From bc3d27234ed90924ae200a916afb97d1945912d5 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Tue, 11 Jan 2022 22:23:25 +0200 Subject: v4l2: v4l2_camera_proxy: Zero flags in VIDIOC_REQBUFS The V4L2 compatibility layer doesn't support any of the VIDIOC_REQBUFS flags. They are all correctly ignored, but also need to be zeroed before returning to indicate that they haven't been taken into account. This fixes a v4l2-compliance failure: Buffer ioctls (Input 0): fail: ../../utils/v4l2-compliance/v4l2-test-buffers.cpp(682): coherent test VIDIOC_REQBUFS/CREATE_BUFS/QUERYBUF: FAIL Fixes: aa4533639971 ("include: linux: Update kernel headers to version v5.16-rc7") Signed-off-by: Laurent Pinchart Tested-by: Vedant Paranjape Reviewed-by: Paul Elder --- src/v4l2/v4l2_camera_proxy.cpp | 1 + 1 file changed, 1 insertion(+) (limited to 'src/v4l2/v4l2_camera_proxy.cpp') diff --git a/src/v4l2/v4l2_camera_proxy.cpp b/src/v4l2/v4l2_camera_proxy.cpp index 4d529bc2..1802d90b 100644 --- a/src/v4l2/v4l2_camera_proxy.cpp +++ b/src/v4l2/v4l2_camera_proxy.cpp @@ -469,6 +469,7 @@ int V4L2CameraProxy::vidioc_reqbufs(V4L2CameraFile *file, struct v4l2_requestbuf return -EBUSY; arg->capabilities = V4L2_BUF_CAP_SUPPORTS_MMAP; + arg->flags = 0; memset(arg->reserved, 0, sizeof(arg->reserved)); if (arg->count == 0) { -- cgit v1.2.1
