Batman-adv 2019.2 released

Added by Sven Eckelmann 4 days 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 disabled 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.

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:

Batman-adv 2019.1 released

Added by Sven Eckelmann about 2 months ago

Mar 28th, 2019. Today the B.A.T.M.A.N. team publishes the March 2019 update to batman-adv, batctl and alfred! The distributed hash table now parses DHCP packets to speed up the learning process of new IPv4 addresses. This should reduce the number of required ARP packets when a client just received a new IP address and then wants to start to transfer data via this router. Also batman-adv and batctl were modified to exchange configuration settings via generic netlink instead of sysfs. As usual, this release also contains various bugfixes and code cleanups.

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:

Batman-adv 2019.0 released

Added by Sven Eckelmann 4 months ago

Feb 1th, 2019. Today the B.A.T.M.A.N. team publishes the February 2019 update to batman-adv, batctl and alfred! This release decouples the tracing functionality from the (deprecated) debugfs functionality. Most of the netlink functionality now also reports inconsistency problems during the dumping of larger number of entries. As usual, this release also contains various bugfixes and code cleanups.

Batman-adv 2018.4 released

Added by Sven Eckelmann 6 months ago

Nov 14th, 2018. Today the B.A.T.M.A.N. team publishes the November 2018 update to batman-adv, batctl and alfred! This release contains mostly code refactorization in batctl to ease more netlink development in the future. Alfred's IPv4 implementation was polished to better handle missing MAC addresses in the ARP neighbor table. The batman-adv kernel modules now yields better results for TX throughput tests and allows to receive its debug messages via the Linux kernel's tracepoint infrastructure. Accessing the debugfs files will now create warning messages that a different method of retrieving the information should be used. As usual, this release also contains various bugfixes and code cleanups.

Batman-adv 2018.2 released

Added by Sven Eckelmann 10 months ago

Jul 17th, 2018. Today the B.A.T.M.A.N. team publishes the July 2018 update to batman-adv, batctl and alfred! This release drops the support for Linux versions before v3.16 (oldest non-EOL Linux kernel). This makes it possible again to build the kernel in-source without the extra "build/" directory. debugfs is no longer enabled in the standard build configuration but B.A.T.M.A.N. V will be build by default. The later was also modified to no longer accept the ethtool specific link speeds to virtual interfaces - a requirement in the future for the tpmeter based link speed detection of VPN links. The multicast optimization is now more robust and will no longer disable itself when a node without the multicast optimization feature is detected. Also several bugfixes and code cleanups are included in this version.

The B.A.T.M.A.N. project endorses "Mesh is in the air"

Added by Simon Wunderlich about 1 year ago

The B.A.T.M.A.N. project endorses "Mesh is in the air" - this year mesh up of the "Wireless Battle of the Mesh" and "Wireless Community Weekend".

We keep the approach to test the performance of different routing protocols for ad-hoc networks and combine it with the celebration of the 15th anniversary of the yearly Freifunk community get together. The mix becomes a global gathering of wifi tech experts, mesh developers and community networkers that join the event to hack, test, discuss, explain, learn and barbecue at c-base, Berlins famous hack-space-station.

If you are a mesh networking enthusiast, community activist, have an interest in wifi or dynamic routing protocols, you can't miss this event! So check out our continuously updated information about the event at https://www.wireless-meshup.org

The battlemesh is free of charge and open for all, every year we strive to keep participation costs low by negotiating deals for accommodation and food.

This year the event will take place from Monday 7th to Sunday 13th of May, 2018 in Berlin, Germany. The event is locally organized by Freifunk, Germany's community wireless network.

The B.A.T.M.A.N. project endorses and supports the Battle of the Mesh v11 because of the efforts made by its community to advance the field of wireless mesh networking and foster the development of grassroots community networks.

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 organizing the event
  • help setting up the testbed for protocol testing
  • will organize workshops to discuss integration and new features with other communities
  • test our new algorithm B.A.T.M.A.N. V

Many other communities endorse and support the Wireless Battle of The Mesh v11, an up to date list of the endorsers of the Battlemesh 11 can be found at the shared Wireless Mesh-up website.

If you are interested in coming join the event's Mailing List to stay up to date with the latest news.

Batman-adv 2018.0 released

Feb 27th, 2018. Today the B.A.T.M.A.N. team publishes the February 2018 update to batman-adv, batctl and alfred! This release contains mostly bugfixes, code cleanups and documentation updates.

The in-tree version also got support for unicast batman-adv packets in the flow dissector. This can be used to spread the receive processing to different CPU cores with the help of RPS. Users of the out-of-tree module are advised to manually add the patchset to their target systems kernel.
