2014-01-08batman-adv: remove FSF address from GPL disclaimerAntonio Quartulli1-3/+1
As suggested by checkpatch, remove all the references to the FSF address since the kernel already has one reference in its documentation. In this way it is easier to update it in case of future changes. Signed-off-by: Antonio Quartulli <antonio@meshcoding.com> Signed-off-by: Marek Lindner <mareklindner@neomailbox.ch>

2013-01-12batman-adv: use the const qualifier in hash functionsAntonio Quartulli1-1/+1
The data argument in each hash function should carry the "const" qualifier as it is never modified. Signed-off-by: Antonio Quartulli <antonio@open-mesh.com> Signed-off-by: Marek Lindner <lindner_marek@yahoo.de>
2012-11-14batman-adv: don't rely on positions in struct for hashingSimon Wunderlich1-0/+22
The hash functions in the bridge loop avoidance code expects the VLAN vid to be right after the mac address, but this is not guaranteed. Fix this by explicitly hashing over the right fields of the struct.

2012-07-10net: Fix (nearly-)kernel-doc comments for various functionsBen Hutchings1-1/+2
Fix incorrect start markers, wrapped summary lines, missing section breaks, incorrect separators, and some name mismatches. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-07-01batman-adv: Prefix hash struct and typedef with batadv_Sven Eckelmann1-15/+18

2012-06-24batman-adv: Prefix hash static inline functions with batadv_Sven Eckelmann1-9/+10
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 Eckelmann1-13/+11
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 hash non-static functions with batadv_Sven Eckelmann1-3/+3
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.

2012-06-18batman-adv: fix locking in hash_add()Matthias Schiffer1-9/+6
To ensure an entry isn't added twice all comparisons have to be protected by the hash line write spinlock. This doesn't really hurt as the case that it is tried to add an element already present to the hash shouldn't occur very often, so in most cases the lock would have have to be taken anyways.

2012-06-18batman-adv: Initialize lockdep class keys for hashesSven Eckelmann1-0/+4
The hash for claim and backbone hash in the bridge loop avoidance code receive the same key because they are getting initialized by hash_new with the same key. Lockdep will create a backtrace when they are used recursively. This can be avoided by reinitializing the key directly after the hash_new. Signed-off-by: Sven Eckelmann <sven@narfation.org>

2011-11-20batman-adv: fixed hash functions type to uint32_t instead of intAntonio Quartulli1-6/+7
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.

2011-08-22batman-adv: hash_add() has to discriminate on the return valueAntonio Quartulli1-6/+19
hash_add() returns 0 on success while returns -1 either on error and on entry already present. The caller could use such information to select its behaviour. For this reason it is useful that hash_add() returns -1 in case on error and returns 1 in case of entry already present.

2011-05-30batman-adv: Add const type qualifier for pointersSven Eckelmann1-3/+3
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>

2010-12-16net: Add batman-adv meshing protocolSven Eckelmann1-0/+176
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.
