Wifi Keystore HAL is a HwBinder service (currently offered by keystore
daemon) which is used by Wifi Supplicant HAL. This commit thus
switches the SELinux policy of Wifi Keystore HAL to the approach used
for non-HAL HwBinder services.
The basic idea is simimilar to how we express Binder services in the
policy, with two tweaks: (1) we don't have 'hwservicemanager find' and
thus there's no add_hwservice macro, and (2) we need loosen the
coupling between core and vendor components. For example, it should be
possible to move a HwBinder service offered by a core component into
another core component, without having to update the SELinux policy of
the vendor image. We thus annotate all components offering HwBinder
service x across the core-vendor boundary with x_server, which enables
the policy of clients to contain rules of the form:
binder_call(mydomain, x_server), and, if the service uses IPC
callbacks, also binder_call(x_server, mydomain).

"tee" domain is a vendor domain. Hence its rules should live on the
vendor image.
What's left as public API is that:
1. tee domain exists and that it is permitted to sys_rawio capability,
2. tee_device type exists and apps are not permitted to access
character devices labeled tee_device.
If you were relying on system/sepolicy automatically labeling
/dev/tf_driver as tee_device or labeling /system/bin/tf_daemon as
tee_exec, then you need to add these rules to your device-specific

This futher restricts neverallows for sockets which may be exposed as
filesystem nodes. This is achieved by labelling all such sockets

Full treble targets cannot have sockets between framework and vendor
processes. In theory, this should not affect aosp_arm64_ab where only
framework binaries are built. However, /system/sepolicy has rild.te
which is now vendor binary and this causes neverallow conflict when
building aosp_arm64_ab.
So, we just temporarily annotate the rild with
socket_between_core_and_vendor_violators so that the neverallow conflict
can be avoided.

On PRODUCT_FULL_TREBLE devices, non-vendor domains (coredomain) and
vendor domain are not permitted to connect to each other's sockets.
There are two main exceptions: (1) apps are permitted to talk to other
apps over Unix domain sockets (this is public API in Android
framework), and (2) domains with network access (netdomain) are
permitted to connect to netd.
This commit thus:
* adds neverallow rules restricting socket connection establishment,
* temporarily exempts the domains which are currently violating this
rule from this restriction. These domains are grouped using the new
"socket_between_core_and_vendor_violators" attribute. The attribute
is needed because the types corresponding to violators are not

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.

This switches Boot Control HAL policy to the design which enables us
to conditionally remove unnecessary rules from domains which are
clients of Boot Control HAL.
Domains which are clients of Boot Control HAL, such as update_server,
are granted rules targeting hal_bootctl only when the Boot Control HAL
runs in passthrough mode (i.e., inside the client's process). When the
HAL runs in binderized mode (i.e., in another process/domain, with
clients talking to the HAL over HwBinder IPC), rules targeting
hal_bootctl are not granted to client domains.
Domains which offer a binderized implementation of Boot Control HAL,
such as hal_bootctl_default domain, are always granted rules targeting
hal_bootctl.
P. S. This commit removes direct access to Boot Control HAL from
system_server because system_server is not a client of this HAL. This
commit also removes bootctrl_block_device type which is no longer

This switches most remaining HALs to the _client/_server approach.
To unblock efforts blocked on majority of HALs having to use this
model, this change does not remove unnecessary rules from clients of
these HALs. That work will be performed in follow-up commits. This
commit only adds allow rules and thus does not break existing
functionality.
The HALs not yet on the _client/_server model after this commit are:
* Allocator HAL, because it's non-trivial to declare all apps except
isolated apps as clients of this HAL, which they are.
* Boot HAL, because it's still on the non-attributized model and I'm
waiting for update_engine folks to answer a couple of questions
which will let me refactor the policy of this HAL.

process). When the HAL runs in binderized mode (i.e., in another
process/domain, with clients talking to the HAL over HwBinder IPC),
rules targeting hal_keymaster are not granted to client domains.
Domains which offer a binderized implementation of Keymaster HAL, such
as hal_keymaster_default domain, are always granted rules targeting
hal_keymaster.

This switches Wi-Fi HAL policy to the design which enables us to
conditionally remove unnecessary rules from domains which are clients
of Wi-Fi HAL.
Domains which are clients of Wi-Fi HAL, such as system_server domain,
are granted rules targeting hal_wifi only when the Wi-Fi HAL runs in
passthrough mode (i.e., inside the client's process). When the HAL
runs in binderized mode (i.e., in another process/domain, with clients
talking to the HAL over HwBinder IPC), rules targeting hal_wifi are
not granted to client domains.
Domains which offer a binderized implementation of Wi-Fi HAL, such as
hal_wifi_default domain, are always granted rules targeting hal_wifi.

This switches Fingerprint HAL policy to the design which enables us to
conditionally remove unnecessary rules from domains which are clients
of Bluetooth HAL.
Domains which are clients of Fingerprint HAL, such as system_server
domain, are granted rules targeting hal_fingerprint only when the
Fingerprint HAL runs in passthrough mode (i.e., inside the client's
process). When the HAL runs in binderized mode (i.e., in another
process/domain, with clients talking to the HAL over HwBinder IPC),
rules targeting hal_fingerprint are not granted to client domains.
Domains which offer a binderized implementation of Fingerprint HAL,
such as hal_fingerprint_default domain, are always granted rules
targeting hal_fingerprint.
NOTE: This commit also removes unnecessary allow rules from
Fingerprint HAL, such access to servicemanager (not hwservicemanager)
and access to keystore daemon over Binder IPC. Fingerprint HAL does
not use this functionality anyway and shouldn't use it either.
Test: Enable fingerprint + PIN secure lock screen, confirm it unlocks
with fingerprint or PIN
Test: Disable PIN (and thus fingerprint) secure lock screen
Test: make FingerprintDialog, install, make a fake purchase
Test: Add fingerprint_hidl_hal_test to device.mk, build & add to device,
adb shell stop,
adb shell /data/nativetest64/fingerprint_hidl_hal_test/fingerprint_hidl_hal_test -- all tests pass

SELinux labeling of filesystem files ignores symlinks. Unfortunately,
/vendor is a symlink on devices without vendor partition
(e.g., hikey). Thus, policy in directories which are used both for
devices with vendor partition and for devices without vendor partition
must be adjusted to match both /vendor and /system/vendor. It is
assumed that the /vendor symlink, if it exists at all, always points
to /system/vendor.
The alternative solution of adjusting vendor policy file labelling
rules at vendor policy build time, when the actual on-device paths are
known, was considered to make it harder to see how files are labelled
by looking solely at the source tree.
Test: Files under /vendor/bin/hw correctly labelled on sailfish,
angler, and a device which uses the /vendor symlink.

This starts the switch for HAL policy to the approach where:
* domains which are clients of Foo HAL are associated with
hal_foo_client attribute,
* domains which offer the Foo HAL service over HwBinder are
associated with hal_foo_server attribute,
* policy needed by the implementation of Foo HAL service is written
against the hal_foo attribute. This policy is granted to domains
which offer the Foo HAL service over HwBinder and, if Foo HAL runs
in the so-called passthrough mode (inside the process of each
client), also granted to all domains which are clients of Foo HAL.
hal_foo is there to avoid duplicating the rules for hal_foo_client
and hal_foo_server to cover the passthrough/in-process Foo HAL and
binderized/out-of-process Foo HAL cases.
A benefit of associating all domains which are clients of Foo HAL with
hal_foo (when Foo HAL is in passthrough mode) is that this removes the
need for device-specific policy to be able to reference these domains
directly (in order to add device-specific allow rules). Instead,
device-specific policy only needs to reference hal_foo and should no
longer need to care which particular domains on the device are clients
of Foo HAL. This can be seen in simplification of the rules for
audioserver domain which is a client of Audio HAL whose policy is
being restructured in this commit.
This commit uses Audio HAL as an example to illustrate the approach.
Once this commit lands, other HALs will also be switched to this
approach.

hal_*_default daemons whose policy is in common/device-agnostic policy
are provided by the vendor image (see vendor/file_contexts). Thus,
their policy should also reside in the vendor image, rather than in
the system image. This means their policy should live in the vendor
subdirectory of this project.
