Announcing the PostgreSQL STIG

Friday 31st of March 2017 11:21:22 PM
Crunchy Data has announced the availability of a "security technical implementation guide" for the PostgreSQL database management system. "While the STIG was authored for the benefit of the U.S. Government, the DISA PostgreSQL STIG offers security-conscious enterprises a comprehensive guide for the configuration and operation of open source PostgreSQL. Enterprises can refer to the STIG as for guidance on PostgreSQL security best practices they consider open source PostgreSQL as an alternative to proprietary, closed source, database software."

Scientific Linux 5 End of Life

Friday 31st of March 2017 11:04:29 PM
The Scientific Linux project has announced that Scientific Linux 5 has reached its end of life. "After March 31 2017 Scientific Linux 5 will not receive further updates and the files will be archived. The existing files will be moved into for archival purposes after March 31 2017. This will break existing yum repos and kickstarts using the official distribution servers."

[$] Extending statx()

Friday 31st of March 2017 09:32:36 PM

When Andreas Dilger proposed the statx() topic for the 2017 Linux Storage, Filesystem, and Memory-Management Summit, the system call had still not been merged. But that all changed in the 4.11 development cycle when Al Viro merged the system call to provide additional file information. So, unlike previous years, the discussion was not about how to merge such a system call but, instead, how to extend statx() for additional file information.

New stable kernels released

Friday 31st of March 2017 03:08:43 PM
The 4.10.8, 4.9.20, and 4.4.59 stable kernels have been released. Users of those kernel series should upgrade.

[Update: It appears that the urgency for getting these stable kernels out comes from a fix for CVE-2017-7184, which is a local privilege-escalation vulnerability.]

This release adds a new transform tool, better zooming, better title editing, and more; the razor tool has also made a comeback.

LibrePlanet session videos released

Thursday 30th of March 2017 10:50:26 PM
Videos from the LibrePlanet 2017 keynotes and sessions are becoming available at; many are already posted and others will be filled in over the next few days. "LibrePlanet 2017 closed Sunday, March 26th with a keynote by Sumana Harihareswara, bringing to an end two days of presentations, workshops, hacking, conversations, and fun. More than 400 people interested in free software joined the Free Software Foundation (FSF) and MIT's Student Information Processing Board (SIPB) in Cambridge, MA for the 9th annual LibrePlanet." LWN was there for the conference, so you can expect more coverage coming soon (our first article on Conor Schaefer's SecureDrop talk appeared in the March 30 weekly edition).

[$] Overlayfs features

Wednesday 29th of March 2017 05:24:41 PM
The overlayfs filesystem is being used more and more these days, especially in conjunction with containers. Amir Goldstein and Miklos Szeredi led a discussion about recent and upcoming features for the filesystem at LSFMM 2017.

[$] Memory-management patch review

Wednesday 29th of March 2017 03:21:04 PM
Memory-management (MM) patches are notoriously difficult to get merged into the mainline kernel. They are subjected to a high degree of review because this is an area where it is easy to get things wrong. Or, at least, that is how it used to be. The final memory-management session at the 2017 Linux Storage, Filesystem, and Memory-Management Summit was concerned with patch review in the MM subsystem — or the lack of it.

Security updates for Wednesday

Wednesday 29th of March 2017 03:10:47 PM
Security updates have been issued by CentOS (icoutils and openjpeg), Debian (eject, graphicsmagick, libytnef, and tnef), Fedora (drupal8, firefox, kernel, ntp, qbittorrent, texlive, and webkitgtk4), Oracle (bash, coreutils, glibc, gnutls, kernel, libguestfs, ocaml, openssh, qemu-kvm, quagga, samba, samba4, tigervnc, and wireshark), Red Hat (curl), Slackware (mariadb), SUSE (samba), and Ubuntu (apparmor).

GCC for new contributors

Wednesday 29th of March 2017 01:38:42 PM
David Malcolm has put together the beginnings of an unofficial guide to GCC for developers who are getting started with the compiler. "I’m a relative newcomer to GCC, so I thought it was worth documenting some of the hurdles I ran into when I started working on GCC, to try to make it easier for others to start hacking on GCC. Hence this guide."

[$] The next steps for userfaultfd()

Wednesday 29th of March 2017 01:24:09 PM
The userfaultfd() system call allows user space to intervene in the handling of page faults. As Andrea Arcangeli and Mike Rapaport described in a 2017 Linux Storage, Filesystem, and Memory-Management Summit session dedicated to the subject, userfaultfd() was originally created to help with the live migration of virtual machines between physical hosts. It allows pages to be copied to the new host on demand, after the machine itself has been moved, leading to faster, more predictable migrations. Work on userfaultfd() is not finished, though; there are a number of other features that developers would like to add.

[$] Supporting shared TLB contexts

Tuesday 28th of March 2017 07:57:14 PM
A processor's translation lookaside buffer (TLB) caches the mappings from virtual to physical addresses. Looking up virtual addresses is expensive, so good performance often depends on making the best use of the TLB. In the memory-management track of the 2017 Linux Storage, Filesystem, and Memory-Management Summit, Mike Kravetz described a SPARC processor feature that can improve TLB performance and explored ways in which that feature could be supported.

Kubernetes 1.6 released

Tuesday 28th of March 2017 07:53:42 PM
Version 1.6 of the Kubernetes orchestration system is available. "In this release the community’s focus is on scale and automation, to help you deploy multiple workloads to multiple users on a cluster. We are announcing that 5,000 node clusters are supported. We moved dynamic storage provisioning to stable. Role-based access control (RBAC), kubefed, kubeadm, and several scheduling features are moving to beta. We have also added intelligent defaults throughout to enable greater automation out of the box."

Google's new open-source site

Tuesday 28th of March 2017 06:17:37 PM
Google has announced the launch of "Today, we’re launching, a new website for Google Open Source that ties together all of our initiatives with information on how we use, release, and support open source. This new site showcases the breadth and depth of our love for open source. It will contain the expected things: our programs, organizations we support, and a comprehensive list of open source projects we've released. But it also contains something unexpected: a look under the hood at how we "do" open source."

[$] Huge pages in the ext4 filesystem

Tuesday 28th of March 2017 03:38:48 PM
When the transparent huge page feature was added to the kernel, it only supported anonymous (non-file-backed) memory. In 2016, support for huge pages in the page cache was added, but only the tmpfs filesystem was supported. There is interest in expanding support to other filesystems, since, for some workloads, the performance improvement can be significant. Kirill Shutemov led the only session that combined just the filesystem and memory-management tracks at the 2017 Linux Storage, Filesystem, and Memory-Management Summit in a discussion of adding huge-page support to the ext4 filesystem.

Ubuntu Phone security updates end in June, app store closing

When Mark Shuttleworth, founder of Canonical (the company behind the Ubuntu Linux distribution), announced his company would not only be abandoning their custom desktop environment (Unity), but also halting development on their phone/tablet operating system, many questions were left unanswered. One of those questions: What happens to the existing phones and tablets running Ubuntu Touch that have already been sold? Read more

  • 3 signs your Kubernetes distro is built to last
    It's hard to turn around these days without bumping into a Kubernetes distribution. For example, Mirantis recently buffed its OpenStack distribution to use Kubernetes as an internal component and for container management. Major Linux server distributions include it now. For Kubernetes adopters, it's all good news. It means the most remarkable development in the container world since, well, containers themselves is enjoying strong uptake and acceptance.
