Full Changelog: v3.1.0...v3.2.0

[3.1.0] - 2025-11-09

Added

• Display: clear and force a full E-Paper refresh when the active WAN interface changes (e.g. eth0 -> wlan1) to avoid ghosting and show the updated interface/IP immediately. (commit 478b8ee)
• Status collection: prefer kernel default route when runtime WAN state is missing and provide a wan_state_path injection point for testing/overrides.
• Renderer: improve network line formatting by removing the redundant "WAN" prefix and suppressing non-actionable "[WAN] unknown" messages; reserve footer area to prevent text overlap.

Changed

• Backwards-compatible StatusCollector initialization handling in epd_daemon — older installs without the new wan_state_path parameter are tolerated.

Notes

• These are backward-compatible improvements (minor release). See commit 478b8ee for details and files changed: azazel_pi/core/display/status_collector.py, epd_daemon.py, renderer.py.
  • Suricata integration for network threat detection
  • AI-based threat evaluation pipeline and scoring
  • Basic TUI and CLI utilities for status and control
  • Initial installer and documentation to deploy core services

v3.0.0 — EPD integration, redesigned display UI and startup reliability improvements

[3.0.0] - 2025-11-09

EPD (e-paper) integration, redesigned display UI, and startup reliability improvements.

Added

• Full E-Paper (EPD) integration with the Azazel-Pi platform.
  • New renderer and display pipeline for EPD devices.
  • EPD_SKIP_BOOT_ANIM support to skip the boot animation when desired.
  • scripts/epd_hello.py included for quick EPD smoke-tests and verification.
• Configurable periodic full-refresh to reduce e-paper ghosting (--full-refresh-minutes).
• Local timezone display: convert StatusCollector timestamps from UTC to the system local timezone for correct local time presentation on the E-Paper.

Changed

• Major UX/visual changes for the E-Paper display (layout and formatting updates).
• Renderer startup sequence improved:
  • Attempt driver.init() before display to wake hardware from sleep.
  • Increased startup delay and avoid sleep() after boot animation so SPI handle remains open.
• Retry logic for transient SPI/GPIO errors added to improve robustness on flaky hardware.
• systemd service and deployment improvements (drop-in/override provided for more reliable start-up and environment handling).
• Allow shell expansion for environment defaults in service unit files where applicable.

Fixed

• Local time offset when displaying timestamps on the E-Paper fixed by converting UTC timestamps to the system local timezone before formatting.
• Various startup race conditions mitigated by adjusting initialization order and delays.

Notes

• This is a major release (3.0.0) because it introduces a new, visible feature (EPD integration) and significant UI/behavior changes that add new concepts to the product.
• Backwards compatibility: runtime behavior for systems without EPD hardware is preserved. EPD integration is opt-in via installer flags (--enable-epd, --epd-emulate, --epd-force) and environment variables.
• To provision the EPD host Wi-Fi during install, set EPD_WIFI_SSID and EPD_WIFI_PSK env vars when running scripts/install_azazel_complete.sh.

Upgrade / Deployment

1. If you use the installer, run with --enable-epd to include EPD integration and optionally --epd-emulate for emulation mode.
2. If enabling EPD on a device with SPI hardware, ensure SPI is enabled in the device firmware (e.g. dtparam=spi=on in /boot/config.txt) and reboot if required.
3. After deployment, verify:
   • EPD daemon (azazel-epd.service) status using systemctl status azazel-epd.service.
   • Local time is displayed correctly on the E-Paper.
   • Full-refresh occurs at the configured interval if enabled.

Testing / Verification

• Deploy to a test device with EPD hardware or run with --epd-emulate to validate display behavior.
• Run scripts/epd_hello.py to confirm renderer availability.
• Review systemd logs: journalctl -u azazel-epd.service -n 200 --no-pager.

v2.2.0: Internal Network QoS Control

Release v2.2.0: Internal Network QoS Control

🎯 Overview

Version 2.2.0 introduces comprehensive Internal Network QoS (Quality of Service) Control for privilege-based traffic shaping and security enforcement within the LAN. This feature enables differentiated bandwidth allocation, MAC address verification, and ARP spoofing protection for trusted devices.

✨ Major Features

1. Mark-Based Traffic Classification

• Premium (0x10): High-priority devices with guaranteed bandwidth
• Standard (0x20): Normal priority for regular devices
• Best Effort (0x30): Default class for unclassified traffic
• Restricted (0x40): Limited bandwidth for suspicious/untrusted devices

2. Three Security Modes

• none: Marking only, no enforcement (safe testing mode)
• verify: Drop packets from privileged IPs with mismatched MAC addresses
• lock: verify mode + static ARP entries to prevent spoofing

3. Dynamic Priority Adjustment

• Score-based automatic class reassignment
• Configurable thresholds and bias factors
• Optional daemon (azazel_priorityd) for continuous evaluation

4. HTB Traffic Shaping

• Hierarchical Token Bucket (HTB) implementation using tc
• Per-class rate/ceil configuration via YAML
• Idempotent initialization (safe to re-run)

🔧 New Components

Scripts

• bin/azazel-traffic-init.sh: Initialize tc HTB classes and nftables infrastructure
• bin/azazel-qos-apply.sh: Apply privilege-based rules from CSV with mode selection
• bin/azazel-qos-menu.sh: Interactive TUI for privileged host management

Services

• services/azazel_priorityd.py: Dynamic priority daemon with score-based logic
• systemd/azazel-traffic-init.service: One-shot init service

Azazel-Pi v2.0.0 - AI-Powered Edge Defense with 4-Mode Operation

Release v2.0.0 - AI-Powered Edge Defense with 4-Mode Operation

Release Date: November 6, 2025

🎉 Major Release Highlights

This major release introduces AI-powered threat evaluation, a new 4-mode defensive system with observe-only capability, and exception blocking for known threats. The system now features offline-first AI evaluation with optional cloud integration, providing faster response times and reduced resource usage.

🚀 Breaking Changes & Upgrade Notes

New 4-Mode Defensive System

The system now operates in four modes instead of three:

• Normal (NEW): Observe-only mode with zero traffic control overhead
• Portal: Light restrictions with captive portal redirect
• Shield: Moderate restrictions with delay and bandwidth shaping
• Lockdown: Maximum restrictions with complete blocking

Migration: Existing configurations will continue to work. The new normal mode is triggered when threat scores fall below the new t0_normal threshold (default: 20).

New Configuration Requirements

Add these sections to /etc/azazel/azazel.yaml:

thresholds:
  t0_normal: 20      # NEW: Normal mode threshold
  t1_shield: 50      # Existing
  t2_lockdown: 80    # Existing

actions:
  normal:            # NEW: Normal mode action
    delay_ms: 0
    shape_kbps: null
    block: false

soc:                 # NEW: Security Operations Center settings
  denylist_ips: []
  critical_signatures:
    - "ET EXPLOIT"
    - "ET MALWARE"
    - "ET TROJAN"
    - "Critical Infrastructure Attack"

✨ New Features

1. AI-Powered Threat Evaluation

Mock LLM - Fast Deterministic Classifier

• Purpose: Rapid evaluation of known threat patterns
• Performance: <50ms response time, <10MB memory footprint
• Coverage: Handles 80-90% of alerts with high confidence
• Categories: SQL Injection, XSS, RCE, Path Traversal, Brute Force, DoS, Malware, Botnet, Reconnaissance, Exploit
• Operation: Fully offline, no external dependencies

Hybrid Evaluation Engine

• Architecture: 3-tier cascade (Legacy Rules → Mock LLM → Ollama)
• Intelligent routing: Known threats processed by Mock LLM, unknown threats escalated to Ollama
• Weighted scoring:
  • Known threats: Legacy 60% + Mock LLM 40%
  • Unknown threats: Ollama 70% + Mock LLM 30%
• Fallback: Gracefully degrades to offline-only if Ollama unavailable

Ollama Integration (Optional)

• Model: Qwen2.5-1.5B optimized for edge deployment
• Use case: Deep analysis of ambiguous or novel threats
• Performance: 2-5s response time, 2-3GB memory usage
• Coverage: Handles 10-20% of complex alerts
• Setup: Automated installation via scripts/setup_ollama.sh

2. Normal Mode - Observe-Only Operation

Key Characteristics

• Zero overhead: No tc qdisc, no nftables rules, no traffic shaping
• Full connectivity: All network traffic flows unrestricted
• Continuous monitoring: Suricata IDS remains active
• Threat scoring: AI evaluation continues in background
• Auto-escalation: Automatically transitions to portal/shield/lockdown if threats increase

Use Cases

• Low-threat periods requiring maximum performance
• Baseline network behavior profiling
• Troubleshooting connectivity issues
• Performance testing without QoS interference

Transition Logic

Score < 20:  Normal mode (observe only)
Score 20-49: Portal mode (light restrictions)
Score 50-79: Shield mode (moderate restrictions)
Score ≥80:   Lockdown mode (maximum restrictions)

3. Exception Blocking - Pre-Evaluation Defense

Denylist IP Blocking

• Purpose: Immediate blocking of known malicious IP addresses
• Configuration: Define IPs in soc.denylist_ips
• Response time: <50ms (bypasses AI evaluation)
• Implementation: nftables drop rules at prerouting chain
• Example:

  soc:
    denylist_ips:
      - "192.168.1.100"
      - "10.0.0.50"

Critical Signature Blocking

• Purpose: Pattern-based immediate blocking for high-severity threats
• Patterns: Configurable signature prefixes
• Default patterns:
  • ET EXPLOIT - Exploit attempts
  • ET MALWARE - Malware delivery
  • ET TROJAN - Trojan horse activity
  • Critical Infrastructure Attack - Infrastructure targeting
• Response time: <50ms
• Benefit: Saves 2-5 seconds by skipping Ollama evaluation for known-critical threats

4. Enhanced Traffic Control Engine

New Capabilities

• Immediate blocking: apply_block() method for nftables drop rules
• Idempotent operations: Safe to call multiple times without duplicates
• Complete cleanup: remove_rules_for_ip() removes all rule types (tc, nftables, block)
• Normal mode optimization: Automatic rule removal when entering normal mode

Rule Management

# Immediate block (exception blocking)
traffic_engine.apply_block(target_ip)

# Remove all rules (normal mode)
traffic_engine.remove_rules_for_ip(target_ip)

# Apply combined action (portal/shield/lockdown)
traffic_engine.apply_combined_action(target_ip, mode)

Release date: 2025-11-05

Highlights

Nginx reverse proxy for Mattermost: ready-to-use site config + setup script
One-shot Mattermost full reset script (DB + uploads), with Docker/Postgres support
Config schema extended to support multiple external interfaces
Suricata now monitors both wlan1 and eth0 by default
Documentation updated (EN/JA) with Nginx setup and network config notes
Added

deploy/nginx-site.conf: opinionated Nginx site for proxying Mattermost on http:/// to 127.0.0.1:8065
scripts/setup_nginx_mattermost.sh: installs Nginx, deploys the site config, enables and restarts the service
scripts/mattermost_reset.sh: destructive full reset (DB + uploads/plugins/logs)
Supports native systemd Mattermost and Docker/PostgreSQL deployments
Backs up /opt/mattermost to /var/backups before reset
Recreates Postgres DB or resets schema; handles SQLite; prints manual hints for MySQL
Changed

configs/azazel.schema.json: add interfaces.external (array) to explicitly mark WAN/uplink interfaces
configs/network/azazel.yaml: set default interfaces and add external: ["eth0","wlan1"]
deploy/suricata/suricata.yaml: monitor external interfaces wlan1 and eth0 (af-packet)
deploy/nginx.conf: add recommended proxy headers and client_max_body_size for Mattermost
README.md / README_ja.md: document Nginx reverse proxy setup and interface role defaults
pyproject.toml: bump version to 1.5.0
Breaking changes

None expected. The schema change is backward-compatible (interfaces.external is optional).
The sample config defaults changed (wlan0 as LAN, wlan1/eth0 as external); review if your environment differs.
Upgrade notes

Pull and update configs:
If you maintain local overrides of /etc/azazel/azazel.yaml, consider adding:
interfaces:
external: ["eth0", "wlan1"]
Suricata:
New default monitors eth0 as external. If eth0 is not present or undesired, adjust suricata.yaml accordingly.
Optional Nginx front for Mattermost:
Run as root: sudo setup_nginx_mattermost.sh
Access Mattermost at http:///
Add TLS via your own server block or Certbot if needed.
Optional: Mattermost full reset (destructive!):
Run: sudo bash mattermost_reset.sh and type RESET when prompted.
