Modified files:
sys/kern sysv_shm.c
Log:
shmat: If VM_PROT_READ_IS_EXEC is defined and prot includes VM_PROT_READ,
VM_PROT_EXECUTE must be added to prot before calling vm_map_find.
Without this change, an mprotect on a shmat'ed region fails (when
it shouldn't). This bug was reported Feb 28 by Brooks Davis
<brooks@one-eyed-alien.net> on -hackers.
