Network usage is tracked by the kernel at the UID level, which is
granular enough for normal apps, but large components (such as the
system server) are impossible to debug without adding additional
socket tagging to help identify subsystems within a UID.
To help ensure that system components tag all their network traffic,
this change offers a new StrictMode option to detect and report
untagged sockets.
Test: builds, boots, all common traffic tagged

Symptom : Infinite reboot
Reproduce step :
1. Set the Always-on VPN in M OS
2. OS upgrade from M to N
Reproduce frequency : 100%
Reason of issue :
https://android.googlesource.com/platform/frameworks/base/+/9b74791
As you know, in M OS, Always-on VPN information is stored in keystore with encryted.
However, in N OS, there is no encryption when it put in keystore.
So, You deleted keystore check(locked/unlock) logic on ConnectivityService.
By this reason, when device upgrade to N OS(set Always-on VPN), it goes infinite boot.
(Cannot read old always-on vpn information untill device unlock.)
Solution :
I founded exception handling when this case as follows:
If getting Credentials.LOCKDOWN_VPN information has null value(catch the exception),
updateLockdownVpn returns false value.

This is the same notification as the one shown during legacy lockdown
mode, sans the 'reset' button.
The notification is only shown during times when VPN has not yet
established or has failed, for example during boot or after a crash.

This patch introduces an assertEventuallyThat helper function in
ConnectivityServiceTest which given a boolean function retries until the
function returns true or until a maximum retry time is reached.
This function is used to fix flakyness of testAvoidBadWifiSetting where
the Message posted by reevaluate() could reach the Handler's
MessageQueue after waitForIdle takes effect, resulting in the test to
fail.
Instead of fixing the flakyness by introdcing hard sleep times,
assertEventuallyThat is used to reduce the overall test time.
With this change the test has been observed to pass with 100% success
rate over 50000 invocations.

This patch fixes flakyness of testRequestBenchmark by adjusting time
limit for callback registration from 100ms to 180ms, and time limits for
onAvailable and onLost triggers from 30ms to 40ms.
With these timeouts the test succeeds 100% over 5000 iterations.
When using 150ms for registration timeout, running the test 5000 times
fails 2 times.
When using 30ms for onLost timeout, running the test 5000 times fails
1 times.
In addition, this patch also cleans testRequestBenchmark and uses the
more stable SystemClock.elapsedRealtime() for duration measurements.

This patch changes the way that the ConnectivityThread is lazily
instantiated by using the "lazy initialization holder class idiom".
The first code point that tries to obtain a reference to the unique
ConnectivityThread instance will trigger the creation of the Singleton
class, which will guarantee a thread-safe initialization of the static
INSTANCE field inside Singleton according to the language specs.
This is the Item #71 of Effective Java.
The unique static instance of ConnectivityThread is not stored directly
inside ConnectivityThread class but is stored in a static nested class.
This is to avoid triggering the creation of that unique instance when
Zygote does class preloading at phone startup. Otherwise this would lead
to Zygote creating a new OS thread during preloading, which is a fatal
error.

This patch removes the static singleton looper used by
ConnectivityManager and instead uses the common ConnectivityThread.
This allows to removes the static atomic counter used to track
the number of registered NetworkCallback in ConnectivityManager, because
the looper is not turned off anymore when no callbacks are registered.
Also an overloaded version of sendRequestForNetwork is added taking as a
new parameter a Handler. This will allow to overload various callback
and request related API calls with user provided Handlers.

This patch simplifies CallbackHandler in the following way:
- CallbackHandler directly uses the static references to
sNetworkCallback and sCallbackRefCount. This allows to remove
instance fields in CallbackHandler.
- CallbackHandler does not have a reference to ConnectivityManager
anymore
- CallbackHandler.getObject() is now generic in a type-safe way.

Removing the static dependency on guava reduces test compile time
by about 20 seconds on a Z840, thus substantially speeding up the
compile/test cycle.
Make FutureIntent public instead of package-private because it is
used directly by NetworkPolicyManagementServiceTest, which as of
this CL is now in a different package.

This patch extracts into its own independent test a test sub-block looking
for a race condition when not waiting on handlers to become idle:
there is no way to prevent the race from not happening when looking for
it this way. This makes the test flakky.
This new independent test is tagged with @FlakkyTest(tolerance = 3).
Test: ConnectivityServiceTest passes, with higher probability.

When network setting reset is started while always-on VPN is enabled,
application crash occurs with IllegalStateException in prepareVpn().
Therefore, it's necessary to also disable always-on VPN in factoryReset
before prepareVpn() when turning off VPN.
