889dd078e9 Add a new system property persist.graphics.egl
This new system property will be read and written
by a new developer option switch, through gpuservice.

Based on the value stored in persis.graphics.egl,
we will load different GLES driver.

e.g.
persist.graphics.egl == $ro.hardware.egl: load native GLES driver
persist.graphics.egl == angle: load angle as GLES driver

ccfb0ef146 Added properties for rebootless apex install
When apexd installs an apex without reboot, init also need to do some
work around the installation (e.g. terminating services from the apex
and remove data read from the apex and updating linker configuration
etc)

Apexd sets control properties to unload and load apex and init notifies
the completion with state properties.

These new properties are supposed to be used by apexd/init interaction.

a0b504a484 Add neverallows for debugfs access
Android R launching devices and newer must not ship with debugfs
mounted. For Android S launching devices and newer, debugfs must only be
mounted in userdebug/eng builds by init(for boot time initializations)
and dumpstate(for grabbing debug information from debugfs using the
dumpstate HAL).

This patch adds neverallow statements to prevent othe processes
being provided access to debugfs when the flag PRODUCT_SET_DEBUGFS_RESTRICTIONS
is set to true.

8b26472177 traced_perf: allow RO tracefs access + fix neverallow
We're adding support for counting and/or sampling on the static kernel
tracepoints in traced_perf (via perf_event_open). This requires traslating
a human-readable tracepoint name to its id for the running kernel.
For that, we need to read the "id" files like:
  /sys/kernel/tracing/events/sched/sched_switch/id

While the current implementation should only need "file r_file_perms",
as it constructs the full path to the id file, I've also added the
directory-level rule to allow for a possible change in implementation,
as we might want to enumerate all available events ahead of time, which
would require listing the tracefs events/ dir.

The changed neverallow macro was a copypaste mistake.

Example denials without the change:
  avc: denied { read } for name="id" dev="tracefs" ino=5721
  scontext=u:r:traced_perf:s0 tcontext=u:object_r:debugfs_tracing:s0
  tclass=file permissive=1

  avc: denied { open } for
  path="/sys/kernel/tracing/events/sched/sched_switch/id" dev="tracefs"
  ino=5721 scontext=u:r:traced_perf:s0
  tcontext=u:object_r:debugfs_tracing:s0 tclass=file permissive=1

  avc: denied { getattr } for
  path="/sys/kernel/tracing/events/sched/sched_switch/id" dev="tracefs"
  ino=5721 scontext=u:r:traced_perf:s0
  tcontext=u:object_r:debugfs_tracing:s0 tclass=file permissive=1

Tested: collected a profile sampled on "sched/sched_switch" on
        crosshatch-userdebug.

8c9cf62edb Allow coredomain access to only approved categories of vendor heaps
One of the advantages of the DMA-BUF heaps framework over
ION is that each heap is a separate char device and hence
it is possible to create separate sepolicy permissions to restrict
access to each heap.
In the case of ION, allocation in every heap had to be done through
/dev/ion which meant that there was no away to restrict allocations in
a specific heap.

This patch intends to restrict coredomain access to only approved
categories of vendor heaps. Currently, the only identified category
as per partner feedback is the system-secure heap which is defined
as a heap that allocates from protected memory.

Test: Build, video playback works on CF with ION disabled and
without sepolicy denials

082ced1951 Make default_prop only readable from coredomain
default_prop has been readable from coredomain and appdomain. It's too
broad, because default_prop is a context for properties which don't have
matching property_contexts entries.

From now on, only coredomain can read default_prop. It's still broad,
but at least random apps can't read default_prop anymore.

d5a0448a53 Add entries for some properties in default_prop
Currently default_prop is readable by coredomain and appdomain. That's
too broad, and we are going to restrict the access so every property
should be added to property_contexts.

This adds some missing properties to property_contexts. Newly added
property contexts are:

- wrap.*: used by zygote to give arguments. It's assigned as
zygote_wrap_prop, and will be readable from coredomain.

- partition.{mount_name}.verified: used by dm-verity. It's assigned as
vertiy_status_prop, and will only be accessible from init.

- (ro.)?setupwizard.*: used by setup wizard. It's assigned as
setupwizard_prop, and will be readable from coredomain.

Other properties, such as ro.gfx.*, media.stagefright.*,
ro.storage_manager.* are also added to existing contexts.
