This is handled by not resetting rdata-\u003eevent\nton NONE if the rdata is about to be deleted.\n\nHowever, that fix led to the second problem, described by\nBhanu Gollapudi, as follows:\n\u003e Here is the sequence of events. T1 is first LOGO receive thread, T2 is\n\u003e fc_rport_work() scheduled by T1 and T3 is second LOGO receive thread and\n\u003e T4 is fc_rport_work scheduled by T3.\n\u003e\n\u003e 1. (T1)Received 1st LOGO in state Ready\n\u003e 2. (T1)Delete port \u0026 enter to RESTART state.\n\u003e 3. (T1)schdule event_work, since event is RPORT_EV_NONE.\n\u003e 4. (T1)set event \u003d RPORT_EV_LOGO\n\u003e 5. (T1)Enter RESTART state as disc_id is set.\n\u003e 6. (T2)remember to PLOGI, and set event \u003d RPORT_EV_NONE\n\u003e 6. (T3)Received 2nd LOGO\n\u003e 7. (T3)Delete Port \u0026 enter to RESTART state.\n\u003e 8. (T3)schedule event_work, since event is RPORT_EV_NONE.\n\u003e 9. (T3)Enter RESTART state as disc_id is set.\n\u003e 9. (T3)set event \u003d RPORT_EV_LOGO\n\u003e 10.(T2)work restart, enter PLOGI state and issues PLOGI\n\u003e 11.(T4)Since state is not RESTART anymore, restart is not set, and the\n\u003e event is not reset to RPORT_EV_NONE. (current event is RPORT_EV_LOGO).\n\u003e 12. Now, PLOGI succeeds and fc_rport_enter_ready() will not schedule\n\u003e event_work, and hence the rport will never be created, eventually losing\n\u003e the target after dev_loss_tmo.\n\nSo, the problem here is that we were tracking the desire for\nthe rport be restarted by state RESTART, which was otherwise\nequivalent to DELETE. A contributing factor is that we dropped\nthe lock between steps 6 and 10 in thread T2, which allows the\nstate to change, and we didn\u0027t completely re-evaluate then.\n\nThis is hopefully corrected by the following minor redesign:\n\nSimplify the rport restart logic by making the decision to\nrestart after deleting the transport rport. That decision\nis based on a new STARTED flag that indicates fc_rport_login()\nhas been called and fc_rport_logoff() has not been called\nsince then. This replaces the need for the RESTART state.\n\nOnly restart if the rdata is still in DELETED state\nand only if it still has the STARTED flag set.\n\nAlso now, since we clear the event code much later in the\nwork thread, allow for the possibility that the rport may\nhave become READY again via incoming PLOGI, and if so,\nqueue another event to handle that.\n\nIn the problem scenario, the second LOGO received will\ncause the LOGO event to occur again.\n\nReported-by: Bhanu Gollapudi \u003cbprakash@broadcom.com\u003e\nSigned-off-by: Joe Eykholt \u003cjeykholt@cisco.com\u003e\nSigned-off-by: Robert Love \u003crobert.w.love@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n" }, { "commit": "7b2787ec15b9d1c2f716da61b0eec21a3f5e6520", "tree": "39b098d4253fa266ea75bf1f7feb75458e78b77d", "parents": [ "5e4f8fe7b58f4da5043b7f219fe9193cddd9262e" ], "author": { "name": "Robert Love", "email": "robert.w.love@intel.com", "time": "Fri May 07 15:18:41 2010 -0700" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Sun May 16 22:22:34 2010 -0400" }, "message": "[SCSI] libfc: Move the port_id into lport\n\nThis patch creates a port_id member in struct fc_lport.\nThis allows libfc to just deal with fc_lport instances\ninstead of calling into the fc_host to get the port_id.\n\nThis change helps in only using symbols necessary for\noperation from the libfc structures. libfc still needs\nto change the fc_host_port_id() if the port_id changes\nso the presentation layer (scsi_transport_fc) can provide\nthe user with the correct value, but libfc shouldn\u0027t\nrely on the presentation layer for operational values.\n\nSigned-off-by: Robert Love \u003crobert.w.love@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n" }, { "commit": "1b80e0f91c41db4633c0a61f727de169a9e9b275", "tree": "eda3295e4b1f609727bbb661410dd17093f62e96", "parents": [ "721cafafb66f57b461226aa197997f3e5b296f91" ], "author": { "name": "Robert Love", "email": "robert.w.love@intel.com", "time": "Fri May 07 15:18:24 2010 -0700" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Sun May 16 22:22:29 2010 -0400" }, "message": "[SCSI] libfc: Remove unused fc_get_host_port_type\n\nRemove this unused routine.\n\nSigned-off-by: Robert Love \u003crobert.w.love@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n" }, { "commit": "0b2f74a47f2b10bd4c70324820a93c070b3960a5", "tree": "406dc45508b5b23fd0212e7891f577e42e8d159e", "parents": [ "3b719d01617288f4c11307fcb933997d7ca895c3" ], "author": { "name": "Joe Eykholt", "email": "jeykholt@cisco.com", "time": "Fri Apr 09 14:22:39 2010 -0700" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Sun Apr 11 14:02:34 2010 -0500" }, "message": "[SCSI] libfc: fix hton24 macro to take expressions as args\n\nhton24(p + 3, value) would fail to compile because\np + 3[0] is not a valid expression.\n\nWent ahead and converted hton24 and ntoh24 to inline\nfunctions, which is better because the parameters\nare evalutated only once.\n\nSigned-off-by: Joe Eykholt \u003cjeykholt@cisco.com\u003e\nSigned-off-by: Robert Love \u003crobert.w.love@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n" }, { "commit": "f018b73af6db4f330ad5da9ac53997a699c30c42", "tree": "4f4e9405d923c0021771549dbdec34569c0e27a7", "parents": [ "b3ef990c1514859bffae221b9e82e46a38f1e7bf" ], "author": { "name": "Joe Eykholt", "email": "jeykholt@cisco.com", "time": "Fri Mar 12 16:08:55 2010 -0800" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Sun Apr 11 09:23:44 2010 -0500" }, "message": "[SCSI] libfc, libfcoe, fcoe: use smp_processor_id() only when preempt disabled\n\nWhen the kernel is configured for preemption, using smp_processor_id()\nwhen preemption is enabled causes a warning backtrace and is wrong\nsince we could move off of that CPU as soon as we get the ID,\nand we would be referencing the wrong CPU, and possibly an invalid one\nif it could be hotswapped out.\n\nRemove the fc_lport_get_stats() function and explicitly use per_cpu_ptr()\nto get the statistics.

With the new state,\nthe new port isn\u0027t logged into until after any old exchanges\nare reset.\n\nSigned-off-by: Joe Eykholt \u003cjeykholt@cisco.com\u003e\nSigned-off-by: Robert Love \u003crobert.w.love@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n" }, { "commit": "e95147d8fa4e63bf6d8ff249f074d0047338fc61", "tree": "c140b07c5f37586e33089f66f8d21363dd987d8d", "parents": [ "3f127ad97a985d43b3cdf4b644e77a775b6035d4" ], "author": { "name": "Vasu Dev", "email": "vasu.dev@intel.com", "time": "Wed Oct 21 16:27:39 2009 -0700" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Fri Dec 04 12:00:31 2009 -0600" }, "message": "[SCSI] libfc: removes unused disc_work and ex_list\n\nReported-by: Alex Lyakas \u003calexl@mellanox.co.il\u003e\nSigned-off-by: Vasu Dev \u003cvasu.dev@intel.com\u003e\nSigned-off-by: Robert Love \u003crobert.w.love@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n" }, { "commit": "370c3bd05cf02afabea9cd3f2de66202d6b516dc", "tree": "832cf6b3091db117f119aa8692d050f43fe0a9cb", "parents": [ "68a1750b46ad5177f7703081b5fe85624f1aa62b" ], "author": { "name": "Joe Eykholt", "email": "jeykholt@cisco.com", "time": "Tue Aug 25 14:03:47 2009 -0700" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Thu Sep 10 12:08:02 2009 -0500" }, "message": "[SCSI] libfc: use ADISC to verify rport login state\n\nWhen rport_login is called on an rport that is already thought\nto be logged in, use ADISC.

Updates fc_exch_mgr_reset to reset all exch pools of an EM,\n this required adding fc_exch_pool_reset func to reset exches\n in pool and then have fc_exch_mgr_reset call fc_exch_pool_reset\n for each pool within each EM for a lport.\n\n5. Removes no longer needed exches array, em_lock, next_xid, and\n total_exches from struct fc_exch_mgr, these are not needed after\n use of per cpu exch pool, also removes not used max_read,\n last_read from struct fc_exch_mgr.\n\n6.

Currently an EM instance is shared across all cpus to manage\n all exches for all cpus. This required em_lock across all\n cpus for an exch alloc, free, lookup and reset each frame\n and that made em_lock expensive, so instead having per cpu\n exch pool with their own per cpu pool lock will likely reduce\n locking contention in fast path for an exch alloc, free and\n lookup.\n\n 2. Per cpu exch pool will likely improve cache hit ratio since\n all frames of an exch will be processed on the same cpu on\n which exch originated.\n\nThis patch is only prep work to help in keeping complexity of next\npatch low, so this patch only sets up per cpu exch pool and related\nhelper funcs to be used by next patch. The next patch fully makes\nuse of per cpu exch pool in all code paths ie. tx, rx and reset.\n\nDivides per EM exch id range equally across all cpus to setup per\ncpu exch pool. This division is such that lower bits of exch id\ncarries cpu number info on which exch originated, later a simple\nbitwise AND operation on exch id of incoming frame with fc_cpu_mask\nretrieves cpu number info to direct all frames to same cpu on which\nexch originated.
