The following commit has been merged in the master branch: commit 08adf1512298201a53b88bb0a3d67e0dbbe0ed9b Author: Sven Eckelmann <sven(a)narfation.org> Date: Sat May 12 13:38:47 2012 +0200 batman-adv: Prefix bridge_loop_avoidance non-static functions with batadv_ batman-adv can be compiled as part of the kernel instead of an module. In that case the linker will see all non-static symbols of batman-adv and all other non-static symbols of the kernel. This could lead to symbol collisions. A prefix for the batman-adv symbols that defines their private namespace avoids such a problem.

In that case the linker will see all non-static symbols of batman-adv and all other non-static symbols of the kernel. This could lead to symbol collisions. A prefix for the batman-adv symbols that defines their private namespace avoids such a problem.

The following commit has been merged in the master branch: commit be9aa4c1e0d7124cf976831db098f1e852fdbd14 Author: Marek Lindner <lindner_marek(a)yahoo.de> Date: Mon May 7 04:22:05 2012 +0800 batman-adv: turn tt commit code into routing protocol agnostic API Prior to this patch the translation table code made assumptions about how the routing protocol works and where its buffers are stored (to directly modify them). Each protocol now calls the tt code with the relevant pointers, thereby abstracting the code.
