The final line of /proc/<pid>/maps on x86_64 for native 64-bit tasks shows an incorrect ending address and incorrect permissions. There is only a single page mapped in this vsyscall region, and it is accessible for both read and execute. The patch below fixes this. (Since 32-bit-compat tasks have a real vma with correct perms/range, no change is necessary for that scenario.) Before the patch, a "cat /proc/self/maps | tail -1" shows this: ffffffffff600000-ffffffffffe00000 ---p 00000000 [...] After the patch, this is the output: ffffffffff600000-ffffffffff601000 r-xp 00000000 [...] Signed-off-by: Ernie Petrides <petrides@redhat.com> Signed-off-by: Andi Kleen <ak@suse.de> |
