📄 Description

I suggest netfilter to be affected by restricted-network because it is a traditionally-privileged interface to the kernel, and the security impact of letting untrusted users run their own netfilter scripts (even on their own network namespace) is non-obvious.

Is that OK, or should I introduce a separate config flag for this?
