*	batman-adv: Make orig_node->router an rcu protected pointer	Linus Lüssing	2011-04-17	1	-0/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	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: Correct rcu refcounting for orig_node	Marek Lindner	2011-03-05	1	-2/+4
\| \| \| \| \| \| \| \| \| \| \|	It might be possible that 2 threads access the same data in the same rcu grace period. The first thread calls call_rcu() to decrement the refcount and free the data while the second thread increases the refcount to use the data. To avoid this race condition all refcount operations have to be atomic. Reported-by: Sven Eckelmann <sven@narfation.org> Signed-off-by: Marek Lindner <lindner_marek@yahoo.de>

*	batman-adv: protect bonding with rcu locks	Simon Wunderlich	2011-03-05	1	-0/+1
\| \| \| \| \| \| \| \| \| \|	bonding / alternating candidates need to be secured by rcu locks as well. This patch therefore converts the bonding list from a plain pointer list to a rcu securable lists and references the bonding candidates.
