System suspend service is not a HAL, so avoid using HAL-specific macros
and attributes.
Use system_suspend_server attribute for ISystemSuspend.hal permissions.
Use system_suspend type directly for internal .aidl interface
permissions.

Apps now all share the appdomain_tmpfs type.
Bug: 122854450
Test: boot Blueline with memfd enabled.
Change-Id: I5eac0adc7ecd10d19aa1bdf5f72efc7ed2a3a548
This is being done in preparation for the migration from ashmem to
memfd. In order for tmpfs objects to be usable across the Treble
boundary, they need to be declared in public policy whereas, they're
currently all declared in private policy as part of the
tmpfs_domain() macro. Remove the type declaration from the
macro, and remove tmpfs_domain() from the init_daemon_domain() macro
to avoid having to declare the *_tmpfs types for all init launched
domains. tmpfs is mostly used by apps and the media frameworks.

internet, send text, install angry birds...play angry birds, keep

Add the required permissions for the InputClassifier HAL.

Test: no selinux denials in logcat when HAL is used inside input flinger.

1b1d133be5 added the process2 class but
forgot to suppress SELinux denials associated with these permissions
for the su domain. Suppress them.
Ensure xdp_socket is in socket_class_set, so the existing dontaudit rule
in su.te is relevant. Inspired by
66a337eec6
Add xdp_socket to various other neverallow rules.
Test: policy compiles.

system_file_type is a new attribute used to identify files which exist
on the /system partition. It's useful for allow rules in init, which are
based off of a blacklist of writable files. Additionally, it's useful
for constructing neverallow rules to prevent regressions.
Additionally, add commented out tests which enforce that all files on
the /system partition have the system_file_type attribute. These tests
will be uncommented in a future change after all the device-specific
policies are cleaned up.
Test: Device boots and no obvious problems.

* Note on cherry-pick: Some of the dependent changes are not in AOSP.
In order to keep hostapd running correctly in AOSP, I've modified this
change to only include policy additions.
Change sepolicy permissions to now classify hostapd as a HAL exposing
HIDL interface.
Sepolicy denial for accessing /data/vendor/misc/wifi/hostapd:
12-27 23:40:55.913 4952 4952 W hostapd : type=1400 audit(0.0:19): avc:

(cherry picked from commit 5bca3e860d)
The types need to be exported so userdebug system.img
can still build the policy with a user vendor.img at boot time.
All permissions and attributes for these types are still kept under
conditional userdebug_or_eng macro

Test: Boot sailfish-user build with generic_arm64_ab system.img on
sailfish and make sure sepolicy compilation succeeds

vndservicemanager is a copy of servicemanager, and so has the exact
same properties. This should be reflected in the sharing of an object
manager in SELinux policy, rather than creating a second one, which is
effectively an attempt at namespacing based on object rather than type
labels. hwservicemanager, however, provides different and additional
functionality that may be reflected in changed permissions, though they
currently map to the existing servicemanager permissions. Keep the new
hwservice_manager object manager but remove the vndservice_manager one.

hwservicemanager can check hwservice_contexts files
both from the framework and vendor partitions.
Initially, have a wildcard '*' in hwservice_contexts
that maps to a label that can be added/found from
domain. This needs to be removed when the proper policy
is in place.
Also, grant su/shell access to hwservicemanager list
operations, so tools like 'lshal' continue to work.

app_domain was split up in commit: 2e00e6373f to
enable compilation by hiding type_transition rules from public policy. These
rules need to be hidden from public policy because they describe how objects are
labeled, of which non-platform should be unaware. Instead of cutting apart the
app_domain macro, which non-platform policy may rely on for implementing new app
types, move all app_domain calls to private policy.

Test: bullhead and sailfish both boot. sediff shows no policy change.
Change-Id: I4beead8ccc9b6e13c6348da98bb575756f539665
In order to support platform changes without simultaneous updates from
non-platform components, the platform and non-platform policies must be
split. In order to provide a guarantee that policy written for
non-platform objects continues to provide the same access, all types
exposed to non-platform policy are versioned by converting them and the
policy using them into attributes.
This change performs that split, the subsequent versioning and also
generates a mapping file to glue the different policy components
together.
Test: Device boots and runs.
