  • Analyzing the Linux boot process

    The oldest joke in open source software is the statement that "the code is self-documenting." Experience shows that reading the source is akin to listening to the weather forecast: sensible people still go outside and check the sky. What follows are some tips on how to inspect and observe Linux systems at boot by leveraging knowledge of familiar debugging tools. Analyzing the boot processes of systems that are functioning well prepares users and developers to deal with the inevitable failures.

  • BPF Getting Error Injection & More In Linux 4.16

    While BPF has been under the spotlight recently in light of Spectre, with the upcoming Linux 4.16 cycle this in-kernel virtual machine and originally packet filter will be picking up new features.

  • Jailhouse Guest Support Queued For Linux 4.16

    Yet more functionality to find with the upcoming Linux 4.16 kernel is the first bits of Jailhouse hypervisor functionality being mainlined.

    Since at least 2013 Siemens has been developing the Jailhouse hypervisor for Linux systems. This partitioning hypervisor aims to be lighter than KVM and Siemens has been designing it for "highly demanding real-time, safety or security" workloads.

  • Retpoline patch coming to Linux 4.9 and Linux 4.14

    Several Linux kernel versions, including 4.9, 4.14, and the upcoming 4.15, will have Retpoline support built in to mitigate against the Spectre vulnerability. Greg Kroah-Hartman, one of the head honchos overlooking kernel development, accepted the patch into the 4.9 and 4.14 kernels meaning Linux users everywhere should be secure from Spectre without any performance hits.

    The exact kernel versions to look out for are 4.9.77 and 4.14.14. Unfortunately, for those of us still on Linux 4.4 and 3.18, which are still supported, there is no sign of the Retpoline patch just yet despite getting receiving other updates. Hopefully it’ll be released in a subsequent update after they’ve had time to monitor for any problems in 4.9 and 4.14.

  • Retpoline Support Backport Lands In GCC 7

    The backporting of -mindirect-branch, -mindirect-return and -mindirect-branch-register, a.k.a. the GCC "Retpoline" patches, have been back-ported and merged into the GCC 7 branch.

    Given the severity of the Spectre vulnerability, these features for Retpoline support are being back-ported to GCC branches normally only reserved for bug/regression/documentation fixes.

  • Linux kernel mailing list back online; Meltdown and Spectre vulnerabilities; Mobile OS eelo; Barcelona now using Linux

    The popular Linux Kernel Mailing List website is back online after going down and staying down for several days due to a power outage to the home server where it was hosted. Upon reboot, a password (for dm-crypt) was required to mount the root device; however, that in itself was not the problem. The problem was the fact that the PC’s owner, Jasper, was on vacation when all of this occurred. Anyway, the site is now back up and continuing to operate as it always has.

    Speaking of the kernel mailing lists, Johannes Weiner issued a call for proposals for agenda topics to the upcoming annual 2018 Linux Storage, Filesystem and Memory Management (LSF/MM) Summit. The deadline is January 31, 2018, and the summit will be held between April 23-25 At Deer Valley Lodges in Park City, Utah. For more information, visit the Linux Foundation Events page.

Barcelona is moving to Linux; why not Dhaka?

Filed under

Linux

The Spanish city of Barcelona just announced a few days ago (https://www.itwire.com/open-source/81377-barcelona-plans-move-to-open-source-software.html) that it has successfully completed a pilot project of moving 1,000 desktops of municipality employees from Microsoft Windows and MS Office to free/open-source alternatives, Ubuntu Linux (www.ubuntu.com/desktop) and LibreOffice (www.libreoffice.org).

The question is why countries like Bangladesh, which are much less wealthy than Spain, are not making similar moves to replace expensive Microsoft software with free/open-source alternatives.

The simple fact is that there is almost no awareness of the real cost of Microsoft software in Bangladesh, as software piracy is so commonplace. Every market has shops stocking pirated MS Windows/MS Office DVDs; so the public can be forgiven for thinking that these are practically free of cost.

  • Reasons to Get Excited about KDE in 2018
  • Three old Plasma Weather applet TODO items gone for Plasma 5.12

    Just when I thought to have missed yet another Plasma feature freeze deadline with the one for Plasma 5.12 LTS and thus a good(?) excuse to re-decrease priority of some planned work on the Plasma Addons Weather applet (from the kdeplasma-addons repo, not to be mixed up with clearmartin’s one from github/store.kde.org) once more and thus delay things even further to a day that may never come, the Plasma team found they need to shift the deadline by some weeks to be after the KDE Frameworks 5.42.0 release.
    So excuse gone, no other quickly found… time to do a git pull and open the editor.

  • Plasma on ARM: State of the Union

    For the past year at Blue Systems my colleagues and I have been working on getting Plasma 5 ready for ARMv8 systems such as the Pinebook. If you were at QtCon this year, you might have also seen our awesome team demo’ing these systems at the KDE booth along with Plasma on ARMv7 systems such as the ODROID C1.

    The Consumer Electronics Show (CES) is an odd place to announce an enterprise product, but the Wi-Fi Alliance used the massive trade show — which has more or less taken over where Comdex left off — to announce a major upgrade to Wi-Fi security.

    The alliance announced the Wi-Fi Protected Access 3 (WPA3), a new standard of Wi-Fi security that greatly increases the security capabilities of the wireless standard. WPA2, which is the current standard in wireless security, has been around for 14 years, so this is way overdue.

    The initial system we set up was only ever intended to be minimally viable and has not scaled well, although that’s probably to be expected. There’s been quite a lot of growing pains so I’ve been tasked with taking it to the next level.

    GNOME Shell extensions are small and lightweight pieces of codes that enhance GNOME desktop’s functionality and improves the user experience. They are the equivalent of add-ons in your browser. For instance, you can have add-ons that download videos like IDM downloader or block annoying ads such as Adblocker.

    Similarly, GNOME extensions perform certain tasks e.g. Display weather and geolocation. One of the tools used to install and customize GNOME Shell extensions is the GNOME tweak tool. It comes pre-installed in the latest Linux distributions. This article we cover how to install GNOME Shell extensions from GUI and from the command line on various Linux distros.

  • Musings on bug trackers

    I love bugzilla, I really do. I’ve used it nearly my entire career in free software. I know it well, I like the command line tool integration. But I’ve never had a day in bugzilla where I managed to resolve/triage/close nearly 100 issues. I managed to do that today with our gitlab instance and I didn’t even mean to.

  • Open Source turns 20

    While open source software is ubiquitous, recognized across industries as a fundamental infrastructure component as well as a critical factor for driving innovation, the "open source" label was coined only 20 years ago.

    The concept of open source software - as opposed to free software or freeware - is credited to Netscape which, in January 1998, announced plans to release the source code of its proprietary browser, Navigator, under a license that would freely permit modification and redistribution. This code is today the basis for Mozilla Firefox and Thunderbird.

    The Open Source Initiative (OSI) regards that event as the point at which "software freedom extended its reach beyond the enthusiast community and began its ascent into the mainstream".

  • Percona Announces Sneak Peek of Conference Breakout Sessions for Seventh Annual Percona Live Open Source Database Conference
  • The Universal Donor

    A few people reacted negatively to my article on why Public Domain software is broadly unsuitable for inclusion in a community open source project. Most argued that because public domain gave them the rights they need where they live (mostly the USA), I should not say it was wrong to use it.

    That demonstrates either parochialism or a misunderstanding of what public domain really means. It should not be used for the same reason code known to be subject to software patents should not be used — namely that only code that, to the best efforts possible, can be used by anyone, anywhere without the need to ask permission (e.g. by buying a patent license) or check it it’s needed (e.g. is that PD code PD here?) can be used in an open source project. Public domain fails the test for multiple reasons: global differences in copyright term, copyright as an unalienable moral rather than as a property right, and more.

    Yes, public domain may give you the rights you need. But in an open source project, it’s not enough for you to determine you personally have the rights you need. In order to function, every user and contributor of the project needs prior confidence they can use, improve and share the code, regardless of their location or the use to which they put it. That confidence also has to extend to their colleagues, customers and community as well.

  • Introducing the Ubuntu Free Culture Showcase for 18.04

    Ubuntu’s changed a lot in the last year, and everything is leading up to a really exciting event: the release of 18.04 LTS! This next version of Ubuntu will once again offer a stable foundation for countless humans who use computers for work, play, art, relaxation, and creation. Among the various visual refreshes of Ubuntu, it’s also time to go to the community and ask for the best wallpapers. And it’s also time to look for a new video and music file that will be waiting for Ubuntu users on the install media’s Examples folder, to reassure them that their video and sound drivers are quite operational.

    Long-term support releases like Ubuntu 18.04 LTS are very important, because they are downloaded and installed ten times more often than every single interim release combined. That means that the wallpapers, video, and music that are shipped will be seen ten times more than in other releases. So artists, select your best works. Ubuntu enthusiasts, spread the word about the contest as far and wide as you can. Everyone can help make this next LTS version of Ubuntu an amazing success.

  • Retpoline Is Still Being Improved Upon For Intel Skylake/Kabylake

    While initial support for Retpoline was merged into the Linux 4.15 Git kernel last week and is now being backported to some supported Linux kernel series, there is still additional work ongoing for properly mitigating Spectre v2 on Intel Skylake CPUs and newer.

    It turns out Skylake CPUs and newer require additional patches to fully mitigate against the Spectre Variant Two vulnerability. These newer CPUs can fallback to a potentially poisoned indirect branch predictor when a return buffer underflows. Andi Kleen of Intel has sent out a new patch series dubbed "RETPOLINE_UNDERFLOW" that gets enabled by default for Skylake CPUs and newer.

  • ZAP provides automated security tests in continuous integration pipelines

    Commonly, a mixture of open source and expensive proprietary tools are shoehorned into a pipeline to perform tests on nightly as well as ad hoc builds. However, anyone who has used such tests soon realizes that the maturity of a smaller number of time-honored tests is sometimes much more valuable than the extra detail you get by shoehorning too many tests into the pipe then waiting three hours for a nightly build to complete. The maturity of your battle-hardened tests is key.

  • BitTorrent users beware: Flaw lets hackers control your computer

    There's a critical weakness in the widely used Transmission BitTorrent app that allows websites to execute malicious code on some users' computers. That's according to a researcher with Google's Project Zero vulnerability reporting team, who also warns that other BitTorrent clients are likely similarly susceptible.

    [...]

    Among the things an attacker can do is change the Torrent download directory to the user's home directory. The attacker could then command Transmission to download a Torrent called ".bashrc" which would automatically be executed the next time the user opened a bash shell. Attackers could also remotely reconfigure Transmission to run any command of their choosing after a download has completed. Ormandy said the exploit is of "relatively low complexity, which is why I'm eager to make sure everyone is patched."

    Continuous delivery (CD) is becoming the cornerstone of modern software development, enabling organizations to ship — in small increments — new features and functionality to customers faster to meet market demands. CD is achieved by applying DevOps practices and principles (continuous integration and continuous deployment) from development to operations. There is no continuous delivery without implementing DevOps practices and principles. By that, I mean strong communication and collaboration across teams, and automation across testing, build, and deployment pipelines. But often achieving continuous delivery to meet market demands presents numerous challenges for security.
