[Infra] - Planned outage : cbs.centos.org
by Fabian Arrotin 08 Aug '22

08 Aug '22

We recently received some RFEs for new features for our Community Build System (aka https://cbs.centos.org) on our tracker (https://pagure.io/centos-infra/issues), and some were added in upstream koji projects. So we'll upgrade our koji build environment to latest koji version 1.29.1 (and get same version deployed after for Stream build env too) to then be able to track/test new features for SIGs. Migration is scheduled for """"Monday August 8th, 7:00 am UTC time"""". You can convert to local time with $(date -d '2022-08-08 07:00 UTC') The expected "downtime" is estimated to ~5 minutes , time needed for ansible to shutdown kojid builders, upgrade kojihub (cbs.centos.org), run db schema upgrade, restart kojihub and then kojid builders. Thanks for your understanding and patience. on behalf of the Infra team, -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | twitter: @arrfab

CPE Weekly Update – Week 31 2022
by Lenka Segura 05 Aug '22

05 Aug '22

Hi everyone, This is a weekly report from the CPE (Community Platform Engineering) Team. If you have any questions or feedback, please respond to this report or contact us on #redhat-cpe channel on libera.chat (https://libera.chat/). Week: 1st - 5th August 2022 If you wish to read this in form of a blog post, check the post on Fedora community blog: https://communityblog.fedoraproject.org/cpe-weekly-update-week-31-2022 # Highlights of the week ## Infrastructure & Release Engineering Goal of this Initiative ----------------------- Purpose of this team is to take care of day to day business regarding CentOS and Fedora Infrastructure and Fedora release engineering work. It’s responsible for services running in Fedora and CentOS infrastructure and preparing things for the new Fedora release (mirrors, mass branching, new namespaces etc.). The ARC (which is a subset of the team) investigates possible initiatives that CPE might take on. Link to planning board: https://zlopez.fedorapeople.org/I&R-2022-08-03.pdf Link to docs: https://docs.fedoraproject.org/en-US/infra/ Update ------ ### Fedora Infra * Unblocked osbuild in production, should be working now. (Uses script to keep api ip updated in the firewalls) * Ocp4 cluster api uses valid cert not (for webhooks/external oc) * Disabled systemd-oomd in some places (koji hubs in particular) * Barcamp at nest on saturday: https://hackmd.io/MiWdaZXCRDi4LEO1jmyLDg * Some sysadmin-main additions: Nils, Michal, Ryan ### CentOS Infra including CentOS CI * Duffy CI is now live (so hotfixes are also coming, thanks to Nils) * Preparing CBS/koji upgrade to 1.29 (would unblock other RFEs on tracker) ### Release Engineering * FTBFS bugs filed on failing to build packages * Containers: rawhide fixed/updating, updated f35/f36 ## CentOS Stream Goal of this Initiative ----------------------- This initiative is working on CentOS Stream/Emerging RHEL to make this new distribution a reality. The goal of this initiative is to prepare the ecosystem for the new CentOS Stream. Updates ------- * Meetings about and started code, to move module source from git.centos to gitlab. * New ISOs for CentOS Linux 7 for installation that fixes libtimezonemap (and other) issues. * Rewrote the errata announcement scripts for CentOS Linux 7 to use new endpoints after the decommissioning of the API search/rs/ on access.redhat.com. ## EPEL Goal of this initiative ----------------------- Extra Packages for Enterprise Linux (or EPEL) is a Fedora Special Interest Group that creates, maintains, and manages a high quality set of additional packages for Enterprise Linux, including, but not limited to, Red Hat Enterprise Linux (RHEL), CentOS and Scientific Linux (SL), Oracle Linux (OL). EPEL packages are usually based on their Fedora counterparts and will never conflict with or replace packages in the base Enterprise Linux distributions. EPEL uses much of the same infrastructure as Fedora, including buildsystem, bugzilla instance, updates manager, mirror manager and more. Updates ------- * EPEL9 is up to 7127 (+141) packages from 3180 (+97) source packages * Prepared EPEL survey, it will be promoted on FedoraNest * Provided a fix to nagios-plugins-check-updates to improve distro compatibility ## FMN replacement Goal of this initiative ----------------------- FMN (Fedora-Messaging-Notification) is a web application allowing users to create filters on messages sent to (currently) fedmsg and forward these as notifications on to email or IRC. The goal of the initiative is mainly to add fedora-messaging schemas, create a new UI for a better user experience and create a new service to triage incoming messages to reduce the current message delivery lag problem. Community will profit from speedier notifications based on own preferences (IRC, Matrix, Email), unified fedora project to one message service and human-readable results in Datagrepper. Also, CPE tech debt will be significantly reduced by dropping the maintenance of fedmsg altogether. Updates ------- * Frontend auth being developed * Access token and refresh token * Making pages require auth, if user is not authenticated, redirect to login * Backend auth still being developed (tests) * Mockups for UI - bootstrap/HTML/CSS * Agile ceremonies being planned Kindest regards, CPE Team

Alternate Images - Proposed SIG
by Troy Dawson 04 Aug '22

04 Aug '22

Following the CentOS "Setting up a new SIG"[1] instructions I am opening a new topic about creating a new CentOS SIG. I have initially filled out several sections that are in other SIG pages. These are all open for discussion. Goals: The Alternate Images SIG's goal will be to build and provide alternate iso images for CentOS Stream. What is in Scope: - Live Images (Previously known as LiveDVD, LiveCD) -- Examples: --- Live Desktops (KDE / GNOME / XFCE / Mate ) --- Live Rescue - Alternate Install Images -- Examples: --- Minimum install iso (doesn't need the network, but almost as small as the boot.iso) --- KDE install iso (has epel enabled, and packages to install a working kde desktop) - Repo's that are compatible with CentOS Stream, and follow the Fedora licensing policy. What is not in Scope: - Containers - Raw / QCow / AWS - Iso images that are bigger than 4 Gig. (This number can be adjusted after the SIG is formed) - Repo's that are not compatible with CentOS Stream, or do not follow the Fedora licensing policy. Collaboration: We plan on working with various Desktop SIG's, the Fedora minimization team, and any other group that wants custom iso's. Deliverables: - Documentation along with configuration (kickstarts and scripts) that will allow members to create their alternate images. - Alternate images in a publically downloadable area -- Images will be rebuilt, or retired, a minimum of every three months. Leadership: I (Troy Dawson) will be the initial Lead of the SIG. After (or while) the SIG is formed we will decide if we want a co-chair leadership and/or how often the leadership is elected.

Happy Anniversary, CentOS Automotive SIG!
by Jeffrey Osier-Mixon 03 Aug '22

03 Aug '22

Todays' monthly meeting was lightly attended as expected, and we didn't have a lot of technical topics to update, but I did want to send out the one thing we did cover. August marks the 1st anniversary of the CentOS Automotive SIG, and we have accomplished quite a lot over this first year. The first meeting was August 19, 2021, at which time there was no infrastructure at all and the group had just been voted into existence by the CentOS board. Now, one year later, we have a robust repository within the CentOS domain, open to contributions by the public - and indeed we had our first contributor from outside Red Hat over the past month, which is a great example of the value we hope we are bringing to automotive Linux development. In addition to the repositories, we have a strong nightly build structure providing a continuous stream of images that are easy to download and get running via QEMU or on a Raspberry Pi 4. The image uses Stream 9 components with a customized (real time) kernel, a good example of CentOS Stream based development, and a fun and interesting project. Congratulations to everyone involved with the SIG, and thanks again to CentOS for hosting it!

Planned outage : Duffy CI infra migration phase 1 on August 1st
by Fabian Arrotin 27 Jul '22

27 Jul '22

As previously announced in June (see https://lists.centos.org/pipermail/ci-users/2022-June/004547.html and also https://www.youtube.com/watch?v=aqgs-3NnRmA), we'll migrate existing Duffy API service to the new Duffy v3, starting with Phase 1 . Migration is scheduled for """"Monday August 1st 7:00 am UTC time"""". You can convert to local time with $(date -d '2022-08-01 07:00 UTC') The expected API downtime will be under the 60 seconds (DNS TTL). Worth knowing: - new duffy api (in legacy mode) has currently less available nodes, but that will be resolved during the day (see below) - we'll have to wait ~6h (default maximum "lease" time for a test node) to be able to let new duffy api reinstall older seamicro nodes and so be available in the new duffy v3 pool (transitioning from old to new duffy pool) - currently running jobs will continue so to work, but when you'll hit new duffy api endpoint (DNS switch) to "return nodes" it will just answer that session doesn't exist (new one) but it's safe to ignore As soon as new duffy API is available you'll already be able to switch your workflow to new the Duffy API and so use the new features. Tenants/users documentation about how to interact with Duffy is available on https://sigs.centos.org/guide/ci/ (see the Duffy part of that documentation) That means that switching to EC2 nodes will be directly possible. During the day we'll tune the duffy nodepool configuration based on usage metrics. IMPORTANT remark : *only* projects/tenants that opted-in in the last 45 days are currently migrated (api and ssh keys), so if you haven't (yet), you can still opt-in, otherwise all your requests for duffy ephemeral nodes will be declined by new duffy api service next monday. In case of troubles, both Pedro (nick phsmoura) and myself (nick arrfab) will be also present in the #centos-ci irc channel on irc.libera.chat the whole day. Thanks for your understanding and patience. on behalf of the Infra team, -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | twitter: @arrfab

Question on absence of SHA1 in OpenSSL 3.0/Centos 9 stream.
by Nickolay Olshevsky 25 Jul '22

25 Jul '22

Hi, Having SHA1 support removed from the OpenSSL in Centos 9 stream, it is still displayed in the list of supported digest, via CLI `openssl dgst -list` and via library API calls like `EVP_get_digestbyname()` and `EVP_MD_do_all_sorted()`. However, in some cases it would be desirable to know whether particular OpenSSL installation supports SHA1. So, the question - is it done this way by intention and I should look for some workaround, or it is something to get fixed in further package updates? Thanks! -- Best regards, Nickolay Olshevsky o.nickolay(a)gmail.com
