With project Treble, we're relying heavily on attributes for
permission inheritance and enforcement of separation between
platform and vendor components.
We neead tests that verify those attributes are correctly applied.
This change adds the framework for those tests including a wrapper
around libsepol for loading and querying policy, and a python module
for running tests on policy and file_contexts.
Included with the testing framework is a test asserting that the
coredomain attribute is only applied to core processes. This
verification is done using the following rules:
1. Domain's entrypoint is on /system - coredomain
2. Domain's entrypoint is on /vendor - not coredomain
3. Domain belongs to a whitelist of known coredomains - coredomain
In a subsequent commit these tests will be applied at build time.
However, I first need to fix existing Treble violations exposed by
this test. These tests will also be applied during CTS.
Test: LD_PRELOAD=$ANDROID_HOST_OUT/lib64/libsepolwrap.so python \
treble.py -p $OUT/vendor/etc/selinux/precompiled_sepolicy \
-f $OUT/vendor/etc/selinux/nonplat_file_contexts \
-f $OUT/system/etc/selinux/plat_file_contexts
