* [SCSI] ibmvfc, qla2xxx, lpfc: remove scsi_target_unblock calls in terminate ↵Mike Christie2008-10-131-2/+0

* block: unify request timeout handlingJens Axboe2008-10-091-1/+1
| | | | | | | | | | | | | Right now SCSI and others do their own command timeout handling. Move those bits to the block layer. Instead of having a timer per command, we try to be a bit more clever and simply have one per-queue. This avoids the overhead of having to tear down and setup a timer for each command, so it will result in a lot less timer fiddling.

* [SCSI] ibmvfc: Fix for lost async eventsBrian King2008-08-161-7/+11
| | | | | | | | | | | If the client virtual fibre channel adapter is already logged into the server and does an NPIV Login again, the async queue, which is used for reporting Link Up/Link Down type of events, does not get reset on the server side. Fix up the client driver so that we also do not reset it. This fixes a problem of lost async events following relogins.

* [SCSI] ibmvfc: Fixup host state during reinitBrian King2008-08-161-1/+2
| | | | | | | | | | | | | | If an ELS is received while the virtual fibre channel adapter is going through its discovery, a flag is set which causes discovery to get re-driven. However, the hosts's state does not get set back to IBMVFC_INITIALIZING and scsi_block_requests does not get called again, which can result in queuecommand ops getting sent during discovery. This should not occur and may cause problems. One example is that we may no longer be logged into the target we send the command to, resulting in a failure which should not have occurred.

* [SCSI] ibmvfc: Fix another hang on module removalBrian King2008-08-161-3/+4
| | | | | | | | | | | | This fixes a hang on module removal. The module removal code was setting the hosts's state to IBMVFC_HOST_OFFLINE before tearing down the kernel thread, but, due to a bug in ibmvfc_wait_while_resetting, was not waiting for the kernel thread's offlining work to be done prior to destroying the kernel thread, which left the scsi host in a blocked state which we never got out of.

* | dma-mapping: add the device argument to dma_mapping_error()FUJITA Tomonori2008-07-264-6/+6
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add per-device dma_mapping_ops support for CONFIG_X86_64 as POWER architecture does: This enables us to cleanly fix the Calgary IOMMU issue that some devices are not behind the IOMMU (http://lkml.org/lkml/2008/5/8/423). I think that per-device dma_mapping_ops support would be also helpful for KVM people to support PCI passthrough but Andi thinks that this makes it difficult to support the PCI passthrough (see the above thread). So I CC'ed this to KVM camp. Comments are appreciated. A pointer to dma_mapping_ops to struct dev_archdata is added. If the pointer is non NULL, DMA operations in asm/dma-mapping.h use it. If it's NULL, the system-wide dma_ops pointer is used as before. If it's useful for KVM people, I plan to implement a mechanism to register a hook called when a new pci (or dma capable) device is created (it works with hot plugging). It enables IOMMUs to set up an appropriate dma_mapping_ops per device. The major obstacle is that dma_mapping_error doesn't take a pointer to the device unlike other DMA operations. So x86 can't have dma_mapping_ops per device. Note all the POWER IOMMUs use the same dma_mapping_error function so this is not a problem for POWER but x86 IOMMUs use different dma_mapping_error functions. The first patch adds the device argument to dma_mapping_error. The patch is trivial but large since it touches lots of drivers and dma-mapping.h in all the architecture. This patch: dma_mapping_error() doesn't take a pointer to the device unlike other DMA operations. So we can't have dma_mapping_ops per device. Note that POWER already has dma_mapping_ops per device but all the POWER IOMMUs use the same dma_mapping_error function. x86 IOMMUs use device argument.

* [SCSI] Let scsi_cmnd->cmnd use request->cmd bufferBoaz Harrosh2008-05-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - struct scsi_cmnd had a 16 bytes command buffer of its own. This is an unnecessary duplication and copy of request's cmd. It is probably left overs from the time that scsi_cmnd could function without a request attached. So clean that up. - Once above is done, few places, apart from scsi-ml, needed adjustments due to changing the data type of scsi_cmnd->cmnd. - Lots of drivers still use MAX_COMMAND_SIZE. So I have left that #define but equate it to BLK_MAX_CDB. The way I see it and is reflected in the patch below is. MAX_COMMAND_SIZE - means: The longest fixed-length (*) SCSI CDB as per the SCSI standard and is not related to the implementation. BLK_MAX_CDB. - The allocated space at the request level - I have audit all ISA drivers and made sure none use ->cmnd in a DMA Operation. Same audit was done by Andi Kleen. (*)fixed-length here means commands that their size can be determined by their opcode and the CDB does not carry a length specifier, (unlike the VARIABLE_LENGTH_CMD(0x7f) command). This is actually not exactly true and the SCSI standard also defines extended commands and vendor specific commands that can be bigger than 16 bytes. The kernel will support these using the same infrastructure used for VARLEN CDB's. So in effect MAX_COMMAND_SIZE means the maximum size command scsi-ml supports without specifying a cmd_len by ULD's Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

| | | | | | | | | | | | | | | | | | | | | | | | CRQ send errors that return with H_CLOSED should return with SCSI_MLQUEUE_HOST_BUSY until firmware alerts the client of a CRQ transport event. The transport event will either reinitialize and requeue the requests or fail and return IO with DID_ERROR. To avoid failing the eh_* functions while re-attaching to the server adapter this will retry for a period of time while ibmvscsi_send_srp_event returns SCSI_MLQUEUE_HOST_BUSY. In ibmvscsi_eh_abort_handler() the loop includes the search of the event list. The lock on the hostdata is dropped while waiting to try again after failing ibmvscsi_send_srp_event. The event could have been purged if a login was in progress when the function was called. In ibmvscsi_eh_device_reset_handler() the loop includes the call to get_event_struct() because a failing call to ibmvscsi_send_srp_event() will have freed the event struct.

If this was not an initial login, but was a login after a disconnect with the server, other I/O requests could attempt to be processed before the login occured. These I/O requests would fail, sometimes resulting in filesystems getting marked read-only. To address this we can set the request_limit to 0 while doing the login and add an exception where login requests, along with task management events, are always passed to the server. There is a case where the request_limit had already reached 0 would result in all events being sent rather than returning SCSI_MLQUEUE_HOST_BUSY; this has also been fixed by this patch.

* [SCSI] ibmvscsi: Abort path fixBrian King2007-06-171-1/+1
| | | | | | | | | Since it is completely possible for scsi core to call a LLDD's eh_abort function after the command has completed, fix ibmvscsi to return SUCCESS if this is the case. Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] ibmvscsi: Misc. locking fixesBrian King2007-06-171-0/+6
| | | | | | | | | | Fix a couple locking bugs discovered during code inspection. ibmvscsi_send_srp_event needs to be called with the host lock held. This patch fixes a couple paths in the code where this wasn't true. Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] ibmvscsi: Add eh_host_reset_handlerBrian King2007-06-172-30/+107
| | | | | | | | | | | Adds an eh_host_reset_handler to ibmvscsi which resets the connection to the vscsi server. This patch also adds a timer to internally issues commands to prevent client hangs in the case of a misbehaving server. Tested by modifying the VIOS such that it would occasionally drop one or more request in sequence.
