Elighten me: what unused/underused safety features x86_64 has that wouldn't require the OS to have some method of using or enabling them? Why do you think mseal isn't warranted and what would be better instead?
- gcr 2y agoi read the above poster's critique about operating system and API design more generally. x86-64 can do wonderful things with memory access paradigms, why must we keep using Linux and its baked-in assumptions about how memory should work? Let's instead rewrite everything to be memory-safe, with safety enforced by everything we've learned in the last 60 years of architecture design. That's what I think the parent post is saying. (I personally gently disagree)
