Havoic find_diffs() : Logic Issue #70
Description
kafl.fuzzer/kafl_fuzzer/common/util.py
Line 89 in 4d9404d
I found dead code that return always
first_diff = 1
last_diff = min(len(data_a), len(data_b)) -1
so this code cannot find different segment A and B.
i think it need to patch like this
def find_diffs(data_a, data_b):
first_diff = 0
last_diff = 0
for i in range(min(len(data_a), len(data_b))):
if data_a[i] != data_b[i]:
if first_diff == 0:
first_diff = i
last_diff = i
