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.

The linker now requires getattr rights for the filesystem. Otherwise
linking otapreopt and patchoat/dex2oat will fail.

The PackageManager now passes previous code paths to dex2oat as shared
libraries. dex2oat needs extra permissions in order to access and open
the oat files of these libraries (if they were compiled).
Part of a multi-project change.

/vendor/framework is now designated location for vendor's platform
libraries. The directory is thus only made available for 'dex2oat'
coredomain.

The change makes 'vendor_app_file' accessible only to few platform
domains like dex2oat, idmap, installd, system_server and appdomain.

Remove system_file:file { lock ioctl } from domain_deprecated. The only
domains triggering this were dex2oat and netd, which are fixed in this
change.
Addresses the following logspam similar to:
avc: granted { lock } for comm="iptables"
path="/system/etc/xtables.lock" dev="sda22" ino=3745
scontext=u:r:netd:s0 tcontext=u:object_r:system_file:s0 tclass=file
avc: granted { lock } for comm="dex2oat"
path="/system/framework/arm/boot-okhttp.art" dev="dm-0" ino=1295
scontext=u:r:dex2oat:s0 tcontext=u:object_r:system_file:s0 tclass=file
Test: device boots and no obvious problems.

The secondary dex files are application dex files which gets reported
back to the framework when using BaseDexClassLoader.
Also, give dex2oat lock permissions as it needs to lock the profile
during compilation.

Since it was introduced it caused quite a few issues and it spams the
SElinux logs unnecessary.
The end goal of the audit was to whitelist the access to the
interpreter. However that's unfeasible for now given the complexity.

no more auditallow logs

This CLs adds SElinux policies necessary to compile secondary dex files.
When an app loads secondary dex files via the base class loader the
files will get reported to PM. During maintance mode PM will compile the
secondary dex files which were used via the standard installd model
(fork, exec, change uid and lower capabilities).
What is needed:
dexoptanalyzer - needs to read the dex file and the boot image in order
to decide if we need to actually comppile.
dex2oat - needs to be able to create *.oat files next to the secondary
dex files.
Test: devices boots
compilation of secondary dex files works without selinux denials

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.
