[B.A.T.M.A.N.] Changing bat0 mac address
by Gioacchino Mazzurco 22 Apr '11

22 Apr '11

Hi! Is possible to change bat0 mac address? There is some batman-adv specific way or i have to look for how to change mac address on a interface more in general?

[B.A.T.M.A.N.] batman-adv vis_data

Hi! In Pisa we are switching to batman-adv for our mesh, we use the version packaged in openwrt. But it seems that the output of vd is not conform to specification in this page http://www.open-mesh.org/wiki/batman-adv/VisAdv especially the box representing a node is painted only for the node where you call 'batctl vd dot' here you can see what is happening http://eigenlab.org/batman-adv_status.php to simplify visualization i am generating it with 'batctl vd dot -H'

Hi! Here in Pisa we are experiencing a big problem! Nodes doesn't see each other on cable! below is some data from the 2 nodes As you can see nodes receives each other BAT packets but don't see each other as neighbor... also batctl tr can confirm it... what is happening?

Yes, batman-adv provides this functionality. But iirc you cannot add the same real device to more than one bat-interface. So, for example, eth0 can be added to bat0 but then you can't add it to bat1 If you really want to do this I think you can first split eth0 in eth0:1 and eth0:2, as different vlans, and then add them to two different bat-interfaces.

[B.A.T.M.A.N.] batman-adv 2011.1.0 released
by Marek Lindner 20 Apr '11

20 Apr '11

The B.A.T.M.A.N. team is publishing its second 2011 release - 2011.1.0, containing major code changes under the hood to improve performance and scalability plus the usual set of bug fixes. 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-2011.1.0/ as well as prepackaged binaries in your distribution. Thanks ------ Thanks to all people sending in patches: * Jesper Juhl <jj(a)chaosbits.net> * Linus Lüssing <linus.luessing(a)web.de> * Lucas De Marchi <lucas.demarchi(a)profusion.mobi> * Marek Lindner <lindner_marek(a)yahoo.de> * Simon Wunderlich <siwu(a)hrz.tu-chemnitz.de> * Sven Eckelmann <sven(a)narfation.org> * Sylvestre Ledru <sylvestre.ledru(a)scilab.org> batman-adv ---------- The principal objective while working towards this release was to remove the originator hash lock (also known as the batman-adv private "big kernel lock"). It was introduced in the very early stages of the batman-adv development which proved to be a simple and effective way to protect all originator node information from parallel access. As time went on, the module grew and gained more features - most of them making heavy use of the aforementioned originator hash lock as it safeguarded the module's central pool of data. It thereby became a major bottleneck because almost every piece of code had to acquire this very same lock. An extensive effort was necessary to replace the originator hash lock by fine grained locking which only locks the bare minimum of data to improve the module's performance and scalability. Other parts of the code received attention too: After learning about bufferbloat in one of Jim Getty's talks we revisited our own buffering settings and decided to set the txqueuelen to zero. Fragmented packets are now properly linearized upon receipt to avoid a crash if the network card splits the packet into smaller chunks. The fragment numbering became more robust and several spelling mistakes have been corrected. batctl ------ To render batctl more versatile packet dump functionality support for raw WiFi packet decapsulation was added. This allows to keep an eye on your network using interfaces in monitor mode which output packets including all WiFi headers. The bug causing to display an erroneously warning message when changing gateway settings has been squashed. Unused code and the last trace of our subversion integration in the Makefile have been removed. Happy routing, The B.A.T.M.A.N. team

I am not sure if this are hexadecimal > number or what. I would think that you wrote the part which prints out this values. This means that you know which parameters you gave printk and that you should know the conversation specifiers and length modifiers that you used in the format string. But I would guess without having any of these information that you used %x to print these values. Whatever you used as argument - 32 bit (size of single int) of it were printed in unsigned in hexidecimal notation. Maybe you should think about using %lx to print unsigned long ints in hexidecimal notation in case you really used %x. Which brings me to another question: Why to I see 6 numbers in your post and why has the first one 9 nibbles? As said before (and also recommended by Linus): try to write a small c program which uses these values, print the single bits, try to write some test algorithm using these decoded bits and play a little bit around with other test inputs before trying random things inside the kernel. > Again this is the results of printing seq_bits, so far > i have not been able to print real_bits as this cannot even make a > network ping. Could you enlighten me in this case. I cannot understand how pings and printks are related... May I ask how these things are related to your work/studies? It is ok to play around a little bit as small side project/hobby without having the time and knowledge to understand what you are really doing. That is usually a good way to find new interesting topics and maybe to learn something (or blow up a building...). But I would highly recommend to switch the topic in case this is part of your thesis or work. It is not meant as harsh criticism of what you try to do, but it seems that right now you aren't able to efficiently work with it and to gain enough knowledge by yourself to be able to understand simple parts the thing you are working with.
