Package: tinc
Version: 1.0.3-1
Severity: important
Tags: patch
In switch mode Tinc doesn't write received broadcasts to the local TUN/TAP
device. All broadcast packets are silently dropped. It makes ARP fail, which
makes the whole switch mode mostly unusable. I believe the bug affects hub
mode too.
Both versions 1.0.3-1 and 1.0.3-4 have this bug. The bug is fixed in the SVN
repository, from which I've created a patch that I included here. The patch
fixes the problems for me.
