2017-04-19scsi: scsi_transport_fc: Add dummy initiator role to rportCathy Avery1-0/+1
This patch allows scsi drivers that expose virturalized fibre channel devices but that do not expose rports to successfully rescan the scsi bus via echo "- - -" > /sys/class/scsi_host/hostX/scan. Drivers can create a pseudo rport and indicate FC_PORT_ROLE_FCP_DUMMY_INITIATOR as the rport's role in fc_rport_identifiers. This insures that a valid scsi_target_id is assigned to the newly created rport and it can meet the requirements of fc_user_scan_tgt calling scsi_scan_target.

If a failed command is retried and fails again we need to enter SCSI EH, otherwise we will never be able to recover the command. To detect this situation we must not clear scmd->eh_eflags when EH finishes but rather make it persistent throughout the lifetime of the command.

2017-04-06scsi: scsi_error: count medium access timeout only once per EH runHannes Reinecke1-0/+1
The current medium access timeout counter will be increased for each command, so if there are enough failed commands we'll hit the medium access timeout for even a single device failure and the following kernel message is displayed: sd H:C:T:L: [sdXY] Medium access timeout failure. Offlining disk! Fix this by making the timeout per EH run, ie the counter will only be increased once per device and EH run.
