mdormanwe are seeing an issue where neutron-server iterates over all security groups in all tenants during certain operations, with 1 select query each.  we have ~1000 tenants with 10 secgroups each, so when this happens neutron-server is tanked for several minutes.00:16
mdormantrying to run down where that might be happning in the code.  i've been able to gather the few sql calls up to when it starts.  http://pastebin.com/ZkP5idkJ00:17
mdormanand those select calls at hte bottom continue, one for each of the 10k security groups.00:17

*** Jabadia has quit IRC11:20
obondarevamotoki: I'd like to discuss lbaas renamings patch: https://review.openstack.org/#/c/61339 Do you have some time for this?11:20
amotokiobondarev: sure11:21
obondarevamotoki: the structure that you've proposed definitely makes sense. However I have a concern that haproxy implementation will be in two separate directories11:22
obondarevamotoki: we discussed it with enikanorov and came up with the following structure:11:23
amotokiobondarev: yes. i understand your concern.11:23
obondarev- drivers11:23
obondarev-- common11:23
obondarev--- agent_driver_base.py11:23
obondarev-- haproxy11:23
obondarev--- plugin_driver.py11:23
obondarev--- namespace_agent.py11:23
obondarev- agent11:23
obondarev-- agent.py11:24
obondarev-- agent_manager.py11:24
obondarev-- agent_api.py11:24
obondarev-- agent_device_driver.py11:24
obondarev*namespace_driver11:24
obondarevso in haproxy directory it is not namespace_agent but namespace_driver11:25
amotokihmm... it looks more complicated than the proposed in the patch because namespace_agent is agent side.11:25
obondarevyeah, it's agent side11:26
obondarevso we have to choose11:26
amotokithe similar situation occurs in ML2 and OVS/LB agent.11:26
obondarevhow was it resolved?11:27
obondarevif was11:27
amotokiat now, it is not resolved and we haven't discussed it yet.11:28
obondarevok11:28
obondarevso we have two variants as I see it11:28
obondarevfor haproxy11:29
obondarevhave the whole haproxy implementation in one dir but with mixed plugin/agent code11:29
amotokiDo both variants share some logics? or both implementation have diferent code both on agnet and plugin sides?11:29
*** salv-orlando has quit IRC11:30
obondarevno? it's only about file placement11:30
obondarevs/?/,11:31
amotokii am okay even with the current structure you proposed.11:31
amotokinote that when i wrote a comment, agent and drivers directories are both under loadbalancer, so i think it is not so confusing.11:31
*** amuller_ has joined #openstack-neutron11:32
*** amuller has quit IRC11:32
obondarevI'd say both under loadbalancer/drivers/haproxy dir11:32
amotokiI am often confused when i see a module with "agent_xxx". Is it an agent side or a server side? It is the only reason, but there is no more reason than this.11:33
obondarevyeah, understand11:34
amotokiIs it a consensus in LBaaS team? I just would like to know folks working on LBaaS hard.11:36
openstackgerritenikanorov proposed a change to openstack/neutron: Fix race condition in network scheduling to dhcp agent  https://review.openstack.org/7139311:37
obondarevwell, we just have a consensus with enikanorov now11:37
obondarevlooking like this:11:37
obondarev- drivers11:38
obondarev-- common11:38
obondarev--- agent_driver_base.py11:38
obondarev-- haproxy11:38
obondarev--- plugin_driver.py11:38
obondarev--- namespace_driver.py11:38
obondarev- agent11:38
obondarev-- agent.py11:38
obondarev-- agent_manager.py11:38
obondarev-- agent_api.py11:38
obondarev-- agent_device_driver.py11:38
obondarevdo you have any concerns other than namespace_driver.py placement (which is agent side)?11:39
amotokino.11:39
amotokihaproxy/agent/namespace_driver is one idea but it is no good because the length of the path becomes too long :-)11:40
amotokii agree with your idea.11:40

amotokiif we use  "plugin_drivers" instead of "drivers", how does it sound? I am not sure which is better.11:47

xuhanpaveiga, ping14:05
aveigaxuhanp: pong14:05
xuhanphave a security group question to discuss, have a minute?14:05
aveigasure14:06
xuhanpI only saw you are here:-)14:06
xuhanpI am trying to help on the security group change based our two mode design14:06
jmoureloshi all, I am trying to use python-neutronclient with python 3.3 to hit the neutron API, however I am getting several import errors like trying to import python 2 libraries like httplib instead of http.client14:06
xuhanpthe question is RA from which IP address should be allowed14:07
jmourelosthe tox.ini in the github repo has python 3.3, is it really supported? Thx in advance14:07
xuhanpaveiga, I recall the discussion with you and Shi Xiong about provider network owns the router14:07
aveigaxuhanp: it needs to come from: the subnet's gateway, if defined, and also from any on-link routers14:07
aveigaso if provider networking is in use, the gateway either needs to be defined in the subnet definition, or an external router needs to be defined and attached to the neutron network14:08
aveigaeither of those should be allowed in the security group14:08
xuhanpthe external router you mean here is the route managed by openstack, right? just want to confirm14:09
xuhanpwhich has the external gateway on it.14:09
aveigain provider network, no14:09
aveigait's a "router" entity added to neutron with the external flag set14:09
aveigameaning it's a device that neutron doesn't won14:09
aveigaown*14:09
xuhanpyep. which has the tenant network and the external network connected14:09
aveigayes14:10
aveigabasically any device added to neutron as a "router" should be allowed to issue RAs14:10
aveigabecause a user would have to add this device and therefore knows it's there14:10
aveigaas opposed to a rogue VM sending them14:10
xuhanpso the RA could be send from dnsmasq spawned by openstack or from the subnet gateway in provider network14:11
aveigayup14:11
aveigaor even from a service VM14:11
aveigalike a load balancer14:11
aveigaso long as it's listed as a router14:11
xuhanpyep. so what about DHCP?  currently from the code I can see only the dhcp from dhcp port created by neutron is allowed14:12
xuhanpwe should allow external dhcp right?14:12
*** WackoRobie has joined #openstack-neutron14:13
aveigaI don't think so14:13
xuhanpbecause it's L2 not L3?14:13
aveigaif a user absolutely wants external dhcp, let them open the ports manually in the SGs14:13
aveigaif we really need this to work, we should consider adding a dhcp agent object later14:14
aveigabut not for icehouse14:14

ihrachysany neutron client gurus here? I have a problem as follows: if Client is instantiated with token provided as arg, authentication is not done (reusing token, which is fine), so client.httpclient.auth_tenant_id and client.httpclient.auth_user_id are not filled properly, so then invoking Client.get_auth_info() fails with KeyError because there are no such properties in the object. I could fix this14:23

markmcclainyes.. the lbaas agent was running on a network node with the linuxbridge as the core plugin17:39
swestonbecause I am using that configuration with a fresh devstack install, and I cannot determine any difference between the behavior of that driver and the ovs driver, the same rules in iptables get created.17:39

markmcclainso this bug is referring to using OVS plugin and LBaaS agent17:48

*** shivh has joined #openstack-neutron18:12
markmcclainwhat we realized after was that when running with the OVS plugin the security groups weren't applied to the VIP18:12
markmcclainmainly because in original dev we didn't test SG on the VIPs at all18:13
swestonmarkmcclain: so the behavior of the security groups, is that when a group is applied to the lb member, it should then be applied to the vip?18:15
markmcclainsweston: no the behavior of the member is unique to the member18:16
markmcclainwhat folks were wanting was to apply SG rules to the VIP18:16

shivhmarkmcclain, apevec: I have a backport from master to havana/stable: https://review.openstack.org/#/c/70232/19:11
apevecshivh, that's the one of those pulled of out the gate19:11
apevecI'm well aware of it, as soon as stable gate is working, I'll reapprove it19:12
shivhapevec: thanks much19:12
apevecshivh, note that I've delayed 2013.2.2 to next week, so it'll get into that release19:13

apevecmarkmcclain, marun, otherwiseguy - do you think patch queue starting with https://review.openstack.org/65808 is also needed to stabilize neutron jobs?19:18

HenryG_How do I assign someone to a bug in launchpad?19:25
otherwiseguyapevec: i'm not sure why someone rechecked those patches since they had already actually passed verification.19:25
*** Jabadia has quit IRC19:26
otherwiseguyNow, of course, I've got to try to push them through again because the rechecks failed because the gate is dumb, at least for havana.19:26
HenryG_Or, otherwiseguy, can you assign yourself to  https://bugs.launchpad.net/neutron/+bug/1268711 ?19:26
apevecotherwiseguy, that's what markmcclain is working on, getting stable gate into shape19:27
apevecplease don't recheck before markmcclain is happy19:27
otherwiseguyapevec: right, I'm just wondering why someone rechecked when they'd *already made it through the first check*.19:28
otherwiseguyit's happened twice now.19:28
apevecin theory, if gate is working fine, recheck should just work19:29
apevecthis shows gate is not working fine19:29
*** sweston has joined #openstack-neutron19:30
otherwiseguyYes, but rechecking something that is already checked is still a waste of resources, grumble grumble. Oh well. I'll just leave the bugs alone and let people push them through whenever things settle down.19:30
apevecotherwiseguy, I guess the idea was to check the state of gate: if check is not passing, verification would fail too19:31
apevecand check in the past doesn't count19:31
apevecotherwiseguy, I'm grumble grumble too, my stable release today was ruined :)19:31

anteayaI did so because as apevec points out, stale check passes are stale19:43

marunanteaya, otherwiseguy: it's not as simple as 'this doesn't pass the check, therefore the patch is bad'20:00
marunanteaya: all of the patches in question are 'no-op'20:01
marunanteaya: they introduce functionality that is simply not used without explicit configuration, and we won't be enabling it by default in havana to avoid compatibility problems20:01
otherwiseguyanteaya: with the havana branch it mostly just seems like whether a patch will pass the check isn't particularly deterministic. :)20:02
marunanteaya: so the problem is more likely to be that the havana gate is missing patches that allow for the same degree of stability that we have in the icehouse gate20:02

ianwis anyone aware of a known issue that would cause dhcp request packets to make it to the dhcp-agent host, have dnsmasq log itself as replying but the reply packets never seen on the wire?  with ovs22:48
swestonianw: are you running with a cirros image?22:49
ianwsweston: no this is a rhel image.  my CI job has been booting probably about 200 vm's, just this one got stuck in this state somehow22:51
itzikb1Mark, Can we discuss changing history with alembic?22:51
swestonianw:  I had that issue with a cirros image, but with the linux bridge plugin though ... the issue manifests as the dhcp client dropping the packets, but you should be able to see the dhcp reply passing over the tap interface with tcpdump reporting udp checksum errors22:53
swestonianw: I think it is specific to the virtio-net kernel driver and cirros guests ... it is fixed in nova-network with a iptables mangle rule, but has not made it into neutron yet22:55
ianwsweston: hmm, ok thanks.  dumping the client side it never sees a reply.  on the dhcp-agent host i can dump br-int and see the requests, but no replies.  but dnsmasq logs the incoming request and its response22:55
