Text segment is READONLY… Wait, what? Who said that? Modern Linux kernel uses self modifying code a lot. And that’s not only about modules loading.During this talk, we’ll look at how different kinds of self modifying code are used in Linux kernel to extend functionality, assist in debugging, workaround hardware bugs, mitigate vulnerabilities and simply making kernel faster.However rewriting code has its price which turns into increasing system complexity. I’ll talk about it based on my experience with implementation of static branches for ARC architecture.PS: don’t rewrite yourself.»NOTE«: ‘Salon Pasteur’ room isn’t showed on the map - it is near the main registration area. Just go to the registration and ask them :)
