Btrfs Authenticated File-System Support Looks To Be Revived

Filed under

Last year a SUSE developer sent out a set of patches adding authentication support to the Btrfs file-system. Btrfs already has checksums on meta-data blocks and data blocks while the original implementation of these authentication patches was performing HMAC on a SHA256 checksum as a keyed hash. A proper key in turn is then needed to mount a verified file-system.

That Btrfs authentication support wasn't picked up at the time and the SUSE engineer, Johannes Thumshirn, since left the company. But following new inquiries over the work, it sounds like it will be revived for this authentication that could be used for the likes of embedded devices and containers.

SUSE/OpenSUSE: SUSE Linux Enterprise 15 Service Pack 2, SUSE Manager 4.1 Public Beta and OpenSUSE Tumbleweed

Filed under
  • SUSE Linux Enterprise 15 Service Pack 2 Public Release Candidate 1!

    Since Public Release Candidate 1 is released more than 2 months after the release of the Public Beta, tons of fixes and enhancement is included in this milestone.

  • SUSE Manager 4.1 Public Beta 3!

    We are pretty excited to announce SUSE Manager 4.1 Public Beta 3. As usual, we have prepared tons of updates and we hope you will like it. We also now have a new Public Mailing List, so you can share your feedback with our Public Beta Community, our Engineering and our Product Managers.

  • openSUSE Tumbleweed – Review of the week 2020/17

    The last week was filled with success. The major change was surely the removal of python2-FOO modules from the distro. Not exactly all are gone yet (packages that fail to build do also not change the published modules), but we went form 2564 (Snapshot 0417) modules down to 203 (0422). But of course, that’s not all that has happened. After all, we released 6 snapshots in the last week (0415, 0416, 0417, 0419, 0421 and 0422).

  • SUSE Suggests openSUSE Community To Synchronize Code Streams

    In its proposal to the openSUSE community, SUSE has suggested bringing the code streams of both SUSE Linux Enterprise and openSUSE Leap closer together. The proposal includes SLE binaries for the community version.

    According to the proposal, bringing the code streams closer together to provide full compatibility provides several advantages to the community going forward. These include the use of higher-quality code due to the clean-up of spec-files, an improved relationship between the two distributions, easier bug reporting, less code streams to maintain, extensively tested packages and the inclusion of SLE supported architectures like s390x.

  • SUSE Stratos Console 3.0 & 3.1

    SUSE Stratos Console 3.0 was released a little over a month ago without the fanfare it absolutely deserves. Now the 3.1 release which will be part of Cloud Application Platform 2.0 has just been released, so let’s go over some of the great work the Stratos team has done over the last few months for both releases.

  • Managing Linux in the Cloud with SUSE Manager 4

    Cloud environments grow organically and often include a dizzying combination of virtual, bare metal and container-based systems. If cloud computing is part of your Linux landscape, you’ll save time and money with a single tool for managing all your Linux resources. SUSE® Manager 4 is a versatile Linux management tool built for the cloud.

  • VMware ESXi 6.7 + SUSE Enterprise Storage = Certified
  • Highlights of YaST Development Sprint 97

    Once most of the features that were planned for SUSE 15 SP2 and openSUSE 15.2 are ready, the team is shifting its focus to SP3 and 15.3. Of course, we are still polishing the releases around the corner, so in the summary of this sprint, you can find a mixture of bug fixes, small features, and preparation for the future work.

Servers: XenServer, OpenStack, Cartesi, SUSE and Red Hat

Red Hat
  • XCP-ng celebrates six-figure download milestone

    XCP-ng, the crowdfunded effort to deliver an open-source version of XenServer, has passed the 100,000-download mark.

    Founder Olivier Lambert has described the milestone as “only the beginning but it's a symbolic level, and it tells a lot about how many people have been convinced to use XCP-ng!”

    And not just people: in January 2020 the Xen Project adopted XCP-ng as an incubation project. Xena advisory board chair George Dunlap likened the decision to do so as akin to RedHat teaming up with CentOS – it may look like internal competition but having two projects with the same goal in proximity is mutually beneficial.

  • Interoperability of Open-source Tools: The Emergence of Interfaces

    Katie Gamanji works as a Cloud Platform Engineer at Condé Nast. Previously, she worked on maintaining and automating site delivery on OpenStack-based infrastructure, which transitioned into a role with a focus on designing, deploying and evolving a Kubernetes centric infrastructure.

  • Cartesi creates Linux infrastructure for blockchain DApps

    Cartesi is a DApp infrastructure.

    DApps (sometimes called Dapps) are from the blockchain universe and so, logically, the apps part stands for application (obviously) and the D part stands for decentralised (only obvious once you know that we’re talking distributed immutable language here).

    According to the guides section at blockgeeks, DApps are open source in terms of code base, incentivised (in terms of who validates it) and essentially decentralised so that all records of the application’s operation must be stored on a public and decentralised blockchain to avoid pitfalls of centralisation.

    So then, Cartesi is a DApp infrastructure that runs an operating system (OS) on top of blockchains.

  • SUSE’s Bridge Between Kubernetes & Cloud Foundry: Thomas Di Giacomo

    Why did SUSE contribute its project to Cloud Foundry? How is KubeCF going to further bring Kubernetes and Cloud Foundry together? We sat down with Thomas Di Giacomo, President of Engineering and Innovation at SUSE, to get answers to these questions.

  • ZTE collaborates with Red Hat to quickly deploy open 5G Networks

    The collaboration includes a new reference architecture aimed at enabling telcos to more effectively deploy virtual network functions (VNFs) on Red Hat openStack platform, Red Hat’s highly-scalable and agile Infrastructure-as-a-Service (IaaS) solution on ZTE’s hardware.
    The collaboration combines the open source innovation available in Red Hat openStack platform with ZTE’s Cloud Core Network components. It offers a replicable and cost-effective network solution that can speed integration time by 5 times based on internal Red Hat testing.

  • How Edge Is Different From Cloud – And Not

    As the dominant supplier of commercial-grade open source infrastructure software, Red Hat sets the pace and it is not a surprise that IBM was willing to shell out an incredible $34 billion to acquire the company. It is no surprise, then, that Red Hat has its eyes on the edge, that amorphous and potentially substantial collection of distributed computing systems that everyone is figuring out how to chase.

    To get a sense of what Red Hat thinks about the edge, we sat down with Joe Fernandes, vice president and general manager of core cloud platforms at what amounts to the future for IBM’s software business. Fernandes has been running Red Hat’s cloud business for nearly a decade, starting with CloudForms and moving through the evolution of OpenShift from a proprietary (but open source) platform to one that has become the main distribution of the Kubernetes cloud controller by enterprises. Meaning those who can’t or won’t roll their own open source software products.

Tumbleweed Snapshots this week bring Salt 3000, LLVM10, update of TigerVNC

Filed under

Since last Thursday, a total of five openSUSE Tumbleweed snapshots were released.

Each snapshot had about between five to 10 packages updated.

The most recent snapshot, 202000414 has a few libraries updated like libgit2 0.28.5, libva 2.7.0 and libva-gl 2.7.0. Several patches and five Common Vulnerabilities and Exposures security fixes were made to the high performance, multi-platform VNC client and serve tigervnc 1.10.1. Midnight Commander (mc) 4.8.24, which is a text-mode full-screen file manager and visual shell, provided new skins and added yabasic (Yet Another BASIC) syntax highlighting. A minor update to plymouth’s 0.9.5 version removed unused kernel-headers and module-init-tools build dependencies and the xfce4-settings 4.14.3 updated translations and modified the display to allow for the use of a proper fallback configuration on “apply” and “toggle off”. The xfwm4 4.14.1 package, which is the window manager for the Xfce environment, fixed hostnames that were not showing initially when running apps remotely and the update fixed a crash with the Graphics Library that involved high CPU usage without a monitor. The snapshot is currently trending stable at a rating of 93, according to the Tumbleweed snapshot reviewer.

A new major version of the Mozilla Firefox browser was released in snapshot 20200413. The new 75.0 version improves the behavior performance on Linux when clicking on the Address Bar and the Search Bar, which now matches other desktop platforms; a single click selects all without primary selection; a double click selects a word; and a triple click selects all with primary selection. Additionally, Firefox is now available in Flatpak and a CVE memory safety bug for Firefox 75 and Firefox ESR 68.7 were fixed. The btrfsprogs package jumped from version 5.4.1 to version 5.6 and supports new hash algorithms in the 5.5 Linux Kernel; the new version also supports LOGICAL_INO_V2 features in logical-resolve. The new option ‘-o’ helps advanced dedupe tools. The libostree 2020.3 library was update in Tumbleweed from it’s previous 2019.6 verion; nine months of updates bring several newer features and fixes like support for making the /sysroot mount pointread-only upon start, and the error-handling around GPG verification was overhauled. Text editor nano 4.9.2 fixed a crash after undoing an at the end of a leading whitespace. The snapshot is currently trending at a moderate 83 rating on the [Tumbleweed snapshot reviewer](

  • Reasons To Give OpenSUSE A Try

    Probably the most special thing about openSUSE is YaST2: The complete control center capable of configuring everything on a Linux system. It comes by default on SUSE & openSUSE distributions. YaST2 is awesome because it contains a lot of options and functionalities.

  • SUSECON Digital – Everything You Hoped For (Except the Guinness)

    For nearly a decade, I have been very fortunate to lead the SUSECON team at SUSE. We have enjoyed double-digit attendance growth every year, and along the way we have made both fans and lifelong friends. Everyone who attends SUSECON comes away with great memories. When asked what the best things about the event were, they reply, “outstanding technical content, open access to subject matter experts, and a true feeling of community.”

    A few weeks ago, for reasons we all know too well, we were presented with a challenge: create an on-line experience that will deliver outstanding technical content, allow for open access to the people who create that content, and still maintain a feeling of community. Since that time, we have been hard at work to create a virtual SUSECON experience that will be as memorable as our live event.

  • Jitsi instance on

    In the times of Covid-19 and the people staying at home it is an adventure to get the tools to work from home without missing the benefits of face-to-face meetings.

    There are a lot of solutions out in the wild. But one promising solution is Jitsi. Until now we used the instances provided by other people.

    But now we are able to introduce:

    Our own Jitsi instance

    It is based on openSUSE Leap 15.1 and uses docker containers to deploy Jitsi. The current security warnings were also considered, furthermore the setup uses secure LDAP and HTTPS.

With coronavirus forcing us to work from home, SUSE suggests the Linux desktop

Filed under

None of the major enterprise Linux companies have been pushing the Linux desktop forward for some time. Their focus for over a decade now has been first on servers, then the cloud, and now, containers and Kubernetes. The Linux desktop has been on the backburner. Even Canonical with its Ubuntu desktop -- perhaps the first name in business Linux desktops these days -- is answering Linux desktop demand and not actually out there marketing it to customers.

The Linux desktop today is driven largely by developers and fans. The most popular Linux desktops, such as MX Linux, Manjaro, and (my own favorite) Linux Mint are community rather than corporate-driven.

But then along came the coronavirus and the sudden rush of people to work from home, and SUSE quickly figured out there was a new, underserved market for the Linux desktop: Companies with little in the way of resources that need to keep their businesses running with what their IT department and users already have at hand.

  • openSUSE Tumbleweed Is Now Available on AWS Marketplace

    openSUSE developer Alessandro de Oliveira Faria announced the availability of the openSUSE Tumbleweed operating system on the AWS Marketplace.

    openSUSE, as a GNU/Linux distribution, was already available on the AWS (Amazon Web Services) Marketplace, but as the stable openSUSE Leap release.

    As you probably know already, openSUSE also offers a rolling-release version of its operating system, called openSUSE Tumbleweed.

    And the good news is that, as of this month, you can now install openSUSE Tumbleweed as a Linux server on Amazon AWS, and it’s intended for everyone wants to use the latest openSUSE release.

  • openSUSE Tumbleweed available on AWS

    I make openSUSE Tumbleweed available on AWS. The Tumbleweed distribution is a pure rolling release version of openSUSE containing the latest stable versions of all software instead of relying on rigid periodic release cycles. The project does this for users that want the newest stable software.

    Tumbleweed is based on Factory, openSUSE’s main development codebase. Tumbleweed is updated once Factory’s bleeding edge software has been integrated, stabilized and tested. Tumbleweed contains the latest stable applications and is ready and reliable for daily use.
