scsi: Add export.h for EXPORT_SYMBOL/THIS_MODULE as required

2011-10-31T23:31:23Z

For the basic SCSI infrastructure files that are exporting symbols but not modules themselves, add in the basic export.h header file to allow the exports. Signed-off-by: Paul Gortmaker

[SCSI] fcoe, libfc: initialize EM anchors list and then update npiv EMs

2011-03-01T00:31:53Z

EM anchors list initialization for only master port was not enough to keep npiv working as described here:- https://lists.open-fcoe.org/pipermail/devel/2011-January/011063.html So this patch moves fc_exch_mgr_list_clone to update npiv ports EMs once EM anchors list initialized. Also some cleanup, no need to set lport = NULL as that always get initialized later. Signed-off-by: Vasu Dev Signed-off-by: Robert Love Signed-off-by: James Bottomley

[SCSI] libfc: introduce LLD event callback

2011-02-12T17:09:04Z

This patch enables LLD to listen to rport events and perform LLD specific operations based on the rport event. This patch also stores sp_features and spp_type in rdata for further reference by LLD. Signed-off-by: Bhanu Prakash Gollapudi Signed-off-by: Robert Love Signed-off-by: James Bottomley

[SCSI] libfc: Move the port_id into lport

2010-05-17T02:22:34Z

This patch creates a port_id member in struct fc_lport. This allows libfc to just deal with fc_lport instances instead of calling into the fc_host to get the port_id. This change helps in only using symbols necessary for operation from the libfc structures. libfc still needs to change the fc_host_port_id() if the port_id changes so the presentation layer (scsi_transport_fc) can provide the user with the correct value, but libfc shouldn't rely on the presentation layer for operational values.

[SCSI] libfc: recognize incoming FLOGI for point-to-point mode

2010-04-11T14:23:37Z

When receiving a FLOGI request from a point-to-point peer, the D_ID of 0xfffffe was not recognized as belonging to one of the lports, so it was dropped. Change fc_vport_id_lookup() to treat d_id 0xfffffe as a match. Signed-off-by: Joe Eykholt Signed-off-by: Robert Love Signed-off-by: James Bottomley

[SCSI] libfc: vport link handling and fc_vport state managment

2009-12-04T18:00:57Z

NPIV vports are managed in libfc by changing their virtual link state when the parent N_Ports internal state changes. The vport link is only online when the N_Port is in a ready state (logged into the fabric). vport_state is updated as needed in this patch as well, currently the states LINKDOWN, INITIALIZING, ACTIVE, DSIABLED, and NO_FABRIC_SUPP are used. This also changes the fc_host port_state handling to differentiate between LINKDOWN and OFFLINE. Signed-off-by: Chris Leech Signed-off-by: Robert Love Signed-off-by: James Bottomley

[SCSI] libfc: add some generic NPIV support routines to libfc

2009-12-04T18:00:56Z

Adds a function to create a new VN_Port instances, which share the EM list with the N_Port, VN_Port lookup by fabric ID when responding to a new request (otherwise the exchange lookup from the N_Ports EM list is trusted to return an exchange with a cached lport value for the correct VN_Port), a pointer to a fc_vport structure for VN_Ports, and flags to indicate if an N_Port supports NPIV and if the switch/fabric allows it.
