amotokipc_m: and if necessary let's fix HEAD to always match the real "head".12:35
pc_mamotoki: How do we do that?12:35
amotokipc_m: neutron repo has a check to match "HEAD" to the migration head so that we can avoid migration branches.12:36

amotokipc_m: it is better to avoid raw database query. I believe it is a base start line.12:42
amotokihopefully we can handle the default value in the logic not in db records (touched by db migration)12:43

amullerpc_m: OK I'm not sure what's going on in that patch hopefully Armando will be able to help15:12
georgem1I was doing a port scan against my public IP space and I noticed that port 9697 is exposed on the outside on all the IP's owned by neutron routers, and I'm trying to find a way to close this access.15:12
georgem1I think it's a security issue to have a tenant lock down his instances but still open up a web service on his public IP space, what do you think?15:12
*** annegentle has quit IRC15:13

georgem1amuller: any chance it will be backported to juno? I think it's a security issue to have a web service open on a public IP without the cloud admin or the tenant being able to limit access to it15:17
amullergeorgem1: You can contact Cedric (ZZelle on IRC) and ask him to backport it. It looks like a backportable patch.15:17

*** nmagnezi has joined #openstack-neutron16:29
ihrachyshkaSteap, hey! ok, good to know :) so I am concerned that py34 environment is currently hard to debug for multiple reasons16:29
ihrachyshkaSteap, first, it is just very verbose now16:29
ihrachyshkaso it's hard to spot a failure16:29
ihrachyshkathat would not be a problem if the env actually supported regexps though16:30
ihrachyshkabut it seems that it does not, and just runs all tests no matter which args are passed16:30
Steapyeah16:30
ihrachyshkaso I got a failure in feature/qos, and it's not clear how to make any sense of the output16:30
SteapI've seen your bug report16:30
ihrachyshka(the fact that it fails in gate only does not help either)16:30
Steapso basically, I intend to get rid of the crazy py34 env ASAP16:30
*** Piet has joined #openstack-neutron16:31
ihrachyshkaSteap, like... how?16:31
Steap(I have 5124 tests passing, out of 7236)16:31
Steapihrachyshka: well, once the port is complete, we can just use the default env with {posargs}16:31
Steapas we do with py2716:31
*** fzdarsky has quit IRC16:31
ihrachyshkaSteap, well, it still can be a long road, depending on whether we killed the worst issues, or instead left them for the final flush16:32

Steapihrachyshka: what I do is I fix an issue, run teh whole test while I eat/sleep/hack on somehting else16:35
Steapunless I really need to debug a single test16:35
Steapin which case I source the environment16:35
Steapand run python -m testtools.run foo.bar.baz16:35
Steapwould this be acceptable ?16:36
*** agireud has quit IRC16:36
ihrachyshkaah right. yeah, that's a bit painful, but can be ok as temp workaround16:36
Steapyeah, it is meant as a workaround16:36
clarkbyou can also let py34 be the default test env that does the default things16:36
clarkbthen create a second target that only runs the listed tests16:36
*** luqas has quit IRC16:37
ihrachyshkaclarkb, then py34 should be made non-voting16:37
Steapyeah, if we were to that16:37
SteapI would keep py34 as is16:37
Steapand use py34-debug as a "manual" thing16:38

Steapso that we do not have any regressions16:39
clarkbSteap: and you can do that, just do it wiht the special target16:39
Steapyeah, right16:39
ihrachyshkaclarkb, mostly to avoid regressions, but I get your point, it may actually be the thing to do. Steap, how often do you envision us regressing if it's non voting?16:39
Steapbut well, that means sending more patches to project-config16:39
*** sdae is now known as sdake16:39

ihrachyshka;) nah, that's definitely not the case ;)16:40
*** annegentle has joined #openstack-neutron16:40
SteapI mean, having the gate voting is quite solid16:40
Steaphow many people actually need to debug py3-related issues on Neutron ?16:40
ihrachyshkabut yeah, there is a balance. let's at least document the hack around in tox.ini for those being hit by a failure, and maybe move as quick as possible on getting it full suite ;)16:40

cathy_armax: hi22:59
*** r-daneel has quit IRC23:00
armaxI was going through the api doc again this morning23:00
cathy_armax: Good. I have posted replies to the new comments from Paul. Have you seen those?23:01
armaxone question I had was regarding the implicit assumption behind the chain creation23:01
cathy_armax: armax ok, let me know your question and I will give it a try23:01
*** fawadkhaliq has quit IRC23:02
cathy_what implicit assumption are you referring?23:02
armaxdo we assume that we can create a chain amongst ports that belong to separate networks?23:02
cathy_what d you mean by separate networks, could you be more specific?23:03
armaxsay I want chain [{'p1': 'p2'}, {'p3': 'p4'}, {'p5': 'p6'}]23:03
cathy_ok23:04
armaxcan p1, p2 belong to Network 1 and p3, p4, p5, p6  belong to Network 223:04
armaxor must they belong to the same logical network?23:04
Sukhdevkevinbenton: Hey Kevin - please see my comment on - https://review.openstack.org/#/c/198182/23:05
kevinbentonSukhdev: so you have encountered cases where the host_id field is set but the device_owner hasn't been?23:06
cathy_I don't think we have any restriction there. The user is supposed to already set up network 1 and network 2 and network 1 and network 2 can communicate . The chain is on top of the existing network and the packets will be tunneled through them.23:06
armaxcathy_: the reason why I am asking if that there would be obvious implication to the way the implementation needs to be23:06
armaxcathy_: because there may be routers involved, security groups etc23:07
Sukhdevkevinbenton: I was discussing this with a co-worker. This was written almost 2 years ago - and we were scratching our heads trying to remember - so, we both decided that it is safe to be defensive - as we must have had a case which forced us to put this test23:08
kevinbentonSukhdev: ok. if you're comfortable with it then i won't block it23:09
cathy_So it is required that the user already set up the underlying networks. Then the user can request a flow to be steered through a sequence of VMs that can be scattered among the networks. But how to set up the two networks and the process of setting up the underlying networks are outside the scope of the SFC project23:09
Sukhdevkevinbenton: It seems harmless - it may be dangerous to remove it :-)23:09
cathy_Does this make sense? I can add this calrification to the spec.23:10
armaxcathy_: ok, that’s fine, but we should probably make that clear23:10
cathy_armax: sure. Agree23:10
cathy_I will add the calrification.23:10
kevinbentonSukhdev: right, but it might be implying something can happen that might not :)23:10
armaxcathy_: ok, tnx23:10
armaxcathy_: next point I wanted  to clarify was the way a chain can be used23:11
*** absubram has quit IRC23:11
*** thedodd has quit IRC23:11
cathy_You are welcome.23:11
cathy_could you be more specific?23:12
Sukhdevkevinbenton: you are right - we did run couple of test case (but definitely not exhaustive) and noticed that both were always set - it is hard to conclude though23:12
armaxcathy_: the head and tail of the chain described in the proposal mention Service Functions23:12
*** annegentle has joined #openstack-neutron23:12
cathy_let me take a look at the head and tail in the spec to see whether it causes confusion.23:13
armaxcathy_: it would be useful how it could be practically used when you have regular workload instances23:14
armaxcathy_: in the picture23:14
*** zhenguo has joined #openstack-neutron23:14
*** Ila has joined #openstack-neutron23:14
cathy_Ok, what that means is that the chain is composed of an ordered sequence of SFs. The first SF is the head of the chain and the last SF is the tail, that's it. But the head and tail do not mean the flow source and flow destination. The flow source and destinaiton is defined in the flow classifier.23:15
armaxthat I get23:16
armaxcathy_: what I understand is that traffic matching the classifier goes through the chain23:16
armaxcathy_: right?23:17
cathy_The combination of source params defined in the flow classifier identifies the flow source.23:17
*** hichihara has joined #openstack-neutron23:17
cathy_armax: yes!23:17
armaxcathy_: right, but in the context of overlapping IP’s how’s that going to work?23:17
cathy_maybe I would remove the head and tail to avoid the confusion.23:17
armaxcathy_: in other words, in a multitenant environment the matching must be tenant aware somehow23:18
armaxcathy_: or am I missing something?23:18
*** mleroy has quit IRC23:18
*** padkrish_ has quit IRC23:18
cathy_Yes, a chain is created for a tenant. There is a tenant ID in the parameter of the chain API.23:19
cathy_Different tenants will not share the same chain23:20
armaxcathy_: it would be also good to show ‘who’ is the user calling some of the commands exemplified in the proposal and whether we’d want to allow certain users to perform certain actions23:20
cathy_But different applications flows of the same tenant should share the same chain23:20
armaxcathy_: ok, so no chain nor classifier sharing?23:20
cathy_yes, no sharing among tenants23:21
armaxcathy_: ok, thanks23:22
cathy_The user could be an admin or any application built on top of it.23:22
armaxcathy_: we should try and document these ‘implied’ assumptions as much as we can23:22
armaxcathy_: next thing23:22
armaxcathy_: the parameters in the port chain23:22
armaxcathy_: what’s the encapsulation for?23:22
cathy_armax: I will try my best to add more clarification.23:23
armaxcathy_: and what about the failure_policy? we should document what these are for or are going to be used23:23
*** padkrish has joined #openstack-neutron23:23
cathy_armax: the answer to this will be long. Let me try to explain.23:23
*** britthouser has quit IRC23:23
armaxcathy_: that’s ok, perhaps we don’t have to take this right now but it’d be good to capture it in the proposal23:24
armaxcathy_: I would like to understand the encapsulation bit though23:24
*** gildub has joined #openstack-neutron23:26
Ilacarl_baldwin: haleyb:Could you please review the patch https://review.openstack.org/#/c/122024/ and https://review.openstack.org/#/c/123815/23:26
*** salv-orlando has quit IRC23:26
cathy_armax: So in IETF, there have been discussion on how to add chain-ID and metadata to chain flow packets. chainID can be used instead of n-tuple matching in the vSwitch forward table for next hop forwarding of the chain flow packets. This will greatly improve the vSwitch performance. It can also be used to identify different chains' packets when multiple chains cross at the same SF VM. .23:27
armaxcathy_: understood23:27
armaxcathy_: but that would really be an implemention detail not exposed to the user, correct?23:28
*** merooney has quit IRC23:28
armaxcathy_: the encapsulation bit is not really exposed to the user at all?23:28
cathy_So there is a standard spec on the chain ID and metadata encapsulation format. and this encap parameter is for specifying that23:28
armaxcathy_: correct?23:28
*** krtaylor has quit IRC23:29
cathy_armax: So the classifier and vSwitch needs to know what encap to use and tag the packets of a chain flow since there could be different encap mechanism, such as IETF Service chain header encap, VLAN, or others23:30
armaxright23:30
*** carl_baldwin has quit IRC23:30
cathy_A consistent encap mechanism needs to be used for a chain23:30
armaxcathy_: but that would be determined by the ports that make up the chain23:30
armaxcathy_: the other problem I can see is that if we allow ports from different networks to be chained, there’s validation required as now different networks can have different encap23:31
*** ijw has quit IRC23:31
cathy_Yes, but there management plane(the Neutron layer) needs to coordinate the encap mechanism among the SF VMs and the vSwitches.23:31
*** padkrish has quit IRC23:32
*** padkrish has joined #openstack-neutron23:32
*** padkrish has quit IRC23:32
*** padkrish has joined #openstack-neutron23:33
*** ijw has joined #openstack-neutron23:33
cathy_Service VMs themselves will not communicate in the data path with vSwitch on the encap mechanism. There is no protocol defined for that, and the industry direction is to have a central management plane to coordinate that with the SDN thought,23:33
*** annegentle has quit IRC23:34
armaxcathy_: not sure I understand for first statement on ‘ervice VMs themselves will not communicate in the data path with vSwitch on the encap mechanism.’23:35
armaxcathy_: regardless of how the underlying mechanism implements the chain, I am thinking that the API/Neutron glue needs to be expressive enough23:36
armaxcathy_: but more importantly that the Neutron model doesn’t get in the way of the implementation23:37
cathy_armax: Yes, different networks can have different encaps. So the more accurate mechanism will be that we specify different encap mechanism for different segments of the chain. But that could make the data path complicated. In most cases, IETF encap will be supported since it has become the standard. So to make it simple which will cover most scenarios, we will have a encap mecahnism per chain instead of per Service Function23:37
armaxcathy_: what encap are you talking about specifically?23:38
cathy_the NSH encap which is actually a merged spec of the original nsh and SCH chain header encap mechanism. I can forward you that email.23:39
armaxcathy_: merged spec where?23:39
cathy_I will forward you the link to the spec23:39
armaxcathy_: I can hardly think that NSH is an IETF standard23:40
armaxcathy_: so I would honestly refrain from using for the built-in solution on top of OVS23:40
cathy_in IETF. originally there are two proposals on encapsulation. One is NSH, the other is SCH (actually SCH is proposed by my and my ao-authors). Now these two specs merged and the new merged spec is still called NSH:-)23:41
armaxcathy_: but that doesn’t make them standard23:41
armaxeither way23:41
*** krtaylor has joined #openstack-neutron23:41
armaxcathy_: what’s the current status of the RFC?23:42
*** marrusl has quit IRC23:42
*** Longgeek has joined #openstack-neutron23:44
cathy_Now it is a standard working spec and will become a RFC (maybe it already become a RFC. I have been frustrated by the IETF SFC group and give up on my part and did not track closely now). I am pretty sure it will become a RFC since no other competing spec any more.23:44
kevinbentonzzzeek: ping23:45
armaxcathy_: I know there are already a couple of other IETF RFC’s  for this type of advanced metadata tagging at the encapsulation layer23:45
zzzeekkevinbenton: hi23:45
cathy_OVS already has some support of this IETF encap mechanism.23:45
kevinbentonzzzeek: hey, given a relationship on a model. can i get a reference to the db model that it's related to?23:46
armaxcathy_: that’s a patch that won’t be making into mainline linux for quite some time23:46
zzzeekkevinbenton: yes23:46
zzzeekMyClass.relname.property.mapper23:46
armaxcathy_: if we really want to keep this open and free from vendor pollution we should stick to what we have in vanilla OVS, at least for the built-in implementation23:46
cathy_But for SFC, that is the only spec which becomes standard working document, all others are not accepted/considered. Even mine is accepted, it has been merged with NSH.23:47
armaxcathy_: then surely we’ll work out allow various parties to experiment with other mechanisms23:47
kevinbentonzzzeek: ok. and MyClass is the one with the relationship?23:47
zzzeekkevinbenton: yes23:47
armaxcathy_: but that shouldn’t be our reference framework23:47
cathy_Yes, that is why I add the encap mechanism in the API to allow different encap instead of one23:48
armaxcathy_: that’s not the point, before we get that widely accepted we can’t use it23:48
armaxcathy_: if you can provide me the link of the draft you’re referring too I’d love to look into it23:49
armaxcathy_: did the other expired?23:49
*** Longgeek has quit IRC23:49
kevinbentonzzzeek: ok. i'm getting a missing attribute error23:50
kevinbentonzzzeek: i must be calling it on the wrong hting23:50
kevinbentonzzzeek: but i can dig into it with your hint23:50
kevinbentonzzzeek: thanks23:50
zzzeekkevinbenton: good luck23:50
kevinbentonzzzeek: oh, :)23:51
kevinbentonzzzeek: relname was a variable in your example referring to relationship name :)23:51
kevinbentonzzzeek: i was typing relname23:51
openstackgerritAaron Rosen proposed openstack/neutron: Do not use dnsmasq process as nameserver  https://review.openstack.org/19934623:51
cathy_NSH will be a RFC and is already kind of widely accepted. I am not sure what other encap can prevail that. But we do not need to implement the vendor specific type-1 encap which is in an OVS private version. We can implemtn type-2 which is not vendor specific and is required by many people for flexibility of carrying variable length metadata in TLV format. Type-1 is fixed length and tailored to a vendor's hardware implemntat23:51

armaxcathy_: are these the two: https://datatracker.ietf.org/doc/draft-quinn-sfc-nsh/  and https://datatracker.ietf.org/doc/draft-zhang-sfc-sch/23:55
armaxcathy_: it looks like it has23:55
cathy_yes23:55
armaxcathy_: just a week ago23:55
*** marrusl has joined #openstack-neutron23:55
armaxcathy_: so you’re referring to this one? https://datatracker.ietf.org/doc/draft-quinn-sfc-nsh/23:56
*** yuanying has quit IRC23:56
cathy_OK, so what encap we should use for reference implementation? I think a new chain-ID definitely has benefit.23:57
cathy_armax: yes23:58
cathy_and NSH and SCH are the only ones that have chain-ID.23:59
armaxcathy_: why can’t we do traffic steering with a pure openflow approach? I may sucks performance wise, but that would buy us more time until the get more clarity to what de-facto solution emerges23:59
