"Add a possibility to add a random offset to the stack on exec. This makes it slightly harder to write generic buffer overflows. This doesn't really give any real security, but it raises the bar for script-kiddies and it's really cheap.
This idea can also be used within applications. Just use alloca(<random value>) to randomize the stack location. No kernel changes needed. There are more portable ways to do this, of course, for those who dislike alloca.
