Instead of getting these permissions, it is better to add the process
to a group or change the permissions of the files it tries to access.
Test: Built the policy for many devices.

Current sepolicy CIL files are built by several command-line tools
in Android.mk. This change extracts some of the build logic into a
python script to relief the effort in Android.mk.
The first command is `build_sepolicy build_cil`. It's possible to add
more sub-commands under the build_sepolicy script in the future.

This change renames the non-platform sepolicy files on a DUT from
nonplat_* to vendor_*.
It also splits the versioned platform sepolicy from vendor_sepolicy.cil
to a new file /vendor/etc/selinux/plat_pub_versioned.cil. And only keeps
vendor customizations in vendor_sepolicy.cil.
Build variable BOARD_SEPOLICY_DIRS is also renamed to
BOARD_VENDOR_SEPOLICY_DIRS.

Remove bugs that have been fixed, re-map duped bugs, and alphabetize
the list.
Test: Booted Walleye and Sailfish, tested wifi and camera, and
observed no new denials.

Data outside /data/vendor must have the core_data_file_type

Data outside of /data/vendor should have the core_data_file_type.
Exempt data_between_core_and_vendor for some types.
Ensure core_data_file_type and coredomain_socket do not get expanded
to their underlying types.

test)

(cherry picked from commit bdd454792d)
This script will build the SELinux policy for multiple targets in parallel.
To use it, run:
./build_policies.sh <Android root directory> <output directory> [specific targets to build]
If you do not pass any individual targets, it will build all targets it can find.
It will print out the list of failing targets. You can open up the corresponding log file in the output directory to see the exact errors.
This script is still a work in progress. It currently cannot discover all build targets (it misses ones "lunch" does not list).
Bug: 33463570
Test: Ran script to build multiple targets with and without failures.

vendor_init exists on the system partition, but it is meant to be an
extention of init that runs with vendor permissions for executing
vendor scripts, therefore it is not meant to be in coredomain.

Instead of having statsd linking the perfetto client library
and talk directly to its socket, we let just statsd exec()
the /system/bin/perfetto cmdline client.
There are two reasons for this:
1) Simplify the interaction between statsd and perfetto, reduce
dependencies, binary size bloat and isolate faults.
2) The cmdline client also takes care of handing the trace to
Dropbox. This allows to expose the binder interaction surface
to the short-lived cmdline client and avoid to grant binder
access to the perfetto traced daemon.
This cmdline client will be used by:
- statsd
- the shell user (for our UI and Studio)

The exception for vendor_init in this neverallow was never needed.
Bug: 62875318
Test: Build walleye, bullhead

The current neverallow rules for compatible properties restrict
domains from write file permissions to the various property files.
This however is the wrong restriction, since only init actually writes
to these property files. The correct restriction is to restrict 'set'
for 'property_service' as this change does.
Note there is already a restriction preventing {domain -init} from
writing to these files in domain.te.
Test: build

We are occasionally seeing the following SELinux denial:
avc: denied { read } for comm="idmap" path="/proc/947/mounts" scontext=u:r:idmap:s0 tcontext=u:r:installd:s0 tclass=file
This commit suppresses that exact denial.
We believe this is occurring when idmap is forked from installd, which is reading its mounts file in another thread.

Since /product is an extension of /system, its file contexts should be
consistent with ones of /system.
