Gluon 2017.1.2

New features

  • Preserve gw_mode on sysupgrades (#1196)

    When a Gluon node is used as uplink (for example by connecting it to a router with a DHCP server directly, instead of using non-Gluon servers for the internet uplink), the gw_mode must be set to server on that node. The changed gw_mode is now preserved on upgrades.

  • Allow configuring the batman-adv routing algorithm (BATMAN IV or BATMAN V) in site.conf (#1185)

    BATMAN V still hasn’t received extensive testing (and is incompatible with BATMAN IV). This new option allows to set up BATMAN V-based test meshes. If unset, the routing algorithm will default to BATMAN IV.


    mesh = {
      batman_adv = {
        routing_algo = 'BATMAN_V'
  • New show-release Make target

    The command make show-release can be used to print the release number defined by GLUON_RELEASE to the standard output. This can be useful for build scripts when a $(shell ...) expression is used in to generate the release number.


  • The image build code used for some devices has been fixed, solving multiple issues (#1193)

    Problems caused by this issue include:

    • sysupgrade rejecting Allnet images
    • OpenMesh devices losing their configuration on upgrades

    This is a regression introduced in Gluon v2017.1.

  • Improve sysupgrade error handling (#1160)

    If for some reason processes don’t react to SIGKILL (usually because of a kernel bug), a node could hang forever in sysupgrade, requiring a power cycle. This has been fixed, triggering a reboot instead.

  • Also display gluon-config-mode:novpn message when Tunneldigger is installed, but disabled (#1172)

    It was only displayed on nodes with fastd before.

  • Fix migration of enabled/disabled state between fastd and Tunneldigger (#1187)

Known issues

  • 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.

  • 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 promicious mode is disallowed).

  • Inconsistent respondd API (#522)

    The current API is inconsistent and will be replaced eventually. The old API will still be supported for a while.

  • Sporadic segfaults of busybox (ash) when running shell scripts on ar71xx (#1157)

    The workaround added in Gluon v2017.1.1 has greatly reduced the frequency of segfaults, but did not make them disappear completely.
