Re: Understanding Linux addr space, malloc, and heap

I guess I live in a different world. I do lots of things I'm not "supposed" to do.

Moreover, it is very sensible and usable to mprotect malloc pages. I have implemented simple sandboxing this way. For my dissertation I implemented a DSM by mprotect'g malloc'd memory. This system worked for >6 on several version of Linux and SunOS. I actually have a better track record for this technique than for some things that are within the specifications.

The point of the code is to show that one can protect malloc code.

You "can" do many things.  But that does not mean that you always get any
sensible behaviour.
