2018-02-26virtio-gpu-3d: add support for second capability set (v4)Dave Airlie
Due to a kernel bug we can never increase the size of capability set 1, so introduce a new capability set in parallel, old userspace will continue to use the old set, new userspace will start using the new one when it detects a fixed kernel. v2: don't use a define from virglrenderer, just probe it. v3: fix compilation when virglrenderer disabled v4: fix style warning, just use ?: op instead.

2018-02-09Include qapi/error.h exactly where neededMarkus Armbruster
This cleanup makes the number of objects depending on qapi/error.h drop from 1910 (out of 4743) to 1612 in my "build everything" tree. While there, separate #include from file comment with a blank line, and drop a useless comment on why qemu/osdep.h is included first.

2017-02-10virtio-gpu: fix resource leak in virgl_cmd_resource_unrefGerd Hoffmann
When the guest sends VIRTIO_GPU_CMD_RESOURCE_UNREF without detaching the backing storage beforehand (VIRTIO_GPU_CMD_RESOURCE_DETACH_BACKING) we'll leak memory. This patch fixes it for 3d mode, simliar to the 2d mode fix in commit "b8e2392 virtio-gpu: call cleanup mapping function in resource destroy".

2017-01-11virtio-gpu: fix information leak in capset get dispatchLi Qiang
In virgl_cmd_get_capset function, it uses g_malloc to allocate a response struct to the guest. As the 'resp'struct hasn't been full initialized it will lead the 'resp->padding' field to the guest. Use g_malloc0 to avoid this.

2016-12-20display: virtio-gpu-3d: check virgl capabilities max_sizePrasad J Pandit
Virtio GPU device while processing 'VIRTIO_GPU_CMD_GET_CAPSET' command, retrieves the maximum capabilities size to fill in the response object. It continues to fill in capabilities even if retrieved 'max_size' is zero(0), thus resulting in OOB access. Add check to avoid it.
