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 permissions 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 messagehelp
