Android R launching devices and newer must not ship with debugfs
mounted. For Android S launching devices and newer, debugfs must only be
mounted in userdebug/eng builds by init(for boot time initializations)
and dumpstate(for grabbing debug information from debugfs). This patch
adds a neverallow statement that prevents processes other than init
from being provided access to mount debugfs in non-user builds
when the flag PRODUCT_SET_DEBUGFS_RESTRICTIONS is set to true.

This reverts commit d869d02758.
Reason for revert: fixed breakage
The breakage was due to the difference between plat_sepolicy.conf and
microdroid_vendor_sepolicy.conf. Now vendor_sepolicy.conf is built with
se_policy_conf module, so it is synced with plat_sepolicy.conf
Test: boot microdroid with and without SANITIZE_TARGET=address

This replaces the following policy files with Android.bp modules:

- system_ext_sepolicy.cil
- product_sepolicy.cil

- system_ext_pub_policy.cil
- pub_policy.cil
- general_sepolicy.conf (for CTS)
Also microdroid's system policy now uses above.

The existing freeze test only covers the policy files in system/sepolicy
alone. There's demand from product teams that would like to implement a
freeze test for their sepolicy. Instead of letting them fork the freeze
test, we believe expanding the scope of the exising one is in the best
interest.
$FREEZE_TEST_EXTRA_DIRS and $FREEZE_TEST_EXTRA_PREBUILT_DIRS are added.
These build variables could be appended like $PRODUCT_PUBLIC_POLICY. The
product team are expected to maintain their policy prebuilts.

Previously, soong emitted APEX_FILE_CONTEXTS_INFOS make var which lists
"all" APEXes and file_contexts.bin used all of them regardless whether
an APEX is installed or not.
This doesn't work when there's a vendor specific APEX which uses vendor
specific labels. Other lunch target may fail to build due to "unknown
label" which is introduced by the vendor APEX which is fact not supposed
to be installed.

Steps taken to produce the mapping files:
1. Add prebuilts/api/30.0/plat_pub_versioned.cil from the
/vendor/etc/selinux/plat_pub_versioned.cil file built on rvc-dev with
lunch target aosp_arm64-eng. Add prebuilts/api/30.0/vendor_sepolicy.cil
as an empty file.
2. Add new file private/compat/30.0/30.0.cil by doing the following:
- copy /system/etc/selinux/mapping/30.0.cil from rvc-dev aosp_arm64-eng
device to private/compat/30.0/30.0.cil
- remove all attribute declaration statement (typeattribute ...) and
sort lines alphabetically
- some selinux types were added/renamed/deleted w.r.t 30 sepolicy.
Find all such types using treble_sepolicy_tests_30.0 test.
- for all these types figure out where to map them by looking at
29.0.[ignore.]cil files and add approprite entries to 30.0.[ignore.]cil.
This change also enables treble_sepolicy_tests_30.0 and installs
30.0.cil mapping file onto the device.

APEX modules can be configured with apex_name and file_contexts
properties.
- apex_name overrides the activation point
for example, if apex_name is 'foo', it will be flattened under
/system/apex/foo even if its name is 'bar'.
- file_contexts overrides file_contexts filename
for example, it file_contexts is 'foo',
/system/sepolicy/apex/foo-file_contexts should be used even if its
name is 'bar'.
Previously, file_contexts files for flattened apexes are assumed to have
names like "/system/sepolicy/apex/<apex_name>-file_contexts". But, as
described above, calculating <apex_name> from file entries might be
wrong
Now, it relies on Soong's makevar APEX_FILE_CONTEXTS_INFOS which is list of
<apex_name>:<file_contexts> pairs.

Some targets just need to extend product context files, e.g.,

This is to migrate sepolicy Makefiles into Soong. For the first part,
file_contexts, hwservice_contexts, property_contexts, and
service_contexts are migrated. Build-time tests for contexts files are
still in Makefile; they will also be done with Soong after porting the
module sepolicy.
The motivation of migrating is based on generating property_contexts
dynamically: if we were to amend contexts files at build time in the
future, it would be nicer to manage them in Soong. To do that, building
contexts files with Soong can be very helpful.

When TARGET_FLATTEN_APEX=true, APEX files are not packaged in *.apex
files but flattened to the system partition under /system/apex/<name>

because the per-APEX file_contexts were applied only when building

Public policy that is available to vendor (and odm) sepolicy is a
combination of system and product public sepolicy. Since "plat_" prefix
implies a pure system sepolicy component, drop "plat_" prefix from
"plat_pub_policy" to be consistent with naming in this file.

sed "-i" flag on Mac has different syntax than on Linux. Replace use of
sed with grep.
A simple fix like this should suffice for this case, but ideally, we
should maintain our own utils instead of using tools on the host

Product-specific sepolicy will be installed into /product/etc/selinux/*.
This change separates out /product/etc/selinux/product_sepolicy.cil out
of system sepolicy.
This file is merged into precompiled_sepolicy at build-time. In case
precompiled_sepolicy can't be used (e.g. system-only-ota), init wll
merge this file with the rest of the sepolicy at runtime.
I left TODOs to separate other product-specific SELinux artifacts out of
system.

The SELinux policy language supports an expandattribute statement.
Similar to the C "inline" declaration, this expands the permissions
associated with types, instead of using the attribute directly. Please
see
1089665e31
for more detail on this language option.
Expansion of attributes causes consistency problems with CTS. If a
neverallow rule exists which refers to an expanded attribute, the CTS
neverallow test will fail, because the policy does not have the
attribute embedded in it. Examples:
* b/119783042 (fixed in 536d3413b8)
* b/67296580 (fixed in 6f7e8609f9)
* b/63809360 (fixed in 89f215e6a0)
etc...
Instead of waiting for the CTS test to fail, modify the Android.mk file
so that we do checks similar to CTS. This allows us to fail at compile
time instead of waiting for a CTS bug. For example, for b/119783042,
instead of the compile succeeding, it will now fail with the following
error message:

Commit b4f17069b3 ("sepolicy: Drop

As these restrictions have been in place since 2015, we can safely
assume all usages of this have been cleaned up, and there is no further
need to check for this.

Pass LOCAL_ADDITIONAL_M4DEFS to m4 when building vendor_file_contexts
and odm_file_contexts. The build command attempts to use
PRIVATE_ADDITIONAL_M4DEFS - but this is not set in the target-specific
variables.
This allows using custom M4 macros when building non-platform
file_contexts.

Private types are not visible to vendor/odm policy, so we don't need mapping
entries for them.
We build platform-only public policy .cil file and give it as input to
treble_sepolicy_tests. Using this public policy the test can now figure out if
the newly added type in public or private.

Steps taken to produce the mapping files:
1. Add prebuilts/api/28.0/[plat_pub_versioned.cil|vendor_sepolicy.cil]
from the /vendor/etc/selinux/[plat_pub_versioned.cil|vendor_sepolicy.cil]
files built on pi-dev with lunch target aosp_arm64-eng
2. Add new file private/compat/28.0/28.0.cil by doing the following:
- copy /system/etc/selinux/mapping/28.0.cil from pi-dev aosp_arm64-eng
device to private/compat/28.0/28.0.cil
- remove all attribute declaration statement (typeattribute ...) and
sort lines alphabetically
- some selinux types were added/renamed/deleted w.r.t 28 sepolicy.
Find all such types using treble_sepolicy_tests_28.0 test.
- for all these types figure out where to map them by looking at
27.0.[ignore.]cil files and add approprite entries to 28.0.[ignore.]cil.
This change also enables treble_sepolicy_tests_28.0 and install 28.0.cil
mapping onto the device.

Create one _system and one _nonsystem target, which together contains
the same artifacts as before, just split by whether they go on the
system partition or not.
The product build hierarchy is being refactored to be split by
partition, so these targets facilitate inclusion of just the
system parts where necessary. Also keep the selinux_policy target
around for products that don't need the split.
