afl-tmin
afl-tmin [ options ] -- /path/to/target_app [ ... ]
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)
Minimization settings:
-e - solve for edge coverage only, ignore hit counts
-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 milliseconds)
AFL_KILL_SIGNAL: Signal ID delivered to child processes on timeout, etc. (default: SIGKILL)
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
