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>

Remove the existing fragmentation code before adding the new version and delete unicast.{h,c}. batadv_unicast_send_skb() is moved to send.c and renamed to batadv_send_skb_unicast(). fragmentation entry in sysfs (bat_priv->fragmentation) is kept for use in the new fragmentation code. BATADV_UNICAST_FRAG packet type is renamed to BATADV_FRAG for use in the new fragmentation code.

Reordering the packet type numbers allows us to handle unicast packets in a general way - even if we don't know the specific packet type, we can still forward it.

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>

Before adding forward-skbs to the coding buffer, the buffer is searched for a potential coding opportunity. If one is found, the two packets are network coded and transmitted right away. If not, the forward-skb is added to the buffer. Network coded packets are transmitted with information about the two receivers and the two coded packets. The first receiver is given by the MAC header, while the second is given in the payload/bat-header. The second receiver uses promiscuous mode to receive the packet and check the second destination.

All packet headers in front of an ethernet header have to be completely divisible by 2 but not by 4 to make the payload after the ethernet header again 4 bytes boundary aligned. A packing of 2 is necessary to avoid extra padding at the end of the struct caused by a structure member which is larger than two bytes. Otherwise the structure would not fulfill the previously mentioned rule to avoid the misalignment of the payload after the ethernet header. It may also lead to leakage of information when the padding it not initialized before sending.

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.

Headers which are already perfectly aligned and create a 4 byte boundary non-ethernet header payload can have the __packed attribute removed. The __packed attribute doesn't change the appeareance of the packet for these headers because no extra padding is necessary to align the data members. The compiler will also create slightly faster code for loads of multi-byte members.

With the current TT mechanism a new client joining the network is not immediately able to communicate with other hosts because its MAC address has not been announced yet. This situation holds until the first OGM containing its joining event will be spread over the mesh network. This behaviour can be acceptable in networks where the originator interval is a small value (e.g. 1sec) but if that value is set to an higher time (e.g. 5secs) the client could suffer from several malfunctions like DHCP client timeouts, etc. This patch adds an early detection mechanism that makes nodes in the network able to recognise "not yet announced clients" by means of the broadcast packets they emitted on connection (e.g. ARP or DHCP request). The added client will then be confirmed upon receiving the OGM claiming it or purged if such OGM is not received within a fixed amount of time. Signed-off-by: NAntonio Quartulli <ordex@autistici.org>

batman-adv would forward OGMs from non-besthops while replacing the the TQ and TTL values with the values from the best hop. In certain corner cases this leads to a temporary routing loop. This patch changes this behavior: Only packets from best next hops are forwarded - TQ and TTL values won't be replaced anymore. However, the protocol needs to rebroadcast OGMs from single hop neighbors regardless of whether or not they are the best hop. To handle this case a new flag is introduced to alert neighboring nodes about the forwarded OGM that is not from my best next hop. It is to be discarded by all nodes except for the one originating the OGM.
