batman-adv: Introduce a configurable per interface hop penalty

2020-06-26T08:37:11+00:00

In some setups multiple hard interfaces with similar link qualities
or throughput values are available. But people have expressed the desire
to consider one of them as a backup only.

Some creative solutions are currently in use: Such people are
configuring multiple batman-adv mesh/soft interfaces, wire them
together with some veth pairs and then tune the hop penalty to achieve
an effect similar to a tunable per interface hop penalty.

This patch introduces a new, configurable, per hard interface hop penalty
to simplify such setups.

batman-adv: Add multicast-to-unicast support for multiple targets

2019-03-25T09:01:13+00:00

With this patch multicast packets with a limited number of destinations
(current default: 16) will be split and transmitted by the originator as
individual unicast transmissions.

Wifi broadcasts with their low bitrate are still a costly undertaking.
In a mesh network this cost multiplies with the overall size of the mesh
network. Therefore using multiple unicast transmissions instead of
broadcast flooding is almost always less burdensome for the mesh
network.

The maximum amount of unicast packets can be configured via the newly
introduced multicast_fanout parameter. If this limit is exceeded
distribution will fall back to classic broadcast flooding.

The multicast-to-unicast conversion is performed on the initial
multicast sender node and counts on a final destination node, mesh-wide
basis (and not next hop, neighbor node basis).

batman-adv: Add throughput_override hardif genl configuration

2019-02-09T13:28:15+00:00

The B.A.T.M.A.N. V implementation tries to estimate the link throughput of
an interface to an originator using different automatic methods. It is
still possible to overwrite it the link throughput for all reachable
originators via this interface.

The BATADV_CMD_SET_HARDIF/BATADV_CMD_GET_HARDIF commands allow to set/get
the configuration of this feature using the u32
BATADV_ATTR_THROUGHPUT_OVERRIDE attribute. The used unit is in 100 Kbit/s.
If the value is set to 0 then batman-adv will try to estimate the
throughput by itself.

batman-adv: Add elp_interval hardif genl configuration

2019-02-09T13:28:15+00:00

The ELP packets are transmitted every elp_interval milliseconds on an
slave/hard-interface. This value can be changed using the configuration
interface.

The BATADV_CMD_SET_HARDIF/BATADV_CMD_GET_HARDIF commands allow to set/get
the configuration of this feature using the u32 BATADV_ATTR_ELP_INTERVAL
attribute.

batman-adv: Add orig_interval mesh genl configuration

2019-02-09T13:28:15+00:00

The OGM packets are transmitted every orig_interval milliseconds. This
value can be changed using the configuration interface.

The BATADV_CMD_SET_MESH/BATADV_CMD_GET_MESH commands allow to set/get the
configuration of this feature using the u32 BATADV_ATTR_ORIG_INTERVAL
attribute.

batman-adv: Add network_coding mesh genl configuration

2019-02-09T13:28:15+00:00

The mesh interface can use (in an homogeneous mesh) network coding, a
mechanism that aims to increase the overall network throughput by fusing
multiple packets in one transmission.

The BATADV_CMD_SET_MESH/BATADV_CMD_GET_MESH commands allow to set/get the
configuration of this feature using the BATADV_ATTR_NETWORK_CODING_ENABLED
attribute. Setting the u8 to zero will disable this feature and setting it
to something else is enabling this feature.

batman-adv: Add multicast forceflood mesh genl configuration

2019-02-09T13:28:14+00:00

The mesh interface can optimize the flooding of multicast packets based on
the content of the global translation tables. To disable this behavior and
use the broadcast-like flooding of the packets, forceflood has to be
enabled.

The BATADV_CMD_SET_MESH/BATADV_CMD_GET_MESH commands allow to set/get the
configuration of this feature using the
BATADV_ATTR_MULTICAST_FORCEFLOOD_ENABLED attribute. Setting the u8 to zero
will disable this feature (allowing multicast optimizations) and setting it
to something else is enabling this feature (forcing simple flooding).
