arjunbaindurhello, seeing severe issue with https://bugs.launchpad.net/neutron/+bug/1732067 or https://bugs.launchpad.net/neutron/+bug/186644501:24
openstackLaunchpad bug 1732067 in OpenStack Security Notes "openvswitch firewall flows cause flooding on integration bridge" [Undecided,New]01:24
openstackLaunchpad bug 1866445 in neutron "br-int bridge in one compute can't learn MAC addresses of VMs in other compute nodes" [Medium,In progress] - Assigned to Li YaJie (yjmango)01:24
arjunbaindurlatter is committed, the second, we pulled ourselves to test since its for iptables firewall01:24
arjunbaindurIt breaks MAC learning for local ports on provider networks. So flooding happend in opposite direction - ingress packets into hosts destined to a local VM, are flooding on all over qvo ports01:25

fricklerslaweq: ovn is failing on focal because the kernel is too new, are there plans to use distro pkgs for ovn there? https://2c8e3c862a01a326d3cf-e7631c5842b30279943de651c580e67f.ssl.cf1.rackcdn.com/737370/1/check/neutron-ovn-tempest-ovs-release/82adbe2/job-output.txt07:42
slaweqfrickler: yes, we are compiling ovn from source on bionic just because packaged version don't have some features needed for QoS07:43
slaweqbut on focal we can use version from distro package07:44
slaweqmaciejjozefczyk: is that correct ^^ ?07:44
maciejjozefczykslaweq, yes, we can disable compilation on focal07:45

arjunbaindurslaweq, any thoughts about https://bugs.launchpad.net/neutron/+bug/1884708 if you get some time?07:51
openstackLaunchpad bug 1884708 in neutron "explicity_egress_direction prevents learning of local MACs and causes flooding of ingress packets" [Undecided,New]07:51
arjunbaindurwe are testing out the fix for https://bugs.launchpad.net/neutron/+bug/1732067 (and it's sister fix, for iptables), and seeing a worse flooding issue07:52

*** jpena|off is now known as jpena07:54
arjunbainduram i correct in assuming that the table=60 direct output action on ingress will only be hit for tunnel networks? VLAN networks continue to hit the NORMAL action. for provider network, there are no explicit table 60 output rules, and for VLAN tenant network attached to a DVR router, the dl_vlan in the rule is the external VLAN. But the vlan has already been translated to local vlan for a L2 packet.07:55
arjunbaindurThis is not the case for an inbound tunnel packet07:57
arjunbaindurSO basically the fix for 1732067 / 1866445 seems to fix egress flooding for tunnel networks. But it causes ingress flooding for VLAN networks.07:58
