Description

This PR implements NetworkManager integration for Rosenpass, providing a D-Bus service that allows NetworkManager to manage Rosenpass post-quantum secure connections.

Closes #83 /claim #83

What’s Changed

New NetworkManager Plugin Package

• Added networkmanager-plugin/ crate with full D-Bus integration
• Implements D-Bus service at eu.rosenpass.NetworkManager
• Supports multiple connection management via NetworkManager

Key Features

• D-Bus Service Interface with 8 methods for complete NetworkManager control
• Connection Management - activate, deactivate, and monitor Rosenpass connections
• Configuration System - TOML-based per-connection configuration
• Process Isolation - each connection runs in a separate Rosenpass process
• State Monitoring - real-time connection state tracking with D-Bus signals
• Systemd Integration - includes service file with security hardening

Implementation Details

D-Bus Interface Methods

• ActivateConnection(connection_uuid: s)
• DeactivateConnection(connection_uuid: s)
• GetConnectionStatus(connection_uuid: s) -> (status: s)
• ListConnections() -> (connections: as)
• AddConnection(connection_uuid: s, config_path: s)
• RemoveConnection(connection_uuid: s)
• ReloadConfiguration()
• GetVersion() -> (version: s)

D-Bus Signals

• ConnectionStateChanged(connection_uuid: s, state: s)
• ErrorOccurred(connection_uuid: s, error_message: s)

Testing

• Unit tests for configuration loading and conversion
• Integration tested with D-Bus commands
