2a67e947c6 Use a property instead of file to communicate cold boot done
Ueventd can't set properties currently, but this is an artificial
limitation, since ueventd communicates to init that it has finished
cold boot via a file, and init polls this file instead of returning to
the epoll loop, where properties are handled.

A related change replaces that file with a property and thus frees
ueventd to be able to set properties.  This change creates the
cold_boot_done property type for this property and gives only ueventd
permissions to set it.

Bug: 62301678
Test: boot, check that properties are set

a999e39423 Add persist.sys.theme.

Test: Set a vendor init trigger that waits on `persist.sys.theme`. Check
      that the trigger fires without denial.

544a0d5480 Add new cpu variant related rules to SELinux
I added ro.bionic.(2nd_)?_(arch|cpu_variant) to vendor system
properties. And have init to write them to files under dev/.

This change set SELinux rules for these properties and files.

For the system properties: vendor/default.prop will set them. init will
read them.
For the files /dev/cpu_variant:.*: init will write them. bionic libc
will read them. (Basically world readable).

This is to allow libc select the right optimized routine at runtime.
Like memcpy / strcmp etc.

Test: getprop to make sure the properties are set.
Test: ls -laZ to make sure /dev/cpu_variant:.* are correctly labeled.

Jeff Vander Stoep
7745770bca Use non-expanded types in prop neverallows
Using hal_foo attributes in neverallow rules does not work because
they are auto-expanded to types. Use hal_foo_server types instead.

Fixes the following error:
unit.framework.AssertionFailedError: The following errors were
encountered when validating the SELinuxneverallow rule: neverallow
{ domain -coredomain -bluetooth -hal_bluetooth } { bluetooth_prop }:
property_service set; Warning! Type or attribute hal_bluetooth used
in neverallow undefined in policy being checked.

7b8be35ddf Finer grained permissions for ctl. properties
Currently, permissions for ctl. property apply to each action verb, so
if a domain has permissions for controlling service 'foo', then it can
start, stop, and restart foo.

This change implements finer grainer permissions such that permission
can be given to strictly start a given service, but not stop or
restart it.  This new permission scheme is mandatory for the new
control functions, sigstop_on, sigstop_off, interface_start,
interface_stop, interface_restart.

4f673cf4a9 Revert "Allow system server to set persist.traced.enable"
This reverts commit 6f2040f873.

Reason for revert: not needed anymore after ag/3773705
This was meant to allow system_server toggling the property on/off.
Later we realized that we needed a separate property for that 
(see discussion in b/76077784) and system server happens to
have already permissions to write to sys.* properties even without
this CL.
Reverting because at this point this creates just unnecessary clutter.

Denial:

scontext=u:r:system_server:s0
tcontext=u:object_r:default_prop:s0 tclass=property_service

Run:
$ adb shell 'ps -A | grep traced'
Should see traced.
$ adb shell 'settings put global sys_traced 0'
$ adb shell 'ps -A | grep traced'
Should no longer see traced.

eed2e84a95 Fix compatible property neverallows
The current neverallow rules for compatible properties restrict
domains from write file permissions to the various property files.
This however is the wrong restriction, since only init actually writes
to these property files.  The correct restriction is to restrict 'set'
for 'property_service' as this change does.

Note there is already a restriction preventing {domain -init} from
writing to these files in domain.te.

07e631d2e0 Temporarily revert the SELinux policy for persist.netd.stable_secret.
This change did not make it into core sepolicy in time for O.
The revert allows devices to define these selinux policies in
vendor-specific sepolicy instead of core sepolicy. It is
necessary because:

1. It is too late to change property_contexts in O.
2. Adding the netd_stable_secret prop to vendor sepolicy results
   in a duplicate definition error at compile time.
3. Defining a new vendor-specific context (such as
   net_stable_secret_vendor_prop) and applying it to
   persist.netd.stable_secret results in the device not booting
   due to attempting to apply two different contexts to the same
   property.

Lack of the sepolicy no longer breaks wifi connectivity now that
IpManager no longer considers failure to set the stable secret to
be a fatal error.

Once all interested devices have adopted the vendor sepolicy,
this policy can safely be reinstated by reverting said vendor
sepolicies in internal master.

This reverts commit abb1ba6532.

abb1ba6532 SELinux policy for secure persistent netd storage
This is used to persist RFC 7217 stable secrets across device reboots.

First submit caused a merge conflict. This revision replaces netd_prop
with a more unique name netd_stable_secret_prop.

Test: as follows
    - Manually tested that stable_secret is generated on first use and
      persists until reset of user data partition (factory reset).
    - Tested that "adb shell getprop" was denied access to
      persist.netd.stable_secret after running "adb unroot".
