- x86-xen_domu
- ^^^^^^^^^^^^
- New target containing the necessary drivers for use in Xen.
- x86-64
- ^^^^^^
- 64bit version of `x86-generic`. The generic image can also be used in KVM with VirtIO.
- New features
- ~~~~~~~~~~~~
- Kernel module opkg repository
- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
- We've not been able to keep ABI compatiblity with the kernel of the official OpenWrt images.
- Therefore, Gluon now generates an opkg repository with modules itself.
- The repository can be found at `output/modules/` by default, the image output directory has
- been moved from `images/` to `output/images/`. See the updated :doc:`../user/getting_started` guide
- for information on the handling of the signing keys for this repository.
- The `opkg_repo` site.conf option has been replaced to allow specifying this and other additional repositories.
- New status page
- ^^^^^^^^^^^^^^^
- The new status page provides a visually pleasing experience, and displays all important information
- on a node in a clear manner. It also contains a real-time signal strength graph for all neighbouring
- nodes to aid with the alignment of antennas.
- 802.11s mesh support
- ^^^^^^^^^^^^^^^^^^^^
- Gluon now supports using 802.11s for its mesh links instead of IBSS (Adhoc). This will allow supporting
- more WLAN hardware in the future (like Ralink/Mediatek, which don't support AP and IBSS mode simultaneously).
- Note that batman-adv is still used on top of 802.11s (and 802.11s forwarding is disabled), the mesh routing protocol
- provided by 802.11s is not used.
- Multicast filter extension
- ^^^^^^^^^^^^^^^^^^^^^^^^^^
- The `gluon-ebtables-filter-multicast` package has been extended to filter out multicast
- ICMP and ICMPv6 Echo Requests (ping) and Node Information Queries (RFC4620). This prevents
- pings to multicast addresses like ff02::1 to cause traffic peaks
- (as all nodes and clients would answer such a ping).
- French translation
- ^^^^^^^^^^^^^^^^^^
- A French translation for the Config Mode/Expert Mode has been added.
- Bugfixes
- ~~~~~~~~
- * Update kernel code for the QCA953x
- Might improve stability of the TP-Link TL-WR841N/ND v9.
- * Fix model detection on some Netgear WNDR3700v2
- The broken devices will identify as "NETGEAR ".
- This also breaks the autoupdater, making a manual upgrade necessary.
- * Ensure that `odhcp6c` doesn't spawn multiple instances of ``dhcpv6.script``
- * Fix support for Buffalo WZR-600DHP
- A flashable factory image is generated now. The sysupgrade image is still shared
- with the WZR-HP-AG300H.
- Site changes
- ~~~~~~~~~~~~
- * ``site.conf``
- - New WLAN configuration
- ``wifi24`` and ``wifi5`` need to be updated to a new more flexible format.
- A configuration using the old format
- ::
- {
- channel = 1,
- htmode = 'HT20'
- ssid = 'entenhausen.freifunk.net',
- mesh_ssid = 'xe:xx:xx:xx:xx:xx',
- mesh_bssid = 'xe:xx:xx:xx:xx:xx',
- mesh_mcast_rate = 12000,
- }
- would look like this in the new format::
- {
- channel = 1,
- ap = {
- ssid = 'entenhausen.freifunk.net',
- },
- ibss = {
- ssid = 'xe:xx:xx:xx:xx:xx',
- bssid = 'xe:xx:xx:xx:xx:xx',
- mcast_rate = 12000,
- },
- }
- The ``htmode`` option has been dropped, the channel width is now always set to 20MHz
- (see https://github.com/freifunk-gluon/gluon/issues/487 for a discussion of this change).
- In addition to the old IBSS (Adhoc) based meshing, 802.11s-based meshing can be configured
- using the ``mesh`` section. Example::
- {
- channel = 1,
- ap = {
- ssid = 'entenhausen.freifunk.net',
- },
- mesh = {
- id = 'mesh.entenhausen.freifunk.net', -- can by any string, human-readable or random
- mcast_rate = 12000,
- },
- }
- While using ``ibss`` and ``mesh`` at the same time is possible, is causes high load in
- very active meshes, so it is advisable to avoid such configurations.
- - Bandwidth limitation defaults
- The old section ``simple_tc.mesh_vpn`` has been moved to ``fastd_mesh_vpn.bandwidth_limit`` and the ``ifname``
- field isn't used anymore. What looked like this
- before
- ::
- simple_tc = {
- mesh_vpn = {
- ifname = 'mesh-vpn',
- enabled = false,
- limit_ingress = 3000,
- limit_egress = 200,
- }
- }
- needs to be changed to
- ::
- fastd_mesh_vpn = {
- -- ...
- bandwidth_limit = {
- enabled = false,
- ingress = 3000,
- egress = 200,
- },
- }
- - opkg repository configuration
- The opkg configuration has been changed to be more flexible and allow specifying custom repositories.
- Example::
- opkg = {
- openwrt = 'http://opkg.services.ffeh/openwrt/%n/%v/%S/packages',
- extra = {
- modules = 'http://opkg.services.ffeh/modules/gluon-%GS-%GR/%S',
- },
- }
- The keys of the ``extra`` table (like ``modules`` in this example) can be chosen arbitrarily.
- Instead of explicitly specifying the whole URL, using patterns is recommended. The following
- patterns are understood:
- - ``%n`` is replaced by the OpenWrt version codename (e.g. "chaos_calmer")
- - ``%v`` is replaced by the OpenWrt version number (e.g. "15.05")
- - ``%S`` is replaced by the target architecture (e.g. "ar71xx/generic")
- - ``%GS`` is replaced by the Gluon site code (as specified in ``site.conf``)
- - ``%GV`` is replaced by the Gluon version
- - ``%GR`` is replaced by the Gluon release (as specified in ``site.mk``)
- * ``site.mk``
- - The packages `gluon-announce` and `gluon-announced` were merged into
- the package `gluon-respondd`. If you had any of them (probably
- `gluon-announced`) in your package list, you have to replace them.
- * ``i18n/``
- - The translations of ``gluon-config-mode:pubkey`` now have to show the fastd
- public key themselves if desired, making the formatting of the key and whether it is shown at
- all configurable. To retain the old format, add ``<p>`` to the beginning of
- your translations and append::
- "</p>"
- "<div class=\"the-key\">"
- " # <%= hostname %>"
- " <br/>"
- "<%= pubkey %>"
- "</div>"
- Internals
- ~~~~~~~~~
- * OpenWrt has been updated to Chaos Calmer
- * mac80211 has been backported from OpenWrt trunk r47249 (wireless-testing 2015-07-21)
- This allows us to support the TL-WR940N v3/TL-WR941ND v6, which uses a TP9343 (QCA956x) SoC.
- * Several packages have been moved from the Gluon repo to the packages repo, removing references to Gluon:
- - gluon-cron -> micrond (the crontabs are now read from ``/usr/lib/micron.d`` instead of ``/lib/gluon/cron``)
- - gluon-radvd -> uradvd
- - gluon-simple-tc -> simple-tc (the config file has been renamed as well)
- * Some of the Gluon-specific i18n support code in the build system has been removed, as LuCI now provides
- similar facilities
- * The C-based `luci-lib-jsonc` library is now used for JSON encoding/decoding instead of the pure Lua `luci-lib-json`
- * The site config is now stored as JSON on the node. The Lua interface ``gluon.site_config`` is still available, and a C interface was added as part of the new package `libgluonutil`.
- * The `respondd` daemon now uses C modules instead of Lua snippets, which greatly enhances response speed and reduces memory usage. The Gluon integration package has
- been renamed from `gluon-announced` to `gluon-respondd`.
- 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 Expert Mode is recommended.
- * batman-adv causes stability issues for both alfred and respondd/announced (`#177 <https://github.com/freifunk-gluon/gluon/issues/177>`_)
- * 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/announced API (`#522 <https://github.com/freifunk-gluon/gluon/issues/522>`_)
- The current API is inconsistent and will be replaced in the next release. The old API will still be supported for a while.
