Latest CentOS Stream 8 kernel package?
by Bussi Andrea 25 Nov '22

25 Nov '22

My CentOS Stream 8 machines have: kernel-4.18.0-408.el8.x86_64 as the most recent kernel package. (Top of the changelog: * Wed Jul 06 2022 Jarod Wilson <jarod(a)redhat.com> [4.18.0-408.el8] - powerpc/smp: Set numa node before updating mask (Diego Domingos) [2103833] - iommu/vt-d: Fix potential memory leak in intel_setup_irq_remapping() (Mohammed Gamal) [2088366] - irqdomain/treewide: Free firmware node after domain removal (Mohammed Gamal) [2088366] - x86/kvmclock: Fix Hyper-V Isolated VM's boot issue when vCPUs > 64 (Mohammed Gamal) [2088366] - x86/kvm: Don't waste memory if kvmclock is disabled (Mohammed Gamal) [2088366] - x86/pci: Create PCI/MSI irqdomain after x86_init.pci.arch_init() (Mohammed Gamal) [2088366] ) But, being released in July, it's a bit old and surely missing some fixes and security patches. I was wondering if that is the last released kernel package, or if there's something wrong with my machines. I could not find a more recent kernel package, but maybe I'm not looking in the right places. I tried: https://composes.centos.org/ https://git.centos.org/rpms/kernel/commits/c8s https://gitlab.com/redhat/centos-stream/rpms/kernel/-/tree/c8s https://koji.mbox.centos.org/koji/packageinfo?packageID=866 For comparison, my AlmaLinux 8 machines have: kernel-4.18.0-425.3.1.el8 (Top of the changelog: * Fri Sep 30 2022 Jarod Wilson <jarod(a)redhat.com> [4.18.0-425.3.1.el8] - iwlwifi: limit fw version for AC9560 to avoid fw crash (<C3><8D><C3><B1>igo Huguet) [2129297] - sfc: fix null pointer dereference in efx_hard_start_xmit (<C3><8D><C3><B1>igo Huguet) [2119638] - sfc: fix TX channel offset when using legacy interrupts (<C3><8D><C3><B1>igo Huguet) [2119638] - netfilter: conntrack: reduce timeout when receiving out-of-window fin or rst (Florian Westphal) [2047366] - netfilter: conntrack: remove unneeded indent level (Florian Westphal) [2047366] - netfilter: conntrack: ignore overly delayed tcp packets (Florian Westphal) [2047366] ) Thanks, Andrea

Hi everyone, We are excited to announce that Anaconda Web UI preview image mentioned by Fedora change[0] is now public for testing and providing feedback. You can find more information here: https://fedoramagazine.org/anaconda-web-ui-preview-image-now-public Feel free to download the ISO, test it and please provide us feedback as written in the article. Please note, we are now fixing size of the ISO (it has 7 GB because of the problem with a build of ISO), hopefully it should be resolved soon.

New glibc DSO dependency sorter is coming to CentOS 8 Stream
by Florian Weimer 22 Nov '22

22 Nov '22

We have a glibc build unter test (glibc-2.28-221.el8) that switches the DSO dependency sorter to the current upstream version. It's already part of CentOS 9 Stream (and was introduced into Fedora 35 in January this year). The dependency sorter determines the order in which ELF shared objects are initialized, and in case of multiple shared objects providing the same symbol, which symbol definition is chosen for the process. The old dependency sorter exhibits very bad performance with certain dependency graphs. For example, some users have reported significant delays during process exit after many shared objects have been opened using dlopen. The old and new algorithm do not necessarily produce the same results in all cases if cycles are involved (which means that there is no one true solution to the initialization order problem). This means that there is a possiblity of an observable behavioral difference, although we have not received any reports that this causes problems. Thanks, Florian

Changes to CentOS CI: reminder of Phase 3 and update on OpenShift new instance
by Camila Granella 17 Nov '22

17 Nov '22

Hello everyone, This is a friendly reminder of CentOS CI changes' current status and upcoming action items (check [0]) in addition to a quick update on our new OpenShift instance. According to our previous communications [0], we are approaching the last phase of the changes that have been implemented to CentOS CI. We are currently closing phase 2, which began in October. In December, we will move to *phase 3*: *Phase 3 - Decommission* - Legacy/compatibility API deprecated and requests (even for EC2 instances) will no longer be accepted - All tenants that opted in will be using only EC2 for aarch64/x86_64 and on-premise cloud for ppc64le For a full description of the project phases, you can check [0]. Currently, our Infra & Releng team is working to deploy our new OpenShift instance (AWS) in production after some improvements that have been done in staging. When OpenShift gets fully set up, the team will work to migrate the Pagure project. This will then be documented and passed on to you (users) as a guide in order to *facilitate the workload migration that is expected to be done on your side*. We are expecting this to be completed by the end of the year. We will be sharing further information on this at the beginning of Q1CY2023. A reasonable timeline will be provided so that you have enough bandwidth to work on the migration of your workloads. Please, feel free to reach out to us in case you have any questions or concerns.

The call for proposals is now open. ## About the Distributions Devroom The Distributions Devroom is run by and for the people who build, package, and contribute to distributions of Linux and other software. Distributions remain a critical part of modern IT infrastructure, whether running on bare metal or in containers, from supercomputers to edge deployments.

Register a FOSDEM Pentabarf account[1] and sign in. 2. Visit the FOSDEM CFP[2] and click "Create Event". 3. Make sure "Track" is set to "Distributions devroom" for wranglers to receive your submission! 4. Complete the form with your presentation details.

Every year, thousands of developers of free and open source software from all over the world gather at the event in Brussels. FOSDEM hosts dozens of developer rooms, where community members run tracks on various topics. -- Thanks, Shaun McCance CentOS Community Architect

[CentOS Stream Infra] - Planned outage : koji build infra
by Fabian Arrotin 15 Nov '22

15 Nov '22

Due to a needed koji upgrade (from 1.26 to 1.30) and also various renewed TLS certificates rollout, we'll have to temporary freeze the CentOS Stream build environment and/or restart some services/api endpoints Impacted services: - https://kojihub.stream.centos.org (all services, also for mbs/odcs) - https://sources.stream.centos.org (lookaside cache server) Migration is scheduled for """"Friday November 25th, 1:30 pm UTC time"""". You can convert to local time with $(date -d '2022-11-25 13:30 UTC') The expected "downtime" is estimated to 30 minutes, time needed to : - stop kojihub and backup database - kojihub is upgraded by ansible role and postgresql db schema update to correct version - kojid builders are then also upgraded by ansible role You can also join us in either #centos-devel or #centos-stream irc channels on irc.libera.chat if you encounter any issue. Thanks for your understanding and patience. on behalf of the CentOS Stream Infra team, -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | twitter: @arrfab

Alternative Images SIG - meeting time survey
by Troy Dawson 14 Nov '22

14 Nov '22

I have created a poll to help us figure out the best day and time to have our meetings. I did the times a bit to the extreme, from very very early for those on the U.S. west coast, to very very late for those in Europe. I sorta hope neither of those extremes are picked, but I figured it would be best to have everything. I have setup the poll for Monday through Friday. Just ignore the dates (14-18) associated with them. Here is the link. https://framadate.org/49adIbSCsZhmbjqm Troy Dawson
