The linux-aws 4.15 based kernel, which is the default kernel in the Ubuntu 18.04 LTS AMIs, is moving to a rolling kernel model. Why is this changing? The Ubuntu rolling kernel model provides the latest upstream bug fixes and performance improvements around task scheduling, I/O scheduling, networking, hypervisor guests and containers to ou

Would you like to enhance your Linux security? Do you wonder what factors should be considered when evaluating your open source security from both – the infrastructure and the application perspectives? Are you keen to learn the Ubuntu security team approach? I’ve learned that CVE patching is indeed an important puzzle, but without a struc

Linux security is central to each release of Ubuntu, the most widely-used Linux distribution. With Ubuntu’s predictable six-month release cycle, users know when to expect the latest upstream open source capabilities and security. Long Term Support (LTS) vs Interim releases Every two years in April, a Long Term Support (LTS) release is pub

In this blog, we are going to explore how to leverage MAAS for hardware discovery and kernel auto-configuration using tags. In many cases, certain pieces of hardware require extra kernel parameters to be set in order to make use of them. For example, when configuring GPU passthrough we will typically need to configure the GPU

I often need to implement tests for new ACPI tables before they become available on real hardware. Fortunately, FWTS provides a framework to read ACPI tables’ binary. The below technique is especially convenient for ACPI firmware and OS kernel developers. It provides a simple approach to verifying ACPI tables without compiling firmware an

As details of the Meltdown and Spectre vulnerabilities1 have become clearer a number of statements have been published by the multiple vendors affected; Canonical has issued advisories and updates on fixes and mitigations, the latest of which includes a first round of Spectre mitigations. However, most of these statements focus on the mec

January 09 through January 23 The Kernel Team is completely focused on addressing any Spectre and Meltdown issues as they arise. A secure Ubuntu is our top priority. No new Livepatches are being produced and our regular SRU cycles are suspended while we address Spectre and Meltdown. Spectre mitigation kernels are available. The kernels i

If you haven’t heard about last week’s Dirty COW vulnerability, I hope all of your Linux systems are automatically patching themselves…Why?  Because every single Linux-based phone, router, modem, tablet, desktop, PC, server, virtual machine, and absolutely everything in between — including all versions of Ubuntu since 2007 — was vulnerabl
