[Xen-devel] [PATCH RFC v2 0/7] Fuzzing targets for oss-fuzz

[Wei Liu <wei.liu2@xxxxxxxxxx>]

Hi all

This series adds two fuzzing targets to run in Google's oss-fuzz
infrastructure.

There will be some other patches on the oss-fuzz side. Their recommendation is
to have all the fuzzing targets committed in our tree so that they can be
kept up to date.

The fuzzing targets aren't very sophiscated at the moment. The purpose of
this series is to gather feedback at this early stage.

We can always improve the fuzzing code in the future.

Wei.

v2:
1. Share more code between existing test code and fuzzing target.
2. More details in README.

Wei Liu (7):
  tools/fuzz: introduce libelf target
  x86emul/test: factor out emul_test_make_stack_executable
  x86emul/test: factor out emul_test_{read_cr,cpuid}
  x86emul/test: remove unused macros
  tools/fuzz: introduce x86 instruction emulator target
  tools: hook up fuzz directory
  tools/fuzz: add README
