+# Fuzzers
+
+These are fuzzers designed for use with `libFuzzer` or `afl`. They can
+be used to run on Google's OSS-Fuzz (https://github.com/google/oss-fuzz/).
+
+The convention used here is that the initial values for each parser fuzzer
+are taken from the $NAME.in directory.
+
+Crash reproducers from OSS-Fuzz are put into $NAME.repro directory for
+regression testing with top dir 'make check' or 'make check-valgrind'.
+
+
+# Running a fuzzer using clang
+
+Use the following commands on top dir:
+```
+export CC=clang
+# address sanitizer:
+#export CFLAGS="-O1 -g -fno-omit-frame-pointer -gline-tables-only -DFUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION -fsanitize=undefined,integer,nullability -fsanitize=address -fsanitize-address-use-after-scope -fsanitize-coverage=trace-pc-guard,trace-cmp"
+export CFLAGS="-O1 -fno-omit-frame-pointer -gline-tables-only -DFUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION -fsanitize=undefined -fsanitize=address -fsanitize-address-use-after-scope -fsanitize=fuzzer-no-link"
+# undefined sanitizer;
+export CFLAGS="-O1 -fno-omit-frame-pointer -gline-tables-only -DFUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION -fsanitize=bool,array-bounds,float-divide-by-zero,function,integer-divide-by-zero,return,shift,signed-integer-overflow,vla-bound,vptr -fno-sanitize-recover=bool,array-bounds,float-divide-by-zero,function,integer-divide-by-zero,return,shift,signed-integer-overflow,vla-bound,vptr -fsanitize=fuzzer-no-link"
+export LIB_FUZZING_ENGINE="-lFuzzer -lstdc++"
+./configure --enable-fuzzing --without-metalink --without-zlib --disable-pcre --without-libuuid --enable-assert
+make clean
+make -j$(nproc)
+cd fuzz
+
+# run wget_options_fuzzer
+UBSAN_OPTIONS=print_stacktrace=1 ASAN_SYMBOLIZER_PATH=/usr/bin/llvm-symbolizer \
+ ./run-clang.sh wget_options_fuzzer
+```
+
+If you see a crash, then a crash corpora is written that can be used for further
+investigation. E.g.
+```
+==2410==ERROR: AddressSanitizer: heap-use-after-free on address 0x602000004e90 at pc 0x00000049cf9c bp 0x7fffb5543f70 sp 0x7fffb5543720
+...
+Test unit written to ./crash-adc83b19e793491b1c6ea0fd8b46cd9f32e592fc
+```
+
+To reproduce the crash:
+```
+./wget_options_fuzzer < ./crash-adc83b19e793491b1c6ea0fd8b46cd9f32e592fc
+```
+
+You can also copy/move that file into wget_options_fuzzer.repro/
+and re-build the project without fuzzing for a valgrind run, if you like that better.
+Just a `./configure` and a `make check-valgrind` should reproduce it.
+
+
+# Running a fuzzer using AFL
+
+Use the following commands on top dir:
+
+```
+$ export LIB_FUZZING_ENGINE=""
+$ CC=afl-clang-fast ./configure --enable-fuzzing
+$ make -j$(nproc) clean all
+$ cd fuzz
+$ ./run-afl.sh wget_options_fuzzer
+```
+
+# Fuzz code coverage using the corpus directories *.in/
+
+Code coverage reports currently work best with gcc+lcov+genhtml.
+
+In the top directory:
+```
+CC=gcc CFLAGS="-O0 -g" ./configure
+make fuzz-coverage
+xdg-open lcov/index.html
+```
+
+To work on corpora for better coverage, `cd fuzz` and use e.g.
+`./view-coverage.sh wget_options_fuzzer`.
+
+
+# Creating wget_options_fuzzer.dict
+
+```
+for i in `../src/wget --help|tr ' ' '\n'|grep ^--|cut -c 3-|sort`;do echo \"$i\"; done >wget_options_fuzzer.dict
+```
