Restrict access to Bluetooth system properties · 6e4508e6

Alex Klyubin authored 8 years ago

This removes access to Bluetooth system properties from arbitrary
SELinux domains. Access remains granted to init, bluetooth, and
system_app domains. neverallow rules / CTS enforce that access is not
granted to Zygote and processes spawned from Zygote expcept for
system_app and bluetooth.

The reason is that some of these properties may leak persistent
identifiers not resettable by the user.

Test: Bluetooth pairing and data transfer works
