2020-06-24Fix saturated maps & stability cliff in recalibrationDavid Melski
I have observed two problems: 1. A sudden "stability cliff" where stability drops precipitously. 2. A sudden jump to a 100% saturated "density map". Both issues are due to attempted "recalibration" of a case at the beginning of fuzz_one_original() or mopt_common_fuzzing(). See the comments "CALIBRATION (only if failed earlier on)" in those functions and the subsequent call to calibrate_case(). At those calls to calibrate_case(), afl->fsrv.trace_bits holds trace_bits for a run of the SUT on a prior queue entry. However, calibrate_case() may use the trace_bits as if they apply to the current queue entry (afl->queue_cur). Most often this bug causes the "stability cliff". Trace bits are compared for runs on distinct inputs, which can be very different. The result is a sudden drop in stability. Sometimes it leads to the "saturated map" problem. A saturated density map arises if the trace bits on the previous entry were "simplified" by simplify_trace(). Simplified traces only contain the values 1 and 128. They are meant to be compared against virgin_crashes and virgin_tmouts. However, this bug causes the (stale) simplified trace to be compared against virgin_bits during a call to has_new_bits(), which causes every byte in vigin_bits to be something other than 255. The overall map density is determined by the percentage of bytes not 255, which will be 100%. Worse, AFL++ will be unable to detect novel occurrences of edge counts 1 and 128 going forward. This patch avoids the above issues by clearing q->exec_cksum when calibration fails. Recalibrations are forced to start with a fresh trace on the queue entry. Thanks to @andreafioraldi for suggesting the current, improved patch.

2020-06-18`fault == afl->crash_mode` should be likely2019
Since during normal fuzzing, crash_mode is FSRV_RUN_OK, and fault is also usually FSRV_RUN_OK since most executions are valid executions, thus it should be likely instead of unlikely
