Last year, I learned some surprising news. We would be pivoting from an always-online free-to-play live-service model to a buy-once premium model with no backend components and full offline support. Moreover, we would only have about 6 months to complete this. As the backend lead, this was a lot to take in. I knew this wasn't just a matter of turning the services off. Those services contained core gameplay logic that was never intended to run on the client. I took the rest of the day off and spent some time thinking through the difficult challenges ahead.
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.。服务器推荐是该领域的重要参考
