sys_socket_send_handle_and_data - Send a kernel object handle and data atomically

Sends a kernel object handle through a connected socket, along with data. This ensures both the handle and data are available before waking the peer, preventing race conditions in protocols like Wayland.

Arguments:

  • socket_handle: Handle to the connected socket
  • object_handle: Handle to the kernel object to send
  • data_ptr: Pointer to the data buffer
  • data_len: Length of the data buffer

Returns:

  • 0 on success
  • usize::MAX on error
