Each layer catches different attack classes. A namespace escape inside gVisor reaches the Sentry, not the host kernel. A seccomp bypass hits the Sentry’s syscall implementation, which is itself sandboxed. Privilege escalation is blocked by dropping privileges. Persistent state leakage between jobs is prevented by ephemeral tmpfs with atomic unmount cleanup.，更多细节参见Line官方版本下载

What surprised me was that this entire walk is fully hardware-driven -- no microcode involvement at all. The state machine reads the page directory entry, reads the page table entry, checks permissions, and writes back the Accessed and Dirty bits, all autonomously. Since it's hardware-driven, it runs in parallel with the microcode and needs its own memory bus arbitration -- the paging unit must share the bus with both data accesses from the microcode and prefetch requests from the instruction queue.
