[B.A.T.M.A.N.] batman-adv 2011.4.0 released

[Marek Lindner <lindner_marek@yahoo.de>]

The B.A.T.M.A.N. team is proud to announce its final milestone in 2011, 
2011.4.0, concentrating on the stabilization & bug fixing of the recent 
protocol changes and adding some smaller features . As the kernel module 
always depends on the Linux kernel it was 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: 

http://downloads.open-mesh.org/batman/releases/batman-adv-2011.4.0/ 

as well as prepackaged binaries in your distribution.

batman-adv
----------

Above all, the 2011.4.0 milestone centers around polishing the protocol 
changes introduced with the previous release. Non-mesh clients connected via a 
wireless interface are marked as such. This information is then propagated in 
the mesh on top of the new non-mesh client infrastructure and can be used to 
prevent mesh wide wireless client to wireless client communication (on 
standard WiFi AccessPoints this feature is known as 'AP isolation'). The non-
mesh client status flags (new/delete/purge/roaming/wireless) are exported to 
user space as part of the translation table output to allow following a 
client's status closely.
The coming releases will be escorted by a stepwise inclusion of an improved 
version of our routing algorithm. It will be possible to switch between the 
current protocol and the new protocol at runtime in order to make testing as 
easy as possible. This first stage prepared the existing routing algorithm 
code for the upcoming feature for switching routing protocols. No changes to 
the routing code behavior have been included.
A couple of translation table bugs have been squashed: memory leaks in the 
translation table, wrong initialization of ethernet addresses of translation 
table entries and a kernel crash on module unload. Numerous spelling mistakes 
in the source code comments were corrected.


batctl
------

batctl received an option to turn on/off the aforementioned mesh wide AP 
isolation. When called with '-v' batctl will not only print its own version 
but also the batman-adv kernel module version (requires the module to be 
loaded). The log level section was rewritten, so that it now expects human 
readable log level definitions instead of digits and bitmasks. Also fixed was 
the mangled tcpdump output of the CRC value in translation table exchange 
packets.


Happy routing, 
The B.A.T.M.A.N. team
