fc_rport_logoff drops the rport lock in order to cancel work that may be pending. This is undesirable as the state can completely change, and the caller may not expect that the lock could've been dropped. If there is work pending, it will acquire the rdata mutex and so we're protected and can change the event from READY to DELETE. Queue the work only if there is no event already pending. There were a couple other cases where the state was set to DELETE and work queued, even though the state may have already been DELETE. Fix these using a common function fc_rport_enter_delete().

State RPORT_ST_NONE was intented to be an invalid state (0), never used. This was a misguided attempt to be sure it was always initialized. Having an extra state meaning nothing requires switch statements to have a case covering that state. State NONE has been used instead to mean the remote port is being deleted. Changing the name to RPORT_ST_DELETE. Signed-off-by:

We saw periodic messages like: WARNING: at drivers/scsi/libfc/fc_exch.c:825 fc_seq_start_next+0x30/0x4b This was due to trying to allocate a sequence in a request handler when the exchange had been reset. Delete the WARN_ON. Signed-off-by:

During an fcoe module unload, we saw a problem where fc_rport_work() finds the lport has been freed. The rdata points to an area containing 0x6b6b6b6b... the pool poison value from kmem_free(). In fcoe_if_destroy() we call fc_fabric_logoff() then fc_lport_destroy(). fc_fabric_logoff() flushes the remote port work, but we're still receiving requests, and an RSCN or PLOGI arrives which creates more rports. Note that although the LLD also checks link_up, it doesn't do it under the lport mutex, so it can deliver frames to fc_lport_recv_req() even after link_up is cleared. So, re-check link_up there. We need to flush the rports by calling disc_stop_final() after we clear link_up. Signed-off-by:

When removing the fcoe module, several lports were being shut down through fc_lport_fabric_logoff(). Occasionally, one would enter reset state before fc_lport_destroy() was called, and since link_up was still true, it would log back in. If we just clear link_up earlier, then we wouldn't be accepting LOGO requests from other initiators while we are shutting down. Fix by changing the LOGO response handler to enter DISABLED instead of RESET. Add an fc_lport_enter_disabled() function which does what fc_lport_enter_reset() did, except it doesn't proceed to FLOGI state. Move the code that was common between fc_lport_enter_reset() and fc_lport_enter_disabled() into a new fc_lport_reset_locked() function. Signed-off-by:

The state NONE was meant to be invalid, but has been used as the initial state. Rename it to be DISABLED, as more descriptive. Further patches will make it the like the RESET state, except it won't transition to FLOGI until fc_lport_fabric_login() is called. Signed-off-by:

libfc debug messages currently show 'lport: <fc-id>:' wher <fc-id> is the hex assigned port-id. When the lport is logged off, that will be zero, so its hard to distinguish which instance is involved. The FC-ID can change if the port is re-patched or changes VSANs. Two lports may even have the same FC-ID if connected to isolated SANs. Change the debug messages to print the SCSI host number "hostN:", which will not change for the life of the lport. Still show the FC_ID on lport messages. Also, add a macro to FC_RPORT_ID_DBG for rport debugging where there's no rdata structure involved. It takes the lport and port_id as parameters. Use this in fc_rport_recv_plogi_req() and fc_rport_recv_logo_req(). Signed-off-by:

alua_activate only sends a STPG if only explicit is suppored. As a result, for EMC targets that support both we end up doing a implicit failover when X commands are finally sent to the other SP. This patch does a AND on the h->tpgs, so we do a explicit failover right away. Signed-off-by:

When using iface, bnx2i was unable to offload further connections after all active sessions are logged out. bnx2i will unregister the device from cnic when the last connection is torn down. Next call to ep_connect() will fail because the device is not registered. This issue is not seen if shost == NULL is passed to ep_connect() call because in that case bnx2i will registers all known devices with cnic before doing a route look-up. When shost != NULL, bnx2i knows the device on which to offload the connection and has to register this device before attempting to offload the connection Signed-off-by:

In commit a8e7d49a ("Fix race in create_empty_buffers() vs __set_page_dirty_buffers()"), I removed a test for a NULL page mapping unintentionally when some of the code inside __set_page_dirty() was moved to the callers. That removal generally didn't matter, since a filesystem would serialize truncation (which clears the page mapping) against writing (which marks the buffer dirty), so locking at a higher level (either per-page or an inode at a time) should mean that the buffer page would be stable. And indeed, nothing bad seemed to happen. Except it turns out that apparently reiserfs does something odd when under load and writing out the journal, and we have a number of bugzilla entries that look similar: http://bugzilla.kernel.org/show_bug.cgi?id=13556 http://bugzilla.kernel.org/show_bug.cgi?id=13756 http://bugzilla.kernel.org/show_bug.cgi?id=13876 and it looks like reiserfs depended on that check (the common theme seems to be "data=journal", and a journal writeback during a truncate). I suspect reiserfs should have some additional locking, but in the meantime this should get us back to the pre-2.6.29 behavior. Pattern-pointed-out-by:
