17:02:21 <LouisF> hi all
17:02:23 <igordcard> hi
17:02:29 <bcafarel> hi
17:02:32 <mohankumar> hi
17:03:16 <LouisF> here is agenda for today https://wiki.openstack.org/wiki/Meetings/ServiceFunctionChainingMeeting#Agenda_for_the_Networking-SFC_Meeting_.2810.2F6.2F2016.29
17:03:27 <yamahata> hello
17:03:48 <LouisF> anything to add?
17:04:26 <pcarver> hi
17:04:39 <LouisF> hi all
17:05:11 <LouisF> #topic progress status
17:05:16 <doonhammer> greetings
17:06:44 <LouisF> Replace OvsSfcAgent by L2 Agent Extension https://review.openstack.org/#/c/351789/
17:07:16 <bcafarel> there are some +1 reviews now, nothing noted in the code itself after last fix (thanks igordcard),
17:07:36 <LouisF> what is progress on testing this?
17:08:00 <igordcard> LouisF: I got the flows I was expecting, with the last patchset
17:08:09 <LouisF> i know that some testing has been done
17:08:42 <bcafarel> I'll fix the functional test which in fact does nothing at the moment, and I want to add some unit tests on the extension itself (most are on the ovs driver), but nothing blocking
17:09:22 <LouisF> i would like to see some more testing done before final approval
17:10:18 <LouisF> i will get more testing done
17:10:50 <LouisF> next item - Move to using OpenStack Client (OSC) https://review.openstack.org/#/c/344920/
17:11:13 <LouisF> mohankumar: what is status of testing this?
17:11:47 <mohankumar> LouisF, Got distracted with SFC-heat support and other work items . this patch needd some more  testing , will open to review soon with UT
17:12:20 <LouisF> mohankumar: ok thanks for your efforts on this
17:13:09 <LouisF> i can also start testing on osc for sfc
17:13:23 <mohankumar> LouisF , okay
17:13:39 <LouisF> mohankumar: thnaks
17:13:53 <LouisF> next item - Symmetric chain API https://review.openstack.org/#/c/308274/
17:14:42 <LouisF> pavel had started this work - I will be updating with a new patch
17:15:25 <LouisF> i will also post a new patch on the changes for the ovs driver/agent
17:15:51 <mohankumar> LouisF , great !
17:16:12 <LouisF> next - Networking-sfc / OVN driver spec https://review.openstack.org/#/c/333172/
17:16:16 <igordcard> LouisF: is that based on the new agent?
17:16:37 <LouisF> igordcard: it will be once that is merged
17:17:26 <LouisF> all - please review this
17:17:53 <LouisF> doonhammer: there is a presentation at the summit on this - right?
17:17:54 <doonhammer> LouisF: I think one of next steps is to get the draft OVN spec done and to the OVN/OVS team
17:18:11 <doonhammer> LouisF: If we get it put together :-)
17:18:30 <LouisF> doonhammer: yes
17:18:36 <doonhammer> LouisF: Also I think we might be able to have a f2f in Barcelona
17:19:03 <LouisF> doonhammer: yes that will be very useful
17:19:21 <doonhammer> with the OVS/OVN team so iif we have some details to discuss by then it would be good
17:20:14 <LouisF> doonhammer: we can go over the proposed changes to ovn-nbctl and the SB logical flows with them
17:20:33 <doonhammer> LouisF: yup that would be ideal
17:21:44 * sridhar_ram has couple of items to discuss on tacker+sfc, if time permits
17:21:57 <LouisF> sridhar_ram: ok
17:22:28 <sridhar_ram> LouisF: thanks, can i go now ?
17:22:42 <LouisF> sridhar_ram: go ahead
17:23:08 <sridhar_ram> LouisF: 1st.. it will be good if tacker & sfc team can meet for a F2F in Barcelona..
17:23:24 <LouisF> sridhar_ram: definitely
17:24:05 <sridhar_ram> LouisF: i'm not travelling .. but sripriya is the acting PTL.. we have identified a design summit slot for this
17:24:30 <LouisF> sridhar_ram: let me know the details
17:24:59 <sridhar_ram> LouisF:  here is the agenda .. https://etherpad.openstack.org/p/tacker-ocata-summit
17:25:32 <sridhar_ram> LouisF: one possible slot is Friday AM (already penciled in).. but I'll ask sripriya to coordinate with you and the sfc team
17:25:39 <sridhar_ram> sripriya: ^^^
17:26:01 <sripriya> sridhar_ram: catching up
17:26:07 <sridhar_ram> LouisF: next, the issue related to network_src_port_id restriction in the classifier..
17:26:11 <LouisF> sridhar_ram: i will contact her
17:26:23 <sridhar_ram> LouisF: http://lists.openstack.org/pipermail/openstack-dev/2016-October/105153.html
17:26:43 <sridhar_ram> LouisF: I've described the downside of this here ^^^
17:26:57 <sridhar_ram> LouisF: anyway we can address and remove this restriction ?
17:28:50 <LouisF> sridhar_ram: there are several issues - 1. if the logical source port is not specified the ovs classifier rules must be installed on all compute nodes
17:30:43 <LouisF> there is also an issue with matches on traffic entering via a router
17:31:23 <LouisF> and this causes a chain path loop :(
17:31:31 <sridhar_ram> LouisF: I see
17:32:03 <sridhar_ram> LouisF: I'd like to request for some ideas.. perhaps out of the box to atleast reduce this restriction..
17:32:12 <sridhar_ram> LouisF: can this classifier be applied only when a vif matching a specific "source critieria" .. perhaps we can use port tagging ?
17:32:40 <LouisF> sridhar_ram: we are open to explore ideas on this
17:32:45 <sridhar_ram> LouisF: btw, traffic entering via a router is a huge use-case that we need to address
17:32:59 <LouisF> sridhar_ram: agree
17:33:08 <sridhar_ram> LouisF: okay.. didn't mean to hold your meeting, just want to bring this up..
17:33:46 <sridhar_ram> LouisF: perhaps this can be discussed further in the F2F summit meeting
17:33:55 <LouisF> sridhar_ram: noted - we are actively looking at options as we are aware of the issue
17:34:06 <sridhar_ram> LouisF: thanks
17:34:16 <LouisF> yes we should definitely discuss
17:34:48 <LouisF> sridhar_ram: any other issues from your side?
17:34:58 <sridhar_ram> LouisF: no, that is it for now :)
17:35:53 <LouisF> sridhar_ram: ok
17:36:29 <LouisF> sridhar_ram: btw anil did a demo at the odl summit - right?
17:36:52 <sridhar_ram> LouisF: yes, he did .. neutron-sfc + ODL-sfc .. i heard it went really well
17:37:08 <LouisF> sridhar_ram: is there video on that?
17:37:26 <sridhar_ram> LouisF: for our FFG talk we are preparing a demo of Tacker --> n-sfc--> ODL-SFC ..!!
17:37:52 <sridhar_ram> LouisF: building on top of Anil's
17:38:26 <LouisF> sridhar_ram: great - we should discuss the talk later
17:38:35 <sridhar_ram> LouisF: sounds good
17:40:50 <LouisF> igordcard: i missed the nsh work https://review.openstack.org/#/c/373465/
17:41:05 <LouisF> what is the status of that?
17:41:08 <igordcard> LouisF: working right now
17:41:11 <igordcard> it's almost done
17:41:26 <igordcard> it's given me more trouble than I antecipated, but it's almost done now
17:41:44 <LouisF> igordcard: great - looking foward to the update
17:41:51 <igordcard> I'm fixing the classification flows when there no sfc-proxy is needed
17:41:59 <LouisF> igordcard: ok
17:42:00 <igordcard> s/there//
17:42:27 <igordcard> I plan to start asap the sfc graphs work, which will directly build on top of this one
17:42:34 <LouisF> igordcard: will you be in barcelona?
17:42:59 <igordcard> I will rebase the patches to bernard's ovs agent later, likely after the summit
17:43:04 <igordcard> yes
17:43:26 <LouisF> igordcard: we should have a design session
17:43:42 <igordcard> LouisF: yes!
17:44:11 <LouisF> we can discuss future work
17:45:51 <igordcard> I plan on doing some work on the common classifier for the next cycle as well
17:46:09 <LouisF> igordcard: ok
17:46:20 <igordcard> when is networking-sfc expecting to shift to a neutron classifier? when there's one
17:46:28 <LouisF> igordcard: yes
17:47:18 <LouisF> igordcard: regaing this bug: https://bugs.launchpad.net/networking-sfc/+bug/1630657

17:47:40 <LouisF> can you attach steps to reproduce
17:48:26 <igordcard> LouisF: yes, but it's how cathy says (just read)

17:49:55 <igordcard> okay
17:50:29 <LouisF> ok this is all i have
