By using libFuzzer’s 8-bit counters instead of extra counters, the coverage instrumentation in libFuzzer mode is improved in three ways: 1- 8-bit counters are supported on all platforms, including macOS and Windows, with all relevant versions of libFuzzer, whereas extra counters are a Linux-only feature that only recently received support on Windows. 2- Newly covered blocks are now properly reported as new coverage by libFuzzer, not only as new features. 3- The NeverZero strategy is used to ensure that coverage counters never become 0 again after having been positive once. This resolves issues encountered when fuzzing loops with iteration counts that are multiples of 256 (e.g., larger powers of two). |
