#openstack-nova - 2024-10-16
14:38:05 sean-k-mooney you are misussing that term based on the current agreed usage
14:38:24 sean-k-mooney a a use with an admin role is a global admin
14:38:40 admiyo can I have a project specific flavor ?
14:39:04 sean-k-mooney technially yes private flavor are a thing and only admins can create them on behayce fo end users
14:39:15 sean-k-mooney a normal user of a public cloud should not be allowed ot od that with the member role
14:40:04 sean-k-mooney admiyo: a new role that is seperat eform the curent heriacy was proposed if to have project scoped elevated access
14:40:07 sean-k-mooney https://governance.openstack.org/tc/goals/selected/consistent-and-secure-rbac.html#implement-support-for-project-manager-personas
14:40:11 dansmith flavors are also a lot more involved than they were in 2010 and require knowledge of the backend to some degree to set up in a lot of real-world cases, like knowing what hardware is available and in what configuration
14:40:14 sean-k-mooney its called the project manager role
14:40:40 sean-k-mooney that is part of phase 3 and we are in the midel of pahse 2 right now
14:41:00 dansmith and as sean-k-mooney has been saying, I think this is not nova-specific and also pretty much a sailed ship at this point
14:41:17 admiyo So it looks like you DO have a plan in place to fix the bug. It should not be closed as won't-fix
14:41:36 sean-k-mooney the bug is honestly invlid
14:42:06 sean-k-mooney we have specificly decied to not scope the admin role
14:42:16 dansmith agree
14:42:17 admiyo Well, no. It is not invalid.
14:42:23 sean-k-mooney we are keeping it as a global role and providing a new manager role
14:42:44 sean-k-mooney the manager role can be scoped to project or domains
14:42:53 sean-k-mooney when ever we implemet it
14:43:06 admiyo The admin role has been removed from being a project scoped role, that is fine. But do those APIs still look for the project ID on the token? That was the problem before. If nova has removed that restriction, then you have fixed it.
14:43:38 sean-k-mooney thats a diffent question.
14:43:39 admiyo Becuase other projects beside Nova "reqquired" if for day to day operations. It was a logicial contradiction
14:44:19 sean-k-mooney you realise that cinder or glance until recently reuiqred a proejct in the url
14:44:26 sean-k-mooney not just in the headers
14:44:27 admiyo Oh yes I do
14:45:15 admiyo that actually made certain things easier to do, so I understand why they did it. I am still not certain they were wrong, but having it consistent across all OpenStack was more important
14:45:19 sean-k-mooney to answer your question, weither or not we actuly need a project id depends on a few things, the policy file/default and if we are suign it for auiting
14:46:30 ratailor sean-k-mooney, gibi could you please review this patch https://review.opendev.org/c/openstack/nova/+/928933 and let me know why api-samples tests are failing, I assume something is missing, but not sure what ? I tried my best to find why its failing, but couldn't get any further.
14:47:05 sean-k-mooney if we look at the policy for managing flavor https://github.com/openstack/nova/blob/master/nova/policies/flavor_manage.py#L28 we use the base admin check https://github.com/openstack/nova/blob/master/nova/policies/base.py#L40 which does not check for the project id
14:47:46 sean-k-mooney admiyo: however much of our logging does expect a project id
14:47:56 admiyo policy file overrides are a fix, but not required, so I would say that case if OK. The real issue is the defaults. If the code requires a both a project ID and the Admin role, you have a problem.
14:48:36 sean-k-mooney admiyo: for context we moved them to be system scoped and undit that https://github.com/openstack/nova/commit/066e1e69d1394839a9f0bde4ca8c3a0db2d52396
14:48:37 admiyo So how do you limit who can get the ADMIN role?
14:48:52 sean-k-mooney you do that via keystone
14:49:17 sean-k-mooney a keyston admin is needed to asing an admin role to a user on a project/domian
14:49:27 admiyo From my perspective, system scoped was a mistake. I understand why they did it (to make things more obvious) but it was fighting all of the services.
14:49:52 sean-k-mooney right which is why we went back to everyting in nova being project scoped again
14:50:50 sean-k-mooney admiyo: if you have a devstack you can proably jsut create a non project scoped token iwth the admin role and call nova to see what the behaivor is
14:50:59 admiyo What I had proposed was that we mark certain projects as ADMIN projects. Thus, if you wanted to be selective about what ADMINs could perform, say, a flavor modification, you put an additional check on those operations. But they still used project scoped tokens
14:51:33 sean-k-mooney admiyo: that not a nova dicussion
14:51:53 admiyo It waws. And it was accepted way-back-why byt the Nova PTL....
14:51:59 sean-k-mooney if you give someone admin they have admin when you call nova or neutron
14:52:29 sean-k-mooney are you usign the term project to refer to openstack serivce or keystone pojects
14:52:55 admiyo No, I was specifically using it for projects. Because the APIs all required project scoped tokens
14:53:08 admiyo For keystone projects
14:53:11 dansmith admiyo: you seem to be missing a lot of context and community-wide discussion that happened in recent years...
14:53:23 admiyo and, I agreee, the name project was not the right one.
14:53:27 dansmith rehashing it with "it was agreed by the nova PTL in 2012" is not a very compelling argument in 2024
14:54:05 admiyo it was in 2018, right before the Keystone PTL changed the direction and I rage quit. But the issue still stands that if it is broken in Nova it is broken everywhere
14:54:18 admiyo and the issue was that Admin was required on a project scoped token.
14:54:40 sean-k-mooney admiyo: for what its worth there was a discussion abou thaving a maping of roles ot service endpoints
14:54:40 admiyo And elsewhere in openstack, that was required to do things that you would assume an end user could do
14:55:23 sean-k-mooney admiyo: i.e. give someone admin on the neutron api but not on others. keystone did not want to do that
14:55:57 admiyo to be clear. I was never in support of service scoped tokens. I just stepped away from the discussion after a year of my life went in to gettin a nova acceptable solution....so all I am trying to do now is confirm that you do actually have a solution, and I am...55% convinced of that right now
14:56:41 sean-k-mooney admiyo: do you have an exampel of a call to noava that required admin on a diffent service
14:57:26 admiyo Back in the day it was stuff like add/remove userse from projects and grant role assignments.
14:57:43 sean-k-mooney which are all part of keystone
14:57:53 admiyo so in keystone to assign a user to a project, you HAD to have admin, becuase one of the roles you could grant them was Admin
14:57:56 admiyo and thus.....
14:58:12 sean-k-mooney right so the manager role is proposed to be used to do that
14:58:20 sean-k-mooney a porject manager would be able ot add a user to a project
14:58:50 admiyo TO be honest, I have not tracked what was done in Cinder or Glance ever since then.
14:58:51 sean-k-mooney a domain manager would be able to create proejcts and users in there domain
14:59:08 admiyo I know that kn heat you used to need it to clean up things that were wedged....
14:59:45 sean-k-mooney again that just soudn like a bug
15:00:20 admiyo What you are saying is that a requirement in Nova dictated how all the other projects had to implement policy.
15:00:41 sean-k-mooney admiyo: no im not
15:00:51 admiyo And you then needed to audit and get agreement from all the other projects on how to fix it.
15:01:09 sean-k-mooney again please read that document
15:01:12 admiyo Yeah, you are. Because nova both required admin and that it be on a project scoped token
15:01:24 sean-k-mooney you are mising a lot of contenxt and missrepreenting what i have said
15:01:32 admiyo I have read it. And I get it, and you did get that agree ment, but I was not able to do that back in 2017
15:02:04 sean-k-mooney to be clear neutron clinder glance and most other service had simeilr objects when they spoke to operatores about there needs
15:02:43 admiyo You might notice that glance, cinder and neutron all made efforts to fix the bug
15:02:46 sean-k-mooney admiyo: your framing the histroy as if nova was the one that pushed for this change when it was our user that push back
15:03:07 sean-k-mooney admiyo: so did we and then we reverted it based on teh compuntiy change of direction
15:03:41 admiyo Now go an look at my proposal again, and realize that it still addresses the operator concern, maintains backwards compat, and fixes the bug.
15:04:02 admiyo But all that is water under the bridge. It sounds like you do have a fix.
15:04:52 admiyo If that is the case, then don't mark the bug "won't fix." because that bug is the reason why end users did not get access to openstack APIs
15:05:21 admiyo the operators could not risk it, and they wrapped it with horrible things like CLoudForms and made the APIs operator only.
15:05:45 opendevreview Amit Uniyal proposed openstack/nova stable/2024.2: Reproducer test for image property hw_architecture https://review.opendev.org/c/openstack/nova/+/932521
15:05:46 opendevreview Amit Uniyal proposed openstack/nova stable/2024.2: Libvirt: updates resource provider trait list https://review.opendev.org/c/openstack/nova/+/932522
15:05:48 admiyo But it was not a wishlist item, and it should not be marked as won't fix
15:07:10 admiyo And by the way, we should never have had domains either. And we should have kept the term tennants instead of calling them projects. Mistakes of the past....
15:08:06 sean-k-mooney admiyo: i can change it to invalid if you would liek. but what i was litrually trying ot convay by updating the bug was no one is working on changing the scope fo the admin role and its not inline wiht the projects direction
15:08:19 sean-k-mooney and by project i litraly mean openstack
15:09:18 sean-k-mooney admiyo: if you want to change the direciton you need to do that at the openstack level and change the grovernace resolution
15:10:11 admiyo Can you state that none of Novas APIs require Admin in order to perform operations that an end user needs to be able to do? To include project self maintainence like remove some resource where the owner has quit
15:10:46 sean-k-mooney as far as i am aware that has been true for at least 10 years
15:10:49 sean-k-mooney maybe more
15:10:51 admiyo That was not the case when we opened the bug, and it was a critical security issue.
15:11:22 admiyo Then you fixed it
15:11:43 sean-k-mooney in nova all end user creatable resocues are owned by teh project not the user with the sole excption of the ssh keypair
15:12:27 admiyo Yeah, let us avoid that rabbit hole
15:12:38 sean-k-mooney the reason is say at leat 10 years is i have worked on openstack since havana and i belive it was true for nova even then
15:12:52 admiyo I think that the issue I remember was flavors.
15:13:05 sean-k-mooney flavor s shoudl nto eb managebale by end users
15:13:27 admiyo And images in glance was an issue that they addressed.
15:14:11 admiyo So you can see, it was an Openstack wide issue, and you DID address it. And it certainly affected Nova.
15:15:04 admiyo BTW, the original implementation was done by termie, the solution of having admin projects was also suggested by him. I was justtrying to keep things consistent with how the main projects viewed things.
