* [SCSI] sd: fix bug in SCSI async probingJames Bottomley2009-06-08
| | | | | | | | | | The async split up of probing in sd.c created a potential failure case where something goes wrong with device_add(), but which we don't recover properly. Since, in general, asynchronous error handling is hard, move the device_add() into the asynchronous path (it should be fast) and make sure all the deferred processing cannot fail.

* [SCSI] fix up scsi_eh_lock_door()James Bottomley2009-06-08

* [SCSI] lpfc 8.3.2 : Reorganization for SLI4James Smart2009-06-08
| | | | | | | | | | | | | | | Preps the organization of the driver so that the bottom half, which interacts with the hardware, can share common code sequences for attachment, detachment, initialization, teardown, etc with new hardware. For very common code sections, which become specific to the interface type, the driver uses an indirect function call. The function is set at initialization. For less common sections, such as initialization, the driver looks at the interface type and calls the routines relative to the interface.

* [SCSI] libiscsi: don't let io sit in queue when session has failedMike Christie2009-05-23
| | | | | | | | | | | | | If the session is failed, but we have not yet fully transitioned to the recovery stage we were still queueuing IO. The idea is that for some failures we can recvover at the command level and still continue to execute other IO. Well, we never have added the recovery within a command code, so queueing up IO here just creates the possibility that it might time time out so this just has us requeue the IO the scsi layer for now.

* [SCSI] libiscsi: handle cleanup task racesMike Christie2009-05-23
| | | | | | | | | | | | | | | | | | | | | | | bnx2i needs to send a hardware specific cleanup command if a command has not completed normally (iscsi/scsi response from target), and the session is still ok (this is the case when we send a TMF to stop the command). At this time it will need to drop the session lock. The problem with the current code is that fail_all_commands assumes we will hold the lock the entire time, so it uses list_for_each_entry_safe. If while bnx2i drops the session lock multiple cmds complete then list_for_each_entry_safe will not handle this correctly. This patch removes the running lists and just has us loop over the cmds array (in later patches we will then replace that array with a block tag map at the session level). It also fixes up the completion path so that if the TMF code and the normal recv path were completing the same command then they both do not try to do release the refcount taken when the task is queued.

* [SCSI] libiscsi: fix iscsi transport checks to account for slower linksMike Christie2009-05-23
| | | | | | | | | | | | | | If we have not got any pdus for recv_timeout seconds, then we will send a iscsi ping/nop to make sure the target is still around. The problem is if this is a slow link, and the ping got queued after the data for a data_out (read), then the transport code could think the ping has failed when it is just slowly making its way through the network. This patch has us check if we are making progress while the nop is outstanding. If we are still reading in data, then we do not fail the session at that time.

* [SCSI] libiscsi_tcp: update recv tracking for each skb instead of iscsi pduMike Christie2009-05-23
| | | | | | | | | | | | | | | | | | | | Everytime we read in a pdu libiscsi will update a tracking field. It uses this to decide when to check if the transport might be bad. If we have not got data in recv_timeout seconds then we will send a iscsi ping/nop. If we are on a slow link then it could take a while to read in all the data for a data_in. In that case we might send a ping/nop when we do not need to or we might drop a session thinking it is bad when the lower layer is making forward progress on it. This patch has libiscsi_tcp update the recv tracking for each skb (basically network packet from our point of view) instead of the entire iscsi pdu+data, so we account for these cases where data is coming in slowly.

* [SCSI] libiscsi: fix nop response/reply and session cleanup raceMike Christie2009-05-23
| | | | | | | | | | | | | | | | If we are responding to a nop from the target by sending our nop, and the session is getting torn down, then iscsi_start_session_recovery could set the conn stop bits while the recv path is sending the nop response and we will hit the bug ons in __iscsi_conn_send_pdu. This has us check the state in __iscsi_conn_send_pdu and fail all incoming mgmt IO if we are not logged in and if the pdu is not login related. It also changes the ordering of the setting of conn stop state bits so they are set after the session state is set (both are set under the session lock).

| | | | | | | | | | | | | | | | | | | | When we create the tcp/ip connection by calling ep_connect, we currently just go by the routing table info. I think there are two problems with this. 1. Some drivers do not have access to a routing table. Some drivers like qla4xxx do not even know about other ports. 2. If you have two initiator ports on the same subnet, the user may have set things up so that session1 was supposed to be run through port1. and session2 was supposed to be run through port2. It looks like we could end with both sessions going through one of the ports. Fixes for cxgb3i from Karen Xie.

* [SCSI] ipr: fix PCI permanent error handlerKleber S. Souza2009-05-23
| | | | | | | | | | | | | | | | | | The ipr driver can hang if it encounters enough PCI errors to trigger the permanent error handler. The driver will attempt to initiate a "bringdown" of the adapter and fail all pending ops back. However, this bringdown is unlike any other bringdown of the adapter in the code as the driver. In this code path we end up failing back ops with allow_cmds still set to 1. This results in some commands, the HCAM commands in particular, getting immediately re-issued to the adapter on the done call, which results in an infinite loop in ipr_fail_all_ops. Fix this by setting allow_cmds to zero in this path. Signed-off-by: Kleber S.
