Actually there is only one class of event: Gateway event.
A Uevent is sent to the userspace each time the node ADD/DELETE/CHANGE its =
own
batman-adv-GW. Actually, if the batman-adv-GW is co-located with the L3 GW,=
 you
can use this event to understand whether you have or not a default route in=
 the
network (assuming that I correctly understood your scenario).

Uevents support is in the batman-adv code, but as I told you before we only=
 have
GW events right now. But the code is easily extendible for other uevents :)

Then, in the userspace you can use UDEV to handle such uevents and do somet=
hing
you like (e.g. triggeringa bash script, relaunching another daemon, whateve=
r..)
