* [SCSI] zfcp: Rename sbal_last.Martin Peschke2008-06-05
| | | | | | | | | sbal_last is confusing, as it is not the last one actually used, but just a limit. sbal_limit is a better name.

* [SCSI] zfcp: Fix mempool pointer for GID_PN request allocationChristof Schmitt2008-06-05
| | | | | | | | | | | | | When allocating memory for GID_PN nameserver requests, the allocation function stores the pointer to the mempool, but then overwrites the pointer via memset. Later, the wrong function to free the memory will be called, since this is based on the stored pointer. Fix this by first initializing the struct and then storing the pointer.

* [SCSI] zfcp: receiving an unsolicted status can lead to I/O stallSwen Schillig2008-06-05
| | | | | | | | | | | | | | | | | Processing of an unsolicted status request can lead to a locking race of the request_queue's queue_lock during the recreation of the used up status read request while still in interrupt context of the response handler. Detaching the 'refill' of the long running status read requests from the handler to a scheduled work is solving this issue. In addition, each refill-run is trying to re-establish the full amount of status read requests, which might have failed in earlier runs.

| | | | | | | | | | | USB sometimes doesn't return an error but instead returns a residue value indicating part (or all) of the command wasn't completed. So if the driver _done() error processing indicates the command was fully processed, subtract off the residue so that this USB error gets propagated.

* [SCSI] zfcp: sysfs attributes for fabric and channel latenciesChristof Schmitt2008-06-05
| | | | | | | | | | | | | | | | | | | | | The latency information is provided on a SCSI device level (LUN) which can be found at the following location  /sys/class/scsi_device/<H:C:T:L>/device/cmd_latency  /sys/class/scsi_device/<H:C:T:L>/device/read_latency  /sys/class/scsi_device/<H:C:T:L>/device/write_latency Each sysfs attribute provides the available data: min, max and sum for fabric and channel latency and the number of requests processed. An overrun of the variables is neither detected nor treated. The file has to be read twice to make a meaningful statement, because only the differences of the values between the two reads can be used. A reset of the values can be achieved by writing to the attribute.

* [SCSI] scsi_dh: Add a single threaded workqueue for initializing pathsChandra Seetharaman2008-06-05
| | | | | | | | | | | | | | | | | | | | | | | | Before this patch set (SCSI hardware handlers), initialization of a path was done asynchronously. Doing that requires a workqueue in each device/hardware handler module and leads to unneccessary complication in the device handler code, making it difficult to read the code and follow the state diagram. Moving that workqueue to this level makes the device handler code simpler. Hence, the workqueue is moved to dm level. A new workqueue is added instead of adding it to the existing workqueue (kmpathd) for the following reasons: 1. Device activation has to happen faster, stacking them along with the other workqueue might lead to unnecessary delay in the activation of the path. 2. The effect could be felt the other way too. i.e the current events that are handled by the existing workqueue might get a delayed response.

* [SCSI] scsi_dh: Use SCSI device handler in dm-multipathChandra Seetharaman2008-06-05
| | | | | | | | | | | | | | | | | | | | | | | This patch converts dm-mpath to use scsi device handlers instead of dm's hardware handlers. This patch does not add any new functionality. Old behaviors remain and userspace tools work as is except that arguments supplied with hardware handler are ignored. One behavioral exception is: Activation of a path is synchronous in this patch, opposed to the older behavior of being asynchronous (changed in patch 07: scsi_dh: Add a single threaded workqueue for initializing a path) Note: There is no need to get a reference for the device handler module (as it was done in the dm hardware handler case) here as the reference is held when the device was first found. Instead we check and make sure that support for the specified device is present at table load time.

* [SCSI] scsi_dh: add infrastructure for SCSI Device HandlersChandra Seetharaman2008-06-05
| | | | | | | | | | | | | | | | | | | | | | Some of the storage devices (that can be accessed through multiple paths), do need some special handling for 1. Activating the passive path of the storage access. 2. Decode and handle the special sense codes returned by the devices. 3. Handle the I/Os being sent to the passive path, especially during the device probe time. when accessed through multiple paths. As of today this special device handling is done at the dm-multipath layer using dm-handlers. That works well for (1); for (2) to be handled at dm layer, scsi sense information need to be exported from SCSI to dm-layer, which is not very attractive; (3) cannot be done at all at the dm layer. Device handler has been moved to SCSI mainly to handle (2) and (3) properly.

| * l2tp: Fix possible oops if transmitting or receiving when tunnel goes downJames Chapman2008-06-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some problems have been experienced in the field which cause an oops in the pppol2tp driver if L2TP tunnels fail while passing data. The pppol2tp driver uses private data that is referenced via the sk->sk_user_data of its UDP and PPPoL2TP sockets. This patch makes sure that the driver uses sock_hold() when it holds a reference to the sk pointer. This affects its sendmsg(), recvmsg(), getname(), [gs]etsockopt() and ioctl() handlers. Tested by ISP where problem was seen. System has been up 10 days with no oops since running this patch. Without the patch, an oops would occur every 1-2 days.

I actually suspect the logic was wrong before the changes but -rc isn't the time to play with that ata_sff_sync - ensure writes hit the device Really we want an io* operation for 'is posted' eg ioisposted(ioaddr) so that we can fix the nasty delay this causes on most systems. - ata_sff_pause - 400nS delay Ensure the command hit the device and delay 400nS - ata_sff_dma_pause Ensure the I/O hit the device and enforce an HDMA1:0 transition delay. Requires altstatus register exists, BUG if not so we don't risk corruption in MWDMA modes. (UDMA the checksum will save your backside in theory) The only other complication then is devices with their own handlers. rb532 can use dma_pause but scc needs to access its own altstatus register for internal errata workarounds so directly call the drivers own altstatus function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The handling for PHY_MODE4 was originally just cloned from the Marvell proprietary driver (with their blessing). But we can do better than that. Tidy things up with some judicious mask definitions, to improve maintainability.

Also, only send uevent in case we get an EJECT_REQUEST without doing anything else. In other cases, you'll get an add/remove event because libata attaches/detaches the device. - In case of a dock event, which in turn signals an ACPI_NOTIFY_EJECT_REQUEST, immediately detach the device, because it may already have been gone * In case of an ACPI_NOTIFY_DEVICE/BUS_CHECK, evaluate _STA to check if the device has been plugged or unplugged. If plugged, hotplug it, if unplugged, just signal event to userspace (initial patch by Matthew Garrett <mjg59@srcf.ucam.org>) * Call ACPI _EJ0 for detached devices Signed-off-by: Holger Macht <hmacht@suse.de> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
