Introduction. (skip to the question please ;)
There was a time when a program can do the things in a way I like her to do them. Some time passed, I have found that I can't do some of them any more. I hope there is a way still, though..
Maybe there are options in compiler, maybe in loader, maybe in kernel (I'm interested in Linux OS, newbie in it, though), have no idea where; but sorry - I don't want to end up as dead while searching..
The question.
I want to run a code in a program that has been modified by that program (producing assembler instructions). Tried it - got the SIGSEGV as result of changing the immediate data in the code segment. I need a way to make the code segment writable etc, ONLY for my own USER-space program. Where to start?
Thanks.
P.S. As suggested tags were c++/linux/c, added them.
