Now that we have sepolicy module in Android.bp, we can migrate contexts
tests. Also vendor_service_contexts_test will be run, as we now include
vendor_service_contexts unconditionally.
Unfortunately, vendor_service_contexts_test is now broken, due to a
malformed type hal_power_stats_vendor_service. We will temporarily
exempt the type from the test, to speed up migrating to Android.bp.
Bug: 33691272
Test: m selinux_policy and see tests running
Test: add a malformed type other than hal_power_stats_vendor_service and
run tests

compat_test tests whether {ver}.compat.cil is compatible to current
policy or not. This commit migrates all tests into a single module named
"sepolicy_compat_tests".
A minor issue is also resolved with this migration. Suppose that the
vendor's speolicy version is {VER}. Then the following cil files are
compiled in runtime.
- system/etc/selinux/plat_sepolicy.cil
- system/etc/selinux/mapping/{VER}.cil
- system/etc/selinux/mapping/{VER}.compat.cil (optional)
- system_ext/etc/selinux/system_ext_sepolicy.cil (optional)
- system_ext/etc/selinux/mapping/{VER}.cil (optional)
- system_ext/etc/selinux/mapping/{VER}.compat.cil (optional)
- product/etc/selinux/product_sepolicy.cil (optional)
- product/etc/selinux/mapping/{VER}.cil (optional)
- product/etc/selinux/mapping/{VER}.compat.cil (optional)
- vendor/etc/selinux/vendor_sepolicy.cil
- vendor/etc/selinux/plat_pub_versioned.cil
- odm/etc/selinux/odm_sepolicy.cil (optional)
That is, the vendor policy of version {VER} (vendor_sepolicy.cil,
plat_pub_versioned.cil, and odm_sepolicy.cil) is required to be
compatible only to {VER}.compat.cil. So, the vendor policy is included
only to $(BOARD_SEPOLICY_VERS)_compat_test. The other tests will be
built only with platform side policies.

Test: boot
Test: manually edit {ver}.compat.cil files and try build

sepolicy is a module which outputs precompiled sepolicy and performs
permissive domain check on user builds. se_policy_binary module is
updated so it checks permissive domain in user builds.

precompiled_sepolicy is used.

BOARD_PLAT_VENDOR_POLICY should be used for all vendor stuff, when in
mixed sepolicy build (BOARD_SEPOLICY_VERS != PLATFORM_SEPOLICY_VERSION).
This fixes an issue that system/sepolicy/vendor has been incorrectly

Steps taken to produce the mapping files:
1. Add prebuilts/api/32.0/plat_pub_versioned.cil from the
/vendor/etc/selinux/plat_pub_versioned.cil file built on sc-v2-dev with
lunch target aosp_arm64-eng. Add prebuilts/api/32.0/vendor_sepolicy.cil
as an empty file.
When adding plat_pub_versioned.cil, leave only type and typeattribute
statements, removing the other statements: allow, neverallow, role, etc.
2. Add new file private/compat/32.0/32.0.cil by doing the following:
- copy /system/etc/selinux/mapping/32.0.cil from sc-v2-dev
aosp_arm64-eng device to private/compat/32.0/32.0.cil
- remove all attribute declaration statement (typeattribute ...) and
sort lines alphabetically
- some selinux types were added/renamed/deleted w.r.t 32 sepolicy.
Find all such types using treble_sepolicy_tests_32.0 test.
- for all these types figure out where to map them by looking at
31.0.[ignore.]cil files and add approprite entries to 32.0.[ignore.]cil.
This change also enables treble_sepolicy_tests_32.0 and installs
32.0.cil mapping file onto the device.

build_policy gathers a list of files for a given set of folders and
filenames. It's possible that a certain folder doesn't have a certain
filename, in which case the $(wildcard) command will resolve to an
empty string, and there will be sections of many contiguous spaces
in the resulting list of files.
These contiguous spaces can show up in the build.ninja files.
When using a starlark-based device configuration, the number of spaces
is slightly different.
$(strip) not only removes spaces from the beginning/end of text, but
it also deduplicates any spaces in the middle. Use it to get rid
of the extra spaces so we have more consistent build.ninja files.

2. Add new file private/compat/31.0/31.0.cil by doing the following:
- copy /system/etc/selinux/mapping/31.0.cil from sc-dev aosp_arm64-eng
device to private/compat/31.0/31.0.cil
- remove all attribute declaration statement (typeattribute ...) and
sort lines alphabetically
- some selinux types were added/renamed/deleted w.r.t 31 sepolicy.
Find all such types using treble_sepolicy_tests_31.0 test.
- for all these types figure out where to map them by looking at
30.0.[ignore.]cil files and add approprite entries to 31.0.[ignore.]cil.
This change also enables treble_sepolicy_tests_31.0 and installs
31.0.cil mapping file onto the device.

Types defined in system_ext/public or product/public

to make sure functionality is not broken across version
bumps. So we are adding the treble sepolicy test cases

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.

Reason for revert: fixed breakage
The breakage was due to the difference between plat_sepolicy.conf and

se_policy_conf module, so it is synced with plat_sepolicy.conf

- system_ext_pub_policy.cil
