Moving Linux Kernel Drivers To User-Space? Nope.
Brought up on the Linux kernel mailing list this week was a short-lived discussion whether Linux device drivers should be moved from kernel-space to user-space in an attempt to provide "greater security and robustness" of Linux systems.
Jidong Xiao asked on Wednesday, Can we move device drivers into user-space? It's been a matter that's been brought up before in past years and he cited an earlier research paper on "Tolerating Malicious Device Drivers in Linux." Jidong's reasoning for bringing up the topic again is that, "Advantage: Since most of kernel bugs are caused by device drivers issues, moving device drivers into user space can reduce the impact of device driver bugs. From security perspective, the system can be more secure and robust if most device drivers are working in user space. Disadvantage: At least, existing techniques as well as the above paper showed a relatively high overhead."

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. |
