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

2011-03-01T00:31:53+00:00

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.

[SCSI] Revert "[SCSI] libfc: fix exchange being deleted when the abort itself is timed out"

2011-03-01T00:31:13+00:00

When abort for an exchange timed out it didn't release the reference to
the exchange resulting in a memory leak.

After discussion with the author of the patch (CC) that introduced this
bug it was suggested to revert that patch.

This reverts commit ea3e2e72eeb3e8a9440a5da965914f9b12088626.

[SCSI] libfc: Fixing a memory leak when destroying an interface

2011-03-01T00:28:45+00:00

When an fcoe interface is being destroyed; in the process the
fcoe driver will try to release all the resources it had allocated
for that interface including rports. But, it seems that it does not
release the reference held for the name server rport in that process
resulting into a memory leak. This patch fixes that memory leak.

[SCSI] libfc: introduce LLD event callback

2011-02-12T17:09:04+00:00

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.

[SCSI] libfc: Extending lport's roles for target if there is a registered target.

2011-02-12T17:08:22+00:00

Problem:

From initaitor machine, when queried role of target (other end of connection),
it is "initiator", hence SCSI-ml doesn't send any LUN Inquiry commands.

Fix:

If there is a registered target for FC_TYPE_FCP, extend lport's params
(capability) to be target as well, By default lport params are
INITIATOR only. Having this fix, caused initiator to send SCSI LUN
inquiry command to target.

[SCSI] libfc: Enhanced exchange ID selection mechanism and fix related EMA selection logic.

2011-02-12T17:04:27+00:00

Problem:

In case of exchange responder case, EMA selection was defaulted to the
last EMA from EMA list (lport.ema_list).  If exchange ID is selected
from offload pool and not setup DDP, resulting into incorrect
selection of EMA, and eventually dropping the packet because unable to
find exchange.

Fix:

Enhanced the exchange ID selection (depending upon request type and
exchange responder) Made necessary enhancement in EMA selection
algorithm.

Target modules using lport->tt.seq_assign() get a hold on the
exchange but have no way of releasing it.  Add that.

[SCSI] libfc: use PRLI hook to get parameters when sending outgoing PRLI

2011-02-12T17:02:22+00:00

When sending an outgoing PRLI as an initiator, get the parameters
from registered providers so that they all get a chance to decide
on roles.

The passive provider is called last, and could override the
initiator role.
