* [SCSI] qla2xxx: Correct PRLI failure response code handling.Andrew Vasquez2010-10-251-6/+0
| | | | | | | | | | | This patch fixes an issue which causes the firmware to fail with a 'PRLI failed' status code (iop1 = 405). This status triggers the driver to fall into an incorrect code-path which does not attempt a login retry.

The need for this handler arose when executing kexec in specific environments caused the data of the 2nd kernel to be corrupted, due to DMA activities.

* [SCSI] qla2xxx: Group CS_RESET return status with other link level event ↵Chad Dupuis2010-10-251-4/+2
| | | | | | | | | | | | | | | | statuses. Currently when we receive a CS_RESET as a response for a SCSI command the driver will return DID_TRANSPORT_DISRUPTED back to the SCSI mid-layer. There are certain circumstances where this could cause the mid-layer to exhaust all of its retries if the FC port goes away for a short time. This will result in commands being prematurly failed. Moving the CS_RESET return code to be grouped with other link level events will cause the FC transport layer to block that target's queue thus preventing the premature exhaustion of retries.

* [SCSI] sr: fix sr_drive_status handling when initialization requiredRobert Jennings2010-10-251-0/+9
| | | | | | | | | | | | | | | | | | | | | | An sr device that reports sense data with SK/ASC/ASCQ of 2/4/2 (Not ready, Logical unit not ready, Initializing command required) will be handled in sr_drive_status as (2/4/!1) and assumed to be a 'format in progress' which returns CDS_DISC_OK. The drive will not be made ready in this case. Prior to 210ba1d1724f5c4ed87a2ab1a21ca861a915f734 sr_drive_status would have returned CDS_TRAY_OPEN and this results in an START_STOP_UNIT to close the tray, which resolves the initialization requirement. This patch adds handling for SK/ASC/ASCQ of 2/4/2 where it will return CDS_TRAY_OPEN as a means of triggering a START_STOP_UNIT. This issue is seen on the IBM POWER platform when using a file-backed, virtual optical device. The device does not support media queries through the Get Event Status Notification command which could otherwise trigger a START_STOP_UNIT call to close an open tray.

* [SCSI] fcoe: Fix broken NPIV with correction to MAC validationRobert Love2010-10-251-10/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A previous patch attempted to validate the destination MAC address of a FCoE frame by checking that MAC address against the received port's MAC address. The implementation seems fine on the surface, but any VN_Ports added using the NPIV feature will have their own MAC addresses and these MACs were not being checked, which prevented any NPIV VN_Ports from receiving frames. In other words, the following patch has broken NPIV. 519e5135e2537c9dbc1cbcc0891b0a936ff5dcd2 [SCSI] fcoe: adds src and dest mac address checking for fcoe frames Part of the offending patch is correct, but the part that broke NPIV was attempting to satisfy FC-BB-5 section D.5, 2.1- (discard frames that) "contain a destination MAC address/destination N_Port_ID pair that was not assigned by an FCF to one of the VN_Ports on the ENode" The language does _not_ say to compare the destination FC-MAP/destination N_Port_ID, but instead to compare the destination MAC address/destination N_Port_ID. >From the FC-BB-5 specification, "A properly formed FPMA is one in which the 24 most significant bits equal the Fabric’s FC-MAP value and the least significant 24 bits equal the N_Port_ID assigned to the VN_Port by the FCF." This means that we need to compare the FC Frame's destination FCID against the embedded FCID in the destination MAC address. This patch checks the lower 24 bits of the destination MAC address against destination FCID in the Fibre Channel frame. For MAC validation the first line of defense is the hardware MAC filtering. Each VN_Port will have a unicast MAC addresses added to the hardware's filtering table. The Ethernet driver should drop any MACs not destined for a programmed MAC. This patch adds a second line of defense that very specfically compares an element in the FC frame against an element in the Ethernet header, which is appropriate for the FCoE layer. Many alternative approaches were considered, including a LLD callback from libfc. The second most reasonable approach seemed to be walking the list of NPIV ports and check each of their MAC addresses against the destination MAC address of the received frame. The problem with this approach was that it is likely that performance would suffer with the more NPIV ports added to the system since every received frame would need to walk this list, comparing each entry's MAC.

No need to set fsp->cmd to NULL as this is also protected by fc_fcp_lock_pkt(), for above race the fc_fcp_lock_pkt() in fc_fcp_cleanup_each_cmd() will fail as that cmd is already done. Mike mentioned same issue at http://www.open-fcoe.org/pipermail/devel/2010-September/010533.html Similarly moved sc_cmd->SCp.ptr = NULL under scsi_queue_lock so that scsi abort error handler won't abort on completed cmds.

* [SCSI] libfc: fix setting of rport dev lossMike Christie2010-10-251-2/+2
| | | | | | | | | | | | | | | | | There does not seem to be a reason why libfc adds a 5 second delay to the user requested value for the dev loss tmo. There also does not seem to be a reason to allow setting it to 0 (or really close). This patch removes the extra 5 sec delay, and for 0 it sets it to 1 like other fc drivers. We should actually be able to set it to 0 since the queue_delayed_work API will just call queue_work, but other drivers set it to 1 in that case.

Then when we do the copy_from_user(), it would result in a memory corruption.

When the FC transport class later calls scsi_target_unblock, this has no effect, since scsi_internal_device_unblock ignores SCSI devics in this state.

| | | | | | | | | | | | | If an exchange config is executed while the local link is down, the request succeeds but the returned data is incomplete. Proceeding with the adapter activation is leading to an unpredictable behaviour (e.g. kernel panic) caused by invalid values. In such a scenario the recommended ERP is to retry the action and wait for a link up event. If the issue persists the activation has to fail.
