## 1. Executive Summary
|
|
|
|
`nx9-wg` is a sovereign, self-hosted, Linux-native VPN and network control plane built directly around the Linux kernel's in-tree WireGuard implementation (`wireguard.ko`).
|
|
|
|
Rather than functioning as a fragile user interface wrapper that shells out to external command-line utilities (`wg`, `ip`, `nft`, `sysctl`), `nx9-wg` establishes an integrated, single-binary architecture. It combines **authoritative SQLite desired-state persistence**, **direct kernel Netlink execution** (RTNETLINK and WireGuard Generic Netlink), **in-process Netfilter firewall/NAT compilation** (`libnftables.so.1`), **continuous closed-loop reconciliation**, a **multi-format native CLI**, and an **embedded zero-dependency Single Page Application (SPA) Web UI**.
|
|
|
|
---
|
|
|
|
## 2. The NX9 Philosophy in Implementation
|
|
|
|
Every design and architectural choice in `nx9-wg` directly reflects the core philosophy of the **NX9 Ecosystem** ([https://nx9.in](https://nx9.in)):
|
|
|
|
| NX9 Principle | Core Intent | `nx9-wg` Implementation |
|
|
| :--- | :--- | :--- |
|
|
| 🔑 **Operator Ownership** | Full control over binaries, configurations, databases, keys, and backups with zero dependency on cloud-hosted control planes. | 100% local operation. Private keys, configuration data, and encryption parameters never leave the operator's host. |
|
|
| 🖥️ **Self-Hosting First** | Built to be deployed and operated effortlessly by a single administrator without requiring Kubernetes or external infrastructure. | Self-contained single executable. Bootstrapped with a single command (`nx9-wg init`), running seamlessly under standard systemd. |
|
|
| ⚡ **Simplicity Over Complexity** | One binary, one configuration file, one SQLite database, one administrator. | No multi-daemon orchestration, no external message queues, no Node.js runtime, no Python scripts, and zero shell wrappers. |
|
|
| 🛡️ **Privacy by Default** | Zero analytics, zero telemetry collection, zero third-party tracking, and zero assumptions of external cloud connectivity. | No phone-home telemetry. Completely air-gapped capable with all static assets, fonts, and scripts embedded in the binary. |
|
|
| 🔒 **Security by Design** | Modern cryptography, strict invariants, and append-only audit logging embedded from day one. | Argon2id password hashing, SHA-256 token digests, X25519 key generation, single-admin database constraint (`CHECK (id=1)`), and strict secret redaction. |
|
|
| 🔧 **Operational Excellence** | Diagnostics, backup/restore, migration tools, CLI management, and comprehensive documentation built-in. | Multi-subsystem automated health inspections, atomic online SQLite `VACUUM INTO` snapshots with SHA-256 manifests, and 100% CLI parity. |
|
|
| ⏳ **Long-Term Stability** | Avoid dependency churn. Build software that remains understandable and maintainable years into the future. | Built in stable native Rust (Edition 2024), standard SQLite 3 storage, standard TOML configuration, and POSIX-compliant systemd integration. |
|
|
| 🌐 **Open Source First** | 100% free and open-source software under permissive licensing. | Dual-licensed under `MIT OR Apache-2.0`. Complete freedom to inspect, audit, build, and extend. |
|
|
| ♾️ **Zero Vendor Lock-In** | Standard data formats, open protocols, and zero proprietary cloud lock-in. | Standard SQLite database, standard WireGuard `.conf` files, standard RFC-compliant JSON/YAML/CSV output formats, and open Netlink sockets. |

*Disadvantages: Fragile process spawning, race conditions, lack of atomic state, broken host routing, vulnerability to configuration drift, and heavy runtime dependency footprints.*

## 7. Closed-Loop Reconciliation & Convergence

Reconciliation is the foundational control loop that bridges authoritative SQLite state with the Linux kernel:

### The Six Reconciliation Lifecycle States
|
|
1. **`Plan`**: Read-only calculation of drift between SQLite and kernel.
|
|
2. **`Applying`**: In-progress dispatch of native mutations across execution planes.
|
|
3. **`Verifying`**: Querying live kernel state to confirm applied changes took effect.
|
|
4. **`Converged`**: 100% synchronization achieved with zero remaining drift.
|
|
5. **`PartialFailure`**: One or more execution planes failed during apply (e.g. permission error).
|
|
6. **`DriftRemains`**: Apply completed without fatal error, but post-verification detected unapplied state.
|
|
|
|

|
|
|
|
## 8. Embedded Single Page Application (SPA) & WebSockets
|
|
|
|
The `nx9-wg` frontend is a zero-dependency HTML5/CSS/JavaScript SPA embedded directly into the Rust binary:
|
|
|
|
- **Zero External Toolchains**: No Node.js, npm, Webpack, Vite, React, or external CDN dependencies.
|
|
- **Embedded In-Memory Delivery**: Bundled at compile-time via `include_str!()` and served from memory.
|
|
- **Design Tokens**: Custom CSS token system ([`crates/nx9-wg-ui/src/css.rs`](file:///home/sunil/Programs/nx9-wg/crates/nx9-wg-ui/src/css.rs)) supporting Light and Dark modes.
|
|
- **Real-Time WebSocket Stream**: Subscribes to `ws://<host>/api/v1/ws` for live handshakes and drift alerts without polling.
|
|
- **15 Interactive Views**:
|
|
1. `#dashboard` — System overview, uptime, interface/peer counts, health cards.
|
|
2. `#interfaces` — WireGuard interface CRUD, listen port, MTU, state toggles.
|
|
3. `#peers` — Enrolled peer table, real-time handshakes, profile resolution, `.conf` export, SVG QR modal.
|
|
4. `#networks` — Subnet network ranges, CIDR masks, available IP inspector.
|
|
5. `#routes` — Kernel route definitions, gateway assignments, interface scoping.
|
|
6. `#firewall` — nftables packet filtering rules in `table inet nx9_wg`, priority sorting.
|
|
7. `#nat` — Managed subnet NAT masquerade status and instant toggle.
|
|
8. `#forwarding` — Kernel IPv4/IPv6 packet forwarding status and toggle.
|
|
9. `#reconciliation` — Real-time kernel drift overview, action plan table, interactive Apply button.
|
|
10. `#diagnostics` — Automated multi-subsystem health checks with remediation hints.
|
|
11. `#live-state` — Raw Linux Netlink telemetry, active kernel interfaces, live routing table.
|
|
12. `#settings` — Key-value appliance parameters and danger zone reset controls.
|
|
13. `#backups` — Online SQLite backup snapshots list, instant backup creation, `.db` download.
|
|
14. `#audit` — Append-only security and administrative audit trail.
|
|
15. `#administrator` — Admin account verification, password rotation, and one-time API token generation.
|
|
|

|
|
|
|
## 9. REST API & WebSocket Protocol Reference
|
|
|
|
### Authentication Mechanisms
|
|
- **Session Cookie**: `nx9_session=<UUID>` returned via `POST /api/v1/auth/login`.
|
|
- **Bearer Token**: `Authorization: Bearer nx9_<UUID>_<SECRET>` passed in HTTP headers.
|
|
|

## 11. Security Model & Capability Isolation
|
|
|
|
### A. Single Administrator Identity
|
|
- Database-level integrity constraint: `CHECK (id = 1)` in `admins` table.
|
|
- Eliminates multi-tenant privilege escalation and role-confusion attack surfaces.
|
|
|
|
### B. Credential Protection
|
|
- **Passwords**: Hashed with Argon2id using unique cryptographic salts.
|
|
- **API Tokens**: Stored exclusively as SHA-256 digests in SQLite; raw tokens are displayed once upon creation.
|
|
- **Secret Redaction**: Private keys, preshared keys, and password hashes implement custom `std::fmt::Debug` implementations returning `[REDACTED]`.
|
|
|
|

## 12. Disaster Recovery, Backups & Upgrades
|
|
|
|
### Atomic Online Backups
|
|
- Uses SQLite `VACUUM INTO` to produce non-blocking, consistent binary database snapshots while the daemon is actively serving traffic.
|
|
- Generates SHA-256 manifest records for each snapshot.
|
|
|
|
### Safe Rollback Workflow
|
|
```

## 13. Release Engineering & Deployment Lifecycle
|
|
|
|
### Automated Packaging Pipeline ([`scripts/package-release.sh`](file:///home/sunil/Programs/nx9-wg/scripts/package-release.sh))
|
|
Generates self-contained, reproducible distribution archives in `target/dist/`:
|
|
- `nx9-wg-v1.0.0-linux-x86_64.tar.gz` (7.8 MB)
|
|
- `nx9-wg-v1.0.0-linux-x86_64.tar.xz` (5.0 MB)
|
|
- `nx9-wg-v1.0.0-linux-x86_64.sha256` (Cryptographic checksum manifest)
|
|
|
|
### Production Filesystem Layout & Permissions
|
|
```
|
|
/usr/local/bin/nx9-wg 0755 root:root - Native Executable Binary
|
|
/etc/nx9-wg/ 0750 root:root - Configuration Directory
|
|

|
|
/var/lib/nx9-wg/ 0700 root:root - State & SQLite Directory
|
|

|
|
├── nx9-wg.db-wal 0600 root:root - WAL Journal
|
|
├── admin-password 0600 root:root - Initial Bootstrap Password
|
|
└── backups/ 0700 root:root - Backup Snapshots Directory
|
