passt

Plug A Simple Socket Transport

passt implements a thin layer between guest and host, that only implements what's strictly needed to pretend processes are running locally. The TCP adaptation doesn't keep per-connection packet buffers, and reflects observed sending windows and acknowledgements between the two sides. This TCP adaptation is needed as passt runs without the CAP_NET_RAW capability: it can't create raw IP sockets on the pod, and therefore needs to map packets at Layer-2 to Layer-4 sockets offered by the host kernel.

Also provides pasta, which similarly to slirp4netns, provides networking to containers by creating a tap interface available to processes in the namespace, and mapping network traffic outside the namespace using native Layer-4 sockets.
