Added a new check to make sure that all listed
BOARD_SEPOLICY_UNION files are located somewhere
in the listed BOARD_SEPOLICY_DIRS locations. The
build will error out otherwise.

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.

Create a new m4 macro called userdebug_or_eng. Arguments
passed to this macro are only emitted if we're performing
a userdebug or eng build.
Merge shell.te and shell_user.te and eliminate duplicate
lines. Same for su.te and su_user.te
Change-Id: I8fbabca65ec392aeafd5b90cef57b5066033fad0
Also make su and shell permissive in non-user builds to allow
use of setenforce without violating the neverallow rule.

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.

Increase the SELinux policy version to 26. This is needed

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
rebuild.

The policy version suffix support was carried over from conventional
Linux distributions, where we needed to support simultaneous installation
of multiple kernels and policies. This isn't required for Android, so
get rid of it and thereby simplify the policy pathname.
We still default to generating a specific policy version (the highest
one supported by the emulator kernel), but this can be overridden
by setting POLICYVERS on the make command-line or in the environment.
Requires a corresponding change to libselinux.

* commit '10f9a3727a5c46ef23f5f0385ae4ffec20cb46d9':
Corrected gramatical issues
Added new line to end of file
Changed seapp_contexts temporary file naming
Fix mls checking code
Support overrides in seapp_contexts
Add tf_daemon labeling support.
Add ppp/mtp policy.
per device seapp_context support
dhcp policy.
Trusted Execution Environment policy.
ocontexts was split up into 4 files:
1.fs_use
2.genfs_contexts
3.initial_sid_contexts
4.port_contexts
Each file has their respective declerations in them.
Devices, in their respective device directory, can now specify sepolicy.fs_use, sepolicy.genfs_contexts, sepolicy.port_contexts, and sepolicy.initial_sid_contexts. These declerations will be added right behind their respective sepolicy counterparts in the concatenated configuration file.
New property_contexts file for property selabel backend.
New property.te file with property type declarations.
New property_service security class and set permission.
Allow rules for setting properties.
Avoid any future collisions with the use of .fc or .te suffixes in the
per-device directories. If we want multiple file support, add a separate
subdirectory for sepolicy files.
