Building Ubuntu for the Raspberry Pi

Filed under
Ubuntu

As a result of the prior musings about crowdfunding and the rather shaky VAT status of the whole sector I have been thinking quite a bit about crowdfunding and where it might be useful and how we could get involved in some way. For our normal consultancy business we have no need of capital investments and we don’t produce anything that lends itself to the crowdfunding model, however I did come up with a project I have been wanting to do for quite a long time. Allow me to introduce it by way of a little video . . .

Red Hat Patch Warning

  • We Didn't Pull CPU Microcode Update to Pass the Buck
  • Red Hat Will Revert Spectre Patches After Receiving Reports of Boot Issues
    Red Hat is releasing updates that are reverting previous patches for the Spectre vulnerability (Variant 2, aka CVE-2017-5715) after customers complained that some systems were failing to boot. "Red Hat is no longer providing microcode to address Spectre, variant 2, due to instabilities introduced that are causing customer systems to not boot," the company said yesterday. "The latest microcode_ctl and linux-firmware packages are reverting these unstable microprocessor firmware changes to versions that were known to be stable and well tested, released prior to the Spectre/Meltdown embargo lift date on Jan 3rd," Red Had added.

Security: Updates, SOS Fund, IR, ME, and WPA

  • Security updates for Friday
  • Seeking SOS Fund Projects
    I’m spending some time over the next few days looking for the next round of projects which might benefit from an SOS Fund security audit.
  • Strong Incident Response Starts with Careful Preparation
    Through working every day with organizations’ incident response (IR) teams, I am confronted with the entire spectrum of operational maturity. However, even in the companies with robust IR functions, the rapidly evolving threat landscape, constantly changing best practices, and surplus of available tools make it easy to overlook important steps during planning. As a result, by the time an incident occurs, it’s too late to improve their foundational procedures.
  • The Intel Management Engine: an attack on computer users' freedom
    Over time, Intel imposed the Management Engine on all Intel computers, removed the ability for computer users and manufacturers to disable it, and extended its control over the computer to nearly 100%. It even has access to the main computer's memory.
  • What Is WPA3, and When Will I Get It On My Wi-Fi?
    WPA2 is a security standard that governs what happens when you connect to a closed Wi-Fi network using a password. WPA2 defines the protocol a router and Wi-Fi client devices use to perform the “handshake” that allows them to securely connect and how they communicate. Unlike the original WPA standard, WPA2 requires implementation of strong AES encryption that is much more difficult to crack. This encryption ensures that a Wi-Fi access point (like a router) and a Wi-Fi client (like a laptop or phone) can communicate wirelessly without their traffic being snooped on.

First Impressions: Asus Tinkerboard and Docker

The board's standard OS is TinkerOS - a Linux variant of Debian 9. I've also read that Android is available but that doesn't interest us here. While Android may use forms of containerisation under the hood it doesn't mix with Docker containers. Rather than trying TinkerOS I flashed Armbian's release of Ubuntu 16.04.03. The stable build on the download page contains a full desktop, but if you want to run the board headless (like I do) then you can find a smaller image on the "other downloads" link. I initially used the stable image but had to swap to the nightly build due to a missing kernel module for Kubernetes networking. Having looked this up on Google I found the nightly build contained the fix to turn on the missing module. Read more
