Subject: [PULL 31/41] cryptodev/vhost: allocate CryptoDevBackendVhost using g_mem0()
Date: Fri, 21 Feb 2025 07:24:16 -0500 [thread overview]
Message-ID: <83cb18ac4500f3a14067b19408705068647cb0c5.1740140520.git.mst@redhat.com> (raw)
In-Reply-To: <cover.1740140520.git.mst@redhat.com>
From: Stefano Garzarella <sgarzare@redhat.com>
The function `vhost_dev_init()` expects the `struct vhost_dev`
(passed as a parameter) to be fully initialized. This is important
because some parts of the code check whether `vhost_dev->config_ops`
is NULL to determine if it has been set (e.g. later via
`vhost_dev_set_config_notifier`).
To ensure this initialization, it’s better to allocate the entire
`CryptoDevBackendVhost` structure (which includes `vhost_dev`) using
`g_mem0()`, following the same approach used for other vhost devices,
such as in `vhost_net_init()`.
Fixes: 042cea274c ("cryptodev: add vhost-user as a new cryptodev backend")
