Switch wheel to netdev group in dbus policy In Debian there's a specific dedicated group that is supposed to give permission to manage the network, called netdev. Thus replace the generic, and in debian not very widely used, wheel group in the default policy.
ap: only accept ptk 4/4 after receiving ptk 2/4 When operating as an AP, drop message 4 of the 4-way handshake if the AP has not yet received message 2. Otherwise an attacker can skip message 2 and immediately send message 4 to bypass authentication (the AP would be using an all-zero ptk to verify the authenticity of message 4).
