Allow goldfish-setup to put the emulator in WiFi-only mode
The goldfish-setup service (essentially /system/etc/init.goldfish.sh)
executes the following commands when certain conditions are met:
setprop ro.radio.noril yes
stop ril-daemon
so as to stop the RIL daemon and emulate a WiFi-only device. Both would
fail, though, because goldfish-setup does not have the permissions to
set relevant properties.
This CL modifies the emulator's SELinux policy to grant the necessary
permissions. It is a step towards fixing the ril-daemon-keeps-getting-
killed-and-restarted problem with the new ("ranchu") emulator, which
does not support telephony emulation yet. (The other step is to have
init start goldfish-setup, which will be done in a seperate CL.)
