* Enable copy-on-write heap initialization by default This commit enables the `Config::memfd` feature by default now that it's been fuzzed for a few weeks on oss-fuzz, and will continue to be fuzzed leading up to the next release of Wasmtime in early March. The documentation of the `Config` option has been updated as well as adding a CLI flag to disable the feature. * Remove ubiquitous "memfd" terminology Switch instead to forms of "memory image" or "cow" or some combination thereof. * Update new option names
Fuzzing Infrastructure for Wasmtime
This crate provides test case generators and oracles for use with fuzzing.
These generators and oracles are generally independent of the fuzzing engine
that might be using them and driving the whole fuzzing process (e.g. libFuzzer
or AFL). As such, this crate does not contain any actual fuzz targets
itself. Those are generally just a couple lines of glue code that plug raw input
from (for example) libFuzzer into a generator, and then run one or more
oracles on the generated test case.
If you're looking for the actual fuzz target definitions we currently have, they
live in wasmtime/fuzz/fuzz_targets/* and are driven by cargo fuzz and
libFuzzer.
