Revision 1.1 / (download) - annotate - [select for diffs], Sat Aug 1 08:40:20 2020 UTC (3 years, 10 months ago) by anton

Add support for remote coverage to kcov. Remote coverage is collected from threads other than the one currently having kcov enabled. A thread with kcov enabled occasionally delegates work to another thread, collecting coverage from such threads improves the ability of syzkaller to correlate side effects in the kernel caused by issuing a syscall. Remote coverage is divided into subsystems. The only supported subsystem right now collects coverage from scheduled tasks and timeouts on behalf of a kcov enabled thread. In order to make this work `struct task' and `struct timeout' must be extended with a new field keeping track of the process that scheduled the task/timeout. Both aforementioned structures have therefore increased with the size of a pointer on all architectures. The kernel API is documented in a new kcov_remote_register(9) manual. Remote coverage is also supported by kcov on NetBSD and Linux. ok mpi@
