Systemd change has Linux users up in arms

Filed under
Red Hat

A change in the most recent version of systemd, the init system that has been recently adopted by many GNU/Linux distributions, has users up in arms.

The change, announced a few days ago, kills background processes by default when a user logs out, the opposite of the behaviour that was exhibited earlier.

This would cause problems for users, for example, of terminal multiplexers like screen and tmux as they would be unable to return to a process once they have logged out.

If a server admin had a bunch of scripts that logged into a server, then started a process using screen and logged out, the process would be killed. This is a fairly common thing that many admins do.

Pravin Satpute: How do you Fedora?

Filed under
Red Hat

Pravin Satpute started using Linux in 2004 when he was working with Dr. Nagarjuna Gadiraju of the Free Software Foundation of India. He was working on a project to develop libre fonts for Indian languages. At that time, he was using Knoppix with the KDE desktop. In 2006, he became interested in Fedora and starting using Red Hat Enterprise Linux (RHEL) in 2007 when he was given a laptop with RHEL 5. Quickly after receiving the laptop, he switched to Fedora 8. His childhood heroes were Steve Jobs, Ratan Tata and Sachin Tendulkar. His favorite movies are Inception and The Mummy.

  • Why SELinux is inherently complex

    The root of SELinux's problems is that SELinux is a complex security mechanism that is hard to get right. Unfortunately this complexity is not (just) simply an implementation artifact of the current SELinux code; instead, it's inherent in what SELinux is trying to do.

  • SELinux is beyond saving at this point

    SELinux has problems. It has a complexity problem (in that it is quite complex), it has technical problems with important issues like usability and visibility, it has pragmatic problems with getting in the way, and most of all it has a social problem. At this point, I no longer believe that SELinux can be saved and become an important part of the Linux security landscape (at least if Linux remains commonly used).

    The fundamental reason why SELinux is beyond saving at this point is that after something like a decade of SELinux's toxic mistake, the only people who are left in the SELinux community are the true believers, the people who believe that SELinux is not a sysadmin usability nightmare, that those who disable it are fools, and so on. That your community narrows is what naturally happens when you double down on calling other people things; if people say you are an idiot for questioning the SELinux way, well, you generally leave.

  • Systemd 230 Is Upsetting Some Over Its KillUserProcess Setting

    Systemd 230 was released just last week and it has taken heat not only for opening up FBDEV to potential security issues, which already reverted, but also for changing the default behavior of user processes.

    Systemd 230 made a change where KillUserProcess defaults to yes. This terminates user processes that are part of the user session scope when the user logs out. This is causing problems for ssh-agent, screen, and other common Linux processes.

Leftovers: OSS

  • Quantifying Benefits of Network Virtualization in the Data Center
    Modern data centers have increased significantly in scale and complexity as compute and storage resources become highly virtualized. The rise of the DevOps style of application deployment means that data center resources must be agile and respond rapidly to changing workload requirements. Data center network technologies have been challenged to keep up with these rapidly evolving application requirements.
  • Apache Zeppelin Joins Several Other Projects Gaining Top-Level Status
    As we've been reporting, The Apache Software Foundation, which incubates more than 350 open source projects and initiatives, has been elevating a lot of interesting new tools to Top-Level Status recently. The foundation has also made clear that you can expect more on this front, as graduating projects to Top-Level Status helps them get both advanced stewardship and certainly far more contributions. Only a few days ago, the foundation announced that a project called TinkerPop has graduated from the Apache Incubator to become a Top-Level Project (TLP). TinkerPop is a graph computing framework that provides developers the tools required to build modern graph applications in any application domain and at any scale. Now, it has announced that Apache Zeppelin has graduated as well. Zeppelin is a web-based notebook that enables interactive data analytics.

    The world of architecture doesn't change as quickly as software, but architects are still finding new ways to share innovative designs and ideas. The open source architecture movement aims to make architectural designs, drawings, 3D renderings, and documentation freely available for integration into other projects under open source licenses. It owes much of its growth to the growing popularity of the maker movement, DIY culture, 3D printing, and CNC machines, as well as support from architects like Alejandro Aravana.

    Version 1.9 of the Rust programming language has been released. Rust is a new language with a small but enthusiastic community of developers.
  • Here's how you can make a career in OpenStack
    OpenStack is one of the biggest open source movements. It is a free and open-source software platform for cloud computing, mostly deployed as an infrastructure-as-a-service (IaaS). The software platform consists of interrelated components that control hardware pools of processing, storage, and networking resources throughout a data centre. According to the official website, hundreds of the world's largest brands rely on OpenStack to run their businesses every day, reducing costs and helping them move faster. OpenStack has a strong ecosystem globally.

It includes 33 initiatives, which among other things deal with ease of use, reuse of data, IT architecture, growth, security and digital skills, DIGST says.

Licensing and Coding

  • The Oracle v. Google Suit is Still an Anti-Open Move That Shouldn't Have Happened
    All the way back in 2010, when Oracle filed a complaint for patent and copyright infringement against Google regarding parts of the Java code found in Google's Android mobile OS, I wrote a post calling the move "the anti-open move of the year." Fast-forward to today, and in the Oracle v. Google trial that just concluded, a jury returned a verdict in Google's favor. It basically concluded that Oracle's suit against Google, claiming that the use of Java APIs in Android violated copyright law, was bunk. Now, in an op-ed piece for Ars Technica, Annette Hurst, an attorney who represented Oracle, equates the jury's decision with the death of open source. [...] Hurst makes a good point that dual licensing models are increasing, with many open source projects available for free, while commercial versions, often including support, come at a cost. But the Oracle suit originated because Oracle essentially perceived itself as owning a moat around Java that didn't really exist. [...] Indeed, one of the lasting images of this long running legal skirmish is going to be Oracle behaving in a decidedly anti-open fashion. It may have been wiser for Oracle to simply let this one go.
  • Here’s how to check if software license is open source
    The Open Source Initiative (OSI), the steward of the Open Source Definition (OSD), announced today it has created a machine readable publication of OSI approved licenses. According to the Initiative, the API will allow third parties to ‘become license-aware’, giving businesses everywhere means to determine if a license is Open Source or not.
  • 3 Things Infrastructure as Code is Not
    The role of the network engineer is changing. This is not a result of DevOps, although some would claim it is. As DevOps takes center stage in organizations, it can seem like network engineers are being asked to become developers. There have been a number of talks discussing this, some of which have surfaced at Interop Las Vegas. The shift has been Infrastructure as Code (IaC), which was fundamental to the start of the DevOps movement. So maybe you could say this is caused by DevOps.
  • Introducing Blue Ocean: a new user experience for Jenkins
    While this project is in the alpha stage of development, the intent is that Jenkins users can install Blue Ocean side-by-side with the Jenkins Classic UI via a plugin. Not all the features listed on this blog are complete but we will be hard at work over the next few months preparing Blue Ocean for general use. We intend to provide regular updates on this blog as progress is made. Blue Ocean is open source today and we invite you to give us feedback and to contribute to the project.

Security Leftovers

  • Security updates for Tuesday
  • Security challenges for the Qubes build process
    Ultimately, we would like to introduce a multiple-signature scheme, in which several developers (from different countries, social circles, etc.) can sign Qubes-produced binaries and ISOs. Then, an adversary would have to compromise all the build locations in order to get backdoored versions signed. For this to happen, we need to make the build process deterministic (i.e. reproducible). Yet, this task still seems to be years ahead of us. Ideally, we would also somehow combine this with Intel SGX, but this might be trickier than it sounds.
