system call msgrcv() freom 32-bit application shows error: msgrcv: No message of desired type
by Gabriella Schmidt 25 Apr '14

25 Apr '14

The latest RHEL7 still shows the error msgrcv: No message of desired type if msgrcv() is called with negative arguments within 32-bit applications. It is in Red Hat Bugzilla – Bug 1042807 but as we dont have RHN Support anymore we cant take a ticket there. I have tested the kernel-lt-3.10.37-1.el6.elrepo.x86_64 and kernel-ml-3.14.1-1.el6.elrepo.x86_64 on CentOS-6 and the 3.10.37 still show the problem, while its fixed in 3.14 The fix is very small ( see attachment ), but I dont know what is the best way to get it fixed in the 3.10 kernels too. -- Kind Regards Gabriella Schmidt -- NMR Software -- Bruker BioSpin GmbH

ostree as a delivery model
by Karanbir Singh 23 Apr '14

23 Apr '14

The Fedora cloud sig has been talking about using the gnome ostre to deliver a potential platform, i think this is fantastic and leads in quite nicely to the conversations we've all been having about a minimial manageable image ( either for virt or cloud usage, or even baremetal ). I wonder if we can make this work for CentOS-6 now and 7 when its around ? the rpm-ostree stack seems to have a systemd dep though. Who fancies taking a dig at it ? references: ostree: https://wiki.gnome.org/action/show/Projects/OSTree rpm-ostree: https://github.com/cgwalters/rpm-ostree ( this is what one would use to take a bunch of rpms and make them into an ostree VM, it spits out a qcow2 image ) -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

snd_hda_intel module tweaking
by Chris Pemberton 22 Apr '14

22 Apr '14

Long story short... I'm recompiling the snd_hda_intel module to enable CONFIG_SND_HDA_RECONFIG. This will allow me to reset the pins on the card to get my sound working. (This option is already set in arch and ubuntu - where I can reprogram my pins and get sound working). I followed the 2 CentOS wikis pertaining to getting the full kernel sources and compiling a module... all seemed to go perfect. Unfortunately, when I try to load the new snd_hda_intel.ko module, I get the following: FATAL: Error inserting snd_hda_intel (/lib/modules/2.6.32-431.11.2.el6.x86_64/extra/snd-hda-intel.ko): Invalid module format A little googling suggested I run 'file' on the two modules and here is the output: /lib/modules/2.6.32-431.11.2.el6.x86_64/extra/snd-hda-intel.ko: ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not stripped /lib/modules/2.6.32-431.11.2.el6.x86_64/kernel/sound/pci/hda/snd-hda-intel.ko: ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not stripped They seem identical? Any suggestions where I could go from here? I'm currently recompiling the entire kernel and will just copy over the new modules and see if something better happens. Thanks, Chris

Issue with 32-bit build of devtoolset 1.1?
by Dave Johansen 14 Apr '14

14 Apr '14

I'm trying to build ODB on RHEL 5 32-bit and I get some linker errors. Here are some examples: odb-option-functions.o: In function `__exchange_and_add': /opt/rh/devtoolset-1.1/root/usr/lib/gcc/i386-CentOS-linux/4.7.2/../../../../include/c++/4.7.2/ext/atomicity.h:48: undefined reference to `__atomic_fetch_add_4' odb-profile.o: In function `__exchange_and_add': /opt/rh/devtoolset-1.1/root/usr/lib/gcc/i386-CentOS-linux/4.7.2/../../../../include/c++/4.7.2/ext/atomicity.h:48: undefined reference to `__atomic_fetch_add_4' semantics/relational/odb-name.o: In function `__exchange_and_add': /opt/rh/devtoolset-1.1/root/usr/lib/gcc/i386-CentOS-linux/4.7.2/../../../../include/c++/4.7.2/ext/atomicity.h:48: undefined reference to `__atomic_fetch_add_4' odb-options.o:/opt/rh/devtoolset-1.1/root/usr/lib/gcc/i386-CentOS-linux/4.7.2/../../../../include/c++/4.7.2/ext/atomicity.h:48: more undefined references to `__atomic_fetch_add_4' follow It builds fine on RHEL 5 64-bit. Any ideas what the issue might be? Thanks, Dave

centos variant ?
by Glen Gardner 14 Apr '14

14 Apr '14

Some time ago, I created a simple cluster configuration kit based on CENTOS. http://gridtoys.com/pvc/pvc.html The configuration kit is based on the use of a centos kickstart DVD and a simple shell script. Now I am reading some rather fuzzy definitions for CENTOS variants and am wondering if what I am doing with the cluster configuration kit is better suited as a CENTOS variant , or if it really fits the proposed definition of a variant at all? Thanks Glen

updating the official Docker image for CentOS
by Karanbir Singh 13 Apr '14

13 Apr '14

hi The Docker folks host an image for CentOS Linux 6 here : https://index.docker.io/_/centos/ - looking to upgrade this image, and to take ownership of that account ( for the CCIS ) I've built an image, which is in line with the existing image they host, but has been updated to include content released via mirror.centos.org to today. http://cloud.centos.org/centos/6/devel/CentOS-6-20140411-x86_64-docker_01.i… is the image please test worth noting that this is represented as CentOS-6, dropping the point release and replacing it with a date - means we can update it more frequently than only at every point release time ( and we set user expectation around that ). We can, if there is a need, still push images that are in line with a point release snapshot. Unless there is reason not to, Jim and I will start working towards replacing that docker official centos image with his one in the next 24 hrs. regards -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

Storage SIG Infrastructure Discussion
by Patrick McGarry 11 Apr '14

11 Apr '14

Hey all, Just wanted to keep people up on the latest discussions surrounding how we are planning to do the first pass of the Storage SIG repo setup. This is obviously still a pretty rough sketch as the CentOS infrastructure evolves to handle this use case, so if people have strong feelings please weigh in! Our current plan is to start with a development repository for the Storage SIG where we can initially import our packages. Once they are deemed "production" (still working on the mechanics of how/when to graduate) we will push them over to centos-extras. Centos-extras will be our "production" repository for now and will be a hard dependency for our devel repo so that when packages move no one gets orphaned. The execution of this is to start pushing src rpms to git.centos.org and github with the expectation that by the end of Apr or early May there will be a mirror in place between those two locations. Once the mirror is set up the hope is to use automatic triggers with Koji to trigger builds as new bits are pushed to the mirror. KB is working on docs for: 1) how to get builds going 2) how to join/administer the git repositories. Once those are in place we'll continue to tweak things until we have a smooth working model. I welcome any input or thoughts folks might have, especially from veteran rpm builders. Thanks!

Virt SIG moving forward
by Lars Kurth 11 Apr '14

11 Apr '14

Hi, just a quick note that I found the CentOS board meeting minutes which state that the Virt SIG is moving forward. Consequently I updated * http://wiki.centos.org/SpecialInterestGroup/Virtualization * http://wiki.centos.org/SpecialInterestGroup/Virtualization/Proposal (& http://www.centos.org/minutes/2014/march/centos-devel.2014-03-05-21.04.html) Apologies for the short notice. We are going to have a first quick meeting on Friday the 11th, 11:00AM BST (London time) because many of us will be on the road the following weeks and we didn't want to stall progress. Please drop me a line if you want to participate on lars dot kurth at xenproject dot org. If you cannot make it, don't worry: we will set up a proper regular meeting once everyone is back from their travels and revisit agenda items as needed. It probably wont be very popular, but I'd propose a hangout or teleconf and will write up minutes. I expect that we will cover * Meeting time & cadence * Form & Function (confirm who does what based on the current list of members) * Infrastructure loose ends (repositories, lists, access, etc - enough pointers to get started) * Establish a draft TODO list * Identify potential additions to SIG (KVM, OpenVZ, etc. and whether there are any individuals to proactively reach out to) * AOB Best Regards Lars
