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.
Recent history, both the failure of Concord and the ongoing struggles of Highguard, serves as a testament to how hard it is to launch a live service game in the 2020s. Full Circle's announcement notes the "tens of millions" of players that have tried the new game, but it's possible a struggle to keep players interested and spending on microtransactions could be why it's restructuring.
