system_file_type is a new attribute used to identify files which exist
on the /system partition. It's useful for allow rules in init, which are
based off of a blacklist of writable files. Additionally, it's useful
for constructing neverallow rules to prevent regressions.
Additionally, add commented out tests which enforce that all files on
the /system partition have the system_file_type attribute. These tests
will be uncommented in a future change after all the device-specific
policies are cleaned up.
Test: Device boots and no obvious problems.

/system/usr/share/zoneinfo is currently labeled zoneinfo_data_file,
a label shared with /data/misc/zoneinfo. However, each of these
directory locations has different security characteristics. In
particular, the files in /system/usr/share/zoneinfo must never be
writable, whereas /data/misc/zoneinfo may be written to by system_server.
Reusing the same label hides these different security characteristics.
Create a separate label for /system/usr/share/zoneinfo.
Test: Device boots and no obvious problems.

Otherwise we crash on a null pointer exception.
Test: Reference a non-existent type in test code and make sure
the test doesn't crash.

system/sepolicy/public/attributes defines exec_type as:
# All types used for domain entry points.
attribute exec_type;
The linker is not a standalone executable, but rather, used by other
executables to resolve shared libraries. It isn't, and must never be, an
allowed entrypoint for a domain.
Remove the exec_type attribute from system_linker_exec.
Test: Device compiles and boots, no obvious problems running the system.

All the *.conf.dontaudit files are generated from *.conf
with the command of 'sed '/dontaudit/d' $@ > $@.dontaudit',
but this command can not be applied to multi-line dontaudit statement.
Test: Set plat_policy.conf.dontaudit as the input_file parameter of
checkpolicy tool, then selinux syntax error will occur during building.

Do not attempt to build odm_sepolicy.cil if BOARD_ODM_SEPOLICY_DIRS is
not defined. Attempting to do so will create an empty file, which causes
build problems when
0c6ea1e812
is applied.
Test: "cd system/sepolicy && mma -j55" succeeds
Test: "make checkbuild" succeeds

Create a new service type buffer_hub_binder_service for
BufferHubBinderService and allow bufferhubd to publish the service.
Add the service to 26.0, 27.0 and 28.0 compat ignore files since the
service is not available in past versions.
Fixes: 116022258
Test: build passed
