Linux: Detainting the Kernel, x86, and LF's Open Networking Foundation

diff -u: Detainting the Kernel
Sometimes someone submits a patch without offering a clear explanation of why the patch would be useful, and when questioned by the developers, the person offers vague or hypothetical explanations. Something like that happened recently when Matthew Garrett submitted a patch to disable a running kernel's ability to detect whether it was running entirely open-source code.
Specifically, he wanted to be able to load unsigned modules at runtime, without the kernel detecting the situation and "tainting" itself. Tainting the kernel doesn't affect its behavior in any significant way, but it is extremely useful to the kernel developers, who typically will refuse to chase bug reports on any kernel that uses closed-source software. Without a fully open-source kernel, there's no way to know that a given bug is inside the open or closed portion of the kernel. For this reason, anyone submitting bug reports to the kernel developers always should make sure to reproduce the bug on an untainted kernel.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
