CentOS Connect

CentOS Connect has been announced as a FOSDEM Fringe event. This free event takes place in Brussels on February 3, 2023, the day before FOSDEM. If you’re attending FOSDEM, join us at CentOS Connect to learn about CentOS and connect with the people who work on it.

Alternate Images SIG

The Alternate Images SIG has officially been launched to provide additional operating system images, such as live media and alternate installations. Their meetings happen weekly on Thursdays at 1900 UTC in the #centos-meeting IRC channel.

OKD Streams

The OKD project has announced OKD Streams, stable OKD builds on the newly introduced CentOS Stream CoreOS. OKD is the community distribution of Kubernetes that powers Red Hat OpenShift.

SIG Reports

Each month, we publish a rotating selection of quarterly reports from our Special Interest Groups. This month includes reports from the Cloud, Promo, and Storage SIGs.

Cloud

Purpose

Packaging and maintaining different FOSS based Private cloud infrastructure applications that one can install and run natively on CentOS.

https://wiki.centos.org/SpecialInterestGroup/Cloud

Membership update

Continue to aid OKD and SCOS in onboarding into the community. OKD maintainer Christian Glombek will fill the vacant CloudSIG co-chair position.

Releases in the most recent quarter (or most recent release, if none in that quarter)

CloudSIG has published the RDO Zed release based on upstream OpenStack Zed. (https://lists.centos.org/pipermail/centos-devel/2022-November/120679.html)

The OKD Working Group has published the first OKD/SCOS (OKD on CentOS Stream CoreOS) MVP release in collaboration with the CloudSIG. (https://cloud.redhat.com/blog/okd-streams-building-the-next-generation-of-okd-together)

Health and activity

The Cloud SIG remains fairly healthy. And is still looking for other projects to join to expand it’s audience.

Promo

In August, we put on a Dojo at DevConf.US. This was our first return to in-person events. We also allowed virtual participation. The event went well overall, and has potential for future growth. Read the full event report.

We have been working on planning CentOS Connect at FOSDEM. CentOS Connect is a rebranding of CentOS Dojos. In the past, our FOSDEM Dojos have been our largest by far. We are planning for 100 people for a single-day event. This is smaller and shorter than pre-pandemic events.

Finally, a group from China has formally joined the Promo SIG to work on regional and localized outreach and promotion. We’re excited about the work they’re already doing, and we hope this paves the way for more regional promotion activities down the line.

Storage

Package updates since the last report:

  • Glusterfs 10 updated to glusterfs-10.3, packages are available for Stream 9 and Stream 8.
  • Glusterfs 9, updated to glusterfs-9.6, packages are available for Stream 9, Stream 8, and CentOS 7.
  • Ceph Quincy (17) updated to ceph-17.2.5, packages are available for Stream 9 and Stream 8.

Modularity in EPEL 8

The EPEL team is retiring package modularity in EPEL 8. Modules were introduced in RHEL 8, but have since been phased out. They were never supported in EPEL 9.

Keylime Changes

The Keylime team has announced th new versions of keylime and keylime-agent-rust will include major changes in their configuration files. These changes are intended to ease future upgrades and to make the TLS setup more consistent.

SIG Reports

Each month, we publish a rotating selection of quarterly reports from our Special Interest Groups. This month includes reports from the Automotive, Hyperscale, and Kmods SIGs.

Automotive SIG

The AutomotivE SIG has posted their quarterly report on the mailing list.

Hyperscale SIG

The Hyperscale SIG has posted their quarterly report on the CentOS blog.

Kmods SIG

This report covers work that happened since last report. The previous report can be found here.

Purpose

Packaging and maintaining kernel modules for CentOS Stream and Enterprise Linux.

Membership Update

No SIG members have been added since last report. We welcome anybody that’s interested and willing to do work within the scope of the SIG to join and contribute.

Support for CentOS Stream 9 / EL9

The Kmods SIG provides packages for CentOS Stream 9 and EL9.

Support for CentOS Stream 8 / EL8

The Kmods SIG continues to provide packages for CentOS Stream 8 and EL8.

New Packages

See Kmods SIG’s documentation for lists of available packages. This documentation also provides further information, e.g. how to enable the Kmods SIG’s repositories.

Note that the kernel modules provided by the Kmods SIG are currently not signed with a private key. Hence it is required to disable Secure Boot to be able to use any of these kernel modules.

Please report any issues with these packages in the corresponding project on gitlab.com/CentOS/kmods or here in case the issue is not related to a particular package.

Recent Activities

The Kmods SIG has moved all of its resources to gitlab.com/CentOS/kmods. This includes all tooling to automatically detect required kernel module rebuilds due to kABI changes. We rely on GitLab CI for these kind of tasks.

Thanks to work done by the CentOS Infrastructure team there is now automatically created a Driver Disk for any kernel module released by the Kmods, or any other, SIG.

Health and Activity

The Kmods SIG maintains a healthy development pace.

Communication

Regular meetings are scheduled monthly, in the first week, on Monday at 1600 UTC in #centos-meeting. Everyone is welcome to join!

You can also get in touch with SIG members at any time in #centos-kmods.

Open Issues

  • Signing kernel modules: This requires collaboration and further discussion with Infra SIG. Especially about how to securely store a SIG specific key that can be used in CBS, but is not accessible by any unauthorized person.

  • Release packages for EL: The SIG would like to provide release packages to allow users running RHEL, or one of its clones, to easily access packages provided by the SIG. The current state can be tracked here.

Issues for the Board

We have no new issues to bring to the board’s attention at this time.

CPE Quarterly Update Q3 2022

October 26, 2022 07:59 AM

This is a summary of the work done on initiatives by the CPE Team. Each quarter CPE Team together with CentOS and Fedora community representatives chooses initiatives that will be worked on in this quarter. The CPE Team is then split into multiple smaller sub-teams that will work on chosen initiatives + day to day work that needs to be done.

This update is made from infographics and detailed updates. If you want to just see what’s new, check the infographics. If you want more details, continue reading.

Infra & Releng

About

The purpose of this sub-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.). This sub-team is also investigating possible initiatives. This is done by ARC (The Advance Reconnaissance Crew), which is formed from the Infra & Releng sub-team members based on the initiative that is being investigated.

CentOS Hyperscale SIG Quarterly Report for 2022Q3

October 03, 2022 04:28 PM

CentOS Hyperscale SIG Quarterly Report for 2022Q3

This report covers work that happened between July 5th and September 30th. For previous work, see the 2022Q2 report.

Purpose

The Hyperscale SIG focuses on enabling CentOS Stream deployment on large-scale infrastructures and facilitating collaboration on packages and tooling.

Membership update

Since the last update, the SIG gained two new members (Quentin Deslandes and Richard Phibel).

We welcome anybody that’s interested and willing to do work within the scope of the SIG to join and contribute. See the membership section on the wiki for the current members list and how to join.

Releases and Packages

Unless otherwise specified, packages are available in our main repository, which can be enabled with dnf install centos-hyperscale-release. Please report any issues with these packages on our package-bugs tracker.

Documentation

We have continued fleshing out our user documentation website, and recently completed a major restructuring that will hopefully make content easier to find and consume. Recent additions also include expanded and revamped documentation for SIG contributions around packaging and kernel, a rewrite of our branches policy and a new section on communications, with details around our channels where the SIG can be reached and our live streams.

As previously mentioned, we would very much welcome any feedback and contributions you might have for this documentation.

systemd

The latest version in the Hyperscale SIG is systemd 251.4 for both CentOS Stream 8 and CentOS Stream 9. While the “hs+fb” version has been tagged and rolled out within Meta, we are still working on resolving issues with SELinux policies in the “hs” version before tagging and releasing it. In the meantime, the “hs” version is available on CBS for testing.

If you’re interested in learning more about how we roll out systemd in the Hyperscale SIG, we did a talk about it at the CentOS Dojo this past August. You can find out more about this and our other systemd-related conference activities this quarter in the conference recap linked below.

Kernel

We have published a new build of the el8 kernel, which includes a bugfix for the perf package, which had previously been uninstallable.

Container images

Our container build pipeline is now fully automated, and container images are built on the CentOS Open Shift CI/CD infrastructure and published weekly on Quay.

Spin images

Neal has been working on image build descriptions for the Hyperscale Workstation, Cloud, and Vagrant images for CentOS Stream 9 using KIWI. In order to support that work, we worked with the CentOS infrastructure to get support for using KIWI for building images deployed to CBS and we’re now testing it. This is now live, though currently we cannot build release images through it due to issues with CBS assuming everything going out being RPM content.

Package updates

We’ve published updated backports of wireshark (for CentOS Stream 8) and fio (for both CentOS Stream 8 and 9), based on the existing Fedora packaging. We’ve also updated the ethtool backport for CentOS Stream 9 to 5.16.

As part of the ongoing work to package QEMU in EPEL, we’ve started working on a Hyperscale backport to make it easier to iterate on this work. As a prerequisite, we’ve published updated backports of meson, edk2 and SLOF in the Experimental repository. We’ve also requested to add edk2 and SLOF to CRB and upstreamed a couple of build fixes to the Fedora QEMU packaging.

DNF/RPM stack with CoW support

The Copy-on-Write stack was rebuilt on top of the latest upstream changes. We’ve also identified an incompatibility between CoW and some external packages from Microsoft that slightly deviate from the RPM specifications. As a result, we have improved our tooling robustness, and are engaging with Microsoft to get their packages fixed.

Health and Activity

The SIG continues to maintain a healthy development pace.

Meetings

The SIG holds regular bi-weekly meetings on Wednesdays at 16:00 UTC. Meetings are logged and the minutes for past meetings are available.

The SIG uses the #centos-hyperscale IRC channel for ad-hoc communication and work coordination; this channel is also bridged on Matrix in the #centos-hyperscale:fedoraproject.org
room. For async discussions and announcements we generally use the centos-devel mailing list. The SIG also holds open monthly video conference sessions to promote collaboration and social interaction.

Conference talks

We’ve published a recap of our conference activities from the past few months on the CentOS Blog. As a reminder, we also have a page keeping track of our conference presentations with links to recordings and slides where available.

A number of SIG members are tentatively planning to attend FOSDEM in February 2023.

Live streams

The SIG periodically does work live on Twitch from its official Twitch channel. Interested parties who want to watch and interact with us as we do work should follow us on Twitch to get notified for when we stream.

Planned work

The SIG tracks pending work as issues on our Pagure repository. Notable projects currently in flight include:

  • using CBS to build our spin images
  • shipping an updated QEMU package in EPEL
  • integrate btrfs transactional updates as an optional feature

Issues for the Board

We have no issues to bring to the board’s attention at this time.

CentOS Hyperscale SIG conference recap

September 29, 2022 05:03 PM

In the past couple of months members of the CentOS Hyperscale SIG attended several conferences where they were able to share the work the SIG is doing and meet up in person, in some cases for the first time.

We have a page tracking conference presentations around Hyperscale-related topics. You can find references there to all talks mentioned below, including video recordings where available.

Conferences aren’t just about presentations though. The “hallway track” provides a great opportunity for serendipidous connection, and the various social events are often a great venue for folks to mingle and get to know each other in an informal setting.

If you’d like to meet us in person at a future event please reach out. We also generally cover conferences we plan to attend in our quarterly reports.

SCaLE 19x

Anita Zhang, Davide Cavalca, and Neal Gompa attended SCaLE 19x in Los Angeles at the end of July.

Anita presented two systemd-related talks: The Curious Case of Memory Growth which walks through debugging a regression in the Journal and – together with Alvaro Leiva Geisse – Journey into the heart of systemd, providing a practical introduction to systemd and its abilities.

Davide presented Building the future with CentOS Stream, covering the evolution of CentOS throughout the years and Meta’s learned experience engaging with the community.

Conferences videos for SCaLE have not been published yet, but recordings of the livestream feeds are available on YouTube, and linked from our tracking page as well.

CentOS Dojo and DevConf.US 2022

In August, Anita, Davide, David Duncan, Jack Aboutboul, Neal, and Quentin Deslandes attended DevConf.US 2022 and the co-located CentOS Dojo event.

Joined remotely by Daan De Meyer, Anita talked at Dojo about managing and automating systemd releases within the Hyperscale SIG in Adventures with systemd in Hyperscale. At the same event, Davide presented another Hyperscale SIG update covering the latest developments.

Also at Dojo, Neal talked about Making custom CentOS images with KIWI, which featured a live demo and a repository of example KIWI image build data files. Later in the week, Neal expanded on the subject of image building at his Golden Images for Scaling Up with the Best of Them talk during DevConf.US.

Shaun McChance also posted a report of this event on behalf of the Promo SIG.

Hyperscale face-to-face meetup

The day before Dojo, we also hosted the first face-to-face Hyperscale SIG meetup. Anita, Davide, David, Neal, and Quentin participated in person, joined by Shaun, who had helped organize the event. While this was primarily meant as an in-person event, we had a conference bridge setup to allow remote folks to join, which allowed people to follow the conversation and drop in and out as their scheduled allowed. Among others, Daan and Manu Bretelle participated in the event remotely this way.

We had a lot of great conversation at the meetup, covering specific work items, general brainstorming for future work and potential process improvements. Everybody agreed that the event was really useful and we will definitely try to organize more of these in the future.

The meetup wasn’t recorded, but there are notes of the discussion, and the various work items that were brought up will soon be reflected in tickets on our SIG tracker.

Linux Plumbers Conference 2022

Anita, Davide, Daan, Manu, and Quentin attended Linux Plumbers Conference 2022 in Dublin in September. This was a hybrid event, also allowing Michel Salim and Neal to attend remotely.

Anita organized the Service Management and systemd micro-conference, featuring day-long presentations and discussions around systemd. Daan presented there his latest work on Journal optimization in Slimming down the journal.

The conference also featured several Birds-of-a-Feather sessions to facilitate topic-specific discussion. Among others, SIG members participated in the systemd BoF and the Btrfs BoF.

Conferences videos for LPC have not been published yet, but recordings of the livestream feeds are available on YouTube, and linked from our tracking page as well.

Tru Stepping Down

Tru Huynh has decided to step down from the Board of Directors. We thank him for his many years of hard work on the Board and across the entire CentOS project.

Jefro Stepping Up

The CentOS Board has appointed Jeffrey “Jefro” Osier-Mixon to fill the vacancy. Jefro has been instrumental in developing the Automotive SIG.

Dojo @ DevConf

CentOS hosted a Dojo in Boston at DevConf.US. This free mini-conference featured nine talks on a variety of subjects from the Enterprise Linux ecosystem. We also live streamed and took questions from remote participants, which is something we plan to continue for future in-person events. The recordings are available on YouTube.

SIG Reports

Each month, we publish a rotating selection of quarterly reports from our Special Interest Groups. This month includes reports from the Artwork and Virtualization SIGs.

Artwork SIG

Purpose

The CentOS Artwork SIG exists to produce the CentOS Project visual identity. See https://wiki.centos.org/SpecialInterestGroup/Artwork

Membership Update

There is not membership changes. We are always looking for new members.

Releases

CentOS Brand v2

The CentOS Logo

The CentOS Brand v2 is the new visual identity of the CentOS Project. We encorage you to use it abundantly. It was recently approved, and is where we will be transitioning to.

The source files related to CentOS Brand v2 are publicly available at centos-brand repository, which purpose is to:

  1. Consolidate devlopment of CentOS Brand design, usage, and presentation.
  2. Consolidate automation jobs for rendering the CentOS Brand consistently (e.g., through GitLab pipelines, that you could include on your own projects).

The CentOS Brand is released under the terms of Creative Commons Attribution-ShareAlike 4.0 International Public License, and usage limited by CentOS Trademark Guidelines.

The previous brand, CentOS Brand v1, is still ative and will stand so under the term “CentOS Classic” instead of just “CentOS”.

Healthy and Activity

Health

We are here; doing what we can, when we can.

Recent activities related to website redesign

The design of CentOS websites happens at jekyll-theme-centos repository, a gem-based theme for Jekyll. When a design change enters the theme, it can be reviewed immediatly to make corrections. The theme is available as open source under the terms of the MIT License. This section describes changes we are introducing into jekyll-theme-centos. Keep in mind these changes are not final.

Toolkit

We are moving jekyll-theme-centos development from Bootstrap 4 to Bootstrap 5. The number of custom CSS classes added on top of Bootstrap’s default ones is being reduced to make transition from one version to another easier in the future. As consequence, the HTML is also being rewritten to support Bootstrap-only classes and retire all those which aren’t. Though, there may be few exceptions still.

Typography

Montserrat and Overpass continue being the two typographies used in the website.

CentOS Brand Scalability

Presenting the CentOS Brand consistenly in different visual manifestations is high priority for the Artwork SIG. We are changing the file format from PNG to SVG to address rastered image quality degradation when the CentOS Brand is presented on very high resolution monitors. The SVG support seems to be pretty good in modern browsers.

Legibility on headers and footers

We are retiring the artistic motif background from website header and footers in favor of a plain color instead. The plain color at the moment is the same color used in CentOS Brand, to establish the visual connection with it. Footers and navbars backgrounds use a darker color to provide enough contrast with headers.

Before After

The artistic motif is still relevant to reinforce the visual connection between different visual manifestations. So, it is still present in the home page, using CentOS Distribution screenshots.

CentOS Distribution

We are adding a carousel of screenshots related to CentOS Distributions. This has two purposes. One, connecting the CentOS Brand with the artistic motif used by default in the CentOS Stream distribution. Second, showing the world what CentOS Stream looks like with images, not just text.

News, events and blog posts

We are replacing a home page title, from “Around CentOS” to “Blog posts”. The position of these sections is being aligned horizontally instead of vertically.

CentOS Sponsors

The sponsors presentation occurs one-image-at-a-time, every few seconds. We are exploring a two rolling rows of 6 images each at the end of the home page, where the sponsors logo is randomly loaded from the entire list of active sponsors. In this layout, 12 sponsors will be always visible at once, in a reasonable amount of space, attractively. Hopefully, another set of 12 sponsors will be visible, the next time the home page is reladed, and so on.

The images used in the screenshot are marely for testing purpose, they don’t represent real sponsors in any way. Once the gem-based theme is installed, the sponsor images stored in the theme are ignored and the images stored in assets/img/sponsors/ directory are used instead.

The “becoming a sponsor” link is more visible now.

Before After

We are retireing the sponsor section from the website footers in favor of the sponsor section in the website home page. Sites like mailling lists that need a sponsor image on footer, will continue using it.

Issues for the Board

None.

Virtualization SIG

In the last quarter upstream had a few releases with binaries now mostly shipped via CentOS Virt SIG:

We are now building kata-containers for c9s as well, with the latest release (2.5.0) already available.

How updates work in CentOS

September 06, 2022 01:31 PM

This document is an attempt to explain the relationship between Fedora Linux, CentOS Stream and RHEL, with a specific focus around how package updates flow between them.

From Fedora to CentOS Stream

Fedora is where day-to-day development and innovation happens. Fedora Linux releases every 6 months and each release is maintained for about 13 months. Major changes should be (and almost always are) deployed in Fedora first, following the Change process. Fedora packages sources are maintained in dist-git and built in Fedora Koji.

At the beginning of the development cycle of a new CentOS major release (meaning, 9, 10, etc.), Fedora is branched into the new distribution. Historically, this is done from the current stable Fedora release at the branching time (e.g. Fedora 34 for CentOS Stream 9). After the distribution is branched, the development cycle for the new CentOS Stream release begins.

Nowadays, Fedora ELN helps prepare for the branching process by continuously rebuilding Rawhide (the development version of Fedora). This provides a view into what a new CentOS Stream could look like if it were branched from Fedora today, and ensures that the spec file logic stays compatible with the future set of EL macros and build flags at any given point in time.

From CentOS Stream to RHEL

CentOS Stream package sources are maintained in GitLab, and that is where most of the distribution development work happens after branching. Packages are built on the CentOS Stream Koji and are delivered as part of regularly-produced distribution composes. Composes for Stream are generated 2-3 times a week, and they usually include updates that have been released during that time window, but there is no actual SLA around updates flowing into Stream.

RHEL point releases are essentially, but not actually, a snapshot in time of a given Stream compose, with actual development work happening on the Stream side and showing up there first. In general, a given package will go through QA, then land into Stream, then down the road be incorporated into the next RHEL minor release. In this sense, Stream acts as a continuously-delivered preview of the next RHEL minor release. Aleksandra Fedorova also talks about this process in detail in her OpenInfra Summit talk.

Once a given RHEL release is out, the corresponding sources are delivered on git.centos.org, where they can be consumed by RHEL rebuild projects such as Alma Linux and Rocky Linux.

Deep dive: critical security erratas

As explained above, the general assumption is that packages will land in CentOS Stream first. There is one exception to this, which is embargoes security fixes and security erratas rated critical or important. These are developed by Red Hat and held until the embargo expires. They are then released to RHEL first, and then flow into Stream.

There’s two practical scenarios at hand here.

RHEL and CentOS Stream have a package with the same NVR

When an errata comes out for RHEL, the package is updated there. In this case, you will see the same NVR that came out for RHEL come out for Stream as well.

The polkit CVE from last December is a good example of this: both RHEL 8 and CentOS Stream 8 were at polkit-0.115-11.el8_4.1 before the CVE, and polkit-0.115-13.el8_5.1 fixes the CVE in both.

CentOS Stream has a package with a greater NVR than RHEL

In this scenario, CentOS Stream is ahead of RHEL for a given package. When an errata comes out for RHEL the package is updated there, but its version remains behind the Stream one. In this case, assuming the update still applies to the CentOS Stream version, a new update will be made for Stream, either by backporting the changes onto the latest Stream package version or by rebasing the package.

Another CVE, this time in libxml2, provides a good example of this. RHEL was at libxml2-2.9.7-9.el8 before the CVE, and issued a fixed package as libxml2-2.9.7-9.el8_4.2. Within Stream, the fix was instead included in libxml2-2.9.7-11.el8.

Deep dive: CentOS Stream 8

CentOS Stream 8 was the first version of CentOS where the Stream development process was introduced, and has some significant differences. Notably:

  • CentOS Stream 8 package sources are hosted on git.centos.org (under the c8s branch) instead of GitLab
  • because of technical limitations, the contribution process for CentOS Stream 8 is different; the standard PR workflow isn’t supported, and the best way to contribute patches is by attaching them to a Bugzilla ticket against the relevant component
  • CentOS Stream 8 packages are build on the Koji mbox instance

There is ongoing work to migrate CentOS Stream 8 onto the current development process and tooling, and the hope is to eventually minimize and hopefully eliminate these differences.

Purpose

Packaging and maintaining different FOSS based Private cloud infrastructure applications that one can install and run natively on CentOS.

https://wiki.centos.org/SpecialInterestGroup/Cloud

Membership update

The OKD (OpenShift community edition) team contacted the Cloud SIG in order to know whether they could join our effort. Their contributors are looking for the best way to provide OKD along with SCOS (CentOS Stream CoreOS) images. As OKD and SCOS onboard into the community, it was suggested one of the contributors fill the vacant CloudSIG co-chair position.

Releases in the most recent quarter

RDO

Yoga is still the latest release. RDO community is about to package the next release named “Zed” in a couple of weeks, which will be supported on CentOS Stream 9 only. As a reminder Yoga is used as a transitive Openstack release with CentOS Stream 8 and 9 support, in order to be able to migrate the OS from one to another.

Health and activity

The Cloud SIG remains fairly healthy. However, it is still, for the most part, a monoculture containing only OpenStack.

Storage SIG

Package updates since the last report:

  • Glusterfs 10 updated to glusterfs-10.2, packages are available for Stream 9 and Stream 8.
  • Glusterfs 9, no update to glusterfs-9.
  • Ceph Quincy (17) updated to ceph-17.2.2, packages are available for Stream 9, Stream 8, and RHEL8.
  • Ceph Pacific (16) updated to ceph-16.2.10, packages are available for Stream 9, Stream 8, and RHEL8.
  • Ceph Octopus (15), no update to ceph-15.
  • NFS-ganesha 4 and libntirpc 4, no updates.
  • Apache Arrow updated to libarrow-8.0.1, packages are available for Stream 9, Stream 8.
  • Apache ORC updated to liborc-1.7.5, packages are available for Stream 9, Stream 8.

Note: Dependencies for Ceph Quincy (17) and earlier that are not in CoreOS, CBR/PowerTools, or AppStream are provided by the Storage SIG. Starting with Ceph Reef (18) those dependencies will be provided by EPEL instead. This includes Apache Arrow (libarrow), Apache ORC (liborc), and a rather lengthy list of other packages. This will simplify building dependencies by only requiring that they be built in one place. Many developers and end users also tend to prefer EPEL, and enable EPEL by default, and this will reduce or outright eliminate conflicts between packages in EPEL and packages in the Storage SIG. And no, Ceph itself will not be in EPEL; it will remain solely in the Storage SIG.

Following are the updates for Samba:

  • Samba 4.16, updated to latest version 4.16.3 on Stream 9 and Stream 8.
  • Samba 4.15, updated till the latest version 4.15.8 on Stream 9 and Stream 8. RHEL8 builds are also available.
  • Samba 4.14, in CVE fixes only mode.

Issues reported:

  • In the light of user report for a crash during Samba daemon start up efforts are underway to ensure that system installed versions of dependent libraries like libtalloc, litdb, libtevent and libldb does not interfere with corresponding copies internally within builds.

CentOS Automotive SIG: First Year in Review

August 26, 2022 05:00 AM

In August 2021, the CentOS Automotive SIG launched and held its first meeting with 36 participants. We had no infrastructure, no solid architectural plans, and no documentation - just a very motivated group that very quickly grew beyond Red Hat and into the automotive community.

Things have certainly changed since then! Technical lead Pierre-Yves Chibon has provided a list of the many accomplishments over the past year:

  • We worked to define what the Automotive SIG is producing and we landed on three artifacts:
    • AutoSD, a CentOS-Stream based linux distribution which is the public, in-development version of the Red Hat In-Vehicle Operating System (similar to CentOS Stream for RHEL).
    • An Automotive SIG RPM repository that allows the community to expand the content of AutoSD or experiment with some of its parts.
    • Sample images, built using OSBuild, which provide examples of how to assemble production images based on AutoSD, customized for some hardware, including container images, based on CoreOS/ostree technologies.
  • We created a repository on gitlab, with the infrastructure to enable CI/CD for a basic distribution.
  • We worked with the CentOS Infrastructure team to enable the use of gitlab namespaces for SIGs under the main “CentOS” namespace on gitlab.com. Documentation available
  • We worked with the CentOS Infrastructure team to enable flat dist-git layout, allowing easy backporting of work done in Fedora but also a consistent developer experience for people working on Fedora, CentOS-stream and in the Automotive SIG. 
  • Similarly, we've worked with the CentOS Infrastructure team to allow the lookaside cache used by SIGs to support the same structure as the lookaside cache used in Fedora and in CentOS Stream. All of this work is now available to all CentOS SIGs (as opt-in) and is fully documented.
  • We picked the Raspberry Pi 4 as our first demo hardware to support as it is (well, as it was…). We have included support for this hardware in the kernel-automotive package available both in the Automotive SIG RPM repository as well as in AutoSD itself.
  • We are building a set of nightly images for different use-cases.
  • For every merge-request opened against the repository hosting the definition of our sample images, we have CI running,validating that the changes we make do not break the building of our images
  • Finally, we worked on documenting a large number of use cases, such as:

While we are proud of this work so far, it is just the beginning as we develop our relationships with other communities, including SOAFEE and Eclipse SDV, and further refine AutoSD. We hope to see you at a future meeting, or on our mailing list and Matrix chat.

Summer Dojo Videos

We held an online Dojo on June 17. Videos of the talks are now available.

DevConf Dojo

CentOS is hosting an in-person Dojo at DevConf.US. Dojos are free mini-conferences with sessions on a range of topics in the Enterprise Linux ecosystem. This Dojo takes place on August 17 at Boston University. Registration is free but strongly recommended. We also have a room block at the nearby Residence Inn. See the event page for details.

The call for presentations is open thru July 22. We’d love to hear what you’re doing with CentOS.

Hyperscale SIG Meetup

The CentOS Hyperscale SIG will be holding an in-person meetup on August 16th, 2022 at Boston University. This is the same venue hosting CentOS Dojo on August 17th and DevConf.us on August 18th-20th. The meetup is open to everybody interested – you don’t have to be a member of the SIG to attend, and we’d welcome participation from anyone interested in this space.

The event will be held from 9am to 5pm in the GSU conference room 310 at Boston University. While this is an in-person event, we will do our best to setup a conference bridge so that remote participants can attend and interact as well.

Please register at https://www.eventbrite.com/e/centos-hyperscale-sig-meetup-dojodevconfus-2022-tickets-384259589777 to help with the event planning.

CentOS CI

CentOS CI is going hardwareless. The CentOS CI team will be retiring hardware as it reaches end of life. They will take this opportunity to modernize infrastructure and move to a hybrid cloud environment.

Read the announcment and watch the video of the Dojo session on CentOS CI.

Alternate Images SIG Proposal

Troy Dawson has proposed an Alternate Images Special Interest Group. This SIG would produce ISO images that aren’t produced by the core CentOS Stream, including live images and alternate install images. Discussion is ongoing.

SIG Reports

Each month, we publish a rotating selection of quarterly reports from our Special Interest Groups. This month includes reports from the Software Collections, Hyperscale, Kmods, and Automotive SIGs.

Software Collections SIG

Purpose

Provide an upstream development area for various software collections and related tools.
Provide RedHat authored and released collection packages for CentOS.

Membership

No membership changes.
New members are always welcome, and they would help to alleviate the issues outlined below.

Releases and packages

No major releases in the last quarter.
The RedHat packages are being rebuilt and released semi-regularly.

Health and activity

The group is mostly passive, focusing on the rebuild and maintenance of existing packages.
It has a single active member (jstanek), and this shows in various places:

  • The https://softwarecollections.org website is being kept online, but the content is out of date; technical issues with current hosting prevents log-in and updating the content.
  • Changes in the CentOS infrastructure resulted in broken CI; rebuilt packages are no longer being tested automatically. Fixing this is planned, but no ETA.

In short, the amount of work needed grows faster than jstanek is able to keep up.
Additional members would be very welcome.

Hyperscale SIG

The Hyperscale SIG has posted their quarterly report on the CentOS blog.

Kmods SIG

This report covers work that happened since last report. The previous report can be found here.

Purpose

Packaging and maintaining kernel modules for CentOS Stream and Enterprise Linux.

Membership Update

No SIG members have been added since last report. We welcome anybody that’s interested and willing to do work within the scope of the SIG to join and contribute.

Support for CentOS Stream 9 / EL9

The Kmods SIG provides packages for CentOS Stream 9 and will for EL9 once available in CBS.

Support for CentOS Stream 8 / EL8

The Kmods SIG continues to provide packages for CentOS Stream 8 and EL8.

New Packages

See Kmods SIG’s documentation for lists of available packages. This documentation also provides further information, e.g. how to enable the Kmods SIG’s repositories.

Note that the kernel modules provided by the Kmods SIG are currently not signed with a private key. Hence it is required to disable Secure Boot to be able to use any of these kernel modules.

Please report any issues with these packages in the corresponding project on gitlab.com/CentOS/kmods or here in case the issue is not related to a particular package.

Recent Activities

The Kmods SIG is currently moving all of its resources to gitlab.com/CentOS/kmods. Moving to gitlab.com allows us to use the GitLab CI for the automated detection of required kernel module rebuilds due to kABI changes, i.e., it is now all public and everybody can see what’s going on. We also changed the structure of some of the kernel module repositories. Where appropriate we have dedicated source-git and dist-git repositories where the dist-git is auto-generated from the source-git and manual changes are only meant to be applied to the source-git repository. These changes were implemented to make it as easy as possible for everyone to contribute improvements or bug fixes.

Health and Activity

The Kmods SIG maintains a healthy development pace.

Communication

Regular meetings are scheduled monthly, in the first week, on Monday at 1600 UTC in #centos-meeting. Everyone is welcome to join!
You can also get in touch with SIG members at any time in #centos-kmods.

Open Issues

  • Signing kernel modules: This requires collaboration and further discussion with Infra SIG. Especially about how to securely store a SIG specific key that can be used in CBS, but is not accessible by any unauthorized person.
  • Driver Disks: The SIG would like to provide Driver Disks required to install CentOS Stream on unsupported hardware. The current state can be tracked here.

Issues for the Board

The Kmods SIG asks for clarification concerning the possibility of SIGs creating content for RHEL 8 and 9. Open questions include support for release packages, see extras-common tag, and for how long SIGs can expect to be able to build for RHEL, e.g., up till end of “Full Support” or “Maintenance Support” of the RHEL life cycle.

Automotive SIG

Membership update

This SIG does not have a formal membership process. The mailing list currently has 94 subscribers representing at least 30 organizations, though not all subscribers use corporate emails and some are participating as individuals.

Releases in the most recent quarter (or most recent release, if none in that quarter)

The SIG provides a new distribution: Automotive Stream Distribution (AutoSD), a CentOS Stream derivative designed specifically around the needs of an automotive OS, and transparently the upstream project for Red Hat’s eventual in-vehicle OS product. AutoSD has been downloaded and used by several organizations who have commented or asked for help, so we know it is getting some traction though of course we don’t have exact metrics on usage.

Health report and general activity narrative.

The SIG has had two public meetings per month, one formal and one informal “office hours”, each with 25-40 attendees, with visible participation from 7-10 separate organizations. This SIG is intended to be a community effort with contributions and shared benefits from all participants. All formal meetings are recorded and posted on this page:
https://wiki.centos.org/SpecialInterestGroup/Automotive/Meetings

Several Red Hat employees made the initial contributions to the project as well as the infrastructure required to build and test it. We now occupy a gitlab repository building software regularly using CI, with build instructions provided on the documentation page at https://sigs.centos.org/automotive/. Sample images are present and downloadable along with customization and build instructions.

This is a high-level summary of current activity:

CentOS Hyperscale SIG Quarterly Report for 2022Q2

July 07, 2022 03:29 PM

This report covers work that happened between April 5th and July 4th. For previous work, see the 2022Q1 report.

Purpose

The Hyperscale SIG focuses on enabling CentOS Stream deployment on large-scale infrastructures and facilitating collaboration on packages and tooling.

Membership update

Since the last update, the SIG members have remained the same.

Justin Vreeland has decided to step down as co-chair of the SIG, and Neal Gompa has been elected to fill the vacancy. We thank Justin for all of his work in establishing the SIG and getting it up to speed and welcome Neal in his new role as co-chair. Neal will be serving alongside Davide Cavalca, who remains in the other co-chair seat.

We welcome anybody that’s interested and willing to do work within the scope of the SIG to join and contribute. See the membership section on the wiki for the current members list and how to join.

Releases and Packages

Unless otherwise specified, packages are available in our main repository, which can be enabled with dnf install centos-hyperscale-release. Please report any issues with these packages on our package-bugs tracker.

Documentation

We have continued fleshing out our user documentation website. Recent additions include details about our containers image build process and our ELN Extras workflow. We’ve also expanded our documentation around the systemd release process to cover the use of the CI/CD infrastructure. Finally, we have started formally documenting the SIG governance processes.

As previously mentioned, we would very much welcome any feedback and contributions you might have for this documentation.

systemd

The latest released version in the Hyperscale SIG is systemd 250.3, for both CentOS Stream 8 and CentOS Stream 9. We are in the process of deploying systemd 251.2.

We also updated the systemd daily CI to work with the new release process that was introduced along with the update to 250.3. The script was rewritten in Python and updated to run CI against both Centos Stream 8 and Centos Stream 9. On top of that, we added documentation on how to update the corresponding containers running in Openshift with any new changes made to the scripts.

Finally, we updated the release documentation in preparation for the release of 251.2.

Kernel

The brtfs-progs package was updated to 5.16.2 on both CentOS Stream 8 and CentOS Stream 9. Additionally, we have started distributing the compsize utility (based on its Fedora packaging) in the SIG experimental repository.

We have also updated the kpatch package to include some additional bugfixes backported from upstream.

Container images

We have started working on automating the container build pipeline by leveraging the Open Shift CI/CD infrastructure. The in-progress work is currently up for review.

Package updates

We have published updated backports of the TPM stack for CentOS Stream 8, notably tpm2-tss and tpm2-tools, based on the existing Fedora packaging. Also for CentOS Stream 8, we have published a patched version of cloud-init with support for newer EC2 metadata versions. We have also contributed upstream fixes for this for CentOS Stream 8 and CentOS Stream 9.

On the development front, we have spun up a CI pipeline to detect package updates in upstream CentOS that would supersede our versions and alert us, so that we can publish updates in a timely basis. This pipeline leverages the MQTT broker where git.centos.org event notifications are published. While this was written for Hyperscale, we hope it could be useful for other SIGs as well.

DNF/RPM stack with CoW support

The Copy-on-Write stack was rebuilt on top of the latest upstream changes.

Health and Activity

The SIG continues to maintain a healthy development pace.

Meetings

The SIG holds regular bi-weekly meetings on Wednesdays at 16:00 UTC. Meetings are logged and the minutes for past meetings are available.

The SIG uses the #centos-hyperscale IRC channel for ad-hoc communication and work coordination; this channel is also bridged on Matrix in the #centos-hyperscale:fedoraproject.org
room. For async discussions and announcements we generally use the centos-devel mailing list. The SIG also holds open monthly video conference sessions to promote collaboration and social interaction.

Conference talks

Last quarter, Davide Cavalca presented an update on SIG activities at CentOS Dojo, Summer 2022 (slides, video).

A number of SIG members plan to attend CentOS Dojo, DevConf.US 2022 and DevConf.US 2022 in Boston next month. Davide Cavalca has submitted another update on SIG activities there, and Neal Gompa has submitted a talk to introduce image building. We also plan to hold a Hyperscale meetup alongside these events, likely on August 16th. Details will be shared as soon as the venue is finalized.

A SIG-adjacent talk around CentOS Stream will be presented at SCALE 19x later this month.

Live streams

The SIG periodically does work live on Twitch from its official Twitch channel. Interested parties who want to watch and interact with us as we do work should follow us on Twitch to get notified for when we stream.

Planned work

The SIG tracks pending work as issues on our Pagure repository. Notable projects currently in flight include:

  • using CBS to build our spin images
  • shipping an updated QEMU package in EPEL
  • integrate btrfs transactional updates as an optional feature
  • publish spin images for CentOS Stream 9

Issues for the Board

We have no issues to bring to the board’s attention at this time.

We are here; doing what we can, when we can.

Recent activities related to CentOS Symbol redesign

The contrast issues related to CentOS Symbol redesign has been addressed with the following composition:

This design uses only two colors, the CentOS Purple (#a14F8C) and the CentOS White (#ffffff). The outer square is being considered an integral part of the symbol itself and must not be removed from it, to provide acceptable recognition on top of both dark and light backgrounds. From all the four CentOS colors available, the purple one seems to provide the best background neutrality.

Soureces related to this design are available at https://gitlab.com/areguera/centos-brand/-/tree/v2-centos-artwork-sig-issue-5 and you are welcome to contribute.

Tests related to size:

16x16 22x22 24x24 32x32 36x36 48x48 96x96

Recent actitivities related to CentOS word transition from Denmark to Montserrat typography

Issue 71: The images necessary to implement the transition from Denmark to Montserrat typography are already in the centos-logos repository, the upstream location used to build the centos-logo package. Please, see the content provided in release 90.7. Presently, the centos-package is built based on source release 90.4.

The Artwork SIG cannot make changes in the centos-logo spec. We only can update the upstream repository with the images you need, and tag the changes with a new version, so for a Red Hat developer to do the source version swift.

Recent actitivities related to website visual corrections

It has been reported an issues related lists.centos.org visual presentation. See https://github.com/CentOS/ansible-role-mailman/issues/15.

A redesign simplification is being considered to “flatten” the web site presentation using CentOS colors only.

Issues for the Board

None.

Virtualization SIG

For oVirt:

  • Membership update: new members from oVirt project joined the SIG: Sharon Gratch, Eitan Raviv, Harel Braha, Lev Veyde, Yedidyah Bar David, Ori Liel (please add yourself if I missed you as joined in the last quarter)
  • Releases and Packages: oVirt 4.5.0 has been released upstream using CentOS Virtualization SIG for shipping binaries except for a few packages which couldn’t build within the CentOS Community Build Service.
  • Health and Activity: oVirt is pretty active.
  • Issues for the Board: CentOS Stream is lacking important and critical security updates compared to already released RHEL content. An effort on making CentOS Stream more secure would be welcome (example: as of June 1st the latest kernel in CentOS Stream 8 is kernel-4.18.0-383.el8 which was built on 2022-04-20, it’s laking CVE fixes delivered over the last 40 days in RHEL 8.6)

SIG Reports

CentOS Special Interest Groups focus on work around CentOS Stream. Each SIG reports quarterly in this newsletter.

Storage SIG

Package updates since the last report:

  • Glusterfs updated to glusterfs-9.5 and glusterfs-10.1; packages are available for Stream 9 and Stream 8.
  • Ceph Quincy (17) was released; packages are available for Stream 9, Stream 8, and RHEL8.
  • Ceph Pacific (16) updated to ceph-16.2.7, with 16.2.8 expected any day now; packages are available for Stream 9, Stream 8, and RHEL8.
  • Ceph Octopus (15) was updated to 15.2.16; packages are available for Stream 8 and RHEL8.
  • NFS-ganesha-4 and libntirpc-4 were released; packages are available for Stream 9, Stream 8, RHEL8, and CentOS 7. NFS-Ganesha-3 is now EOL upstream.

New packages in the Storage SIG:

  • Apache Arrow (libarrow-7.0.0) and Apache ORC (liborc-1.7.4) and their dependencies are now in the Storage SIG. Ostensibly they are provided as dependencies for Ceph Quincy. Packages are available for Stream 9, Stream 8, and RHEL8.

Cloud SIG

Purpose

Packaging and maintaining different FOSS based Private cloud infrastructure applications that one can install and run natively on CentOS.

Releases in the most recent quarter (or most recent release, if none in that quarter)

RDO

April 27 2022 - Yoga release https://blogs.rdoproject.org/2022/04/rdo-yoga-released/

In the last few months, the SIG worked hard on bootstrapping Yoga OpenStack release onto CentOS Stream 9. The initial plan was to release Xena onto CS9 but because of bad timing due to uncertainty about CS GA plans, we coudln’t make it. The positive point is that we had more time to add CS9 as the supported Operating System to the OpenStack project.

Adding CS9 to OpenStack CI provided valuable feedback as it allowed us to catch issues early in the CI, it was challenging but proved valuable. Note that RDO will use Yoga as a transitive Openstack release with Cloud Stream 8 and Cloud Stream 9 support, in order to be able to migrate the OS from one to another. The next OpenStack release, Zed, will be supported only on CentOS Stream 9.

Continuous Integration

Cloud SIG had migrated all their jobs from older jenkins instance (ci.centos.org) to a new private instance running in the CentOS CI OpenShift environment (https://jenkins-cloudsig-ci.apps.ocp.ci.centos.org/)

Last but not least, RDO related CI pipelines which required only x86_64 nodes have been migrated to RDO Zuul CI/CD
environment in order to reduce node requests.

Health and activity

The Cloud SIG remains fairly healthy. However, it is still, for the most part, a monoculture containing only OpenStack.

Transition to issues.redhat.com

As CentOS Stream 9 stabilizes and we approach a release of RHEL 9, Red Hat is planning to transition to using issues.redhat.com exclusively for reporting issues and requesting features for RHEL and CentOS, deprecating the use of bugzilla.redhat.com. This will be a gradual process as we all figure out the workflows that work best for the CentOS community.

KDE in EPEL 9

Good news for KDE fans. KDE is ready for testing in EPEL 9 for CentOS Stream 9 and related operating systems. EPEL is a project under the Fedora umbrella that builds packages for Enterprise Linux that aren’t available as supported packages in RHEL. CentOS Stream allows EPEL to get ahead of the game and build packages earlier than ever before.

Bringing RHEL docs to CentOS

The RHEL documentation team has been working on moving their content and processes to CentOS. They have made a preview build of their work so far. This is an ongoing effort, and it will take time to upstream everything to CentOS.

Kmods SIG

This report covers work that happened since last report. The previous report can be found here.

Purpose

Packaging and maintaining kernel modules for CentOS Stream and Enterprise Linux.

Membership Update

Unfortunately, Jonathan Billings left the Kmods SIG due to lack of time. We thank him for all the work he contributed to the Kmods SIG: Thank you!

No SIG members have been added since last report. We welcome anybody that’s interested and willing to do work within the scope of the SIG to join and contribute.

Support for CentOS Stream 9 / EL9

The Kmods SIG provides packages for CentOS Stream 9 and will for EL9 once released and available in CBS.

Support for CentOS Stream 8 / EL8

The Kmods SIG continues to provide packages for CentOS Stream 8 and EL8.

New Packages

See Kmods SIG’s documentation for lists of available packages. This documentation also provides further information, e.g. how to enable the Kmods SIG’s repositories.

Notable packages released since last report:

  • btrfs-progs (9 only)
  • kmod-btrfs (9 only)
  • virtual-guest-additions (9 only)
  • kmod-vbox-guest-additions (9 only)
  • ecryptfs-utils
  • kmod-ecryptfs

Note that the kernel modules provided by the Kmods SIG are currently not signed with a private key. Hence it is required to disable Secure Boot to be able to use any of these kernel modules.

Please report any issues with these packages in the corresponding project on pagure.io or here in case the issue is not related to a particular package.

Recent Activities

The Kmods SIG started working on a dnf plugin to improve handling of kABI tracking kernel module packages. See the dnf-plugin-kmods project on pagure.io for further details.

Health and Activity

The Kmods SIG maintains a healthy development pace.

CentOS Hyperscale SIG Quarterly Report for 2022Q1

April 04, 2022 02:52 PM

This report covers work that happened between January 1st and April 4th. For previous work, see the 2021Q4 report.

Purpose

The Hyperscale SIG focuses on enabling CentOS Stream deployment on large-scale infrastructures and facilitating collaboration on packages and tooling.

Membership update

Since the last update, the SIG gained six new members (Manu Bretelle, Daan De Meyer, Oscar Dominguez, Kevin Wells, Ali Koroglu and Brandon Johnson).

We welcome anybody that’s interested and willing to do work within the scope of the SIG to join and contribute. See the membership section on the wiki for the current members list and how to join.

Releases and Packages

Unless otherwise specified, packages are available in our main repository, which can be enabled with dnf install centos-hyperscale-release. Please report any issues with these packages on our package-bugs tracker.

Documentation

We have continued fleshing out our user documentation website. Among other things, we have added extensive documentation of the kernel build and contribution process, greatly expanded the existing systemd documentation and improved our SIG onboarding process.

As previously mentioned, we would very much welcome any feedback and contributions you might have for this documentation.

systemd

The latest released version in the Hyperscale SIG is systemd 250.3, for both CentOS Stream 8 and CentOS Stream 9.

The systemd RPM sources for the Hyperscale SIG have been migrated to use a flat dist-git layout, making it easier to rebase our changes directly on top of Fedora Rawhide. Our specfile will also now build directly with tarballs from the Hyperscale SIG’s systemd Git fork. This change means our backports no longer have to be managed though patch files; they will be included directly from our Git fork.

Kernel

CentOS Stream 9

Updated kernel builds tracking the upstream CentOS Stream 9 kernel have continued to flow into the Hyperscale experimental repository. Of note, we are testing a backport of SimpleDRM with fbdev emulation to ensure Wayland environments work regardless of graphics hardware.

Neal Gompa has written basic automation for updating the kernel. As part of that, the kernel RPM sources for the Hyperscale SIG have been migrated to use a flat dist-git layout. We eventually aim to introduce CI/CD to continually track and test our changes on top of Red Hat’s changes in the baseline CentOS Stream 9 kernel.

CentOS Stream 8

The CentOS 8 kernel is now building with the same sources as our CentOS 9 kernel and work has begun to automate rebases and builds using scripts written for our CentOS 9 kernel.

Container images

We have reworked our container build scripts to properly support CentOS Stream 9, and have pushed updated containers to our registry namespace on Quay.io.

Package updates

CentOS Stream 9

We have contributed updates to SDL2 (to backport fixes for running SDL2 applications as native Wayland applications) and upgraded Flatpak to the 1.12 version series to improve compatibility with the wider ecosystem of Flatpaks.

We also contributed changes to centos-stream-release to make it easier for spins to selectively replace branding packages to producing spins or remixes.

CentOS Stream 8

We have published updates for ethtool (to 5.16) and zstd (to 1.5.1) for CentOS Stream 8.

Spin updates

All necessary image build tools are now shipped in EPEL 9 to support building live media for CentOS Stream 9. This includes the following packages: kiwi, livecd-tools, appliance-tools.

We have started working on the Hyperscale spin based on CentOS Stream 9. In the coming weeks, the Cloud variant of the Hyperscale spin will become available on the Amazon Web Services Marketplace. Other cloud platforms and spin variants will follow shortly thereafter.

DNF/RPM stack with CoW support

The Copy-on-Write stack got rebased on top of RPM’s head as of late January and the change has been ported and distributed under the CentOS Stream 8 and CentOS Stream 9 Hyperscale’s experimental repos.

RPM CoW now verify RPM signatures at transcode time and can re-use this within rpmkeys logic. Likewise, rpm -i does not require the use of --nodigest anymore.

A test suite has been added, testing different scenarios and ensuring that future changes do not break functionalities.

Finally, by removing the need for executable stack, the reflink plugin is now compatible with SELinux-enabled environments.

Sticky Vendor

Hyperscale packages built after February 8, 2022 have their vendor field set to “CentOS Hyperscale SIG”, e.g. systemd-249.4-2.13.hs.el8. This allows users to stick to Hyperscale packages without worrying about a higher NEVRA in other repositories, by setting allow_vendor_change=False.

Health and Activity

The SIG continues to maintain a healthy development pace.

Meetings

The SIG holds regular bi-weekly meetings on Wednesdays at 16:00 UTC. Meetings are logged and the minutes for past meetings are available.

The SIG uses the #centos-hyperscale IRC channel for ad-hoc communication and work coordination; this channel is also bridged on Matrix in the #centos-hyperscale:fedoraproject.org
room. For async discussions and announcements we generally use the centos-devel mailing list. The SIG also holds open monthly video conference sessions to promote collaboration and social interaction.

Conference talks

Last quarter, Davide Cavalca presented an update on SIG activities at CentOS Dojo, FOSDEM 2022 (slides, video). At the same event, Neal Gompa talked about the experience of contributing to CentOS Stream (slides, video).

A SIG-adjacent talk around CentOS Stream has also been accepted for SCALE 19x.

Live streams

The SIG periodically does work live on Twitch from its official Twitch channel. Interested parties who want to watch and interact with us as we do work should follow us on Twitch to get notified for when we stream.

Planned work

The SIG tracks pending work as issues on our Pagure repository. Notable projects currently in flight include:

  • using CBS to build our spin images
  • shipping an updated QEMU package in EPEL
  • integrate btrfs transactional updates as an optional feature
  • setup a continuous build pipeline for the container image on the CentOS CI infrastructure

Issues for the Board

We have no issues to bring to the board’s attention at this time.

CPE Quarterly Update Q4 2021

March 03, 2022 01:40 PM

This is a summary of the work done on initiatives by the CPE Team. Each quarter CPE Team together with CentOS and Fedora community representatives choose initiatives that will be being worked on in this quarter. The CPE Team is then split into multiple smaller sub-teams that will work on chosen initiatives + day to day work that needs to be done.

 

Following is the list of sub-teams in this quarter:

  • Infra & Releng
  • CentOS Stream
  • OSCI – Distrobaker monitoring
  • EPEL
  • CentOS Duffy CI

 

Infra & Releng

About

Purpose of this sub-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.). This sub-team is also investigating possible initiatives. This is done by ARC (The Advance Reconnaissance Crew), which is formed from the Infra & Releng sub-team members based on the initiative that is being investigated.

What the sub-team did in Q4 2021

Fedora Infrastructure

  • Fedora Infra moved their documentation to docs.fedoraproject.org.
  • Migrated discourse2fedmsg from fedmsg to fedora messaging and deployed the app in production. 
  • Migrated most koji builders to Fedora 35 (finished in Q1 2022)
  • Got CentOS stream 9 using mirrormanager (mirrors.centos.org)
  • Helped release Fedora 35 Beta and then Final
  • Kinoite website published.
  • Fedoraproject dnssec keys moved to sha384 from sha1
  • All wiki talk pages have been disabled. We don’t use them or read them.
  • S390x builders moved to the new z15 mainframe. Additional resources allowed us to increase kvm builders from 10 to 20.

CentOS Infrastructure

  • Upgraded openshift for CI tenants
  • Migrated the cico-workspace to CentOS 8-stream instead of CentOS 7
  • Onboarding new SIGs and adapted workflow
  • Migrated sig guide to https://sigs.centos.org/guide and hosting sigs.centos.org SIGs docs (opt-in)
  • Prepared the CentOS Linux 8 EOL/decommissioning steps
  • Migrated several services in infrastructure due to some sponsors leaving the project (willing to sponsor other rebuilds now instead)
  • Rolled out (with Artwork SIG) new visual theme across all centos infra for stream 9 visual style (website, mirrors, mailing-list, etc)
  • Implemented the new mirror.stream.centos.org mirror pool for Stream 9 (that is also used with mirrormanager)

Fedora Release Engineering

ARC

The ARC Team was looking at Bodhi and Image Builder in Q4.

  • Bodhi: 
    • Investigated doing an initiative on Bodhi
    • Looked at splitting Bodhi up into separate packages
    • Investigated decoupling Bodhi from PDC
    • Looked at dependency management
    • Concluded PDC functionality should move to dist-git instead
    • Not suitable for an initiative 
    • Package separation & dependency management work to go ahead outside of initiative work
  • Image Factory
    • Possible replacement for OZ and Image factory
    • Could be used as a service from Red Hat internal team
    • Would likely need to use our own builders for Fedora
    • Fedora IOT moving to image builder could use builders provided by Image builder as it does not support ppc or s390x
    • Initiative going ahead in Q1 2022 to use image builder for Fedora IOT
    • Potentially used for Fedora/CentOS Stream in the future

CentOS Stream

About

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.

What the sub-team did in Q4 2021

  • 1/3 of all srpms built in Stream were modules in Nov (fun/interesting fact!)
  • Automated compose checks for c9s and added repoclosure check for baseOS and app stream
  • We now report on differences between RHEL 9 and CentOS Stream 9 composes
  • Added c9s links on mirror network for downloading!
  • CI testing for SIGs enabled for c9s
  • Started work on bringing c8s and c9s closer
  • Updated the ELN Extras docs
  • Got ELN side tag builds working
  • Started work on Content Resolver buildroot integration

 

OSCI – Distrobaker monitoring

About

In Q4 some of the CPE team were able to assist the OSCI team with some open issues they had that they were finding hard to get to before the end of the year. Our team worked on a way to improve the Distrobaker monitoring to monitor side-tags and have the code update prometheus for metrics on the side-tags. Distrobaker itself is a service which rebuilds the CentOS 9 Stream Koji builds for RHEL 9 in Brew and having good metrics on the application provides useful insights as to how the service is operating.

EPEL

About

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.

CentOS Duffy CI

About

Duffy is a system within CentOS CI Infra which allows tenants to provision and access bare metal resources of multiple architectures for the purposes of CI testing.

We need to add the ability to checkout VMs in CentOS CI in Duffy. We have OpenNebula hypervisor available, and have started developing playbooks which can be used to create VMs using the OpenNebula API, but due to the current state of how Duffy is deployed, we are blocked with new dev work to add the VM checkout functionality.

What the sub-team did in Q4 2021

Reimplement Duffy from the ground up (which is ongoing). It features a new, much cleaner API than the currently deployed version which allows users to allocate differently featured nodes for their CI workflows. It comes with a metaclient app which translates between users of the legacy API and the new one. The Duffy core is agnostic of the features of managed nodes (e.g. bare metal vs. VM, architecture, OS type & version) and shifts that knowledge into configurable node pools with corresponding Ansible playbooks used for provisioning and deprovisioning.

Datanommer/Datagrepper V.2

About

The datanommer and datagrepper stacks are currently relying on fedmsg which we want to deprecate. These two applications need to be ported off fedmsg to fedora-messaging. As these applications are 'old-timers' in the fedora infrastructure, we would also like to look at optimizing the database or potentially redesigning it to better suit the current infrastructure needs.

For phase two, we would like to focus on a DB overhaul.

What the sub-team did in Q4 2021

The team migrated the datanommer and datagrepper tools to use TimescaleDB as a backend, instead of plain PostgreSQL. This will greatly improve the scalability of the apps. As a reminder, datanommer stores all messages ever sent to our message bus (and that’s a lot of messages), and datagreppers is a web UI and API to query this database.

CentOS Automotive SIG Announces New AutoSD Distro

March 01, 2022 11:59 PM

Introducing the Automotive Stream Distribution

The CentOS Automotive SIG is excited to announce the Automotive Stream Distribution. This is a binary distribution developed within the SIG that serves as a public, in-development preview of the upcoming Red Hat in-vehicle OS.

In August 2021, the CentOS project announced the launch of the CentOS Automotive SIG. The purpose of this SIG is two-fold. First, it is meant to be a neutral public space for collaboration between third parties interested in open development of software targeted at in-vehicle automotive use cases. Second, it is meant to provide such projects with build and test infrastructure.

The goal of the SIG is to provide an open-source home for RHEL-oriented automotive work, and to attract and encourage open development of automotive software between commercial and non-commercial partners.

As this RHEL-oriented automotive work is being defined, it has become clear that having multiple development stages would be most beneficial. We have identified three of these stages:

  • The CentOS Automotive SIG open to anyone and everyone to build, test, experiment, and contribute with software for the automotive industry.
  • The Red Hat automotive product,—the product itself that Red Hat sells and supports. The SIG is where this product is being developed.
  • A third place which would sit between the CentOS Automotive SIG and the product. This is a public, in development, version of the product.

This third point is what we would like to present to you today: the Automotive Stream Distribution (AutoSD).

The Automotive Stream Distribution is an upstream to the Red Hat automotive product, just as CentOS Stream is to RHEL. The Automotive Stream Distribution will be based on CentOS Stream with a few divergences where it makes sense/is required. The first of these divergences will be the Linux kernel. AutoSD will rely on the kernel-automotive package rather than CentOS Stream's kernel package.

So the Automotive SIG will be the place where anyone and everyone can join, contribute, and experiment (e.g., the SIG supports enabling new hardware on the kernel) and benefit from the infrastructure developed around this SIG, but without engaging Red Hat (new hardware enabled in the SIG does not mean it would automatically become part of Red Hat's automotive product.)

As a binary distribution, AutoSD will thus be the place where the community, customers and/or partners will be able to see what will land in the automotive product down the line. Like CentOS Stream, Automotive Stream Distribution will be opened to contributions, using similar mechanisms.

The next Automotive SIG meeting will be held on Wednesday March 2nd at 15:00 UTC. We will discuss the Automotive Stream Distribution in that meeting, so join us!

New CentOS Director – Amy Marrich

March 01, 2022 12:05 AM

Every six months (in January and August) the CentOS board has the opportunity to reelect, or replace half of the directors. This staggered approach was adopted so that we are never in a situation where the entire board (or even a significant majority) is replaced, leaving no experienced directors.

In the January 2022 board meeting, the CentOS Board selected two new directors to replace outgoing directors Jim Perrin and Karanbir Singh - Celeste Lyn Paul and Amy Marrich. In the February meeting, these new directors attended as full members for the first time.

In this interview I speak with Amy about her road to the board, and what she brings to the conversation.

You can watch the full interview at https://youtu.be/xKtno_DTsaU

I want to start with a personal thank you to Amy for being willing to serve in this role. It’s a huge service to the community, and can be a bit thankless.

Amy is a Principal Technical Marketing Manager at Red Hat, but views her role on the board as representing the community, not Red Hat. This is, of course, typical of our directors, as you have heard in other director interviews. If there’s something that the community wants, it will be her position to support the community over Red Hat’s needs or preferences.

She’s been a long time CentOS user, and has been involved in the Cloud SIG for some time.

She has a history of board experience, as she also serves on the OpenInfra Foundation Board of Directors. As such, she brings a lot of experience and openness to this new role.

Amy observes that while the position on the OpenInfra board is nominated and elected by the whole community, the CentOS Board is nominated by the community, but elected by the sitting board.

She hopes to bring more openness to the CentOS project, and cites the OpenInfra “Four Opens” (Open Source, Open Design, Open Development, Open Community) as inspiration for this.

Amy is particularly proud of going from being an individual contributor on projects to a position of leadership, and hopes to help others make that same journey.

Asked about her visions for the coming board term, she mentions a focus on more openness and transparency around the governance process. She mentions an interest in looking into open community elections of future boards, if the community is interested in this.

She empasized the need to work every more closely with the Fedora project, and the RHEL product, so that user contributions to each part of this project family are seamless and consistent, and don’t require different setups and process for each.

Additionally, anything we can take advantage of that’s already present in the Fedora community - like Badges! - we should, to increase cross-community membership and participation.

Her role on the Cloud SIG gives her insight into how SIGs work, and she mentioned having clear process and documentation around SIGs to make community building easier, and more accessible to beginners. She also mentions a desire to make SIGs more welcoming to other projects - for example, having more than just RDO/OpenStack in the Cloud SIG.

SIGs, too, have a responsibility to communicate with the Fedora project, so that parallel efforts in Fedora (eg, the Fedora Cloud SIG) are not fighting for volunteer effort, but can work together on shared goals.

When we introduced the Code of Conduct, Amy expressed interest in working further on mediation and enforcement. She spoke about the need to coordinate this, took with Fedora, since we share an authentication system and so decisions in one project directly effect the other project. She talked of making a joint team that discusses CoC complaints and how action is taking on those complaints.

Finally, she speaks about a need for better education and documentation around CentOS Stream to continue to help the community to understand the benefits of CentOS Stream and further address the confusion and frustration around the end of the CentOS Linux distribution last year.

Once again, we thank Amy for her willingness to serve, and look forward to her influence on the project in the coming years.

New CentOS Director – Celeste Lyn Paul

February 22, 2022 05:55 PM

Every six months (in January and August) the CentOS board has the opportunity to reelect, or replace half of the directors. This staggered approach was adopted so that we are never in a situation where the entire board (or even a significant majority) is replaced, leaving no experienced directors.

In the January 2022 board meeting, the CentOS Board selected two new directors to replace outgoing directors Jim Perrin and Karanbir Singh - Celeste Lyn Paul and Amy Marrich. In the February meeting, these new directors attended as full members for the first time.

Last week I had the pleasure of speaking with Celeste about how her journey has brought her here, and her vision for her time on the board.

A video of this interview is on YouTube.

Celeste just recently started at Mitre, but over the past 2 decades has had a variety of educational and government positions.

Celeste has several art degrees, which informed the usability and human factors work that she did early in her open source career, which was for the KDE project, and extended to the KUbuntu projects. She was very instrumental in the usability project in KDE, which wasn’t just focused on the desktop environment, but worked with different distributions to understand how they were setting default preferences for users to make sure the KDE user experience worked well with what they were working on the core project. That allowed her to get to know how distributions worked, but also how upstream and downstream interact with each other.

She also got to work with printer vendors, and other commercial entities, that contribute to open source, but are not pure open source, to see how the whole ecosystem works.

She worked in user experience and human factors field in the commercial sector for about 10 years, and then began graduate school, where she worked on a PhD in human-centered computing, which is a field that combines computer science, psychology, and design, where you understand how humans interact with technology, and technology interacts with humans.

She joined the department of defense, where she did research looking at visualization and analytics, understanding how people interact with technology, or use technology to interact with data. That’s also where she started getting interested in cybersecurity.

She is now at the MITRE corporation, where she is a principle cybersecurity engineer.

I asked Celeste what her vision is for the coming year (or, hopefully, years!) on the CentOS board. She again emphasized user experience and usability. As compared to 15 or 20 years ago, when usability was not a high priority in open source software, today everyone recognizes the importance of usability and user experience. But whenever new technology is introduced, you have to understand how that impacts users. There’s always some kind of design that needs to be done. Ensuring that there’s a healthy usability and design community is important to her.

There’s also the business aspect of how upstream and downstream interact with each other. There have, of course, been recent changes with CentOS and how we interact with RHEL and Fedora. Ensuring that we maintain a healthy community, and everyone understands what their roles are and how to contribute, is important for the longevity of the project.

Celeste is also a university instructor, and feels that this keeps her connected with the learning process, which gives insight into how beginning technology users interact with technology, which, in turn, is very informative in terms of how technology should be designed. There can be a tendency for us to get stuck in seeing the world how it was when we, ourselves, started, and lose sight of the perspective of today’s audiences.

And her work in government has taught her a lot of leadership skills, and especially around achieving consensus and resolving conflict in diverse groups of stakeholders.

On behalf of the CentOS community, I want to welcome Celeste to the board, and I look forward to what the board will accomplish in the coming year.

February 2022 Newsletter

Project News

FOSDEM Dojo

CentOS hosted its annual FOSDEM Dojo. This Dojo was once again virtual. If you missed the Dojo, or you just want to watch it again, all of the videos (and some of the slides) are available on the Dojo wiki page.

Also, Aleksandra Fedorova gave a talk at FOSDEM called CentOS Stream: stable and continuous. This excellent talk went into details of how CentOS is actually built.

CentOS Linux 8

Following on the EOL of CentOS Linux 8 last year, the packages for CentOS Linux 8 were removed from the mirror network and placed in the vault at the end of January. If you still need to migrate from CentOS Linux 8 to CentOS Stream 8, see the updated instructions on centos.org.

SIG Reports

Special Interest Groups (SIGs) are the most interesting part of the CentOS project - this is where people build value on top of the CentOS platform. SIGs report quarterly on what they’ve been up to. Here are this month’s reports.

Cloud

Purpose

The Cloud SIG is responsible for packaging and maintaining different FOSS based Private cloud infrastructure applications that one can install and run natively on CentOS.

Releases and Packages

Retirement of CentOS 8

The Cloud SIG has been working on the removal of all jobs and repositories that were utilizing CentOS 8 and moving any remaining jobs to CentOS Stream 8.

Preparation for CentOS Stream 9
The Cloud SIG has been working with the OpenStack Technical Committee and community to coordinate the Yoga release, planned for March 2022, to be on CentOS Stream 9. To achieve this goal, some preparations tasks are being carried out in the RDO Project:

  • OpenStack dependencies have been built for CentOS Stream 9 and preparation to build OpenStack Yoga versions is in progress.
  • Those packages are being validated to find potential issues early, report them, and propose fixes when possible.
  • Coordination with upstream projects that require relevant changes to support the new CentOS Stream.

Meetings and communication

The periodic meeting has been rescheduled from the first Thursday of the month to the second Thursday of the month at 1500 UTC in #centos-meeting. This move was made to alleviate a scheduling overlap with the Fedora Cloud SiG and encourage cross project collaboration.

NFV

Purpose

The CentOS NFV (Network Function Virtualization) SIG provides a CentOS-based stack that will serve as a platform for the deployment and testing of virtual network functions (VNFs) and NFV component packages on compliant CentOS platform.

Membership Update

No changes.

Overall update

NFV SIG keeps updating openvswitch 2.13, 2.15 and 2.16 and OVN for CentOS Stream 8 and CentOS Stream 9.

Packages openvswitch2.15, openvswitch2.16 and ovn-2021 have been pushed to official CentOS Stream 9 mirrors and are available for users.

Issues for the Board

No issues to report to the Board.

Storage

Purpose

The Storage SIG is a collection of like-minded individuals coming together to ensure that CentOS is a suitable platform for many different storage solutions. This group will ensure that all Open Source storage options seeking to utilize CentOS as a delivery platform have a voice in packaging, orchestration, deployment, and related work.

Package Updates

CentOS 7:

  • NFS-Ganesha-4.0 and (lib)ntirpc-4.0 have been released.

CentOS 8:

  • NFS-Ganesha-4.0 and (lib)ntirpc-4.0 have been released.
  • Have asked for build+release of centos-release-ceph-quincy for the upcoming release.
  • Have asked for build+release of centos-release-nfs-ganesha4.

CentOS Stream 8:

  • Ceph Pacific and the related cephadm package v16.2.7 has been released
  • NFS-Ganesha-4.0 and (lib)ntirpc-4.0 have been released.
  • Have asked for build+release of centos-release-ceph-quincy for the upcoming release.
  • Have asked for build+release of centos-release-nfs-ganesha4.

CentOS Stream 9:

  • Ceph Pacific and the related cephadm package v16.2.7 has been released
  • NFS-Ganesha-4.0 and (lib)ntirpc-4.0 have been released.

  • Centos-release-nfs-ganesha4 has been released.

Misc:

  • cephadm subpackage was unbundled from ceph on stream-9 to support ceph’s upstream CI facility. Francesco Pantano (fmount) builds the cephadm package.
  • The OpenStack upstream CI promoted Ceph pacific v16.2.7 on both stream-8 and stream-9 with the related cephadm version.

Messaging

Purpose

The Messaging SIG is responsible for packaging and maintaining messaging related projects to be consumed e.g by the OpsTools SIG or the Cloud SIG.

Membership Update

No change. As always, more hands would be helpful.

Overall update

We have rebuilt and refreshed packages for CentOS Stream 8.

Issues for the Board

None to bring forward at the moment.

    • Thomas: Sorry restricted issue (due to content) to board members, it was missing from above list
  • Discussion around removing Official obsoletes images from the Marketplace (no decision yet)

    • The Board believes that old, unmaintained images (eg Official CL6 images, not third party provided images) be removed from cloud vendors. Send action to CPE infra team? (Rich will open ticket)
    • Such a removal must be clearly messaged/announced on official channels
    • Do cloud providers provide a way to pull down an image for new users, but have existing users of a published image still have access to it.
    • Johnny offers to send a message to centos-devel about retiring cloud images, and gauge community sentiment on that
    • Bex: make it clear images are deprecated in the meanwhile for Humans.
    • Reach to Karanbir for AWS access (el7 ? el8 ?)
  • Propose few new slots for the meeting when new directors are added to the mailing list. #ACTION on Thomas.

CentOS Community Newsletter, January 2022

January 14, 2022 04:06 PM

January 2022 Newsletter

Project News

Update 2022-02-01: These instructions no longer work since the packages were moved from the mirror network to the vault. See the CentOS 8 section of the CentOS Stream page for current instructions.

The big news, of course, is that CentOS Linux 8 reached End Of Life on Friday, December 31, 2021. The CentOS Project recommends that you migrate existing CentOS Linux 8 installations to CentOS Stream:

dnf swap centos-linux-repos centos-stream-repos
dnf distro-sync

Upcoming events

The first CentOS Dojo of 2022 is scheduled for February 3rd and 4th, immediately before the first day of FOSDEM 2022. We expect to publish the schedule to the event wiki page by the time you read this newsletter. The event will be held online, and registration is free! Join us for two days of CentOS content and networking.

SIG Reports

Special Interest Groups (SIGs) are the most interesting part of the CentOS project - this is where people build value on top of the CentOS platform. SIGs report quarterly on what they’ve been up to. Here’s this month’s reports.

Software Collections

Purpose

Provide packages and support for both Red Hat and community Software collections.

Releases

RHSCL-3.8 – A new Red Hat Software Collections were released for RHEL 7 and subsequently made available for CentOS 7.

The following collections are now available:

  • Developer Tollset 11 (devtoolset-11)
  • Nginx 12.0 (rh-nginx120)
  • Redis 6 (rh-redis6)

Health and activity

Given that there are no plans for supporting Software Collections in newer RHEL and/or CentOS Stream, this SIG is now effectively in a “sunset” phase.

Regular rebuilds and updates of both existing and new collections are still planned, but no other activity is expected.

We also expect that the SIG will cease its activity around the EOL date of CentOS 7 (June 2024).

Kmods SIG

This report covers work that happened since last report. The previous report can be found here.

Purpose

Packaging and maintaining kernel modules for CentOS Stream and Enterprise Linux.

Membership Update

No SIG members have been added since last report.

We welcome anybody that’s interested and willing to do work within the scope of the SIG to join and contribute.

Support for CentOS Stream 9

The Kmods SIG recently started building kernel modules for CentOS Stream 9. In case you are missing a particular kernel module in CentOS Stream 9, you can let us know here.

Support for EL8

The Kmods SIG continues to provide packages for EL8, i.e. RHEL 8 and any of its derivatives, even though CentOS Linux 8 went EOL. This can be achieved thanks to RHEL 8 buildroots being available in CBS. We plan to do the same for RHEL 9 once released and available in CBS.

New Packages

See Kmods SIG’s documentation for lists of available packages. This docuementation also provides further information, e.g. how to enable the Kmods SIG’s repositories.

New packages released since last report:

  • NTFS3

Note that the kernel modules provided by the Kmods SIG are currently not signed with a private key. Hence it is required to disable Secure Boot to be able to use any of these kernel modules.

Please report any issues with these packages in the corresponding project on pagure.io or here in case the issue is not related to a particular package.

Health and Activity

The Kmods SIG maintains a healthy development pace.

Communication

Regular meetings are scheduled every two weeks (on even weeks) on Monday 1600 UTC in #centos-meeting. Everyone is welcome to join!

You can also get in touch with SIG members at any time in #centos-kmods.

Open Issues

Signing kernel modules: This requires collaboration and further discussion with Infra SIG. Especially about how to securely store a SIG specific key that can be used in CBS, but is not accessible by any unauthorized person.

Driver Disks: The SIG would like to provide Driver Disks required to install CentOS Stream on unsupported hardware. The current state can be tracked here.

Issues for the Board

We have no issues to bring to the board’s attention at this time.

Hyperscale

The Hyperscale SIG has posted their quarterly report on the CentOS blog.

Automotive

Membership update

This SIG does not have a formal membership process. The mailing list currently has 77 subscribers representing at least yy companies. I have been asked to act as chair for the first few months in order to stabilize the SIG.

Releases

The SIG is not yet creating builds or publishing releases, but we are very close to doing so at this point; see the report below.

Health report and general activity

The SIG has had two public meetings per month, one formal and one informal “office hours”, each with 25-40 attendees representing 7-10 separate organizations. We feel this is a good start at corporate community diversity but will continue to work toward a community-driven project. This SIG is intended to be a community effort with contributions and shared benefits from all participants.

Several RH employees made the first contribution to the project as well as the infrastructure required to build and test it. We now occupy a gitlab repository building software regularly, with build instructions provided, and we are on track for a downloadable release in Q1 2022.

This is a high-level summary of current activity from our technical lead:

  • The work keeps on going at: https://gitlab.com/redhat/automotive/automotive-sig
  • We have created manifests in that repository that can be used with OSBuild to
    create a number of images.
  • We currently support:
    • qemu and raspberry pi
    • x86_64 and aarch64,
    • ostree-based (default) and non-ostree-based
    • booting via uefi of by-passing it and booting directly the kernel
  • We then have 3 images
    • minimal
    • osbuilder (containing the tools allowing to build images with osbuild)
    • neptune (demo image with a graphical interface running the demo app:
      neptune)
  • The OSBuild manifests have been streamed-line and simplified a lot. If you have
    not look at them in a while have a look !
  • We have also added a mechanism to easily build images from within a virtual
    machine, which makes it easier to build images without root privileges.
  • The VM created for the step just above (^) can also be migrated to a different
    system, thus allowing to build more easily in a different architecture.
  • Instructions on how to build images have also been greatly simplified
    The doc at: https://sigs.centos.org/automotive/building/ is up to date
  • We have a kernel-auto package based on the CentOS-Stream package and with the
    Real-Time patches included
  • We have a few koji tags set-up for the SIG, the kernel-auto is the main
    beneficiary of them (with a couple of other RT related packages)
  • We are working on automatically building some of our sample images and making
    them available.
    A few of them can be found at: https://pingou.fedorapeople.org/images/ but
    this is a temporary location and they are now over a month old.
  • We have been sending weekly updates to the SIG mailing list on a regular
    cadence and will try to continue doing it.

Board Election

We are delighted to announce that in the January Board of Directors meeting, we selected two new directors: Amy Marrich and Celeste Lyn Paul. Please join us in welcoming them.

As you are aware, Jim Perrin and Karanbir Singh have stepped down at the expiration of their board term, and we thank them for their many years of service.

You will no doubt hear more from them in the coming days. Welcome, Amy and Celeste, and thank you for being willing to take on this important role in our community.

Community Manager

It’s with some amount of sadness that I, personally, announce that I (Rich Bowen) will be stepping out of the community manager role in the coming weeks. I will be replaced in that role by Shaun McCance, who has a great deal of experience in open source communities. Please welcome Shaun, and do what you can to help him succeed in his new role.

Until next time …

While this newsletter is very late this month, that’s not unusual for January. I hope that you all have a wonderful new year, and that we see each of you stepping up in new ways in the CentOS community this coming year.

    • Proposal: Remove extra red tape from process to get packages into -extras repo
    • SIG-like structure for the repo, with SIG chairs as members
    • Members could tag packages for release when they’re ready
    • Will proceed unless there are objections expressed
    • What do we do about third-party repos like EPEL?
    • Need a policy drafted for this.
      • Policy on retiring unmaintained repos
    • Pat&Davide: document the process (and for SIGs) so they are well informed
      • Brian: yes
    • Tru : How do you resolve conflicts ?
      • Brian: just for -release packages so likely no conflicts
      • Tru: Concerned also about conflicts with third-party repos
    • Davide: would the infra SIG be a good parent organization?
    • Bex: reporting on how many releases are updating their repo defs (and what that means in context) might be a useful stat.
    • Davide: finding out how many folks are downstream consumers of a SIG Repo def could help identify a general number of users (which could be handy).
    • Move forward with the proposal and document it in the SIG Guide + above comments

On going discussion

  • Secure boot and SIGs (ie, issue #67 below)
    • SIGs want to ship content that needs to be signed
    • Signing with personal keys results in a terrible user experience
    • Options
      1. Just use project key
      2. Make a separate key for these artifacts, and get this added to the shim
    • Pat: preference for 2/ - separate volonteers effort
    • Brian: For the Infra, figure out a long term gov for people interacting with Microsoft. Trusted set of people to manage keys.
    • Davide: Could be centralized for all SIGs ? Does it need to be someone at RH ?
    • Bex: Board perspective on why having all the released signed by the same key could be a problem ? Safeguard at the SIG acceptance level ?
    • Neal : Delegate key that can be removed / Think about users perspective for booting things in an easy way
    • Understand how delegate key and shim can be done ? Brian is happy to follow up the different technical questions.
    • Bex : Write a detailed proposal and bring it to Red Hat.
    • Neal: There’s a ticket for this (CS9 secureboot ?) - https://bugzilla.redhat.com/show_bug.cgi?id=2027505
    • Reasonnable to target CS9 only if need be.

SIG Reports

CentOS Hyperscale SIG Quarterly Report for 2021Q4

January 10, 2022 04:31 PM

CentOS Hyperscale SIG Quarterly Report for 2021Q4

This report covers work that happened between October 2nd and December 31st. For previous work, see the 2021Q3 report.

Purpose

The Hyperscale SIG focuses on enabling CentOS Stream deployment on large-scale infrastructures and facilitating collaboration on packages and tooling.

Membership update

Since the last update, the SIG gained two new members (Jack Aboutboul and David Duncan).

We welcome anybody that’s interested and willing to do work within the scope of the SIG to join and contribute. See the membership section on the wiki for the current members list and how to join.

Releases and Packages

Unless otherwise specified, packages are available in our main repository, which can be enabled with dnf install centos-hyperscale-release. Please report any issues with these packages on our package-bugs tracker.

CentOS Stream 9

CentOS Stream 9 is now available and Hyperscale tags have been setup in CBS to build and release packages for it. As of now, we have released systemd and kpatch in our main repository, plus btrfs-progs and a kernel in our experimental repository. We have more packages and features targeting CentOS Stream 9 specifically planned for the near future. Going forward, we expect to continue building packages for both CentOS Stream 8 and CentOS Stream 9 in parallel.

The SIG also emphasizes contributing to CentOS Stream 9 itself whenever possible. As a result, SIG members have made several improvements to CentOS Stream 9.

The Hyperscale SIG is responsible for the following features in CentOS Stream 9, most of which have been contributed in the last quarter:

  • Addition of the systemd-oomd package with useful default configuration
  • Packaging macros for third-party NGINX modules as RPMs
  • PipeWire with WirePlumber and JACK compatibility for the audio subsystem
  • Wayland support for the GNOME Classic session
  • sdl12-compat package replaced the SDL package
  • SDL2 upgraded with proper support for GNOME Wayland

These features have been partially or fully developed by SIG members in Fedora Linux and backported to CentOS Stream 9 for the benefit of the Enterprise Linux community.

Documentation

We have continued fleshing out our user documentation website. Among other things, we have added an explicit versioning policy for our packages, documented our systemd release process and compiled a reference list of Hyperscale-related conference talks.

As previously mentioned, we would very much welcome any feedback and contributions you might have for this documentation.

systemd

The latest version in the Hyperscale SIG continues to be systemd 249. Since the last update we have re-enabled systemd-repart and backported a fix for BPF cgroup controller realization. We now also compile systemd without support for iptables, thus defaulting to nftables, in line with the Fedora packaging. This has allowed us to create builds of systemd 249 for CentOS Stream 9.

In order to support systemd builds, our meson backport has also been updated to 0.58.2.

Compression libraries

We have branched and updated lz4 to 1.9.3 and zstd to 1.5.0. Because these libraries are ABI and API compatible, we were able to push these updates without requiring additonal rebuilds of downward dependencies.

Kernel

CentOS Stream 9

Neal Gompa has started building an experimental kernel for CentOS Stream Hyperscale 9 based on the CentOS Stream/RHEL 9 kernel sources. Initial kernel builds have been released to the experimental repository. As part of this effort, he has been working with the RHEL kernel developers on developing the workflow for external (that is, non-Red Hat) contributors and has begun contributing to the RHEL kernel.

We are also collaborating with the CentOS Kmods SIG to assist in enablement of the necessary support modules in the RHEL kernel to offer Btrfs as a kernel module package for RHEL 9, for those using RHEL 9 or derivatives and need the official RHEL kernel. As part of this, we intend to contribute community maintenance of Btrfs in the RHEL kernel tree for our kernel and the Kmods SIG to carve out and build as a kernel module package.

CentOS Stream 8

The CentOS 8 kernel has remained at 5.12 while Justin Vreeland looks into issues showing up in the bpf selftest during aarch64 builds. Justin plans to have it sync’d with the CentOS Stream 9 kernel Neal has been working on by the end of Q1 2022.

Live media

We started work on getting the necessary image build tools shipped in EPEL 9 to start offering live media based on CentOS Stream 9. The livecd-tools package is currently blocked on dumpet, which has a stalled package branch request for EPEL. The appliance-tools package is blocked on livecd-tools in EPEL. The kiwi package is currently blocked on Red Hat shipping mtools on all architectures. This should be resolved once the next CentOS Stream 9 compose is released and imported into Fedora Koji for EPEL 9.

DNF/RPM stack with CoW support

We have rebased the Copy-on-Write packaging stack in the experimental repository to match the latest updates that landed in CentOS Steam 8 proper.

Health and Activity

The SIG continues to maintain a healthy development pace.

Meetings

The SIG holds regular bi-weekly meetings on Wednesdays at 16:00 UTC. Meetings are logged and the minutes for past meetings are available.

The SIG uses the #centos-hyperscale IRC channel for ad-hoc communication and work coordination, and the centos-devel mailing list for async discussions and announcements. The SIG also holds open monthly video conference sessions to promote collaboration and social interaction.

Conference talks

Last quarter, Davide Cavalca and Neal Gompa presented an update on SIG activities at CentOS Dojo, October 2021 (slides, video). Hyperscale SIG work was also covered in Building the future with CentOS Stream at the Red Hat mini-theater during Supercomputing 2021.

This year, we’ll be presenting another update on SIG activites at CentOS Dojo, FOSDEM 2022. SIG-adjacent talk proposals have also been submitted to DevConf.cz 2022 and SCALE 19x.

Planned work

The SIG tracks pending work as issues on our Pagure repository. Notable projects currently in flight include:

  • using CBS to build our spin images
  • shipping an updated QEMU package in EPEL
  • integrate btrfs transactional updates as an optional feature
  • setup a continuous build pipeline for the container image on the CentOS CI infrastructure
  • build a set of Hyperscale-enabled Cloud images

Issues for the Board

We have no issues to bring to the board’s attention at this time.

Combining multiples audio sinks with PulseAudio on CentOS Stream 8

January 05, 2022 11:00 PM

During winter break/holidays, I offered myself a new Bass and I mentioned this to one of my friends, who also offered himself a new guitar. As pandemic is still ongoing, he decided to just quickly record himself (video shot) and posted me the link and asked me to do the same.

Then became the simple problem to solve : while I have two nice Fender Amplifiers (Mustang LT and Rumble LT) that are recognized natively by linux kernel on CentOS Stream 8 as valid input sources, I wanted to also combine that with a backing track (something playing on my computer, basically a youtube stream) and record that easily with the simple Cheese video recording app present by default in gnome.

I had so a look at PulseAudio and see if that was easily possible to combine the monitor device (basically the sound coming from your pc/speaker when you play something) with my amplifier as different input, and so then record in one shot that as a new stream/input that Cheese would transparently use (Cheese lets you specific a webcam but nothing wrt sound/microphone/input device)

Here is the solution :

  • creating a new sink with the module-null-sink pulseaudio module
  • adding some inputs (basically the main audio .monitor device and my amplifier) to that sink with the module-loopback pulseaudio module
  • creating then a "fake" stream that can be used as input device (like a microphone) using the module-remap-source

For example, when my Guitar amplifier is usb connected , it's shown like this :

pacmd list-sources | egrep '(^\s+name: .*)|(^\s+device.description = .*)'

    name: <alsa_output.usb-Lenovo_ThinkPad_Thunderbolt_3_Dock_USB_Audio_000000000000-00.analog-stereo.monitor>
        device.description = "Monitor of ThinkPad Thunderbolt 3 Dock USB Audio Analog Stereo"
    name: <alsa_input.usb-Lenovo_ThinkPad_Thunderbolt_3_Dock_USB_Audio_000000000000-00.mono-fallback>
        device.description = "ThinkPad Thunderbolt 3 Dock USB Audio Mono"
    name: <alsa_input.usb-046d_HD_Pro_Webcam_C920_F4525F9F-02.analog-stereo>
        device.description = "HD Pro Webcam C920 Analog Stereo"
    name: <alsa_input.usb-MICE_MICROPHONE_USB_MICROPHONE_201308-00.mono-fallback>
        device.description = "Blue Snowball Mono"
    name: <alsa_output.pci-0000_00_1f.3.analog-stereo.monitor>
        device.description = "Monitor of Built-in Audio Analog Stereo"
    name: <alsa_input.pci-0000_00_1f.3.analog-stereo>
        device.description = "Built-in Audio Analog Stereo"
    name: <alsa_input.usb-FMIC_Mustang_LT_25_00000000001A-02.analog-stereo>
        device.description = "Mustang LT 25 Analog Stereo"

Now that we have the full name, we can use a simple bash wrapper script to either create a new input , based on bass/guitar amp preference, and this is the script :

Now that we have a script, I can just call it like that, example for my Guitar amp :

 ./pulse-audio-amp-combine -i guitar
[+] ./pulse-audio-amp-combine -> Fender Mustang amplifier selected
[+] ./pulse-audio-amp-combine -> Adding new sink [monitor-and-amp]
26
[+] ./pulse-audio-amp-combine -> Adding monitor device [alsa_output.usb-Lenovo_ThinkPad_Thunderbolt_3_Dock_USB_Audio_000000000000-00.analog-stereo.monitor] to created sink [monitor-and-amp]
27
[+] ./pulse-audio-amp-combine -> Adding external amplifier [alsa_input.usb-FMIC_Mustang_LT_25_00000000001A-02.analog-stereo] to created sink [monitor-and-amp]
28
[+] ./pulse-audio-amp-combine -> Creating now new virtual input [mustang-combined] to be used as input for recording
29

And it then appears as new input that I can select as default under gnome :

gnome-settings

I also have rebuilt/installed pavucontrol application, which can be handy to visualize all the streams and you can also control the volume in the recording tab :

pavucontrol-recording

You can then have lower input from the audio you're playing on laptop (for example a backing track found on youtube but anything played on laptop is going to the monitor device) but YMMV and you have to do a quick test first with your other input (my amp+instrument in my case)

Once done, you can use any app like audacity or cheese or else to just record. Probably easier and faster than complex (but more professional though) systems around Jack. As said, it's just to quickly record something and combine streams/sinks all together, nothing like a DAW system :-)

CentOS Community Newsletter: December 2021

December 07, 2021 02:06 PM

Dear CentOS enthusiast,

As we approach the end of 2021, I wanted to thank all of you who have worked so hard this year towards the betterment of the project. This year we've made governance more transparent, welcomed several new SIGs, made big strides in consolidating infrastructure with Fedora where it made sense, and begun to return to in-person events. We could not have done this without the passion and hard work of the project community. Thank you.

Project News

CentOS Linux 8 End Of Life

Update 2022-02-01: These instructions no longer work since the packages were moved from the mirror network to the vault. See the CentOS 8 section of the CentOS Stream page for current instructions.

This is your final notice that CentOS Linux 8 reaches its end of life on December 31st. The CentOS Project recommends that you migrate your existing CentOS Linux 8 installations to CentOS Stream 8:

dnf swap centos-linux-repos centos-stream-repos
dnf distro-sync

And, of course, if you cannot, or do not wish to, use CentOS Stream, several rebuild projects have sprung up this year to fill that space.

CentOS Stream 9 Launch

The CentOS Project is delighted to announce the availability of CentOS Stream 9, the latest major release of the CentOS Stream distribution.

With CentOS Stream 9, you can influence the development of RHEL (Red Hat Enterprise Linux) 9 with patches, bug reports, and discussion. What goes into CentOS Stream 9 is an indication of what you’ll see in the next minor release of RHEL, so it’s a great way to get ahead of the game if you’re developing something for deployment on RHEL.

You can read more about CentOS Stream 9 in the announcement blog post and on the new centos.org/stream9 web page, which we intend to be an ongoing chronicle of what’s happening in that project.

New Website Design!

Along with the launch of CentOS Stream 9 last week, we are delighted to show you the new website design that the Artwork SIG, lead by Alain Delgado, has been working on this year. For the first time in years we have a unified theme across all of our important web properties, incuding centos.org, this blog, the mailing list archives, and will come to more of our websites over the coming weeks and months.

Board nominations and election timeline

The CentOS Board of Directors has one-year terms, with half of the terms expiring in February, and the other half in August, so that there’s always some experienced directors at any given time, in the unlikey event that all directors were to step down in a given term.

As such, we’re coming up on another Board term starting in February, and the call for nominations has been open for about a month, and in the January board meeting, the board will select the replacement for the two directors who have indicated that they will step down at the end of this term. Nominations are now closed, so that the directors can consider their options over the next few weeks.

We look forward to welcoming two new directors in the February board meeting, and introducing them to you.

EPEL 9 is now ready for developers to begin contributing

Carl George writes: “On behalf of the EPEL Steering Committee, I’m pleased to announce the availability of EPEL 9. This is the culmination of five months of work between the EPEL Steering Committee, the Fedora Infrastructure and Release Engineering team, and other contributors. Package maintainers can now request dist-git branches, trigger Koji builds, and submit Bodhi updates for EPEL 9 packages.” More details are on the Fedora community blog

Other community updates

Events

Over the past few weeks we’ve been present at two events, where we had great conversations with users and developers of CentOS Linux and CentOS Stream.

SC21 - Supercomputing

SC21 was held in St. Louis at the end of November. We had the opportunity to talk with many universities and research organizations who are using CentOS, RHEL, and various other rebuilds, in their supercomputing infrastructure.

Also at the event, CentOS community members Neal Gompa and Davide Cavalca gave a presentation about the Hyperscale SIG, and SIGs in general, focusing on the opportunity to contribute to the entire Enterprise Linux ecosystem.

OLF (Ohio LinuxFest)

We were delighted to sponsor OLF last weekend, and talk with the Open/Libre/Free software enthusiasts of Central Ohio and surrounding areas.

The event, which was previously named Ohio LinuxFest, rebranded this year to Open/Libre/Free to reflect that it’s about so much more than just Linux. We were very pleased to see it come back to being an in-person event for its 19th year, and look forward to attending for many years to come.

FOSDEM + Dojo

FOSDEM has announced that they will be online again this year. And, as usual, we’ll be holding a CentOS Dojo on the day leading up to FOSDEM. This year, that means that it will be held February 3rd and 4th. The extra day is just so that we don’t have multiple tracks at the same time, and to be friendly to multiple time zones.

The Call for Presentations (CFP) is now open, and will be open until January 9th. (See the event page for details.)

SCaLE

We are tentatively planning to be present at the upcoming SCaLE in Pasadena, March 3-6 2022.

Event Recommendations/Requests

If you have an event that you’d like to recommend to us, please reach out to the CentOS-Promo mailing list to suggest it.

Also, if you would like to volunteer a location for an in-person CentOS Dojo in 2022, we would love to have some events at new places in the coming year.

SIG Reports

CentOS SIGs are smaller groups doing interesting things on top of the CentOS platform. If you’re looking at getting involved in CentOS, SIGs are usually the best place to get started. You can read more about SIGs at the new SIGs website, https://sigs.centos.org/

Each month, several of our SIGs report about what they’ve been up to for the past quarter.

Virtualization

Advanced Virtualization updates

  • AV 8.5.0 packages have been built and already tagged as -release.
    This is the last build of AV on the SIG, as the AV program is now
    obsolete in favor of the regular RHEL stream.

oVirt updates

  • oVirt is now moving the main development platform from
    gerrit.ovirt.org to github.com/oVirt (sbonazzo, 16:07:59)
  • also moving automation from jenkins.ovirt.org to GitHub Actions
  • merged pathces now are triggering builds in copr at
    https://copr.fedorainfracloud.org/coprs/ovirt/ovirt-master-snapshot/
  • oVirt project is planning to release GA builds directly via CentOS
    Virtualization SIG
  • it should make life easier for users and for other distributions
    already rebuilding CentOS Virtualization SIG repos
  • major issues found so far: a huge amount of missing java libraries
    needed to build ovirt-engine and some issue building oVirt Node and
    oVirt Appliance
  • but CentOS Community Build System should work fine once all the
    dependencies will be available
  • oVirt project received contribution for building oVirt Engine on
    aarch64, patch is currently being reviewed
  • some oVirt project developers are now collaborating with OKD
    Virtualization SIG too. Give OKD Virtualization or OKD on oVirt a
    run and let us know how it goes

any other business

  • We are starting a new project to provide packages for Intel TDX in
    the SIG. Currently In early stages, we are still sorting out details
    about the development proceess
  • Packages will be available in virt8s-tdx-devel

CentOS OpsTools SIG Quarterly Report

Sep 01, 2021 - Nov 30, 2021

Purpose

Provide tools and documentation, recommendation and best practices for operators of large infrastructure.

Membership update

Sadly, we did not attract new volunteers to contribute to the SIGs purposes, but at the same time, we didn’t lose any.

Activity

We’ve rebuilt the packages and dependencies for the OpenStack Collectd container for CentOS 9 Stream and CentOS 8 Stream.
Next is to update collectd to version 5.13, which will be released soon.

Issues for the board

Nothing to report.

Until next year …

And that’s a wrap for 2021. From the CentOS Project to you, we wish you a healthy and prosperous new year, and to those who are celebrating a holiday at this time of year, we hope you have a wonderful happy time with your friends and family. We’ll see you next year!

Introducing CentOS Stream 9

December 03, 2021 12:44 PM

The CentOS Project is delighted to announce the availability of CentOS Stream 9, the latest major release of the CentOS Stream distribution.

What’s Great About CentOS Stream

CentOS Stream is Continuous

CentOS Stream is a continuous-delivery distribution providing each point-release of Red Hat Enterprise Linux (RHEL). Before a package is formally introduced to CentOS Stream, it undergoes a battery of tests and checks—both automated and manual—to ensure it meets the stringent standards for inclusion in RHEL. Updates posted to Stream are identical to those posted to the unreleased minor version of RHEL. The aim? For CentOS Stream to be as fundamentally stable as RHEL itself.

To achieve this stability, each major release of Stream starts from a stable release of Fedora Linux—In CentOS Stream 9, this begins with Fedora 34, which is the same code base from which RHEL 9 is built. As updated packages pass testing and meet standards for stability, they are pushed into CentOS Stream as well as the nightly build of RHEL. What CentOS Stream looks like now is what RHEL will look like in the near future.

CentOS Stream is Community

CentOS Stream is developed through collaboration between the CentOS community and the RHEL engineering team. Although many CentOS Stream contributions derive from Red Hat employees, CentOS Stream thrives on community support. CentOS Stream is a stable, reliable platform for open source communities to expand upon, allowing people from all areas and backgrounds to collaborate in an open environment.

Because CentOS Stream ultimately becomes RHEL, contributors also have an opportunity for their work to influence future builds of RHEL; this makes CentOS Stream an ideal environment for creativity and forward-thinking.

Getting CentOS Stream

CentOS Stream can be downloaded as an ISO from our mirrors and is compatible with 64-bit x86 (x86_64 v2+), 64-bit ARM (AArch64), IBM Z (s390x Z14+), and IBM POWER (ppc64le POWER9+) architectures.

Contribute to CentOS Stream

Community is at the heart of the CentOS Project, and there are many ways you can contribute. A list of areas where you can contribute is available on the CentOS Wiki.

Because CentOS Stream is upstream of RHEL, it offers an ideal environment for applications which are designed be deployed in RHEL. We welcome and encourage contributors from all backgrounds—especially those developing for the post-RHEL production stream—to use CentOS Stream to build, test, and deploy the applications that are special to you and to the greater Linux community.

You can also contribute by joining (or creating) a Special Interest Group (SIG) in an area of your interest. Visit the CentOS Wiki to learn more.

Learn More

CentOS Stream is made for you to make it what you want it to be. To learn more about CentOS Stream 9, visit the CentOS Website: centos.org/stream9

Announcing the latest release of CentOS Linux 8 (2111)

November 16, 2021 02:13 PM

We are pleased to announce the general availability of the latest version of CentOS Linux 8. Effectively immediately, this is the current release for CentOS Linux 8 and is tagged as 2111, derived from Red Hat Enterprise Linux 8.5 Source Code.

**PLEASE NOTE:** CentOS Linux 8 will EOL on 31 December 2021. We will handle the EOL as directed by the CentOS Project Board of Directors and detailed here:

https://www.centos.org/centos-linux-eol/

As always, read through the Release Notes at:
http://wiki.centos.org/Manuals/ReleaseNotes/CentOS8.2111
- these notes contain important information about the release and details about some
of the content inside the release from the CentOS QA team. These notes are updated constantly to include issues and incorporate feedback from users.

Remember, you should not be using CentOS Linux 8 in production or you should have a plan to migrate to a different Operating System before 31 December 2021. We will only be doing updates as detailed in the above EOL link.

----------
Updates, Sources, and DebugInfos

Updates released since the upstream release are all posted, across all architectures. We strongly recommend every user apply all updates, including the content released today, on your existing CentOS Linux 8 machine by just running 'dnf update'.

As with all CentOS Linux 8 components, this release was built from sources hosted at git.centos.org. Sources will be available from vault.centos.org in their own dedicated directories to match the corresponding binary RPMs.

Since there is far less traffic to the CentOS source RPMs compared with the binary RPMs, we are not putting this content on the main mirror network. If users wish to mirror this content they can do so using the reposync command available in the yum/dnf-utils package. All CentOS source RPMs are signed with the same key used to sign their binary
counterparts. Developers and end users looking at inspecting and contributing patches to the CentOS Linux distro will find the code hosted at git.centos.org far simpler to work against. Details on how to best consume those are documented along with a quick start at:
http://wiki.centos.org/Sources

Debuginfo packages have been signed and pushed. Yum configs shipped in the new release file will have all the context required for debuginfo to be available on every CentOS Linux install.

This release supersedes all previously released content for CentOS Linux 8, and therefore we highly encourage all users to upgrade their machines. Information on different upgrade strategies and how to handle stale content is included in the Release Notes.

Note that older content, obsoleted by newer versions of the same applications are trim'd off from repos like extras/ and centosplus/

Getting Help

The CentOS ecosystem is sustained by community driven help and guidance. The best place to start for new users is at http://wiki.centos.org/GettingHelp

We are also on social media, you can find the project: on Twitter at :http://twitter.com/CentOS
on Facebook at :https://www.facebook.com/groups/centosproject/
on LinkedIn at :https://www.linkedin.com/groups/22405

And you will find the core team and a majority of the contributors on irc, on irc.libera.chat in #centos ; talking about the finer points of distribution engineering and platform enablement.

----------
Contributors

This release was made possible due to the hard work of many people, foremost on that list are the Red Hat Engineers for producing a great distribution and the CentOS QA team, without them CentOS Linux would look very different. Many of the team went further and beyond expectations to bring this release to you, and I would like to thank everyone for their help.

We are also looking for people to get involved with the QA process in CentOS, if you would like to join this please introduce yourself on the centos-devel list (http://lists.centos.org/mailman/listinfo/centos-devel).

Finally, please join me in thanking the donors who all make this possible for us.

CentOS Linux 7 will be available and maintained until 2024 and CentOS
Stream 8 will also be maintained until that time. Here is how CentOS
Stream is different from CentOS Linux as and EOL information:

https://www.centos.org/cl-vs-cs/

Here is how you can move a machine from CentOS Linux 8 to CentOS Stream 8:

https://www.centos.org/centos-stream/

In closing, this release is very bittersweet for me. I have been involved in the CentOS Linux process and have done the vast majority of releases since the 2004. Moving forward, I will be working as hard as I can to make sure CentOS Stream is the best it can be.

It has been a wild ride, thanks for the memories.

Thanks,
Johnny Hughes
