[PATCH 0/2] fuzz: add a script to help build reproducers

Posted by Alexander Bulekov 3 years, 1 month ago

Hello,
This series adds a script that can be handy for reporting fuzzer bugs
and creating regression-tests, based on crash reproducers.

Patch 1 adds a script that can help create bash and C reproducers for
crashes.
Patch 2 documents the process of building reproducers.


Alexander Bulekov (2):
  fuzz: add a script to build reproducers
  fuzz: add instructions for building reproducers
