lib, ipcpd: piggyback ECDHE on flow allocation

2020-02-25T07:21:09Z

The initial implementation for the ECDHE key exchange was doing the key exchange after a flow was established. The public keys are now sent allowg on the flow allocation messages, so that an encrypted tunnel can be created within 1 RTT. The flow allocation steps had to be extended to pass the opaque data ('piggybacking'). Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Configure PFF from routing policy

2020-02-16T17:21:41Z

The Packet Forwarding Function (PFF) was user-configurable using the irm tool. However, this isn't really wanted since the PFF is dictated by the routing algorithm. This moves the responsability for selecting the correct PFF from the network admin to the unicast IPCP implementation. Each routing policy now has to specify which PFF it will use.

build: Refactor normal to unicast

2019-07-29T17:36:45Z

This completes the renaming of the normal IPCP to the unicast IPCP in the sources, to get everything consistent with the documentation. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Handle local IPCP case when parsing config

2019-03-28T13:52:59Z

The default case in the configuration parsing prints an erroneous "Unknown IPCP type" message when a local IPCP is bootstrapped. The IPCP_LOCAL type is now handled separately (no action needed). Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Revise UDP IPCP

2019-03-18T10:09:31Z

The UDP IPCP now uses a fixed server UDP port (default 3435) for all communications. This allows passing firewalls more easily since only a single port needs to be opened. The client port can be fixed as well if needed (default random). It uses an internal eid, so the MTU of the UDP layer is reduced by 4 bytes, similar to the Ethernet IPCPs.

include: Add a flow_join operation for broadcast

2018-12-27T15:08:56Z

This adds a new flow_join operaiton for broadcast, which is a much safer solution than overloading destination name semantics. The internal API now also has a different IPCP_FLOW_JOIN operation. The IRMd doesn't need to query broadcasts IPCPs for the name, it can just check if an IPCP with the layer name exists. The broadcast IPCP doesn't need to implement the query proxy call anymore.

ipcpd: Add broadcast IPCP

2018-10-24T09:58:49Z

This adds a broadcast IPCP that allows us to easily create multicast applications. The broadcast IPCP accepts flows for ".mc". A tool, obc (Ouroboros broadcast), is added that sends and reads a message to a broadcast layer. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

tools: Specify QoS cube for data transfer flows

2018-10-19T10:24:23Z

The ipcp connect command can now set a specific qos cube for data transfer flows. For management flows, the tool ignores this and defaults to raw until data flows are stable enough. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
