When >> batman-adv detects a non-mesh client it automatically starts announcing the >> client's mac address in the mesh network to make the mesh aware of the >> client's location. The new protocol extension mainly deals with the optimal >> handling and propagation of these client position packets. Major benefits >> include: Only changes (client arriving or leaving) are propagated in the >> mesh, >> thereby reducing the protocol overhead; traffic redirection when a client >> roams from one mesh node to the next until the mesh network has converged to >> reduce the packet loss while roaming; extensible packet format to construct >> more features on top of it. >> In addition, batman-adv gained support for informing the user space about >> events via uevent (a long-standing feature request). The gateway subsystem is >> the first to make use of it by sending signals when a new gateway has been >> selected / selected gateway has been changed / the selected gateway has been >> removed. Also, when enabled the gateway subsystem will filter out incoming >> DHCP renewal requests if they are not targeted at a high quality gateway to >> force the client to switch to the best available gateway. >> The routing algorithm received a minor tweaking which make it accept delayed >> OGM rebroadcasts to avoid bogus routing under heavy load. A bug hindering the >> correct broadcast of OGM packets if interfaces were added & removed in a >> particular order was fixed. A similar problem affecting the OGM aggregation >> was eliminated too. The many smaller bug fixes and code stability >> improvements >> make this release a well-rounded package. >> >> >> batctl >> ------ >> >> The Makefile received major attention and various cleanups to make packaging >> of batctl easier. tcpdump was updated, so that it can analyze the new tt & >> roaming packets and was extended by a new option to filter all packets except >> the specified types. An additional debug level for all client announcement >> related information was added too. A pair of small bugs was squashed along >> the >> way: bisect did not properly initialize a variable which led to a compile >> time >> warning and a potential memory leak in the bat-hosts parser fixed. >> >> >> Happy routing, >> The B.A.T.M.A.N. team >> >
