Fuzzing Samba

Fuzzing supplies valid, invalid, unexpected or random data as input to a piece of code. Instrumentation, usually compiler-implemented, is used to monitor for exceptions such as crashes, assertions or memory corruption.

See Wikipedia article on fuzzing for more information.

Configure with fuzzing

Example command line to build binaries for use with honggfuzz:

buildtools/bin/waf -C --without-gettext --enable-debug --enable-developer \
	--address-sanitizer --enable-libfuzzer \
	CC=.../honggfuzz/hfuzz_cc/hfuzz-clang configure \
	LINK_CC=.../honggfuzz/hfuzz_cc/hfuzz-clang

Fuzzing tiniparser

Example for fuzzing tiniparser using honggfuzz (see --help for more options):

buildtools/bin/waf --targets=fuzz_tiniparser build && \
.../honggfuzz/honggfuzz --sanitizers --timeout 3 --max_file_size 256 \
  --rlimit_rss 100 -f .../tiniparser-corpus -- bin/fuzz_tiniparser
