ipcpd: Fix addresses in RIB entries

2025-08-18T06:29:39+00:00

The entries of the RIB were broken as some paths in FUSE were checked against the old entry format. Updated the address format to use a dot to avoid escaping colons and spaces and be friendlier to command line tools such as 'cat'. 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.
