Hi all I just have a few question about execution of code on the stack or heap. It is possible in FreeBSD right? But why does the stack and heap need to be executable? I have read about mprotect(), but can you change the stack and heap permi= ssions with that? If yes how? (the man page tells you almost nothing). Btw does the ia32 have both read and execution permissions for the memory= or is read and execution the same? If it is the same, have this changed in ia64? Hope someone can answer these :-) br socketd To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
