[RFC PATCH 0/8] Listening to keyboard in background, RawInput and DInput​

[Rémi Bernon]

Hi all,

I'm sending out this as follow-up of my previous e-mail [1] about dinput
and background input processing, hopefully to get some comments and to
discuss about the idea and the implementation.

The patch series also depends on some additional dinput8 patches I
already sent to the mailing list, to implement dinput8 devices on top of
raw input, but I think they can be independent.

There's a few points I believe that may be of concern, the main one
being a privacy issue. Allowing Wine applications to listen to input
while in background would allow keyloggers to work in Wine. One could
argue though that this implementation does not use any priviledged
method for that, and that Xlib allows any application to listen to raw
input events in background. I guess there may be some ways to get an
exclusive device access, to prevent other apps to get the events but
I didn't investigate this part.

Also, this is currently only used for Wine dinput8 implementation, so
we could also add some internal mechanism to enforce only Wine dinput8
to be able to access these events.
