Hi,
Jiri Pirko called the batman-adv configuration interface a while back "a huge mistake" [1] and suggested genl as alternative. The first reimplementation [2] (based on the team/devlink design) was rejected. This second implementation is now using a nl80211-like design. The objects which can now be modified/queried are:
* mesh/soft-interface (BATADV_CMD_GET_MESH/BATADV_CMD_SET_MESH) * slave/hard-interface (BATADV_CMD_GET_HARDIF/BATADV_CMD_SET_HARDIF) * vlan (BATADV_CMD_GET_VLAN/BATADV_CMD_SET_VLAN)
Such a set messages automatically triggers a *_SET_* "reply" via the config multicast group. The same behavior was also added to the sysfs interface.
Luckily, Jiri Pirko told us that he will have a look at patches. I would also like to ask the other developers to check whether their configuration values are represented correctly. And please also check whether the current implementation might collide with some other features which you might have in your pipeline.
v2: * rewrite everything in a more nl80211-like message/attribute format.
Kind regards, Sven
