* commit '701b7d3cae0cc2546e85fcfdc706c230713a517a':
bootstat: Implement the SELinux policy to allow reading/writing to /data/misc/bootstat.
Shell user needs to be able to get current device battery_level via
/sys/class/power_supply/battery/capacity. Create a global label and
corresponding policy for accessing this. Rely on each device to label
the appropriate sysfs entry.

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.

Start labeling the directory /sys/kernel/debug/tracing. The files
in this directory need to be writable to the shell user.
Remove global debugfs:file write access. This was added in the days
before we could label individual debugfs files.

Add initial support for labeling files on /sys/kernel/debug.
The kernel support was added in https://android-review.googlesource.com/122130
but the userspace portion of the change was never completed until now.
Start labeling the file /sys/kernel/debug/tracing/trace_marker . This
is the trace_marker file, which is written to by almost all processes
in Android. Allow global write access to this file.
This change should be submitted at the same time as the system/core
commit with the same Change-Id as this patch.

Properties are now broken up from a single /dev/__properties__ file into
multiple files, one per property label. This commit provides the
mechanism to control read access to each of these files and therefore
sets of properties.
This allows full access for all domains to each of these new property
files to match the current permissions of /dev/__properties__. Future
commits will restrict the access.

Initial check in of empty autoplay_app.te policy file.
Create isAutoPlayApp input selector. Give this selector high precedence -
only below isSystemServer.
Add neverallow rule disallowing an app context with isAutoPlayApp=true from
running in a domain other than autoplay_app.

1) Don't use the generic "system_data_file" for the files in /data/nativetest.
Rather, ensure it has it's own special label. This allows us to distinguish
these files from other files in SELinux policy.
2) Allow the shell user to execute files from /data/nativetest, on
userdebug or eng builds only.
3) Add a neverallow rule (compile time assertion + CTS test) that nobody
is allowed to execute these files on user builds, and only the shell user
is allowed to execute these files on userdebug/eng builds.

Define an explicit label for /proc/sys/vm/drop_caches and grant to
the various people who need it, including vold which uses it when
performing storage benchmarks.
Also let vold create new directories under it's private storage area
where the benchmarks will be carried out. Mirror the definition of
the private storage area on expanded media.

On debuggable builds, system_server can request app heap dumps
by running something similar to the following commands:
% adb shell am set-watch-heap com.android.systemui 1048576
% adb shell dumpsys procstats --start-testing
which will dump the app's heap to /data/system/heapdump. See
framework/base commit b9a5e4ad30c9add140fd13491419ae66e947809d.
Allow this behavior.

Revert the tightening of /proc/net access. These changes
are causing a lot of denials, and I want additional time to
figure out a better solution.
Addresses the following denials (and many more):
avc: denied { read } for comm="SyncAdapterThre" name="stats" dev="proc" ino=X scontext=u:r:untrusted_app:s0:c512,c768 tcontext=u:object_r:proc_net:s0 tclass=file

Commit a833763ba0 enabled per-user
isolation, which requires that any files / processes which cross
user boundaries be marked with the mlstrustedsubject attribute.
system_app_data_file, used for storing a user's profile photos,
is not marked as such. As a result, users are unable to add profile
photos.
Addresses the following denial:
avc: denied { write } for path="/data/data/com.android.settings/cache/TakeEditUserPhoto2.jpg" dev="mmcblk0p28" ino=82184 scontext=u:r:untrusted_app:s0:c512,c768 tcontext=u:object_r:system_app_data_file:s0 tclass=file
Steps to reproduce:
1.Flash & Factory the Deb device with tip-of-tree build
2.Go to 'Settings-Users'
3.Under users&profiles,click on Owner to add profile photo.
4.Select 'Choose photo from Gallery' and select a photo.
5.Then click the 'Done' button.
6.Device showed the message as 'Unable to save the photo edits'.
OBSERVED RESULTS:
Unable to add user's profile photo id. This issue is coming for all
users(Restricted user,second user)also.
EXPECTED RESULTS:
Device should allow to add profile photo id.

external/sepolicy commit 99940d1af5
(https://android-review.googlesource.com/123331) removed /proc/net
access from domain.te.
Around the same time, system/core commit
9a20e67fa62c1e0e0080910deec4be82ebecc922
(https://android-review.googlesource.com/123531) was checked in.
This change added libnl as a dependency of libsysutils.
external/libnl/lib/utils.c has a function called get_psched_settings(),
which is annotated with __attribute__((constructor)). This code
gets executed when the library is loaded, regardless of whether or
not other libnl code is executed.
By adding the libnl dependency, even code which doesn't use the
network (such as vold and logd) ends up accessing /proc/net/psched.
For now, allow this behavior. However, in the future, it would be
better to break this dependency so the additional code isn't loaded
into processes which don't need it.
Addresses the following denials:
