2012-07-01batman-adv: Prefix types structs with batadv_Sven Eckelmann1-16/+19
Reported-by: Martin Hundebøll <martin@hundeboll.net> Signed-off-by: Sven Eckelmann <sven@narfation.org>
2012-07-01batman-adv: Prefix hash struct and typedef with batadv_Sven Eckelmann1-1/+1

2012-06-25batman-adv: Prefix main static inline functions with batadv_Sven Eckelmann1-1/+1
All non-static symbols of batman-adv were prefixed with batadv_ to avoid collisions with other symbols of the kernel. Other symbols of batman-adv should use the same prefix to keep the naming scheme consistent. Signed-off-by: Sven Eckelmann <sven@narfation.org>
2012-06-24batman-adv: Prefix originator static inline functions with batadv_Sven Eckelmann1-4/+4
All non-static symbols of batman-adv were prefixed with batadv_ to avoid collisions with other symbols of the kernel. Other symbols of batman-adv should use the same prefix to keep the naming scheme consistent. Signed-off-by: Sven Eckelmann <sven@narfation.org>
2012-06-20batman-adv: Reformat multiline comments to consistent styleSven Eckelmann1-5/+4
batman-adv doesn't follow the style for multiline comments that David S. Miller prefers. All comments should be reformatted to follow this consistent style to make the code slightly more readable. Signed-off-by: Sven Eckelmann <sven@narfation.org>
2012-06-20batman-adv: Prefix originator non-static functions with batadv_Sven Eckelmann1-10/+11
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.

2011-11-20batman-adv: fixed hash functions type to uint32_t instead of intAntonio Quartulli1-1/+1
There are two reasons for this fix: - the result of choose_orig() and vis_choose() is an index and therefore it can't be negative. Hence it is correct to make the return type unsigned too. - sizeof(int) may not be the same on ALL the architectures. Since we plan to use choose_orig() as DHT hash function, we need to guarantee that, given the same argument, the result is the same. Then it is correct to explicitly express the size of the return type (and the second argument). Since the expected length is currently 4, uint32_t is the most convenient choice.

2011-06-20batman-adv: Move compare_orig to originator.cSven Eckelmann1-8/+0
compare_orig is only used in context of orig_node which is managed inside originator.c. It is not necessary to keep that function inside the header originator.h. Signed-off-by: Sven Eckelmann <sven@narfation.org>
2011-05-30batman-adv: Add const type qualifier for pointersSven Eckelmann1-7/+7
batman-adv uses pointers which are marked as const and should not violate that type qualifier by passing it to functions which force a cast to the non-const version. Signed-off-by: Sven Eckelmann <sven@narfation.org>
2011-04-17batman-adv: Make orig_node->router an rcu protected pointerLinus Lüssing1-0/+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().

2011-03-05batman-adv: Correct rcu refcounting for orig_nodeMarek Lindner1-2/+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>

2011-03-05batman-adv: protect bonding with rcu locksSimon Wunderlich1-0/+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.

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.
