ipcpd: Add ipcpd over UDP/IPv6

2025-09-10T06:19:52+00:00

This adds an IPCP that runs over UDP/IPv6. It's structured like the eth-dix and eth-llc in that it builds two separate binaries: ipcpd-udp4 and ipcpd-udp6. The IRM CLI is backwards compatible in that type 'udp' will resolve to type 'udp4'. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Configure link-state at bootstrap

2025-08-18T06:29:23+00:00

The link-state component had some values defined in the source such as link-state advertisement interval, link timeout period and the PFF recalculation time. These can now be configured from the config file or via "irm ipcp bootstrap" on the command line. Signed-off-by: Dimitri Staessens

ipcpd: Update DHT for unicast layer

2025-08-06T10:34:15+00:00

This is a rewrite of the DHT for name-to-address resolution in the unicast layer. It is now integrated as a proper directory policy. The dir_wait_running function is removed, instead the a DHT peer is passed on during IPCP enrolment. Each DHT request/response gets a random 64-bit ID ('cookie'). DHT messages to the same peer are deduped, except in the case when the DHT is low on contacts. In that case, it will contact the per it received at enrolment for more contacts. To combat packet loss, these messages are not deduped by means of a 'magic cookie', chosen at random when the DHT starts. The DHT parameters (Kademlia) can be set using the configfile or the IRM command line tools: if DIRECTORY_POLICY == DHT [dht_alpha (default: 3)] [dht_k (default: 8)] [dht_t_expire (default: 86400)] [dht_t_refresh (default: 900)] [dht_t_replicate (default: 900)] This commit also adds support for a protocol debug level (PP). Protocol debugging for the DHT can be enabled using the DEBUG_PROTO_DHT build flag. The DHT has the following message types: DHT_STORE, sent to k peers. Not acknowledged. DHT_STORE --> [2861814146dbf9b5|ed:d9:e2:c4]. key: bcc236ab6ec69e65 [32 bytes] val: 00000000c4e2d9ed [8 bytes] exp: 2025-08-03 17:29:44 (UTC). DHT_FIND_NODE_REQ, sent to 'alpha' peers, with a corresponding response. This is used to update the peer routing table to iteratively look for the nodes with IDs closest to the requested key. DHT_FIND_NODE_REQ --> [a62f92abffb451c4|ed:d9:e2:c4]. cookie: 2d4b7acef8308210 key: a62f92abffb451c4 [32 bytes] DHT_FIND_NODE_RSP <-- [2861814146dbf9b5|ed:d9:e2:c4]. cookie: 2d4b7acef8308210 key: a62f92abffb451c4 [32 bytes] contacts: [1] [a62f92abffb451c4|9f:0d:c1:fb] DHT_FIND_VALUE_REQ, sent to 'k' peers, with a corresponding response. Used to find a value for a key. Will also send its closest known peers in the response. DHT_FIND_VALUE_REQ --> [2861814146dbf9b5|ed:d9:e2:c4]. cookie: 80a1adcb09a2ff0a key: 42dee3b0415b4f69 [32 bytes] DHT_FIND_VALUE_RSP <-- [2861814146dbf9b5|ed:d9:e2:c4]. cookie: 80a1adcb09a2ff0a key: 42dee3b0415b4f69 [32 bytes] values: [1] 00000000c4e2d9ed [8 bytes] contacts: [1] [a62f92abffb451c4|9f:0d:c1:fb] Also removes ubuntu 20 from appveyor config as it is not supported anymore.

tools: Fix missing eth-dix in "irm ipcp create"

2023-12-17T12:23:49+00:00

The irm ipcp create tool had the ipcpd-eth-dix missing in the help. Updated the help text where PARAM = {options list} to where PARAM in {options list} and some other small fixes. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

include: Rename layer.layer_name to layer.name

2023-11-29T08:57:29+00:00

The layer_info had a member layer_name which is a bit redundant. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Rename ipcp_info to ipcp_list_info

2023-11-29T08:57:29+00:00

The ipcp_info struct / message contains information only used for listing IPCPs, and I will reuse the ipcp_info name for general IPCP information common to all IPCPs such as name and type. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

irmd: Add configuration file support

2023-03-08T14:59:37+00:00

This adds initial support for configuration files using the C99 TOML parser (to be installed separately from https://github.com/cktan/tomlc99). The default location for the IRMd configuration file is /etc/ouroboros/irmd.conf. This is configurable at build time. An example file will be installed in the configuration directory with the name irmd.conf.example. Config file support can be disabled using the DISABLE_CONFIGFILE build option. There were some refactors and changes to the configuration messages and protobuf files. This works towards consolidation of protobuf C as an option for more generic handling of serialization/deserialization of various messages.

ipcpd: refactor IPCP configuration

2023-02-13T20:10:11+00:00

The ipcp configuration struct now has internal structures for the different IPCPs and for IPCP components of the unicast IPCP. Split the very long IPCP main loop into individual handler functions. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
