Overlayfs product/overlay in init first stage is allowed in AndroidS.
product/overlay directory contains RRO apks, it is plausible to allow
dumpstate to access it since dumpstate will call df command.
Or there will be an avc denial:
01-01 07:09:37.234 13582 13582 W df : type=1400 audit(0.0:1717): avc: denied { getattr } for path="/product/overlay"
dev="overlay" ino=2 scontext=u:r:dumpstate:s0 tcontext=u:object_r:vendor_overlay_file:s0 tclass=dir permissive=0
Actually, it is more reasonable to set /product/overlay to u:object_r:system_file:s0 since
there already had definiitions releated to /product/overlay
/mnt/scratch/overlay/(system|product)/upper u:object_r:system_file:s0
/(product|system/product)/vendor_overlay/[0-9]+/.* u:object_r:vendor_file:s0

Checkin apps use /data/misc_ce/<id>/checkin to backup the checkin
metadata. So users won't lose the checkin tokens when they clear
the app's storage.
One example is when GMScore is used for checkin, users may clear
GMScore data via "settings". If the device accidentally loses the
token without backup, it won't be able to checkin again until
factory reset.
The contents in checkin dir will be cleaned up when a user is removed
from the device. We also plan to add Gmscore test to ensure the dir
is cleaned up at checkin time, thus prevent other Gmscore modules
from using this storage by mistake.

Test: boot device, check selinux label, check gmscore writes to the new dir

This adds a new property prefix owned by snapuserd, for communicating
when the service is ready to accept connections (snapuserd.ready and
snapuserd.proxy_ready).
This also adds a new socket context. This is a seqpacket socket used to
communicate with a special instance of snapuserd that bridges to the
first-stage daemon.

We ended up with 4 labels for specific APEX files that were all
identical; I've replaced them with a single one
(apex_system_server_data_file).
Additionally I created an attribute to be applied to a "standard" APEX
module data file type that establishes the basics (it can be managed
by vold_prepare_subdirs and apexd), to make it easier to add new such
types - which I'm about to do.

No longer needed now init listens for property changes on a
separate thread.
Some references to wait_for_keymaster survive: in order to avoid
trouble downstream, we keep the definition of the `wait_for_keymaster`
and `wait_for_keymaster_exec` types, but remove all their permissions,
and of course prebuilds and compat cil files are unchanged.

Metrics are written to /data/misc/odrefresh by odrefresh during early

to statsd and deletes the metrics files. This hand-off is necessary

Split gsi_metadata_file into gsi_metadata_file plus
gsi_public_metadata_file, and add gsi_metadata_file_type attribute.
Files that are okay to be publicly readable are labeled with
gsi_public_metadata_file. Right now only files needed to infer the
device fstab belong to this label.
The difference between gsi_metadata_file and gsi_public_metadata_file is
that gsi_public_metadata_file has relaxed neverallow rules, so processes
who wish to read the fstab can add the respective allow rules to their
policy files.
Allow gsid to restorecon on gsi_metadata_file to fix the file context of
gsi_public_metadata_file.

Previously we would mount OTA images with a 'context=...' mount
option. This meant that all selinux contexts were ignored in the ota
image, limiting the usefulness of selinux in this situation. To fix
this the mount has been changed to not overwrite the declared contexts
and the policies have been updated to accurately describe the actions
being performed by an OTA.
