2011-03-14[SCSI] scsi_dh_rdac: Add MD36xxf into device list[email protected]1-0/+1

2011-03-14[SCSI] scsi_debug: add consecutive medium errorsDouglas Gilbert1-4/+5
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).

2011-03-14[SCSI] libsas: fix ata list corruption issueJames Bottomley1-0/+13
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. Signed-off-by: James Bottomley <[email protected]>
2011-03-14[SCSI] hpsa: export resettable host attributeStephen M. Cameron2-0/+53
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. Signed-off-by: Stephen M.

2011-03-14[SCSI] scsi_debug: Logical Block Provisioning (SBC3r26)Martin K. Petersen1-78/+105
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). Signed-off-by: Martin K.

2011-03-14[SCSI] sd: Logical Block Provisioning updateMartin K. Petersen3-58/+203
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. Signed-off-by: Martin K.

2011-02-28[SCSI] bnx2fc: Broadcom FCoE offload driverBhanu Gollapudi13-0/+9478
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.

2011-02-28[SCSI] fcoe: fix broken fcoe interface resetVasu Dev1-1/+7
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.

2011-02-28[SCSI] lpfc: force retry in queuecommand when port is transitioningMike Christie1-1/+1
If the port takes a while to transition we could exhaust the retries when using DID_TRANSPORT_DISRUPTED.

And if this is the first time we are seeing the command, (it got queued because it slipped through during the race) then it should not have its retries incremented.
