From 05bd395aa2bd8a001bcafda24115b732709656a5 Mon Sep 17 00:00:00 2001 From: Ian Clarke Date: Thu, 27 Nov 2025 16:08:09 -0600 Subject: [PATCH 01/44] refactor: add PeerAddr enum for explicit address state MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 1.1 of peer identity restructuring (issue #2164). Adds PeerAddr enum with Unknown and Known(SocketAddr) variants to explicitly represent when a peer's address is unknown (e.g., sender doesn't know their own external address behind NAT) vs when it's known. This enum will be used in Connect messages to allow the first recipient to fill in the sender's address from the packet source. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- crates/core/src/ring/mod.rs | 3 +- crates/core/src/ring/peer_key_location.rs | 53 +++++++++++++++++++++++ 2 files changed, 55 insertions(+), 1 deletion(-) diff --git a/crates/core/src/ring/mod.rs b/crates/core/src/ring/mod.rs index 38c0acc75..6b2bf4a7e 100644 --- a/crates/core/src/ring/mod.rs +++ b/crates/core/src/ring/mod.rs @@ -46,7 +46,8 @@ pub(crate) use self::transient_manager::TransientConnectionManager; pub use self::live_tx::LiveTransactionTracker; pub use connection::Connection; pub use location::{Distance, Location}; -pub use peer_key_location::PeerKeyLocation; +#[allow(unused_imports)] // PeerAddr will be used as refactoring progresses +pub use peer_key_location::{PeerAddr, PeerKeyLocation}; /// Thread safe and friendly data structure to keep track of the local knowledge /// of the state of the ring. diff --git a/crates/core/src/ring/peer_key_location.rs b/crates/core/src/ring/peer_key_location.rs index 53aa67996..c33116f65 100644 --- a/crates/core/src/ring/peer_key_location.rs +++ b/crates/core/src/ring/peer_key_location.rs @@ -1,8 +1,61 @@ use super::Location; use crate::node::PeerId; use serde::{Deserialize, Serialize}; +use std::net::SocketAddr; use std::{fmt::Display, hash::Hash}; +/// Explicit representation of peer address state. +/// +/// This enum distinguishes between: +/// - `Unknown`: The address is not known by the sender (e.g., a peer doesn't know its own external address). +/// The first recipient should fill this in from the packet source address. +/// - `Known`: The address is known and explicitly specified. +#[derive(Serialize, Deserialize, Clone, PartialEq, Eq, Hash, Debug)] +#[allow(dead_code)] // Will be used as refactoring progresses +pub enum PeerAddr { + /// Address unknown - will be filled in by first recipient from packet source. + /// Used when a peer doesn't know its own external address (e.g., behind NAT). + Unknown, + /// Known address - explicitly specified. + Known(SocketAddr), +} + +#[allow(dead_code)] // Will be used as refactoring progresses +impl PeerAddr { + /// Returns the socket address if known, None otherwise. + pub fn as_known(&self) -> Option<&SocketAddr> { + match self { + PeerAddr::Known(addr) => Some(addr), + PeerAddr::Unknown => None, + } + } + + /// Returns true if the address is known. + pub fn is_known(&self) -> bool { + matches!(self, PeerAddr::Known(_)) + } + + /// Returns true if the address is unknown. + pub fn is_unknown(&self) -> bool { + matches!(self, PeerAddr::Unknown) + } +} + +impl From for PeerAddr { + fn from(addr: SocketAddr) -> Self { + PeerAddr::Known(addr) + } +} + +impl std::fmt::Display for PeerAddr { + fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result { + match self { + PeerAddr::Unknown => write!(f, ""), + PeerAddr::Known(addr) => write!(f, "{}", addr), + } + } +} + #[derive(Serialize, Deserialize, Clone, PartialEq, Eq, Hash, PartialOrd, Ord)] #[cfg_attr(test, derive(arbitrary::Arbitrary))] /// The location of a peer in the ring.

charset=UTF-8 Content-Transfer-Encoding: 8bit Peers behind NAT don't know their external address and send messages with their local address (e.g., 127.0.0.1 or 192.168.x.x). When the gateway or relay receives these messages, it needs to update the sender field with the observed transport address so responses can be routed correctly. This commit adds `rewrite_sender_addr` methods to all operation message types (Put, Get, Subscribe, Update) and calls them in p2p_protoc.rs for all inbound messages. The Connect operation already handled this via its observed_addr mechanism. Changes: - message.rs: Add rewrite_sender_addr to NetMessage and NetMessageV1 - operations/put.rs: Add rewrite_sender_addr to PutMsg - operations/get.rs: Add rewrite_sender_addr to GetMsg - operations/subscribe.rs: Add rewrite_sender_addr to SubscribeMsg - operations/update.rs: Add rewrite_sender_addr to UpdateMsg - p2p_protoc.rs: Call msg.rewrite_sender_addr(remote_addr) for inbound msgs 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- crates/core/src/message.rs | 28 ++++++++++++++++ .../src/node/network_bridge/p2p_protoc.rs | 8 +++++ crates/core/src/operations/get.rs | 17 ++++++++++ crates/core/src/operations/put.rs | 33 +++++++++++++++++++ crates/core/src/operations/subscribe.rs | 20 +++++++++++ crates/core/src/operations/update.rs | 26 +++++++++++++++ 6 files changed, 132 insertions(+) diff --git a/crates/core/src/message.rs b/crates/core/src/message.rs index 84146adc5..f37e364eb 100644 --- a/crates/core/src/message.rs +++ b/crates/core/src/message.rs @@ -5,6 +5,7 @@ use std::{ borrow::{Borrow, Cow}, fmt::Display, + net::SocketAddr, time::{Duration, SystemTime}, }; @@ -272,6 +273,17 @@ pub(crate) enum NetMessage { V1(NetMessageV1), } +impl NetMessage { + /// Updates the sender's address in the message with the observed transport address. + /// This is essential for NAT traversal - peers behind NAT don't know their external + /// address, so we update it based on what the transport layer observed. + pub(crate) fn rewrite_sender_addr(&mut self, observed_addr: SocketAddr) { + match self { + NetMessage::V1(msg) => msg.rewrite_sender_addr(observed_addr), + } + } +} + #[derive(Debug, Serialize, Deserialize, Clone)] pub(crate) enum NetMessageV1 { Connect(ConnectMsg), @@ -287,6 +299,22 @@ pub(crate) enum NetMessageV1 { Aborted(Transaction), } +impl NetMessageV1 { + /// Updates the sender's address in the message with the observed transport address. + fn rewrite_sender_addr(&mut self, observed_addr: SocketAddr) { + match self { + NetMessageV1::Put(msg) => msg.rewrite_sender_addr(observed_addr), + NetMessageV1::Get(msg) => msg.rewrite_sender_addr(observed_addr), + NetMessageV1::Subscribe(msg) => msg.rewrite_sender_addr(observed_addr), + NetMessageV1::Update(msg) => msg.rewrite_sender_addr(observed_addr), + // Connect messages are handled separately (they use observed_addr field) + NetMessageV1::Connect(_) => {} + // These don't have sender addresses to rewrite + NetMessageV1::Unsubscribed { .. } | NetMessageV1::Aborted(_) => {} + } + } +} + trait Versioned { fn version(&self) -> semver::Version; } diff --git a/crates/core/src/node/network_bridge/p2p_protoc.rs b/crates/core/src/node/network_bridge/p2p_protoc.rs index a2896cf87..7afb5ac4e 100644 --- a/crates/core/src/node/network_bridge/p2p_protoc.rs +++ b/crates/core/src/node/network_bridge/p2p_protoc.rs @@ -365,6 +365,14 @@ impl P2pConnManager { payload.observed_addr = Some(remote_addr); } } + // Rewrite sender addresses in all inbound messages with the observed + // transport address.

Changes: - Introduce ConnectionEntry struct storing sender channel and optional pub_key - Add addr_by_pub_key reverse lookup for identity-based lookups - Update all connection map operations to use SocketAddr keys - Reconstruct PeerId when needed for ring operations and queries - Maintain pub_key learning from first inbound message This allows connection management to be based on socket addresses (the transport-level identifier) while still supporting identity-based lookups when needed. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../src/node/network_bridge/p2p_protoc.rs | 194 +++++++++++++----- 1 file changed, 137 insertions(+), 57 deletions(-) diff --git a/crates/core/src/node/network_bridge/p2p_protoc.rs b/crates/core/src/node/network_bridge/p2p_protoc.rs index 7afb5ac4e..ab96907e1 100644 --- a/crates/core/src/node/network_bridge/p2p_protoc.rs +++ b/crates/core/src/node/network_bridge/p2p_protoc.rs @@ -138,12 +138,28 @@ impl NetworkBridge for P2pBridge { type PeerConnChannelSender = Sender>;

charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 4 of #2164 - Connection-based routing refactor. Key changes: - Add InboundMessage wrapper in message.rs for carrying source address - Add target_addr: Option to OperationResult for explicit routing - Thread source_addr parameter through the message processing call chain: p2p_protoc::handle_inbound_message → process_message_decoupled → handle_pure_network_message → handle_pure_network_message_v1 - Remove rewrite_sender_addr() methods from all message types (GetMsg, PutMsg, SubscribeMsg, UpdateMsg, NetMessage, NetMessageV1) This replaces the old NAT workaround (mutating message contents to fix sender addresses) with explicit address passing. The source address from the transport layer is now available for operations to use for routing decisions. Note: InboundMessage and source_addr are prepared but not yet fully utilized - operations still use embedded message addresses. Next steps will remove address fields from wire messages and have operations use source_addr for upstream routing. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- crates/core/src/message.rs | 73 ++++++++++++------- crates/core/src/node/mod.rs | 5 ++ .../src/node/network_bridge/p2p_protoc.rs | 25 ++++--- crates/core/src/operations/connect.rs | 1 + crates/core/src/operations/get.rs | 18 +---- crates/core/src/operations/mod.rs | 28 ++++--- crates/core/src/operations/put.rs | 35 +-------- crates/core/src/operations/subscribe.rs | 23 +----- crates/core/src/operations/update.rs | 27 +------ 9 files changed, 92 insertions(+), 143 deletions(-) diff --git a/crates/core/src/message.rs b/crates/core/src/message.rs index f37e364eb..df2ee5eda 100644 --- a/crates/core/src/message.rs +++ b/crates/core/src/message.rs @@ -268,20 +268,57 @@ pub(crate) trait MessageStats { fn requested_location(&self) -> Option;

charset=UTF-8 Content-Transfer-Encoding: 8bit The handle_bridge_msg function was discarding the target address passed from P2pBridge::send(), using only the message for ConnEvent::OutboundMessage. The event loop then extracted the target from msg.target().addr(), which contains the peer's self-reported address rather than the NAT-translated transport address. This caused subscribe responses to be sent to wrong addresses in NAT scenarios (e.g., 127.0.0.1:31337 instead of 172.26.0.102:31337). Fix: - Add ConnEvent::OutboundMessageWithTarget variant with explicit target_addr - Modify handle_bridge_msg to use this variant with target.addr from the PeerId - Add handler that uses target_addr directly for connection lookup 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../src/node/network_bridge/p2p_protoc.rs | 68 ++++++++++++++++++- 1 file changed, 66 insertions(+), 2 deletions(-) diff --git a/crates/core/src/node/network_bridge/p2p_protoc.rs b/crates/core/src/node/network_bridge/p2p_protoc.rs index 7390e6b3a..7d5729f51 100644 --- a/crates/core/src/node/network_bridge/p2p_protoc.rs +++ b/crates/core/src/node/network_bridge/p2p_protoc.rs @@ -599,6 +599,53 @@ impl P2pConnManager { } } } + ConnEvent::OutboundMessageWithTarget { target_addr, msg } => { + // This variant uses an explicit target address from OperationResult.target_addr, + // which is critical for NAT scenarios where the address in the message + // differs from the actual transport address we should send to. + tracing::info!( + tx = %msg.id(), + msg_type = %msg, + target_addr = %target_addr, + msg_target = ?msg.target().map(|t| t.addr()), + "Sending outbound message with explicit target address (NAT routing)" + ); + + // Look up the connection using the explicit target address + let peer_connection = ctx.connections.get(&target_addr); + + match peer_connection { + Some(peer_connection) => { + if let Err(e) = + peer_connection.sender.send(Left(msg.clone())).await + { + tracing::error!( + tx = %msg.id(), + target_addr = %target_addr, + "Failed to send message to peer: {}", e + ); + } else { + tracing::info!( + tx = %msg.id(), + target_addr = %target_addr, + "Message successfully sent to peer connection via explicit address" + ); + } + } + None => { + // No existing connection - this is unexpected for NAT scenarios + // since we should have the connection from the original request + tracing::error!( + tx = %msg.id(), + target_addr = %target_addr, + msg_target = ?msg.target().map(|t| t.addr()), + connections = ?ctx.connections.keys().collect::>(), + "No connection found for explicit target address - NAT routing failed" + ); + ctx.bridge.op_manager.completed(*msg.id()); + } + } + } ConnEvent::TransportClosed { remote_addr, error } => { tracing::debug!( remote = %remote_addr, @@ -2211,8 +2258,19 @@ impl P2pConnManager { fn handle_bridge_msg(&self, msg: Option) -> EventResult { match msg { - Some(Left((_target, msg))) => { - EventResult::Event(ConnEvent::OutboundMessage(*msg).into()) + Some(Left((target, msg))) => { + // Use OutboundMessageWithTarget to preserve the target address from + // OperationResult.target_addr.

The port was released back to the OS 3. Between release and when the test node actually bound to the port, another process could claim it Additionally, the reservation used TCP but nodes bind UDP, so a port could be free for TCP but already in use for UDP. ## Solution - Reserve both UDP (primary for Freenet nodes) and TCP (for WebSocket API) ports - Keep the sockets alive in a global RESERVED_SOCKETS map until explicitly released - Release ports just before node startup in the test macro to minimize the race window - Store port variables at outer scope so they're available for both config creation and later release The key insight is that we need to hold the port reservation until the moment before the node binds, then release it to allow the node to bind to that exact port. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- crates/core/src/test_utils.rs | 37 +++++++++++++++++++++------- crates/freenet-macros/src/codegen.rs | 30 +++++++++++++++------- 2 files changed, 49 insertions(+), 18 deletions(-) diff --git a/crates/core/src/test_utils.rs b/crates/core/src/test_utils.rs index 23dee3d06..89b549acb 100644 --- a/crates/core/src/test_utils.rs +++ b/crates/core/src/test_utils.rs @@ -8,7 +8,7 @@ use std::{ }; use clap::ValueEnum; -use dashmap::DashSet; +use dashmap::{DashMap, DashSet}; use freenet_stdlib::{ client_api::{ClientRequest, ContractRequest, WebApi}, prelude::*, @@ -815,25 +815,40 @@ mod test { // Port reservation utilities for integration tests static RESERVED_PORTS: Lazy> = Lazy::new(DashSet::new); +/// Holds sockets to keep ports reserved until explicitly released. +/// The tuple stores (UdpSocket, TcpListener) for each port. +static RESERVED_SOCKETS: Lazy> = + Lazy::new(DashMap::new); /// Reserve a unique localhost TCP port for tests. /// -/// Ports are allocated by binding to an ephemeral listener to ensure the port -/// is currently free, then tracked in a global set so concurrent tests do not -/// reuse the same value.

charset=UTF-8 Content-Transfer-Encoding: 8bit Key changes: - Replace `peer: PeerId` with `pub_key: TransportPublicKey` + `peer_addr: PeerAddr` - Add PeerAddr enum with Unknown/Known variants for explicit address state - Add accessor methods: pub_key(), addr(), socket_addr(), peer() - Add constructors: new(), with_unknown_addr(), with_location() - Implement Ord/PartialOrd based on socket address This separates cryptographic identity (pub_key) from network address (peer_addr), enabling proper handling of peers behind NAT who don't know their external address.

Changes: - Introduce ConnectionEntry struct storing sender channel and optional pub_key - Add addr_by_pub_key reverse lookup for identity-based lookups - Update all connection map operations to use SocketAddr keys - Reconstruct PeerId when needed for ring operations and queries - Maintain pub_key learning from first inbound message This allows connection management to be based on socket addresses (the transport-level identifier) while still supporting identity-based lookups when needed. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../src/node/network_bridge/p2p_protoc.rs | 341 ++++++++++++------ 1 file changed, 236 insertions(+), 105 deletions(-) diff --git a/crates/core/src/node/network_bridge/p2p_protoc.rs b/crates/core/src/node/network_bridge/p2p_protoc.rs index dfaada9c2..b4dadc93a 100644 --- a/crates/core/src/node/network_bridge/p2p_protoc.rs +++ b/crates/core/src/node/network_bridge/p2p_protoc.rs @@ -76,30 +76,61 @@ impl P2pBridge { } impl NetworkBridge for P2pBridge { - async fn drop_connection(&mut self, peer: &PeerId) -> super::ConnResult<()> { - self.accepted_peers.remove(peer);

charset=UTF-8 Content-Transfer-Encoding: 8bit Addresses Nacho's architectural feedback to avoid raw SocketAddr in protocol layer. Uses ObservedAddr newtype to wrap transport-layer addresses, making the address semantics explicit at the type level. Changes: - Add ObservedAddr newtype in transport/mod.rs - Update Operation trait to use Option for source_addr - Update all operation implementations (connect, get, put, subscribe, update) - Update node/mod.rs and p2p_protoc.rs to use ObservedAddr - Wrap incoming source_addr in ObservedAddr::new() at transport boundary - Convert back to SocketAddr at network send boundaries The conversion to raw SocketAddr happens at transport boundaries: - build_op_result() converts for target_addr - network_bridge.send() calls use .socket_addr() 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../src/node/network_bridge/p2p_protoc.rs | 104 +++++++++++++++--- crates/core/src/operations/connect.rs | 16 ++- crates/core/src/operations/get.rs | 42 +++++-- crates/core/src/operations/mod.rs | 62 +++++++---- crates/core/src/operations/put.rs | 58 +++++++--- crates/core/src/operations/subscribe.rs | 51 ++++++--- crates/core/src/operations/update.rs | 35 +++--- 7 files changed, 271 insertions(+), 97 deletions(-) diff --git a/crates/core/src/node/network_bridge/p2p_protoc.rs b/crates/core/src/node/network_bridge/p2p_protoc.rs index b4dadc93a..0ed1d8b28 100644 --- a/crates/core/src/node/network_bridge/p2p_protoc.rs +++ b/crates/core/src/node/network_bridge/p2p_protoc.rs @@ -30,8 +30,8 @@ use crate::node::{MessageProcessor, PeerId}; use crate::operations::{connect::ConnectMsg, get::GetMsg, put::PutMsg, update::UpdateMsg}; use crate::ring::Location; use crate::transport::{ - create_connection_handler, OutboundConnectionHandler, PeerConnection, TransportError, - TransportKeypair, TransportPublicKey, + create_connection_handler, ObservedAddr, OutboundConnectionHandler, PeerConnection, + TransportError, TransportKeypair, TransportPublicKey, }; use crate::{ client_events::ClientId, @@ -390,16 +390,16 @@ impl P2pConnManager { payload.observed_addr = Some(remote_addr); } } - // Rewrite sender addresses in all inbound messages with the observed - // transport address.

charset=UTF-8 Content-Transfer-Encoding: 8bit This commit applies all wire protocol cleanup changes from PR #2169 on top of the rebased PR #2167 base: - Remove sender field from GetMsg, PutMsg, SubscribeMsg, UpdateMsg, ConnectMsg - Use upstream_addr for routing responses instead of embedded sender fields - Delete transient_manager.rs (no longer needed) - Update freenet-macros code generation for new message structure The routing logic now derives the response target from the connection's observed address (upstream_addr) rather than trusting sender fields in messages. This is more reliable for NAT traversal scenarios. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- crates/core/src/node/mod.rs | 8 +- .../src/node/network_bridge/p2p_protoc.rs | 255 +++----- crates/core/src/node/p2p_impl.rs | 2 - crates/core/src/operations/connect.rs | 578 ++++++++---------- crates/core/src/operations/get.rs | 122 ++-- crates/core/src/operations/mod.rs | 20 +- crates/core/src/operations/put.rs | 137 +++-- crates/core/src/operations/subscribe.rs | 144 +++-- crates/core/src/operations/update.rs | 76 ++- crates/core/src/ring/connection_manager.rs | 168 +++-- crates/core/src/ring/mod.rs | 4 - crates/core/src/ring/transient_manager.rs | 295 --------- crates/core/src/router/isotonic_estimator.rs | 36 +- crates/core/src/test_utils.rs | 147 ----- crates/core/src/tracing/mod.rs | 33 +- crates/core/src/transport/mod.rs | 34 -- crates/core/tests/operations.rs | 7 +- crates/freenet-macros/src/codegen.rs | 45 +- crates/freenet-macros/src/lib.rs | 7 +- crates/freenet-macros/src/parser.rs | 20 +- tests/test-app-1/package-lock.json | 22 +- 21 files changed, 838 insertions(+), 1322 deletions(-) delete mode 100644 crates/core/src/ring/transient_manager.rs diff --git a/crates/core/src/node/mod.rs b/crates/core/src/node/mod.rs index bf17154d4..d0c1e2cab 100644 --- a/crates/core/src/node/mod.rs +++ b/crates/core/src/node/mod.rs @@ -61,7 +61,7 @@ use crate::operations::handle_op_request;

Network namespace isolation This change provides marginal improvement for self-hosted runners where port competition is higher. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- crates/freenet-macros/src/codegen.rs | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/crates/freenet-macros/src/codegen.rs b/crates/freenet-macros/src/codegen.rs index 152c483ea..c4547a04f 100644 --- a/crates/freenet-macros/src/codegen.rs +++ b/crates/freenet-macros/src/codegen.rs @@ -410,12 +410,14 @@ fn generate_node_builds(args: &FreenetTestArgs) -> TokenStream { builds.push(quote! { tracing::info!("Building node: {}", #node_label); - // Release reserved ports just before binding to minimize race window - freenet::test_utils::release_local_port(#network_port_var); - freenet::test_utils::release_local_port(#ws_port_var); let built_config = #config_var.build().await?; let mut node_config = freenet::local_node::NodeConfig::new(built_config.clone()).await?; #connection_tuning + + // Release ports immediately before building node (minimizes race window) + freenet::test_utils::release_local_port(#network_port_var); + freenet::test_utils::release_local_port(#ws_port_var); + let (#node_var, #flush_handle_var) = node_config .build_with_flush_handle(freenet::server::serve_gateway(built_config.ws_api).await) .await?; From 59b8a9deaf2733dfd5b727380ff39e7f8cc62aa9 Mon Sep 17 00:00:00 2001 From: Ian Clarke Date: Sun, 30 Nov 2025 22:07:55 -0600 Subject: [PATCH 43/44] docs: document port collision race in test framework MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The test framework has an unavoidable race between releasing reserved ports and nodes binding to them. On busy self-hosted runners, another process may occasionally grab the port in this window. This is a transient issue - retriggering typically succeeds. Complete fixes would require SO_REUSEADDR, sysctl port ranges, network namespace isolation, or test framework restructuring. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- crates/core/src/test_utils.rs | 14 ++++++++++++++ 1 file changed, 14 insertions(+) diff --git a/crates/core/src/test_utils.rs b/crates/core/src/test_utils.rs index 6fa10ae6d..c41034d4a 100644 --- a/crates/core/src/test_utils.rs +++ b/crates/core/src/test_utils.rs @@ -829,6 +829,20 @@ static RESERVED_SOCKETS: Lazy anyhow::Result { const MAX_ATTEMPTS: usize = 128; for _ in 0..MAX_ATTEMPTS { From 814ad708aad96203de991cf510405c02cec84e0c Mon Sep 17 00:00:00 2001 From: Ian Clarke Date: Mon, 1 Dec 2025 18:11:56 -0600 Subject: [PATCH 44/44] fix: use upstream_addr for subscribe operation NAT routing (#2171) Co-authored-by: Claude --- .../src/node/network_bridge/p2p_protoc.rs | 68 ++++++++++++++++++- crates/core/src/operations/connect.rs | 32 ++++----- crates/core/src/operations/get.rs | 36 ++++++---- crates/core/src/operations/subscribe.rs | 37 +++++----- 4 files changed, 124 insertions(+), 49 deletions(-) diff --git a/crates/core/src/node/network_bridge/p2p_protoc.rs b/crates/core/src/node/network_bridge/p2p_protoc.rs index 50b521aa4..c81be75a6 100644 --- a/crates/core/src/node/network_bridge/p2p_protoc.rs +++ b/crates/core/src/node/network_bridge/p2p_protoc.rs @@ -603,6 +603,53 @@ impl P2pConnManager { } } } + ConnEvent::OutboundMessageWithTarget { target_addr, msg } => { + // This variant uses an explicit target address from OperationResult.target_addr, + // which is critical for NAT scenarios where the address in the message + // differs from the actual transport address we should send to. + tracing::info!( + tx = %msg.id(), + msg_type = %msg, + target_addr = %target_addr, + msg_target = ?msg.target().map(|t| t.addr()), + "Sending outbound message with explicit target address (NAT routing)" + ); + + // Look up the connection using the explicit target address + let peer_connection = ctx.connections.get(&target_addr); + + match peer_connection { + Some(peer_connection) => { + if let Err(e) = + peer_connection.sender.send(Left(msg.clone())).await + { + tracing::error!( + tx = %msg.id(), + target_addr = %target_addr, + "Failed to send message to peer: {}", e + ); + } else { + tracing::info!( + tx = %msg.id(), + target_addr = %target_addr, + "Message successfully sent to peer connection via explicit address" + ); + } + } + None => { + // No existing connection - this is unexpected for NAT scenarios + // since we should have the connection from the original request + tracing::error!( + tx = %msg.id(), + target_addr = %target_addr, + msg_target = ?msg.target().map(|t| t.addr()), + connections = ?ctx.connections.keys().collect::>(), + "No connection found for explicit target address - NAT routing failed" + ); + ctx.bridge.op_manager.completed(*msg.id()); + } + } + } ConnEvent::TransportClosed { remote_addr, error } => { tracing::debug!( remote = %remote_addr, @@ -2266,8 +2313,19 @@ impl P2pConnManager { fn handle_bridge_msg(&self, msg: Option) -> EventResult { match msg { - Some(Left((_target, msg))) => { - EventResult::Event(ConnEvent::OutboundMessage(*msg).into()) + Some(Left((target, msg))) => { + // Use OutboundMessageWithTarget to preserve the target address from + // OperationResult.target_addr.
