Require all domains which can be used for BPF to be marked as
bpfdomain, and add a restriction for these domains to not
be able to use net_raw or net_admin. We want to make sure the
network stack has exclusive access to certain BPF attach
points.

This partly reverts fa10a14fac. There we
removed individual labels for various apexdata labels, replacing them
with apex_system_server_data_file.
Unfortunately that doesn't handle upgrade scenarios well, e.g. when
updating system but keeping the old vendor sepolicy. The directories
keep their old labels, and vold_prepare_subdirs is unable to relabel
them as there is no policy to allow it to.
So we bring back the legacy labels, in private not public, and add the
rules needed to ensure system_server and vold_prepare_subdirs have the
access they need. All the other access needed is obtained via the
apex_data_file_type attribute.

System server needs to do this to know whether a suitable VM for
CompOS can be created. System server does not need the ability to
actually start a VM, so we don't grant that.

sepolicy_generate_compat is a binary that creates a new compat file when
freezing sepolicy API.
Suppose that we are adding {ver} compat file, after freezing {ver}
sepolicy. Then the workflow would be:
1) copy prebuilts to system/sepolicy/prebuilts/api/{ver}
2) add {ver} to PLATFORM_SEPOLICY_COMPAT_VERSIONS under
build/make/core/config.mk
3) touch the following three files
- system/sepolicy/private/compat/{ver}/{ver}.cil
- system/sepolicy/private/compat/{ver}/{ver}.compat.cil
- system/sepolicy/private/compat/{ver}/{ver}.ignore.cil
- system/sepolicy/prebuilts/api/{ver}/vendor_sepolicy.cil
- system/sepolicy/prebuilts/api/{ver}/plat_pub_versioned.cil
* This step is to build base compat files, and won't be needed in the
future.
4) add compat module files (won't be needed in the future)
- {ver}.cil
- {ver}.compat.cil
- {ver}.ignore.cil
* This step is to build base compat files, and won't be needed in the
future.
5) run the following command to update above three files:
$ source build/envsetup.sh && lunch aosp_arm64-userdebug
$ m sepolicy_generate_compat
$ sepolicy_generate_compat --branch=(branch_for_ver) \
--build latest --target-version {ver} \
--latest-version {ver-1}
6) upload build/make and system/sepolicy changes.
This script still lacks:
- handling of plat_pub_versioned.cil
- test cases
We will tackle such problems with follow-up changes.
