Pengutronix 2023: A Year in Review - Part I
Another exciting yet challenging year has passed. We are a year closer to the Y2038 problem, OpenSSL 1.1.1 is finally history, kernel v4.14 from 2017 will finally be discontinued in four weeks, upcoming LTS kernels will only be supported for two years. The relevance of Linux, not just in embedded systems, is soaring. Simultaneously, the European (Open Source) software world faces necessary but challenging transformations, heralded by the upcoming Cyber Resilience Act.

"FOSDEM is a free event for software developers to meet, share ideas and collaborate. Every year, thousands of developers of free and open source software from all over the world gather at the event in Brussels." -- FOSDEM
RAUC v1.5 Released
This release fixes a vulnerability in RAUC that can be exploited under certain circumstances to achieve a local privilege escalation. It provides both a mitigation for the vulnerability when using the existing bundle format as well as a new bundle format that uses dm-verity to continuously authenticate the update data while it is installed.
eMMC Hardware Partitioning
When designing an embedded system, one must consider both the application and the underlying hardware in combination, if the intended long-term stability is to be achieved. While we discussed the necessity of software updates in previous posts, in this article I describe a way to use a memory subsystem corresponding to its physics to achieve the best retention and lifetime of the whole system.
ELC-NA 2020 - A Virtual Experience
In 2020, things tend to be a bit different from what we had before. This is also true for this year's Embedded Linux Conference in North America. The need for keeping physical distance required the Linux Foundation to switch form a real conference to a fully virtual one.
Automated Testing Summit 2019
Jan, Rouven and Chris attended the Automated Testing Summit 2019 at the ELC-E in Lyon. The Summit began with Lightning Tasks on the progress in some projects. One highlight was Kevin Hilman's talk: "the bugs are too fast - and why we can't catch them."
