In kernel 4.7, the capability and capability2 classes were split apart
from cap_userns and cap2_userns (see kernel commit
8e4ff6f228e4722cac74db716e308d1da33d744f). Since then, Android cannot be
run in a container with SELinux in enforcing mode.
This change applies the existing capability rules to user namespaces as
well as the root namespace so that Android running in a container
behaves the same on pre- and post-4.7 kernels.
This is essentially:
1. New global_capability_class_set and global_capability2_class_set
that match capability+cap_userns and capability2+cap2_userns,
respectively.
2. s/self:capability/self:global_capability_class_set/g
3. s/self:capability2/self:global_capability2_class_set/g
4. Add cap_userns and cap2_userns to the existing capability_class_set
so that it covers all capabilities. This set was used by several
neverallow and dontaudit rules, and I confirmed that the new
classes are still appropriate.
Test: diff new policy against old and confirm that all new rules add
only cap_userns or cap2_userns;
Boot ARC++ on a device with the 4.12 kernel.

New binder kernel changes extend the areas where
binder will set real-time scheduling priorities
on threads; to make sure the driver can correctly
determine whether a process is allowed to run
at real-time priority or not, add the capability
to the services that need it.
Bug: 37293077
Test: processes run at real-time prio on incoming
real-time binder calls.

This adds fine-grained policy about who can register and find which

This switches Sensors HAL policy to the design which enables us to
conditionally remove unnecessary rules from domains which are clients
of Sensors HAL.
Domains which are clients of Sensors HAL, such as system_server, are
granted rules targeting hal_sensors only when the Sensors 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_sensors are
not granted to client domains.
Domains which offer a binderized implementation of Sensors HAL, such
as hal_sensors_default domain, are always granted rules targeting
hal_sensors.
P. S. This commit also removes
allow system_server sensors_device:chr_file rw_file_perms
because this is device-specific and thus not needed in device-agnostic
policy. The device-specific policy of the affected devices already has
this rule.
Test: Device boots, no new denials
Test: adb shell dumpsys sensorservice
lists tons of sensors
Test: Proprietary sensors test app indicates that there are sensors
and that the app can register to listen for updates for sensors
and that such updates arrive to the app.
