media: vivid: use vfree() instead of kfree() for dev->bitmap_cap

2019-05-31T13:43:12Z

commit dad7e270ba712ba1c99cd2d91018af6044447a06 upstream. syzkaller reported crashes on kfree() called from vivid_vid_cap_s_selection(). This looks like a simple typo, as dev->bitmap_cap is allocated with vzalloc() throughout the file.

media: vivid: Add definitions for the 32-bit packed YUV formats

2019-02-18T19:32:42Z

Enable vivid to make use of the following formats: V4L2_PIX_FMT_AYUV32 V4L2_PIX_FMT_XYUV32 V4L2_PIX_FMT_VUYA32 V4L2_PIX_FMT_VUYX32 Signed-off-by: Vivek Kasireddy Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: vivid: two unregistration fixes

2019-02-18T17:31:58Z

When the media device registration fails, don't call media_device_unregister since the device was never actually registered. When removing the module also call media_device_cleanup() to avoid a memory leak. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: vivid: add vertical down sampling to imagesize calc

2019-02-07T17:24:03Z

To correctly set the size of the image in a plane, it's needed to divide the height of image by the vertical down sampling factor. This was only happening in vivid_try_fmt_vid_cap(), but now it applied in others sizeimage calculations as well.

media: vivid: fix vid_out_buf_prepare()

2019-01-31T11:32:05Z

The wrong size check was performed for output formats like NV24 which set vfmt->buffers to 1, but vfmt->planes is 2. It was incorrectly checking the payload size for plane 1, which doesn't exist. Note: vfmt->buffers refers to the number of per-plane-buffers that should be allocated. vfmt->planes refers to the number of planes that make up an image. vfmt->planes may be > vfmt->buffers.

media: vivid: add buf_out_validate callback

2019-01-31T11:30:38Z

Validate the field for an output buffer. This ensures that the field is validated when the buffer is queued to a request, and not when the request itself is queued, which is too late. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: vivid: do not implement VIDIOC_S_PARM for output streams

2019-01-16T18:43:16Z

v4l2_compliance gave a warning for the S_PARM test for output streams: warn: v4l2-test-formats.cpp(1235): S_PARM is supported for buftype 2, but not for ENUM_FRAMEINTERVALS The reason is that vivid mapped s_parm for output streams to g_parm. But if S_PARM doesn't actually change anything, then it shouldn't be enabled at all. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: vivid: take data_offset into account for video output

2019-01-16T18:40:49Z

The video output sizeimage calculation did not take data_offset into account. This can cause problems with video loopback or exporting output buffers for use as dmabuf import buffers since the output buffer size is now too small. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: vivid: disable VB2_USERPTR if dma_contig was configured

2019-01-16T18:36:42Z

It makes no sense to support the USERPTR memory model if the vivid instance was configured as dma_contig. Disable it if this is the case. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
