NetworkManager runs as root and has lots of capabilities. We want to reduce the attach surface by dropping capabilities, but there is a genuine need to do certain things. For example, we currently require dac_override capability, to open the unix socket of ovsdb. Most users wouldn't use OVS, so we should find a way to not require that dac_override capability. The solution is to have a separate, D-Bus activate service (nm-sudo), which has the capability to open and provide the file descriptor. For authentication, we only rely on D-Bus. We watch the name owner of NetworkManager, and only accept requests from that service. We trust D-Bus to get it right a request from that name owner is really coming from NetworkManager. If we couldn't trust that, how could PolicyKit or any authentication via D-Bus work? For testing, the user can set NM_SUDO_NO_AUTH_FOR_TESTING=1. https://bugzilla.redhat.com/show_bug.cgi?id=1921826
