We need a mecanism for basic handling of wl_shm and wl_shm_pools. In the same fashion of the shm helpers of libwayland-server.

This raises a few questions, some of which may need support from wayland-server:

  • Be robust to a client advertizing a wrong size for the memory map (see this comment)
  • Handle resizing the memory pool (memmap crate) only supports it by unmapping and creating a new mapping)
  • Link a &WlBuffer to the underlying mapping, might need to add a user_data mechanism to wayland_server

Almost fixed by #2 I leave this open because it really needs some testing for SIGBUS robustness
