f46d7a26c1 sepolicy: rules for uid/pid cgroups v2 hierarchy
the cgroups v2 uid/gid hierarchy will replace cgroup for all sepolicy
rules. For this reason, old rules have to be duplicated to cgroup_v2,
plus some rules must be added to allow the ownership change for cgroup
files created by init and zygote.

Test: booted device, verified correct access from init, system_server
and zygote to the uid/pid cgroup files

82f7900341 Make AIDL HAL client attribute an exclusive client.
Like HIDL HALs, if we have a service which is allowed to access
hal_<foo>_service, we want that service to have the attribute
hal_<foo>_client.

Unlike HIDL HALs, some AIDL services are allowed to get ahold of all
HALs, so these have to be exempted from this check.

Test: neverallows pass

83f25e26f9 Revert "Add placeholder iris and face policy for vold data directory"
This reverts commit 92bde4b941.

Reason for revert: Rebooting after OTA fails due to the
filesystem still seeing the old label on the device.

9234e00daf hal_attribute_hwservice_client drop '_client'
Since this attribute just associates a hal_attribute
with a given hwservice in the standard way.

343e24a1be hal_attribute_hwservice_client += add_hwservice
For sanity, this makes 'hal_attribute_hwservice_client'
be associated with a specific hwservice thus making things
consistent.

After this change, only configstore, hal_allocator, and the
fwk_* services are inconsistent with all other HALs.

Bug: 80319537
Test: boot device, sanity tests, check for denials

8fc7981885 Find hal_foo_hwservice -> you are hal_foo_client.
Before, it was possible to access a hwservice without declaring
that you were a client.

This introduces the following macro:
hal_attribute_hwservice_client(hal_foo, hal_foo_hwservice)

which makes sure the above implication holds using a neverallow rule.

4d6a5e8700 Fingerprint data is now stored in one of two ways depending on the
shipping API version:

For devices shipped on O-MR1 nothing changes, data is stored
under /data/system/users/<user-id>/fpdata/...

Devices shipped from now on will instead store fingerprint data under
/data/vendor_de/<user-id>/fpdata.

Support for /data/vendor_de and /data/vendor_ce has been added to vold.

d4785c3707 Move platform/vendor data violations to device policy
Sharing data folders by path will be disallowed because it violates
the approved API between platform and vendor components tested by
VTS. Move all violating permissions from core selinux policy to
device specific policy so that we can exempt existing devices from
the ban and enforce it on new devices.

Bug: 34980020
Test: Move permissions. Build and test wifi, wifi AP, nfc, fingerprint
    and Play movies on Marlin and Taimen.
Test: build on Angler, Bullhead, Dragon, Fugu, Marlin, Walleye

This adds fine-grained policy about who can register and find which
HwBinder services in hwservicemanager.

Test: Play movie in Netflix and Google Play Movies
Test: Play video in YouTube app and YouTube web page
Test: In Google Camera app, take photo (HDR+ and conventional),
      record video (slow motion and normal), and check that photos
      look fine and videos play back with sound.
Test: Cast screen to a Google Cast device
Test: Get location fix in Google Maps
Test: Make and receive a phone call, check that sound works both ways
      and that disconnecting the call frome either end works fine.

Test: Run fast subset of media CTS tests:
      make and install CtsMediaTestCases.apk
      adb shell am instrument -e size small \
          -w 'android.media.cts/android.support.test.runner.AndroidJUnitRunner'
Test: Play music using Google Play music
Test: Adjust screen brightness via the slider in Quick Settings

      fingerprint
Test: Apply OTA update:
      Make some visible change, e.g., rename Settings app.
      make otatools && \
      make dist
      Ensure device has network connectivity
      ota_call.py -s <serial here> --file out/dist/sailfish-ota-*.zip

f98650e4ab Switch Fingerprint HAL policy to _client/_server
This switches Fingerprint HAL policy to the design which enables us to
conditionally remove unnecessary rules from domains which are clients
of Bluetooth HAL.

Domains which are clients of Fingerprint HAL, such as system_server
domain, are granted rules targeting hal_fingerprint only when the
Fingerprint 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_fingerprint are not granted to client domains.

Domains which offer a binderized implementation of Fingerprint HAL,
such as hal_fingerprint_default domain, are always granted rules
targeting hal_fingerprint.

NOTE: This commit also removes unnecessary allow rules from
Fingerprint HAL, such access to servicemanager (not hwservicemanager)
and access to keystore daemon over Binder IPC. Fingerprint HAL does
not use this functionality anyway and shouldn't use it either.

Test: Enable fingerprint + PIN secure lock screen, confirm it unlocks
      with fingerprint or PIN
Test: Disable PIN (and thus fingerprint) secure lock screen
Test: make FingerprintDialog, install, make a fake purchase
Test: Add fingerprint_hidl_hal_test to device.mk, build & add to device,
      adb shell stop,
      adb shell /data/nativetest64/fingerprint_hidl_hal_test/fingerprint_hidl_hal_test -- all tests pass
