Changelog

This file documents recent notable changes to this project. The format of this file is based on Keep a Changelog, and this project adheres to Semantic Versioning.

0.10.0 - 2024-02-23

Changed

  • Changed struct Configuration to enum Configs and defined configuration by module.

0.9.3 - 2024-02-16

Added

  • Add RequestCode::Shutdown to shutdown the host.

0.9.2 - 2023-12-07

Added

  • Add RequestCode::SemiSupervisedModels to update semi-supervised models of all Hogs.

0.9.1 - 2023-09-06

Added

  • RequestCode::ProcessList to request agent to collect host's process list.

Fixed

  • Fix clippy warnings.

0.9.0 - 2023-07-27

Changed

  • Change to respond with an immediate Ok message when receiving an EchoRequest message instead of calling the handler's function.

0.8.2 - 2023-06-15

Added

  • Introduced new request code: RequestCode:TrustedUserAgentList
    • RequestCode::TrustedUserAgentList: This new request code facilitates the REview sending a list of trusted user-agents to the agent. This request code is followed by a Vec<String> parameter, which is a list of trusted user-agents.

0.8.1 - 2023-06-05

Added

  • New Request Code: RequestCode:EchoRequest. This addition to the request code library is designed specifically for network latency testing, also commonly referred to as ping testing. When a request is made to a daemon using the RequestCode::EchoRequest, the daemon will respond with an empty tuple. This allows users to measure round trip time between the client and the server without relying on the content of the response.

0.8.0 - 2023-05-24

Changed

  • The transfer data types of the following request codes have been changed:

    • RequestCode:InternalNetworkList
    • RequestCode:AllowList
    • RequestCode:BlockList

    Prior to this update, these request codes were using a string array to transfer data. This approach has been replaced by the HostNetworkGroup data type.

    This change is backwards incompatible. Users are encouraged to update their request handling to accommodate the HostNetworkGroup data type.

0.7.1 - 2023-05-17

Added

  • Introduced two new request codes: RequestCode::AllowList and RequestCode::BlockList.

    • RequestCode::AllowList: This new request code facilitates REview to transmit the allow list to an agent. This request code is followed by a list of IP prefixes (represented as Vec<String>), which specifies the IP ranges allowed to communicate.
    • RequestCode::BlockList: This new request code enables REview to send the block list to an agent. This request code also follows a Vec<String> parameter which carries a list of IP prefixes that are to be blocked from communication.

    Each of these IP prefixes are in the format of "10.20.81.1/24".

0.7.0 - 2023-05-11

Changed

  • Upgrade minimum supported Rust version (MSRV) to 1.65.
  • Upgrade rustls to 0.21.
  • Upgrade quinn to 0.10.
  • Remove agent_id and host_id fields from AgentInfo and client_handshake, as they are no longer passed to server manually. It's required that the server retrieve "{agent_id}@{host_id}" from Common Name (CN) of certificate used by the client.

0.6.1 - 2023-04-17

Added

  • RequestCode::GetConfig to get config toml file
  • RequestCode::SetConfig to set config toml file
  • More fields to Configuration
  • RequestCode::DeleteSamplingPolicy
  • RequestCode::InternalNetworkList

Fixed

  • Fix the trusted_domain_list update failure.

0.6.0 - 2022-11-28

Added

  • Add RequestCode::SamplingPolicyList for updating sampling policies.
  • Add RequestCode::ReloadFilterRule for updating traffic filtering rules of piglet.

Removed

  • ResourceUsage and functions related with getting resource usage.

0.5.0 - 2022-11-07

Changed

  • Requires Rust 1.64 or later.
  • Requires quinn 0.9.0 or later.
  • server_handshake takes &Connection instead of &mut IncomingBiStreams.

0.4.1 - 2022-08-24

Added

  • Add RequestCode::TorExitNodeList for updating tor exit nodes.

0.4.0 - 2022-06-26

Added

  • When the received request code is not recognized, the response code is set to RequestCode::Unknown.
  • message::send_request and message::send_forward_request can accept any type implementing Into<u32> as code.

Changed

  • RequestCode no longer implements Serialize and Deserialize; it should be converted to/from u32 for serialization/deserialization.
  • message::recv_request_raw returns the request code as u32 instead of RequestCode.
  • A client sending an unknown request code will receive an error message.

0.3.0 - 2022-06-24

Added

  • message::server_handshake receives a handshake message and sends a response.
  • AgentInfo implements Display.
  • AgentInfo::key to obtain the agent's key.

Changed

  • Requires Rust 1.57.0 or later.
  • message::handshake is now message::client_handshake to differentiate itself from the server handshake.
  • HandshakeError::NewerProtocolRequired has been replaced with HandshakeError::IncompatibleProtocol, which carries both the current version and the required version.
  • HandhsakeError::StreamError has been replaced with HandshakeError::ConnectionLost.

0.2.7 - 2022-06-08

Added

  • messages::handshake and the types it uses: AgentInfo and HandshakeError. It sends a handshake request and processes the response.

0.2.6 - 2022-05-27

Added

  • request::Handler defines the interface for a request handler for an agent.
  • request::handle handles requests for an agent.

0.2.5 - 2022-05-23

Added

  • send_ok and send_err to send a response.

0.2.4 - 2022-05-18

Added

  • handle_resource_usage to handle the ResourceUsage request.

0.2.3 - 2022-05-17

Added

  • RequestCode supports serialization with serde.
  • recv_request_raw to receive a request without deserialization.
  • send_request to send a request with serialization.
  • send_forward_request to send a RequestCode::Forward request.

0.2.2 - 2022-05-16

Added

  • frame::send_raw to send raw bytes in a frame.

0.2.1 - 2022-05-12

Added

  • RequestCode::ReloadConfig to request agent to reload configuration
  • RequestCode::ResourceUsage to request agent to collect resource usage stats

0.2.0 - 2022-05-11

Added

  • RequestCode that identifies the type of request.

Changed

  • recv_frame, recv_raw_frame, and recv_raw_frame are now under frame; use frame::recv, frame::recv_raw, and frame::recv_raw_frame instead.

0.1.1 - 2022-05-10

Added

  • recv_raw_frame to receive length-delimited frames without deserializing them.

0.1.0 - 2022-05-09

Added

  • send_frame and recv_frame to send and receive length-delimited frames.
