Currently, we only count add tethering traffic to per-UID
stats, but not to total data usage (i.e., dev and XT stats). This
is correct for software tethering, because all software forwarded
packets are already included in interface counters, but it is
incorrect for hardware offload, because such packets do not
increment interface counters.
To fix this:
1. Add an argument to ITetheringStatsProvider#getTetherStats to
indicate whether per-UID stats are requested. For clarity,
define integer constants STATS_PER_IFACE and STATS_PER_UID
to represent these operations.
2. Make NetdTetheringStatsProvider return stats only if per-UID
stats are requested. (Otherwise tethering traffic would be
double-counted).
3. Make OffloadController's stats provider return the same
stats regardless of whether per-UID stats were requested or
not.
4. Make NetworkStatsService add non-per-UID tethering stats to
the dev and XT snapshots. The per-UID snapshots were already
correctly adding in per-UID stats.

Also moving relevant test files into tests/net as part of runtest
framworks-net.
Also removes testHashCode in LinkAddress() because this test relies on
the assumption that hashCode() is stable across releases or jdk
versions, which is absolutely not true.
This creates maintenance work for little benefit since hashCode is
already tested as part of the equality test.
For instance this test is now broken because hashing for InetAddress
changed.

This patch loosens the validation checks when a NetworkAgent updates it
NetworkCapabilities: instead of checking that capabilities labeled as
"immutable" stay identical across updates, it is now accepted to change
immutable capabilities in a way that the new NetworkCapabilities
satisfies the old NetworkCapabilities.
This allows a NetworkAgent to update itself in order to match more
requests, but will still catch NetworkAgents that sends degradation
updates causing potentially requests to not match anymore.

This patch moves reportNetworkConnectivity onto the handler of

which is always more correct than doing so on a Binder thread.
- to improve locking policies around NetworkAgentInfo.

This path changes a dangerous lock path in reportNetworkConnectivity().
This methods is called outside of the main ConnectivityService handler
and takes a lock on a specific NetworkAgentInfo whose connectivity
status is being reported.
While this lock is held, reportNetworkConnectivity() goes on and query
the network policy state for that network, which may ends into
NetworkPolicyManagerService.
Instead, the lock on NetworkAgentInfo is only held long enough to make a
copy of LinkProperties, which is then passed to
NetworkPolicyManagerService without that lock.

This patch corrects a regression added by commit 51727428fc that did
not take into account the case of multiple notifications shown for a
single network id. Given how network notifications are triggered, it can
happen that NO_INTERNET and SIGN_IN notifications are both triggered for
the same network when captive portal detection is slow.
Contrary to the situation before commit 51727428fc, a notification
priority order is introduced so that SIGN_IN always overrides
NO_INTERNET, and NO_INTERNET is ignored if SIGN_IN is already present.

Always-on VPN is a feature introduced in N. Since then, all VPN apps
targeting N+ are assumed to support the feature, and the user or the DPC
can turn on / off always-on for any such VPN app. However, a few VPN
apps are not designed to support the always-on feature. Enabling
always-on for these apps will result in undefined behavior and confusing
"Always-on VPN disconnected" notification.
This feature provides a new manifest meta-data field through which a VPN
app can opt out of the always-on feature explicitly. This will stop the
always-on feature from being enabled for the app, both by the user and
by the DPC, and will clear its existing always-on state.
A @hide API is provided to check whether an app supports always-on VPN.
Documentation is updated to reflect the behavior change.

For a long time we've had a nasty tangled dependency between Wi-Fi
and NPMS, since they both persisted different details for configured
networks. As part of preparing for new carrier data plan APIs, move
the tracking of meteredness over to WifiConfiguration.
This also cleans up how meteredness is communicated through
NetworkAgents to rely completely on NET_CAPABILITY_NOT_METERED by
removing the metered flag on NetworkInfo, which has caused confusion
and staleness.
Migrates any existing user-configured metered networks over to
WifiConfiguration once the device finishes booting.
Remove support for NetworkQuotaInfo, since this information can no
longer be made available to apps. Frustratingly, some apps are
using it, so keep the object around returning stub values, and shame
them in the logs.

This patch adds a InitialConfiguration class to IpManager for specifying
IP information in IpManager ProvisioningConfiguration at IpManager
startup.
At the moment this InitialConfiguration is not used, but is validated in
startProvsiioning if ProvisioningConfiguration includes one. It will be
integrated into IpManager IP provisioning logic in follow-up patches.
This patch also includes an example of data driven unit tests using a
table of test case. The highlights of this methodology are:
1) easy extensibility for new test case,
2) rich and informative error messages,
Unfortunately Java support for inlined data structure literals is poor
and some companion static methods for data generation are required for
enabling this methodology.
