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

The original change was reverted due to InterfaceParamsTest failing.
This test has now been fixed in r.android.com/1498525.
The original change message is below.
This restriction was previously targetSdk gated for apps
with targetSdkVersion>=30.
This change is being posted for app-compat analysis and testing.

Before, we completely dissallowed any untrusted app to access a service
operated by vendor. However, sometimes this is needed in order to
implement platform APIs. So now, vendor services which aren't explicitly
marked as 'protected_service' (like protected_hwservice in HIDL) are
blocked from being used by apps. This gives everyone a mechanism for
apps to directly access vendor services, when appropriate.
For instance:
VINTF
|
vendor.img/etc | system.img/etc
|
(vendor HAL) <----AIDL---|--> (public lib <-- loaded by app
| or platform
| component)
|

This is a domain for the MediaProvider mainline module. The
MediaProvider process is responsible for managing external storage, and
as such should be able to have full read/write access to it. It also
hosts a FUSE filesystem that allows other apps to access said storage in
a safe way. Finally, it needs to call some ioctl's to set project quota
on the lower filesystem correctly.

Enforce new requirements on app with targetSdkVersion=30 including:
- No RTM_GETLINK on netlink route sockets.
Remove some of the repetitive descriptions in each untrusted_app_N.te

Only allow apps targetting < Q and ephemeral apps to open /dev/ashmem.
Ephemeral apps are not distinguishable based on target API. So allow
ephemeral_app to open /dev/ashmem for compatibility reasons.
For sake of simplicity, allow all domains /dev/ashmem permissions other
than "open". Reason being that once we can remove "open" access
everywhere, we can remove the device altogether along with other
permission.

Before this change, access to HALs from untrusted apps was prohibited
except for the whitelisted ones like the gralloc HAL, the renderscript
HAL, etc. As a result, any HAL that is added by partners can't be
accessed from apps. This sometimes is a big restriction for them when
they want to access their own HALs in the same-process HALs running in
apps. Although this is a vendor-to-vendor communication and thus is not
a Treble violation, that was not allowed because their HALs are not in
the whitelist in AOSP.
This change fixes the problem by doing the access control in the
opposite way; access to HALs are restricted only for the blacklisted
ones.
All the hwservice context that were not in the whitelist are now put
to blacklist.
This change also removes the neverallow rule for the binder access to
the halserverdomain types. This is not needed as the protected
hwservices living in the HAL processes are already not accessible; we
have a neverallow rule for preventing hwservice_manager from finding
those protected hwservices from untrusted apps.

The only distinction that matters for security is if a service is
served by vendor or not AND which process is allowed to talk to which.
coredomain is allowed to talk to vintf_service OR vendor_service, it's
just that for a non-@VintfStability service user-defined APIs (as
opposed to pingBinder/dump) are restricted.
