-Subject: x86/ioreq server: correctly handle bogus
- XEN_DMOP_{,un}map_io_range_to_ioreq_server arguments
-
-Misbehaving device model can pass incorrect XEN_DMOP_map/
-unmap_io_range_to_ioreq_server arguments, namely end < start when
-specifying address range. When this happens we hit ASSERT(s <= e) in
-rangeset_contains_range()/rangeset_overlaps_range() with debug builds.
-Production builds will not trap right away but may misbehave later
-while handling such bogus ranges.
-
-This is XSA-238.
