      [SCSI] libfc: post reset event on lport reset · 9b7d1613
      由 Vasu Dev 提交于 
      Post an FCH_EVT_LIPRESET event on lport reset as
as lport reset occurs on FIP cleat virtual link,
this could be due to change in fcoe vlan and this
event will allow user app fcoemon to switch to
new fcoe vlan.

      [SCSI] libfc:Fix for exchange/seq loopup failure when FCoE stack is used as target and connected to windows initaitor

Problem: Linux based SW target (TCM) connected to windows initiator
was unable to satisfy write request of size > 2K.

Fix: Existing linux implememtation of FCoE stack is expecting sequence
number to match w.r.t incoming framme. When DDP is used on target in
response to write request from initiator, SW stack is notified only
when last data frame arrives and only the pakcket header of last data
frame is posted to NetRx queue of storage. When that last packet was
processed in libfc:Exchange layer, implementation was expecting
sequence number to match, but in this case sequence number which is
embedded in FC Header is assigned by windows initaitor, hence due to
sequence number mismatch post-processing which shall result into
sending RSP is not done. Enhanced the code to utilize the sequence
number of incoming last frame and process the packet so that, it will
eventually complete the write request by sending write response (RSP)
GOOD.

Notes/Dependencies: This patch is validated using windows and linux
initiator to make sure, it doesn't break anything.

      [SCSI] libfc: Enhancement to RPORT state machine applicable only for VN2VN mode · 48058481
      由 Kiran Patil 提交于 
      Problem: Existing RPORT state machine continues witg FLOGI/PLOGI
process only after it receices beacon from other end. Once claiming
stage is over (either clain notify or clain repose), beacon is sent
and state machine enters into operational mode where it initiates the
rlogin process (FLOGI/PLOGI) to the peer but before this rlogin is
initiated, exitsing implementation checks if it received beacon from
other end, it beacon is not received yet, rlogin process is not
initiated. Other end initiates FLOGI but peer end keeps on rejecting
FLOGI, hence after 3 retries other end deletes associated rport, then
sends a beacon. Once the beacon is received, peer end now initiates
rlogin to the peer end but since associated rport is deleted FLOGI is
neither accepted nor the reject response send out because rport is
deleted. Hence unable to proceed withg FLOGI/PLOGI process and fails
to establish VN2VN connection.

Fix: VN2VN spec is not standard yet but based on exitsing collateral
on T11, it appears that, both end shall send beacon and enter into
'operational mode' without explictly waiting for beacon from other
end. Fix is to allow the RPORT login process as long as respective
RPORT is created (as part of claim notification / claim response) even
though state of RPORT is INIT. Means don't wait for beacon from peer
end, if peer end initiates FLOGI (means peer end exist and
responding).

Notes: This patch is preparing the FCoE stack for target wrt
offload. This is generic patch and harmless even if applied on storage
initiator because 'else if' condition of function 'fcoe_oem_found'
shall evaluate to TRUE only for targets.
