MIGRATION.md

0.14.1 -> 0.15.0

• MmapShMem::new and MmapShMemProvider::new_shmem_with_id now take AsRef<Path> instead of a byte array for the filename/id.
• The closure passed to a DumpToDiskStage now provides the Testcase instead of just the Input.
• StatsStage is deleted, and it is superceded by AflStatsStage
• Renamed and changed mapping mutators to take borrows directly instead of MappedInputs. See baby_fuzzer_custom_input for example usage
  • Related: MutVecInput is deprecated in favor of directly using &mut Vec<u8>
  • Related: MappedInputFunctionMappingMutator and ToMappedInputFunctionMappingMutatorMapper have been removed as now duplicates of MappingMutator (previously FunctionMappingMutator) and ToMappingMutator (previously ToFunctionMappingMutatorMapper)
  • Related: ToOptionMappingMutatorMapper and ToFunctionMappingMutatorMapper have been renamed to ToOptionalMutator and ToMappingMutator respectively
• Qemu cannot be used to initialize Emulator directly anymore. Instead, Qemu should be initialized through Emulator systematically if Emulator should be used.
  • Related: EmulatorBuilder uses a single function to provide a Qemu initializer: EmulatorBuilder::qemu_parameters. For now, it can be either a Vec<String> or a QemuConfig instance.
  • Related: Qemu's AsanModule does not need any special call to Qemu init methods anymore. It is now possible to simply initialize AsanModule (or AsanGuestModule) with a reference to the environment as parameter.
  • CustomBufHandlers has been deleted. Please use EventManagerHooksTuple from now on.
• Trait restrictions have been simplified
  • The UsesState and UsesInput traits have been removed in favor of regular Generics.
  • For the structs/traits that used to use UsesState, we bring back the generic for the state.
  • For UsesState, you can access to the input type through HasCorpus and Corpus traits
  • The State trait is now private in favour of individual and more specific traits
• Restrictions from certain schedulers and stages that required their inner observer to implement MapObserver have been lifted in favor of requiring Hash
  • Related: removed hash_simple from MapObserver

0.14.0 -> 0.14.1

• Removed with_observers from Executor trait.
• MmapShMemProvider::new_shmem_persistent has been removed in favour of MmapShMem::persist. You probably want to do something like this: let shmem = MmapShMemProvider::new()?.new_shmem(size)?.persist()?;

Pre 0.9 -> 0.9

• Migrating from LibAFL <0.9 to 0.9
