Test: verified proper boot in regular mode and proper working of adb in
recovery
Change-Id: Id70d27a6162af6ede94661005d80a2a780057089
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

This change limits global access to /system files down to:
/system/bin/linker*
/system/lib[64]/*
/system/etc/ld.config*
/system/etc/seccomp_policy/*
/system/etc/security/cacerts/*
/system/usr/share/zoneinfo/*

Since this attribute just associates a hal_attribute
with a given hwservice in the standard way.

Test: boot + sanity + test for denials
Change-Id: I545de165515387317e6920ce8f5e8c491f9ab24e
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
Change-Id: Ibffc65c9567a429e07a3dc4dd41117738459dc2a
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.

Commit 7688161 "hal_*_(client|server) => hal(client|server)domain"
added neverallow rules on hal_*_client attributes while simultaneously
expanding these attribute which causes them to fail CTS neverallow
tests. Remove these neverallow rules as they do not impose specific
security properties that we want to enforce.
Modify Other neverallow failures which were imposed on hal_foo
attributes and should have been enforced on hal_foo_server attributes
instead.

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.

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

Comments indicate that these permissions are used to access already
open FDs. However, getattr of a directory is clearly not necessary
for that, search of system_data_file is already granted to domain
and following symlinks is clearly not needed for reading an already
open FD.

Test: boot marlin. Test drm with google play movies, no related
denials

5/6 tests fail with no related selinux denials. The same 5/6
also fail in selinux permissive mode.

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 RsHelloCompute RenderScript demo app
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
Test: adb bugreport
Test: Enroll in fingerprint screen unlock, unlock screen using
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
Confirm the change is now live on the device

The tee domain is a vendor domain. Thus it cannot be accessed by
non-vendor components over Unix domain sockets.
It appears that the rules granting this access are not needed.
Test: Flash a clean build with this change. Confirm that bullhead,
angler, sailfish, ryu, boot without new denials.
Confirm that YouTube, Netflix, Google Play Movies play back
videos without new denials.

This switches DRM HAL policy to the design which enables us to
conditionally remove unnecessary rules from domains which are clients
of DRM HAL.
Domains which are clients of DRM HAL, such as mediadrmserver domain,
are granted rules targeting hal_drm only when the DRM 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_drm
are not granted to client domains.
Domains which offer a binderized implementation of DRM HAL, such as
hal_drm_default domain, are always granted rules targeting hal_drm.
