Bugfixes
|
||
|
|
~~~~~~~~
|
||
|
|
|
||
|
|
* Remove broken DNS cache feature
|
||
|
|
(`#1362 <https://github.com/freifunk-gluon/gluon/issues/1362>`_)
|
||
|
|
|
||
|
|
It was found that dnsmasq does not handle all answer records
|
||
|
|
equally. In particular, its cached answers are missing DNSKEY and DS
|
||
|
|
records, breaking DNSSEC validation on clients.
|
||
|
|
|
||
|
|
Nodes can still resolve the next-node hostname locally and will continue to
|
||
|
|
work as DNS forwarders. The DNS cache feature may return if dnsmasq is fixed
|
||
|
|
or if we switch to a different resolver.
|
||
|
|
|
||
|
|
* Ensure that corefiles are stored in /tmp rather than cluttering the root
|
||
|
|
filesystem
|
||
|
|
(`00df8b76e54c <https://github.com/freifunk-gluon/gluon/commit/00df8b76e54c9bb89299df4b2ec49e972046d6b6>`_)
|
||
|
|
|
||
|
|
Nodes upgrades from Gluon v2016.2.x or earlier did not set kernel.core_pattern
|
||
|
|
correctly, leading to corefiles being stored in the current directory (usually
|
||
|
|
/ for system services) in the case of crashes.
|
||
|
|
|
||
|
|
This is a regression introduced in Gluon v2017.1.
|
||
|
|
|
||
|
|
* Only request a single IPv6 address instead of a prefix on the WAN interface
|
||
|
|
(`5db54ba78c3 <https://github.com/freifunk-gluon/gluon/commit/5db54ba78c3e245f06e4a407371608f6cb247b49>`_)
|
||
|
|
|
||
|
|
* Fix signal graph on status page when there are many neighbours
|
||
|
|

|
||
|
|
|
||
|
|
* Fix config files managed by opkg not being saved on sysupgrades on ar71xx-tiny
|
||
|
|
(LEDE/`17c0362178ca <https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=17c0362178caf837680a4631b8d0de94e5393448>`_,

|
||
|
|
|
||
|
|
* Fix kernel crash in batman-adv-14
|
||
|
|
(`#1358 <https://github.com/freifunk-gluon/gluon/issues/1358>`_)
|
||
|
|
|
||
|
|
Starting with Gluon v2017.1, respondd could trigger a kernel crash caused by
|
||
|
|
a use-after-free in batman-adv-14, in particular after a gateway disappeared.
|
||
|
|
|
||
|
|
batman-adv-15 is not affected.
|
||
|
|
|
||
|
|
* Increase bridge multicast querier timeout ("robustness") to avoid
|
||
|
|
"querier appeared/disappeared" log spam by batman-adv in the presence of
|
||
|
|
an external querier
|
||
|
|
(`e305a8c01917 <https://github.com/freifunk-gluon/gluon/commit/e305a8c019179472dbfc6fccea6c87cf40c08a75>`_)
|
||
|
|
|
||
|
|
* Fix "broken pipe" log spam caused by the status page
|
||
|
|
(`883c32f2f1dc <https://github.com/freifunk-gluon/gluon/commit/883c32f2f1dc368626069865c07a5701e3e9bcae>`_)
|
||
|
|
|

|
* Reduce memory limit of WLAN packet queues to 256KB on devices with small RAM
|
||
|
|
(`e63c6ca01f50 <https://github.com/freifunk-gluon/gluon/commit/e63c6ca01f50c96d76e5570faa290617a8a312b4>`_)
|
||
|
|
|
||
|
|
Will hopefully make out-of-memory crashes in busy meshes less likely.
|
||
|
|
|
||
|
|
* Improve image validation for TP-Link CPE/WBS 210/510 and make it ready for
|
||
|
|
future images
|
||
|
|
(LEDE/`6577fe2198f5 <https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=6577fe2198f5c75acb1dba789941d96a036f4dae>`_)
|
||
|
|
|
||
|
|
Future OpenWrt/Gluon images will move the image metadata ("support-list") of
|
||
|
|
the CPE/WBS 210/510 images to a different offset. Make sysupgrade ready
|
||
|
|
to allow installing such images.
|
||
|
|
|
||
|
|
This change was also backported to Gluon v2016.2.x to allow direct updates
|
||
|
|
to future Gluon master versions without installing v2017.1.x first.
|
||
|
|
|
||
|
|
* Sporadic segfaults of busybox (ash) when running shell scripts on ar71xx
|
||
|
|
have disappeared with the latest updates

|

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.
|
||
|
|
|
||
|
|
* Frequent reboots due to out-of-memory on weak hardware in larger meshes
|
||
|
|
