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.
With the outside world getting colder and the days becoming shorter, we at Pengutronix decided to bring a bit of light in these dark days of the year.
Now that, due to the COVID-19 pandemic, everyone has gotten used to digitalisation and online conferences - it has never been easier to organise a conference and bring together all experts and interested parties for a few hours of intensive exchange of ideas on a certain topic.
The Embedded Linux Conference Europe (ELCE) is the one biggest meetup of Embedded Linux developers in Europe. As usual Pengutronix has attended this conference - but this year from the warmth of our homes.
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.
The schedule for this year's Embedded Linux Conference Europe (ELCE) has just been released. As in the last years Pengutronix contributes talks to current topics around Embedded Linux.
It's been 3 weeks ago now since the tag for RAUC 1.4 was created. But it is vacation time and so we have a good excuse for communicating things with some delay. Fortunately, the media team is back now and so also those of you who haven't noticed the new release yet will be informed about notable changes.
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.
Here it is, commit number 1700, 291 commits after the v1.2 tag: The v1.3 release of RAUC is out in the wild and adds a lot of new and useful features together with some fixes.
