Environment Modeling of Linux Operating System Device Drivers

Generating environment model for Linux device drivers

Linux device drivers can't be analyzed separately from the kernel core due to their large interdependency with each other. But source code of the whole Linux kernel is rather complex and huge to be analyzed by existing model checking tools. So a driver should be analyzed with environment model instead of the real kernel core. In the given paper requirements for driver environment model are disc...

Standalone Device Drivers in Linux

However, this traditional scheme has a number of major disadvantages. First of all, it means that each version of the device driver is linked to a specific version of the kernel. So if a device is only supported in a development release, a customer who might otherwise want to use a stable, production release might be forced to use a bleeding-edge system. Alternatively, there may be bugs present...

Tolerating Malicious Device Drivers in Linux

This paper presents SUD, a system for running existing Linux device drivers as untrusted user-space processes. Even if the device driver is controlled by a malicious adversary, it cannot compromise the rest of the system. One significant challenge of fully isolating a driver is to confine the actions of its hardware device. SUD relies on IOMMU hardware, PCI express bridges, and messagesignaled ...

Reuse Linux Device Drivers in Embedded Systems

Device driver is one component that is usually ignored by research community in operating systems. Their design mechanisms, accessing semantics, operating behaviors and runtime performance are crucial to operating system architecture and total system performance. In this paper, an I/O package to reuse Linux device drivers in embedded system is introduced. Via this package, the whole Linux devic...
