The following commit has been merged in the master branch: commit c2d0f48a13e53b4747704c9e692f5e765e52041a Author: Sven Eckelmann <sven(a)narfation.org> Date: Wed Nov 30 21:47:09 2016 +0100 batman-adv: Check for alloc errors when preparing TT local data batadv_tt_prepare_tvlv_local_data can fail to allocate the memory for the new TVLV block. The caller is informed about this problem with the returned length of 0. Not checking this value results in an invalid memory access when either tt_data or tt_change is accessed.
