[PATCH v2 0/4] Miscellaneous fuzzer changes

Posted by Alexander Bulekov 2 years, 10 months ago

v2:
    - Add the instrumentation filter to the instrumentation filter patch

These patches
1.) Change generic-fuzzer timeouts so they are reconfigured prior to
each individual IO command, to allow for longer-running inputs
2.) Add an instrumentation filter to prevent libfuzzer from tracking
noisy/irrelevant parts of the code.
3.) Fix the AC97 and ES1370 fuzzer configs

Alexander Bulekov (4):
  fuzz: adjust timeout to allow for longer inputs
  fuzz: add an instrumentation filter
  fuzz: fix the AC97 generic-fuzzer config.
  fuzz: fix the ES1370 generic-fuzzer config.
