Under Linux 4.13 its not possible to configure GRE tunnel devices with a
MTU larger than 1500; this impacts on Open vSwitch (which creates tunnel
devices for
Simple reproducer:
sudo add-apt-repository cloud-archive:pike
sudo apt update
sudo apt install openvswitch-switch
sudo ovs-vsctl add-br br-tun
sudo ovs-vsctl add-port br-tun gre0 -- set interface gre0 type=gre
options:remote_ip=10.100.1.1
this will cause ovs to create the gre_sys device in the k

"Thanks Eric, that matches my findings, glad that there seems to be an
accepted fix already.
But it is fairly recent and only in since 4.15-rc8 levels afaik.
But OTOH its description at [1] reads pretty much like my notes so far.

Marking kernel tasks as confirmed as we have at least one related bug
which we have confirmed is fixed under 4.15 (and looks like an easy pick
for 4.13).

Thanks Greg
Joseph - would it be possible to get a 4.13 kernel prepared with the
patch identified picked?

Looking at the test history - artful passed tests with 4.11 and 4.12
kernels with 2.8.0, but appears to have started failing sporadically
when 4.13 entered the archive.

I don't have a data point for 4.11, but at 4.10 (as shipped in zesty)
ovs 2.8.1 tests are OK.

And some more testing:
xenial: ovs 2.8.1 + 4.4 - OK
xenial: ovs 2.8.1 + 4.10 - OK
so the issue appears to be the combination of ovs 2.8.1 (and 2.8.0) with
the 4.13 kernel.

And some more testing
xenial: ovs 2.5.2 + 4.4/4.10/4.13 - OK
xenial: ovs 2.8.1 + 4.13 - FAIL
so maybe this is something that ovs is doing that's breaking the kernel.
