Re-exports

pub use simple::*;

pub use llmp::*;

Modules

llmp

LLMP-backed event manager for scalable multi-processed fuzzing

simple

A very simple event manager, that just supports log outputs, but no multiprocessing

Structs

EventManagerId

A per-fuzzer unique ID, usually starting with 0 and increasing by 1 in multiprocessed EventManagers, such as self::llmp::LlmpEventManager.

NopEventManager

An eventmgr for tests, and as placeholder if you really don’t need an event manager.

ShutdownSignalData

A signal handler for releasing StateRestore ShMem This struct holds a pointer to StateRestore and clean up the ShMem segment used by it.

Enums

BrokerEventResult

Indicate if an event worked or not

CustomBufEventResult

The result of a custom buf handler added using HasCustomBufHandlers::add_custom_buf_handler

Event

Events sent around in the library

EventConfig

Distinguish a fuzzer by its config

LogSeverity

The log event severity

Statics

SHUTDOWN_SIGHANDLER_DATA

Check if ctrl-c is sent with this struct

Traits

EventFirer

EventFirer fire an event.

EventManager

EventManager is the main communications hub. For the “normal” multi-processed mode, you may want to look into LlmpRestartingEventManager

EventProcessor

EventProcessor process all the incoming messages

EventRestarter

Restartable trait

HasCustomBufHandlers

Supports custom buf handlers to handle CustomBuf events.

HasEventManagerId

The id of this EventManager. For multi processed EventManagers, each connected client should have a unique ids.

ProgressReporter

ProgressReporter report progress to the broker.

Functions

shutdown_handler^⚠

Shutdown handler. SigTerm, SigInterrupt, SigQuit call this We can’t handle SIGKILL in the signal handler, this means that you shouldn’t kill your fuzzer with kill -9 because then the shmem segments are never freed

Type Definitions

ShutdownFuncPtr

Type for shutdown handler
