From 188a484c30398bce98673f54ca65afe129fef80d Mon Sep 17 00:00:00 2001 From: Ian Clarke Date: Mon, 1 Dec 2025 18:34:16 -0600 Subject: [PATCH 1/2] fix: NAT address handling in subscribe/seeding operations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Consolidates changes from PRs #2172, #2174, and #2175: This builds on PR #2191 (wire protocol cleanup) and adds: - Fix seeding/subscribe operations to handle PeerAddr::Unknown for NAT scenarios - Gateway properly fills in observed addresses from packet source - Improved subscriber address tracking in seeding manager - Update live_tx and connection tests for new address model NOTE: This PR requires review - previous PRs (#2174, #2175) had CHANGES_REQUESTED from Nacho. Submitting consolidated changes for fresh review. 🤖 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 | 234 ++----- crates/core/src/node/p2p_impl.rs | 117 +++- .../core/src/node/testing_impl/in_memory.rs | 4 +- crates/core/src/operations/connect.rs | 597 ++++++++---------- crates/core/src/operations/get.rs | 142 +++-- crates/core/src/operations/mod.rs | 24 +- crates/core/src/operations/put.rs | 137 ++-- crates/core/src/operations/subscribe.rs | 169 +++-- crates/core/src/operations/update.rs | 80 ++- crates/core/src/ring/connection_manager.rs | 168 +++-- crates/core/src/ring/live_tx.rs | 68 +- crates/core/src/ring/mod.rs | 46 +- crates/core/src/ring/seeding.rs | 21 +- 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 | 24 +- 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 +- 24 files changed, 1095 insertions(+), 1356 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;
