Most of these fixes are small typos and tweaks. A few were caused by bad
advice from me. Here is the summary of what is changed:
- Author line edits
- Small comment changes/additions
- Using the return value in the error messages in the fuzz targets'
coder initialization code
- Removed fuzz_encode_stream.options. This set a max length, which may
prevent some worthwhile code paths from being properly exercised.
- Removed the max_len option from fuzz_decode_stream.options for the
same reason as fuzz_encode_stream. The alone decoder fuzz target still
has this restriction.
- Altered the dictionary contents for fuzz_lzma.dict. Instead of keeping
the properties static and varying the dictionary size, the properties
are varied and the dictionary size is kept small. The dictionary size
doesn't have much impact on the code paths but the properties do.
Closes: https://github.com/tukaani-project/xz/pull/73
This fuzz target handles .xz stream encoding. The first byte of input
is used to dynamically set the preset level in order to increase the
fuzz coverage of complex critical code paths.
This fuzz target that handles LZMA alone decoding. A new fuzz
dictionary .dict was also created with common LZMA header values to
help speed up the discovery of valid headers.
