Functions

func GuideTowardsContainment

func GuideTowardsContainment(haystack, needle string, fakePC int)

GuideTowardsContainment instructs the libFuzzer to guide its mutations towards making haystack contain needle as a substring. fakePC serves as an ID to identify the call sites of this function.

If the relation between the raw fuzzer input and the value of haystack is relatively complex, running the fuzzer with the argument `-use_value_profile=1` may be necessary to satisfy the substring check.

func GuideTowardsEquality

func GuideTowardsEquality(s1, s2 string, fakePC int)

GuideTowardsEquality instructs the libFuzzer to guide its mutations towards making current equal to target. fakePC serves as an ID to identify the call sites of this function.

If the relation between the raw fuzzer input and the value of current is relatively complex, running the fuzzer with the argument `-use_value_profile=1` may be necessary to achieve equality.
