For example, the `controls` field in the `virtio_snd_config` structure is optional and should only be included in the configuration size if the `VIRTIO_SND_F_CTLS` feature has been negotiated. - -This issue became apparent after commit `ab0c7fb2`, where `virtio_snd_config` was updated to include the `controls` field. The vhost-user-snd frontend, relying on this structure, started expecting `sizeof(virtio_snd_config)` when communicating with the backend, regardless of whether the `VIRTIO_SND_F_CTLS` feature was negotiated. As a result, any backend reporting a smaller configuration size—for example, one that does not support controls—cannot communicate with the frontend. We observed this problem in the vhost-device-sound rust-vmm device, which we partially fixed [here](https://github.com/rust-vmm/vhost-device/commit/8e7b7109316e1027548bc91cfcbb4b096b032c24). - -This behavior is incorrect because the configuration size should depend on the negotiated features. - -I am currently working on patch to fix this.""" -reproduce = """1.
