Batman-adv 2021.3 released

Added by Sven Eckelmann 8 days ago

Sep 14th, 2021. Today the B.A.T.M.A.N. team publishes the September 2021 update to batman-adv! The broadcast queuing changes from 2021.2 were now utilized to reduce the packet copy overhead when sending broadcast packets. Also several code cleanups are included in this version.

Batman-adv 2021.2 released

Added by Sven Eckelmann about 1 month ago

Aug 20th, 2021. Today the B.A.T.M.A.N. team publishes the August 2021 update to batman-adv, batctl and alfred! The multicast support in batman-adv can now utilize the Multicast Router Discovery of the Linux bridge to detect IPv4/IPv6 multicast listeners and routers. The broadcast packet handling was also redesigned to reduce the latency and to prepare the necessary infrastructure for interfaces specific handling. Also several bugfixes and code cleanups are included in this version.

IRC channel moved to irc.hackint.org #batadv

Added by Sven Eckelmann 3 months ago

Due to recent developments around the Freenode.org IRC network, the opinions about the usage of this service shifted dramatically.

A small poll in the IRC channel at the end of last week showed that most (actively participating) users wanted to leave freenode and the network with the most positive votes was hackint.org. The new home at ircs://irc.hackint.org/batadv was prepared on Sunday. You can find also other interesting channels in the neighborhood. #freifunk (including many communities), #gluon, #dn42, various CCC channels and many more.

We hope to see you soon in the new channel at ircs://irc.hackint.org/batadv

Batman-adv 2021.1 released

Added by Sven Eckelmann 4 months ago

May 18th, 2021. Today the B.A.T.M.A.N. team publishes the May 2021 update to batman-adv, batctl and alfred! batctl gained the support for "*_json" commands which make it possible to query the batman-adv kernel module over generic netlink and receive the answer as JSON. The alfred server was modified to start the server even when batman-adv or interface(s) are not yet available. A special parameter "--force" must be provided to enable this behavior. Also several bugfixes and code cleanups are included in this version.

systemd v248 brings support for B.A.T.M.A.N. Advanced

Added by Annika Wickert 6 months ago

With the release of systemd v248, systemd-networkd now supports creation and management of B.A.T.M.A.N. Advanced interfaces.

The minimum required version of batman-adv to work with systemd-networkd is 2021.0.

An example .netdev file looks like the following:

[NetDev]
Name=bat0
Kind=batadv

[BatmanAdvanced]
GatewayMode=server
RoutingAlgorithm=batman-v
OriginatorIntervalSec=5

Thanks

For all the reviews and advices The initial idea

Batman-adv 2021.0 released

Added by Sven Eckelmann 8 months ago

Jan 28th, 2021. Today the B.A.T.M.A.N. team publishes the January 2021 update to batman-adv, batctl and alfred! The deprecated support for batman-adv's sysfs and debugfs files was removed from all components. batctl and batman-adv now also allow the selection of the routing algorithm during the interface creation. This can be used to avoid the undefined behavior when multiple processes trying to create interfaces with different routing algorithms. Also several bugfixes and code cleanups are included in this version.

Added by Sven Eckelmann 11 months ago

Oct 27th, 2020. Today the B.A.T.M.A.N. team publishes the October 2020 update to batman-adv and batctl! The bridge loop avoidance and translation table code received several fixes for bugs in connection with the multicast optimization. Which would otherwise potentially cause packet loss or even routing loops. Also several code cleanups are included in this version.

Batman-adv 2020.2 released

Added by Sven Eckelmann about 1 year ago

Jul 6th, 2020. Today the B.A.T.M.A.N. team publishes the July 2020 update to batman-adv, batctl and alfred! This release drops the support for the end-of-life Linux kernel versions (<4.3). The B.A.T.M.A.N. V throughput detection for ethernet devices without auto-negotiation was enabled again to support more configurations out of the box. Most users will still require a manual setting via the throughput_override for such devices. The automatic removal of (empty) batadv mesh interfaces during a batctl meshif bat0 interface del .... was dropped. An explicit batctl meshif bat0 interface destroy is now required to remove the batadv interface. Also several bugfixes and code cleanups are included in this version.
