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

5e37271df8 Introduce system_file_type
system_file_type is a new attribute used to identify files which exist
on the /system partition. It's useful for allow rules in init, which are
based off of a blacklist of writable files. Additionally, it's useful
for constructing neverallow rules to prevent regressions.

Additionally, add commented out tests which enforce that all files on
the /system partition have the system_file_type attribute. These tests
will be uncommented in a future change after all the device-specific
policies are cleaned up.

Test: Device boots and no obvious problems.

9b2e0cbeea sepolicy: Add rules for non-init namespaces
In kernel 4.7, the capability and capability2 classes were split apart
from cap_userns and cap2_userns (see kernel commit
8e4ff6f228e4722cac74db716e308d1da33d744f). Since then, Android cannot be
run in a container with SELinux in enforcing mode.

This change applies the existing capability rules to user namespaces as
well as the root namespace so that Android running in a container
behaves the same on pre- and post-4.7 kernels.

This is essentially:
  1. New global_capability_class_set and global_capability2_class_set
     that match capability+cap_userns and capability2+cap2_userns,
     respectively.
  2. s/self:capability/self:global_capability_class_set/g
  3. s/self:capability2/self:global_capability2_class_set/g
  4. Add cap_userns and cap2_userns to the existing capability_class_set
     so that it covers all capabilities.  This set was used by several
     neverallow and dontaudit rules, and I confirmed that the new
     classes are still appropriate.

Test: diff new policy against old and confirm that all new rules add
      only cap_userns or cap2_userns;
      Boot ARC++ on a device with the 4.12 kernel.

f627e5581c restore permissions to /vendor for non-treble devices
Relabeling /vendor and /system/vendor to vendor_file removed
previously granted permissions. Restore these for non-treble devices.

Addresses:
avc: denied { execute_no_trans } for pid=2944 comm="dumpstate"
path="/system/vendor/bin/wpa_cli" dev="mmcblk0p10" ino=1929
scontext=u:r:dumpstate:s0 tcontext=u:object_r:vendor_file:s0
tclass=file

And potentially some other bugs that have yet to surface.

1625dba935 remove setuid SELinux capability for racoon.
In the master external/ipsec-tools/{main.c, racoon.rc},
racoon doesn't call setuid, and doesn't have the setuid capability.

cc39f63773 Split general policy into public and private components.
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.
