The present model for openstack API services uses keystone for authentication mechanism for the REST API. is it possible to test the api calls directly using the server/port of a API service, bypassing the keystone URI ? does this require any modification in the configuration of the openstack service ? Thanks

[neutron] Using address scopes in a DVR environment breaks floating IPs
by Lukas Steiner 17 Jan '25

17 Jan '25

Hi all, I hope to get some advice here if we’re doing something wrong or ran into a bug. We have an OpenStack environment (wallaby) with Distributed Virtual Router (DVR) enabled (compute nodes use DVR_NO_EXTERNAL agent mode, network nodes use DVR_SNAT) and we would like to onboard our provider network to a subnet pool part of an address scope to allow routed self-service networks. But as soon as the provider network is part of an address scope, the floating IP feature stops working. After debugging we found that adding the network to an address scope results in an additional set of firewall rules in the router and snat network namespaces which blocks cross-scope traffic. But floating IPs should be the exception to that and there are indeed rules that explicitly allow them by setting a mark in the iptables mangle table: -A neutron-l3-agent-floatingip -d <floating-ip>/32 -i qg-<random-id> -j MARK --set-xmark 0x4000000/0xffff0000 We can find these rules in the qrouter namespaces, but they’re missing in the snat namespaces. If we add the rule manually to the snat namespace, the floating IP is working again. If we switch the compute nodes to DVR agent mode, it also works, as the snat namespace is not used. I have already searched for bugs and changes in the DVR router code since wallaby but can’t find anything which is not already patched in wallaby. So, I’m wondering if we have an unsupported setup with combining dynamic routing with DVR and centralized network nodes or facing a long running neutron bug. Maybe someone has a similar setup or can confirm that this use case should be supported? Regards, Lukas

Re: Dalmatian Devstack: Empty Port Binding section in Horizon
by Lajos Katona 17 Jan '25

Hi, I checked and I hoped that this SDK patch : https://review.opendev.org/c/openstack/openstacksdk/+/915902 or SDK 4.2.0 is enough (for binding details at least) but something else is missing. Could you please open a bug report for this issue, I try to check where to fix it.

Adding a compute node using Openstack ansible
by Derek O keeffe 16 Jan '25

16 Jan '25

Hi all, I have something weird happening when trying to add a compute node to a working cluster. I added "compute3" to my openstack_user_config.yml compute_hosts stanza and ran the setup_hosts playbook. This created (re-created) the openstack_inventory.json file which I have reviewed thoroughly and I can see compute3 added everywhere compute1 and compute2 had been added from the deploy. When I run the second playbook setup_infrastructure, all the plays skip saying "no hosts matched" but the tasks all touch compute3.... I ran /opt/openstack-ansible/scripts/inventory-manage.py -G and I can see my compute3 listed in the output. The commands I run for the playbooks are as follows: openstack-ansible setup-hosts.yml --limit ,compute3openstack-ansible setup-infrastructure.yml --limit ,compute3openstack-ansible setup-openstack.yml --limit ,compute3 I've been trying to solve this since before Christmas with no luck, could anyone please shed some light on what the issue could be? Output of first playbook: https://paste.openstack.org/show/blArG04q6wgUCJy9JPh3/Output of second playbook: Paste #bSiabwqOk7qdns2iBYDA | LodgeIt! | | | | Paste #bSiabwqOk7qdns2iBYDA | LodgeIt! | | | Any advice or info would be greatly appreciated.

[kolla-ansible][keystone]problem using LDAP and TLS
by Franck VEDEL 15 Jan '25

15 Jan '25

Hello, with all previous versions, to authenticate users from an Active Directory domain, using an LDAP connector worked without any problem on my labs, with or without using TLS. With TLS the file used is the following: /etc/kolla/config/keystone/domains/keystone.DOM1.conf [identity] driver = ldap [ldap] url = ldap://172.16.60.41 user = CN=ldapconnect,OU=openstack,DC=dom1,DC=loc password = XXXXXXXXXX suffix = DC=dom1,DC=loc user_tree_dn = OU=openstack,DC=dom1,DC=loc user_objectclass = person user_filter = (|(memberOf=CN=openstack-users,OU=openstack,DC=dom1,DC=loc)(memberOf=CN=openstack-admins,OU=openstack,DC=dom1,DC=loc)) user_id_attribute = sAMAccountName user_name_attribute = sAMAccountName user_mail_attribute = mail user_pass_attribute = user_enabled_attribute = userAccountControl user_enabled_mask = 2 user_enabled_default = 512 user_attribute_ignore = password,tenant_id,tenants group_objectclass = group group_tree_dn = OU=openstack,DC=dom1,DC=loc group_filter = (|(CN=openstack-users)(CN=openstack-admins)) group_id_attribute = cn group_name_attribute = name query_scope = sub chase_referrals = false use_tls = True tls_certificate = /etc/kolla/certificates/adserv.crt tls_req_cert = never I want to see if it works with Dalmatian (to update my lab, which I can't do with the Bobcat and Caracal versions because bugs block me). Without TLS (use_tls = False) , no problem, it works, my AD users can use Horizon and have access to their project. If I put "use_tls = True" and tls_certificate = /etc/kolla/certificates/adserv.crt .... It doesn't work with Dalmatian, certificate problem. Indeed, the certificate is not copied into the keystone container, so it can't use it. In the keystone logs (/var/kolla/keystone/keystone.log) there is an error message: 2025-01-15 08:36:04.477 1084 ERROR keystone.server.flask.request_processing.middleware.auth_context OSError: tls_cacertfile /etc/kolla/certificates/adserv.crt not found or is not a file However, my adserv.crt file has not changed, is valid, and is in /etc/kolla/certificates directory. What could have changed with the Dalmatian version? I tried to change parameters, but I can't find the solution. How should I proceed to make it work with TLS. I specify again that it works without TLS so the problem is really to use this certificate correctly, so to put it in the right place with the right parameter: tls_certificate or a new one? My lab use ubuntu 2204. Thanks a lot for your help Franck VEDEL

[dev] Invitation to participate in a survey on flaky tests spanning multiple OpenStack projects
by xiao＠ait.kyushu-u.ac.jp 15 Jan '25

15 Jan '25

Hello there, My name is Tao Xiao, Assistant Professor at Kyushu University (Japan), and togather with a team from Canada and China. Our research specifically investigates cross-project flakiness by analyzing information available on the Gerrit Code Review platform. Through our study, we have observed a significant number of flaky tests spanning multiple OpenStack projects and categorized several potential causes behind this phenomenon. Our next step is to validate our empirical findings and gather real developers' perceptions to improve the OpenStack ecosystem through a developer survey. If you have at most 10 minutes, we have designed a simple survey to capture your perceptions. The survey link is here: https://forms.gle/dUMWRL8MNALQE6kG8 This questionnaire is totally anonymized, and the survey was approved by the Kyushu University, Japan ethics board (2024-26). Again, thank you so much for your time, and please feel free to contact us for more information.
