Avinux: Towards Automatic Verification of Linux Device Drivers

Avinux is a tool that facilitates the automatic analysis of Linux and especially of Linux device drivers. The tool is implemented as a plugin for the Eclipse IDE, using the source code bounded model checker CBMC as its backend. Avinux supports a verification process for Linux that includes specification annotation in SLICx (an extension of the SLIC language), automatic data environment creation, source code transformation and simplification, and the invocation of the verification backend. We have successfully used Avinux for the automatic analysis of Linux device drivers reducing the immense overhead of manual code preprocessing that other projects incurred.
