The following denial caused a presubmit failure:
06-15 15:16:24.176 956 956 I auditd : type=1400 audit(0.0:4): avc:
denied { read write } for comm="crash_dump64" path="/dev/pts/3"

Suppress these denials. They are not needed by crash_dump and are only
caused by the default behavior of sharing FDs across exec.

In userdebug, for better diagnostics, allow crash_dump to "connect
to" apexd.
Considering apexd is quite powerful, user devices remain restricted.

And add neverallow so that it's removed from partner policy if
it was added there due to denials.

We're investigating a bug where vold gets wedged, and we need to
collect ANR stack traces from it to debug further.

apexd is a new daemon for managing APEX packages installed
on the device. It hosts a single binder service, "apexservice".
Bug: 112455435
Test: builds, binder service can be registered,
apexes can be accessed, verified and mounted

Add additional compile time constraints on the ability to ptrace various
sensitive domains.
llkd: remove some domains which llkd should never ptrace, even on
debuggable builds, such as kernel threads and init.
crash_dump neverallows: Remove the ptrace neverallow checks because
it duplicates other neverallow assertions spread throughout the policy.
Test: policy compiles and device boots
Change-Id: Ia4240d1ce7143b983bb048e046bb4729d0af5a6e
llkd needs the ptrace capabilities and dac override to monitor for
live lock conditions on the stack dumps.

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.
Test: mmm system/sepolicy
Test: Device boots, no new denials

Test: Google Camera: take a photo, take an HDR+ photo, record video with
sound, record slow motion video with sound. Confirm videos play
back fine and with sound.
