B.A.T.M.A.N. V. Its implementation started quite some years ago, but due to the big changes being introduced it took a while to be discussed, designed, worked, re-worked, tested and debugged (well, we're never done with the latest). The entire operation has basically been a team work involving all the core contributors together with other people interested in the project. The new protocol is divided into two main subcomponents, called respectively ELP and OGMv2. The former is in charge of dealing with the neighbour discovery and link quality estimation, while the latter implements the algorithm that spreads the metrics around the network and computes optimal paths. The biggest change introduced with B.A.T.M.A.N. V is the new metric: the protocol won't rely on packet loss anymore, but it will use the estimated throughput extracted directly from the wifi driver (when available) by querying cfg80211. Batman-adv will also send some unicast probing packets when an interface is not used for payload traffic to make sure that such values are current. The new protocol can be compiled-in or not like other features we have and when selected will pull in CFG80211 as dependency for the reason described above. Thanks to the big work brought up in the past by Marek Lindner, batman-adv can easily deal several protocol implementations, therefore compiling in this new version does not exclude the older. This means that the user is offered the option to choose the protocol when creating the mesh interface (default is the old one to keep backward compatibility). Along with the protocol there are some sysfs knobs that are introduced to fine tune some of its behaviours, but users are recommended to keep the default values unless they know what they are doing. The last patch is about advertising our own patchwork platform (thanks to Sven Eckelmann for having set that up!) in the MAINTAINERS file. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJW1AvOAAoJENpFlCjNi1MRKxsP/1BR8Wh3MrtNhX7MMe7PnZEQ p00kArkjtnZCbBVFbG3JduqYaOPnGyzCLgBgF3DnOxx8gAGUEu6fu4AQNNr9jiUM 4lPnPbe5NuvjzQW27fJDZMuy4Y1FLaJ5DeoYjDH48/YDNS38nzlPPtNwg0pJA2TG C22dM6CX9kzxiy5RETmjgIjK2fgIybudWtCv7BGZxNyiqMaq+bYD+ZJJ6/wbj/FV uKbWB28puJZ3U3qTJ6ygbhAq8moeubp/nbZeh2RGkhpmnS7LKgdLWyPxJLAEza7Z jbdhyAE2xDYaU2xxVdOH9GecSYeUlQ+mrBdEblo2cfKMgShwZBrNjQxCaJIHN3G9 ta44yUpjGFl6/HIQnzfNZD4bTRNnb/DeRTG5qWxdrGAbxZESsMPf1Ph/hZ+KvSZ5 7eSZPmVGRYl8hJaLc25bG8pCOLQRsx/54hXNqYRqmImiPQi4IRvKUQkEDXBpHrT+ EwChfIQvCJSzZQAljrhYP/ytg/CiZxNKgW1u8cJRlHRs3jbBxJUJ67gvf2yWdQdj Luc76uLA1++8QLqhny6AtLeRrr7mYDFnJuNjkwbqWFSyBK6r/lKS1L3ereTfeVIM 5VWMuEDlbWuPscufDJ6WDgWwTqypybjvYbnDlQV7xHap7OegyS/ukQVz2W5lXvS1 gGERfC8WeW1JnFb5TSAY =qd6p -----END PGP SIGNATURE----- Merge tag 'batman-adv-for-davem' of git://git.open-mesh.org/linux-merge Antonio Quartulli says: ==================== batman-adv 20160229 this is our (hopefully) latest batch of patches intended for net-next. With this patchset we finally introduce B.A.T.M.A.N. V: the latest version of our routing protocol. Technical documentation describing the protocol in more detail can be found in our wiki[1][2][3][4]. For what concerns this pull request, you can find the high level description right below.
