      crash_dump_fallback: allow dumpstate:pipe_file write. · 7aa08523
      Josh Gao authored 
      It appears that selinux requires the write permission to receive
a writable pipe from dumpstate, for unclear reasons. Add the permission
for now.

Test: dumpstate

      Fix coredomain violation for modprobe · e41af203
      Sandeep Patil authored 
      
modprobe domain was allowed to launch vendor toolbox even if its a
coredomain. That violates the treble separation. Fix that by creating a
separate 'vendor_modprobe' domain that init is allowed to transition to
through vendor_toolbox.

      Verify correct application of labels and attributes · bdfc0301
      Jeff Vander Stoep authored 
      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
