Deductive Verification of Unmodified Linux Kernel Library Functions
This paper presents results from the development and evaluation of a
deductive verification benchmark consisting of 26 unmodified Linux kernel
library functions implementing conventional memory and string operations. The
formal contract of the functions was extracted from their source code and was
represented in the form of preconditions and postconditions. The correctness of
23 functions was completely proved using AstraVer toolset, although success for
11 functions was achieved using 2 new specification language constructs.
Another 2 functions were proved after a minor modification of their source
code, while the final one cannot be completely proved using the existing memory
model. The benchmark can be used for the testing and evaluation of deductive
verification tools and as a starting point for verifying other parts of the
Linux kernel.Comment: 18 pages, 2 tables, 6 listings. Accepted to ISoLA 2018 conference.
