russellbgsagie: o/15:47
gsagiehi russell, hope you had fun in your vacation15:50
*** armax has quit IRC15:50
russellbi did :)15:51
russellbnow back to poking at this stuff15:51
russellbtrying to get tempest working15:51
gsagiesomeone approached me last week about doing the security group task, did he talk with you by any chance?15:52
gsagiegave him some instructions but i was without internet connection for few days :|15:53
russellbdiscovered another feature gap ... we don't support administratively setting port state to up/down15:55
russellbso that makes a test fail15:55
russellbi think i can implement that in OVN pretty easily though15:55
gsagiebtw, regarding check if ubuntu : this is from devstack http://pastebin.com/cthBD1hg15:57
gsagiehow will you implement it? is there admin status for logical ports?15:58
russellbnot yet :)15:58
gsagiedon't remember i saw it15:58
russellbbut i was going to propose adding it15:58
gsagieahh ok :)15:58
russellbseeing some random failures too ... one was caused by a timeout in ovsdb code: http://logs.openstack.org/80/194680/1/check/check-tempest-dsvm-networking-ovn/287530d/logs/screen-q-svc.txt.gz?level=TRACE15:59
russellbhaven't looked any closer at that one yet15:59
*** armax has joined #openstack-neutron-ovn16:05
russellbgsagie: looks like apparmor is on non-debian distros too16:06
gsagieahh ok16:08

gsagierussellb : regarding your admin-up-down patch, nice work but don't you somehow need to delete the old flow first?18:45
gsagiei am not in front of the ovn code right now but just wondering how is that flow getting deleted18:45
russellbgsagie: it happens automatically18:45
russellblike magic18:45
gsagieheh ok, so they read all the current flows, add the new ones and delete anything that was changed18:46
russellbexcept it's actually clever software and not magic ..18:46
gsagieok :)18:46
gsagiebecause you usually you compare open flow by the match, and here you only changed the action18:47
gsagiebut guess will look at the code18:47
russellbis where it happens for openflow18:49
russellbmy changes only affect pipeline, a layer up18:49
russellband the openflow handling seemed to already do the right thing18:49
gsagieyeah, they have a comment there that they also check for changed actions18:49
gsagierussellb : i like the idea to block it with pipeline rule, however OVSDB has support for  Interface admin up/down19:03
russellbgsagie: yeah, i thought of that as i was posting it  ...19:04
gsagieso you can basically update OVSDB19:04
gsagiethe local one19:04
russellbwhich is probably a more definitive and reliable way of ensuring no traffic passes19:04
russellband doesn't disturb the flows like this dows19:04
gsagieprobably should be added to the binding entry19:05
gsagie(not that i like it, but thats the only notion of logical port that the controller can see)19:05
gsagiei mean the port admin status..19:06
russellbgsagie: which table/column in Open_vSwitch is it that you're referring to?19:09
gsagieto set the admin status?19:09
russellbI see admin_state in Interface, but that seems to be a reflection of the network device state, not something you set via ovsdb19:09
gsagieits in the Interface table19:09

*** markmcclain has quit IRC19:12
gsagiei am not sure what you mean "reflection of the network device state" , i have never tried it but i assume you can set it "up" or "down" no?19:12
*** markmcclain has joined #openstack-neutron-ovn19:13
gsagiethe link state is basically the operational status19:13
gsagiebut just saw it there, never tried to set it19:13
gsagieyou can try to set it with ovs-vsctl and see what happens19:14
russellbit's a read-only column19:14
russellbi was looking at the ovs code to see what it does19:14
russellbalso googled and found this http://openvswitch.org/pipermail/discuss/2014-April/013644.html19:14
russellbsounds like there's a way to do it with openflow instead19:14
gsagieahh yes, nice finding! :)19:16

gsagieyeah that message basically call the net device admin configuration method19:26
gsagiestrange that its not supported with OVSDB19:28
