Linus Torvalds 670ffccb2f SCSI misc on 20171114
This is mostly updates of the usual suspects: lpfc, qla2xxx, hisi_sas,
 megaraid_sas, pm80xx, mpt3sas, be2iscsi, hpsa. and a host of minor
 updates.
 
 There's no major behaviour change or additions to the core in all of
 this, so the potential for regressions should be small (biggest
 potential being in the scsi error handler changes).

Arnd Bergmann 820f188659 scsi: aacraid: use timespec64 instead of timeval
aacraid passes the current time to the firmware in one of two ways,
either as year/month/day/... or as 32-bit unsigned seconds.

The first one is broken on 32-bit architectures as it cannot go past
year 2038. Using timespec64 here makes it behave properly on both 32-bit
and 64-bit architectures, and avoids relying on signed integer overflow
to pass times into the second interface.

The interface used in aac_send_hosttime() however is still problematic
in year 2106 when 32-bit seconds overflow. Hopefully we don't have to
worry about aacraid by that time.

Guilherme G. Piccoli d1b490939d scsi: aacraid: Add a small delay after IOP reset
Commit 0e9973ed33 ("scsi: aacraid: Add periodic checks to see IOP reset
status") changed the way driver checks if a reset succeeded. Now, after an
IOP reset, aacraid immediately start polling a register to verify the reset
is complete.

This behavior cause regressions on the reset path in PowerPC (at least).
Since the delay after the IOP reset was removed by the aforementioned patch,
the fact driver just starts to read a register instantly after the reset
was issued (by writing in another register) "corrupts" the reset procedure,
which ends up failing all the time.

The issue highly impacted kdump on PowerPC, since on kdump path we
proactively issue a reset in adapter (through the reset_devices kernel
parameter).

This patch (re-)adds a delay right after IOP reset is issued. Empirically
we measured that 3 seconds is enough, but for safety reasons we delay
for 5s (and since it was 30s before, 5s is still a small amount).

For reference, without this patch we observe the following messages
on kdump kernel boot process:

  [ 76.294] aacraid 0003:01:00.0: IOP reset failed
  [ 76.294] aacraid 0003:01:00.0: ARC Reset attempt failed

Brian King 1ae948fa4f scsi: aacraid: Fix command send race condition
This fixes a potential race condition observed on Power systems.

Several places throughout the aacraid driver call aac_fib_send or
similar to send a command to the aacraid adapter, then check the return
code to determine if the command was actually sent to the adapter, then
update the phase field in the scsi command scratch pad area to track
that the firmware now owns this command.  However, there is nothing that
ensures that by the time the aac_fib_send function returns and we go to
write to the scsi command, that the command hasn't already completed and
the scsi command has been freed.  This was causing random crashes in the
TCP stack which was tracked down to be caused by memory that had been a
struct request + scsi_cmnd being now used for an skbuff. Memory
poisoning was enabled in the kernel to debug this which showed that the
last owner of the memory that had been freed was aacraid and that it was
a struct request.  The memory that was corrupted was the exact data
pattern of AAC_OWNER_FIRMWARE and it was at the same offset that aacraid
writes, which is scsicmd->SCp.phase. The patch below resolves this
issue.

Guilherme G. Piccoli 911e572e98 scsi: aacraid: fix PCI error recovery path
During a PCI error recovery, if aac_check_health() is not aware that a
PCI error happened and we have an offline PCI channel, it might trigger
some errors (like NULL pointer dereference) and inhibit the error
recovery process to complete.

This patch makes the health check procedure aware of PCI channel issues,
and in case of error recovery process, the function
aac_adapter_check_health() returns -1 and let the recovery process to
complete successfully. This patch was tested on upstream kernel
v4.11-rc5 in PowerPC ppc64le architecture with adapter 9005:028d
(VID:DID) - the error recovery procedure was able to recover fine.

Raghava Aditya Renukunta 16ae9dd35d scsi: aacraid: Fix for excessive prints on EEH
This issue showed up on a kdump debug(single CPU on powerkvm), when EEH
errors rendered the adapter unusable. The driver correctly detected the
issue and attempted to restart the controller, in doing so the driver
attempted to read the status registers of the controller. This triggered
additional eeh errors which continued for a good 6 minutes.

Fixed by returning without waiting when EEH error is reported.

Raghava Aditya Renukunta f3ef4a74dc scsi: aacraid: Use correct channel number for raw srb
The channel being used for raw srb commands is retrieved from the utility
sent fibs and is converted into physical channel id. The driver does not
need to to do this since the management utility sends the correct channel
id in the first place and in addition the driver sets inaccurate
information in the cmd sent to the firmware and gets an invalid response.

Fixed by using channel id from srb command.

Moved the READ and WRITE switch cases to the top. Added a  default
case to the switch case and replaced duplicate scsi result value with a
macro.

The idea is that since most of scsi commands we care about performance
wise are read or write, we need to process them first.

Internally the compiler (GCC) converts a switch case into either a jump
table or a bunch of if else conditions, so placing the often used read,
write cases at the top is an effort in optimization.
