With batman-adv 2020.4 and the according backports to batman-adv v2019.2 several more bugs were found and fixed regarding the batman-adv multicast optimizations feature. Also a "wakeup-call" feature was added to the Linux bridge IGMP/MLD snooping code in Gluon to work around issues with Android devices. With batman-adv now at v2019.2, multicast-to-multi-unicasts conversion is supported, too. Which means that even if there are a few outdated nodes these and all other recipients will be served multicast packets via unicast, too, as long as the sum of receiving nodes does not exceed the multicast fanout setting (default: 16). If is exceeded, then batman-adv will revert back to broadcast flooding automatically. Long story short, with all these extra measures in place, let's reenable the batman-adv multicast optimizations to reduce the layer 2 overhead and in preparation for multicast applications in the future. The default is enabled for this feature anyway, so removing the "batctl multicast_mode 0" overwrite is sufficient. Signed-off-by: Linus Lüssing <linus.luessing@c0d3.blue> |

Gluon's developers frequent an IRC chatroom at #gluon on hackint. There is also a webchat that allows for access from within your browser.
Issues & Feature requests
Before opening an issue, make sure to check whether any existing issues (open or closed) match. If you're suggesting a new feature, drop by on IRC or our mailinglist to discuss it first.
We maintain a Roadmap for the future development of Gluon.
Use a release!
Please refrain from using the master branch for anything else but development purposes!
Use the most recent release instead. You can list all releases by running git tag
and switch to one by running git checkout v2020.2.3 && make update.
If you're using the autoupdater, do not autoupdate nodes with anything but releases. If you upgrade using random master commits the nodes will break eventually.
