When we began work to include Kata Containers with Oracle Linux Cloud Native Environment I was immediately impressed with the change they bring to the security boundary of containers but I had to wonder, how does it work? This article attempts to briefly cover the What, When and How of Kata Containers. Before we dive into Kata Containers you may want to read the brief history of Linux containers. 1. What are Kata Containers? Kata Containers is an open source [project with a]...

The latest update to Oracle Linux Cloud Native Environment introduces new functionally that we'll cover in upcoming posts but before we dive into those features, let's take a look at the history of Linux containers to see how we got here. The first fundamental building block that led to the creation of Linux containers was submitted to the Kernel by Google. It was the first version of a feature named control groups or cgroups. A cgroup is a collection of processes whose use...

In this blog post, Linux kernel developer Tom Hromatka talks about becoming a co-maintainer of libsecccomp, what it means and his recent presentation at Linux Security Summit North America 2019. Seccomp Maintainer Recently I was named a libseccomp co-maintainer. As a brief background, the Linux kernel provides a mechanism - called SECure COMPuting mode or seccomp for short - to block a process or thread's access to some syscalls. seccomp filters are written in a...

Scheduler Soft Affinity Oracle Linux kernel developer Subhra Mazumdar presents a new interface to the Linux scheduler he is proposing. Servers are getting bigger and bigger with more CPU cores, memory and I/O. This trend has lead to workload consolidation (e.g multiple virtual machines (VMs) and containers running on the same physical host). Each VM or container can run a different instance of the same or different workload. Oracle Database has a similar virtualization...
