[SCSI] libfc: Add support for FDMI

2012-02-19T14:08:58Z

This patch adds support for Fabric Device Management Interface as per FC-GS-4 spec. in libfc. Any driver making use of libfc can enable fdmi state machine for a given lport. If lport has enabled FDMI support the lport state machine will transition into FDMI after completing the DNS states and before entering the SCR state. The FDMI state transition is such that if there is an error, it won't stop the lport state machine from transitioning and the it will behave as if there was no FDMI support. The FDMI HBA attributes are registed with the Management server via Register HBA (RHBA) command and the port attributes are reigstered using the Register Port(RPA) command.

[SCSI] libfc: Declare local functions static

2012-01-16T08:45:48Z

Avoid that sparse complains about missing declarations for local functions by declaring these static or by adding an #include directive. Add the __percpu annotation where it is missing. Signed-off-by: Bart Van Assche Reviewed-by: Yi Zou Signed-off-by: Robert Love Signed-off-by: James Bottomley

[SCSI] libfc: cache align struct fc_fcp_pkt fields

2011-10-02T17:55:07Z

Re-arrange its fields to avoid padding and have better cacheline alignments. Removed not used start_time, end_time and last_pkt_time fields. This all reduced this struct size to 448 from 480 and that also reduced one cacheline on x86_64 beside eliminating 8 pads. However kept logical fields together.

[SCSI] libfc, tcm_fc: add ddp_targ() to libfc function template to supprot FCoE DDP in target mode

2011-06-29T21:28:39Z

The fcoe driver can implement ddp_targ() similarly to ddp_setup() when fcoe stack works with existing target frame, e.g., tcm, where the ddp_targ() would eventually point to the underlying hardware driver's implementation of ndo_fcoe_ddp_targ() through net_device_ops. This new API sets up DDP context for target appropriately by setting required bits for DDP context.

[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: export seq_release() for users of seq_assign()

Target modules using lport->tt.seq_assign() get a hold on the exchange but have no way of releasing it. Add that. Signed-off-by: Joe Eykholt Signed-off-by: James Bottomley

[SCSI] libfc: add hook to notify providers of local port changes

2011-02-12T17:02:20Z

When an SCST provider is registered, it needs to know what local ports are available for configuration as targets. Add a notifier chain that is invoked when any local port that is added or deleted. Maintain a global list of local ports and add an interator function that calls a given function for every existing local port. This is used when first loading a provider.

[SCSI] libfc: add local port hook for provider session lookup

2011-02-12T17:02:17Z

The target provider needs a per-instance lookup table or other way to lookup sessions quickly without going through a linear list or serializing too much. Add a simple void * array indexed by FC-4 type to the fc_lport. Signed-off-by: Joe Eykholt Committed-by: Nicholas A. Bellinger Signed-off-by: Robert Love Signed-off-by: James Bottomley
