From 8e8621f76094f1594f26baf49e6e571306f7aad7 Mon Sep 17 00:00:00 2001 From: coffeegrind123 Date: Thu, 2 Oct 2025 18:42:55 +0300 Subject: [PATCH] feat: Add complete AmneziaWG kernel module support and UI integration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit implements full AmneziaWG support including kernel module building, obfuscation parameter management, and conditional UI display. ## Kernel Module Support - Build amneziawg kernel module for Alpine LTS kernel 6.12.50 - Multi-stage Docker build with kernel_module_builder - Pre-compile module during image build for target kernel - Graceful fallback to standard WireGuard if build fails - Copy built module to /lib/modules/ in final image ## Database & Schema Changes - Add AWG obfuscation parameters to interface schema: * Core params: jc, jmin, jmax, s1, s2, h1-h4 * Advanced params: s3, s4, i1-i5, j1-j3, itime - Set sensible defaults with QUIC packet mimic for i1 - Add migration SQL with all AWG columns - Implement Zod validation for all parameters with amneziawg-go constraints ## Backend Implementation - Create awg-params.ts utility for random parameter generation - Modify wgHelper.ts to include AWG params in server/client configs - Add isUsingAwg() detection function - Auto-generate random AWG parameters on first run - Update API endpoint to return AWG status flag - Add #utils alias to nuxt.config.ts ## Frontend/UI Changes - Add comprehensive AWG parameter form fields in interface.vue - Conditional display: show AWG fields only when AWG is active - Show informative message when AWG is not enabled - All 23 parameters editable with validation hints - Organized in "AmneziaWG Obfuscation Parameters" section ## Documentation - Add AMNEZIAWG_BUILD.md with build architecture details - Add AWG_UI_IMPLEMENTATION.md with usage guide - Add amnezia-kernel-module.md documentation - Document all parameters, constraints, and usage ## Features - Automatic AWG parameter randomization for each installation - Comprehensive validation (frontend, backend, database) - Clean UI that adapts to WireGuard implementation in use - Support for AWG 1.0 and 1.5 advanced obfuscation features - Compatible with Alpine Linux LTS kernel 6.12.50 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- AMNEZIAWG_BUILD.md | 264 +++++++++++++++ AWG_UI_IMPLEMENTATION.md | 301 ++++++++++++++++++ Dockerfile | 41 +++ .../advanced/config/amnezia-kernel-module.md | 168 ++++++++++ src/app/pages/admin/interface.vue | 131 ++++++++ src/nuxt.config.ts | 2 + src/server/api/admin/interface/index.get.ts | 3 + .../database/migrations/0000_short_skin.sql | 20 ++ .../database/repositories/interface/schema.ts | 24 ++ .../database/repositories/interface/types.ts | 119 +++++++ src/server/database/sqlite.ts | 38 ++- src/server/utils/awg-params.ts | 176 ++++++++++ src/server/utils/wgHelper.ts | 53 ++- 13 files changed, 1337 insertions(+), 3 deletions(-) create mode 100644 AMNEZIAWG_BUILD.md create mode 100644 AWG_UI_IMPLEMENTATION.md create mode 100644 docs/content/advanced/config/amnezia-kernel-module.md create mode 100644 src/server/utils/awg-params.ts diff --git a/AMNEZIAWG_BUILD.md b/AMNEZIAWG_BUILD.md new file mode 100644 index 00000000..3080c0d1 --- /dev/null +++ b/AMNEZIAWG_BUILD.md @@ -0,0 +1,264 @@ +# AmneziaWG Build Implementation + +## Summary + +The Dockerfile now builds and includes **complete AmneziaWG support** with two components: + +1. **amneziawg-tools** -
