dtn's Issues

dtrd: local endpoint registration

Local endpoints should require registration of client applications before we accept bundles for them. This prevents other users from spamming these endpoints.

dtrd: validate bundle extensions

when receiving a bundle we should validate the extensions it has and act according to the requirements if we do not know them

support udp as additional convergance layer

See RFC 7122

tcpcl: refactor to use actix

this should (hopefully) make the code simpler and more reasonable to interact with the other actix components.

This might mean building an actix actor out of that crate, or (maybe better) transform it to some kind of general purpose adapter over tcp sessions that has a Stream like interface.

dtrd: setting persistence

General settings and the configuration of nodes and routes should be persistent across restarts

tcpcl: ensure tls validation

This includes validating:

crls
ocsp
other requirements from section 4.4 of rfc 9174

User documentation

Build some kind of documentation on:

how to generally run this system
how to interact with it from the cli
how to interact with it from other clients
how to interact with other bundle protocol nodes

tcpcl: transfer length extension

support sending and receiving the transfer length extension. If received it should be used to allocated a large enough chunk of memory to read the entire bundle

tcpcl: do not send last ack before the bundle is actually handled

currently the tcpcl layer always sends a xferAck once a given xferSegment has been recieived.
We should defer sending the last xferAck of a bundle until the bundle has actually been persistent.
This allows our peer to be certain that we have fully received and processed the bundle

dtrd: bundle persistence

Bundles should be persistent across restarts of dtrd (and should stop consuming memory all the time if they can not be forwarded). Expired bundles should be regularly deleted.
