Ferenc Wagner 8af3d8d5bc [SCSI] fusion: ensure NUL-termination of MptCallbacksName elements
Using strlcpy instead of memcpy makes the strlen() calls superfluous
and also ensures zero-termination of the copied string.
At the same time get rid of the magic constant 50.

Actually, I can't see why copying the callback name is necessary
instead of simply storing a pointer to it (just like to the callback
function itself), but that goes beyond the scope of this fix.

kashyap.desai@lsi.com 98cbe371fd [SCSI] mptfusion: Fix for device offline while doing aggressive HBA reset
[Resend patch as per Bernd Schubert comment ]

Issue:

Device goes offline while doing aggressive HBA reset
along with IO using some utility.

Root cause:

FW goes into bad state due to aggressive reset. Softreset does not
help to recover FW. And also aggressive reset open up the window for
Error handling thread to kicked off at the same time HBA will be in
constant RESET loop as part of aggressive reset test case can lead
Device to goes offline.

Changes:

1. Added extra check as below inside eh_timed_out call back as below.
   if(ioc->ioc_reset_in_progress) Rc = EH_TIMER_RESET

2. Removed " DOORBELL_ACTIVE" check for SAS controller from task
   management context.  Since SAS controller uses high priority queue
   for task management. This check is not required for SAS controller.

3. Moved SoftReset call to HardReset from Task Mgmt context.

kashyap.desai@lsi.com e62cca19a9 [SCSI] mptfusion: Better handling of DEAD IOC PCI-E Link down error condition
Find Non-Operation IOC and remove it from OS: Detecting
dead(non-functional) ioc will be done reading doorbell register value
from fault reset thread, which has been called from work thread
context after each specific interval. If doorbell value is 0xFFFFFFFF,
it will be considered as IOC is non-operational and marked as dead
ioc.

Once Dead IOC has been detected, it will be removed at pci layer using
"pci_remove_bus_device" API.

Kashyap, Desai c9de7dc483 [SCSI] mptfusion: Block Error handling for deleting devices or Device in DMD
Issue description:
In multipath topology, when device deletion is in transient state,
multipath driver can call blk_flush_queue() as part of path failure.
Before device get deleted from OS, Device may go OFFLINE as part of error
handling kicked off triggered from multipathing driver. Above condition hits
more frequently if device missing delay timer (which is LSI specific firmware
parameter) is non zero value.

root cause of this issue is Error handling thread is getting kicked off for
device which is not really present(in transient state of deleting).

This patch has solution for this issue. driver is now using eh_timed_out
callback. See below.

mptsas_transport_template->eh_timed_out = mptsas_eh_timed_out

Using mptsas_eh_timed_out function, driver can decide weather vdevice is
under Device missing delay or deleting state.

for either of those cases, there is BLK_EH_RESET_TIMER return to scsi mid
and error handling thread will not be kicked off for that particular scsi
command.

Kashyap, Desai b68bf096d4 [SCSI] mptfusion: schedule_target_reset from all Reset context
Issue:
target reset will be queued to driver's internal queue to get schedule
later. When driver add target into internal target_reset queue we will block IOs
on those target using scsi midlayer API. Now due to some cause driver is not
executing those target_reset list and it is always in block state.

Changes:
now we are clearing target_reset queue from all other Callback context
instead of only DeviceReset context.Now wherever driver is clearing
taskmgmt_in_progress flag it is considering target_reset queue cleanup
also.

Free FIFO's. All the Message Frames on Reply Free FIFO are
discarded. All posted buffers are freed, and event notification is
turned off.  IOC doesnt reply to any outstanding request. This will
transfer IOC to READY state.  Message unit ready is less expensive
operations than Hard Reset.  soft reset will not force Firmware to
reload again, it only do clean up of Message units.

Kashyap, Desai 14d0f0b063 [SCSI] mpt fusion: Fixing 1078 data corruption issue for 36GB memory region
The reason for this change is there is a data corruption when four different
physical memory regions in the 36GB to 37GB region are
accessed. This is only affecting 1078.

The solution is we need to use different addressing when filling in
the scatter gather table for the effected memory regions.  So instead
of snooping on all four different memory holes, we treat any physical
addresses in the 36GB address with the same algorithm.

The fix is explained below
1) Ensure that the message frames are NOT located in the trouble
region. There is no remapping available for message frames, they must
be allocated outside the problem region.
2) Ensure that Sense buffers are NOT in the trouble region. There is
no remapping available.
3) Walk through the SGE entries and if any are inside the trouble region
   then they need to be remapped as discussed below.
	1) Set the Local Address bit in the SGE Flags field.
  	MPI_SGE_FLAGS_LOCAL_ADDRESS
  	2) Ensure we are using 64-bit SGEs
  	3) Set MSb (Bit 63) of the 64-bit address, this will indicate buffer
	location is Host Memory.

Michael Reed 7748369f49 [SCSI] mptsas: do not use ioc->handle to locate hba portinfo structure
While performing hardware raid reset testing via the raid's client, I
noticed that sometimes, following the reset, that there would be more
raid targets in the lsscsi output than there actually were raid
targets.  I tracked this down to the following issue.

Fusion cannot always find the mptsas_portinfo structure for the hba
because it uses the handle stored in ioc->handle to locate it.  The
problem is that the firmware can change the handle associated with the
hba when h/w raid is reset (via the raid client).  When this happens,
the driver will allocate another mptsas_portinfo structure and link it
into the chain of said structures.  This ultimately causes confusion
within the driver resulting in targets not being removed when they
should be.

Eric Moore pointed out that the hba's portinfo structure is always the
first structure on the sas_topology list.  This patch modifies
mptsas.c to access the hba's portinfo structure by taking the first
structure on said list.

Cleaning up prints that use the xxx_printk API, in that the fusion
preamble "mptbase: iocX" follows the info provided by the print API.
The way its currently coded, the [H:C:T] print in sdev_printk will be
inbetween "mptbase" and "iocX", instead of before.

Eric Moore e8206381f5 [SCSI] mpt fusion: lock down ScsiLookup
ScsiLookup is an array of pending scmd pointers that the scsi lld
maintains. This array is touched from queuecommand, eh threads, and
interrupt context. This array should put under locks, hence this patch
to synchronize its access.  I've added some nice little function
wrappers for this, and moved the ScsiLookup array over to MPT_ADAPTER
struct.

Recently LSI Logic Corp was renamed as LSI Corp, so whereever there is
a reference of LSI Logic, it is changed to LSI in mpt fusion driver
code.
