I see why FreeBSD doesn't have a non-executable stack and heap, mainly because ia32 don't devide read and execute permissions, but it would be nice for a program to chose if it's stack (and heap) should be executable or having the option to make ALL stacks non-executable. Does ia64 fix the problem with read/execute permissions, so we can make a syscall to limit stack-based overflows? br socketd To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
