__gthrw___pthread_key_create in devtoolset-6
by dacav 01 Jun '18

01 Jun '18

Hello good people I'm packaging for CentOS 7 a piece of proprietary software. The software is written in C++14, so I need to use the devtoolset to run it. Unfortunately I'm having some issues with linking of pthreads. First off I'm getting this warning: In file included from /opt/rh/devtoolset-6/root/usr/include/c++/6.3.1/x86_64-redhat-linux/bits/gthr.h:148:0, from /opt/rh/devtoolset-6/root/usr/include/c++/6.3.1/ext/atomicity.h:35, from /opt/rh/devtoolset-6/root/usr/include/c++/6.3.1/bits/ios_base.h:39, from /opt/rh/devtoolset-6/root/usr/include/c++/6.3.1/ios:42, from /opt/rh/devtoolset-6/root/usr/include/c++/6.3.1/ostream:38, from /opt/rh/devtoolset-6/root/usr/include/c++/6.3.1/iostream:39, from src/logd-main.cpp:23: /opt/rh/devtoolset-6/root/usr/include/c++/6.3.1/x86_64-redhat-linux/bits/gthr-default.h:236:10: warning: 'int __gthrw___pthread_key_create(pthread_key_t*, void (*)(void*)) throw ()' used but never defined __gthrw2(__gthrw_(__pthread_key_create), …Where the problematic line is a `#include <iostream>`. Then of course it gets problematic upon linking time objs/intel-debug/src/logd-main.o:(.rodata+0x8): undefined reference to `__gthrw___pthread_key_create(unsigned int*, void (*)(void*))' collect2: error: ld returned 1 exit status I searched around on the Web: the classic suggestion (from stackoverflow and such) will be to check for the `-pthread` flag to be present at compilation. This is of course tackled already. Since the compilation is working in other contexts, I started to wonder if this is some known problem in CentOS + Devtoolset: did someone have similar issues? Perhaps there's something wrong in how I do the build. Is there in CentOS some software which is using Devtoolset which I could take as example for my build? Thanks in advance for any suggestion :)

CentOS community newsletter - Call for content
by Rich Bowen 29 May '18

29 May '18

As part of our community outreach effort, we are rebooting the 'CentOS Pulse' newsletter, which was discontinued about 8 years ago. The purpose of this newsletter is to provide a high-level update on what CentOS is up to, to the peripheral audience - including the tech press - who are less connected with the daily life of the project. If your SIG would like to provide an update, or if you have something else you'd like to share with this audience, please do so here: https://wiki.centos.org/Newsletter/1801 , where I am drafting the newsletter. Or email me directly with what you'd like to put in there. We are targeting Tuesday, June 5th (generally, the first Tuesday of each month) for publication, so you have a few weeks. For historical context, you can read back-issues at https://wiki.centos.org/Newsletter/ to see what these used to look like. -- Rich Bowen - rbowen(a)redhat.com @CentOSProject // @rbowen 859 351 9166

[Infra] - planned outage : {bugs, fr, status}.centos.org
by Fabian Arrotin 24 May '18

24 May '18

Due to a hardware replacement, we'll have to power down the hypervisor hosting several VMs, including the ones used for the following impacted services : * https://bugs.centops.org * https://status.centos.org * https://fr.centos.org Hardware maintenance is scheduled for """"Thursay May 24th, 12:00 pm UTC time"""". You can convert to local time with $(date -d '2018-05-24 12:00 UTC') Root cause : a HDD in the array used to host the VMs failed, and there is no hot-swap capabilities, so full "power off" is required to replace the failed HDD and then start the rebuild operation. That means that those services (already impacted) will be slower during the rebuild operation, but at least reachable Thanks for your comprehending and patience. on behalf of the Infra team, -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 56BEC54E | twitter: @arrfab

CentOS Atomic Host 7.1804 Available for Download
by Jason Brooks 23 May '18

23 May '18

The CentOS Atomic SIG has released an updated version (https://wiki.centos.org/SpecialInterestGroup/Atomic/Download) of CentOS Atomic Host (7.1804), a lean operating system designed to run Linux containers, built from standard CentOS 7 RPMs, and tracking the component versions included in Red Hat Enterprise Linux Atomic Host. This release, which is based on the RHEL 7.5 source code, now ships without any baked-in Kubernetes rpms, which makes it simpler for users to layer their preferred Kubernetes or OpenShift packages onto the host. CentOS Atomic Host includes these core component versions: atomic-1.22.1-3.git2fd0860.el7.x86_64 cloud-init-0.7.9-24.el7.centos.x86_64 docker-1.13.1-63.git94f4240.el7.centos.x86_64 etcd-3.2.18-1.el7.x86_64 flannel-0.7.1-3.el7.x86_64 kernel-3.10.0-862.2.3.el7.x86_64 ostree-2018.1-4.el7.x86_64 rpm-ostree-client-2018.1-1.atomic.el7.x86_64 Download CentOS Atomic Host CentOS Atomic Host is available as a VirtualBox or libvirt-formatted Vagrant box, or as an installable ISO, qcow2 or Amazon Machine image. For links to media, see the CentOS wiki (https://wiki.centos.org/SpecialInterestGroup/Atomic/Download) Upgrading If you’re running a previous version of CentOS Atomic Host, you can upgrade to the current image by running the following command: # atomic host upgrade Release Cycle The CentOS Atomic Host image follows the upstream Red Hat Enterprise Linux Atomic Host cadence. After sources are released, they’re rebuilt and included in new images. After the images are tested by the SIG and deemed ready, we announce them. Getting Involved CentOS Atomic Host is produced by the CentOS Atomic SIG (http://wiki.centos.org/SpecialInterestGroup/Atomic) based on upstream work from Project Atomic. If you’d like to work on testing images, help with packaging, documentation – join us! You’ll often find us in #atomic and/or #centos-devel if you have questions. You can also join the atomic-develmailing list if you’d like to discuss the direction of Project Atomic, its components, or have other questions. Getting Help If you run into any problems with the images or components, feel free to ask on the centos-devel mailing list. Have questions about using Atomic? See the atomic mailing list or find us in the #atomic channel on Freenode.

Issue with selinux load_policy command
by Veetil, Vyshnav 23 May '18

23 May '18

Hi, We have done changes in our Centos7.4 to disable unconfined user from our code. We have created an iso in which we have replaced unconfined with sysadm and we are performing an upgrade using the new iso. After upgrade current partition stop working . It started expecting policies for unconfined. When we perform a reboot things started working fine again. We are suspecting some issues with this command "load_policy -qi" When this command is being executed on partB in permissive mode and after we move system to enforcing mode. It start giving denials for unconfined. Can you explain what exactly load_policy do? Does it load the policies for all the partitions of the system ? Thanks and Regards, Vyshnav
