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

Added by Annika Wickert about 1 month 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 3 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.

As the kernel module always depends on the Linux kernel it is compiled against, it does not make sense to provide binaries on our website. As usual, you will find the signed tarballs in our download section:

Added by Sven Eckelmann 7 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 10 months 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.

Batman-adv 2020.0 released

Added by Sven Eckelmann about 1 year ago

Mar 04th, 2020. Today the B.A.T.M.A.N. team publishes the March 2020 update to batman-adv, batctl and alfred! This release disables the (deprecated) sysfs support by default. The next milestone in this process is the removal of debugfs and sysfs support next year. The B.A.T.M.A.N. V code can now use the PHY transmission rates as another (fallback) source to calculate the expected throughput to specific neighbors. The alfred gps daemon gained support for the gpsd API 9 (libgps >= 3.20). Also several bugfixes and code cleanups are included in this version.

Batman-adv 2019.3 released

Added by Sven Eckelmann almost 2 years ago

Aug 1th, 2019. Today the B.A.T.M.A.N. team publishes the August 2019 update to batman-adv, batctl and alfred! The multicast optimization got support for group-aware optimizations for multicast addresses of scope greater than link-local. batctl was adjusted to handle such information and packets in various subcommands. Also support for hardif (aka. slave/lower interface) specific settings was implemented. This required a change in how meshif and vlans are specified for subcommands. Instead of using "-m" for both meshif and vlans (and now hardifs), they were splitted into special subcommand prefixes:

  • meshif <netdev>
  • vlan <vdev>
  • meshif <netdev> vid <vid>
  • hardif <netdev>

To start a ping on bat2, following command should be used:

$ batctl meshif bat2 ping 02:ba:de:af:fe:01

As usual, this release also contains various bugfixes and code cleanups.
