Subject: pull request: batman-adv 2013-10-09
Hello David,
this is a set of changes intended for net-next/linux-3.13.
As introduced one year ago (http://article.gmane.org/gmane.org.freifunk.batman/8484)
in the last period we have been busy working on giving our batman-adv
protocol/packet-format all those means to get stable and avoid incompatibilities
in the near future (this is also why we did not send many changes for
linux-3.12..).
With this patchset we are finally switching to a new compatibility version and
within this development cycle I will send you all those changes aimed to
introduce all the needed mechanism to avoid any further compatibility breakage.
First of all, in this batch you have the new TVLV code (Type Version Value
Length) which is the first very important milestone towards our goal[1].
With this mechanism we will be able to improve/change the packet contents layout
(used by the various features) without breaking compatibility with older
protocol versions anymore.
The development of this new component has been started by Spyros Gasteratos
during his Google Summer of Code 2012 and then adjusted, finished and submitted
by Marek Lindner.
Together with it, you have a set of improvements that we are allowed to apply
thanks to the switching to the new compat version.
These changes are:
- adapt the existing features to make them use the new TVLV mechanism
- move from CRC16 to CRC32c for table correctness check in the TT component
- reorder some of the flags sent over the wire
- remove the __packed attribute from the OGM packet struct.
Moreover, with this patchset we are totally removing our VISualisation component
that is now implemented in userspace.
Please pull let me know of any problem.
Thank you,
Antonio
