scsi: scsi_transport_fc: nvme: display FC-NVMe port roles

2019-04-13T00:09:34Z

Currently the FC-NVMe driver is leverating the SCSI FC transport class to access the remote ports. Which means that all FC-NVMe remote ports will be visible to the fc transport layer, but due to missing definitions the port roles will always be 'unknown'. This patch adds the missing definitions to the fc transport class to that the port roles are correctly displayed. Signed-off-by: Hannes Reinecke Reviewed-by: James Smart Reviewed-by: Ewan D.

Since the wwn_to_u64() function does not change its input, make its argument const. Cc: James Smart Cc: Hannes Reinecke Cc: Johannes Thumshirn Cc: Steffen Maier Signed-off-by: Bart Van Assche Reviewed-by: Johannes Thumshirn Signed-off-by: Martin K. Petersen

scsi: scsi_transport_fc: Add FPIN fc event codes

2019-04-09T01:29:16Z

Add a new event type - an FPIN event. Add a new routine, fc_host_fpin_rcv(), that lldd's call when an FPIN is received. The routine processes the fpin payload. For now, the routine only logs an FPIN event. Signed-off-by: Muneendra Signed-off-by: James Smart Reviewed-by: Ewan D. Milne Signed-off-by: Martin K. Petersen

scsi: scsi_transport_fc: refactor event posting routines

2019-04-09T01:29:16Z

There are two routines generating transport events that do the same thing with only a couple of values set differently. Refactor so there's a single routine doing the netlink operations to send the event. All the differences are passed as arguments. Export the symbol so the generic routine can be called by llds. Modify the existing two event routines to use the helper. Signed-off-by: James Smart Reviewed-by: Ewan D. Milne Signed-off-by: Martin K. Petersen

scsi: fc: start decoupling fc_block_scsi_eh from scsi_cmnd

2017-08-07T18:04:02Z

Scsi_cmnd is an unsuitable argument for eh_device_reset_handler(), eh_target_reset_handler(), and eh_host_reset_handler() which do not have the scope of one single SCSI command. These callbacks tend to use fc_block_scsi_eh() requiring scsi_cmnd. In order to start decoupling above eh callbacks from scsi_cmnd, introduce a new variant of the function called fc_block_rport() taking an fc_rport as argument. Refactor the old fc_block_scsi_eh() to simply delegate to fc_block_rport(). Signed-off-by: Steffen Maier Reviewed-by: Hannes Reinecke Signed-off-by: Martin K. Petersen

scsi: scsi_transport_fc: Add dummy initiator role to rport

2017-04-19T23:13:52Z

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.
