This change adds the support of odm sepolicy customization, which can
be configured through the newly added build varaible:
- BOARD_ODM_SEPOLICY_DIRS += device/${ODM_NAME}/${BOM_NAME}/sepolicy
Also moving precompiled sepolicy to /odm when BOARD_ODM_SEPOLICY_DIRS
is set. On a DUT, precompiled sepolicy on /odm will override the one in
/vendor. This is intentional because /odm is the hardware customization
for /vendor and both should be updated together if desired.

When building userdebug or eng builds, we still want to build the user

adds it to the neverallow check.

This patch adds a flag that can be used to ignore neverallow rules.
By adding
SELINUX_IGNORE_NEVERALLOWS := true
into the BoardConfig.mk file, neverallow violations will be ignored
silently. This flag can only be enabled on userdebug and eng builds.
Users of this flag should be very careful. Since it does not work on
user builds, it must be disabled to pass CTS, and enabling it for
too long could hide issues that need to be addressed.
As a happy side effect, this patch should also improve the error
messages when violating a neverallow rules. Specifically, the file
and line number should be correct.

Platform SELinux policy may be updated without a corresponding
update to non-platform policy. This is meant to be accomplished by
maintaining a compatibility mapping file which will be built along
with the current platform policy to link older non-platform policy.
Introduce an example vendor policy built from 26.0 public policy and
make sure that the current platform policy and mapping file, for that
version, build with it. Add this as a dependency for the
selinux_treble_tests, which are meant to ensure treble properties,
ultimately to provide this compatibility guarantee.

has resulted in ordering variations.
Previously the binary file_contexts was preferred since it

This leaves us with build system complexity with no benefit.

testing purposes. This should not be a part of the released platform,
since the only public policy and corresponding mapping file construction
should be based on the current public platform policy, with compatibility
with vendor policy targeting previous versions provided by static mapping
files. Its continued presence muddles the generation of mapping files by
potentially introducing a situation in which an incorrect mapping file is
generated. Remove it.

As the platform progresses in the split SELinux world, the platform
will need to maintain mapping files back to previous platform versions
to maintain backwards compatibility with vendor images which have SELinux
policy written based on the older versions. This requires shipping multiple
mapping files with the system image so that the right one can be selected.
Change the name and location of the mapping file to reflect this. Also add
a file to the vendor partition indicating which version is being targeted that
the platform can use to determine which mapping file to choose.

Create PLATFORM_SEPOLICY_VERSION, which is a version string to represent
the platform sepolicy of the form "NN.m" where "NN" mirrors the
PLATFORM_SDK_VERSION and "m" is a policy-based minor version that is

mapping file to be added to allow for future-proofing vendor policy against
future platform policy.

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.

CTS includes general_sepolicy.conf built from this project. CTS then
tests this file's neverallow rules against the policy of the device
under test. Prior to this commit, neverallow rules which must be
enforced only for Treble devices we not included into
general_sepolicy.conf. As a result, these rules were not enforced for
Treble devices.
This commit fixes the issue as follows. Because CTS includes only one
policy, the policy now contains also the rules which are only for
Treble devices. To enable CTS to distinguish rules needed for all
devices from rules needed only on Treble devices, the latter rules are
contained in sections delimited with BEGIN_TREBLE_ONLY and
END_TREBLE_ONLY comments.
This commit also removes the unnecessary sepolicy.general target. This
target is not used anywhere and is causing trouble because it is
verifying neverallows of the policy meant to be used by CTS. This
policy can no longer be verified with checkpolicy without
conditionally including or excluding Treble-only neverallows.

This change associates all domains which are clients of Allocator HAL
with hal_allocator_client and the, required for all HAL client
domains, halclientdomain.
This enables this commit to remove the now unnecessary hwallocator_use
macro because its binder_call(..., hal_allocator_server) is covered by
binder_call(hal_allocator_client, hal_allocator_server) added in this
commit.
Unfortunately apps, except isolated app, are clients of Allocator HAL
as well. This makes it hard to use the hal_client_domain(...,
hal_allocator) macro because it translates into "typeattribute" which
currently does not support being provided with a set of types, such as
{ appdomain -isolated_app }. As a workaround, hopefully until
typeattribute is improved, this commit expresses the necessary
association operation in CIL. private/technical_debt.cil introduced by
this commit is appended into the platform policy CIL file, thus
ensuring that the hack has effect on the final monolithic policy.
P. S. This change also removes Allocator HAL access from isolated_app.
Isolated app shouldn't have access to this HAL anyway.

On PRODUCT_FULL_TREBLE devices, non-vendor domains (except vendor
apps) are not permitted to use Binder. This commit thus:
* groups non-vendor domains using the new "coredomain" attribute,
* adds neverallow rules restricting Binder use to coredomain and
appdomain only, and
* temporarily exempts the domains which are currently violating this
rule from this restriction. These domains are grouped using the new
"binder_in_vendor_violators" attribute. The attribute is needed
because the types corresponding to violators are not exposed to the
public policy where the neverallow rules are.

This adds build targets for outputing precompiled kernel policy usable
on devices with policy split between system and vendor partitions. On
such devices, precompiled policy must reside on the vendor partition.
Because such devices support updating these partitions independently
of each other, the precompiled policy must reference the system
partition's policy against which it was compiled. This enables init to
establish whether the precompiled policy is valid for the current
combination of system and vendor partitions.
The referencing is performed by both the system and vendor partitions
including the SHA-256 digest of the system partition's policy
(plat_sepolicy.cil). Only the when the digest is the same on both
partitions can the precompiled policy be used.
Test: plat_sepolicy.cil.sha256 contains exactly the hex form of the

Prior to this commit, there was a bug in generated CIL where it
wouldn't compile using secilc. The reason was that the build script
was stripping out all lines containing "neverallow" from CIL files,
accidentally removing lines which were not neverallow statements,
such as lmx lines referencing app_neverallows.te.
The commit fixes the build script's CIL neverallow filter to filter
out only neverallow* statements, as originally intended. Moreover, to
catch non-compiling CIL policy earlier in the future, this commit runs
secilc on the policy at build time. In particular, it tests that
platform policy compiles on its own and that nonplatform + platform +
mappig policy compiles as well.

Default HAL implementations are built from the platform tree and get
placed into the vendor image. The SELinux rules needed for these HAL
implementations to operate thus need to reside on the vendor
partition.
Up to now, the only place to define such rules in the source tree was
the system/sepolicy/public directory. These rules are placed into the
vendor partition. Unfortunately, they are also placed into the
system/root partition, which thus unnecessarily grants these rules to
all HAL implementations of the specified service, default/in-process
shims or not.
This commit adds a new directory, system/sepolicy/vendor, whose
rules are concatenated with the device-specific rules at build time.
These rules are thus placed into the vendor partition and are not
placed into the system/root partition.
Test: No change to SELinux policy.
Test: Rules placed into vendor directory end up in nonplat* artefacts,

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.

Strip whitespace and comments from service_context files
to reduce size. On an aosp_x86_64 build it saves 36 bytes.
However, on builds with more synclines and comments, further
space savings can be realized.

checkpolicy spits out a bunch of unnecessary lines during normal
operation, which bloat the logs and hide other more important
warnings. Suppress the normal output.
SELinux compile time errors are printed to stderr, and are
uneffected by this change.

It's a CTS requirement that all SELinux domains be in
enforcing mode. Add the same assertion to the build system
when targeting user builds.
In particular, this avoids a situation where device integrity
checking is enabled on user builds, but permissive denials
are being generated, causing the device to unexpectedly reboot
into safe mode.
A developer wanting to put an SELinux domain into permissive
mode for userdebug/eng purposes can write the following
in their policy:
userdebug_or_eng(`
permissive foo;
')

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.

Reduce the socket ioctl commands available to untrusted/isolated apps.
Neverallow accessing sensitive information or setting of network parameters.
Neverallow access to device private ioctls i.e. device specific
customizations as these are a common source of driver bugs.
Define common ioctl commands in ioctl_defines.

Android.mk: cleanse all set but not unset variables
Android.mk: clean dependencies and clear variables
Dependencies being built with newline files in between
were also including the list of files without the newlines,
thus make would have to process 3n-1 files instead of 2n-1
where n is the number of files to process.
Additionally the *_with_nl variables were not being cleared
out and polluting Make's global name-space.

The target sectxfile_nl, which is an auto-generated newline file,
has dependencies on itself and the other files. The dependencies
should be on the other files and this newline file, not the other
way around. Ideally, the *_contexts recipes should have the
dependency recorded for their "contexts" files and the newline
file.
Additionally, recipe dependencies for building the *_contexts files
depended on the list of all the contexts files with the newline file
in that list, however an additional explicit addition of the newline
file was also added in. Remove this, since its in the full list of
files.

Enable checkfc to check *_contexts against a set of valid attributes
which must be associated with all types in the contexts file that
is being checked.
Since it's imperative that checkfc knows which file its checking to
choose the proper attribute set, the -s option is introduced to
indicate the service_contexts file. The property_contexts file continues
to use the existing -p and file_contexts requires no specification, aka
it's the default.
Failure examples:
file_contexts:
Error: type "init" is not of set: "fs_type, dev_type, file_type"
service_contexts:
Error: type "init_exec" is not of set: "service_manager_type"
property_contexts:
Error: type "bluetooth_service" is not of set: "property_type"

When multiple file_contexts, service_contexts and property_contexts
are processed by the m4(1) macro processor, they will fail if one
or more of the intermediate files final line is not terminated by
a newline. This patch adds an intervening file only containing a
newline.

Temporarily move from policy version 30 to 29 until device kernels
and prebuilts are all upgraded to the accepted upstream version of
the selinux ioctl command whitelisting code.
