[ Upstream commit 09ca38a50795a263d2b16dc95794dc5bc17c1d5c ] If one of the controls fails to set, then 'v4l2_ctrl_request_setup' immediately returns with the error code.

media: vb2: add waiting_in_dqbuf flag

2019-05-31T13:43:12Z

commit d65842f7126aa1a87fb44b7c9980c12630ed4f33 upstream. 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 to call REQBUFS from one filehandle while the other is waiting for a buffer. This will remove all the buffers and reallocate new ones. Removing all the buffers isn't the problem here (that's already handled correctly by DQBUF), but the reallocating part is: DQBUF isn't aware that the buffers have changed. This is fixed by setting a flag whenever the lock is released while waiting for a buffer to arrive. And checking the flag where needed so we can return -EBUSY.

media: v4l2-mem2mem: Correct return type for mem2mem buffer helpers

2019-02-18T20:32:14Z

This commit changes the return type of mem2mem buffer handling API. Namely, these functions: v4l2_m2m_next_buf v4l2_m2m_last_buf v4l2_m2m_buf_remove v4l2_m2m_next_src_buf v4l2_m2m_next_dst_buf v4l2_m2m_last_src_buf v4l2_m2m_last_dst_buf v4l2_m2m_src_buf_remove v4l2_m2m_dst_buf_remove which currently return void pointer. In every case, the actual return type is a struct vb2_v4l2_buffer pointer. Change the return type of the listed functions, so type checking can be properly used.

media: vb2: keep track of timestamp status

2019-02-18T19:44:20Z

If a stream is stopped, or if a USERPTR/DMABUF buffer is queued backed by a different user address or dmabuf fd, then the timestamp should be skipped by vb2_find_timestamp since the memory it refers to is no longer valid. So keep track of a 'copied_timestamp' state: it is set when the timestamp is copied from an output to a capture buffer, and is cleared when it is no longer valid.

media: v4l2-subdev.h: v4l2_subdev_call: use temp __sd variable

2019-02-18T15:58:59Z

The sd argument of this macro can be a more complex expression. Since it is used 5 times in the macro it can be evaluated that many times as well. So assign it to a temp variable in the beginning and use that instead. This also avoids any potential side-effects of evaluating sd.

media: v4l2-mem2mem: Rename v4l2_m2m_buf_copy_data to v4l2_m2m_buf_copy_metadata

2019-02-07T17:36:33Z

The v4l2_m2m_buf_copy_data helper is used to copy the buffer metadata, such as its timestamp and its flags. Therefore, the v4l2_m2m_buf_copy_metadata name is more clear and avoids confusion with a payload data copy.
