API Reference — Implementing Fuzz Testing in CI/CD with AFL++

Libraries Used

subprocess: Execute AFL++ toolchain commands (afl-clang-fast, afl-fuzz, afl-cmin)
pathlib: File system operations for corpus and crash management

CLI Interface

python agent.py compile --source target.c --output target_fuzz [--compiler afl-clang-fast]
python agent.py fuzz --binary ./target_fuzz --input seeds/ --output findings/ [--duration 300]
python agent.py triage --binary ./target_fuzz --crashes-dir findings/default/crashes/
python agent.py stats --stats-file findings/default/fuzzer_stats

Core Functions

`compile_target(source_file, output_binary, compiler)`

Compiles target with AFL++ instrumentation. Sets AFL_HARDEN=1 for memory sanitizers.

`run_fuzzer(binary, input_dir, output_dir, duration_seconds, memory_limit)`

Runs afl-fuzz with headless mode (AFL_NO_UI=1), time-limited (-V flag).

Environment Variables Set:

Variable	Value	Purpose
`AFL_SKIP_CPUFREQ`	1	Skip CPU frequency check (CI/CD)
`AFL_NO_UI`	1	Headless mode for CI environments
`AFL_I_DONT_CARE_ABOUT_MISSING_CRASHES`	1	Continue on crash dir issues

`parse_fuzzer_stats(stats_file)`

Parses AFL++ fuzzer_stats file. Key metrics: execs_per_sec, paths_total, saved_crashes, bitmap_cvg.

`triage_crashes(binary, crashes_dir)`

Re-runs crash inputs through the binary and classifies by signal (SIGSEGV, SIGABRT, etc.).

`minimize_corpus(binary, input_dir, output_dir, timeout)`

Runs afl-cmin to remove redundant seeds from the corpus.

AFL++ Commands Used

Command	Purpose
`afl-clang-fast`	Compile with LLVM-based instrumentation
`afl-fuzz -i <in> -o <out> -- <binary>`	Main fuzzing loop
`afl-cmin -i <in> -o <out> -- <binary>`	Corpus minimization
`afl-tmin -i <crash> -o <min> -- <binary>`	Test case minimization

Dependencies

AFL++ must be installed: apt install aflplusplus or build from source.

pip install  # No Python packages needed beyond stdlib
