v0.14.2
|
|
-------
|
|
|
|
- Update and significantly extend µD3TN's documentation, use mkDocs for rendering it and publish it on https://d3tn.gitlab.io/ud3tn/
|
|
- Fix a potential double-free vulnerability (#233)
|
|
- Adapt the default TCP port for AAP 2.0 from 4242 to 4244 so it does not conflict with AAP
|
|
|
|
v0.14.1
|
|
-------
|
|
|
|
- Enable AAP 2.0 to use a TCP socket instead of only a POSIX IPC socket
|
|
- Fix a reachable assertion in the BPv7 parser (#227)
|
|
|
|
v0.14.0 "Nivium"
|
|
----------------
|
|
|
|
This release contains two major new features, which should be considered experimental:
|
|
|
|
1. A modular forwarding and routing interface leveraging AAP 2.0:
|
|
- AAP 2.0 is extended to allow applications to a) control and monitor outgoing links and b) perform forwarding decisions.
|
|
- A shared-secret authentication + authorization procedure is implemented — applications intending to perform privileged actions need to specify an "administrative secret" passed to µD3TN at launch through an environment variable.
|
|
- Moreover, two Python implementations of forwarding algorithms (Bundle Dispatch Modules, BDMs) are provided: a "compatibility BDM" implementing the well-known µD3TN forwarding approach and a simple static BDM based on a JSON routing table, intended to be used as a template for developing further BDMs.
|
|
2. A persistent storage feature based on SQLite, implemented as a CLA that represents a "storage-only bundle node" conceptionally:
|
|
- This makes persistent storage a "next hop" to which bundles can be sent based on the decision of the used forwarding algorithm.
|
|
- Releasing and/or dropping bundles from storage is controlled through a Protobuf-based API provided by the storage system on a dedicated endpoint.
|
|
- Authorization is ensured via a flag set through AAP 2.0 if the administrative secret has been specified.
|
|
|
|
Additionally, the following changes are contained in this release:
|
|
|
|
- Extended and new tooling for controlling µD3TN through AAP 2.0.
|
|
- Graceful Termination of CLAs and the AAP 2.0 agent.
|
|
- License change: µD3TN as a whole is now provided unter the terms of the GNU AGPL. Some parts (e.g. the Python tools and some modules) will stay under the terms of the Apache 2 and BSD licenses.
|
|
- Extend the provided Nix tooling and integration.
|
|
- Allow FIB entries to specify a "direct dispatch" flag that causes the BPA to not consult the BDM, but directly forward bundles if their destination matches.
|
|
- Restructuring of the integrated next-hop forwarding approach so it is much more modular and can be fully disabled when using an external forwarding daemon (BDM).
|
|
- Move the Python tools to the `python-ud3tn-utils` package (links are provided in Git for backward-compatibility).
|
|
- Usability improvements for the AAP and AAP 2.0 interfaces.
|
|
- Reliability and consistency improvements as well as general cleanups, bug fixes, and documentation improvements.
|
|
|
|
Note: The `aap_config.py` utility has been deprecated in favor of `aap2-config`, as it cannot set the flag required for secure operation. To continue using it, µD3TN needs to be launched with the `--allow-remote-config` commandline argument.
|
|
|
|
v0.13.0 "Maxwell"
|
|
-----------------
|
|
|
|
- Preview version of AAP 2.0 - a new Protobuf-based application interface, with Python tooling equivalent to the AAP 1.0 tools provided in tools/aap2; see doc/aap20.md
|
|
- Added a "data decoder" that can be built using `make data-decoder` and allows for inspecting captured bundles and CLA packets as well as running fuzz testing on the parsers
|
|
- Support for local node IDs not containing a terminating slash (dtn scheme) or a service number (ipn scheme)
|
|
- Moved all compile-time configuration options to config.mk with examples and defaults documented in config.mk.example
|
|
- Introduce configurable log levels - you can now select how verbose the output should be and debug log messages are disabled at compile time for more performant release builds
|
|
- Improved rate limiting for outgoing CLA connections that now also works when operating over SSH tunnels
|
|
