libfc: Correct check for initiator role

2013-05-10T17:19:22Z

The service_params field is being checked against the symbol FC_RPORT_ROLE_FCP_INITIATOR where it really should be checked against FCP_SPPF_INIT_FCN. Signed-off-by: Mark Rustad Tested-by: Jack Morgan Signed-off-by: Robert Love

libfc: XenServer fails to mount root filesystem.

2013-02-15T17:33:27Z

schedule_delayed_work() is using msec instead of jiffies. On PLOGI reject from target, remote port retry is scheduled @ 20 sec instead of 2sec(FC_DEF_E_D_TOV). XenServer dom0 kernel is configured with CONFIG_HZ=100Hz Signed-off-by: Krishna Mohan Signed-off-by: Robert Love

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

The rcu callback fc_rport_free_rcu() just calls a kfree(), so we use kfree_rcu() instead of the call_rcu(fc_rport_free_rcu). Signed-off-by: Lai Jiangshan Signed-off-by: Paul E. McKenney Cc: Robert Love Cc: "James E.J. Bottomley" Reviewed-by: Josh Triplett

[SCSI] libfc: Enhancement to RPORT state machine applicable only for VN2VN mode

2011-06-29T21:28:33Z

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.

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

2011-03-01T00:28:45Z

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.
