Towards deductive verification of C programs with shared data

摘要

This paper considers the problem of the deductive verification of the Linux kernel code that is concurrent and accesses shared data. The presence of shared data does not allow applying traditional deductive verification techniques, so we consider how to verify such a code by proving its compliance to a given specification of a certain synchronization discipline. The approach is illustrated by the examples of a spinlock specification and a simplified specification of the read-copy-update (RCU) API.
