Abstract: Seccomp is an integral part of Linux sandboxes, but intimate knowledge of the required syscalls of a program are required. We present a fuzzer-based dynamic approach to auto-generate seccomp filters that permit only the required syscalls. In our model, a syscall is required, if any execution path leads to its invocation. Our implementation combines a symbolic execution step and a custom mutator to take command line flags into account and achieve a large coverage of the SUT. We provide an evaluation of our tool on popular command line tools and find up to 100% of the system calls found through manual analysis.
