Due to changes in ec3705f2ed187863efc34af5415495e1ee7775d2, the app can no longer communicate with the dameon through a socket opened on the daemon side due to SELinux restrictions. The workaround here is to have the daemon decide a socket name, send it to the app, have the app create the socket server, then finally the daemon connects to the app through the socket.
