Module libafl::feedbacks

The feedbacks reduce observer state after each run to a single is_interesting-value. If a testcase is interesting, it may be added to a Corpus.

Re-exports

pub use map::*;

Modules

map	Map feedback, maximizing or minimizing maps, for example the afl-style map observer.

Structs

CombinedFeedback
CrashFeedback	A CrashFeedback reports as interesting if the target crashed.
LogicEagerAnd
LogicEagerOr
LogicFastAnd
LogicFastOr
NotFeedback	Compose feedbacks with an OR operation
TimeFeedback	Nop feedback that annotates execution time in the new testcase, if any for this Feedback, the testcase is never interesting (use with an OR) It decides, if the given TimeObserver value of a run is interesting.
TimeoutFeedback	A TimeoutFeedback reduces the timeout value of a run.

Traits

Feedback	Feedbacks evaluate the observers. Basically, they reduce the information provided by an observer to a value, indicating the “interestingness” of the last run.
FeedbackLogic
FeedbackState	FeedbackState is the data associated with a Feedback that must persist as part of the fuzzer State
FeedbackStatesTuple	A haskell-style tuple of feedback states

Type Definitions

EagerAndFeedback	Combine two feedbacks with an eager AND operation, will call all feedbacks functions even if not necessery to conclude the result
EagerOrFeedback	Combine two feedbacks with an eager OR operation, will call all feedbacks functions even if not necessery to conclude the result
FastAndFeedback	Combine two feedbacks with an fast AND operation, might skip calling feedbacks functions if not necessery to conclude the result
FastOrFeedback	Combine two feedbacks with an fast OR operation, might skip calling feedbacks functions if not necessery to conclude the result This means any feedback that is not first might be skipped, use caution when using with TimeFeedback
