This is a liveblog of a Black Belt track session at DockerCon EU in Copenhagen. The session is named “Container-Relevant Kernel Developments,” and the presenter is Tycho Andersen.
Andersen first presents a disclaimer that the presentation is mostly a brain dump, and the he’s not personally responsible for a lot of the work presented here. In fact, all of the work Andersen will talk about is not yet merged upstream in the Linux kernel, and he doesn’t expect that they will be accepted upstream and see availability for average users.

IMA is also responsible for allowing the Linux kernel to take advantage of a system’s Trusted Platform Module (TPM).
Pertinent to containers, Andersen talks about work that’s happening within the kernel development community around namespacing IMA. There are a number of challenges here, not all of which have been addressed or resolved yet, and Andersen refers attendees to the Linux Kernel mailing list (LKML) for more information.
Next, Andersen talks about the Linux audit log. Continue reading
