Open-Mesh: Batman-adv 2020.4 released

Added by Sven Eckelmann about 1 month 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.

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:

Open-Mesh: Batman-adv 2020.2 released

Added by Sven Eckelmann 5 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.

Open-Mesh: Batman-adv 2020.0 released

Added by Sven Eckelmann 9 months 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.

Oct 25th, 2019. Today the B.A.T.M.A.N. team publishes the October 2019 update to batman-adv, batctl and alfred! The B.A.T.M.A.N. V implementation can now aggregate OGM2 messages into single messages before sending them out. As usual, this release also contains various bugfixes and code cleanups.

Open-Mesh: Batman-adv 2019.3 released

Added by Sven Eckelmann over 1 year 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.

Open-Mesh: The B.A.T.M.A.N. project endorses Wireless Battle Mesh v12

Added by Simon Wunderlich over 1 year ago

The event aims to bring together people from across the globe who are interested in community networks, including wireless mesh network technologies, fiber infrastructure, Do-It-Yourself Internet Access Providers, and more generally how to create and maintain a thriving community of people involved in building their own networks.

We envision 7 days full of expert presentations, practical workshops, late-night hacking sessions, and fruitful discussions: whether you are a mesh networking enthusiast, community networking activist, protocol developer, or have an interest in networking in general, come and join the event!

Thanks to generous sponsors, the Battlemesh is free of charge and open for all, and every year the local organization team strives to keep participation costs low by negotiating deals for accommodation and food.

This year, the event will take place from Monday 8th to Sunday 14th of July, 2019 in Saint-Denis (Paris), France. The event is locally organized.
Check out continuously updated information about the event at https://www.battlemesh.org/BattleMeshV12

The B.A.T.M.A.N. project endorses and supports “Wireless Battle of the Mesh – Building Community Networks for Fun and Non-Profit” not only for the efforts made by its community to advance the field of wireless mesh networking and foster the development of grass-roots community networks, but for their contribution to digital freedom rights movement, empowerment of peoples tech/net/media competency and a free and open civil society.

The B.A.T.M.A.N. project will support the event by:

  • help to promote the event
  • numerous members of the B.A.T.M.A.N. community have already confirmed their attendance
  • help setting up the testbed for protocol testing
  • test our new algorithm B.A.T.M.A.N. V

Open-Mesh: Batman-adv 2019.2 released

Added by Sven Eckelmann over 1 year ago

May 23th, 2019. Today the B.A.T.M.A.N. team publishes the May 2019 update to batman-adv, batctl and alfred! To improve the overhead in networks with multicast listeners, adjustments for the multicast optimization were implemented which enable multicast-to-unicast conversion. batman-adv can now update the DAT entry timeouts on incoming ARP replies to reduce the broadcast overhead even further. The sysfs integration in batman-adv is now optional and can be turned off during the compilation. A system without the sysfs support also requires additional changes in batctl which are shipped now as part of this release. Also the deprecated debugfs log support in batctl was dropped together with the support of MAC-to-originator translation via debugfs. As usual, this release also contains various bugfixes and code cleanups.
