It's beneficial to be able to overide this in a device makefile
if you need to get the domains into an unconfined state to keep
the logs from filling up on kernel entries without having to add
rules into device specific policy.

This seems to not really being used, especially considering
that the init.rc does not have a oneshot service for it, and its
not using the build_policy() and other things to even make it
configurable.

Recovery should never be accessing files from /data.
In particular, /data may be encrypted, and the files within
/data will be inaccessible to recovery, because recovery doesn't
know the decryption key.
Enforce write/execute restrictions on recovery. We can't tighten
it up further because domain.te contains some /data read-only
access rules, which shouldn't apply to recovery but do.
Create neverallow_macros, used for storing permission macros
useful for neverallow rules. Standardize recovery.te and
property_data_file on the new macros.

Force any experimental SELinux domains (ones tagged with
"permissive_or_unconfined") into unconfined. This flag is
intended to be flipped when we're preparing a release,
to eliminate inconsistencies between user and userdebug devices,
and to ensure that we're enforcing a minimal set of rules for all
SELinux domains.
Without this change, our user builds will behave differently than
userdebug builds, complicating testing.

Add a service_mananger class with the verb add.
Add a type that groups the services for each of the
processes that is allowed to start services in service.te
and an attribute for all services controlled by the service
manager. Add the service_contexts file which maps service
name to target label.

The selinux_version file is used to perform policy
versioning checks by libselinux and SELinuxMMAC. When
loading policy a check is first performed to determine
if the policy out in /data/security/current should be
used to override the base policy shipped with the device.
The selinux_version file is used to make that choice. The
contents of the file simply contains the BUILD_FINGERPRINT
that the policy was built against. A simple string comparison
is then performed by libselinux and SELinuxMMAC.

Permissive domains are only intended for development.
When a device launches, we want to ensure that all
permissive domains are in, at a minimum, unconfined+enforcing.
Add FORCE_PERMISSIVE_TO_UNCONFINED to Android.mk. During
development, this flag is false, and permissive domains
are allowed. When SELinux new feature development has been
frozen immediately before release, this flag will be flipped
to true. Any previously permissive domains will move into
unconfined+enforcing.
This will ensure that all SELinux domains have at least a
minimal level of protection.
Unconditionally enable this flag for all user builds.

In 9af6f1bd59, the -d option
was dropped from insertkeys.py. This was done to allow an
Android distribution to replace the default version of
keys.conf distributed in external/sepolicy/keys.conf. keys.conf
was modified to reference the publicly known test keys in
build/target/product/security.
Unfortunately, this broke Google's build of Android. Instead
of incorporating our keys directory, we were using the
default AOSP keys. As a result, apps were getting assigned
to the wrong SELinux domain. (see "Steps to reproduce" below)
This change continues to allow others to replace keys.conf,
but makes DEFAULT_SYSTEM_DEV_CERTIFICATE available as an
environment variable in case the customized version wants to
make reference to it. This change also modifies the stock
version of keys.conf to use DEFAULT_SYSTEM_DEV_CERTIFICATE,
which should be appropriate for most Android distributions.
It doesn't make any sense to force each OEM to have a copy of
this file.
Steps to reproduce.
1) Compile and boot Android.
2) Run the following command: "adb shell ps -Z | grep process.media"
Expected:
$ adb shell ps -Z | grep process.media
u:r:media_app:s0 u0_a5 1332 202 android.process.media
Actual:
$ adb shell ps -Z | grep process.media
u:r:untrusted_app:s0 u0_a5 3617 187 android.process.media

This breaks the ability for users to have certs in many
directories. Currently the design is to allow keys.conf
to specify arbitrary locations for pem files, relative to
the root of the Android tree. If users want to have a
common prefix on all the keys, then they can export
DEFAULT_SYSTEM_DEV_CERTIFICATE, and make that an environment
variable in their keys.conf file.

This is a rewrite of the existing implementation.
Three new variables are now needed to add/modify
the exisitng base policy. They are, BOARD_SEPOLICY_REPLACE
and BOARD_SEPOLICY_UNION which govern what files
are replaced and concatenated, and BOARD_SEPOLICY_DIRS
which lists the various directories that will contain
the BOARD_SEPOLICY_REPLACE and BOARD_SEPOLICY_UNION
policy files.

"sepolicy" is a phony target defined by the build system.
If you use it as dependency of a file target, you'll get unnecessary
