  • Debian Is Still Working To Land ZFS On Linux Support

    Neil McGovern has written a blog post today explaining that work is still ongoing for landing ZFS support in Debian. This ZFS file-system support will be added to Debian's contrib repository and will be a source-only, DKMS module. In other words, due to licensing issues, they will not be patching their default kernel package or the like, but rather will distribute it as a source package that will then build locally on the user's system against their installed kernel version.

  • On ZFS in Debian

    I’m currently over at FOSDEM, and have been asked by a couple of people about the state of ZFS and Debian. So, I thought I’d give a quick post to explain what Debian’s current plan is (which has come together with a lot of discussion with the FTP Masters and others around what we should do).

  • Progress report on hardened1-linux-amd64, a potential Debian port with PIE, ASAN, UBSAN and more

    Last year I started the bootstrapping during the holidays and I now have the prototype in the form of cross built packages which can be installed next to amd64 packages using multiarch.

BlueBorne Vulnerability Is Patched in All Supported Ubuntu Releases, Update Now

Canonical released today new kernel updates for all of its supported Ubuntu Linux releases, patching recently discovered security vulnerabilities, including the infamous BlueBorne that exposes billions of Bluetooth devices. The BlueBorne vulnerability (CVE-2017-1000251) appears to affect all supported Ubuntu versions, including Ubuntu 17.04 (Zesty Zapus), Ubuntu 16.04 LTS (Xenial Xerus) up to 16.04.3, Ubuntu 14.04 LTS (Trusty Tahr) up to 14.04.5, and Ubuntu 12.04 LTS (Precise Pangolin) up to 12.04.5.

Security: Updates, 2017 Linux Security Summit, Software Updates for Embedded Linux and More

  • Security updates for Tuesday
  • The 2017 Linux Security Summit
    The past Thursday and Friday was the 2017 Linux Security Summit, and once again I think it was a great success. A round of thanks to James Morris for leading the effort, the program committee for selecting a solid set of talks (we saw a big increase in submissions this year), the presenters, the attendees, the Linux Foundation, and our sponsor - thank you all! Unfortunately we don't have recordings of the talks, but I've included my notes on each of the presentations below. I've also included links to the slides, but not all of the slides were available at the time of writing; check the LSS 2017 slide archive for updates.
  • Key Considerations for Software Updates for Embedded Linux and IoT
    The Mirai botnet attack that enslaved poorly secured connected embedded devices is yet another tangible example of the importance of security before bringing your embedded devices online. A new strain of Mirai has caused network outages to about a million Deutsche Telekom customers due to poorly secured routers. Many of these embedded devices run a variant of embedded Linux; typically, the distribution size is around 16MB today. Unfortunately, the Linux kernel, although very widely used, is far from immune to critical security vulnerabilities as well. In fact, in a presentation at Linux Security Summit 2016, Kees Cook highlighted two examples of critical security vulnerabilities in the Linux kernel: one being present in kernel versions from 2.6.1 all the way to 3.15, the other from 3.4 to 3.14. He also showed that a myriad of high severity vulnerabilities are continuously being found and addressed—more than 30 in his data set.
