Red Hat and CentOS Fix Kernel Bug in Latest OS Versions, Urge Users to Update

Filed under

Red Hat
Security

It would appear the there was a bug in the previous Linux kernel update for the Red Hat Enterprise Linux 7.5 and CentOS Linux 7.5 releases, which was released to address the Spectre V4 security vulnerability, making connection tracking information to not function correctly, which could lead to connectivity loss and leaking of configuration properties related to the respective connection tracking into other namespaces.

"Previously, the connection tracking information was not cleared properly for packets forwarded to another network namespace," said Red Hat in an advisory. "Packets that were marked with the "NOTRACK" target in one namespace were excluded from connection tracking even in the new namespace. Consequently, a loss of connectivity occasionally occurred, depending on the packet filtering ruleset of the other network namespaces."

How to enable developer mode on a Chrome OS tablet (and install Linux using Crouton)

HowTos

Google’s Chrome OS is designed to be a relatively secure, simple operating system that’s easy to use and hard to mess up. But you can run stable channel, beta channel, or dev channel software on any Chromebook depending on whether you want the safest experience or buggy, bleeding-edge features.

There’s also an option called Developer Mode, which is different from the dev channel. It allows you to access files and settings that are normally protected and use a command shell to explore the system. It’s designed for developers and advanced users only, since it increases the chances that you’ll break your Chromebook. But enabling Developer Mode is also a prerequisite for using one my favorite Chrome OS hacks: a tool called Crouton that allows you to install Ubuntu or another GNU/Linux distribution and run it alongside Chrome OS.

Developers from the SmartOS project announced the release of build #20180705, which promises to help spread Solaris-based software on the headless server market. Most of the media attention regarding free and open-source operating systems these days focuses primarily on implementations of GNU/Linux and *BSD.

illumos, a fork of OpenSolaris, is set to take the world by storm however. It’s perhaps best known for the unusual lack of capitalization in its name, but developers are now really promoting it as a stable Unix system for extremely secure environments.

Really good to see this. SteamOS had a small update recently, which is testing the waters towards a bigger update.

If you've been wondering why SteamOS updates had been so quiet, it seems Valve has been working on updating their build infrastructure. They have another updating coming, to finally update the graphics drivers and kernel versions which will also be great to have.

Test 100+ Linux And Unix Operating Systems Online For Free

Filed under
OS

A while ago, we have covered about OSBoxes, a website that offers a collection of free, ready-to-use Linux and Unix VMs. You can download and try them on your Linux system using VirtualBox or VMWare workstation. Today, I stumbled upon a similar service named “DistroTest”. Unlike OSBoxes, DistroTest allows you to try the live Linux and Unix operating systems for free. You can test 100+ Linux and Unix operating systems online without having to install them locally. Just visit the website, choose the Linux/Unix distro of your choice and fire it up!

Two good Samaritans named Andy Klemann and Tobias Forster have hosted this web service using Debian using Qemu. There is no restrictions to use the public distros listed here. You can use all functions of the system as the way you do in your local system. You can install and uninstall software. You can test installed programs and
even delete or format the hard disk or system files. In a nutshell, DistoTest lets the distro hoppers to decide,

First impressions of PureOS

GNOME

Because it's GNOME, the desktop was immediately familiar to me. I've been a GNOME user for a long time, and I work with GNOME in testing usability of new features. So the GNOME desktop was a definite plus for me.

It's not a stock GNOME, however. PureOS uses a custom theme that doesn't use the same colors as a stock GNOME. GNOME doesn't use color very often, but I noticed this right away in the file manager. Clicking on a navigation item highlights it in a sort of rust color, instead of the usual blue.

Based on Red Hat Enterprise Linux 6.10, CentOS Linux 6.10 incorporates a new GCC (GNU Compiler Collection) update that supports retpolines to better protect users against the second variant of the well-known Spectre security vulnerability affecting billions of computers powered by modern processors.

The CentOS Linux 6.10 release also rebases the gcc-libraries, clufter, and pacemaker packages on newer upstream releases, updates the iptables-services package to read configuration files from the /etc/sysctl.d folder, and updates BIND with a new root KSK for the forthcoming DNSSEC Root Zone Key-Signing-Key rollover.

Cinnamon 4.0 Will Tackle Screen Tearing on Linux Mint

Linux Mint plans to make more performance improvements to the Cinnamon desktop ahead of its next release. Similar work featured as part of Cinnamon 3.8, released as part of Linux Mint 19, and improved the responsiveness of launching apps on the desktop. For the next major release of the Cinnamon desktop environment, the team want to tackle another performance-related bugbear: screen tearing. “On modern NVIDIA GPUs we’re able to get rid of screen tearing by using “Force Composition Pipeline” in NVIDIA-Settings. With Vsync disabled in Cinnamon we then enjoy a faster desktop environments with no screen tearing,“, writes Cinnamon’s lead developer Clement Lefebvre in a recent blog post. Read more

Launching Open Source Initiatives Is the Next Battleground In Quantum Computing

At a time when tech giants are ploughing millions of dollars in quantum computing and are striving ahead with breakthroughs, Google, Microsoft and IBM seem to be locked in an intense battle of quantum supremacy. Mountain View search giant announced Cirq — an open-source framework for NISQ computers. Cirq is an open-source initiative that allows developers to create algorithms that can run on a number of machines without having a full background in quantum physics. The Google blog notes that once installed — Cirq enables researchers to write quantum algorithms for specific quantum processors. “Cirq gives users fine-tuned control over quantum circuits, specifying gate behaviour using native gates, placing these gates appropriately on the device, and scheduling the timing of these gates within the constraints of the quantum hardware,” the blog notes. Cirq supports running these algorithms locally on a simulator and is designed to easily integrate with future quantum hardware or larger simulators via the cloud. Read more
