lib: Return number of written bytes on flow_write

2020-03-15T13:30:58+00:00

This is more in line with the write() system call and prepares for partial writes. Partial writes are disabled by default (and not yet implemented). Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Change return type of fevent to ssize_t

2020-03-15T13:26:49+00:00

The return type was still an int, but since it returns the number of events, it should be an ssize_t. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

irm: Revise naming API

2020-03-15T13:20:38+00:00

This revises the naming API to treat names (or reg_name in the source) as first-class citizens of the architecture. This is more in line with the way they are described in the article. Operations have been added to create/destroy names independently of registering. This was previously done only as part of register, and there was no way to delete a name from the IRMd. The create call now allows specifying a policy for load-balancing incoming flows for a name. The default is the new round-robin load-balancer, the previous behaviour is still available as a spillover load-balancer. The register calls will still create a name if it doesn't exist, with the default round-robin load-balancer. The tools now have a "name" section, so the format is now irm name ...

lib, ipcpd: piggyback ECDHE on flow allocation

2020-02-25T07:21:09+00:00

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

Add equal-cost multipath routing policy

2020-02-16T17:32:21+00:00

This adds an equal-cost multipath routing policy to Ouroboros, based on Nick Aerts' code. When selected, flows will send packets over all paths with equal cost (hop count). Path selection is round-robin. It does not yet take into account flows that are down. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Configure PFF from routing policy

2020-02-16T17:21:41+00:00

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.

lib: Move hashtable from lib to unicast

2020-02-16T17:19:59+00:00

The hashtable is only used for forwarding tables in the unicast IPCP. This moves the generic hashtable out of the library into the unicast IPCP to prepare a more tailored implementation specific to routing tables containing address lists.

ipcpd: Filter fqueue events in packet handlers

2020-01-25T15:02:21+00:00

The eth, udp and local IPCPs were not filtering out the event types from the flow, causing some reads when there are no packets in the queue. The types are now also organized as flags so they can be filtered more quickly if needed. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Remove support for SWIG

2019-12-08T09:03:36+00:00

This removes support for SWIG since it wasn't correctly generating all bindings. Since our API is lean, we will write the bindings for different languages from scratch. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
