2012-11-07batman-adv: Distributed ARP Table - create DHT helper functionsAntonio Quartulli1-0/+4
Add all the relevant functions in order to manage a Distributed Hash Table over the B.A.T.M.A.N.-adv network. It will later be used to store several ARP entries and implement DAT (Distributed ARP Table) Signed-off-by: Antonio Quartulli <ordex@autistici.org>
2012-11-07batman-adv: add UNICAST_4ADDR packet typeAntonio Quartulli1-1/+31
The current unicast packet type does not contain the orig source address. This patches add a new unicast packet (called UNICAST_4ADDR) which provides two new fields: the originator source address and the subtype (the type of the data contained in the packet payload). The former is useful to identify the node which injected the packet into the network and the latter is useful to avoid creating new unicast packet types in the future: a macro defining a new subtype will be enough.

2012-06-24batman-adv: Prefix unicast 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>
2012-06-21batman-adv: Reformat multiline comments to consistent styleSven Eckelmann1-3/+1
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>
2012-06-21batman-adv: Prefix unicast non-static functions with batadv_Sven Eckelmann1-6/+7
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.

2011-05-30batman-adv: Calculate sizeof using variable insead of typesSven Eckelmann1-1/+1
Documentation/CodingStyle recommends to use the form p = kmalloc(sizeof(*p), ...); to calculate the size of a struct and not the version where the struct name is spelled out to prevent bugs when the type of p changes. This also seems appropriate for manipulation of buffers when they are directly associated with p. Signed-off-by: Sven Eckelmann <sven@narfation.org>
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>

2011-01-31batman-adv: Calculate correct size for merged packetsSven Eckelmann1-0/+23
The routing algorithm must be able to decide if a fragment can be merged with the missing part and still be passed to a forwarding interface. The fragments can only differ by one byte in case that the original payload had an uneven length. In that situation the sender has to inform all possible receivers that the tail is one byte longer using the flag UNI_FRAG_LARGETAIL. The combination of UNI_FRAG_LARGETAIL and UNI_FRAG_HEAD flag makes it possible to calculate the correct length for even and uneven sized payloads. The original formula missed to add the unicast header at all and forgot to remove the fragment header of the second fragment. This made the results highly unreliable and only useful for machines with large differences between the configured MTUs.

2010-12-17net: Add batman-adv meshing protocolSven Eckelmann1-0/+35
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. See http://www.open-mesh.org/ for more information and user space tools. Signed-off-by: Sven Eckelmann <sven@narfation.org> Signed-off-by: David S. Miller <davem@davemloft.net>
