2016-07-04batman-adv: throughput meter implementationAntonio Quartulli
The throughput meter module is a simple, kernel-space replacement for throughtput measurements tool like iperf and netperf. It is intended to approximate TCP behaviour. It is invoked through batctl: the protocol is connection oriented, with cumulative acknowledgment and a dynamic-size sliding window. The test *can* be interrupted by batctl. A receiver side timeout avoids unlimited waitings for sender packets: after one second of inactivity, the receiver abort the ongoing test.

2016-06-30batman-adv: Include frame priority in fragment headerAndrew Lunn
Unfragmented frames which traverse a node have their skb->priority set by looking at the IP ToS byte, or the 802.1p header. However for fragments this is not possible, only one of the fragments will contain the headers. Instead, place the priority into the fragment header and on receiving a fragment, use this information to set the skb->priority for when the fragment is forwarded.

2016-05-10batman-adv: add detection for complex bridge loopsSimon Wunderlich
There are network setups where the current bridge loop avoidance can't detect bridge loops. The minimal setup affected would consist of two LANs and two separate meshes, connected in a ring like that: A...(mesh1)...B | | (LAN1) (LAN2) | | C...(mesh2)...D Since both the meshes and backbones are separate, the bridge loop avoidance has not enough information to detect and avoid the loop in this case. Even if these scenarios can't be fixed easily, these kind of loops can be detected. This patch implements a periodic check (running every 60 seconds for now) which sends a broadcast frame with a random MAC address on each backbone VLAN. If a broadcast frame with the same MAC address is received shortly after on the mesh, we know that there must be a loop and report that incident as well as throw an uevent to let others handle that problem.

2016-02-29batman-adv: OGMv2 - add basic infrastructureAntonio Quartulli
This is the initial implementation of the new OGM protocol (version 2). It has been designed to work on top of the newly added ELP. In the previous version the OGM protocol was used to both measure link qualities and flood the network with the metric information. In this version the protocol is in charge of the latter task only, leaving the former to ELP. This means being able to decouple the interval used by the neighbor discovery from the OGM broadcasting, which revealed to be costly in dense networks and needed to be relaxed so leading to a less responsive routing protocol.

2016-02-29batman-adv: ELP - adding basic infrastructureLinus Luessing
The B.A.T.M.A.N. protocol originally only used a single message type (called OGM) to determine the link qualities to the direct neighbors and spreading these link quality information through the whole mesh. This procedure is summarized on the BATMAN concept page and explained in details in the RFC draft published in 2008. This approach was chosen for its simplicity during the protocol design phase and the implementation. However, it also bears some drawbacks: * Wireless interfaces usually come with some packet loss, therefore a higher broadcast rate is desirable to allow a fast reaction on flaky connections. Other interfaces of the same host might be connected to Ethernet LANs / VPNs / etc which rarely exhibit packet loss would benefit from a lower broadcast rate to reduce overhead. * It generally is more desirable to detect local link quality changes at a faster rate than propagating all these changes through the entire mesh (the far end of the mesh does not need to care about local link quality changes that much). Other optimizations strategies, like reducing overhead, might be possible if OGMs weren't used for all tasks in the mesh at the same time. As a result detecting local link qualities shall be handled by an independent message type, ELP, whereas the OGM message type remains responsible for flooding the mesh with these link quality information and determining the overall path transmit qualities.

2015-06-07batman-adv: Add required includes to all filesSven Eckelmann
The header files could not be build indepdent from each other. This is happened because headers didn't include the files for things they've used. This was problematic because the success of a build depended on the knowledge about the right order of local includes. Also source files were not including everything they've used explicitly. Instead they required that transitive includes are always stable. This is problematic because some transitive includes are not obvious, depend on config settings and may not be stable in the future. The order for include blocks are: * primary headers (main.h and the *.h file of a *.c file) * global linux headers * required local headers * extra forward declarations for pointers in function/struct declarations The only exceptions are linux/bitops.h and linux/if_ether.h in packet.h. This header file is shared with userspace applications like batctl and must therefore build together with userspace applications. The header linux/bitops.h is not part of the uapi headers and linux/if_ether.h conflicts with the musl implementation of netinet/if_ether.h. The maintainers rejected the use of __KERNEL__ preprocessor checks and thus these two headers are only in main.h. All files using packet.h first have to include main.h to work correctly.

2014-03-22batman-adv: Send multicast packets to nodes with a WANT_ALL flagLinus Lüssing
With this patch a node sends IPv4 multicast packets to nodes which have a BATADV_MCAST_WANT_ALL_IPV4 flag set and IPv6 multicast packets to nodes which have a BATADV_MCAST_WANT_ALL_IPV6 flag set, too. Why is this needed? There are scenarios involving bridges where multicast report snooping and multicast TT announcements are not sufficient, which would lead to packet loss for some nodes otherwise: MLDv1 and IGMPv1/IGMPv2 have a suppression mechanism for multicast listener reports. When we have an MLDv1/IGMPv1/IGMPv2 querier behind a bridge then our snooping bridge is potentially not going to see any reports even though listeners exist because according to RFC4541 such reports are only forwarded to multicast routers: ----------------------------------------------------------- --------------- {Querier}---|Snoop. Switch|----{Listener} --------------- \ ^ ------- | br0 | < ??? ------- \ _-~---~_ _-~/ ~-_ ~ batman-adv \-----{Sender} \~_ cloud ~/ -~~__-__-~_/ I) MLDv1 Query: {Querier} -> flooded II) MLDv1 Report: {Listener} -> {Querier} -> br0 cannot detect the {Listener} => Packets from {Sender} need to be forwarded to all detected listeners and MLDv1/IGMPv1/IGMPv2 queriers. ----------------------------------------------------------- Note that we do not need to explicitly forward to MLDv2/IGMPv3 queriers, because these protocols have no report suppression: A bridge has no trouble detecting MLDv2/IGMPv3 listeners. Even though we do not support bridges yet we need to provide the according infrastructure already to not break compatibility later.

2014-03-22batman-adv: Add IPv4 link-local/IPv6-ll-all-nodes multicast supportLinus Lüssing
With this patch a node may additionally perform the dropping or unicasting behaviour for a link-local IPv4 and link-local-all-nodes IPv6 multicast packet, too. The extra counter and BATADV_MCAST_WANT_ALL_UNSNOOPABLES flag is needed because with a future bridge snooping support integration a node with a bridge on top of its soft interface is not able to reliably detect its multicast listeners for IPv4 link-local and the IPv6 link-local-all-nodes addresses anymore (see RFC4541, section 2.1.2.2 and section 3). Even though this new flag does make "no difference" now, it'll ensure a seamless integration of multicast bridge support without needing to break compatibility later. Also note, that even with multicast bridge support it won't be possible to optimize 224.0.0.x and ff02::1 towards nodes with bridges, they will always receive these ranges.

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).

2013-10-23batman-adv: include the sync-flags when compute the global/local table CRCAntonio Quartulli
Flags covered by TT_SYNC_MASK are kept in sync among the nodes in the network and therefore they have to be considered while computing the global/local table CRC. In this way a generic originator is able to understand if its table contains the correct flags or not. Bits from 4 to 7 in the TT flags fields are now reserved for "synchronized" flags only. This allows future developers to add more flags of this type without breaking compatibility. It's important to note that not all the remote TT flags are synchronised. This comes from the fact that some flags are used to inject an information once only.

2013-10-19batman-adv: make the TT CRC logic VLAN specificAntonio Quartulli
This change allows nodes to handle the TT table on a per-VLAN basis. This is needed because nodes may have to store only some of the global entries advertised by another node. In this scenario such nodes would re-create only a partial global table and would not be able to compute a correct CRC anymore. This patch splits the logic and introduces one CRC per VLAN. In this way a node fetching only some entries belonging to some VLANs is still able to compute the needed CRCs and still check the table correctness. With this patch the shape of the TVLV-TT is changed too because now a node needs to advertise all the CRCs of all the VLANs that it is wired to. The debug output of the local Translation Table now shows the CRC along with each entry since there is not a common value for the entire table anymore.
