media: vicodec: add V4L2_CID_MIN_BUFFERS_FOR_* controls

2024-11-08T12:38:06Z

Stateful codecs must support the V4L2_CID_MIN_BUFFERS_FOR_OUTPUT and V4L2_CID_MIN_BUFFERS_FOR_CAPTURE controls. The vicodec driver was missing support for these controls. Add them. Signed-off-by: Hans Verkuil Reviewed-by: Sakari Ailus

media: v4l2-core: v4l2-dv-timings: check cvt/gtf result

2024-10-28T14:35:56Z

The v4l2_detect_cvt/gtf functions should check the result against the timing capabilities: these functions calculate the timings, so if they are out of bounds, they should be rejected. To do this, add the struct v4l2_dv_timings_cap as argument to those functions. This required updates to the adv7604 and adv7842 drivers since the prototype of these functions has now changed. The timings struct that is passed to v4l2_detect_cvt/gtf in those two drivers is filled with the timings detected by the hardware. The vivid driver was also updated, but an additional check was added: the width and height specified by VIDIOC_S_DV_TIMINGS has to match the calculated result, otherwise something went wrong. Note that vivid *emulates* hardware, so all the values passed to the v4l2_detect_cvt/gtf functions came from the timings struct that was filled by userspace and passed on to the driver via VIDIOC_S_DV_TIMINGS. So these fields can contain random data. Both the constraints check via struct v4l2_dv_timings_cap and the additional width/height check ensure that the resulting timings are sane and not messed up by the v4l2_detect_cvt/gtf calculations.

media: test-drivers: drop vb2_ops_wait_prepare/finish

2024-10-28T08:19:49Z

Since commit 88785982a19d ("media: vb2: use lock if wait_prepare/finish are NULL") it is no longer needed to set the wait_prepare/finish vb2_ops callbacks as long as the lock field in vb2_queue is set. Since the vb2_ops_wait_prepare/finish callbacks already rely on that field, we can safely drop these callbacks. This simplifies the code and this is a step towards the goal of deleting these callbacks. Signed-off-by: Hans Verkuil Reviewed-by: Shuah Khan

media: vivid: fix buffer overwrite when using > 32 buffers

2024-10-28T08:14:12Z

The maximum number of buffers that can be requested was increased to 64 for the video capture queue. But video capture used a must_blank array that was still sized for 32 (VIDEO_MAX_FRAME). This caused an out-of-bounds write when using buffer indices >= 32. Create a new define MAX_VID_CAP_BUFFERS that is used to access the must_blank array and set max_num_buffers for the video capture queue. This solves a crash reported by: https://bugzilla.kernel.org/show_bug.cgi?id=219258 Signed-off-by: Hans Verkuil Fixes: cea70ed416b4 ("media: test-drivers: vivid: Increase max supported buffers for capture queues") Cc: stable@vger.kernel.org

media: Switch back to struct platform_driver::remove()

2024-10-12T14:28:25Z

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/media to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.
