Gluon 2017.1
|
||||
============
|
||||
|
||||
General changes
|
||||
~~~~~~~~~~~~~~~
|
||||
|
||||
Gluon 2017.1 is the first release of Gluon based on the LEDE 17.01 branch. The
|
||||
kernel has been updated from 3.18.x to 4.4.x.
|
||||
|
||||
We've used the opportunity to greatly simplify the Gluon build system, removing
|
||||
many hacks that were required to make the build work with older OpenWrt releases.
|
||||
|
||||
The *output/modules* directory is now called *output/packages* and provides a
|
||||
replacement for the whole repository with target-specific packages of LEDE (in
|
||||
contrast to packages that are common for all targets of the same architecture).
|
||||
|
||||
**Note: There is an issue in all Gluon versions before 2016.2.6 that will
|
||||
lead to x86 systems losing their configuration when upgrading to Gluon 2017.1!**
|
||||
Older Gluon versions should be upgraded to 2016.2.6 first before switching to
|
||||
2017.1.
|
||||
|
||||
Added hardware support
|
||||
~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
ar71xx-generic
|
||||
^^^^^^^^^^^^^^
|
||||
|
||||
* TP-Link
|
||||
|
||||
- RE450
|
||||
- WBS210 v1.20
|
||||
- WBS510 v1.20
|
||||
|
||||
* Ubiquiti
|
||||
|
||||
- AirGateway LR
|
||||
- AirGateway PRO
|
||||
- Rocket M2/M5 Ti
|
||||
- UniFi AP LR
|
||||
|
||||
ar71xx-tiny
|
||||
^^^^^^^^^^^
|
||||
|
||||
The new *ar71xx-tiny* target has split out of *ar71xx-generic*; all
|
||||
*ar71xx-generic* devices with only 4MB of flash have been moved to this target.
|
||||
|
||||
In contrast to *ar71xx-generic*, *ar71xx-tiny* **does not support opkg anymore**
|
||||
to save some space.
|
||||
|
||||
* TP-Link
|
||||
|
||||
- TL-WA730RE v1
|
||||
- TL-WA7210N v2
|
||||
|
||||
x86-generic
|
||||
^^^^^^^^^^^
|
||||
|
||||
The *x86-kvm* and *x86-xen_domu* targets have been removed; the *x86-generic*
|
||||
images now support these usecases as well, so no separate targets are needed
|
||||
anymore.
|
||||
|
||||
x86-geode
|
||||
^^^^^^^^^
|
||||
|
||||
The new *x86-geode* target for hardware based on Geode CPUs has been added.
|
||||
|
||||
New features
|
||||
~~~~~~~~~~~~
|
||||
|
||||
* Localization support has been added to the status page. In addition to German,
|
||||
there are English and Russian translations now (`#1044 <https://github.com/freifunk-gluon/gluon/issues/1044>`_)
|
||||
|
||||
* Add support for making nodes a DNS cache for clients
|
||||
(`#1000 <https://github.com/freifunk-gluon/gluon/issues/1000>`_)
|
||||
|
||||
See also: :doc:`../features/dns-cache`
|
||||
|
||||
* Add L2TP via tunneldigger as an alternative VPN system
|
||||
(`#978 <https://github.com/freifunk-gluon/gluon/issues/978>`_)
|
||||
|
||||
L2TP will usually give better performance than fastd as it runs in kernel
|
||||
space, but it does not provide encryption.
|
||||
|
||||
It is not possible to include both fastd and tunneldigger in the same
|
||||
firmware.
|
||||
|
||||
* Add source filter package (`#1015 <https://github.com/freifunk-gluon/gluon/issues/1015>`_)
|
||||
|
||||
The new package *gluon-ebtables-source-filter* can be used to prevent traffic
|
||||
using unexpected IP addresses or packet types from entering the mesh.
|
||||
|
||||
See also: :doc:`../package/gluon-ebtables-source-filter`
|
||||
|
||||
Bugfixes
|
||||
~~~~~~~~
|
||||
|
||||
* Disabling batman-adv on an interface (for example when an Ethernet link is lost
|
||||
or before sysupgrades) could lead to a kernel crash in certain configurations
|
||||
(`#680 <https://github.com/freifunk-gluon/gluon/issues/680>`_)
|
||||
|
||||
* A race condition in the network setup scripts could lead to incomplete setup
|
||||
during boot or when interfaces were added or removed from batman-adv after
|
||||
Ethernet link changes (`#905 <https://github.com/freifunk-gluon/gluon/issues/905>`_)
|
||||
|
||||
The fix also solved the long-standing issue of Ethernet-only nodes (i.e. no
|
||||
WLAN or VPN mesh) not booting up correctly without an Ethernet mesh link.
|
||||
|
||||
* Some fixes in the WLAN stack of LEDE have improved the stability of the ath9k
|
||||
driver (`#605 <https://github.com/freifunk-gluon/gluon/issues/605>`_)
|
||||
|
||||
Site changes
|
||||
~~~~~~~~~~~~
|
||||
|
||||
site.mk
|
||||
^^^^^^^
|
||||
|
||||
* The *gluon-legacy* package does not exist anymore
|
||||
* All *gluon-luci-* packages have been renamed to *gluon-web-*
|
||||
* The *gluon-next-node* package has been merged into the Gluon core and must not
|
||||
be specified in *site.mk* anymore
|
||||
|
||||
site.conf
|
||||
^^^^^^^^^
|
||||
|
||||
* The *fastd_mesh_vpn* configuration section has been restructured to allow
|
||||
sharing more options with tunneldigger. Instead of
|
||||
|
||||
.. code-block:: lua
|
||||
|
||||
fastd_mesh_vpn = {
|
||||
mtu = 1280,
|
||||
configurable = true,
|
||||
methods = {'salsa2012+umac'},
|
||||
groups = { ... },
|
||||
bandwidth_limit = { ... },
|
||||
}
|
||||
|
||||
the configuration must look like this now:
|
||||
|
||||
.. code-block:: lua
|
||||
|
||||
mesh_vpn = {
|
||||
mtu = 1280,
|
||||
fastd = {
|
||||
configurable = true,
|
||||
methods = {'salsa2012+umac'},
|
||||
groups = { ... },
|
||||
}
|
||||
bandwidth_limit = { ... },
|
||||
}
|
||||
|
||||
* The *opkg.openwrt* option has been renamed to *opkg.lede*
|
||||
|
||||
i18n
|
||||
^^^^
|
||||
|
||||
* The *escape* function has been removed as it was duplicating the existing
|
||||
*pcdata* function. All uses of *escape* in i18n templates must be changed to
|
||||
use *pcdata* instead.
|
||||
|
||||
* The *gluon-config-mode:altitude-label* and *gluon-config-mode:altitude-help*
|
||||
translation IDs have been added to allow adjusting the texts for different
|
||||
kinds of altitudes that might be expected.
|
||||
|
||||
* The optional *gluon-config-mode:novpn* label has been added, which will be
|
||||
shown in place of *gluon-config-mode:pubkey* when mesh VPN is disabled.
|
||||
|
||||
Internals
|
||||
~~~~~~~~~
|
||||
|
||||
* The LuCI base libraries have been replaced by a stripped-down
|
||||
version called "gluon-web" (`#1007 <https://github.com/freifunk-gluon/gluon/issues/1007>`_)
|
||||
|
||||
Custom packages will need to be adjusted; in particular, all uses of *luci.model.uci*
|
||||
need to be replaced with *simple-uci*. The Gluon documentation explains the most important
|
||||
changes required to migrate from LuCI to gluon-web.
|
||||
|
||||
* respondd now listens on ``ff05::2:1001`` in addition to ``ff02::2:1001`` for mesh-wide
|
||||
operation (`#984 <https://github.com/freifunk-gluon/gluon/issues/984>`_)
|
||||
|
||||
Eventually, ``ff02::2:1001`` will be available for exchanging information
|
||||
between neighbouring nodes only; map servers should be moved to ``ff05::2:1001``.
|
||||
|
||||
* batman-adv has been updated to version 2017.1
|
||||
|
||||
* Directly running make commands in the *lede* directory is supported now. Consequently,
|
||||
build targets like ``target/linux/clean`` and ``package/NAME/compile`` can't be used
|
||||
in the Gluon repository root anymore.
|
||||
|
||||
The command ``make config`` will set up the LEDE *.config* in the way a normal
|
||||
Gluon build would, so it's possible to build individual packages for testing
|
||||
and development afterwards.
|
||||
|
||||
* Target definitions have been migrated from a Make-based format to a simpler
|
||||
Shell-based DSL
|
||||
|
||||
Known issues
|
||||
~~~~~~~~~~~~
|
||||
|
||||
* Default TX power on many Ubiquiti devices is too high, correct offsets are unknown (`#94 <https://github.com/freifunk-gluon/gluon/issues/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 <https://github.com/freifunk-gluon/gluon/issues/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 <https://github.com/freifunk-gluon/gluon/issues/522>`_)
|
||||
|
||||
The current API is inconsistent and will be replaced eventually. The old API will still be supported for a while.
