Very nice ! That's exactly what I was looking for.
But your code has a small problem. The pointer you pass to mprotect
is not aligned on a PAGESIZE (which is required by mprotect).
Here is a new version of this patch with the right alignment.
This makes -sws 0 fully working on amd64 even with NX bit enabled.
I will commit in a few days if nobody's against it.
