Hi Ben, some Debian/jessie systems were caught by the bug-report in [1]. This issue was recently fixed in an updated Debian kernel for v3.16.y.
Will you include the patch "tun: allow positive return values on dev_get_valid_name() call" [2] in linux-stable-3.16.y upstream? This was a fix for "tun: call dev_get_valid_name() before register_netdevice()" [3]. Unfortunately, there is not a reference (usually "Fixes:" tag) for this in [2]. Not sure if this was documented in the meantime like [4] says. Thanks in advance.
