Cjdns Changelog

Version 22 - Noisemaker

February 3, 2023

It's been since September 18, 2020 when cjdns v21 was tagged out, and brought only small experimental inclusion of Rust code to cjdns. v22 makes Rust a main language in which cjdns is written, and it is foreseen that in v23, almost all interactions with the OS will be done in Rust.

Major Changes

1. New protocol version v22, compatibility is maintained with v21 and v20 (no change in compatibility)
   • This new protocol version brings a new CryptoAuth protocol based on the NOISE protocol used by WireGuard® VPN. The NOISE protocol is used in all direct peering connections where both sides are v22.
   • The legacy CryptoAuth protocol remains but has been entirely re-written in Rust, the C version remains only for testing purposes.
2. RPC InterfaceController_peerStats() Now contains Integer noiseProto: 1 if using the NOISE protocol for communication
3. RPC InterfaceController_disconnectPeer() Now disconnects ALL sessions to given peer address instead of only the first
4. RPC InterfaceController_timestampPackets() has been removed, as it only affected debug logging and was rarely used
5. Libuv code is now compiled using the cjdns build system, it is nolonger compiled using gyp so python is nolonger needed to build cjdns
6. Removed cjdroute --bench which was not an accurate measure of expected performance

Minor Changes

1. Made fields of Message structure so they will be accessed through accessors - first step to move Message into Rust
2. Make cjdns Error return value use a Rust anyhow error
3. In preparation for removal of Libuv, we have replaced the following Libuv functions with Rust implementations:
   • IP Address manipulation functions: uv_inet_pton / uv_inet_pton
   • Current time: uv_now / uv_hrtime
   • Child process: uv_spawn / uv_exepath / uv_process_kill
4. We nolonger put makekeys, mkpasswd, privatetopublic, publictoip6, randombytes, and sybilsim in the main folder
   • In the future: makekeys, privatetopublic, publictoip6, and randombytes will be built as a separate optional component
   • mkpasswd will be dropped because it is too trivial to be worth maintaining
   • sybilsim will be dropped because it is nolonger maintained
5. Removed from SwitchCore.c the possibility of an interface to be "down" which never exists in reality
6. New logger for Rust code which uses the cjdns logger as a backend
7. CryptoAuth is now an (asynchronous) Iface rather than a function you call to encrypt and decrypt
