With this patch a multicast packet is not always simply flooded anymore, the behaviour for the following cases is changed to reduce unnecessary overhead: If all nodes within the horizon of a certain node have signalized multicast listener announcement capability then an IPv6 multicast packet with a destination of IPv6 link-local scope (excluding ff02::1) coming from the upstream of this node... * ...is dropped if there is no according multicast listener in the translation table, * ...is forwarded via unicast if there is a single node with interested multicast listeners * ...and otherwise still gets flooded.

This attribute can be used to set and read the value and the mask of the skb mark which will be used to classify the source non-mesh client as ISOLATED. In this way a client can be advertised as such and the mark can potentially be restored at the receiving node before delivering the skb. This can be helpful for creating network wide netfilter policies. This sysfs file expects a string of the shape "$mark/$mask". Where $mark has to be a 32-bit number in any base, while $mask must be a 32bit mask expressed in hex base. Only bits in $mark covered by the bitmask are really stored.

AP isolation has to be enabled on one VLAN interface only. This patch moves the AP isolation attribute to the per-vlan interface attribute set, enabling it to have a different value depending on the selected vlan.

Network coding exploits the 802.11 shared medium to allow multiple packets to be sent in a single transmission. In brief, a relay can XOR two packets, and send the coded packet to two destinations. The receivers can decode one of the original packets by XOR'ing the coded packet with the other original packet. This will lead to increased throughput in topologies where two packets cross one relay. In a simple topology with three nodes, it takes four transmissions without network coding to get one packet from Node A to Node B and one from Node B to Node A: 1. Node A ---- p1 ---> Node R Node B 2. Node A Node R <--- p2 ---- Node B 3. Node A <--- p2 ---- Node R Node B 4. Node A Node R ---- p1 ---> Node B With network coding, the relay only needs one transmission, which saves us one slot of valuable airtime: 1. Node A ---- p1 ---> Node R Node B 2. Node A Node R <--- p2 ---- Node B 3. Node A <- p1 x p2 - Node R - p1 x p2 -> Node B The same principle holds for a topology including five nodes. Here the packets from Node A and Node B are overheard by Node C and Node D, respectively. This allows Node R to send a network coded packet to save one transmission: Node A Node B | \ / | | p1 p2 | | \ / | p1 > Node R < p2 | | | / \ | | p1 x p2 p1 x p2 | v / \ v / \ Node C < > Node D More information is available on the open-mesh.org wiki[1]. This patch adds the initial code to support network coding in batman-adv. It sets up a worker thread to do house keeping and adds a sysfs file to enable/disable network coding. The feature is disabled by default, as it requires a wifi-driver with working promiscuous mode, and also because it adds a small delay at each hop.

When having a mixed topology of both very mobile and rather static nodes, you are usually best advised to set the originator interval on all nodes to a level best suited for the most mobile node. However, if most of the nodes are rather static, this can create a lot of undesired overhead as a trade-off then. If setting the interval too low on the static nodes, a mobile node might be chosen as a router for too long, not switching away from it fast enough because of its mobility and the low frequency of ogms of static nodes. Exposing the hop_penalty is especially useful for the stated scenario: A static node can keep the default originator interval, a mobile node can select a quicker one resulting in faster route updates towards this mobile node. Additionally, such a mobile node could select a higher hop penalty (or even set it to 255 to disable acting as a router for other nodes) to make it less desirable, letting other nodes avoid selecting this mobile node as a router.
