* [SCSI] update fc_transport for removal of block/unblock functionsJames.Smart@Emulex.Com2005-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We recently went back to implement a board reset. When we perform the reset, we wanted to tear down the internal data structures and rebuild them. Unfortunately, when it came to the rport structure, things were odd. If we deleted them, the scsi targets and sdevs would be torn down. Not a good thing for a temporary reset. We could block the rports, but we either maintain the internal structures to keep the rport reference (perhaps even replicating what's in the transport), or we have to fatten the fc transport with new search routines to find the rport (and deal with a case of a dangling rport that the driver forgets). It dawned on me that we had actually reached this state incorrectly. When the fc transport first started, we did the block/unblock first, then added the rport interface. The purpose of block/unblock is to hide the temporary disappearance of the rport (e.g. being deleted, then readded). Why are we making the driver do the block/unblock ? We should be making the transport have only an rport add/delete, and the let the transport handle the block/unblock. So... This patch removes the existing fc_remote_port_block/unblock functions. It moves the block/unblock functionality into the fc_remote_port_add/delete functions. Updates for the lpfc driver are included. Qlogic driver updates are also enclosed, thanks to the contributions of Andrew Vasquez. [Note: the qla2xxx changes are relative to the scsi-misc-2.6 tree as of this morning - which does not include the recent patches sent by Andrew]. The zfcp driver does not use the block/unblock functions. One last comment: The resulting behavior feels very clean. The LLDD is concerned only with add/delete, which corresponds to the physical disappearance. However, the fact that the scsi target and sdevs are not immediately torn down after the LLDD calls delete causes an interesting scenario... the midlayer can call the xxx_slave_alloc and xxx_queuecommand functions with a sdev that is at the location the rport used to be. The driver must validate the device exists when it first enters these functions. In thinking about it, this has always been the case for the LLDD and these routines. The existing drivers already check for existence. However, this highlights that simple validation via data structure dereferencing needs to be watched. To deal with this, a new transport function, fc_remote_port_chkready() was created that LLDDs should call when they first enter these two routines. It validates the rport state, and returns a scsi result which could be returned. In addition to solving the above, it also creates consistent behavior from the LLDD's when the block and deletes are occuring.

* [SCSI] lpfc driver 8.0.30 : dev_loss and nodev timeoutsJames.Smart@Emulex.Com2005-08-12
| | | | | | | | | | | | | | | | | | | | Fix handling of the dev_loss and nodev timeouts. Symptoms: when remote port disappears for a period of time longer then either nodev_tmo or dev_loss_tmo, the lpfc driver worker thread will stall removing that remote port. Cause: removing remote port involves un-blocking and sync-ing corresponding block device queue. But corresponding node in the lpfc driver is still in the NPR(?node port recovery?) state and mid-layer gets SCSI_MLQUEUE_HOST_BUSY as a return value when it is trying to call queuecommand() with command for that node (AKA remote port) Fix: Instead of returning SCSI_MLQUEUE_HOST_BUS from queuecommand() for nodes in NPR states complete it with retry-able error code DID_BUS_BUSY Signed-off-by: James Smart <James.Smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* [SCSI] lpfc: Fixes in mbox_timeout_handlerJames.Smart@Emulex.Com2005-07-02
| | | | | | | | | | | | | | | | | | | Analysis: Timeout of READ_SPARM64 causes call to lpfc_mbox_timeout_handler which reads psli->mbox_active to determine the timeout mbox. Timeout handler then NULL's psli->mbox_active and calls lpfc_mbx_cmpl_read_sparam(), which on timeout condition, calls link_down(). link_down() now calls disc_done() which calls mbox_timeout_hander() again since WORKER_MBOX_TMO is still set, which goes back to read psli->mbox_active which is already NULL'ed. Remove redundant if statement in lpfc_mbox_timeout_handler. pmbox is assigned psli->mbox_active so there is no need to check if it actually equals psli->mbox_active.
