Experiment with bedrock #269

Description

@morehouse

@dergoegge shared some patches that allow smite to work with the bedrock hypervisor:

The main benefits:

  • 100% determinism and stability (modulo some bugs), which would likely improve our fuzzing efficiency significantly
  • bedrock is currently maintained, unlike Nyx
  • skips idle time
  • causes unusual thread-schedules, which can uncover certain bugs more easily

Main downsides:

  • special hardware and kernel requirements
  • not thoroughly tested; alpha quality

@dergoegge also mentioned that we may be able to avoid AFL++ patches by adding the Nyx hooks to bedrock so that AFL++ doesn't know the difference.
