[SCSI] libfc: Add support for FDMI

2012-02-19T14:08:58+00:00

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: Make the libfc Common Transport(CT) code generic

2012-02-19T14:08:58+00:00

Currently the libfc Common Transport(CT) calls assume that
the CT requests are Name Server specific only. This patch
makes it more flexible to allow more FC-GS services to make
use of these routines.

[SCSI] libfc: introduce __fc_fill_fc_hdr that accepts fc_hdr as an argument

2011-03-01T00:32:33+00:00

fc_fill_fc_hdr() expects fc_frame as an argument. Introduce __fc_fill_fc_hdr to
accept fc_frame_header as an argument.

[SCSI] libfc: add fc_fill_reply_hdr() and fc_fill_hdr()

2010-07-28T14:06:00+00:00

Add functions to fill in an FC header given a request header.
These reduces code lines in fc_lport and fc_rport and works
without an exchange/sequence assigned.

fc_fill_reply_hdr() fills a header for a final reply frame.

fc_fill_hdr() which is similar but allows specifying the
f_ctl parameter.

Add defines for F_CTL values FC_FCTL_REQ and FC_FCTL_RESP.
These can be used for most request and response sequences.

v2 of patch adds a line to copy the frame encapsulation
info from the received frame.

[SCSI] libfc: Move the port_id into lport

2010-05-17T02:22:34+00:00

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: register FC4 features with the FC switch

2009-12-04T18:01:20+00:00

Customers and certification tests have pointed out that we don't
show up on the switch management software as an initiator.

On some MDS switches 'show fcns database' command shows libfc
initiators as 'fcp' not 'fcp:init' like other initiators.

On others switches, I think the switch gets the features by doing a PRLI,
but it may be only certain models or under certain configurations.

Fix this by registering our FC4 features with the RFF_ID CT request
after local port login and after the RFT_ID.

[SCSI] libfc: fix RNN_ID smashing skb payload

2009-12-04T18:01:15+00:00

The code that filled in the name server RNN_ID (register node name)
request had somehow gotten a line in it from the RFT_ID code
which copies 32 bytes of data over the relatively short payload.
This caused some corruption and hangs.

Simply deleted the extraneous line.
