Add `virtio-blk` fuzzing target

00xc commented 1 year ago

Add a new cargo-fuzz target to test virtio-blk request parsing. Add as well a simple test.

This new target mimics the existing virtio-vsock one in a much simpler way, as the virtio-blk interface is smaller.

Increased coverage by using the backend-stdio feature of the crate with a backing memfd file. Also rebased from main.

Crashes in the CI still happen, will be fixed with #253.

Rebased on main and simplified the harness removing useless functionality.
