This commit fixes configuration of the pooling instance allocator when traps are disallowed while fuzzing to ensure that there's at least one page of memory. The support in `wasm-smith` currently forcibly creates a 1-page memory which was previously invalid in the pooling instance allocator under the generated configuration, so this commit updates the configuration generated to ensure that it can fit the generated module.
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.
