Since the SCSI core does not reuse the tag of the SCSI command that is
being aborted by .eh_abort() before .eh_abort() has finished it is not
necessary to check from inside that callback whether or not the SCSI command
has already completed. Instead, rely on the firmware to return an error code
when attempting to abort a command that has already completed. Additionally,
rely on the firmware to return an error code when attempting to abort an
already aborted command.
In qla2x00_abort_srb(), use blk_mq_request_started() instead of
sp->completed and sp->aborted.
This patch eliminates several race conditions triggered by the removed member
variables.

I can only guess here what the races are but I agree removing the
logic here and relying on the SCSI layer to handle it correctly makes
sense.

So could we add something like WARN_ON(irqs_disabled())?

I will make the patch description more clear when I repost this patch.

qla2x00_abort_all_cmds() is typically called after the kernel driver
discovered that the firmware stopped processing commands. If the
firmware has stopped processing commands it is safe to call this
function without disabling interrupts. Even if the caller would disable
interrupts, that would only disable interrupts on the local CPU but not
on other CPUs. Additionally, disabling interrupts is not a proper
solution because if a completion interrupt arrives after a command has
been aborted that will cause trouble if the command handle has already
been associated with another command.

Thanks for the explenation. I understood the comment as 'interrupts'
have to be disabled when calling this function.

Instead of changing endianness in-place, write the data in CPU endian format
in another buffer and copy that buffer back. This patch does not change any
functionality but silences some sparse endianness warnings.

Make sure that sparse doesn't complain about the statements that load or
store the port attribute max_frame_size member. The port attribute data
structures represent FC protocol data and hence use big endian format.
This patch only changes the meaning of two ql_dbg() statements.

Hi Bart,
I'm not an expert of FDMI feature but it seems to introduce an
inconsistency with regards to structure definition. IMO, All multi-byte
binary fields and bitmasks in RPA request should be made __be32 rather
than only one. Probably that should go into one patch series where all
fields in the structure are fixed patch-by-patch or one patch that fixes
all fields at once (the latter is harder to review though).
According to Table 402 – Port Attribute Values in FC-GS-7 and RPA
request attributes in the structure above, that includes:
Supported Speed
Current Port Speed
Maximum Frame Size
Port Type
Supported Classes of Service
Port State
Number of Discovered Ports
Port Identifier
But the patch itself looks good,
Reviewed-by: Roman Bolshakov <r.bolshakov@yadro.com>

Roman

Hi Roman,
I agree with what you wrote. I have a (huge) patch pending that fixes
all endianness issues in the qla2xxx driver. I plan to post that patch
after agreement has been achieved about this patch series.
Thanks,
