The only reference\nto them is through any outstanding exchanges pending on the rogue ports.\nIf the module is removed while a retry is set on a rogue port\n(say a Plogi retry for instance), this retry is not cancelled because there\nis no reference to the rogue port in the discovery rports list. Thus the\nlocal port can clean itself up, delete the exchange pool, and then the\nrogue port timeout can fire and try to start up another exchange.\n\nThis patch tracks the rogue ports in a new list disc-\u003erogue_rports. Creating\na new list instead of using the disc-\u003erports list keeps remote port code\nchange to a minimum.\n\n1) Whenever a rogue port is created, it is immediately added to the\ndisc-\u003erogue_rports list.\n\n2) When the rogues port goes to ready, it is removed from the rogue list\nand the real remote port is added to the disc-\u003erports list\n\n3) The removal of the rogue from the disc-\u003erogue_rports list is done in\nthe context of the fc_rport_work() workQ thread in discovery callback.\n\n4) Real rports are removed from the disc-\u003erports list like before. Lookup\nis done only in the real rports list. This avoids making large changes\nto the remote port code.\n\n5) In fc_disc_stop_rports, the rogues list is traversed in addition to the\nreal list to stop the rogue ports and issue logoffs on them. This way, rogue\nports get cleaned up when the local port goes away.\n\n6) rogue remote ports are not removed from the list right away, but\nremoved late in fc_rport_work() context, multiple threads can find the same\nremote port in the list and call rport_logoff(). Rport_logoff() only\ncontinues with the logoff if port is not in NONE state, thus preventing\nmultiple logoffs and multiple list deletions.\n\n7) Since the rport is removed from the disc list at a later stage\n(in the disc callback), incoming frames can find the rport even if\nrport_logoff() has been called on the rport. When rport_logoff() is called,\nthe rport state is set to NONE, and we are trying to cancel all exchanges\nand retries on that port. While in this state, if an incoming\nPlogi/Prli/Logo or other frames match the rport, we should not reply\nbecause the rport is in the NONE state. Just drop the frame, since the\nrport will be deleted soon in the disc callback (fc_rport_work)\n\n8) In fc_disc_single(), remove rport lookup and call to fc_disc_del_target.\nfc_disc_single() is called from recv_rscn_req() where rport lookup\nand rport_logoff is already done.\n\nSigned-off-by: Abhijeet Joglekar \u003cabjoglek@cisco.com\u003e\nSigned-off-by: Robert Love \u003crobert.w.love@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\n" }, { "commit": "6b5d6c443a9b4fd71b633cef66b5db4de8a85787", "tree": "6b0ca6eaba58d51d3a0715ba9be40bf5449b40ed", "parents": [ "9a6510eb3f030cedba32664498a610dc6d084d46" ], "author": { "name": "Mike Christie", "email": "michaelc@cs.wisc.edu", "time": "Tue Apr 21 15:32:32 2009 -0500" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@HansenPartnership.com", "time": "Mon Apr 27 10:09:54 2009 -0500" }, "message": "[SCSI] cxgb3i, iser, iscsi_tcp: set target can queue\n\nSet target can queue limit to the number of preallocated\nsession tasks we have.\n\nThis along with the cxgb3i can_queue patch will fix a throughput\nproblem where it could only queue one LU worth of data at a time.\n\nSigned-off-by: Mike Christie \u003cmichaelc@cs.wisc.edu\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\n" }, { "commit": "c751085943362143f84346d274e0011419c84202", "tree": "5323da4e3eba8126bf44e5107960ee2323d28a16", "parents": [ "7b11428d37fe65643172feff66cd0a4d72d1932a" ], "author": { "name": "Rafael J.
