Gluon 2019.1.2
##############
Bugfixes
********
* Fixes a buffer-overflow vulnerability in libubox, a core component of OpenWrt
(CVE-2020-7248)
* Fixes a vulnerability in the OpenWrt package manager (opkg). By using this vulnerability,
an attacker could bypass the integrity check of the package artifacts. (CVE-2020-7982)
Other Changes
*************
* Linux kernel has been updated to either
- 4.9.211 (ar71xx, brcm2708, mpc85xx) or
- 4.14.167 (ipq40xx, ipq806x, mvebu, ramips, sunxi, x86).
Known issues
************
* Out of memory situations with high client count on ath9k.
(`#1768 <https://github.com/freifunk-gluon/gluon/issues/1768>`_)
* The integration of the BATMAN_V routing algorithm is incomplete.
- Mesh neighbors don't appear on the status page. (`#1726 <https://github.com/freifunk-gluon/gluon/issues/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 <https://github.com/freifunk-gluon/gluon/issues/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 <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 promiscuous 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 or high load due to memory pressure on weak hardware especially in larger
meshes (`#1243 <https://github.com/freifunk-gluon/gluon/issues/1243>`_)
Optimizations in Gluon 2018.1 have significantly improved memory usage.
There are still known bugs leading to unreasonably high load that we hope to
solve in future releases.
