Linux Kernel and Security: LVM2, Containers, AMD

  • LVM2 Begins Work On Major Changes To Logical Volume Management

    LVM2 as the user-space tools for Logical Volume Management (LVM) on Linux is in the process of going through a big re-work.

  • Containers and Cloud Security

    The idea behind this blog post is to take a new look at how cloud security is measured and what its impact is on the various actors in the cloud ecosystem. From the measurement point of view, we look at the vertical stack: all code that is traversed to provide a service all the way from input web request to database update to output response potentially contains bugs; the bug density is variable for the different components but the more code you traverse the higher your chance of exposure to exploitable vulnerabilities. We’ll call this the Vertical Attack Profile (VAP) of the stack. However, even this axis is too narrow because the primary actors are the cloud tenant and the cloud service provider (CSP). In an IaaS cloud, part of the vertical profile belongs to the tenant (The guest kernel, guest OS and application) and part (the hypervisor and host OS) belong to the CSP. However, the CSP vertical has the additional problem that any exploit in this piece of the stack can be used to jump into either the host itself or any of the other tenant virtual machines running on the host. We’ll call this exploit causing a failure of containment the Horizontal Attack Profile (HAP). We should also note that any Horizontal Security failure is a potentially business destroying event for the CSP, so they care deeply about preventing them. Conversely any exploit occurring in the VAP owned by the Tenant can be seen by the CSP as a tenant only problem and one which the Tenant is responsible for locating and fixing. We correlate size of profile with attack risk, so the large the profile the greater the probability of being exploited.

  • Canonical Releases AMD Microcode Updates for All Ubuntu Users to Fix Spectre V2

    Canonical released a microcode update for all Ubuntu users with AMD processors to address the well-known Spectre security vulnerability.

    The Spectre microprocessor side-channel vulnerabilities were publicly disclosed earlier this year and discovered to affect billions of devices made in the past two decades. Unearthed by Jann Horn of Google Project Zero, the second variant (CVE-2017-5715) of the Spectre vulnerability is described as a branch target injection attack.

Programming: 5 Pillars of Learning Programming, New Releases of Rust and Git

  • 5 Pillars of Learning Programming

    Learning how to program is hard. I often find that university courses and boot camps miss important aspects of programming and take poor approaches to teaching rookies.

    I want to share the 5 basic pillars I believe a successful programming course should build upon. As always, I am addressing the context of mainstream web applications.

    A rookie’s goal is to master the fundamentals of programming and to understand the importance of libraries and frameworks.

    Advanced topics such as the cloud, operations in general, or build tools should not be part of the curriculum. I am also skeptical when it comes to Design Patterns. They presume experience that beginners never have.

  • The Rust Programming Language Blog: Announcing Rust 1.27

    The Rust team is happy to announce a new version of Rust, 1.27.0. Rust is a systems programming language focused on safety, speed, and concurrency.

  • Rust 1.27 Released With SIMD Improvements

    Most notable to Rust 1.27 is SIMD support via the std::arch module to make use of SIMD (Single Instruction, Multiple Data) instructions directly. Up to now Rust could already make use of LLVM's auto-vectorization support, but this lets Rust developers write SIMD instructions on their own and to allow for the proper Rust code to be executed based upon the CPU at run-time.

  • Git 2.18 Released With Initial Version Of Its New Wire Protocol

    Version 2.18 of the Git distributed revision control system is now available.

    Arguably most notable about Git 2.18 is the introduction of its new wire protocol "protocol_v2" that is designed to offer much greater performance. This new protocol is designed to be much faster and is already being used at Google and elsewhere due to the significant performance benefits.

  • Git v2.18.0

    The latest feature release Git v2.18.0 is now available at the usual places. It is comprised of 903 non-merge commits since v2.17.0, contributed by 80 people, 24 of which are new faces.

  • Heather Kirksey on Integrating Networking and Cloud Native

    As highlighted in the recent Open Source Jobs Report, cloud and networking skills are in high demand. And, if you want to hear about the latest networking developments, there is no one better to talk with than Heather Kirksey, VP, Community and Ecosystem Development, Networking at The Linux Foundation. Kirksey was the Director of OPNFV before the recent consolidation of several networking-related projects under the new LF Networking umbrella, and I spoke with her to learn more about LF Networking (LFN) and how the initiative is working closely with cloud native technologies.

    Kirksey explained the reasoning behind the move and expansion of her role. “At OPNFV, we were focused on integration and end-to-end testing across the LFN projects. We had interaction with all of those communities. At the same time, we were separate legal entities, and things like that created more barriers to collaboration. Now, it’s easy to look at them more strategically as a portfolio to facilitate member engagement and deliver solutions to service providers.”

  • Linux Skills Most Wanted: Open Source Jobs Report

    The 2018 Open Source Technology Jobs Report shows rapid growth in the demand for open source technical talent, with Linux skills a must-have requirement for entry-level positions.

    The seventh annual report from The Linux Foundation and Dice, released Wednesday, identifies Linux coding as the most sought-after open source skill. Linux-based container technology is a close second.

    The report provides an overview of open source career trends, factors motivating professionals in the industry, and ways employers attract and retain qualified talent. As with the last two open source jobs reports, the focus this year is on all aspects of open source software and is not limited to Linux.

Flatpak 1.0 Linux Application Sandboxing & Distribution Framework Is Almost Here

Filed under
Linux

While it's becoming very popular among Linux users as it is more and more adopted by Linux OS vendors, Flatpak is still considered an "under development" technology, and so it's not yet promoted on a mass scale as its rival Snap is by Ubuntu's mother company Canonical.

However, Flatpak as it is right now, it's very usable, but it is yet to achieve the 1.0 version milestone, which usually marks a project as mature and ready for mass deployment. And it's now more closer than ever as the development team announced today the availability of the first Flatpak 1.0 pre-release version.

  • Congatec teams up with OSADL for real-time Linux

    In a first step, OSADL qualified congatec’s latest real-time Linux implementation that uses Linux kernel 4.9.47-rt37 on conga-TS170 Server-on-Modules equipped with the embedded server-class Intel Xeon processor (E3-1578L v5 at 2.00GHz). The challenge when implementing hard real-time Linux behaviour lies in mastering all processing layers from BIOS to Linux kernel to user space, since the overall real-time capabilities are only as good as the weakest link in the chain. In addition, modern processors such as Intel’s Skylake family offer a wide range of energy saving features that must be balanced to the requirements of real-time computing. Executed in standardized racks, the OSADL quality assurance testifies that conga-TS170 Server-on-Modules are perfect for any real-time application. The boards support all major real-time capable OS from both x86 and ARM technologies. These include first and foremost real-time Linux but also further RTOS such as VxWorks or QNX, as well as deterministic hypervisor and virtualization technologies from vendors such as Real-Time Systems.

  • Zapcc high-speed C++ compiler now open source

    Zapcc, a caching C++ compiler built for speed, has gone open source.

    Ceemple Software, Zapcc’s builder, claims the compiler offers dramatic improvements in both incremental and full builds compared to building with Clang 4.0 and Clang 5.0. Based on heavily modified code from the Clang compiler project, Zapcc uses an in-memory compilation cache in a client-server architecture. All compilation information is remembered between runs.

  • Heterogeneous memory management meets EXPORT_SYMBOL_GPL()

    One of the many longstanding — though unwritten — rules of kernel development is that infrastructure is not merged until at least one user for that infrastructure exists. That helps developers evaluate potential interfaces and be sure that the proposed addition is truly needed. A big exception to this rule was made when the heterogeneous memory management (HMM) code was merged, though. One of the reasons for the lack of users in this case turns out to be that many of the use cases are proprietary; that has led to some disagreements over the GPL-only status of an exported kernel symbol.

    The HMM subsystem exists to support peripherals that have direct access to system memory through their own memory-management units. It allows the ownership of ranges of memory to be passed back and forth and notifies peripherals of changes in memory mappings to keep everything working well together. HMM is not a small or simple subsystem, and bringing it into the kernel has forced a number of low-level memory-management changes. After a multi-year development process, the core HMM code was merged for the 4.14 kernel, despite the lack of any users.

    Unified Modeling Language (UML) is a general-purpose, modeling language designed to provide a standard way for visualizing, specifying, constructing, and documenting the artifacts of distributed object systems. It’s the industry standard modeling language for software engineering.

    The aim of UML is to give software engineers, agile and small development teams, and system architects useful tools for analysis, design, and implementation of software-based systems. It also provides modeling business and similar processes. The language helps to visualize your object-oriented design and communicate with others. It offers limited use for other programming paradigms.

Now PulseAudio makes the audio buffer in the kernel much smaller, which reduces the problem a lot.
