The interface for scripts in /etc/NetworkManager/dispatcher.d/ is in a poor state. IMO there are likle two ways how third party apps interact with NM: either they receive "events" via the dispatcher hooks, or they are a dbus client. I dont know much about the latter, thats why I assume that an app is notified via dbus and get to the "full state" of NM via dbus. I assume such app does not need dispatcher events. For apps/scripts called via the dispatcher interface the event should be a snapshot of the "full state". But instead they just get some "hey, something happend" event with an incomplete chunk of info. Essentially they are forced to make some sense of this incomplete chunk of info and maintain the state on their own. This is cumbersome and the amount of work to get this right is equal to turn them into full dbus apps and grab all the info from there. For short, the even must include the full info. Examples: The remote VPN gateway sometimes drops the connection, or the router reconnects and gets a new public address. As a result openvpn reconnects. The reconnect event does not include the VPN route info, just the IPv4 address data. I'm sure NM still knows the routes, but I have not looked in dbus whats actually in there. The bridge interface does dhcp, and the "up/dhcp4-change/dhcp6-change" events contain the desired info. But because its a bridge there is also the ethN slave. Most of the time its event carries no info. But it happend two times during boot that ethN instead of br0 carried the address info. Since my scripts have to ignore ethN the required info was essentially lost and the system in a wedged state. Please either fix this, or document it clearly in NetworkManager(8) that the environment info for each event may be incomplete.
