By using the shm file when sending the keymap to all clients, we effectively allows any client to change the keymap, as any client has the ability to change the content of the file. Sending a read-only file descriptor, or making the file itself read-only before unlinking, can be worked around by the client by using chmod(2) and open(2) on /proc/<pid>/<fd>. Using memfd could potentially solve this issue, but as the usage of mmap with MAP_SHARED is wide spread among clients, such a change can not be introduced without causing wide spread compatibility issues. So, to avoid allowing clients to interfere with each other, create a separate shm file for each wl_keyboard resource when sending the keymap. We could eventually do this per client, but in most cases, there will only be one wl_keyboard resource per client anyway. https://bugzilla.gnome.org/show_bug.cgi?id=784206 |

Mutter
Mutter is a Wayland display server and X11 window manager and compositor library.
When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.
When used on top of Xorg it acts as a X11 window manager and compositing manager.
It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.
Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork af Clutter, a scene graph and user interface toolkit.
Mutter is used by GNOME Shell, the GNOME core user interface. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.
