Hi Shuah, Mauro,
I noticed that the function vb2_core_streamon() in videobuf2-core.c calls
v4l_vb2q_enable_media_source(q).
That function in turn assumes that q->owner is a v4l2_fh struct. But I
don't think that is true for DVB devices.
And since videobuf2-core.c is expected to be DVB/V4L indepe
Calling VIDIOC_DQBUF can release the core serialization lock pointed to
by vb2_queue->lock if it has to wait for a new buffer to arrive.
However, if userspace dup()ped the video device filehandle, then it is
possible to read or call DQBUF from two filehandles at the same time.
It is also possible
If queue->lock is different from the video_device lock, then
you need to serialize queue_setup with VIDIOC_S_FMT, and this
should be done by the driver.

These four patches fix syzkaller race conditions. The first patch

Trace points are much more efficient than debug messages for intensive
tracing and could be conveniently enabled / disabled dynamically, hence
let's replace debug messages with the trace points. This also makes

Here's a new version of the Rockchip VPU JPEG encoder driver,
for the RK3288 and RK3399 SoCs.
This new version supports V4L2_PIX_FMT_JPEG capture format,
which means standard userspace can be used, such as gstreamer:
gst-launch-1.0 videotestsrc ! v4l2jpegenc
extra-controls="c,compression_quali
Userspace shouldn't set bytesused to 0 for output buffers.
vb2_warn_zero_bytesused() warns about this (only once!), but it also
calls WARN_ON(1), which is confusing since it is not immediately clear
that it warns about a 0 value for bytesused.
Just drop the WARN_ON as it serves no purpose.
