2006-09-23[SCSI] zfcp: fix: avoid removal of fsf reqs before qdio queues are downAndreas Herrmann
Fix the fix ... One of my previous fixes introduced removal of all fsf requests in zfcp's eh_host_reset_handler. But this must not happen before qdio queues are shut down. So, I revert the changes of zfcp_scsi_eh_host_reset_handler. Signed-off-by: Andreas Herrmann <aherrman@de.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2006-09-23[SCSI] zfcp: fix: use correct req_id in eh_abort_handlerAndreas Herrmann
zfcp's eh_abort_handler used the wrong request ID to identify the request to be aborted. The bug was introduced with commit fea9d6c7bcd8ff1d60ff74f27ba483b3820b18a3 for improved management of request IDs. The bug is fixed with this patch.

Create private slab caches in order to guarantee proper alignment of data structures that get passed to hardware.

2006-09-23[SCSI] aic7xxx: pause sequencer before touching SBLKCTLDoug Ledford
Some cards need to pause the sequencer before the SBLKCTL register is touched. This fixes a PCI related oops seen on powerpc macs with this card caused by trying to ascertain the bus signalling before beginning domain validation. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-09-23[SCSI] aic7xxx: avoid checking SBLKCTL register for certain cardsJames Bottomley
For cards that don't support LVD, checking the SBLKCTL register to determine the bus singalling doesn't work. So, check that the card supports LVD first (AHC_ULTRA2) before checking the register. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-09-23[SCSI] scsi_debug version 1.80Douglas Gilbert
See http://www.torque.net/sg/sdebug26.html for more information on the scsi_debug driver. ChangeLog: - add 'vpd_use_hostno' parameter to allow simulated hosts to see the same set of targets (and luns). For testing multipath software. - add 'fake_rw' parameter to ignore the data in READ and WRITE commands - add support for log subpages (new in SPC-4) - yield appropriate block descriptor for MODE SENSE commands (only for pdt=0 (i.e. disks)) - REQUEST SENSE response no longer shows the stopped power condition (SAT changed to agree with SPC-3) Signed-off-by: Douglas Gilbert <dougg@torque.net> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2006-09-22IPoIB: Rejoin all multicast groups after a port eventEli Cohen
When ipoib_ib_dev_flush() is called because of a port event, the driver needs to rejoin all multicast groups, since the flush will call ipoib_mcast_dev_flush() (via ipoib_ib_dev_down()). Otherwise no (non-broadcast) multicast groups will be rejoined until the networking core calls ->set_multicast_list again, and so multicast reception will be broken for potentially a long time.

2006-09-22IPoIB: Create MCGs with all attributes required by RFCRoland Dreier
RFC 4391 ("Transmission of IP over InfiniBand (IPoIB)") says: If the IB multicast group does not already exist, one must be created first with the IPoIB link MTU. The MGID MUST use the same P_Key, Q_Key, SL, MTU, and HopLimit as those used in the broadcast-GID. The rest of attributes SHOULD follow the values used in the broadcast-GID as well. However, the current IPoIB driver is only setting the attributes required by the InfiniBand spec to create a multicast group, so in particular the MTU and HopLimit are not being set. Add these attributes when creating MCGs, and also set the Rate attribute, since IPoIB pays attention to that attribute as well. Signed-off-by: Roland Dreier <rolandd@cisco.com>

2006-09-22IB/mthca: Simplify calls to mthca_cq_clean()Roland Dreier

2006-09-22IB/iser: Do not use FMR for a single dma entry sgErez Zilber
Fast Memory Registration (fmr) is used to register for rdma an sg whose elements are not linearly sequential after dma mapping. The IB verbs layer provides an "all dma memory MR (memory region)" which can be used for RDMA-ing a dma linearly sequential buffer.

2006-09-22IB/iser: make FMR "page size" be 4K and not PAGE_SIZEErez Zilber
As iser is able to use at most one rdma operation for the execution of a scsi command, and registration of the sg associated with scsi command has its restrictions, the code checks if an sg is "aligned for rdma". Alignment for rdma is measured in "fmr page" units whose possible resolutions are different between HCAs and can be smaller, equal or bigger to the system page size. When the system page size is bigger than 4KB (eg the default with ia64 kernels) there a bigger chance that an sg would be aligned for rdma if the fmr page size is 4KB. Change the code to create FMR whose pages are of size 4KB and to take that into account when processing the sg.

2006-09-22IB/iser: Limit the max size of a scsi commandErez Zilber
Currently, the data length of a command coming down from scsi-ml is limited only by the size of its sg list (sg_tablesize). The max data length may be different for different page size values. By setting max_sectors, we limit the data length to max_sectors*512 bytes. Signed-off-by: Erez Zilber <erezz@voltaire.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
