Instead of filtering syscalls to the host kernel, gVisor interposes a completely separate kernel implementation called the Sentry between the untrusted code and the host. The Sentry does not access the host filesystem directly; instead, a separate process called the Gofer handles file operations on the Sentry’s behalf, communicating over a restricted protocol. This means even the Sentry’s own file access is mediated.

The tradeoff is complexity. The microcode must be carefully arranged so that the instructions in delay slots are either useful setup for both paths, or at least harmless if the redirect fires. Not every case is as clean as RETF. When a PLA redirect interrupts an LCALL, the return address is already pushed onto the microcode call stack (yes, the 386 has a microcode call stack) -- the redirected code must account for this stale entry. When multiple protection tests overlap, or when a redirect fires during a delay slot of another jump, the control flow becomes hard to reason about. During the FPGA core implementation, protection delay slot interactions were consistently the most difficult bugs to track down.。heLLoword翻译官方下载对此有专业解读
