opendevreviewSlawek Kaplonski proposed openstack/neutron master: Don't prevent setting CIDRs as allowed_address_pair for port  https://review.opendev.org/c/openstack/neutron/+/96864606:37
opendevreviewRodolfo Alonso proposed openstack/neutron master: [OVN] Add 'provider:physical_network' field if there is physnet  https://review.opendev.org/c/openstack/neutron/+/96876908:52
mnasiadkaralonsoh: Do you have an idea if there’s a version of https://bugzilla.redhat.com/show_bug.cgi?id=2238969 that has been created in the new Jira tracker?09:23
ralonsohlet me check09:24
ralonsohmnasiadka, that was reported in https://bugs.launchpad.net/neutron/+bug/2032817 too09:27
ralonsohand fixed here:09:27

ralonsoh(since 2025.1)09:27
mnasiadkaralonsoh: well, the check_pkt_len stuff in OVS/OVN is not fixing that completely, some of my customers are seeing very low bandwidth when using 9k Geneve internal MTU and regular 1500 on outside - so I’ll probably do some analysis and fire off a ticket to FDP09:45
mnasiadkaI understand it’s not Neutron’s fault, just wanted to follow up on something - but I see I need to create a new FDP ticket09:46
ralonsohmnasiadka, don't you have a case open?09:46
mnasiadkaralonsoh: well, I’m not an RH customer :) so most probably it should be an email to ovs-discuss :)09:47
opendevreviewTobias Urdin proposed openstack/neutron master: Cleanup stale DHCP ports not bound to host  https://review.opendev.org/c/openstack/neutron/+/96877009:49
ralonsohmnasiadka, do you have the flag ovn_emit_need_to_frag=True?09:49
mnasiadkaralonsoh: yes09:53
mnasiadkaWithout that it’s even worse :)09:53
ralonsohso then there is fragmentation but at a cost09:54
ralonsohmaybe that could be improved (somehow) by OVS folks09:54
mnasiadkaI’ll run some tcpdumps to see why the bandwidth is so low - like kilobytes per second on a 10G link09:56
opendevreviewDr. Jens Harbott proposed openstack/neutron master: Don't prevent setting CIDRs as allowed_address_pair for port  https://review.opendev.org/c/openstack/neutron/+/96864610:37
fricklerah, the MTU stuff. I think this was only partially fixed indeed10:51
fricklerdownstream we also use 1500 on the inside for everything because of that10:52
mnasiadkafrickler: HPC land doesn’t like 1500 ;-)11:02
fricklerat the risk of going offtopic: is the delta really still as important as it was 20 years ago? also, can you do different tenant networks, then?11:04
mnasiadkaI don’t know, but surely there is something to it - if it is still THAT important - I have no clue11:15
ralonsohbcafarel, hello! some trivial backports: https://review.opendev.org/q/topic:%22bug/2132982%22. Thanks in advance11:22
*** srelf__ is now known as continuity11:31
mnasiadkafrickler: actually I found https://lore.kernel.org/all/20240516200941.16152-1-aconole@redhat.com/ which is only in RHEL 9.7 (when you use EL or clones) - don’t know if that is in Ubuntu-land in some recent kernel11:37
fricklermnasiadka: interesting patch, looks pretty simple for such a kind of problem. but also this is only for OVS, not for OVN, right? it talks about L3 tunnels, but that's likely different from OVNs gateway functionality?12:13
mnasiadkafrickler:  well this is openvswitch kmod, ovn programs flows in ovs - so it’s probably related12:21
mnasiadkafrickler: I’ll try out Rocky 9.7 when it’s out in coming weeks to see if that gets better12:22
opendevreviewRodolfo Alonso proposed openstack/neutron master: [OVN] Add documentation/reno for the OVN external port N/S routing  https://review.opendev.org/c/openstack/neutron/+/96879713:58

slaweqralonsoh: ^^ here is docs patch which we were talking about earlier this week15:02
ralonsohslaweq, thanks!15:02
ralonsohslaweq, btw, about https://review.opendev.org/c/openstack/neutron/+/968646 (that is almost merged)15:03
ralonsohchecking https://review.opendev.org/q/I9b54e12fbd9b930a79660f2be195641107a5754e15:03
ralonsohwe'll need backports up to 2024.215:03
ralonsohjust a heads-up15:03
