Subject: [PATCH] media: v4l2-core: fix VIDIOC_DQEVENT handling on non-x86
|
|
||||||
|
|
||||||
My previous bugfix addressed an API inconsistency found by syzbot,
|
|
||||||
and it correctly fixed the issue on x86-64 machines, which now behave
|
|
||||||
correctly for both native and compat tasks.
|
|
||||||
|
|
||||||
Unfortunately, John found that the patch broke compat mode on all other
|
|
||||||
architectures, as they can no longer rely on the VIDIOC_DQEVENT_TIME32
|
|
||||||
code from the native handler as a fallback in the compat code.
|
|
||||||
|
|
||||||
The best way I can see for addressing this is to generalize the
|
|
||||||
VIDIOC_DQEVENT32_TIME32 code from x86 and use that for all architectures,
|
|
||||||
leaving only the VIDIOC_DQEVENT32 variant as x86 specific. The original
|
|
||||||
code was trying to be clever and use the same conversion helper for native
|
|
||||||
32-bit code and compat mode, but that turned out to be too obscure so
|
|
||||||
even I missed that bit I had introduced myself when I made the fix.
|
|
||||||

||||||
