ksplice and CentOS
by Karanbir Singh 25 Sep '25

25 Sep '25

hi guys, lots of people on this list are keen on contributing to the CentOS effort - and one place where we could, as a group of people, make a massive difference is being able to deliver a ksplice upgrade model. A couple of people have started in silo's to try and get something together but I feel it might be a good time to try and see if we can do somethng as a group. Do we have people on the list who find the idea of rebootless kernel upgrades interesting ? Is there some desire to try and make that happen within the CentOS Ecosystem ? - KB

anaconda dependency calculation?
by Nicholas Byrne 04 Aug '25

04 Aug '25

Hi all, I'm trying to find a tool that calculates all dependencies for a specific package or group of packages for use with CentOS 5 (beta) with the intention of putting together a custom single CD build of CentOS 5. With CentOS 4 i used a python script that used the hdrlist module to find all dependencies which borrowed code from a number of sources. I've looked at yumdownloader and how it checks dependencies (using the --resolve option) but if i pass it the list of packages defined in say the Base and the Core yum groups which generally form an absolute minimal install i end up with about 200 packages. If i do a custom install (using beta 1 disks) and deselect everything i end up with over 300 packages. So i'm guessing anaconda calculates dependencies in a slightly different way, can anyone point me to files/code where i should be looking to find out?

forums + portal for {lang}.centos.org sites
by Karanbir Singh 16 Aug '24

16 Aug '24

Hi, Earlier in the evening today Ralph, Fabian and I had a chat about the present state of the language subsites. This email sort of summarises the main issue ( s/w ). We seem to have run into a slight technical hitch with punbb/fluxbb. They dont support LDAP as a backend. And we had decided a few months back that all new rollouts must have ldap backend so we can rollin CentOS-DS / openldap based backend. So we need to look at alternatives, and since the primary focus of these international sites is going be forums : Here is a shortlist ( if there is anything else that people are aware of, please add to this list ) - phpBB - SMF - Fudforum - phorum - fluxbb Requirements: - Must be able to scale ( couple of hundred thousand msgs ) - Must be able to handle ldap auth ( if it cant, whats involved in writing the ldap-auth portion ) - Must address the specific requirements raised by the present www.centos.org forum users ( Can you please fill this section in ? ) - Must support all languages we need ( pure utf8 support would be good ) - Secure - Skin'able Nice to have: - Capable of running multiple instances from a single deployment - responsive community :D Things we will need to do: - Decide on what s/w to use. - Give the ArtWork people enough time to get the look & feel sorted. - Migrate newbb forums from www.centos.org to $system ( hey, english is a language too :D ). - Migrate fr.centos.org into the final s/w - setup {de/es/ja/it/pt_br}.centos.org Actions: Ralph and Fabian are going to work on setting up a test ldap server, once that is online we will then start by installing into our test-vm-farm the various s/w to eval them. If anyone would like to help, please feel free to jump right in. I'll setup a wiki page for this issue, which might be a good place to track progress. -- Karanbir Singh : http://www.karan.org/ : 2522219@icq

CentOS 8 Artwork needed
by Rich Bowen 31 Jan '20

31 Jan '20

To all the artists and designers here, we need your help. With RHEL 8 beta released, we need to start producing artwork for CentOS 8. It's time for the CentOS Artwork SIG, and anyone else that's interested in contributing to this effort, to start working on everything that will be needed for the new release. What we know we need is anaconda artwork, and new desktop backgrounds to replace the current '7' themed stuff. As we dig, we may find more things that need to be updated to the new 8 theme. Additionally, we will need to update some of the assets listed here: https://wiki.centos.org/ArtWork/Identity ... and produce new assets for 8 to be listed here: https://wiki.centos.org/ArtWork/Brand/Logo And, finally, we need someone to step up to lead this effort. While we don't yet know for certain when RHEL 8 will officially release, it's safe to assume that it's soon, and we need your help. -- Rich Bowen - rbowen(a)redhat.com @CentOSProject // @rbowen 859 351 9166

Using mirrorlist in centos-release-* packages
by Anssi Johansson 12 Sep '19

12 Sep '19

Hi, as mentioned in https://lists.centos.org/pipermail/centos-devel/2018-September/016949.html mirrorlist.centos.org has been updated to produce mirror lists for SIG content as well. Some centos-release-* packages have already been modified to use mirrorlist.centos.org instead of mirror.centos.org, but many still point to mirror.centos.org. Most of mirror.centos.org hosts are also used for seeding the 600+ external mirrors we have. By directing some of their download traffic to external mirrors we can offer faster sync speeds for those external mirrors, and for people downloading individual rpms from mirror.centos.org. Second, most of those external mirrors offer faster download speeds to end users than what could be achieved by downloading from mirror.centos.org, so the users will benefit from this change as well. The better geographical coverage does not hurt either. mirror.centos.org nodes are donated servers, and it would be kind to the sponsors to use their bandwidth sparingly. The .repo files should be modified so that the current baseurl line gets commented out and a mirrorlist entry gets added, like this: mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch… #baseurl=http://mirror.centos.org/$contentdir/$releasever/storage/$basearch/gluster-4.1/ Note that mirrorlist.c.o can automatically choose between main and altarch content based on the arch parameter. The repo names are constructed from the repository path by stripping away the architecture and changing any slashes to dashes: sclo/x86_64/rh -> sclo-rh, sclo/x86_64/sclo -> sclo-sclo, paas/x86_64/openshift-origin311 -> paas-openshift-origin311, storage/x86_64/gluster-5 -> storage-gluster-5 etc. You can use 'curl' to check what mirrorlist outputs for your repository. New repos are added to mirrorlist.centos.org automatically once the repository hits mirror.centos.org. That script is currently run every three hours. I guess it could be run more frequently (it's fairly lightweight), but you should give the external mirrors a few hours to sync before announcing your release anyway. You can either submit an update to your current centos-release-* file now, or wait until you need to create a new centos-release-* package for other reasons such as releasing softwarepackage-(version+1) which uses different paths. My recommendation would be to submit an update to your current centos-release-* package, so that you would not need to worry about this when you eventually need to publish a new one for other reasons. We released an updated centos-release package for CentOS AltArch before 7.6.1810 was released for this exact reason, ie. we didn't need to worry about this change at 7.6.1810 release time. Other people (such as bstinson, arrfab and hughesjr) can probably help with creating and publishing an updated centos-release-* package, but the usual tagging procedure to extras will apply. The SIG Guide https://wiki.centos.org/SIGGuide should have all the needed details for this (if not, complain to bstinson). It is highly recommended to actually test your new centos-release-* package from buildlogs before you ask that package to be signed and pushed to extras. The holiday season is fast approaching so (I) don't expect much activity regarding these changes in the following days. I'm hoping that the SIGs would take a look at this in early 2019, though. Thanks to those SIGs who have already made these changes to their centos-release-* packages! If you have questions, feel free to ask either here or on #centos-devel. Thanks for your time!

SCL packages in CentOS 7 that are expired and EOL
by Trevor Hemsley 30 May '19

30 May '19

Hi all I just had a glance at the various repos installed by centos-release-scl on CentOS 7 and a large number of the packages available in the CentOS version of this repo are both old and out of date and more importantly, EOL. They should be removed from our repos ASAP. I know we had/have a policy of cleaning these repos up at point release times but it's quite apparent that we have missed all of these for a number of point releases from 7.3 onwards. Thus I propose we make an exception for these and remove them anyway, regardless of point release time or not. A lot of them should have been gone for 3 years already. The following are all dead as per https://access.redhat.com/support/policy/updates/rhscl - some of them deader than others. devtoolset-3 - Oct 2016 devtoolset-4 - Nov 2017 devtoolset-6 - Nov 2018 git19 - Oct 2016 mariadb-5.5 - Oct 2016 maven30 - Oct 2016 mogodb24 - Oct 2016 mysql55 - Oct 2016 nginx16 - Oct 2016 nodejs010 - Oct 2016 perl516 - Oct 2016 php54 - Oct 2016 php55 - Oct 2016 postgresql92 - Oct 2016 python33 - Oct 2016 rh-git29 - Nov 2018 rh-mariadb100 - Apr 2018 rh-mongodb26 - Apr 2018 rh-mongodb30upg - Apr 2018 rh-mysql56 - Apr 2018 rh-nginx18 - Nov 2018 rh-nodejs4 - May 2018 rh-passenger40 - Apr 2018 rh-perl520 - Apr 2018 rh-postgresql94 - Apr 2018 rh-python34 - Apr 2018 rh-ror41 - Apr 2018 rh-ruby22 - Apr 2018 rh-thermostat16 - Oct 2016 rh-varnish4 - Nov 2018 ror40 - Oct 2016 ruby193 - Oct 2016 ruby200 - Oct 2016 rust-toolset-7 - ??? sclo-python34 - Apr 2018 thermostat1 - Oct 2016 v8314 - Apr 2018 The following go EOL this month: ==================== rh-mariadb101 - May 2019 rh-maven33 - May 2019 rh-mongodb32 - May 2019 rh-nodejs6 - May 2019 rh-postgresql95 - May 2019 rh-python35 - May 2019 rh-ror42 - May 2019 rh-ruby23 - May 2019 sclo-python35 - May 2019 sclo-ror42 - May 2019 These are not mentioned on the above page but could be part of other SCLs that are still current (maybe!) rh-eclipse46* sclo-cassandra3 - ???? sclo-git212 - ??? sclo-git25 - ??? go-toolset - no expiration date given libasan[2,3,4,5] libcilkrts, liblsan, libmpx, libtsan, libubsab[1] - ???? llvm-toolset-7 - part of devtoolset-7? sclo-subversion19 - ??? sclo-vagrant1 - ???

CRI-O rpm not published to public repo hence not signed
by Daniel Comnea 28 May '19

28 May '19

Hi Lokesh, If i'm not mistaken i guess you are still building/ maintaining the CRI-O rpms ? If so could you please let me know where is the CI job which builds the rpms [1] which are tagged into [2] ? The reason i'm bringing this up is because folks in K8s community are using the cri-o rpms published to [3] and that should have never happened. Now with Fabian (@arrfab) help we manage to track down that there was no request being made by you(or the SIG chair under which the cri-o falls into) to sign and publish the rpm to mirror.centos.org and that backs the issue folks raised [3]. As a solution, i can suggest one (if you are willing to accept it): 1. you follow the process and 1. tag and promote the rpms from -candidate to -testing and then to paas7-crio-114-release 2. create a ticket on bugs.c.o so our Infra folks can sign and publish the rpm which i guess will end up in [4] 2. or we can try to get it under PaaS SIG and then publish it under [5] Once all that is done then i'm happy to even announce on K8s/ CRI mailer as projects like kubespray are using it/ consuming the rpm. Cheers, Dani [1] https://cbs.centos.org/koji/buildinfo?buildID=25889 [2] https://cbs.centos.org/koji/taginfo?tagID=1704 [3] https://github.com/kubernetes-sigs/kubespray/pull/4781#issuecomment-4938274… [4] http://mirror.centos.org/centos/7/os/x86_64/Packages/ [5] http://mirror.centos.org/centos/7/paas/x86_64/

snmp walk not working in FIPS compliant algorithms
by Maheshwari, Shagun 24 May '19

24 May '19

Hi, When we attempt to do SNMP walk v3 in CentOS7 when its FIPS enabled, we get the below error: aes_misc.c(74): OpenSSL internal error, assertion failed: Low level API call to cipher AES forbidden in FIPS mode! FIPS support SHA and AES. This error is coming internally and it needs changes from rpm level. When we try the same scenario in RHEL 6 servers, we don't get this error and we get output successfully. The SNMP rpm we use is net-snmp-5.7.2-28.el7.x86_64 Please let us know how we can resolve this error? Any patch is available for this or not. Regards, Shagun

Hi, yesterday I built adn released qemu-kvm-ev with fixes for Microarchitectural Store Buffer Data CVE. The build landed correctly on x86_64 at http://mirror.centos.org/centos/7/virt/x86_64/kvm-common/?C=M;O=D but it's still missing on ppc64le at http://mirror.centos.org/altarch/7/virt/ppc64le/kvm-common/?C=M;O=D and on aarch64 at http://mirror.centos.org/altarch/7/virt/aarch64/kvm-common/?C=M;O=D the build is https://cbs.centos.org/koji/buildinfo?buildID=26025 and the mappings looks correct: https://git.centos.org/centos/cbs-content-control/blob/master/f/sign_list.p… https://git.centos.org/centos/cbs-content-control/blob/master/f/sign_list.a… Since this is an important CVE fix, can you please prioritize work on this issue?

CentOS 8.0.1905 build status
by Fabian Arrotin 14 May '19

14 May '19

Hi, As everybody is probably aware now, RHEL 8.0 was released earlier this week . Instead of publishing multiple blog posts here and then point to updated content, we decided this time to have a dedicated wiki page that can be used to track our current status : https://wiki.centos.org/About/Building_8 So now you can look at that page while we're busy on those tasks, and refresh from time to time. Let's spread the news about the wiki page and point people (on mailing-lists, irc, forums, etc) to that page to get all latest news about CentOS 8.0.1905 build status ! Cheers ! -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 56BEC54E | twitter: @arrfab

Preliminary RHEL 8 review
by Nico Kadel-Garcia 14 May '19

14 May '19

I've noticed a few things that may help other people setting up test environments. 1) The RPMs on the installation media are split into two distinct repositories, "BaseOS" and "AppStream", for no reason I can discern. This means that if you try, like me, to mount a DVD image and use it as local yum repo for testing out kickstart setups and mock builds, you need to address the multiple necessary repositories with the new names. 2) For Virtualbox, it absolutely needs more than 1 GB of RAM.With only 1 GB, it hands during hte firstboot setups. 3) Mock is going to be.... awkward to port, due to multiple python dependencies in on the DVD.

Hi Pablo, Sorry for the late reply and thank you for pushing us for getting the serial port repaired, the port was not functioning. Now that we have it working, I have started to debug through the serial communication, but I want to raise some doubts in the process. In the blog, https://wiki.centos.org/SpecialInterestGroup/AltArch/armhfp, the last step is to *dd* the *u-boot-with-spl.bin* file as follows, > dd if=/usr/share/uboot/${boardmodel}/u-boot-sunxi-with-spl.bin of=${sdcard} bs=1024 seek=8 conv=fsync,notrunc > > But is missing how to load the *u-boot-spl.bin *and* u-boot.img. *Could you please shine some light on this for us? I understand that the order has to be ROM code -> SPL -> u-boot -> kernel. Does it means that I have to also dd u-boot.img, like here, > dd if=u-boot-spl.bin of=/dev/sdX bs=1024 seek=8 > dd if=u-boot.img of=/dev/sdX bs=1024 seek=*X (?)* > > On the other hand, I also tried to boot with another method using only the centOS Rootfs file (in the root ext4 partition), and the Boot.bin and image.ub files (in boot partitions) which I created using petalinux/yocto. The kernel boots up but falls into the kernel panic, with errors as *cant execute the /sbin/init - (error -8)* -> which refers as permission denied. Please let us know what you think of this too!

Installing kernel 4.14.34 through kickstart
by Far Had 06 May '19

06 May '19

Hi, Trying to compile and put kernel 4.14.34 into the CentOS 7 (1511 release) DVD with a ks.cfg already configured. This ks DVD has been working fine with the original 3.10 kernel. Here is what I did: I built rpm packages of the 4.14.34 kernel with disabled kernel debugging option. This gave me 3 rpm files: kernel, kernel-header and kernel devel. I replaced them with their equivalents in isolinux/packages directory in the DVD ISO image and made a new ISO file out of it. when booting from this image, automatic installation fails after installing all packages in the post installation at "generating initramfs" phase. The exact error text is: "No such file or directory" (image attached) Regards.

IRC Meeting Changes
by John R. Dennison 01 May '19

01 May '19

For the past few years the CentOS Project has been holding IRC meetings for our various Special Interest Groups (SIGs) and other projects in the #centos-devel channel on the freenode IRC network. This has, for the most part, worked out fairly well. However, as this is a shared channel, at times things can become a bit hectic and confusing as people occasionally interrupt a meeting in progress. Not only does this break the flow of the meeting but it also injects noise into the logs that the project maintains for historical reference. This policy was also different from most other projects which have a dedicated "meetings" channel to be used for these purposes. In order to address the issue the project has made the decision to transition meetings to the #centos-meeting channel. This is a dedicated channel to be used solely for meetings. We feel this will help alleviate any potential issues with interruptions and other distractions. This channel is managed by the same group of people, our IRC Ops Team, as is #centos-devel and our channel bots are present to help as necessary. An additional bonus of this transition will be that the meeting bot (centbot) responsible for meeting oversight and logging will now be able to set the channel topic to reflect meeting status. This was not previously possible due to policy as we did not want to have the bot op'd unless absolutely necessary in a shared channel. We are planning this transition for June 1st in order to give the stakeholders involved ample time to alert their communities of the change and to ensure we have made the necessary changes on our end to ensure a smooth transition for people who access the logs via the https://www.centos.org/minutes/ interface. Any questions regarding this transition should be addressed either via the centos-devel mailing list or on the #centos-devel IRC channel on freenode. Additionally people can reach out to me personally on IRC (Bahhumbug on freenode) or via email if they have questions or concerns regarding this or other CentOS IRC matters. Thanks and see you in #centos-meeting :) -- The most valuable thing you can make is a mistake - you can't learn anything from being perfect. -- Adam Osborne (1939-2003), American entrepreneur
