CoreOS has announced the general availability of the Kubernetes container management Tectonic platform on Microsoft’s Azure cloud. The Tectonic platform enables enterprises to run Kubernetes on a single platform across various cloud and bare metal environments. Prior to this release, the Tectonic platform was available on AWS and bare metal servers. Tectonic 1.7 delivers on CoreOS’ vision to bring freedom and portability to the cloud. It enables enterprises to use a single platform to manage modern infrastructure in their hybrid environments.

In my last
article, I had some fun looking at the children’s game of rock,
paper, scissors, writing a simple simulator and finding out that some
strategies are better than others. Yes, I used “strategy” and
“rock, paper, scissors” in the same sentence!

A bug that allows an attacker to overwrite a function pointer in the kernel
opens up a relatively
easy way to compromise the kernel—doubly so, if an attacker simply
needs to wait for the kernel use the compromised pointer. There are various
techniques that can be used to protect kernel function pointers that are
set at either compile or initialization time, but there are some pointers
that are routinely set as the kernel runs; timer completion functions are a
good example. An RFC patch posted to the kernel-hardening mailing list
would add a way to detect that those function pointers have been changed
in an unexpected way and to stop the kernel from executing that code.
