Is it possible to code smc code inside the ".text"-segment without the use of the ".bss"-segment? I've been experimenting with it, but mprotect fails with error code 11 (EAGAIN) when trying. After some googling and checking man pages, it seems it's not possible to do mprotect anymore on non memory mapped memory? If this is the case, since when doesn't this work? And is there any work around for it?

Thanks for any responses

Nevermind, it seems I've been debugging all for nothing. The kernel gives EAGAIN error, but the syscalls succeeds anyhow.

Hence why I put the names within quotation. I figured it would be easier to understand what I meant by putting the section names to describe what segments I meant.

Asmcoder just teases you . You know, segment is not equal to section.
Nevertheless, would you be so kind to attach your sm code here? We'd all like to learn something from your solved problem. Otherwise this thread doesn't make too much sense.
