Package: src:linux Version: 3.14.2-1 Severity: important Dear Maintainer,
Since 3.14-rc8, an upstream bug has caused a serious regression in tun performance, affecting for example users op OpenVPN. The bug causes extremely slow transfer speeds/session freezes for traffic usinG tun devices. The bug was fixed in 3.15-rc, however not in 3.14 (yet). To reproduce: - Configure a client/server VPN using OpenVPN (use 'dev tun') - Start the VPN connection - Start a SSH session over the VPN tunnel - Type some commands causing a fair amount of output (like 'dmesg' a couple of times) - Watch the output slow down or even stall Upstream bug reports: https://bugzilla.kernel.org/show_bug.cgi?id=73891 https://bugzilla.kernel.org/show_bug.cgi?id=74051 Patch: http://www.spinics.net/lists/netdev/msg279297.html https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=1e785f48d29a09b6cf96db7b49b6320dada332e1 Please consider including this patch.
