The Sentry intercepts the untrusted code’s syscalls and handles them in user-space. It reimplements around 200 Linux syscalls in Go, which is enough to run most applications. When the Sentry actually needs to interact with the host to read a file, it makes its own highly restricted set of roughly 70 host syscalls. This is not just a smaller filter on the same surface; it is a completely different surface. The failure mode changes significantly. An attacker must first find a bug in gVisor’s Go implementation of a syscall to compromise the Sentry process, and then find a way to escape from the Sentry to the host using only those limited host syscalls.
