NAME¶

afl-tmin

SYNOPSIS¶

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

OPTIONS¶

Required parameters:


  -i file       - input test case to be shrunk by the tool


  -o file       - final output location for the minimized data
Execution control settings:


  -f file       - input file read by the tested program (stdin)


  -t msec       - timeout for each run (1000 ms)


  -m megs       - memory limit for child process (0 MB)


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


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


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


  -W            - use qemu-based instrumentation with Wine (Wine mode)


                  (Not necessary, here for consistency with other afl-* tools)


  -X            - use Nyx mode
Minimization settings:


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


  -l bytes      - set minimum block deletion length to speed up minimization


  -x            - treat non-zero exit codes as crashes


  -H            - minimize a hang (hang mode)
For additional tips, please consult docs/README.md.
Environment variables used:
AFL_CRASH_EXITCODE: optional child exit code to be interpreted as crash
AFL_FORKSRV_INIT_TMOUT: time spent waiting for forkserver during startup (in ms)
AFL_KILL_SIGNAL: Signal ID delivered to child processes on timeout, etc.


                 (default: SIGKILL)
AFL_FORK_SERVER_KILL_SIGNAL: Kill signal for the fork server on termination


                             (default: SIGTERM). If unset and AFL_KILL_SIGNAL is


                             set, that value will be used.
AFL_MAP_SIZE: the shared memory size for that target. must be >= the size


              the target was compiled for
AFL_PRELOAD:  LD_PRELOAD / DYLD_INSERT_LIBRARIES settings for target
AFL_TMIN_EXACT: require execution paths to match for crashing inputs
AFL_NO_FORKSRV: run target via execve instead of using the forkserver
ASAN_OPTIONS: custom settings for ASAN


              (must contain abort_on_error=1 and symbolize=0)
MSAN_OPTIONS: custom settings for MSAN


              (must contain exitcode=86 and symbolize=0)
TMPDIR: directory to use for temporary input files
