  • The Linux Kernel Highlights Of The 2010s From Torvalds' Sabbatical To Dealing With Vulnerabilities

    Going along with our other end of year and decade recaps, here is a look back at the Linux kernel highlights for the 2010s.

    The Linux kernel during the 2010s saw a lot of new features and expanded hardware support, fallout from many security vulnerabilities and having to provide various CPU mitigations as well, Microsoft beginning to contribute to the Linux kernel largely in the context of Hyper-V, various performance improvements, debates over the state of 32-bit's future, and much more.

  • Power Management Improvements Could Benefit Intel Server Performance In Linux 5.6

    Some Intel server platforms could see better performance with the Linux 5.6 kernel cycle.

    Intel's Rafael Wysocki who also serves as the Linux kernel's power management subsystem maintainer has been queuing some patches recently in working on ACPI _CST support around the Intel-Idle driver.

  • The AppArmor Performance Impact In 70+ Benchmarks On Linux 5.5 Git

    With bisecting one of the big regressions in Linux 5.5 and finding the culprit to be an AppArmor change while using Hackbench as one of the most affected tests, I was curious to see what other workloads are impacted big by AppArmor on the current Linux 5.5 Git code. Here are 72 tests with the Threadripper 3970X on Linux 5.5 Git when toggling AppArmor.

    These New Year's Eve benchmarks are looking at the performance of Linux 5.5 Git as of two days ago when running out-of-the-box on Ubuntu 19.10 and then booting with apparmor=0 to force AppArmor to be disabled. Thus looking at the overall cost of AppArmor on Linux 5.5 right now as opposed to just the change from the recent regression.

  • The Experimental GCN 1.0 GPU Support Might Be Dropped From AMDGPU Linux Driver

    By default the Linux kernel selects the aging Radeon DRM driver for GCN 1.0 "Southern Islands" and GCN 1.1 "Sea Islands" hardware (as well as all older ATI/AMD GPUs) while it's GCN 1.2 and newer that defaults to the modern AMDGPU kernel driver. But for years there has been experimental GCN 1.0/1.1 support available via kernel module options, but now for the original GCN GPUs that code is at risk of being dropped.

Reiser5 File-System In Development

  • Reiser5 File-System In Development - Adds Local Volumes With Parallel Scaling Out

    Well, this is a hell of a way to surprisingly end the 2010s... Reiser5. Reiser5 brings a new format to the Reiser file-system and brings some new innovations to this file-system while keeping to its controversial name.

    Edward Shishkin has continued maintaining the Reiser4 file-system over the decade for new kernel releases even with no aim for mainline inclusion. Reiser4 has continued to be maintained while the likes of Btrfs, F2FS, EXT4, XFS, and ZFS On Linux among others have continued advancing... But Shishkin has quietly been working on advancing the Reiser file-system design and today announced format 5, a.k.a. Reiser5.

Ubuntu: Pearl Linux OS Reaches Version 11, ROS 2 Humble Hawksbill, Best Linux Desktop Environment for Ubuntu 22.04 LTS

  • New release of the Ubuntu-based Pearl, 11

    Pearl Linux OS has been available for free download since 12/2014 with our first release simply titled Pearl Linux. It was based on the 14.04 released version of Ubuntu. That release was using the XFCE desktop environment. Since then we now offer the MATE, GNOME, LXDE and soon to come our own DE PearlDE which will be a mix of LXDE and XFCE4 desktops. As of the latest release Pearl OS 3.0 we are now maintaining our own repository on site. Also all tho far from ready, we are working on the new website. The forum ain't pretty but it is up and running for ya all to post any questions you may have.

  • Eat up fewer resources in Cryostat 2.1 with sidecar reports

    Cryostat is a tool for managing JDK Flight Recorder data on Kubernetes. Version 2.1 of Cryostat introduces the option of using a sidecar reports container to generate automated analysis reports for JDK flight recordings. Previously, the main Cryostat container handled the report generation. Report generation is a resource-intensive operation, and as a result, users may find themselves overprovisioning the Cryostat container to meet peak resource demands. Those resources may in turn end up unused if you're not generating reports. With this new option to delegate report generation to a sidecar container, users will find it easier to provision resources more efficiently. When report generation is not a concern, the main Cryostat container, including its web server and various lightweight operations over HTTP and JMX, has only a small resource footprint. Based on their report generation workflow, users can provision resources to the sidecar reports container accordingly and spin up any number of replicas of that container.

  • Digital transformation: 5 reality checks before you take the plunge

    Digital transformation (DX) can mean just about anything and everything in the business and technology spectrum. Starting with the transition from analog to digital, the term has evolved to refer to the adoption of social and mobile technologies and more recently, to the implementation of any of a plethora of digital technologies. With so much focus on digital, enterprises risk losing sight of what really matters: the actual transformation.

Here are some key dos and don’ts and some tips and tricks for making online and hybrid meetings more effective.

Security Leftovers

  • Twisted Panda: Chinese APT espionage operation against Russian’s state-owned defense institutes - Check Point Research [Ed: Microsoft Windows TCO]

    In the past two months, we observed multiple APT groups attempting to leverage the Russia and Ukraine war as a lure for espionage operations. It comes as no surprise that Russian entities themselves became an attractive target for spear-phishing campaigns that are exploiting the sanctions imposed on Russia by western countries. These sanctions have put enormous pressure on the Russian economy, and specifically on organizations in multiple Russian industries. [...] The malware creates a working directory %TEMP%\\OfficeInit and copies to it INIT and cmpbk32.dll files, as well as a legitimate 32-bit Windows executable cmdl32.exe from either System32 or SysWOW64 folder, depending on if the operating system is 32 or 64 bit.

  • 747 Hackathon | Pen Test Partners

    As is probably clear from our blog and public talks aviation cyber security is an area of huge interest to us. Some of us are also light aircraft pilots, so the crossover of two of our loves makes for some fascinating research. Over the last few years we’ve managed to get access to several airplanes that have been recently retired. As the various breakers yards are backed up with planes retired during the pandemic, many fully functional planes are available that will never fly again. However, a big problem for us is that the planes get dismantled, often between visits. On several occasions we’ve gone to an airframe to figure out the on board systems, go back to the lab to prepare custom connectors and tools, then come back a month later to find out that it’s been taken apart into many many pieces.

openSUSE: Mesa, ImageMagick Packages Update in Tumbleweed

Snapshots for openSUSE Tumbleweed have been continuously released this month. This week we will look at packages released in four snapshots since Friday. However, before venturing in to those snapshots, there is a change to NetworkManager expected to arrive in a soon-to-be-released snapshot; it will provide a fix for the wifi chunk changes made in a prior snapshot that caused some connectivity challenges for some users. The advantages of snapper with Btrfs can keep openSUSE’s rolling release users connected through a rollback; users can then update next week and not skip a beat. The most recent snapshot, 20220523, provided three package updates. Among those were an update to secure communications library gnutls 3.7.5; the package was laying the ground for a future release by adding options to disable session ticket usage in TLS 1.2 because it does not provide forward confidentiality; TLS 1.2 has future backward incompatibility. The other two packages to update in the snapshot were libxkbcommon 1.4.1 and python-sympy 1.10.1, which removed the long deprecated densearith, densesolve, and densetools. Read more
