2012-02-19[SCSI] libiscsi: fix cmd timeout/completion raceMike Christie1-10/+10
If the driver/lib has called scsi_done and cleaned up internally but scsi layer has not yet called blk_mark_rq_complete when the command times out we hit a problem if the timeout code calls blk_mark_rq_complete first. When the time out code calls into the driver we were returning BLK_EH_RESET_TIMER and that causes the timeout code to just call us again later. We need to be calling BLK_EH_HANDLED so the timeout code can complete the completion process because it had called blk_mark_rq_complete on the command and now owns its processing.

2012-02-19[SCSI] fix the new host byte settings (DID_TARGET_FAILURE and DID_NEXUS_FAILURE)Moger, Babu2-4/+4
This patch fixes the host byte settings DID_TARGET_FAILURE and DID_NEXUS_FAILURE. The function __scsi_error_from_host_byte, tries to reset the host byte to DID_OK. But that does not happen because of the OR operation. Here is the flow. scsi_softirq_done-> scsi_decide_disposition -> __scsi_error_from_host_byte Let's take an example with DID_NEXUS_FAILURE. In scsi_decide_disposition, result will be set as DID_NEXUS_FAILURE (=0x11). Then in __scsi_error_from_host_byte, when we do OR with DID_OK. Purpose is to reset it back to DID_OK.

2012-02-19[SCSI] libfc: Add support for FDMINeerav Parikh1-3/+224
This patch adds support for Fabric Device Management Interface as per FC-GS-4 spec. in libfc. Any driver making use of libfc can enable fdmi state machine for a given lport. If lport has enabled FDMI support the lport state machine will transition into FDMI after completing the DNS states and before entering the SCR state. The FDMI state transition is such that if there is an error, it won't stop the lport state machine from transitioning and the it will behave as if there was no FDMI support. The FDMI HBA attributes are registed with the Management server via Register HBA (RHBA) command and the port attributes are reigstered using the Register Port(RPA) command.

2012-02-19[SCSI] scsi_debug: GET LBA STATUS response length correctionDouglas Gilbert1-1/+1
The SCSI GET LBA STATUS command was introduced in SBC-3 revision 20 in September 2009. At that time the Parameter Data Length field in the response had an associated byte offset of 8. Then in SBC-3 revision 25 (October 2010) that byte offset was changed to 4. The sg_get_lba_status utility in sg3_utils version 1.33 (released earlier today) has been changed to calculate the newer response length. However the implementation of GET LBA STATUS command in the scsi_debug driver still uses the original byte offset. modify the Parameter Data Length field value in the GET LBA STATUS command response to comply with the change in SBC-3 revision 25 Signed-off-by: James Bottomley <[email protected]>

2012-02-19[SCSI] hpsa: make target and lun match what SCSI REPORT LUNs returnsStephen M. Cameron1-20/+5
Some distros have a "rescan-scsi-bus.sh" script which depends on SCSI REPORT LUNs not reporting something different than what the driver tells the kernel, even if the driver uses scan_start and scan_finished methods of the SCSI host template to override the usual SCSI midlayer discovery code. Previously, 1 was added to the LUN to make room to insert the RAID controller device at LUN 0. Now, the RAID controller is moved to bus 3, and 1 is no longer added to the LUN. However, SCSI REPORT LUNS on Smart Array doesn't report physical devices like tape drives or auto-loaders as it turns out, so those particular device types still won't match. Generally the logical drives are reported first however, so at least those should match. Signed-off-by: Stephen M. Cameron <[email protected]> Signed-off-by: James Bottomley <[email protected]>
