The original report from Nikhil was that if data_offset > 0 and bytesused == 0, then the check in __verify_length() would fail, even though the spec says that if bytes_used == 0, then it will be replaced by the actual length of the buffer. After digging into it a bit more I realized that there were several other things wrong: - in __verify_length() it would use the application-provided length value for USERPTR and the vb2 core length for other memory models, but it should have used the application-provided length as well for DMABUF. - in __fill_vb2_buffer() on the other hand it would replace bytesused == 0 by the application-provided length, even for MMAP buffers where the length is determined by the vb2 core. - in __fill_vb2_buffer() it tries to figure out if all the planes have bytesused == 0 before it will decide to replace bytesused by length. However, the spec makes no such provision, and it makes for convoluted code. So just replace any bytesused == 0 by the proper length. The idea behind this was that you could use bytesused to signal empty planes, something that is currently not supported. But that is better done in the future by using one of the reserved fields in strucy v4l2_plane. This patch fixes all these issues. Regards, Hans Signed-off-by:
