OSS-Fuzz has been fuzzing the HTML parser with inputs up to 1 MB for
several hundred hours without hitting the 20s timeout. It seems that
most timeouts resulting from accidentally quadratic behavior in the
HTML parser have been fixed. Start to gradually reduce the timeout to
find new performance issues.
Remove the libfuzzer max_len option which doesn't apply to other
fuzzing engines. Enforce the maximum length directly in the fuzz
targets. For the xml target, lower the maximum when expanding entities
to avoid timeout and OOM errors.
- Shorten timeouts
- Align options from Makefile and options files
- Add section headers to Makefile
- Skip invalid UTF-8 in regexp fuzzer
- Update regexp.dict
- Generate HTML seed corpus in correct format
