Linux Driver Verification
Linux driver verification is a large application area for software verification methods, in particular, for functional, safety, and security verification. Linux driver software is industrial production code — IT infrastructures rely on its stability, and thus, there are strong requirements for correctness and reliability. This implies that if a verification engineer has identified a bug in a dr...
متن کاملHow to Cook an Automated System for Linux Driver Verification
We present the preliminary results of our work on designing an automatic toolset for verification of Linux kernelspace drivers. By now the toolset includes three components: • a library of verification models; each model is a formal description of some safety property to be checked; • a preprocessor unit; it is intended for simulating an environment of a driver; • a verification unit BLAST; it ...
متن کاملIntegrated Static Analysis for Linux Device Driver Verification
We port verification techniques for device drivers from the Windows domain to Linux, combining several tools and techniques into one integrated tool-chain. Building on ideas from Microsoft’s Static Driver Verifier (SDV) project, we extend their specification language and combine its implementation with the public domain bounded model checker CBMC as a new verification back-end. We extract sever...
متن کاملDebugging the Linux Madwifi Driver
This report describes a bug in the fragmentation code of the Madwifi driver for the Atheros chipset under the Linux kernel. The bug is due to incorrect locking of a data structure. Techniques for Linux kernel debugging are described, and a fix for the bug is presented.
متن کاملPEXOR Linux device driver and DABC integration
A device driver has been developed to apply the PEXOR hardware for Linux OS. It is realized as a char driver kernel module, currently for kernel versions 2.6.27. The driver operations for read() and write() implement PIO to the PEXOR on-board memory. Operation mmap() allocates kernel buffers for DMA operations and maps these to user space addresses. The pexor kernel module manages these buffers...
