1 kcov: code coverage for fuzzing
4 kcov exposes kernel code coverage information in a form suitable for coverage-
6 exported via the "kcov" debugfs file. Coverage collection is enabled on a task
9 Note that kcov does not aim to collect as much coverage as possible. It aims
15 kcov is also able to collect comparison operands from the instrumented code
38 program using kcov:
69 fd = open("/sys/kernel/debug/kcov", O_RDWR);
122 it needs to open /sys/kernel/debug/kcov in each thread separately.
125 That is, a parent process opens /sys/kernel/debug/kcov, enables trace mode,
157 fd = open("/sys/kernel/debug/kcov", O_RDWR);
203 Note that the kcov modes (coverage collection or comparison operands) are
