I hope there are OS level (ie kernel build options) to turn this kind of thing off or just ignore the 'tags'. I know it's important for corporate use cases and monetary transactions and all that, but on my personal computer I use for fun I want to be able to peek and poke.
- tredre3 1y agoIf you're worried that this is going to prevent you from peeking and poking, I think you're mistaken. This is to protect a process against itself, not the outside. It will also likely be a single bit flip away of being unenforced at runtime, as most x86 protections already are to be to make debugging tools feasible. By the way, there are already systems in place to prevent you from accessing certain memory zones. Yes, even on Linux, it's possible to make memory regions inaccessible even to root or the kernel itself. The time to be worried about that was 10 years ago.

- superkuh 1y agoI have a patch set to removes virtual memory interprocess blocking for linux 5.6 that I run as kernel on a couple of my machines. I'm just hoping that this is patchable out too.
