This is a special profile folder where apps will leave profile markers
for the dex files they load and don't own. System server will read the
markers and decide which apk should be fully compiled instead of
profile guide compiled.
Apps need only to be able to create (touch) files in this directory.
System server needs only to be able to check wheter or not a file with a
given name exists.

Bluetooth uses the tun device for tethering. Allow access.
STEPS TO REPRODUCE:
0. Have two devices to test on, say Device A and Device B
1. On Device A, Go to settings ->Bluetooth .
2. Turn on the Bluetooth .
3. Pair it with device B
4. Tap on the paired device
OBSERVED RESULTS:
-Bluetooth share crash is observed with "Bluetooth share has stopped"
error message
-Unable to use Bluetooth tethering due to this issue
EXPECTED RESULTS:
No crash and Bluetooth devices should be able to connect for tethering
Addresses the following denial:
com.android.bluetooth: type=1400 audit(0.0:131): avc: denied { open }

Part of media security hardening
This is an intermediate step toward moving
mediadrm to a new service separate from mediaserver.
This first step allows mediadrmservice to run based
on the system property media.mediadrmservice.enable
so it can be selectively enabled on devices that
support using native_handles for secure buffers.

Access to proc is being removed but there are still some consumers. Add
an auditallow to identify them and adjust labels appropriately before
removal.

untrusted_apps could be allowed to create/unlink files in world
accessible /data locations. These applications could create
files in a way that would need cap dac_override to remove from
the system when they are uninstalled and/or leave orphaned
data behind.
Keep untrusted_app file creation to sandbox, sdcard and media
locations.

Exempt bluetooth which has net_admin capability.
Allow Droidguard to access the MAC address - droidguard runs in
priv_app domain.

No longer necessary after android.process.media moved to the
priv_app domain. Verified no new denials via audit2allow rule.

This permission was created mostly for dumpstate (so it can include
recovery files on bugreports when an OTA fails), but it was applied to
uncrypt and recovery as well (since it had a wider access before).
Grant access to cache_recovery_file where we previously granted access
to cache_file. Add auditallow rules to determine if this is really
needed.

Don't allow access to the generic debugfs label. Instead, force
relabeling to a more specific type. system_server and dumpstate
are excluded from this until I have time to fix them.
Tighten up the neverallow rules for untrusted_app. It should never
be reading any file on /sys/kernel/debug, regardless of the label.

Grant untrusted_app and isolated_app unpriv_sock_perms, neverallow
priv_sock_perms to disallow access to MAC address and ESSID.

audioserver has the same rules as mediaserver so there is
no loss of rights or permissions.
media.log moves to audioserver.
TBD: Pare down permissions.

Remove bluetooth's access to tun_device. Auditallow rule demonstrates
that it's not used.
Strengthen the neverallow on opening tun_device to include all Apps.

Motivation: Domain is overly permissive. Start removing permissions
from domain and assign them to the domain_deprecated attribute.
Domain_deprecated and domain can initially be assigned to all
domains. The goal is to not assign domain_deprecated to new domains
and to start removing domain_deprecated where it is not required or
reassigning the appropriate permissions to the inheriting domain
when necessary.
