[neutron][tempest][all] Broken CI, any job inherited from "devstack"
by Rodolfo Alonso Hernandez 06 Oct '22

06 Oct '22

Hello all: I broke the OpenStack CI (good start as Neutron PTL). I pushed [1] testing only against the Neutron CI. After making the needed changes [2], I thought any other job would be safe. I've opened [3]. The default OVN version installed in the CI, using Ubuntu 20.04, is v20.03, that is a bit old. I've proposed to bump to v21.06, extensively tested in the Neutron CI. Any tempest job from any project is inherited from this one. Once we have migrated to Ubuntu 22.04 during this cycle, we'll remove this forced OVN installation from source. Regards.

Limit Access to a Group for a Project- Openstack 13 & 17
by samir oukessou 06 Oct '22

06 Oct '22

Dears, I have a question regarding Openstack, is it possible to limit access for a user to get read only on a specific project that he can only see the instances in that project and eliminate the actions edit,start,stop or delete instance ? i have tried some tests grant *member* role only to the group but all users in the group were able to do everything with the instances thank you in advance, Samir

[nova][cinder][glance][manila][masakari][tacker][oslo] Configurable soft-delete
by Stephen Finucane 06 Oct '22

06 Oct '22

👋 I'm planning on bringing this up in the nova rooms at the PTG in a few weeks, but I'm also raising it here since this potentially affects other service projects and I can't attend all of those room :) Many projects use the concept of "soft delete" in their database models. A soft deletable model typically has two additional columns, 'deleted' and 'deleted_at'. When deleting such a model, instead of actually deleting the database row (i.e. 'DELETE FROM table WHERE condition'), we set 'deleted' to 'True' and populate the 'deleted_at' column. This is helpful for auditing purposes (e.g. you can inspect all resources ever created, even after they've been "deleted") but bad for database performance (your tables can grow without bound). To work around the performance issues, most projects implement some kind of archive or purge command that will allow operators to periodically clean up these deleted resources. However, at least in nova, we've long since come to the conclusion that soft deleting isn't as useful as initially suspected and the need to run these commands is additional work for no benefit. We've moved toward not using it for all new models. With this said, it's going to be difficult to get away from soft-delete quickly. Not only are there database migrations involved, but operators will need to rework their tooling to adapt to a new, no-soft-delete world. As such, I'd like to propose a half-way measure of making soft-delete configurable. To do this, I'd like to add a new flag in oslo.db, '[database] enable_soft_delete'. When set to 'False' anyone using the 'SoftDeleteMixin' from oslo.db would see these models hard deleted rather than soft deleted when calling 'soft_delete'. This would avoid the need for operators to run the various project-specific purge tooling. The RFC patch for this is available for review [1]. I can also do this on a project-specific basis and have proposed a similar patch for nova [2], however, doing it in oslo.db means every project that uses 'SoftDeleteMixin' in their models will get this for free. Projects that don't (glance, cinder) can switch to using this mixin and also get it for free. As noted above, I intend to discuss this in the nova room at the PTG, but I'd be interested in people's thoughts ahead of time. Do you think this is a good idea? Should we proceed with it? Perhaps there are there better ways to do this? Let me know! Cheers, Stephen [1] https://review.opendev.org/c/openstack/oslo.db/+/860407 [2] https://review.opendev.org/c/openstack/nova/+/860401

[SECURITY] Openstack Security Assessments
by jackdaw blues 06 Oct '22

06 Oct '22

Hi all, I am currently leading a team of offensive security engineers and we are trying to create a checklist for each component of Openstack in the context of Security Assessment. At the end of the day what we want to end up with is common exploitable configuration weaknesses for each component. It will be against configuration or installation mistakes that result in unintended privileges or information disclosure, etc. Patch management isn't in scope. Not the exact output, but these links can give a good idea of the contents of the security assessment we are planning (these are for AWS): http://flaws.cloud/ http://flaws2.cloud/ Has anyone had any experience regarding the topic above? If so please feel free to connect. Regardless of the experience, if you want to contribute and at mark zero just like we are, you are still welcome and we can help each other create this assessment checklist. Cheers, Asil

[nova][placement] add your PTG topics before Oct-06 please !
by Sylvain Bauza 06 Oct '22

06 Oct '22

Hi folks, as I said in the nova meeting, I'd like to create an agenda for our PTG topics. Given the PTG is in 3 weeks, please provide your topics you'd like to discuss at the PTG in [1] so I could look at them and try to provide an agenda for them. Eventually, I'd love to have most of the topics by Oct 6th as I said in the title so the agenda would be on the Friday Oct 7th. Also, if you can't be in the Nova PTG sessions for all the PTG schedule (between Tues and Fri for Nova), just add in the topic when you would like to be around. Thanks, -Sylvain [1] https://etherpad.opendev.org/p/nova-antelope-ptg

Re: Query about networking-onos for newer OpenStack releases
by Rodolfo Alonso Hernandez 06 Oct '22

06 Oct '22

Hello Aditya: If you don't have any specific requirement, I would choose one of the Neutron in-tree ML2 plugins: ML2/OVS or ML2/OVN (and ML2/SR-IOV, that can run with the other two). About which one you can choose, I won't point you to any of them. I would prefer you to review the different architectures: * OVS: https://docs.openstack.org/liberty/networking-guide/scenario-classic-ovs.ht… (this is an old but still valid document to see the different ML2/OVS deployments) * OVN: https://www.openstack.org/videos/summits/austin-2016/practical-ovn-architec… Regards.

[Keystone][Swift] Using policy.json to prohibit specific API operations by policy?
by Andrew Boring 06 Oct '22

06 Oct '22

Hi all, I'm looking to support a situation where one class of Keystone users in a given domain can create Swift containers (either within a single, dedicated project or within their own projects) but *cannot* change ACLs on those containers, while a second class of users *can* alter ACLs on their own containers. For example, User A is in the first class (defined by role) and can perform all CRUD operations, EXCEPT update pre-defined ACLmetadata on those containers. User B is in the second class and CAN update ACLs on their respecitive containers, like any other standard user. Something like this AWS policy condition ("Granting permissions to multiple accounts with added conditions") is directionally what I'm trying to achieve: https://docs.aws.amazon.com/AmazonS3/latest/userguide/example-bucket-polici… Keystone docs imply that I can create policy.json files for all services: "You can define actions for OpenStack service roles in the /etc/PROJECT/policy.yaml files. For example, define actions for Compute service roles in the /etc/nova/policy.yaml file." -https://docs.openstack.org/keystone/yoga/admin/cli-manage-projects-users-and-roles.html But I can't find any indication that Swift actually supports this. So, does Swift support the Oslo policy.json stuff, and if so, is it documented anywhere? Is it simply a "install oslo policy and add it to the pipeline in proxy-server.conf"? If not, is there another/preferred way to achieve the desired restrictions on Swift API operations by policy for a given Keystone domain? Thanks. -- Andrew Boring andrew(a)andrewboring.com
