* batman-adv: Make bat_priv->primary_if an rcu protected pointerMarek Lindner2011-05-011-4/+13
| | | | | | | | | | | The rcu protected macros rcu_dereference() and rcu_assign_pointer() for the bat_priv->primary_if need to be used, as well as spin/rcu locking. Otherwise we might end up using a primary_if pointer pointing to already freed memory. Signed-off-by: Marek Lindner <lindner_marek@yahoo.de> Signed-off-by: Sven Eckelmann <sven@narfation.org>
* batman-adv: Move definition of atomic_dec_not_zero() into main.hAntonio Quartulli2011-05-011-1/+0
| | | | | | | | atomic_dec_not_zero() is very useful and it is currently defined multiple times. So it is possible to move it in main.h Signed-off-by: Antonio Quartulli <ordex@autistici.org> Signed-off-by: Sven Eckelmann <sven@narfation.org>
* batman-adv: Make orig_node->router an rcu protected pointerLinus Lüssing2011-04-171-7/+12
| | | | | | | | | | | | | | The rcu protected macros rcu_dereference() and rcu_assign_pointer() for the orig_node->router need to be used, as well as spin/rcu locking. Otherwise we might end up using a router pointer pointing to already freed memory. Therefore this commit introduces the safe getter method orig_node_get_router().

* batman-adv: rename global if_list to hardif_listMarek Lindner2011-03-051-2/+2
| | | | | | | | Batman-adv works with "hard interfaces" as well as "soft interfaces". The new name should better make clear which kind of interfaces this list stores. Signed-off-by: Marek Lindner <lindner_marek@yahoo.de>
* batman-adv: separate ethernet comparing calls from hash functionsMarek Lindner2011-03-051-1/+1
| | | | | | | Note: The function compare_ether_addr() provided by the Linux kernel requires aligned memory. Signed-off-by: Marek Lindner <lindner_marek@yahoo.de>
* batman-adv: Remove duplicate types.h inclusionsLinus Lüssing2011-02-111-1/+0
| | | | | | | | | types.h is included by main.h, which is included at the beginning of any other c-file anyway. Therefore this commit removes those duplicate inclussions. Signed-off-by: Linus Lüssing <linus.luessing@ascom.ch> Signed-off-by: Sven Eckelmann <sven@narfation.org>

* net: Add batman-adv meshing protocolSven Eckelmann2010-12-161-0/+585
B.A.T.M.A.N. (better approach to mobile ad-hoc networking) is a routing protocol for multi-hop ad-hoc mesh networks. The networks may be wired or wireless.
