media: v4l2-core: compat: ignore native command codes ...
commit 4a873f3fa5d6ca52e446d306dd7194dd86a09422 upstream.
The do_video_ioctl() compat handler converts the compat command
codes into the native ones before processing further, but this
causes problems for 32-bit user applications that pass a command
code that matches a 64-bit native number, which will then be
handled the same way.
Specifically, this breaks VIDIOC_DQEVENT_TIME from user space
applications with 64-bit time_t, as the structure layout is
the same as the native 64-bit layout on many architectures
(x86 being the notable exception).
Change the handler to use the converted command code only for
passing into the native ioctl handler, not for deciding on the
conversion, in order to make the compat behavior match the
native behavior.
Actual support for the 64-bit time_t version of VIDIOC_DQEVENT_TIME
and other commands still needs to be added in a separate patch.
