[ovs-discuss] Small 802.1q-prepended packets not getting through to VM

Hi,

I have an appliance VM (Cisco vWLC) in libvirt/KVM, connected to an Open
vSwitch bridge through a virtio NIC. For untagged packets, this works fine.
However, the appliance also has a VLAN (I've numbered it 50), tagged using
802.1q. I've attached this to an EoGRE tunnel (tag=50, access port) to
a remote Linux machine (not running Open vSwitch) to reach out to it.

The VM can _send_ packets on this VLAN just fine, and also receive large
packets. However, packets under 60 bytes, such as ARP packets, don't appear
to reach the VM at all. If I attach an OVS internal port, I can see them just
fine on tcpdump, but crucially, they don't have any Ethernet padding, so they
are below the allowed minimum size. (The packets _from_ the VM have Ethernet
padding just fine.)

I get the same result by trying to talk to the VM on the OVS internal port;
ARP packets and small ping packets (ping -s 13 and below, ie. 59 bytes or
less) don't appear to go through to the VM, but larger packets (ping -s 14
and above) work just fine. However, the OVS internal port can reach the EoGRE
host just fine, on all packet sizes.

Is there anything I can do about this? It appears to just be a bug to me.
I'm running Debian buster (kernel 4.19.0-5-amd64, Open vSwitch 2.10.1);
earlier, I've been running Debian stretch (kernel 4.9.0, Open vSwitch 2.6.2)
with no difference in behavior.

I'm attaching conf.db.
