But this seems
to be fixable in a much simpler way.

With the benefit that only the error case is slowed down. In both
cases we have a problem if q->queue contains an error value but it's
not -ENOMEM. Apparently this can't happen today, but it doesn't feel
right to assume this will always be true. Maybe it's the right time
to fix this as well.

Joe Eykholt 97c8389d54 [SCSI] fcoe, libfcoe: Add support for FIP. FCoE discovery and keep-alive.
FIP is the new standard way to discover Fibre-Channel Forwarders (FCFs)
by sending solicitations and listening for advertisements from FCFs.

It also provides for keep-alives and period advertisements so that both
parties know they have connectivity.  If the FCF loses connectivity to
the storage fabric, it can send a Link Reset to inform the E_node.

This version is also compatible with pre-FIP implementations, so no
configured selection between FIP mode and non-FIP mode is required.

We wait a couple seconds after sending the initial solicitation
and then send an old-style FLOGI.  If we receive any FIP frames,
we use FIP only mode.  If the old FLOGI receives a response,
we disable FIP mode.  After every reset or link up, this
determination is repeated.

Vasu Dev a0a25da2a4 [SCSI] fcoe, libfc: fix double fcoe_softc memory alloc
The foce_softc mem was reserved by libfc_host_alloc as well as
by fcoe_host_alloc.

Removes one liner fcoe_host_alloc completely, instead directly calls
libfc_host_alloc to alloc scsi_host with libfc for just one fcoe_softc
as fcoe private data.

Moves libfc_host_alloc to libfc.h since it is a libfc API, placed
lport_priv API adjacent to libfc_host_alloc since this is related
to scsi_host priv data.

Vasu Dev fdd78027fd [SCSI] fcoe: cleans up libfcoe.h and adds fcoe.h for fcoe module
Removes no where used several inline functions prefixed with skb_*
and be16_to_cpu.

Moves fcoe module specific func prototypes to fcoe.c from libfcoe.h,
moved only need for build.

Adds fcoe module header file fcoe.h and then moves fcoe module
specific fcoe_percpu_s and fcoe_softc to fcoe.h from libfcoe.h.

Moves all defines from fcoe.c to fcoe.h since now fcoe module
has its own header file fcoe.h.
