Primary interface `wg0` is protected from deletion and disabling. +- **Optional Third-Party Upstream Interfaces**: In-process parser and validator for standard third-party WireGuard `.conf` files (validated against ProtonVPN), creating managed `Upstream` interfaces (e.g. `proton0`) with exactly one provider peer. +- **REST API Endpoints**: Added `POST /api/v1/interfaces/upstreams/preview` (dry-run configuration validation with secret redaction), `POST /api/v1/interfaces/upstreams/import` (atomic SQLite persistence and reconciliation), and `POST /api/v1/interfaces/{id}/restart` (link teardown and re-synchronization). +- **Native CLI Commands**: Added `nx9-wg interface upstream` command suite (`list`, `show`, `import`, `status`, `enable`, `disable`, `restart`, `delete`) and `nx9-wg interface restart`. +- **Read-Only SPA CLI Console**: Embedded web-based CLI runner enforcing a strict read-only command allowlist and output secret scrubbing. +- **Reconciliation Hardening**: Added orphan kernel interface detection and removal during `apply()`, backed by empty-desired-state safety guards preventing destructive cleanup on database read failures. +- **Provider AllowedIPs Preservation**: Upstream provider peers retain full-tunnel AllowedIPs (`0.0.0.0/0, ::/0`) in WireGuard Cryptokey Routing without modifying or hijacking host Linux FIB default routes. + +### Changed +- **Optional Local Listen Ports**: Changed `Interface.listen_port` to `Option` across domain models, Netlink device configuration, REST API, and SQLite database (`0005_optional_listen_port.sql`). +- **Dynamic Port Web UI**: Unspecified listen ports are rendered as `Auto (Dynamic)` rather than a fabricated `51820`. + +### Fixed +- **Local Listen Port Collision (errno=-98 / EADDRINUSE)**: Fixed upstream interfaces defaulting omitted `ListenPort` to `51820`, which collided with `wg0`. Omitted listen ports now remain `None`, allowing Linux WireGuard to bind an ephemeral dynamic UDP port. +- **Reconciliation Dynamic Port Drift**: Suppressed false listen-port drift when desired `listen_port` is `None` and the kernel reports a dynamic port. +- **Provider Endpoint Port Independence**: Ensured remote destination `[Peer] Endpoint` port (e.g. `37.19.199.155:51820`) is strictly preserved and never assigned as the local interface listen port. + +### Interoperability Status +- **ProtonVPN**: ProtonVPN WireGuard `.conf` files import and synchronize cleanly into Linux kernel devices (`proton0`) with dynamic local listen ports. Upstream connectivity status is classified as `interop_pending_external_validation` (pending external provider session/endpoint resolution, not an NX9-WG implementation defect). + ## [1.0.0] — 2026-08-18 NX9-WG 1.0.0 is the first production release of the native Linux WireGuard + network control plane. diff --git a/Cargo.lock b/Cargo.lock index 907ac3c..aa5570d 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -1785,7 +1785,7 @@ dependencies = [ [[package]] name = "nx9-wg" -version = "1.0.0" +version = "1.1.0" dependencies = [ "axum", "base64", @@ -1807,7 +1807,7 @@ dependencies = [ [[package]] name = "nx9-wg-api" -version = "1.0.0" +version = "1.1.0" dependencies = [ "axum", "chrono", @@ -1832,7 +1832,7 @@ dependencies = [ [[package]] name = "nx9-wg-core" -version = "1.0.0" +version = "1.1.0" dependencies = [ "argon2", "base64", @@ -1852,7 +1852,7 @@ dependencies = [ [[package]] name = "nx9-wg-db" -version = "1.0.0" +version = "1.1.0" dependencies = [ "chrono", "ipnet", @@ -1869,7 +1869,7 @@ dependencies = [ [[package]] name = "nx9-wg-network" -version = "1.0.0" +version = "1.1.0" dependencies = [ "async-trait", "chrono", @@ -1890,7 +1890,7 @@ dependencies = [ [[package]] name = "nx9-wg-ui" -version = "1.0.0" +version = "1.1.0" dependencies = [ "chrono", "nx9-wg-core", @@ -1901,7 +1901,7 @@ dependencies = [ [[package]] name = "nx9-wireguard" -version = "1.0.0" +version = "1.1.0" dependencies = [ "async-trait", "base64", diff --git a/Cargo.toml b/Cargo.toml index 00e82d7..6eefaff 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -10,7 +10,7 @@ members = [ [workspace.package] license = "MIT OR Apache-2.0" -version = "1.0.0" +version = "1.1.0" edition = "2024" authors = ["NX9 Authors "] repository = "https://github.com/thakares/nx9-wg" diff --git a/README.md b/README.md index 7981964..015fb24 100644 --- a/README.md +++ b/README.md @@ -4,7 +4,7 @@ ![SQLite](https://img.shields.io/badge/SQLite-Embedded-blue) ![Platform](https://img.shields.io/badge/Platform-Linux-lightgrey) ![License](https://img.shields.io/badge/License-MIT%20OR%20Apache--2.0-green) -![Version](https://img.shields.io/badge/Version-v1.0.0-purple) +![Version](https://img.shields.io/badge/Version-v1.1.0-purple) > **Sovereign, self-hosted, Linux-native VPN and network control plane built directly around the kernel's WireGuard implementation.** @@ -57,21 +57,22 @@ Rather than functioning as a user interface wrapper that shells out to external --- -## 2.
