Library-based Compartmentalisation on CHERI
Existing software compartmentalisation solutions tend to incur considerable performance or refactoring costs. And it seems difficult, at least on conventional hardware, to reach the sweet spot of simultaneously having \emph{low overhead}, \emph{wide applicability}, and \emph{easy migration}. This article presents early results indicating that such a sweet spot can be reached on a CHERI-enabled architecture. Our key contributions are a) a \emph{compartmentalisation model} based on dynamic linkage and b) a prototype implementation of the model on Morello, a high-performance AArch64 CPU extended with CHERI.
