Linux 4.18 RC2 Released From China

Filed under
Linux
  • Linux 4.18-rc2

    Another week, another -rc.

    I'm still traveling - now in China - but at least I'm doing this rc Sunday
    _evening_ local time rather than _morning_. And next rc I'll be back home
    and over rmy jetlag (knock wood) so everything should be back to the
    traditional schedule.

    Anyway, it's early in the rc series yet, but things look fairly normal.
    About a third of the patch is drivers (drm and s390 stand out, but here's
    networking and block updates too, and misc noise all over).

    We also had some of the core dma files move from drivers/base/dma-* (and
    lib/dma-*) to kernel/dma/*. We sometimes do code movement (and other
    "renaming" things) after the merge window simply because it tends to be
    less disruptive that way.

    Another 20% is under "tools" - mainly due to some selftest updates for
    rseq, but there's some turbostat and perf tooling work too.

    We also had some noticeable filesystem updates, particularly to cifs. I'm
    going to point those out, because some of them probably shouldn't have
    been in rc2. They were "fixes" not in the "regressions" sense, but in the
    "missing features" sense.

    So please, people, the "fixes" during the rc series really should be
    things that are _regressions_. If it used to work, and it no longer does,
    then fixing that is a good and proper fix. Or if something oopses or has a
    security implication, then the fix for that is a real fix.

    But if it's something that has never worked, even if it "fixes" some
    behavior, then it's new development, and that should come in during the
    merge window. Just because you think it's a "fix" doesn't mean that it
    really is one, at least in the "during the rc series" sense.

    Anyway, with that small rant out of the way, the rest is mostly arch
    updates (x86, powerpc, arm64, mips), and core networking.

    Go forth and test. Things look fairly sane, it's not really all that
    scary.

    Shortlog appended for people who want to scan through what changed.

Kernel: Systemd, AMDGPU Driver and LKML archives

  • Escape from System D, episode V

    I think what really bothers me is just the scope of the thing. Systemd isn’t an init system; it’s a software ecosystem, a whole slew of separate programs which are designed to work together and to manage various different aspects of the system, not simply just manage services. The problem is, despite the claims of modularity, it’s somewhat difficult to separate out the pieces. Right from the start, building Systemd, you have a number of dependencies and a huge set of components that you may or may not be able to disable; if you do disable certain components, it’s not clear what the ramifications might be, whether you need to replace them, and what you might be able to replace them with. I’d be less bothered if I could download a source bundle just for “Systemd, the init daemon” and compile that separately, and pick and choose the other parts on an individual basis in a similar way, but that’s just not possible – and this is telling; sure, it’s “modular” but clearly the modules are all designed to be used together. In theory you may be able to take the core and a few select pieces but none of the distributions are doing that and therefore it’s not clear that it really is possible.

    Less than one week after the close of the Linux 4.18 kernel merge window, AMD developers working on the AMDGPU Direct Rendering Manager driver have already submitted their first batch of changes to DRM-Next to begin queuing for the Linux 4.19 kernel cycle. There are a few new features with this latest batch of code.

  • LKML archives on lore.kernel.org

    A new archive of linux-kernel mailing list (LKML) posts going back to 1998 is now available at lore.kernel.org. It is based on public-inbox (which we looked at back in February. Among other things, public-inbox allows retrieving the entire archive via Git: "Git clone URLs are provided at the bottom of each page. Note, that due to its volume, the LKML archive is sharded into multiple repositories, each roughly 1GB in size. In addition to cloning from lore.kernel.org, you may also access these repositories on git.kernel.org." The full announcement, which includes information about a new Patchwork instance as well as ways to link into the new archive, can be found on kernel.org.

Most secure Linux distros in 2018

Linux
Security

Think of a Linux distribution as a bundle of software delivered together, based on the Linux kernel - a kernel being the core of a system that connects software to hardware and vice versa – with a GNU operating system and a desktop environment, giving the user a visual way to operate the system via a graphical user interface.

Linux has a reputation as being more secure than Windows and Mac OS due to a combination of factors – not all of them about the software.

Firstly, although desktop Linux users are on the up, Linux environments are far less common in the grand scheme of things than Windows devices on personal computers. The Linux community also tends to be more technical. There are technical reasons too, including fundamental differences in the way the distribution architecture tends to be structured.

Nevertheless over the last decade security-focused distributions started to appear, which will appeal to the privacy-conscious user who wants to avoid the worldwide state-sanctioned internet spying that the west has pioneered and where it continues to innovate. Of course, none of these will guarantee your privacy, but they're a good start. Here we list some of them.

It is worth noting that security best practices are often about process rather than the technology, avoiding careless mistakes like missing patches and updates, and using your common sense about which websites you visit, what you download, and what you plug into your computer.

Linux

Seco unveiled a pair Qseven modules that run Linux or Android and offer optional industrial temp support. The Q7-C25 uses NXP’s quad -A53 i.MX8M while the Q7-C26 features the i.MX8Quad, which adds up to 2x -A72 cores. Starter kits are also available.

At Computex earlier this month, Seco showed off two 70 x 70mm Qseven 1.2 modules that are still listed as being “under development.” The i.MX8M based Q7-C25 and i.MX8Quad based Q7-C26 run Linux and Android, and are available in 0 to 60°C and -40 to 85°C models. The 5V modules have many similar features, but the Q7-C26 based on the more powerful, up to hexa-core i.MX8Quad adds some extras such as SATA III support.

PureOS – A User Friendly, Secure and Freedom Respecting OS

Reviews

PureOS is a modern user-friendly Debian-based distro that uses exclusively free and open source software and it has the endorsement of the Free Software Foundation.

It’s said to have the best privacy-protecting apps that it ships with – which I guess is evident since I haven’t experienced any significant pop-ups yet.

On the whole, PureOS looks familiar owing to the fact that it runs GNOME desktop. Its screen is clutter free and being Debian-based, its operations and window functions are similar to that of Ubuntu.

Below is my list of its main features and why I will rate it.

  • 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.

KDE: Qt, Plasma, QML, Usability & Productivity

  • Qt 5.11.1 and Plasma 5.13.1 in ktown ‘testing’ repository
    A couple of days ago I recompiled ‘poppler’ and the packages in ‘ktown’ that depend on it, and uploaded them into the repository as promised in my previous post. I did that because Slackware-current updated its own poppler package and mine needs to be kept in sync to prevent breakage in other parts of your Slackware computer. I hear you wonder, what is the difference between the Slackware poppler package and this ‘ktown’ package? Simple: my ‘poppler’ package contains support for Qt5 (in addition to the QT4 support in the original package) and that is required by other packages in the ‘ktown’ repository.

Programming: Python Maths Tools and Java SE

  • Essential Free Python Maths Tools
    Python is a very popular general purpose programming language — with good reason. It’s object oriented, semantically structured, extremely versatile, and well supported. Scientists favour Python because it’s easy to use and learn, offers a good set of built-in features, and is highly extensible. Python’s readability makes it an excellent first programming language. The Python Standard Library (PSL) is the the standard library that’s distributed with Python. The library comes with, among other things, modules that carry out many mathematical operations. The math module is one of the core modules in PSL which performs mathematical operations. The module gives access to the underlying C library functions for floating point math.

Big Red’s called this a Java SE Subscription and pitched it as “a commonly used model, popular with Linux distributions”. The company also reckons the new deal is better than a perpetual licence, because they involve “an up-front cost plus additional annual support and maintenance fees.”
