[SCSI] qla2xxx: Honor NVRAM port-down-retry-count settings. · a7b61842

Andrew Vasquez authored May 07, 2007

Hardcoding the qlport_down_retry module-parameter
effectively disallowed any user-defined NVRAM setting to go
into effect.

[SCSI] zfcp: Stop system after memory corruption · b03670e5

Christof Schmitt authored May 07, 2007

For each request that is sent to the FCP adapter, zfcp allocates
memory. Status information and data that is being read from the
device is written to this memory by the hardware. After that,
the hardware signals this via the response queue and zfcp
continues processing.

Now, if zfcp detects that there is a signal for an incoming
response from the hardware, but there is no outstanding request
for that request id, then some memory that can be in use anywhere
in the system has just been overwritten. This should never happen,
but if it does, stop the system with a panic.

[SCSI] aacraid: superfluous adapter reset for IBM 8 series ServeRAID controllers · 9e4d4a5d

Salyzyn, Mark authored May 01, 2007

The kexec patch introduced a superfluous (and otherwise inert) reset of
some adapters. The register can have a hardware default value that has
zeros for the undefined interrupts. This patch refines the test of the
interrupt enable register to focus on only the interrupts that affect
the driver in order to detect if an incomplete shutdown of the Adapter
had occurred (kdump).

[SCSI] tmscsim: remove bogus endianness conversions · 46e5ba2b

Guennadi Liakhovetski authored May 04, 2007

cpu_to_le32 endianness conversions in tmscsim.c, followed by
arithmetic operations don't look correct. Besides, {in,out}[wl]
already perform the necessary conversions. Further, bus addresses
of request buffers are guaranteed to be (mapped) under 4G by
current scsi- and block-layer defaults. This could be explicitly
enforced by using blk_queue_bounce_limit(), which, however,
doesn't seem to be the common practice among SCSI drivers.

[SCSI] ipr: Better handle adapter boot time errors · 473b1e8e

Brian King authored May 02, 2007

If an ipr adapter encounters an adapter error requiring an
adapter reset to recover from prior to driver load time, the
error will be ignored and recovery will not happen until the
initial timeout occurs waiting for the firmware to come ready,
which means a five minute timeout. Fix is to read the interrupt
register before clearing any of the interrupts at probe time.

Now that we have the much better esp_scsi driver and low level drivers
are easy to port over deprecate the old NCR53C9x driver.

I've Cc'ed the m68k and mips lists because all but one bus glues are
for these platforms. Chances stand bad for the remaining driver,
mca_53c9x which hasn't gotten any non-trivial update since it was
merge in late 2.1.x and whos maintainers mail address bounces.

[SCSI] fc_transport: make all rports wait dev_loss_tmo before removing them · 92740b24

James Smart authored Apr 27, 2007

Per the comment in the change - it's not always prudent to immediately
remove the rport upon first notice of a disconnect. Make all rports
wait dev_loss_tmo before being deleted (and each could have a separate
dev_loss_tmo value).

The original post was:
http://marc.info/?l=linux-scsi&m=117392196006703&w=2

The repost contains the following changes:
 - Bug fix in fc_starget_delete(). Dev_loss_tmo_callbk() was called prior to
   tearing down the target. The callback is to be the last thing called, as
   it tells the LLDD that the rport is completely finished and can be torn
   down.  Rework so that terminate_rport_io() is called to terminate the
   outstanding io. Isolated work so it's is simply "starget" work.
 - Fix holes in original patch. There were code paths that did not expect
   the dev_loss_tmo timer to be running for the non-fcp rports.
 - Bug Fix: the transport wasn't protecting against a LLDD calling
   fc_remote_port_delete() back-to-back. Thus, the dev_loss_tmo timer
   could be restarted such that it fires after the rport had been deleted.
   Validate rport state before starting the timer.
