* [SCSI] iscsi_tcp: convert to new alloc_hdr apiMike Christie2008-12-29

* [SCSI] libiscsi: prepare libiscsi for new offload engines by modifying unsol ↵Mike Christie2008-12-29
| | | | | | | | | | | | | data code cxgb3i offloads data transfers. It does not offload the entire scsi/iscsi procssing like qla4xxx and it does not offload the iscsi sequence processing like how bnx2i does. cxgb3i relies on iscsi_tcp for the seqeunce handling so this changes how we transfer unsolicitied data by adding a common r2t struct and helpers.

* [SCSI] iscsi_tcp: prepare helpers for LLDs that can offload some operationsMike Christie2008-12-29
| | | | | | | | | | | | | cxgb3i is unlike qla4xxx and bnx2i in that it does not offload entire scsi commands or iscsi sequences. Instead it only offloads the transfer of a ISCSI DATA_IN pdu's data, the digests and padding. This patch fixes up the iscsi tcp recv path so that it exports its skb recv processing so cxgb3i and other drivers can call them. All they have to do is pass the function the skb with the hdr or data pdu header and this function will do the rest.

* [SCSI] st: update to use block timeoutJames Bottomley2008-12-29
| | | | | | | | | | | Since we're trying to eliminate struct scsi_device timeout, the tape driver has to be updated to use the block queue timeout instead. The tape use of scsi_device timeout looks to be self consistent, so I don't think this necessarily fixes any bug, but it has to be done to allow me to remove the timeout parameter from struct scsi_device.

* [SCSI] mac_esp: fix for quadras with two esp chipsFinn Thain2008-12-29
| | | | | | | | | | | | On the Quadra 900 and 950 there are two ESP chips sharing one IRQ. Because the shared IRQ is edge-triggered, we must make sure that an IRQ transition from one chip doesn't go unnoticed when the shared IRQ is already active due to the other. This patch prevents interrupts getting lost so that both SCSI busses may be used simultaneously.

* [SCSI] simplify scsi_io_completion()Alan Stern2008-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1142b) consolidates a lot of repetitious code in scsi_io_completion(). It also fixes a few comments. Most importantly, however, it clearly distinguishes among the three sorts of retries that can be done when a command fails to complete: Unprepare the request and resubmit it, so that a new command will be created for it. Requeue the request directly so that it will be retried immediately using the same command. Requeue the request so that it will be retried following a short delay. Complete the remainder of the request with an I/O error. [jejb: Updates 1. For several error conditions, we would now print the sense twice in slightly different ways, so unify the location of sense printing. 2. I added more descriptions to actual failure conditions for better debugging 3. according to spec, ABORTED_COMMAND is supposed to be retried (except on DIF failure). Our old behaviour of erroring it looks to be a bug. 4. I'd prefer not to default initialise the action variable because that ensures that every leg of the error handler has an associated action and the compiler will warn if someone later accidentally misses one or removes one. ] Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

* [SCSI] ibmvfc: Fix command timeouts due to cached CRQ accessBrian King2008-12-29
| | | | | | | | | | | | | The CRQs used by the ibmvfc driver are read and written by both the client and the server. Therefore, we need to mark them volatile so that we do not cache their contents when handling an interrupt. This fixes a problem which can surface as occasional command timeouts. No commands were actually timing out, but due to accessing cached data for the CRQ in the interrupt handler, the interrupt was not processing all command completions as it should.

* [SCSI] scsi_error: TASK ABORTED status handling improvementVladislav Bolkhovitin2008-12-29
| | | | | | | | | | | | | | | | | | | | | This patch improves handling of TASK ABORTED status by Linux SCSI mid-layer. Currently, command returned with this status considered failed and returned to upper layers. It leads to additional error recovery load on file systems and block layer, which sometimes can cause undesired side effects, like I/O errors and file systems corruptions. See http://lkml.org/lkml/2008/11/1/38, for instance. From other side, TASK ABORTED status is returned by SCSI target if the corresponding command was aborted by another initiator and the target has TAS bit set in the control mode page. So, in the majority of cases commands with TASK ABORTED status should be simply retried. In other cases, maybe_retry path will not retry if no retries are allowed. This patch implement suggestion by James Bottomley from http://marc.info/?l=linux-scsi&m=121932916906009&w=2.

* [SCSI] ibmvfc: Fix target initialization failure retry handlingBrian King2008-12-29
| | | | | | | | | | | | | | | | If the ibmvfc driver is in discovery attempting to log into a target and it encounters an error, the command may get retried one or more times, depending on the error received. If the retries are unsuccessful such that the discovery thread gives up on discovery to that target, the target ends up in a state where, if SCSI core had previously known about the device, the host will get unblocked but the host will not be logged into the target, causing any commands sent to the target to fail. This patch fixes this so that if this occurs, the target is deleted such that the normal dev_loss processing can occur instead.

* [SCSI] ibmvfc: Error handling fixesBrian King2008-12-29
| | | | | | | | | | | | | | | Due to an ambiguity in the VIOS VFC interface specification, abort/cancel handling is not done correctly and can result in double completion of commands. In order to cancel all outstanding commands to a device, a cancel must be sent, followed by an abort task set. After the responses are received for these commands, there may still be commands outstanding, in the process of getting flushed back, in which case, we need to wait for them. This patch removes the assumption that if the abort and the cancel both complete successfully that the device queue has been flushed and waits for all the responses to come back.

| * | | | | | [SCSI] libiscsi REGRESSION: fix passthrough support with older iscsi toolsMike Christie2008-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This regression was added in 2.6.27, when the mtask and ctask were merged into the the common task struct. The patch applies to scsi-rc-fixes, but also applies to 2.6.27 with some offsets. The problem is that __iscsi_conn_send_pdu assumes that userspace was not sending nops with the format it is checking for in the "if" below. It turns out that older userspace tools are. This patch moves the setting of the internal ping_task tracker (it tracks libiscsi current outstanding nop) to iscsi_send_nopout which is only used by kernel callers.

With this patch in place, the system is booting reliably. Mike Anderson found the same problem in the hp_hw_start_stop code, and I applied the same solution in cdrom_read_cdda_bpc.
