14:01:14 <yamamoto> hi
14:01:28 <mlavalle> Hi yamamoto, happy New Year!
14:01:37 <yamamoto> happy new year
14:01:47 <amotoki> hi happy new year
14:02:07 <mlavalle> hi amotoki!
14:02:18 <mlavalle> is this your first day after vacation?
14:02:38 <amotoki> yes, so I haven't reviewed much..
14:02:45 <yamamoto> 2nd day for me
14:02:46 <mlavalle> that's ok
14:02:50 <mlavalle> ohhhh
14:03:04 <mlavalle> did you guys went anywhere nice?
14:03:19 <amotoki> in japan we usually have new year holidays till Jan 3
14:03:32 <mlavalle> ah, good to know
14:03:57 <amotoki> instead of Christmas :)
14:04:09 <mlavalle> of course
14:04:22 <mlavalle> ok, let's get going
14:05:40 <mlavalle> yamamoto: thanks for the patchset with the new rfe labels
14:06:03 <amotoki> https://review.openstack.org/#/c/528189/
14:06:34 <mlavalle> amotoki: thanks
14:06:46 <mlavalle> I think we are all in agreement. Aren't we?
14:06:55 <amotoki> yes, sure
14:07:29 <mlavalle> so if by the end of my day today we don't get any other feedback, I am going to W+ it
14:07:39 <mlavalle> ok?
14:07:45 <yamamoto> fine for me
14:07:52 <amotoki> sounds good
14:07:56 <mlavalle> ok
14:08:10 <yamamoto> i'll add new tags to existing rfes once it was merged
14:08:21 <mlavalle> This is the list we have today: https://bugs.launchpad.net/neutron/+bugs?field.status%3Alist=Triaged&field.tag=rfe
14:09:07 <mlavalle> I am going to skip Neutron cells aware. The agreement last time was to have someone start developing a POC
14:09:37 <mlavalle> using approach in #5
14:10:01 <mlavalle> unless anyone wants to add something....
14:10:34 <yamamoto> nothing to add from me
14:11:04 <amotoki> is anyone moving this forward?
14:11:08 <amotoki> on POC
14:11:19 <mlavalle> not that I am aware of
14:11:26 <mlavalle> amotoki: interested?
14:11:49 <amotoki> i haven't looked into it yet
14:12:06 <mlavalle> ok, take a look and let us know
14:12:18 <amotoki> i am interested in it, but I need to move some API stuffs forward
14:12:52 <mlavalle> ok, let us know if you make free up some bandwidth for it
14:13:02 <mlavalle> can free up^^^^
14:13:17 <amotoki> okay
14:13:34 <mlavalle> Next one is https://bugs.launchpad.net/neutron/+bug/1715386
14:13:35 <openstack> Launchpad bug 1715386 in neutron "[RFE]Support routing traffic based on subnet" [Wishlist,Triaged] - Assigned to zhaobo (zhaobo6)
14:16:29 <mlavalle> I made another pass a copuple of days ago at the spec here: https://review.openstack.org/#/c/523658
14:17:49 <amotoki> i haven't looked at the spec proposed yet. From the bug description, it sounds a valid use case and the spec will help our understanding.
14:18:26 <mlavalle> can you elaborate on the valid use case part?
14:18:55 <mlavalle> I would like to hear your thoughts
14:20:38 <amotoki> ah... the bug description says "some specified source IP/CIDR". it sounds source routing.
14:20:47 <mlavalle> correct
14:20:54 <mlavalle> source based routing
14:21:02 <amotoki> my original impression might be wrong....
14:21:17 <mlavalle> no, it is correct
14:21:33 <mlavalle> at its essence, the proposal is source based routing
14:22:00 <amotoki> what I thoguht first is something like AWS VPC, where we can determine external gateway based on routing table.
14:22:21 <amotoki> it is not based on source-based routing
14:23:05 <mlavalle> ahhh, ok I see what you say
14:24:33 <amotoki> yamamoto: i think you already looked into the spec. any comment?
14:25:00 <haleyb> ihar had a good point - can we use SFC for this, and if so, why do it here again?
14:25:31 <yamamoto> i have never understood why multiple routers are not enough for the given use cases.
14:26:47 <amotoki> yeah, ihar had a good point. In my understanding, the current SFC does not support this model, but it sounds worth investigated
14:27:18 <mlavalle> amotoki, haleyb: if you have some time, would you leave some feedback in the spec?
14:27:37 <amotoki> sure
14:28:04 <mlavalle> any other comments from someone?
14:28:13 <haleyb> mlavalle: sure.  my other thought is a routing VM
14:29:45 <mlavalle> ok, moving on...
14:29:51 <mlavalle> https://bugs.launchpad.net/neutron/+bug/1717560
14:29:52 <openstack> Launchpad bug 1717560 in neutron "[RFE] allow to have no default route in DHCP host routes" [Wishlist,Triaged]
14:32:44 <mlavalle> For this one armax made an alternative proposal in comment #15, based DHCP extra options
14:33:16 <mlavalle> haven't heard back from Thomas
14:33:44 <mlavalle> tried to ping him in the Neutron channel
14:33:48 <mlavalle> he is not there
14:35:09 <haleyb> one other thing i didn't see in the bug is what about the case where a VM has two interfaces in the same subnet?  egress spoof checking causes problems with that, and could even in other cases
14:35:31 <haleyb> it's a little orhagonal i understand
14:35:50 <mlavalle> My thinking is that if we don't here from him by next meeting, we can conclude he doesn't want to pursue it anymore
14:35:56 <mlavalle> hear^^^^
14:36:39 <haleyb> but if i have two interfaces in different subnets i have to configure the VM to always use the source IP only on the interface it is configured on, which is part of the special setup he mentions
14:36:45 <mlavalle> I was tempted to arrive at that conclusion last night. But with the Holidays, I thought we shoould probably wait a little longer
14:36:47 <haleyb> neutron can't help with taht
14:37:22 <mlavalle> haleyb: would you leave some feedback there
14:37:25 <mlavalle> ?
14:37:42 <haleyb> mlavalle: sure, i hadn't even noticed that bug before
14:39:04 <mlavalle> any other thoughts from someone?
14:39:18 <yamamoto> +1 to wait for another week. but i guess it isn't critical as far as he can re-open it.
14:40:51 * mlavalle leaving a note in the RFE
14:42:27 <mlavalle> Next one is https://bugs.launchpad.net/neutron/+bug/1718605
14:42:28 <openstack> Launchpad bug 1718605 in neutron "[RFE] Support sub-string matching when filtering port with IP address" [Wishlist,Triaged] - Assigned to hongbin (hongbin034)
14:45:25 <haleyb> mlavalle: who is the approver for this one?  there were two reviews and they seem about complete
14:45:28 <mlavalle> I had a conversation with mriedem last night about it. Left a summary in#8
14:45:29 <amotoki> what we need is now clear and I think we approve this.
14:45:59 * haleyb didn't want to +2 since someone else might approve
14:46:44 <mlavalle> haleyb: yeah, I also wanted to wait for this meeting to formally approve the work
14:46:58 <mlavalle> yamamoto: do you agree approving this?
14:47:02 <yamamoto> yes
14:47:09 <mlavalle> haleyb: you good with it?
14:48:14 <mlavalle> ok, approved it is
14:48:21 <haleyb> mlavalle: yes i think they're fine, would be good to have someone else look at the changes since i only remember slaweq recently
14:48:35 <mlavalle> haleyb: I will review today
14:49:13 <mlavalle> ok, approved it is
14:50:02 <mlavalle> Next one is https://bugs.launchpad.net/neutron/+bug/1727578
14:50:03 <openstack> Launchpad bug 1727578 in neutron "[RFE]Support apply qos policy in VPN service" [Wishlist,Triaged]
14:52:23 <mlavalle> This one was brought during the QoS meeting by slaweq this past Tuesday
14:53:08 <mlavalle> he indicated interest on it from the QoS team point of view, so I asked him to mark it triaged, so it can be discussed here
14:53:18 <yamamoto> i guess the feature is nice to have.  to me it isn't clear how the reference impl would look like though.
14:53:24 <slaweq> hi, there is some specs for it also: https://review.openstack.org/#/c/531074/
14:53:35 <slaweq> but I didn't have time to read it yet
14:54:28 <mlavalle> would we feel comfortable approving the RFE and taking the discussion to the spec?
14:54:38 <yamamoto> yes
14:55:01 <mlavalle> amotoki: how about you?
14:55:11 <amotoki> I am fine to approve the RFE though i am not sure how we can actually implement it in the reference impl, but it can be dsicussed in the spec
14:55:22 <mlavalle> ok cool
14:56:19 <mlavalle> approved it is
14:56:34 <mlavalle> and that was the last RFE we had for today
14:56:58 <mlavalle> so we will be returning a whopping 4 minutes to everybody's agenda :-)
14:57:27 <mlavalle> haleyb, slaweq: thanks for popping in. Your insight is always welcome
14:57:46 <slaweq> :)
14:57:48 <mlavalle> next meeting is on Thursday, 2200UTC
14:57:51 <haleyb> np, glad to help
