Jan 1, 2026

January 2026 delivered measurable business value through stability improvements, robust configuration management, and radio-aware behaviors across two core OpenWrt deployments. Key outcomes include stabilizing dual-boot certificate handling in wlan-ap to prevent duplicate operational certificates and preserve birth certs, enabling dynamic configuration reloads via UCI overlays, and fixing upgrade script syntax on ipq53xx to ensure reliable upgrades. In addition, QoS and schema improvements were introduced on Mediatek and core components to improve performance and reliability: switching to SFQ on Mediatek targets, and enriching the ucentral schema for band-aware SSID naming, reconf derivation from radio capabilities, and safe handling of null device statistics. Collectively, these changes reduce upgrade risk, improve deployment reliability, and enable more accurate, scalable WLAN management.

Nov 1, 2025

November 2025 monthly summary for Telecominfraproject/wlan-ap: Focused on reliable, secure automatic discovery, enrollment, and certificate management to enable scalable, zero-touch deployments in both centralized and air-gapped environments. Key outcomes include: - EST/DNS discovery enhancements: Implemented CAA DNS-based EST server discovery and switched to dig-based CAA lookups with enhanced debug logging; supports controller FQDNs from cloud.json and robust fallback logic. - Zero-touch provisioning and discovery sequencing: Added standard FQDN fallback discovery (configured via STANDARD_FQDN, default openwifi.network) and revised discovery order to prioritize EST enrollment, DHCP discovery, flash-based config, then FQDN resolution, enabling automatic controller discovery in DNS-only environments. - Certificate management for air-gapped deployments: Bootstrapping improvements to copy all certificates at startup; per-controller certificate naming with FQDN-based files; added certificate path configuration in gateway.json and /tmp/discovery.method to guide est_client; enhanced mTLS for EST and updated to latest ucentral-client for certificate handling. - FQDN security hardening: Adopted local .local TLD for standard FQDN discovery (openwifi.wlan.local) to mitigate DNS hijacking risks. - Security and reliability improvements: Added DNS rebind allowances for controller FQDNs in air-gapped deployments, and opened OpenLAN CA-based certificate support for secure enrollment. Major bug fix: - LED Board Configuration Bug Fix for Mediatek: Fixed a missing case terminator in LED board config to prevent fall-through (commit f6dbae786661a707d7816ea380c850d6981ee0d2). This work reduces manual configuration, speeds onboarding of devices, and strengthens security across centralized and air-gapped networks.
