|
======
|
|
|
|
This directory contains fuzzer target mainly written to integrate
|
|
nghttp2 into `oss-fuzz <https://github.com/google/oss-fuzz>`_.
|
|
|
|
fuzz_target.cc contains an entry point of fuzzer. corpus directory
|
|
contains initial data for fuzzer.
|
|
|
|
The file name of initial data under corpus is the lower-cased hex
|
|
string of SHA-256 hash of its own content.
|
|
|
|
corpus/h2spec contains input data which was recorded when we ran
|
|
`h2spec <https://github.com/summerwind/h2spec>`_ against nghttpd.
|
|
|
|
corpus/nghttp contains input data which was recorded when we ran
|
|
nghttp against nghttpd with some varying command line options of
|
|
nghttp.
|
|
|
|
|
|
To build fuzz_target.cc, make sure that libnghttp2 is built with
|
|
following compiler/linker flags:
|
|
|
|
.. code-block:: text
|
|
|
|
CPPFLAGS="-fsanitize-coverage=edge -fsanitize=address"
|
|
LDFLAGS="-fsanitize-coverage=edge -fsanitize=address"
|
|
|
|
Then, fuzz_target.cc can be built using the following command:
|
|
|
|
.. code-block:: text
|
|
|
|
$ clang++ -fsanitize-coverage=edge -fsanitize=address -I../lib/includes -std=c++11 fuzz_target.cc ../lib/.libs/libnghttp2.a /usr/lib/llvm-3.9/lib/libFuzzer.a -o nghttp2_fuzzer
