landjail is Agent Firewall's alternative jail type that uses Landlock V4 for
network isolation.

## Overview [#overview]

Agent Firewall uses Landlock V4 to enforce network restrictions:

* All `bind` syscalls are forbidden
* All `connect` syscalls are forbidden except to the port that is used by http
  proxy

This provides network isolation without requiring network namespace capabilities
or special Docker permissions.
