afl-cmin

SYNOPSIS

afl-cmin [ options ] -- /path/to/target_app [ ... ]

OPTIONS

Required parameters:


  -i dir      - input directory with the starting corpus (can be used multiple times)


  -o dir      - output directory for minimized files
Execution control settings:


  -f file     - location read by the fuzzed program (stdin)


  -m megs     - memory limit for child process (default: none)


  -t msec     - timeout for each run (default: 5000ms)


  -O          - use binary-only instrumentation (FRIDA mode)


  -Q          - use binary-only instrumentation (QEMU mode)


  -W          - use binary-only instrumentation (WINE mode)


  -U          - use unicorn-based instrumentation (Unicorn mode)


  -X          - use Nyx mode
Minimization settings:


  --crash-dir=dir - move crashes to a separate dir, always deduplicated


  -A          - allow crashes and timeouts (not recommended)


  -C          - keep crashing inputs, reject everything else


  -e          - solve for edge coverage only, ignore hit counts
Misc:


  -T workers  - number of execution and of update workers, or


                exec:update for both counts separately, or 'all'


                (default: 1)


  --as_queue  - name output files "id:000000,orig:filename", or


                "id:000000,hash:sha1" with AFL_SHA1_FILENAMES


  --no-dedup  - skip deduplication step for corpus files


  --debug     - debug mode
Metadata of an afl-fuzz output directory (fuzzer_stats, plot_data, ...)
is never used as an input, its queue/, crashes/ and hangs/ are.
Only the first 1048576 bytes of an input are given to the target.
The exit status is 0 on success and 1 on any error, including a run in
which no input matched the requested crash/timeout policy.
afl-cmin honors the 'AFL_MAP_SIZE' and 'AFL_SHA1_FILENAMES' environment variables.
