Nothing should be depending on the details.
I haven't removed public/shared_relro.te entirely - there's a reference to shared_relro in public/app.te, and at least one reference to the domain outside of system policy.
Fix: 175867372
Test: Presubmits
Change-Id: I5fd4090f4b445520c4fa767c1835a5bb4e9cb146
Use of StrictMode in framework code running in the app process can
generate a denial:
avc: denied { find } for pid=4050 uid=1037 name=network_management
scontext=u:r:shared_relro:s0:c13,c260,c512,c768
tcontext=u:object_r:network_management_service:s0
tclass=service_manager permissive=0
But the code handles the failure properly so we suppress this.

Apps now all share the appdomain_tmpfs type.
Bug: 122854450
Test: boot Blueline with memfd enabled.
Change-Id: I5eac0adc7ecd10d19aa1bdf5f72efc7ed2a3a548
This is being done in preparation for the migration from ashmem to
memfd. In order for tmpfs objects to be usable across the Treble
boundary, they need to be declared in public policy whereas, they're
currently all declared in private policy as part of the
tmpfs_domain() macro. Remove the type declaration from the
macro, and remove tmpfs_domain() from the init_daemon_domain() macro
to avoid having to declare the *_tmpfs types for all init launched
domains. tmpfs is mostly used by apps and the media frameworks.

Test: Boot Taimen and blueline. Watch videos, make phone calls, browse
internet, send text, install angry birds...play angry birds, keep
playing angry birds...

(cherry picked from commit e16fb9109c)
Allow the shared_relro creation process to make calls to PackageManager,
so that it can create a classloader corresponding to the current WebView
implementation. This avoids needing to pass an absolute path to the
native library to the process, which required that the calling code
duplicate existing logic in the framework to find the library and
resulted in bugs and inconsistencies.

The comment in the policy implied this was already the case, but it
wasn't actually being used and appears to have been removed. This will
now be required by a framework change, so actually add the rule to allow
it.

This attribute is being actively removed from policy. Since
attributes are not being versioned, partners must not be able to
access and use this attribute. Move it from private and verify in
the logs that rild and tee are not using these permissions.
Bug: 38316109
Test: build and boot Marlin
Test: Verify that rild and tee are not being granted any of these
permissions.

(cherry picked from commit 76aab82cb3)
app_domain was split up in commit: 2e00e6373f to
enable compilation by hiding type_transition rules from public policy. These
rules need to be hidden from public policy because they describe how objects are
labeled, of which non-platform should be unaware. Instead of cutting apart the
app_domain macro, which non-platform policy may rely on for implementing new app
types, move all app_domain calls to private policy.

Test: bullhead and sailfish both boot. sediff shows no policy change.
Change-Id: I4beead8ccc9b6e13c6348da98bb575756f539665
Divide policy into public and private components. This is the first
step in splitting the policy creation for platform and non-platform
policies. The policy in the public directory will be exported for use
in non-platform policy creation. Backwards compatibility with it will
be achieved by converting the exported policy into attribute-based
policy when included as part of the non-platform policy and a mapping
file will be maintained to be included with the platform policy that
maps exported attributes of previous versions to the current platform
version.
Eventually we would like to create a clear interface between the
platform and non-platform device components so that the exported policy,
and the need for attributes is minimal. For now, almost all types and
avrules are left in public.
Test: Tested by building policy and running on device.
