Disallow kernel space memory access when unprivileged.
2009-09-03 Dave Brolley <brolley@redhat.com>
* runtime/addr-map.c (lookup_addr_aux): Now takes size argument.
Consider the size when looking for overlapping range with the map
entries.
(lookup_bad_addr): Now takes size argument. Disallow kernel space access
when STP_PRIVILEGED is not defined. Pass size to lookup_addr_aux.
<asm/processor.h>: #include it when STP_PRIVILEGED is not defined.
(add_bad_addr_entry): Supply a size of 1 to calls to lookup_addr_aux.
* runtime/loc2c-runtime.h (kread): Pass sizeof (*(ptr)) to
lookup_bad_addr.
(kwrite): Likewise.
(deref): Pass size to lookup_bad_addr.
(store_deref): Likewise.
