The second setting is Supervisor Mode Access Prevention (SMAP) (CR4.SMAP). Its full description in Volume 3, Section 4.6 is verbose, but the executive summary is that SMAP disables the kernel’s ability to read or write userspace memory entirely.

The key to this approach is something alluded to in my post on continuation-passing style: We can write code which simulates the call stack of the language we’re working in by representing stack frames as first-class values. That post does so in a functional context, unlocking superpowers like simulated resumable exceptions by choosing CPS functions as our representation. In this post we’ll do so in an imperative context, using mutable records to work around the limitations of our language runtime.
