This is a trivial addition to the SG API that can receive kernel pointers. It is only used by the out-of-tree test module. So it's immediate need is questionable. For maintenance ease it might just get in, as it's very small. John. do you need this in the Kernel, or is it only for osd_ktest.ko? Signed-off-by: NJohn A.

This patch adds the Scatter-Gather (sg) API to libosd. Scatter-gather enables a write/read of multiple none-contiguous areas of an object, in a single call. The extents may overlap and/or be in any order. The Scatter-Gather list is sent to the target in what is called a "cdb continuation segment". This is yet another possible segment in the osd-out-buffer. It is unlike all other segments in that it sits before the actual "data" segment (which until now was always first), and that it is signed by itself and not part of the data buffer. This is because the cdb-continuation-segment is considered a spill-over of the CDB data, and is therefor signed under OSD_SEC_CAPKEY and higher. TODO: A new osd_finalize_request_ex version should be supplied so the @caps received on the network also contains a size parameter and can be spilled over into the "cdb continuation segment". Thanks to John Chandy <john.chandy@uconn.edu> for the original code, and investigations. And the implementation of SG support in the osd-target.

Added driver logic to detect the last devloss timeout of remote nodes which was still in use of FCF. At that point, the driver should set the last in-use remote node devloss timeout flag if it was not already set and should perform proper action on the in-use FCF and recover of FCF from firmware, depending on the state the driver's FIP engine is in. Find eligible FCF through FCF table rescan or the next new FCF event when FCF table rescan turned out empty eligible FCF, and the successful flogi into an FCF shall clear the HBA_DEVLOSS_TMO flag, indicating the successful recovery from devloss timeout.

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.

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 210ba1d1 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.

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. 519e5135 [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.
