Red Hat
Security

The new Linux kernel security update is marked by the Red Hat Product Security team as having an "Important" security impact due to the fact that it patches several critical flaws, including the Spectre SWAPGS gadget vulnerability (CVE-2019-1125) affecting x86 processors.

Also patched are a security vulnerability (CVE-2019-5489) leading to page cache side-channel attacks, an issue in the Salsa20 encryption algorithm that could allow local attackers to cause a denial of service (CVE-2017-17805), and a flaw (CVE-2018-17972) that let unprivileged users inspect kernel stacks of arbitrary tasks.

Red Hat/Fedora: Flock’19 Budapest, Cockpit 201 and Systemd 243 RC2

Filed under
Red Hat
  • Flock’19 Budapest

    This was the first occurrence of the conference for me to attend. Its an annual Fedora Community gathering, which happens in a new city of Europe every year. This time it was in Budapest, the capital of Hungary, last year it was hosted in Dresden. Dates for the same were: 8th Aug through 11th Aug 2019. Also I got an opportunity to present there on my proposal: “Getting Started with Fedora QA”.

    Day 1 Started with a Keynote by Mathew Miller (mattdm). In here he spoke about where we as a community are and where we need to go further. It was a knowledgeable discussion for a first timer like me who was always looking out for the Vision and Mission of Fedora community. There are people who are with Fedora since its first release and you get to meet them here at the annual gathering.

    [...]

    Groups were formed and people decided for themselves where they wanted to go for the evening hangout on the Day 1. We were 7 people who decided to hangout at the Atmosphere Klub near the V.Kerulet and left at around 9:00 pm by walk.

    Day 2 started with a keynote by Denise Dumas, Vice President, Operating System Platform, Red Hat. She spoke on “Fedora, Red Hat and IBM”. I woke up late, 20 minutes before the first session as I went to bed late last night and had walked for around 11 kms the day before.

  • Fedora 30 : Set up the Linux Malware Detect.
  • Cockpit 201

    It’s now again possible to stop a service, without disabling it. Reloading is now available only when the service allows it.

    Furthermore, disabling or masking a service removes any lingering “failed” state, reducing noise.

  • Systemd 243 RC2 Released

    Released nearly one month ago was the systemd 243 release candidate while the official update has yet to materialize. It looks though like it may be on the horizon with a second release candidate being posted today.

    Red Hat's Zbigniew Jędrzejewski-Szmek has just tagged systemd 243-RC2 as the newest test release for this new version of this de facto Linux init system. Over the past month have been new hardware database (HWDB) additions, various fixes, new network settings, resolvectl zsh shell completion support, bumping timedated to always run at the highest priority, and other changes.

  • Troubleshooting Red Hat OpenShift applications with throwaway containers

    Imagine this scenario: Your cool microservice works fine from your local machine but fails when deployed into your Red Hat OpenShift cluster. You cannot see anything wrong with the code or anything wrong in your services, configuration maps, secrets, and other resources. But, you know something is not right. How do you look at things from the same perspective as your containerized application? How do you compare the runtime environment from your local application with the one from your container?

    If you performed your due diligence, you wrote unit tests. There are no hard-coded configurations or hidden assumptions about the runtime environment. The cause should be related to the configuration your application receives inside OpenShift. Is it time to run your app under a step-by-step debugger or add tons of logging statements to your code?

    We’ll show how two features of the OpenShift command-line client can help: the oc run and oc debug commands.

  • What piece of advice had the greatest impact on your career?

    I love learning the what, why, and how of new open source projects, especially when they gain popularity in the DevOps space. Classification as a "DevOps technology" tends to mean scalable, collaborative systems that go across a broad range of challenges—from message bus to monitoring and back again. There is always something new to explore, install, spin up, and explore.

  • How DevOps is like auto racing

    When I talk about desired outcomes or answer a question about where to get started with any part of a DevOps initiative, I like to mention NASCAR or Formula 1 racing. Crew chiefs for these race teams have a goal: finish in the best place possible with the resources available while overcoming the adversity thrown at you. If the team feels capable, the goal gets moved up a series of levels to holding a trophy at the end of the race.

    To achieve their goals, race teams don’t think from start to finish; they flip the table to look at the race from the end goal to the beginning. They set a goal, a stretch goal, and then work backward from that goal to determine how to get there. Work is delegated to team members to push toward the objectives that will get the team to the desired outcome.

    [...]

    Race teams practice pit stops all week before the race. They do weight training and cardio programs to stay physically ready for the grueling conditions of race day. They are continually collaborating to address any issue that comes up. Software teams should also practice software releases often. If safety systems are in place and practice runs have been going well, they can release to production more frequently. Speed makes things safer in this mindset. It’s not about doing the “right” thing; it’s about addressing as many blockers to the desired outcome (goal) as possible and then collaborating and adjusting based on the real-time feedback that’s observed. Expecting anomalies and working to improve quality and minimize the impact of those anomalies is the expectation of everyone in a DevOps world.

  • Deep Learning Reference Stack v4.0 Now Available

    Artificial Intelligence (AI) continues to represent one of the biggest transformations underway, promising to impact everything from the devices we use to cloud technologies, and reshape infrastructure, even entire industries. Intel is committed to advancing the Deep Learning (DL) workloads that power AI by accelerating enterprise and ecosystem development.

    From our extensive work developing AI solutions, Intel understands how complex it is to create and deploy applications for deep learning workloads.

low-memory-monitor: new project announcement

Filed under
Linux
Red Hat

I'll soon be flying to Greece for GUADEC but wanted to mention one of the things I worked on the past couple of weeks: the low-memory-monitor project is off the ground, though not production-ready.

low-memory-monitor, as its name implies, monitors the amount of free physical memory on the system and will shoot off signals to interested user-space applications, usually session managers, or sandboxing helpers, when that memory runs low, making it possible for applications to shrink their memory footprints before it's too late either to recover a usable system, or avoid taking a performance hit.

It's similar to Android's lowmemorykiller daemon, Facebook's oomd, Endless' psi-monitor, amongst others

  • The Linux Foundation Announces New Open Hardware Technologies and Collaboration

    The Linux Foundation, the nonprofit organization enabling mass innovation through open source, today announced that the OpenPOWER Foundation will become a project hosted at The Linux Foundation. The project includes IBM’s open POWER Instruction Set Architecture (ISA) and contributed Source Design Implementations required to support data-driven hardware for intensive workloads like Artificial Intelligence (AI).

    OpenPOWER is the open steward for the Power Architecture and has the support of 350 members, including IBM, Google, Inspur Power Systems, Yadro, Hitachi, Wistron, Mellanox, NVIDIA, and Red Hat.

    The governance model within the Linux Foundation gives software developers assurance of compatibility while developing AI and hybrid cloud native applications that take advantage of POWER’s rich feature set and open compute hardware and software ecosystems.

    As the demand rises for more and more compute-intensive workloads like AI and in-memory analytics, commodity systems vendors have struggled with the looming predictions of the end of Moore’s Law. Central processing units (CPUs) may no longer handle the rising demands alone, and data-centric systems are built to maximize the flow of data between CPUs and attached devices for specialized workloads. By hosting OpenPOWER at The Linux Foundation, a cross-project, cross-community collaboration, it will accelerate development of hardware and software to support data-centric systems, by making it available to a growing global audience.

    “The OpenPOWER community has been doing critical work to support the increasing demands of enterprises that are using big data for AI and machine learning workloads. The move to bring these efforts together with the worldwide ecosystem of open source developers across projects at The Linux Foundation will unleash a new level of innovation by giving developers everywhere more access to the tools and technologies that will define the next generation of POWER architecture,” said Jim Zemlin, executive director at The Linux Foundation.

  • Raptor Computing Systems Planning To Launch New ATX POWER9 Board With OpenCAPI

    In addition to the news out of the OpenPOWER Summit in San Diego that the POWER ISA is going open-source and the OpenPOWER Foundation becoming part of the Linux Foundation, Raptor Computing Systems shared they plan to launch a new standard ATX motherboard next year that will feature OpenCAPI connectivity.

    Built off the successes of their Talos II high-end server motherboard and lower-cost Blackbird desktop motherboard designs, there is apparently a new motherboard design for POWER9 being worked on that could launch in early 2020.

  • OpenPOWER Foundation | The Next Step in the OpenPOWER Foundation Journey

    Today marks one of the most important days in the life of the OpenPOWER Foundation. With IBM announcing new contributions to the open source community including the POWER Instruction Set Architecture (ISA) and key hardware reference designs at OpenPOWER Summit North America 2019, the future has never looked brighter for the POWER architecture.

    OpenPOWER Foundation Aligns with Linux Foundation

    The OpenPOWER Foundation will now join projects and organizations like OpenBMC, CHIPS Alliance, OpenHPC and so many others within the Linux Foundation. The Linux Foundation is the premier open source group, and we’re excited to be working more closely with them.

    Since our founding in 2013, IEEE-ISTO has been our home, and we owe so much to its team. It’s as a result of IEEE-ISTO’s support and guidance that we’ve been able to expand to more than 350 members and that we’re ready to take the next step in our evolution. On behalf of our membership, our board of directors and myself, we place on record our thanks to the IEEE-ISTO team.

    By moving the POWER ISA under an open model – guided by the OpenPOWER Foundation within the Linux Foundation – and making it available to the growing open technical commons, we’ll enable innovation in the open hardware and software space to grow at an accelerated pace. The possibilities for what organizations and individuals will be able to develop on POWER through its mature ISA and software ecosystem will be nearly limitless.

  • How Red Hat delivers $7B in customer savings

    This spring, Red Hat commissioned IDC to conduct a new study to analyze the contributions of Red Hat Enterprise Linux to the global business economy. While many of the findings were impressive, including immense opportunities for partners, we were especially excited to learn more about how our customers benefit from Red Hat Enterprise Linux.

    According to the study, the world’s leading enterprise Linux platform "touches" more than $10 trillion of business revenues worldwide each year and provides economic benefits of more than $1 trillion each year to customers. Nearly $7 billion of that number comes in the form of IT savings. Even more exciting? As hybrid cloud adoption grows, we expect customers to continue to benefit given the importance of a common, flexible and open operating system to IT deployments that span the many footprints of enterprise computing.

  • Living my best 4 days: Flock to Fedora 2019

    Months of waiting came to an end and finally, it was time to meet people with whom I have been working for the last 4 months, being on the other side of the screen. Things seemed different when our last Wednesday conference call ended with “Meet you soon” instead of a “Good Day”. The excitement of attending Flock to Fedora, was not only because the virtual interaction is turning to the real meeting but also, it was my first ever International trip. With approaching the 6th of August, the fear of travelling solo was getting on the peak, and at one moment I started questioning if all the trouble I underwent during last month was even worth it. But the time I met Shraddha(another intern working on the same project)at Bangalore airport, we happened to click so much at our first conversation that it was certain that at least my journey will not be me, and my headphones all the time.

    Since I reached Budapest a day before when everyone arrived, I got a handful of time discovering places, getting to know their culture and try on things we never tried before. The excitement of being at such a beautiful place did not make me realise that I was sleep-deprived, I had a jet lag of 4 hours and I was hungry. I spent the entire day roaming the streets, enjoying a breath of fresh air and exploring the city and ways of commute as well.

    Next day we shifted to the hotel that was booked for us and where the conference will be held. The ambience of the whole place was really nice and we met other fellow attendees at the conference.

I am working on integrating it in to the build workflow for Fedora but also allow package maintainers to use it locally as a build linter of sorts. Here is a link to the presentation I gave. I think there is video, but I am not sure where those are.

Linux commands to display your hardware information

There are many reasons you might need to find out details about your computer hardware. For example, if you need help fixing something and post a plea in an online forum, people will immediately ask you for specifics about your computer. Or, if you want to upgrade your computer, you'll need to know what you have and what you can have. You need to interrogate your computer to discover its specifications. Alternatively, you could open up the box and read the labels on the disks, memory, and other devices. Or you could enter the boot-time panels—the so-called UEFI or BIOS panels. Just hit the proper program function key during the boot process to access them. These two methods give you hardware details but omit software information. Or, you could issue a Linux line command. Wait a minute… that sounds difficult. Why would you do this? Read more

Feh is a light-weight command-line image viewer for Linux

The default image viewer in most Linux distros is a fine option for many users, but if you want a distraction free alternative, Feh is a good option. Feh's interface is as barebones as it gets as it does not have any toolbars or buttons but is a command line interface application; because of that, it is very light on resources and still easy enough to use even for users who shy away from using the command line whenever possible.
