The current condition actually does NOT consider bonding when the interface the packet came in from is the soft interface, which is the opposite of what it should do (and the comment describes). Fix that and slightly simplify the condition.

pskb_may_pull() returns 1 on success and 0 in case of failure, therefore checking for the return value being negative does not make sense at all. This way if the function fails we will probably read beyond the current skb data buffer. Fix this by doing the proper check.

With the new interface alternating, the first hop may send packets in a round robin fashion to it's neighbors because it has multiple valid routes built by the multi interface optimization. This patch enables the feature if bonding is selected. Note that unlike the bonding implemented before, this version is much simpler and may even enable multi path routing to a certain degree.

Instead of handling icmp packets only up to length of icmp_packet_rr, the code should handle any icmp length size. Therefore the length truncating is moved to when the packet is actually sent to userspace (this does not support lengths longer than icmp_packet_rr yet). Longer packets are forwarded without truncating. This patch also cleans up some parts where the icmp header struct could be used instead of other icmp_packet(_rr) structs to make the code more readable.

the icmp and the icmp_rr packets share the same initial fields since they use the same code to be processed and forwarded. Extract the common fields and put them into a separate struct so that future ICMP packets can be easily added without bloating the packet definition. However, keep the seqno field outside of the newly created common header because future ICMP types may require a bigger sequence number space. This change breaks compatibility due to fields reordering in the ICMP headers. Signed-off-by: NAntonio Quartulli <antonio@open-mesh.com> Signed-off-by: NMarek Lindner <lindner_marek@yahoo.de>

The goal is to provide the infrastructure for sending, receiving and parsing information 'containers' while preserving backward compatibility. TVLV (based on the commonly known Type Length Value technique) was chosen as the format for those containers. Even if a node does not know the tvlv type of a certain container it can simply skip the current container and proceed with the next. Past experience has shown features evolve over time, so a 'version' field was added right from the start to allow differentiating between feature variants - hence the name: T(ype) V(ersion) L(ength) V(alue). This patch introduces the basic TVLV infrastructure: * register / unregister tvlv containers to be sent with each OGM (on primary interfaces only) * register / unregister callback handlers to be called upon finding the corresponding tvlv type in a tvlv buffer * unicast tvlv send / receive API calls Signed-off-by: NMarek Lindner <lindner_marek@yahoo.de> Signed-off-by: NSpyros Gasteratos <morfeas3000@gmail.com> Signed-off-by: NAntonio Quartulli <antonio@meshcoding.com>

In the two cases the header size is different, but the mechanism checking the TTVN field was assuming it to be always of the same type (UNICAST), so failing to access the inner Ethernet header in case of UNICAST4ADDR.

To be able to decode a network coded packet, a node must already know one of the two coded packets. This is done by buffering skbs before transmission and buffering packets sniffed with promiscuous mode from other hosts. Packets are kept in a buffer similar to the one with forward-skbs: A hash table, where each entry, which corresponds to a src-dst pair, has a linked list packets.

Two be able to network code two packets, one packet must be buffered until the next is available. This is done in a "coding buffer", which is essentially a hash table with lists of packets. Each entry in the hash table corresponds to a specific src-dst pair, which has a linked list of packets that are buffered. This patch adds skbs to the buffer just before forwarding them. The buffer is traversed every 10 ms, where timed skbs are removed from the buffer and transmitted. To allow experiments with the network coding scheme, the timeout is tunable through a file in debugfs.

I'm not sure why, but the hlist for each entry iterators were conceived list_for_each_entry(pos, head, member) The hlist ones were greedy and wanted an extra parameter: hlist_for_each_entry(tpos, pos, head, member) Why did they need an extra pos parameter? I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually.
