[all][elections][tc] TC Election Campaigning Kickoff
by Ian Y. Choi 20 Aug '25

20 Aug '25

Developers, The TC Election Campaigning Period has now started[1]. During the next couple days, you are all encouraged to ask the candidates questions about their platforms[2], opinions on OpenStack, community governance, and anything else that will help you to better determine how you will vote. This is the time to raise any issues you wish the future TC to consider, and to evaluate the opinions of the nominees prior to their election. Candidates, Each of you has posted a platform[2], and announced your nomination to the developers. From this point, you are encouraged to ask each other questions about the posted platforms, and begin discussion of any points that you feel are particularly important during the next cycle. While you are not yet TC members, your voices and opinions about the issues raised in your platforms and questions raised by the wider community will help ensure that the future TC has the widest possible input on the matters of community concern, and the electorate has the best information to determine the ideal TC composition to address these and other issues that may arise. [1] https://governance.openstack.org/election/ [2] https://opendev.org/openstack/election/src/branch/master/candidates/2026.1/… Ian Y. Choi & Slawek Kaplonski, on behalf of election officials.

OSSN-0094: Ensuring Volume Safety with Nova and Watcher
by Jay Faulkner 20 Aug '25

20 Aug '25

OSSN-0094: Ensuring Volume Safety with Nova and Watcher == Summary == A vulnerability has been identified in OpenStack Nova and OpenStack Watcher in conjunction with volume swap operations performed by the Watcher service. Under specific circumstances, this can lead to a situation where two Nova libvirt instances could reference the same block device, allowing accidental information disclosure to the unauthorized instance. == Affected Services / Software == Services: Nova,Watcher Releases: all supported releases == Discussion == The issue occurs when Watcher's zone migration strategy performs the following sequence of events: 1. Watcher initiates a volume swap using Nova's internal-only volume swap API 2. Watcher initiates a live migration of the same instance 3. In some error cases connection details may have failed to update storage references. These invalid details are used during the live migration. === Required Access === The swap volume, live migration and all Watcher APIs are admin only so with default policy is only possible to create the inconsistent state described in this OSSN if you have admin rights on the relevant OpenStack project. === Further Watcher Hardening === The Watcher service, when first created, often implemented its own means to perform operations. Many of those operations can now be done natively via other OpenStack services. In the specific context of OSSN-0094, the ability to migrate Cinder volumes between storage backends is such an example. Additionally, the Cinder volume migration in Watcher created a new Keystone user with the admin role assigned for the instance owners' project and then used that user to perform API requests on behalf of the project. This code has been removed. Finally, due to limited error handling and no validation that the objects involved were migrated properly, some error scenarios could have led to a source volume being deleted despite not having been migrated properly. === Resolution === Nova will now reject any request to swap a volume that has an empty migration status, effectively restricting the usage of this API to Cinder. This brings the API validation in line with the documentation. Watchers internal implementation of swap volume has been deleted and updated to use Cinder's native volume migration as a replacement. Watcher no longer creates temporary Keystone users in normal operation. === Patches === Patches for Nova and Watcher have been backported to all supported stable branches and committed to master branch. stable/2025.1: * Watcher: https://review.opendev.org/c/openstack/watcher/+/957770 * Nova: https://review.opendev.org/c/openstack/nova/+/957759 stable/2024.2: * Watcher: https://review.opendev.org/c/openstack/watcher/+/957773 * Nova: https://review.opendev.org/c/openstack/nova/+/957762 stable/2024.1: * Watcher: https://review.opendev.org/c/openstack/watcher/+/957774 * Nova: https://review.opendev.org/c/openstack/nova/+/957764 == Recommended Actions == * Operators using Watcher's zone migration strategy should apply the provided Watcher and Nova patches as soon as possible. * Operators should refrain from using the swap volume migration action in Watcher. The compatibility code for swap volume that uses a Cinder-based migration may be removed in a future API version. * Operators should audit all users with the admin role and ensure no temporary Watcher-created users remain. * Operators using custom policy for volume attachment (''/servers/{server_id}/os-volume_attachments/{volume_id}'') or live migration API should review the state of existing instances which have had volume migrations. Any instance in an inconsistent state can be resolved by hard rebooting the instance using Nova's API. == Contacts / References == * Author: Sean Mooney <smooney(a)redhat.com>, Jay Faulkner <jay(a)jvf.cc> * This OSSN : https://wiki.openstack.org/wiki/OSSN/OSSN-0094 * Original LaunchPad Bug : https://bugs.launchpad.net/nova/+bug/2112187 * Mailing List : [Security] tag on openstack-discuss(a)lists.openstack.org * OpenStack Security Project : https://launchpad.net/~openstack-ossg * CVE: None

[vitrage][tc] Project status
by Takashi Kajinami 20 Aug '25

20 Aug '25

Hi, Some of you might be aware of this, but tempest jobs in vitrage repo have been broken for some time (I remember I saw consistent failures early in this cycle and I'm afraid that the situation hasn't been improved.) I spent some time to dig into these failures and found out a few problems. However I'm afraid I can't fix these all with my limited knowledge about vitrage. # I've helped its project maintenance for some time but I've never looked into # its implementations quite in detail. So I'm sharing my observations here hoping someone who know better about it can look into these. 1. Usage of removed oslo_context.context.RequestContext interfaces This is the most trivial and can be fixed easily. https://review.opendev.org/c/openstack/vitrage/+/957004/2/vitrage/api/hooks… 2. Usage of asyncore modules from pysnmp-lextudio Recent release of pysnmp-lextudio no longer provides these modules, likely due to removal of asyncore in Python 3.12 . I was drafting the migration to asyncio version in https://review.opendev.org/c/openstack/vitrage/+/957004 but learned simple replacement does not work and we need more careful assessment. This might be the most tricky problem atm. 3. Some tempest test failures I can no longer see old CI results, but as far as I'm aware, CI jobs were blocked by a few tests consistently failing early in this cycle so we may have to dig into these, too. You may find some tempest tests failures in https://review.opendev.org/c/openstack/vitrage/+/957004 though I'm unsure if these are related to broken snmp service, which is caused by incomplete migration to asyncio (which I described in 2). I'm adding the tc tag, to notify them of the current status. Thank you, Takashi Kajinami -- Takashi Kajinami irc: tkajinam github: https://github.com/kajinamit launchpad: https://launchpad.net/~kajinamit

[swift] Unmaintained branch cleanup
by Tim Burke 20 Aug '25

20 Aug '25

Swift currently has six unmaintained branches: - unmaintained/2023.1 - unmaintained/zed - unmaintained/yoga - unmaintained/xena - unmaintained/wallaby - unmaintained/victoria Half of them have not been updated this year. For all of them, the only patches since the transition to unmaintained status were to try to maintain CI. While two of them have open patches, they all seem to revolve around maintaining CI and none of them currently pass. I propose transitioning all of these to end-of-life. If you have any objections, please respond here on the mailing list or at https://review.opendev.org/c/openstack/releases/+/958101 which makes the change. Tim

[masakari] Add a rpc api for ping check
by do-gyun kim 20 Aug '25

20 Aug '25

Similar to Nova, I think it would be good to add ping api to masakari engine for rpc health check. This can be used for reading business and lifestyle check in Masakari distributed to Kubernetes through OpenStack Helm. Currently, there is no health check for masakari-engine in openstack-helm project, but it would be good to add it. Blueprint: https://blueprints.launchpad.net/masakari/+spec/add-a-rpc-api-for-ping

[openstack-client|keystone] API calling behavior for fetching by id or name
by Niklas Schwarz 19 Aug '25

19 Aug '25

Hey there I have observed that the keystone logs are flooded with error messages and a stack trace that resources are not found. When investigating on the issue I noticed that the resources do exist but the behavior of the openstack-client is a bit confusing. I will describe the behavior for the openstack-client in the interaction with the kestone api. As know the openstack-cli which uses the openstack-client has the functionality to show a user either by passing an id or the name of the user. The requests when executing the command with the name of the user will be 1. v3/user/<name_or_id> - v3/user?name=<name_or_id> The first request is issued to the endpoint which expects the rout parameter to be an id of the user and in the case of the keystone api a db query is executed with the name as an id and no user will be found which results in the log message and the stack trace in the keyston logs. Because no user was found the openstack-client issues a second request to the api with the name as a query-parameter instead of a rout-parameter which will issue the db-query at the keystone api to search by the username. On some deployments this can and will be additional load on the database and on the api which can be reduced just by sending the correct request to the api instead of "guessing" and trying for the correct request and hoping there will be an answer. The issue with keystone is that the openstack-client will issue also requests to the keystone api when listing, e.g. networks but only for a specific project (openstack network list --project <name_or_id>). The client will first search for the project and in the worst case these are two requests. In my opinion this behavior can be prevented to send multiple requests to the keystone api (or any other api), either by checking on the client if a the passed parameter is an id or by handling the passed route-parameter accordingly in the keystone api and executing the correct db-query to prevent multiple requests. I have decided on implementing a change [1] on the client side and have adjusted the openstack-client. As artem pointed out in the review that in some services there are places where the id cannot be really identified as such I wanted to ask/I was asked to discuss the issue on the mailing list since there might be multiple projects involved in such a change to reduce the calls to the api (when handling on the client side) or db (when handling on the server side) when a search by an id or name is issued. Are there an plans on tackling this issue or any other options and opinions? The post by marc [2] might also be a result of the openstack-client issuing multiple requests to the api and polluting the logs. So in some cases this is a realy issue.
