Atheros target migration

All Atheros MIPS devices built with the ar71xx-generic, ar71xx-nand as well as ar71xx-tiny were deprecated upstream and are therefore not available with Gluon anymore.

Many devices previously built with ar71xx-generic and ar71xx-nand are now available with the ath79-generic as well as ath79-nand target respectively.

Features

WireGuard

Gluon got WireGuard support. This allows offloading encrypted connections into kernel space, increasing performance by forwarding packets without the need for context switches between user and kernel space.

In order to reuse existing (already verified) fastd-keypairs for WireGuard, a key derivation procedure is currently being developed. This should ease migration from fastd to WireGuard in case whitelisting VPN keys is desired.

fastd L2TP

fastd can now act as a connection broker for unencrypted L2TP-based tunneling within Gluons mesh-vpn framework. This new null@l2tp connection method allows for increased performance within existing fastd setups.

In addition to a sufficiently :ref:`configured fastd-based VPN server<vpn-gateway-configuration>`, this requires further modifications to a sites :ref:`VPN fastd methods<VPN fastd methods>`.

Major changes

OpenWrt

This release is based on the newest OpenWrt 22.03 release branch. It ships with Linux kernel 5.10 as well as wireless-backports 5.15.

Network changes (DSA / Upgrade-Behavior)

The ramips-mt7621 and lantiq-xrx200 targets now use the upstream DSA subsystem instead of OpenWrt swconfig for managing ethernet switches.

Gluon detects the existing user-intent and automatically applies it over to DSA syntax. See the section about network reconfiguration for more details.

System reconfiguration

The network and system-LED configurations are now re-generated after each update / invocation of gluon-reconfigure.

The user-intent is preserved within Gluon’s implemented functionality (Wired-Mesh / Client access / WAN).

As an additional feature, Gluon now supports assigning roles to interfaces. This behavior is explained :ref:`here<wired-mesh-commandline>`.

Site changes

VPN provider MTU

To account for multiple VPN methods available for a site, the MTU used for the VPN tunnel connection is now moved to the specific VPN provider configuration. For fastd this means that mesh_vpn.mtu needs to be moved to mesh_vpn.fastd.mtu. (#2352)

Preconfigured Interfaces Roles

Instead of mesh_on_wan and mesh_on_lan there is now an interfaces block to configure the default behavior of network interfaces. Details can be found in the :ref:`documentation<user-site-interfaces>`.

Minor changes

• The brcm2708-bcm2708 brcm2708-bcm2709 brcm2708-bcm2710 targets were renamed to bcm27xx-bcm2708 bcm27xx-bcm2709 and bcm27xx-bcm2710
• The GL.iNet GL-AR750S was moved to the ath79-nand subtarget
• Gluon now ships the ath10k-ct firmware derivation for QCA9886 / QCA9888 / QCA9896 / QCA9898 / QCA9984 / QCA9994 / IPQ4018 / IPQ4028 / IPQ4019 / IPQ4029 radios (#2541)
• WolfSSL instead of OpenSSL is now used when built with WPA3 support
• The option to configure the wireless-channel independent from the site-selected channel was moved from gluon-core.wireless.preserve_channels to gluon.wireless.preserve_channels
• gluon-info is a new command that provides information about the current node
• GLUON_DEPRECATED is now set to 0 by default
• To reboot a running gluon-node into setup-mode, Gluon now offers the gluon-enter-setup-mode command
• Devices without WLAN do not show the private-wifi configuration anymore
• The Autoupdater now uses the site default branch in case it is configured to use a non-existent / invalid branch

Known issues

• A workaround for Android devices not waking up to their MLD subscriptions was removed, potentially breaking IPv6 connectivity for these devices after extended sleep periods. (#2672)

• Upgrading EdgeRouter-X from versions before v2020.1.x may lead to a soft-bricked state due to bad blocks on the NAND flash which the NAND driver before this release does not handle well. (#1937)

• The integration of the BATMAN_V routing algorithm is incomplete.

  • Mesh neighbors don't appear on the status page. (#1726) Many tools have the BATMAN_IV metric hardcoded, these need to be updated to account for the new throughput metric.
  • Throughput values are not correctly acquired for different interface types. (#1728) This affects virtual interface types like bridges and VXLAN.

• Default TX power on many Ubiquiti devices is too high, correct offsets are unknown (#94)

  Reducing the TX power in the Advanced Settings is recommended.

• In configurations without VXLAN, the MAC address of the WAN interface is modified even when Mesh-on-WAN is disabled (#496)

  This may lead to issues in environments where a fixed MAC address is expected (like VMware when promiscuous mode is disallowed).
