Modules

• accounting
  Coverage accounting corpus scheduler, more details at https://www.ndss-symposium.org/wp-content/uploads/2020/02/24422-paper.pdf
• ecofuzz
  The corpus scheduler from EcoFuzz (https://www.usenix.org/conference/usenixsecurity20/presentation/yue)
• minimizer
  The Minimizer schedulers are a family of corpus schedulers that feed the fuzzer with testcases only from a subset of the total corpus.
• powersched
  The queue corpus scheduler for power schedules.
• probabilistic_sampling
  Probabilistic sampling scheduler is a corpus scheduler that feeds the fuzzer with sampled item from the corpus.
• queue
  The queue corpus scheduler implements an AFL-like queue mechanism
• testcase_score
  The TestcaseScore is an evaluator providing scores of corpus items.
• tuneable
  The queue corpus scheduler implements an AFL-like queue mechanism The TuneableScheduler extends the queue scheduler with a method to chose the next corpus entry manually
• weighted
  The queue corpus scheduler with weighted queue item selection from aflpp (https://github.com/AFLplusplus/AFLplusplus/blob/1d4f1e48797c064ee71441ba555b29fc3f467983/src/afl-fuzz-queue.c#L32) This queue corpus scheduler needs calibration stage.

Structs

• RandScheduler
  Feed the fuzzer simply with a random testcase on request

Traits

• RemovableScheduler
  The scheduler also implemnts on_remove and on_replace if it implements this stage.
• Scheduler
  The scheduler define how the fuzzer requests a testcase from the corpus. It has hooks to corpus add/replace/remove to allow complex scheduling algorithms to collect data.

Type Aliases

• StdScheduler
  A StdScheduler uses the default scheduler in LibAFL to schedule Testcases. The current Std is a RandScheduler, although this may change in the future, if another Scheduler delivers better results.
