⚠️ RÈGLES CRITIQUES À TOUJOURS RESPECTER:

1. RPCD Script Naming: Nom fichier = objet ubus (luci.system-hub)
2. Menu Path Matching: Path menu = fichier vue (system-hub/overview.js)
3. Permissions: RPCD = 755, CSS/JS = 644
   • Auto-fix: ./secubox-tools/fix-permissions.sh --local (avant commit)
   • Auto-fix remote: ./secubox-tools/fix-permissions.sh --remote (après deploy)
4. Validation: Toujours exécuter ./secubox-tools/validate-modules.sh avant commit
   • 7 checks automatiques: RPCD naming, menu paths, view files, RPCD permissions, JSON syntax, ubus naming, htdocs permissions
5. CSS Variables: Toujours utiliser var(--sh-*), jamais hardcoder les couleurs
6. Dark Mode: Toujours supporter dark mode avec [data-theme="dark"]
7. Typography: Inter (texte), JetBrains Mono (valeurs numériques)
8. Gradient Effects: Utiliser --sh-primary → --sh-primary-end pour dégradés

Project Overview

SecuBox is a comprehensive security and network management suite for OpenWrt. The repository contains 13 LuCI application packages that provide dashboards for security monitoring, network intelligence, access control, bandwidth management, and system administration.

Build Commands

OpenWrt SDK Build

# Build a single package
make package/luci-app-<module-name>/compile V=s

# Clean build for a package
make package/luci-app-<module-name>/clean
make package/luci-app-<module-name>/compile V=s

# Install package to staging directory
make package/luci-app-<module-name>/install

Testing Packages

# Transfer to router
scp bin/packages/*/base/luci-app-*.ipk root@192.168.1.1:/tmp/

# Install on router
ssh root@192.168.1.1
opkg install /tmp/luci-app-*.ipk
/etc/init.d/rpcd restart

Validation

# Fix file permissions FIRST (CRITICAL)
./secubox-tools/fix-permissions.sh --local

# Run comprehensive module validation (RECOMMENDED - 7 checks)
./secubox-tools/validate-modules.sh
# Checks:
# 1. RPCD script names vs ubus objects

# 3. View files have menu entries
# 4. RPCD script permissions (755)
# 5. JSON syntax validation
# 6. ubus object naming convention
# 7. htdocs file permissions (644 for CSS/JS) ← NEW

# Validate shell scripts (RPCD backends)
shellcheck luci-app-*/root/usr/libexec/rpcd/*

# Validate JSON files
find . -name "*.json" -exec jsonlint {} \;

# Run automated repair tool
./secubox-tools/secubox-repair.sh

# Fix permissions on deployed router
./secubox-tools/fix-permissions.sh --remote

# Run diagnostics
./secubox-tools/secubox-debug.sh luci-app-<module-name>

Local Build (Replicates GitHub Actions)

The local-build.sh script allows you to build and test packages locally, replicating the GitHub Actions workflows:

# Validate all packages (syntax, JSON, shell scripts)
./secubox-tools/local-build.sh validate

# Build all packages for x86_64
./secubox-tools/local-build.sh build

# Build single package
./secubox-tools/local-build.sh build luci-app-system-hub

# Build for specific architecture
./secubox-tools/local-build.sh build --arch aarch64-cortex-a72

# Full validation + build
./secubox-tools/local-build.sh full

# Clean build artifacts
./secubox-tools/local-build.sh clean

Supported architectures:

• x86-64 - PC, VMs (default)
• aarch64-cortex-a53 - ARM Cortex-A53 (ESPRESSObin)
• aarch64-cortex-a72 - ARM Cortex-A72 (MOCHAbin, RPi4)
• aarch64-generic - Generic ARM64
• mips-24kc - MIPS 24Kc (TP-Link)
• mipsel-24kc - MIPS LE (Xiaomi, GL.iNet)

The script automatically:

• Downloads and caches the OpenWrt SDK
• Configures feeds (packages, luci) with correct branch for version
• Copies your packages to the SDK
• Builds packages (.apk for 25.12+, .ipk for older versions)
• Collects artifacts in build/<arch>/

Package Format Support:

• OpenWrt 25.12+ and SNAPSHOT: .apk format (new Alpine-based package manager)
• OpenWrt 24.10 and earlier: .ipk format (opkg package manager)

Environment variables:

• OPENWRT_VERSION - OpenWrt version (default: 24.10.5, also supports: 25.12.0-rc1, 23.05.5, SNAPSHOT)
• SDK_DIR - SDK directory (default: ./sdk)
• BUILD_DIR - Build output directory (default: ./build)
• CACHE_DIR - Download cache directory (default: ./cache)

Architecture

LuCI Package Structure

All SecuBox modules follow a standard LuCI application structure:

luci-app-<module-name>/
├── Makefile                              # OpenWrt package definition
├── README.md                             # Module documentation
├── htdocs/luci-static/resources/
│   ├── view/<module-name>/               # JavaScript UI views
│   │   ├── overview.js                   # Main dashboard view
│   │   └── *.js                          # Additional views
│   └── <module-name>/
│       ├── api.js                        # RPC API client module
│       └── dashboard.css                 # Module-specific styles
└── root/
    ├── etc/config/<module-name>          # UCI configuration (optional)
    └── usr/
        ├── libexec/rpcd/
        │   └── luci.<module-name>        # RPCD backend script (MUST use luci. prefix!)
        └── share/
            ├── luci/menu.d/              # Menu JSON definition
            │   └── luci-app-<module-name>.json
            └── rpcd/acl.d/               # ACL permissions JSON
                └── luci-app-<module-name>.json

Frontend-Backend Communication

1. Frontend (JavaScript): Located in htdocs/luci-static/resources/
   • Views use LuCI’s form and view classes
   • API calls via api.js module using L.resolveDefault()
   • UI components from ui.js (Dropdown, Checkbox, Combobox, etc.)
2. Backend (RPCD): Located in root/usr/libexec/rpcd/
   • Shell scripts that implement RPC methods
   • Must output JSON to stdout
   • Methods are called via ubus: ubus call <module> <method>
3. Menu Definition: root/usr/share/luci/menu.d/luci-app-<module>.json
   • Defines menu structure and navigation
   • Specifies view paths and dependencies
4. ACL Definition: root/usr/share/rpcd/acl.d/luci-app-<module>.json
   • Defines access control for ubus methods
   • Maps read/write permissions to user groups

Critical Naming Conventions

IMPORTANT: The following naming rules are MANDATORY for modules to work correctly:

1. RPCD Script Must Match ubus Object Name

The RPCD script filename MUST exactly match the ubus object name used in JavaScript:

// In JavaScript (htdocs/luci-static/resources/view/*/):
var callStatus = rpc.declare({
    object: 'luci.cdn-cache',  // ← This object name
    method: 'status'
});

# RPCD script filename MUST match:
root/usr/libexec/rpcd/luci.cdn-cache  # ← Must be exactly 'luci.cdn-cache'

Common Error: If the names don’t match, you’ll get:

• RPC call to luci.cdn-cache/status failed with error -32000: Object not found
• Command failed: Method not found

Solution: All RPCD scripts MUST use the luci. prefix:

• ✅ Correct: luci.cdn-cache, luci.system-hub, luci.wireguard-dashboard
• ❌ Wrong: cdn-cache, system-hub, wireguard-dashboard

2. Menu Paths Must Match View File Locations

Menu JSON path entries MUST correspond to actual view files:

// In menu.d/luci-app-netifyd-dashboard.json:
{
    "action": {
        "type": "view",
        "path": "netifyd-dashboard/overview"  // ← Must match file location
    }
}

# View file MUST exist at:
htdocs/luci-static/resources/view/netifyd-dashboard/overview.js
#                                  ↑ Same path as menu ↑

Common Error: If paths don’t match:

• HTTP error 404 while loading class file '/luci-static/resources/view/netifyd/overview.js'

Solution: Ensure menu paths match directory structure:

• ✅ Correct: Menu path netifyd-dashboard/overview → file view/netifyd-dashboard/overview.js
• ❌ Wrong: Menu path netifyd/overview → file view/netifyd-dashboard/overview.js

3. ubus Object Naming Convention

All ubus objects MUST start with luci. prefix:

// ✅ Correct:
object: 'luci.cdn-cache'
object: 'luci.system-hub'
object: 'luci.wireguard-dashboard'

// ❌ Wrong:
object: 'cdn-cache'
object: 'systemhub'

4. Validation Before Deployment

ALWAYS run validation before deploying:

./secubox-tools/validate-modules.sh

This script checks:

• RPCD script names match ubus objects
• Menu paths match view file locations
• View files have corresponding menu entries
• RPCD scripts are executable
• JSON files are valid syntax
• ubus objects follow naming convention

Makefile Structure

Each package Makefile must define:

• PKG_NAME: Package name (must match directory)
• PKG_VERSION: Version number
• PKG_RELEASE: Package release number
• LUCI_TITLE: Display title in LuCI
• LUCI_DEPENDS: Package dependencies (e.g., +luci-base +rpcd)
• LUCI_DESCRIPTION: Brief description
• PKG_MAINTAINER: Maintainer name and email
• PKG_LICENSE: License (typically Apache-2.0)

The Makefile includes luci.mk from the LuCI build system which handles installation.

Common Development Patterns

Creating a New Module

1. Copy template: cp -r templates/luci-app-template luci-app-newmodule
2. Update Makefile with new PKG_NAME, LUCI_TITLE, etc.
3. Create directory structure under htdocs/ and root/
4. Implement RPCD backend in shell
5. Create JavaScript views
6. Define menu and ACL JSON files

RPCD Backend Pattern

RPCD backends are shell scripts that:

• Parse $1 for the method name
• Output valid JSON using printf or echo
• Use case statements for method routing
• Source UCI config if needed: . /lib/functions.sh

Example:

#!/bin/sh
case "$1" in
    list)
        echo '{ "status": {}, "stats": {} }'
        ;;
    call)
        case "$2" in
            status)
                # Output JSON
                printf '{"running": true, "version": "1.0.0"}\n'
                ;;
        esac
        ;;
esac

JavaScript View Pattern

Views extend L.view and implement load() and render():

'use strict';
'require view';
'require form';
'require <module>/api as API';

return L.view.extend({
    load: function() {
        return Promise.all([
            API.getStatus(),
            API.getStats()
        ]);
    },

    render: function(data) {
        var m, s, o;
        m = new form.Map('config', _('Title'));
        s = m.section(form.TypedSection, 'section');
        // Add form fields...
        return m.render();
    }
});

Common Issues and Solutions

RPC Errors: “Object not found” or “Method not found”

Error: RPC call to luci.cdn-cache/status failed with error -32000: Object not found

Cause: RPCD script name doesn’t match ubus object name in JavaScript

Solution:

1. Check JavaScript files for ubus object name:

   grep -r "object:" luci-app-*/htdocs --include="*.js"
   

2. Rename RPCD script to match exactly (including luci. prefix):

   mv root/usr/libexec/rpcd/cdn-cache root/usr/libexec/rpcd/luci.cdn-cache
   

3. Restart RPCD on router:

   /etc/init.d/rpcd restart
   

HTTP 404 Errors: View Files Not Found

Error: HTTP error 404 while loading class file '/luci-static/resources/view/netifyd/overview.js'

Cause: Menu path doesn’t match actual view file location

Solution:

1. Check menu JSON for path:

   grep '"path":' root/usr/share/luci/menu.d/*.json
   

2. Verify view file exists at matching location:

   ls htdocs/luci-static/resources/view/
   

3. Update menu path to match file location OR move file to match menu path

RPCD Not Responding

After installing/updating a package:

/etc/init.d/rpcd restart
/etc/init.d/uhttpd restart

Menu Not Appearing

Check that:

1. Menu JSON is valid: jsonlint root/usr/share/luci/menu.d/*.json
2. ACL grants access: Check root/usr/share/rpcd/acl.d/*.json
3. Dependencies are installed: Check Makefile LUCI_DEPENDS
4. Menu path matches view file location (see above)

Build Failures

Common causes:

1. Missing fields in Makefile (PKG_NAME, LUCI_TITLE, etc.)
2. Invalid JSON syntax in menu.d or acl.d
3. RPCD script not executable (chmod +x needed)
4. Wrong include path (should be include ../../luci.mk)
5. RPCD script name doesn’t match ubus object (must use luci. prefix)

Use repair tool: ./secubox-tools/secubox-repair.sh

Quick Diagnosis

Run the validation script to check all naming conventions:

./secubox-tools/validate-modules.sh

Development Workflow

1. Make changes to module files
2. Run validation checks (CRITICAL):

   ./secubox-tools/validate-modules.sh
   # Or use the local build tool:
   ./secubox-tools/local-build.sh validate
   

3. Test JSON syntax: jsonlint <file>.json
4. Test shell scripts: shellcheck <script>
5. Build and test package locally (recommended):

   # Build single package
   ./secubox-tools/local-build.sh build luci-app-<name>
   
   # Or build with manual SDK:
   make package/luci-app-<name>/compile V=s
   

6. Install on test router and verify functionality
7. Run repair tool if needed: ./secubox-tools/secubox-repair.sh
8. Commit changes and push (triggers CI validation)
9. Create tag for release: git tag -a v1.0.0 -m "Release 1.0.0"

Important Notes

• CRITICAL: RPCD script names MUST match ubus object names (use luci. prefix)
• CRITICAL: Menu paths MUST match view file directory structure
• CRITICAL: Always run ./secubox-tools/validate-modules.sh before committing
• All modules use Apache-2.0 license
• RPCD backends must be executable (chmod +x)
• JavaScript files use strict mode: 'use strict';
• Menu entries require proper dependency chain
• ACL must grant both ubus call and luci-cgi access
• UCI config files are optional (many modules don’t need them)
• All packages build as architecture all (no compiled code)
