-**Current State**: Pairing protocol handler exists but not integrated - -**Needed**: -- Initiator receives pairing request -- Initiator sends cryptographic challenge -- Joiner signs challenge and responds -- Initiator verifies signature and completes pairing -- Both sides store paired device info - -#### 4. **Session State Management** -**Problem**: No tracking of pairing session states - -**Needed**: -- Track pending pairing sessions (who initiated what) -- Map session IDs to active pairing attempts -- Timeout handling for expired sessions -- Proper cleanup of failed pairing attempts - -#### 5. **External Address Discovery** -**Problem**: DHT advertisements contain invalid addresses - -**Current Issue**: -```rust -// Current implementation returns placeholder -pub async fn get_external_addresses(&self) -> Vec { - vec!["/ip4/127.0.0.1/tcp/0".parse().unwrap()] // Invalid! -} -``` - -**Needed**: -- Get actual listening addresses from swarm -- Implement STUN/NAT traversal for external addresses -- Filter out non-routable addresses (127.0.0.1, etc.) - -## Implementation Priority - -### High Priority (Required for Basic Pairing) - -1. **Fix External Addresses** (`get_external_addresses()`) - - Extract actual listening addresses from LibP2P swarm - - This will fix the dialing issue - -2. **Connection-Triggered Pairing Request** - - Detect when connection is for pairing vs normal operation - - Send `PairingMessage::Request` after connection established - -3. **Pairing Protocol Integration** - - Wire up existing `PairingProtocolHandler` methods - - Handle request/challenge/response/complete message flow - -### Medium Priority (Production Readiness) - -4. **Session State Tracking** - - Store pending sessions in event loop or core - - Proper timeout and cleanup handling - -5. **Error Recovery** - - Handle network failures during pairing - - Retry logic for failed connections - - User feedback for pairing failures - -### Low Priority (Nice to Have) - -6. **NAT Traversal** - - STUN server integration for external address discovery - - UPnP port mapping for better connectivity - -7. **DHT Record Cleanup** - - Remove expired pairing sessions from DHT - - Garbage collection for old records - -## Code Locations - -**Key files needing changes:** - -- `src/infrastructure/networking/core/mod.rs` - Fix `get_external_addresses()` -- `src/infrastructure/networking/core/event_loop.rs` - Add pairing request after connection -- `src/infrastructure/networking/protocols/pairing.rs` - Complete protocol handler integration -- `src/lib.rs` - Update Core pairing methods to handle async flow - -## Testing Strategy - -Once implemented, test with: - -```bash -# Terminal 1: Start Alice and generate pairing code -RUST_LOG=libp2p=debug ./target/release/spacedrive --instance alice start --enable-networking --foreground -RUST_LOG=libp2p=debug ./target/release/spacedrive network pair generate --instance alice -

-# Expected: Successful pairing with device exchange -``` - -## Architecture Assessment - -The **networking architecture is solid** - the missing pieces are implementation details rather than fundamental design issues: - -โœ… **Good**: DHT discovery, event system, protocol framework, error handling -โŒ **Missing**: Connection flow, message transmission, address resolution - -Estimated effort: **2-4 hours** to complete basic pairing functionality. \ No newline at end of file diff --git a/core-new/src/infrastructure/networking/core/event_loop.rs b/core-new/src/infrastructure/networking/core/event_loop.rs index 91acddadb..0f6f1c7b2 100644 --- a/core-new/src/infrastructure/networking/core/event_loop.rs +++ b/core-new/src/infrastructure/networking/core/event_loop.rs @@ -7,6 +7,7 @@ use super::{ use crate::infrastructure::networking::{ device::{DeviceConnection, DeviceInfo, DeviceRegistry}, protocols::{ProtocolEvent, ProtocolRegistry}, + utils::NetworkIdentity, NetworkingError, Result, }; use futures::StreamExt; @@ -15,7 +16,7 @@ use libp2p::{ swarm::{Swarm, SwarmEvent}, Multiaddr, PeerId, }; -use std::sync::Arc; +use std::{collections::HashMap, sync::Arc}; use tokio::sync::{mpsc, RwLock}; use uuid::Uuid; @@ -27,6 +28,11 @@ pub enum EventLoopCommand { protocol: String, data: Vec, }, + SendMessageToPeer { + peer_id: PeerId, + protocol: String, + data: Vec, + }, /// Publish a DHT record for pairing session discovery PublishDhtRecord { key: RecordKey, @@ -38,6 +44,10 @@ pub enum EventLoopCommand { key: RecordKey, response_channel: tokio::sync::oneshot::Sender>, }, + /// Get current listening addresses from the swarm + GetListeningAddresses { + response_channel: tokio::sync::oneshot::Sender>, + }, } /// Central event loop for processing all LibP2P events @@ -53,6 +63,9 @@ pub struct NetworkingEventLoop { /// Event sender for broadcasting events event_sender: mpsc::UnboundedSender, + + /// Network identity for signing and key operations + identity: NetworkIdentity, /// Channel for receiving shutdown signal shutdown_receiver: Option>, @@ -68,6 +81,10 @@ pub struct NetworkingEventLoop { /// Running state is_running: bool, + + /// Pending pairing sessions where we're waiting for connections + /// Maps session_id -> (peer_id, device_info, retry_count, last_attempt) + pending_pairing_connections: std::collections::HashMap)>, } impl NetworkingEventLoop { @@ -77,6 +94,7 @@ impl NetworkingEventLoop { protocol_registry: Arc>, device_registry: Arc>, event_sender: mpsc::UnboundedSender, + identity: NetworkIdentity, ) -> Self { let (shutdown_sender, shutdown_receiver) = mpsc::unbounded_channel(); let (command_sender, command_receiver) = mpsc::unbounded_channel(); @@ -86,11 +104,13 @@ impl NetworkingEventLoop { protocol_registry, device_registry, event_sender, + identity, shutdown_receiver: Some(shutdown_receiver), shutdown_sender, command_receiver: Some(command_receiver), command_sender, is_running: false, + pending_pairing_connections: HashMap::new(), } } @@ -119,8 +139,10 @@ impl NetworkingEventLoop { let device_registry = self.device_registry.clone(); let event_sender = self.event_sender.clone(); -
