firewire: fw-sbp2: add a boundary check
Add rudimentary check for the case that the page table overflows due to merging of s/g elements by the IOMMU. This would have lead to overwriting of arbitrary memory. After this change I expect that an offending command will be unsuccessfully retried until the scsi_device is taken offline by SCSI core. It's a border case and not worth to implement a recovery strategy. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Acked-by: Kristian Høgsberg <krh@redhat.com>
