Microkernels and Component-based OS

Linux Kernel Library

A Library Version of Linux Kernel
K.4.601
Hajime Tazaki
LKL (Linux Kernel Library) is aiming to allow reusing the Linux kernel code as extensively as possible with minimal effort and reduced maintenance overhead. It allows us to link the library with any programs (which wish to call as a function call) containing Linux kernel code. There are many use cases: reading/writing files without general system calls, putting experimental protocol implementation without neither of host kernel update nor kernel module installation, using customized kernel in container instance, building a unikernel based on existing rumprun framework, or testing/fuzzing kernel implementation in userspace execution, etc. In this talk, we are going to present why/how/when we started this project, share the outcomes using LKL fuzzing test with Linux filesystem out of tree network protocols on Android lkl.js macOS port docker integration future directions including upstreaming to Linux kernel

I will give an overview of where seL4 stands today in terms of functionality, verification, ecosystem, deployment and community. The focus will be on what has happened in seL4 land over the past 12 months, which is a lot: seL4 Foundation, RISC-V support and introducing time protection.

Current microkernels have shown to provide advantages in terms of security, robustness, and flexibility of systems. However, in recent years, the hardware added new challenges that need to be addressed as well, demanding approaches that include the hardware into the picture. First, hardware is getting more and more heterogeneous and consists not only of general-purpose cores, but contains also various accelerators. Second, system designers need to integrate untrusted third-party components ...

Phantom OS is an Operating system based on the orthogonal persistence. Application does not feel OS shutdown and restart. Even abrupt restart. It is guaranteed that application will be restarted in consistent state.

Gneiss is an abstraction layer for component based environments that aims to provide a foundation for formally provable components. It enables the creation of platform independent, asynchronous components in SPARK and provides function contracts that allow to prove the correct interaction with the underlying platform.

With 2.5 billions of active users Android is the most widely deployed mobile operating system in the world. Its vast complexity paired with a monolithic architecture regularly result in severe security issues like the infamous Stagefright bug. In this presentation we talk about an ongoing research project which aims at running Android applications on top of the component-based Genode OS framework and secure them using formally verified components. We discuss how Android applications interact, ...

Sculpt OS is a novel general-purpose operating system designed from the ground up and implemented using the building blocks of the Genode OS framework. It started with the vision of a truly trustworthy OS that combines a completely new system structure with microkernels, capability-based security, sandboxed device drivers, and virtual machines. The talk is a live demonstration of the current incarnation of Sculpt.
