glibc internal ABI changes and CentOS 8 Stream updates on busy systems
by Florian Weimer 26 Aug '22

26 Aug '22

We have recently been made aware that the internal ABI changes due to LD_AUDIT fixes cause processes launched concurrently during the update to crash: glibc: Upgrading to glibc-2.28-209.el8.x86_64 causes segfaults during concurrent process launch <https://bugzilla.redhat.com/show_bug.cgi?id=2119304> In glibc-2.28-211.el8, we have made the ABI changes more compatible with *older* versions (before -208), but this might cause yet another bumpy update from -209 or -210 to -211 or later. (The version ranges are slightly different for s390x; see the bug. ppc64le has a different issue caused by RPM file writing order, but no crashes.) CentOS 9 Stream should be less sensitive to these issues due to the merged libpthread/libdl. We are putting some checks into place to catch this earlier. In general, it might not be possible to avoid such issues completely, particularly on CentOS 8 Stream. The workaround is to do updates in quasi-single-user mode, with as little running on the system as possible. Thanks, Florian

RabbitMQ eats 1.6GB ram on CentOS Stream 9
by Marcin Juszkiewicz 24 Aug '22

24 Aug '22

As part of OpenStack deployments we deploy RabbitMQ. During current cycle I looked at moving from CentOS Stream 8 to 9. And RabbitMQ is a problem. When I boot CentOS Stream 9 system and then use just built 'rabbitmq' container memory use of "/usr/lib64/erlang/erts-12.3.2.2/bin/beam.smp" process goes up to 1.6GB ram: (rabbitmq)[root@kolla-cs9 /]# rabbitmq-diagnostics memory_breakdown Reporting memory breakdown on node rabbit@kolla-cs9... other_system: 1.6233 gb (68.59%) allocated_unused: 0.5164 gb (21.82%) binary: 0.1551 gb (6.55%) code: 0.0356 gb (1.51%) other_proc: 0.0184 gb (0.78%) connection_other: 0.0037 gb (0.16%) other_ets: 0.0036 gb (0.15%) queue_procs: 0.0021 gb (0.09%) plugins: 0.0021 gb (0.09%) connection_readers: 0.0021 gb (0.09%) atom: 0.0014 gb (0.06%) mgmt_db: 0.001 gb (0.04%) metrics: 8.0e-4 gb (0.03%) connection_writers: 4.0e-4 gb (0.02%) connection_channels: 4.0e-4 gb (0.02%) mnesia: 3.0e-4 gb (0.01%) msg_index: 0.0 gb (0.0%) quorum_ets: 0.0 gb (0.0%) stream_queue_procs: 0.0 gb (0.0%) stream_queue_replica_reader_procs: 0.0 gb (0.0%) queue_slave_procs: 0.0 gb (0.0%) quorum_queue_procs: 0.0 gb (0.0%) stream_queue_coordinator_procs: 0.0 gb (0.0%) reserved_unallocated: 0.0 gb (0.0%) If I boot the same container on Debian host then same process uses 0.2GB ram: (rabbitmq)[root@debian /]# rabbitmq-diagnostics memory_breakdown Reporting memory breakdown on node rabbit@debian... binary: 0.2787 gb (70.2%) code: 0.0355 gb (8.93%) other_system: 0.0255 gb (6.44%) other_proc: 0.0209 gb (5.26%) connection_other: 0.0108 gb (2.72%) mgmt_db: 0.0073 gb (1.84%) plugins: 0.0048 gb (1.2%) other_ets: 0.0037 gb (0.93%) connection_readers: 0.003 gb (0.75%) queue_procs: 0.0028 gb (0.7%) atom: 0.0015 gb (0.37%) metrics: 0.0011 gb (0.28%) connection_channels: 8.0e-4 gb (0.21%) mnesia: 4.0e-4 gb (0.1%) connection_writers: 2.0e-4 gb (0.05%) msg_index: 0.0 gb (0.01%) quorum_ets: 0.0 gb (0.01%) stream_queue_procs: 0.0 gb (0.0%) stream_queue_replica_reader_procs: 0.0 gb (0.0%) queue_slave_procs: 0.0 gb (0.0%) quorum_queue_procs: 0.0 gb (0.0%) stream_queue_coordinator_procs: 0.0 gb (0.0%) allocated_unused: 0.0 gb (0.0%) reserved_unallocated: 0.0 gb (0.0%) So I started checking. Maybe it is a problem of Erlang/RabbitMQ packages provided by RabbitMQ team? Booted CS9 system and deployed OpenStack using Debian based containers. Again 1.6GB memory use. So let build CS9 based containers using Erlang/RabbitMQ from CentOS Stream 9 "messaging/rabbitmq-38" repository. Again 1.6GB memory use. I am wondering what is a reason? And what is proper solution? For now I only know not-acceptable solution: deploy OpenStack using Debian or Ubuntu and forget about CentOS Stream 9 and rest of RHEL 9 family.

CPE Weekly Update – Week 33 2022
by Michal Konecny 19 Aug '22

19 Aug '22

Hi everyone, This is a weekly report from the CPE (Community Platform Engineering) Team. If you have any questions or feedback, please respond to this report or contact us on #redhat-cpe channel on libera.chat (https://libera.chat/). Week: 15th August - 19th August 2022 If you wish to read this in form of a blog post, check the post on Fedora community blog: https://communityblog.fedoraproject.org/cpe-weekly-update---week-33-2022/ # Highlights of the week ## Infrastructure & Release Engineering Goal of this Initiative ----------------------- Purpose of this team is to take care of day to day business regarding CentOS and Fedora Infrastructure and Fedora release engineering work. It’s responsible for services running in Fedora and CentOS infrastructure and preparing things for the new Fedora release (mirrors, mass branching, new namespaces etc.). The ARC (which is a subset of the team) investigates possible initiatives that CPE might take on. Link to planning board: https://zlopez.fedorapeople.org/I&R-2022-08-17.pdf Link to docs: https://docs.fedoraproject.org/en-US/infra/ Update ------ ### Fedora Infra * Mass update/reboot cycle this week (stg/nonoutage done, outage later today) * Freeze for f37 beta starts next week ### CentOS Infra including CentOS CI * Discussion around the CentOS Stream infra hand over * New tasks for the CI infra migration * S3 bucket for the Stream CoreOS effort * Some infra projects moved from gitea to gitlab ### Release Engineering * Openh264 composes fo f36,37,38 send to cisco * Package retirement issues after the branching, thanks to human error ## CentOS Stream Goal of this Initiative ----------------------- This initiative is working on CentOS Stream/Emerging RHEL to make this new distribution a reality. The goal of this initiative is to prepare the ecosystem for the new CentOS Stream. Updates ------- * Face to face meeting in Boston. * Penultimate parts of Module process sync. Between el8 and el9. ## EPEL Goal of this initiative ----------------------- Extra Packages for Enterprise Linux (or EPEL) is a Fedora Special Interest Group that creates, maintains, and manages a high quality set of additional packages for Enterprise Linux, including, but not limited to, Red Hat Enterprise Linux (RHEL), CentOS and Scientific Linux (SL), Oracle Linux (OL). EPEL packages are usually based on their Fedora counterparts and will never conflict with or replace packages in the base Enterprise Linux distributions. EPEL uses much of the same infrastructure as Fedora, including buildsystem, bugzilla instance, updates manager, mirror manager and more. Updates ------- * EPEL9 is up to 7339 (+106) packages from 3278 (+71) source packages * Found the bloaty package was uninstallable because of a libre2 soname fix, rebuilding it fixed the issue. ## FMN replacement Goal of this initiative ----------------------- FMN (Fedora-Messaging-Notification) is a web application allowing users to create filters on messages sent to (currently) fedmsg and forward these as notifications on to email or IRC. The goal of the initiative is mainly to add fedora-messaging schemas, create a new UI for a better user experience and create a new service to triage incoming messages to reduce the current message delivery lag problem. Community will profit from speedier notifications based on own preferences (IRC, Matrix, Email), unified fedora project to one message service and human-readable results in Datagrepper. Also, CPE tech debt will be significantly reduced by dropping the maintenance of fedmsg altogether. Updates ------- * Frontend * Use CoreUI components * Set up i18n * Initial version of a “New Rule” page * Authentication integration FE/BE (ongoing) * Backend: SQLAlchemy integration (ongoing)) Kindest regards, CPE Team

Changes to CentOS CI: reminder of Phase 1 and 2
by Camila Granella 16 Aug '22

16 Aug '22

Hello everyone, This is a friendly reminder of the current and upcoming status of CentOS CI changes (check [1]). Projects that opted-in for continuing on CentOS CI have been migrated, and the new Duffy API is available. With that, *phase 0 has been completed*. Regarding *phase 1*, we are still working on a permanent fix for the DB Concurrency issues [2]. Also, as for our OpenShift new deployment, we have a staging environment up and running, and it should be available at the beginning of September 2022. In October 2022 we begin *phase 2* when we will work through the following items (these were also previously communicated in [1]): - legacy/compatibility API endpoint will handover EC2 instances instead of local seamicro nodes (VMs vs bare metal) - bare-metal options will be available through the new API only - legacy seamicro and aarch64/ThunderX hardware are decommissioned - only remaining "on-premises" option is ppc64le (local cloud)Feel free to reach out if you have any questions or concerns The final deadline for decommissioning the old infrastructure (*phase 3*) is *December 2022*. We will be communicating further until then, and meanwhile, reach out to any of us in case you have any questions. Regards, [1] [ci-users] Changes on CentOS CI and next steps: https://lists.centos.org/pipermail/ci-users/2022-June/004547.html [2] DB Concurrency issues: https://github.com/CentOS/duffy/issues/523 -- Camila Granella Associate Manager, Software Engineering Red Hat <https://www.redhat.com/> @Red Hat <https://twitter.com/redhat> Red Hat <https://www.linkedin.com/company/red-hat> Red Hat <https://www.facebook.com/RedHatInc> <https://www.redhat.com/>

infra outage : Stream 9 builsystem
by Fabian Arrotin 11 Aug '22

11 Aug '22

Hi, We got some monitoring alerts that CentOS Stream 9 build infra is actually unreachable. We have an internal ticket open at Red Hat to investigate the issue (seems network related) If you're directly consuming pkgs from that infra (like https://kojihub.stream.centos.org) it's actually unreachable. That means that it also impacts downstream buildsystems, like https://cbs.centos.org, but only if you asked to consume directly pkgs from teh CentOS Stream 9 buildroot. For SIGs only building against content from mirror.stream.centos.org, builds should continue to work. We'll update this thread when we'll have more information. -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | twitter: @arrfab
