This patch reduces the number of sequential pointer derefs in
drivers/scsi/scsi_error.c
This has been submitted a number of times over a couple of years. I
believe this version adresses all comments it has gathered over time.
Please apply or reject with a reason.
The benefits are:
- makes the code easier to read. Lots of sequential derefs of the same
pointers is not easy on the eye.
- theoretically at least, just dereferencing the pointers once can
allow the compiler to generally slightly faster code, so in theory
this could also be a micro speed optimization.
- reduces size of object file (tiny effect: on x86-64, in at least one
configuration, the text size decreased from 9439 bytes to 9400)
- removes some pointless (mostly trailing) whitespace.

A useful test case for error recovery is multiple,
consecutive medium errors. When scsi_debug is started
with "opts=2" a MEDIUM ERROR is generated when block
0x1234 (4660) is read. The patch extends that to
10 consecutive blocks from 0x1234 (i.e. blocks 4660 to
4669 inclusive).
[0:0:0:0] disk ATA INTEL SSD 2CV1 /dev/sda /dev/sg0 80.0GB
[10:0:0:0] disk Linux scsi_debug 0004 /dev/sdb /dev/sg1 1.09TB
Output file not specified so no copy, just reading input
>> unrecovered read error at blk=4660, substitute zeros
...
>> unrecovered read error at blk=4669, substitute zeros
4670+10 records in
0+0 records out
10 unrecovered read errors
lowest unrecovered read lba=4660, highest unrecovered lba=4669
time to read data: 0.047943 secs at 49.87 MB/sec
BTW Change /dev/sg1 (bsg device works just as well) to
/dev/sdb to see why, with faulty media, you do not want
to use the block layer interface. Reason: time block
layer takes to do useless retries and collateral damage
to data in its 4 KB blocks (O_DIRECT mitigates the
latter).
ChangeLog:
- extend opts=2 medium error generation at block
0x1234 to 10 consecutive blocks (i.e. blocks
0x1234 to 0x123d).

I think this stems from a misunderstanding of how the ata error handler
works. ata_scsi_cmd_error_handler() gets called with a passed in list
of commands to handle. However, that list may still not be empty when
it exits. The command ata_scsi_port_error_handler() must be called
(which takes no list) before the list will be completely emptied. This
bites the sas error handler because the two are called from different
functions and the original list has gone out of scope before
ata_scsi_port_error_handler() is called. leading to some commands
dangling on bare stack, which is a potential memory corruption issue.
Fix this by manually deleting all outstanding commands from the on-stack
list before it goes out of scope.

This attribute, requested by Redhat, allows kexec-tools to know
whether the controller can honor the reset_devices kernel parameter
and actually reset the controller. For kdump to work properly it
is necessary that the reset_devices parameter be honored. This
attribute enables kexec-tools to warn the user if they attempt to
designate a non-resettable controller as the dump device.

Update scsi_debug to support the Logical Block Provisioning commands and
bits as defined in SBC3r26. The old tp* parameters have been
transitioned to the new lbp* scheme found in the draft standard.
The old tpu option to enable UNMAP is now called lbpu. tpws to signal
support for WRITE SAME(16) with the UNMAP bit set is now lbpws. Support
for WRITE SAME(10) with the UNMAP bit set is also available using the
lpuws10 parameter.
Limiting the maximum number of blocks per WRITE SAME command has been
implemented and is available via the write_same_length module parameter.
As part of the renaming process the parameter lists have been sorted
alphabetically (request from Doug).

SBC3r26 contains many changes to the Logical Block Provisioning
interfaces (formerly known as Thin Provisioning ditto). This patch
implements support for both the old and new schemes using the same
heuristic as before (whether the LBP VPD page is present).
The new code also allows the provisioning mode (i.e. choice of command)
to be overridden on a per-device basis via sysfs. Two additional modes
are supported in this version:
- WRITE SAME(10) with the UNMAP bit set
- WRITE SAME(10) without the UNMAP bit set. This allows us to support
devices that predate the TP/LBP enhancements in SBC3 and which work
by way zero-detection
Switching between modes has been consolidated in a helper function that
also updates the block layer topology according to the limitations of
the chosen command.
I experimented with trying WRITE SAME(16) if UNMAP fails, WRITE SAME(10)
if WRITE SAME(16) fails, etc. but found several devices that got
cranky. So for now we'll disable discard if one of the commands
fail. The user still has the option of selecting a different mode in
sysfs.

The conversion is quite complex given that the libata new error
handler has to be hooked into the current libsas timeout and error
handling. The way this is done is to process all the failed commands
via libsas first, but if they have no underlying sas task (and they're
on a sata device) assume they are destined for the libata error
handler and send them accordingly.
Finally, activate the port recovery of the libata error handler for
each port known to the host. This is somewhat suboptimal, since that
port may not need recovering, but given the current architecture of
the libata error handler, it's the only way; and the spurious
activation is harmless.

This driver is for Broadcom Netxtreme II 57712 chip. The following
patch contains the driver sources for bnx2fc driver. libfc/libfcoe
changes to enable bnx2fc have already gone through the fcoe
tree. bnx2fc is a SCSI low level driver that interfaces with SCSI
midlayer, libfc, libfcoe, cnic modules. bnx2fc driver uses services
of libfc for slow path operations such as FIP and fabric
discovery. The fast path IO perations are performed after offloading
the session information to the underlying FCoE firmware.

Reset using "fcoeadm -r" also needs to restart FIP before
doing libfc lport reset, this is needed for new switch firmware
requiring FIP solicitation before doing FLOGI again during reset.
So this patch does this by doing fcoe_ctlr_link_down and then
fcoe_ctlr_link_up to reset the interface.
The fcoe_ctlr_link_down call path also does lport reset
and then fcoe_ctlr_link_up re-starts the fabric login after
doing FIP solicitation first to get reset feature working
again.

Negate has higher precedence than bitwise AND. FCPHF_CRC_UNCHECKED is
0x1 so the original code is equivalent to: if (!fr_flags(fp)) { ...

When L2 driver is unloaded, libfcoe_destroy tries to access the fcoe
transport structure matching the netdev. However, since the netdev is
unregistered by that time, it fails to do so. Hence the stale mappings
exists in the fcoe-netdev list. Handle NETDEV_UREGISTER device
notification mechanism to remove the stale fcoe-netdev mapping.

EM anchors list initialization for only master port was not enough to
keep npiv working as described here:-
https://lists.open-fcoe.org/pipermail/devel/2011-January/011063.html
So this patch moves fc_exch_mgr_list_clone to update npiv ports
EMs once EM anchors list initialized.
Also some cleanup, no need to set lport = NULL as that always
get initialized later.

itself is timed out"
When abort for an exchange timed out it didn't release the reference to
the exchange resulting in a memory leak.
After discussion with the author of the patch (CC) that introduced this
bug it was suggested to revert that patch.
This reverts commit ea3e2e72eeb3e8a9440a5da965914f9b12088626.

When an fcoe interface is being destroyed; in the process the
fcoe driver will try to release all the resources it had allocated
for that interface including rports. But, it seems that it does not
release the reference held for the name server rport in that process
resulting into a memory leak. This patch fixes that memory leak.
