Static analyzer complains the memory pointed by list in bcurrent is not
deallocated before returning. But since this code is in "main" routine,
we don't care about the deallocation. Just ignore the warning.

Empty typeset is not an issue in neverallow rules. The reason is that
it's completly normal for scontext or tcontext of neverallow rules to
evaluate to an empty type set. For example, there are neverallow rules
whose purpose is to test that all types with particular powers are
associated with a particular attribute:
neverallow {
untrusted_app_all
-untrusted_app
-untrusted_app_25
} domain:process fork;
Test: sepolicy-analyze neverallow -w -n \
'neverallow {} {}:binder call;'
produces empty output instead of "Warning! Empty type set"

The sepolicy version takes SDK_INT.<minor> format. Make sure our
'current' policy version reflects the format and make it '100000.0'.
This ensures any vendor.img compiled with this will never work with
a production framework image either.
Make version_policy replace the '.' in version by '_' so secilc is
happy too.
This unblocks libvintf from giving out a runtme API to check vendor's
sepolicy version. The PLAT_PUBLIC_SEPOLICY_CURRENT_VERSION will
eventually be picked up from the build system.

sepolicy-analyze allows users to see all types that have a given
attribute, but not the reverse case: all attributes of a given type.
Add a '--reverse' option which enables this, but keeps the previous
interface.

This new input selector allows phasing in new security policies by
giving app developers an opportunity to make any needed compatibility
changes before updating each app's targetSdkVersion.
When all else is equal, matching entries with higher
minTargetSdkVersion= values are preferred over entries with lower
minTargetSdkVersion= values.
Test: Marlin builds and boots. Apps targeting targetSdkVersion<=25
run in untrusted_app_25 domain. Apps targeting the current development
build >=26 run in the untrusted_app domain with fewer permissions. No
new denials observed during testing.

In order to support platform changes without simultaneous updates from
non-platform components, the platform and non-platform policies must be
split. In order to provide a guarantee that policy written for
non-platform objects continues to provide the same access, all types
exposed to non-platform policy are versioned by converting them and the
policy using them into attributes.
This change performs that split, the subsequent versioning and also
generates a mapping file to glue the different policy components
together.
Test: Device boots and runs.

If in invalid policy file is loaded check_seapp outputs:
Error: Could not lod policy file to db: Success!
The "Success" value is from errno, which is not manipulated
by libsepol. Also, load should have an a in it!
Hardcode the error message to:
Error: Could not load policy file to db: invalid input file!
Test: That when providing an invalid sepolicy binary, that the output
message is correct.

Input validation was hard-coded into a validation routine
that would check against type and key names in a scattered,
order dependent conditional code block.
This makes it harder than it should be to add new key value
pairs and types into checkseapp.
To correct this, we add a validation callback into the
static mapping. If the validation callback is set, the
existing validation routine will call this for input
validation. On failure, a validation specific error message
is returned to be displayed.

Ordering matters in fc files; the last match wins. In builds where
many BOARD_SEPOLICY_DIRS are set, the order of that list becomes
increasingly important in order to maintain a cohesive built
file_contexts.
To correct this, we sort the device specific file_contexts entries
with the upstream fc_sort tool.

Checkfc was treating 0 size fc files as a fatal error.
An empty fc file should be treated as "nothing to check"
so long as the -e option is passed.
We add this option, so we don't allow empty file_context
files to pass CTS checking.
