Fuzzing Rumpkernel Syscalls Part 1
It has been a great opportunity to contribute to NetBSD as a part of Google Summer Of Code '20. The aim of the project I am working on is to setup a proper environment to fuzz the rumpkernel syscalls. This is the first report on the progress made so far.
Rumpkernels provide all the necessary components to run applications on baremetal without the necessity of an operating system. Simply put it is way to run kernel code in user space.
The main goal of rumpkernels in netbsd is to run,debug,examine and develop kernel drivers as easy as possible in the user space without having to run the entire kernel but run the exact same kernel code in userspace. This makes most of the components(drivers) easily portable to different environments.
Rump Kernels are constructed out of components, So the drivers are built as libraries and these libraries are linked to an interface(some application) that makes use of the libraries(drivers). So we need not build the entire monolithic kernel just the required parts of the 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. |
