VR HWC is being split out of VR Window Manager. It creates a HW binder
interface used by SurfaceFlinger which implements the HWComposer HAL and
a regular binder interface which will be used by a system app to receive
the SurfaceFlinger output.

This switches most remaining HALs to the _client/_server approach.
To unblock efforts blocked on majority of HALs having to use this
model, this change does not remove unnecessary rules from clients of
these HALs. That work will be performed in follow-up commits. This
commit only adds allow rules and thus does not break existing
functionality.

The HALs not yet on the _client/_server model after this commit are:
* Allocator HAL, because it's non-trivial to declare all apps except
  isolated apps as clients of this HAL, which they are.
* Boot HAL, because it's still on the non-attributized model and I'm
  waiting for update_engine folks to answer a couple of questions
  which will let me refactor the policy of this HAL.

This switches Dumpstate HAL policy to the design which enables us to
conditionally remove unnecessary rules from domains which are clients
of Dumpstate HAL.

Domains which are clients of Dumpstate HAL, such as dumpstate domain,
are granted rules targeting hal_dumpstate only when the Dumpstate HAL
runs in passthrough mode (i.e., inside the client's process). When the
HAL runs in binderized mode (i.e., in another process/domain, with
clients talking to the HAL over HwBinder IPC), rules targeting
hal_dumpstate are not granted to client domains.

Domains which offer a binderized implementation of Dumpstate HAL, such
as hal_dumpstate_default domain, are always granted rules targeting
hal_dumpstate.

Create an event_log_tags_file label and use it for
/dev/event-log-tags.  Only trusted system log readers are allowed
direct read access to this file, no write access.  Untrusted domain
requests lack direct access, and are thus checked for credentials via
the "plan b" long path socket to the event log tag service.

Introduce the add_service() macro which wraps up add/find
permissions for the source domain with a neverallow preventing
others from adding it. Only a particular domain should
add a particular service.

Use the add_service() macro to automatically add a neverallow
that prevents other domains from adding the service.

mediadrmserver was adding services labeled mediaserver_service.
Drop the add permission as it should just need the find
permission.

Additionally, the macro adds the { add find } permission which
causes some existing neverallow's to assert. Adjust those
neverallow's so "self" can always find.

Test: compile and run on hikey and emulator. No new denials were
found, and all services, where applicable, seem to be running OK.

This restricts access to ro.serialno and ro.boot.serialno, the two
system properties which contain the device's serial number, to a
select few SELinux domains which need the access. In particular, this
removes access to these properties from Android apps. Apps can access
the serial number via the public android.os.Build API. System
properties are not public API for apps.

The reason for the restriction is that serial number is a globally
unique identifier which cannot be reset by the user. Thus, it can be
used as a super-cookie by apps. Apps need to wean themselves off of
identifiers not resettable by the user.

Test: Set up fresh GMS device, install some apps via Play, update some apps, use Chrome
Test: Access the device via ADB (ADBD exposes serial number)
Test: Enable MTP over USB, use mtp-detect to confirm that serial number is reported in MTP DeviceInfo

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.

Divide policy into public and private components.  This is the first
step in splitting the policy creation for platform and non-platform
policies.  The policy in the public directory will be exported for use
in non-platform policy creation.  Backwards compatibility with it will
be achieved by converting the exported policy into attribute-based
policy when included as part of the non-platform policy and a mapping
file will be maintained to be included with the platform policy that
maps exported attributes of previous versions to the current platform
version.

Eventually we would like to create a clear interface between the
platform and non-platform device components so that the exported policy,
and the need for attributes is minimal.  For now, almost all types and
avrules are left in public.

Test: Tested by building policy and running on device.

This fixes the build error:

=====
libsepol.report_assertion_extended_permissions: neverallowxperm on line 166 of system/sepolicy/domain.te (or line 9201 of policy.conf) violated by
allow dumpstate dumpstate:netlink_tcpdiag_socket { ioctl };
libsepol.check_assertions: 1 neverallow failures occurred
=====

Which is caused, in AOSP and downstream branches, by

Test: builds.

Currently, we define 4 hardcoded init services to launch dumpstate with
different command-line options (since dumpstate must be launched by
root):

- bugreport
- bugreportplus
- bugreportwear
- bugreportremote

This approach does not scale well; a better option is to have just one
service, and let the framework pass the extra arguments through a system
property.

These APIs expose sensitive information via timing side channels. This
leaves access via the adb shell intact along with the current uses by
dumpstate, init and system_server.

The /proc/interrupts and /proc/stat files were covered in this paper:

https://www.lightbluetouchpaper.org/2016/07/29/yet-another-android-side-channel/

The /proc/softirqs, /proc/timer_list and /proc/timer_stats files are
also relevant.

Access to /proc has been greatly restricted since then, with untrusted
apps no longer having direct access to these, but stricter restrictions
beyond that would be quite useful.
