Or Gerlitz 7ecc5d44a8 IB/iser: Rewrite SG handling for RDMA logic ... commit c1ccaf2478 upstream. After dma-mapping an SG list provided by the SCSI midlayer, iser has to make sure the mapped SG is "aligned for RDMA" in the sense that its possible to produce one mapping in the HCA IOMMU which represents the whole SG. Next, the mapped SG is formatted for registration with the HCA. This patch re-writes the logic that does the above, to make it clearer and simpler. It also fixes a bug in the being aligned for RDMA checks, where a "start" check wasn't done but rather only "end" check. [commit message in RH kernel tree: "Under heavy load, without the patch, the HCA can be programmed to write (corrupt) into pages/location which doesn't belong to the SG associated with the actual I/O and cause a kernel oops."] Signed-off-by: Alexander Nezhinsky <alexandern@voltaire.com> Signed-off-by: Or Gerlitz <ogerlitz@voltaire.com> Signed-off-by: Roland Dreier <rolandd@cisco.com> Cc: maximilian attems <max@stro.at> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>		2010-04-26 07:41:36 -07:00
