Batman-adv 2017.3 released

Added by Sven Eckelmann over 7 years ago

Sep 28th, 2017. Today the B.A.T.M.A.N. team publishes the September 2017 update to batman-adv, batctl and alfred! A long standing problem in batman-adv was fixed that could lead to an excessive number of TT management packets when devices disagree about the enabled flags of a device in the translation table. The memory usage of alfred was reduced slightly when it is used with --update-command and receives a lot of updates. Also minor bugfixes and code cleanups are included in this version.

Batman-adv 2017.2 released

Added by Sven Eckelmann over 7 years ago

July 28th, 2017. Today the B.A.T.M.A.N. team publishes the July 2017 update to batman-adv, batctl and alfred! This release introduces various improvements in alfred's primary server selection code. It will reduce the CPU load on meshes with many primary servers by rating multiple servers at once instead of each server separately. batman-adv is now trying harder to avoid the special bridge loop avoidance mac addresses in its translation table. Also minor bugfixes and code cleanups are included in this version.

Batman-adv 2017.1 released

Added by Sven Eckelmann almost 8 years ago

May 23th, 2017. Today the B.A.T.M.A.N. team publishes the May 2017 update to batman-adv, batctl and alfred! This release introduces some improvements for various corner cases of bridge loop avoidance. They especially avoid duplicated packets on an ethernet backbone when DAT is enabled. The maximum fragment size was reduced to the minimum allowed MTU for IPv6 to reduce the risk that an intermediate link cannot transport a fragment and has to drop it. Also minor bugfixes and code cleanups are included in this version.

Batman-adv 2017.0.1 released

Added by Sven Eckelmann about 8 years ago

Mar 7th, 2017. Today the B.A.T.M.A.N. team publishes a bugfix release for the 2017.0 version of batman-adv! An API breaking change was integrated quite late in the Linux 4.11 merge window. This change broke the compilation of BATMAN_V against this version and required a change in the compatibility code of batman-adv. Additionally, a minor fix for the initialization of the gateway selection class was integrated which solves a problem when BATMAN_V is compiled in but BATMAN_IV is enabled. Also the change to generate equally sized fragments was backported from master to avoid a fragment padding problem identified by Martin Weinelt and Matthias Schiffer.

Batman-adv 2017.0 released

Added by Sven Eckelmann about 8 years ago

Feb 28th, 2017. Today the B.A.T.M.A.N. team publishes the February 2017 update to batman-adv, batctl and alfred! This release reduces the number of cases in which batctl depends on running with full root user privileges. Bridge loop avoidance addresses are removed from the translation table to lower its memory usage. The batman-adv compatibility code was optimized to better work with old kernel versions and to build B.A.T.M.A.N. V (without wifi throughput detection) on pre-3.16 kernels. alfred gained an experimental mode to support data synchronization over IPv4 instead of IPv6. Also several bugfixes and code cleanups are included in this version.

Batman-adv 2016.5 released

Added by Sven Eckelmann over 8 years ago

Dec 15th, 2016. Today the B.A.T.M.A.N. team publishes the December 2016 update to batman-adv, batctl and alfred! This release improves the support of systems without debugfs and starts to replace the use of the sysfs files for interface manipulation with rtnetlink. batman-adv can automatically detect some setups which don't require (re)broadcasts on specific interfaces. The support of the multicast optimization under B.A.T.M.A.N. V was improved and the throughput detection now works for VLANs on top of WiFi interfaces. Also several bugfixes, code cleanups and code documentation updates are included in this version.

Batman-adv 2016.4 released

Added by Sven Eckelmann over 8 years ago

Oct 27th, 2016. Today the B.A.T.M.A.N. team publishes the October 2016 update to batman-adv, batctl and alfred! This release enhanced the netlink support and now can replace most of the data currently available via debugfs. batman-adv can therefore be used in multiple network namespaces without collision in debugfs. The size of the translation table was optimized and the gateway selection algorithm for B.A.T.M.A.N. V was integrated. Also several bugfixes, code cleanups and code documentation updates are included in this version.

Batman-adv 2016.3 released

Added by Sven Eckelmann over 8 years ago

Sep 1st, 2016. Today the B.A.T.M.A.N. team publishes the September 2016 update to batman-adv, batctl and alfred! This release contains the multicast optimization support for bridged setups and frame priority support for fragmented packets. The initial set of patches to implement netlink support for batman-adv were integrated. As the first step, it is used to interact with the new kernel throughput benchmark code. Future releases will utilize netlink to replace the current debugfs tables in a more memory efficient way. Also several bugfixes, code cleanups and code documentation updates are included in this version.

As from this release, we will report the summaries from our Changelog for each component instead of a full text.

Batman-adv 2016.2 released

Added by Sven Eckelmann almost 9 years ago

June 09th, 2016. Today the B.A.T.M.A.N. team publishes the June 2016 update to batman-adv, batctl and alfred! This release contains the initial patches to get network namespace support for batman-adv. Also several bugfixes, code cleanups and code documentation updates are included in this version.

Thanks to all people sending in patches:

and to all those that supported us with good advice or rigorous testing:

batman-adv

  • support latest kernels (3.2 - 4.7)
  • initial, limited support for network namespaces
  • kernel doc updates and coding style cleanups
  • cleanup of legacy kernel compat code
  • support for detection and reporting of complex bridge loops
  • bugs squashed:
    • fix some TT issues: double free for full table request structs (created problems on multi-core systems) and a double put of VLAN objects
    • fix various B.A.T.M.A.N. V issues: fix mac address after address change, ELP orig address on secondary interfaces, null pointer dereference in metric comparison, refcount issues, ...
    • fix skb deref after transmission
    • avoid duplicate neigh_node additions
    • replace WARN with rate limited output on non-existing VLAN
    • fix ICMP RR ethernet header access after skb_linearize
    • fix memleak of untagged vlan when removing interface via rtnl-link
    • fix build against Debian Stretch kernels

batctl

batctl's tcpdump component was enriched with an OGM2 and ELP parser to be able to print relevant B.A.T.M.A.N. V information. Also the new "loopdetect" type of bridge loop avoidance ARP packets is now recognized by the tcpdump component.

alfred

alfred now automatically mounts the debugfs before it reduces its capabilities. This avoids problems when it has to query the state of batman-adv via debugfs.
