829f7c72e5 ConnectivityService: listen to USER_UNLOCKED too
When the credential-encrypted private storage for the target user is
unlocked, we should try to start up VPN for them.

01cb4ff14d Implementation of data usage callbacks.
NetworkStatsService will register data usage requests
and keep data usage stats scoped to the request.

There are different types of data usage requests
- scoped to a set of NetworkTemplate; these are restrictred to
device owners and carrier apps and allow the caller to monitor
all activity on the specified interfaces.
- scoped to all uids visible to the user, if the user has
android.Manifest.permission#PACKAGE_USAGE_STATS permission.
The set of uids may change over time, so we keep track of that.
- scoped to a set of uids given by the caller, granted that
the caller has access to those uids.
- scoped to the caller's own data usage. This doesn't require
PACKAGE_USAGE_STATS.

With this it's possible for callers to:

    Network network = ...
    LinkProperties lp = ...

    NetworkDiagnostics netdiag = new NetworkDiagnostics(network, lp, 5000);
    netdiag.startMeasurements();
    netdiag.waitForMeasurements();

    boolean result = true;
    for (Measurement m : netdiag.getMeasurements()) {
        if (!m.checkSucceeded()) {
            result = false;
            // Additional error handling here.
        }
    }

    return result;

f73c15c090 Notify NetworkStatsService of roaming status changes.
When the roaming status of the cell network changes, it is handled as
follows:

-DcActiveState gets an event (either EVENT_DATA_CONNECTION_ROAM_ON or
 EVENT_DATA_CONNECTION_ROAM_OFF) and calls
 NetworkAgent#sendNetworkInfo with updated NetworkInfo.
-ConnectivityService then gets an EVENT_NETWORK_INFO_CHANGED and calls
 updateNetworkInfo with the new info.

With the previous code, the NetworkAgent's NetworkInfo object would be
updated internally, but because the state of the connection had not
changed from CONNECTED, the change would be considered a duplicate and
otherwise ignored.

With the new code, we call notifyIfacesChanged() when the state is the
same but the roaming status has changed. That should be all that is
necessary, as roaming is not exposed as a link property or network
capability today.

Jeff Davidson
2fd68b3a3e Implement roaming tracking in NetworkStats summary queries.
Whether a network is deemed roaming or not was already being tracked
as part of the NetworkIdentitySet, so the underlying data store
already tracks roaming and native data separately. However, this data
was being aggregated together in NetworkStatsCollection#getSummary,
since the NetworkIdentitySet is converted to an iface name for the
purposes of matching, and the iface name will be identical whether or
not the iface is considered roaming. Now it is separated.

Also fixes a long-standing bug in NetworkIdentitySet where an identity
read from a saved file would always be considered roaming == false,
even if it wasn't at the time it was written.

9786d92050 Allow NetworkFactories to match any network specifier on a request
Current usage of NetworkSpecifier: network factory will match a request
if the request has either a (1) empty network specifier, or (2) a
network specifier which is identical to that of the network factory.
Note: 'matching' w.r.t. network specifier - all other matching rules
are still in effect.

Change: add rule (3) or the network specifier of the network factory
is the special string (which is defined as "*" and which user-facing
network requests aren't allowed to use).

Rationale: allows on-demand network creation.

Example:
- Can specify a Wi-Fi NetworkRequest with NetworkSpecifier="ssid"
- It will match a Wi-Fi network factory specifying NetworkSpecifier="*"
- That network factory will bring up a Wi-Fi network, connecting to the
  specified SSID.
- Once the network is created it will create a NetworkAgent which will
  now have a NetworkSpecifier matching that of the request (not the
  match-all special string!)

That final step of making sure that the NetworkAgent matches the request
and not the match-all is critical to delivering any subsequent callbacks
correctly. I.e. your network will only get callbacks which match it.

aa65e9c069 Relax permissions around NetworkStatsManager APIs.
Currently, access to network usage history and statistics requires a
signature|privileged permission, an AppOps bit (associated with the
PACKAGE_USAGE_STATS permission), or device/profile ownership. Once
access is granted via one of these mechanisms, it generally applies to
any UID running in the same user as the caller.

This CL expands access as follows:

-Any app can access its own usage history with no extra requirements.
-Carrier-privileged applications can access usage history for the
entire device.
-Device owners can access per-UID breakdowns for usage. Previously
they could access the summary for the whole device, but not the
individual breakdowns.

We simplify the permission model by defining three access levels -
DEFAULT (own app only), USER (all apps in the same user), and DEVICE
(all apps on the device), and propagate these levels throughout.

Finally, this CL fixes an apparent bug in
NetworkStatsSerice#hasAppOpsPermissions - if the AppOp bit was in
MODE_DEFAULT, hasAppOpsPermission would always return false instead of
falling back to the PackageManager permission check.

98048cdb2b DO NOT MERGE Introduce direct listener API for alarm delivery
The Alarm Manager now supports a set() variant that takes a listener
callback to invoke at alarm trigger time rather than a PendingIntent.
This is much lower overhead and has guaranteed low delivery latency
from the trigger time.  The tradeoff is that the app must be running
*continuously* from the time the alarm is set to the time it is
delivered.  If the app exits for any reason before the alarm fires,
the listener becomes invalid and the alarm will be dropped.  This is
more or less equivalent to setting an alarm with a broadcast
PendingIntent that matches only a runtime-registered receiver.

The app's alarm listener can be any object that implements the new
AlarmManager.OnAlarmListener interface and implements its onAlarm()
method.  There is no data delivered at alarm trigger time: whatever
state needs to be associated with the specific alarm instance should
simply be packaged inside the OnAlarmListener instance.

An alarm using OnAlarmListener can request that the onAlarm() method
be called on an arbitrary handler.  If the program passes 'null' for
this parameter when setting the alarm, the callback occurs on the
application's main Looper thread.

You can now control the range of target SDKs that receivers

Use this for CONNECTIVITY_ACTION to not allow N+ applications

Also tweak the broadcast debug output code to now include the
disposition of each receiver in the list.  This is becoming
important as skipping receivers is becoming a more common
thing to have happen.

Lorenzo Colitti
0b40c87afc Reinstate CHANGE_NETWORK_STATE as a normal permission.
This is a partial revert of http://ag/738523 , but not a full
revert because M apps that have gone through the WRITE_SETTINGS
route to obtain permission to change network state should
continue to have permission to do so.

Specifically:

1. Change the protection level of CHANGE_NETWORK_STATE back from
   "signature|preinstalled|appop|pre23" to "normal". This allows
   apps that declare CHANGE_NETWORK_STATE in their manifest to
   acquire it, even if they target the M SDK or above.
2. Change the ConnectivityManager permission checks so that they
   first check CHANGE_NETWORK_STATE, and then ask Settings
   if the app has the WRITE_SETTINGS runtime permission.
3. Slightly simplify the code in the Settings provider code that
   deals specifically with the ability to change network state.
4. Make the ConnectivityService permissions checks use the
   ConnectivityManager code to avoid code duplication.
5. Update the ConnectivityManager public Javadoc to list both
   CHANGE_NETWORK_STATE and WRITE_SETTINGS.

c8d52c6993 Make ConnectivityServiceTest a bit more readable.
1. Make TestNetworkCallback a bit smarter and rename it to
   SingleUseNetworkCallback. This allows us to get rid of all the
   calls to TestNetworkCallback#getConditionVariable.
2. Delete the commented out code that used to test a
   ConnectivityService model that has not been used since KK.
3. Remove unused imports, etc.
