This patch removes from ConnectivityService the logic involved in
deciding if a uid has access to networking based on networking policies.
This logic is moved into NetworkPolicyManagerService which is the source
of truth with regards to the state of networking policie, both for
existing networks and uids.
Instead ConnectivityService directly queries NetworkPolicyManagerService
in a synchronous fashion for a specific uid or a (uid, network) pair.
This eliminates the need to keep a copy of the uid policy rules inside
ConnectivityService and ensures that ConnectivityService takes
networking decisions based on the correct state of networking policies,
and therefore eliminates certain data races in ConnectivityManager API
that applications are exposed to.

This cleanup helps declutter ConnectivityService, and encapsulates the
always-on setting inside of Vpn instead of spreading it across two
classes.
In particular having the save code in one file and the load code in
another file was weird and I apologise for that.
Added a SystemServices wrapper for Settings.Secure and PendingIntent
calls to decouple some of the global state nastiness and make it
testable without forcing ConnectivityService to drive the load/save.

Change-Id: Ie2adb1c377adfcef0a5900dc866e6118f451b265
The testNotificationsShownAndCleared test was not doing anything
because the list of notification to show was always empty.
This patch fixes this issue and actually makes the test loop on
non-empty collections, and also fixes another ordering issue in
assertions themselves, hidden until now by the first issue.

This patch adds transports info to ValidationProbeEvent and migrates
netId logging for this event to the topt-level netId field in
ConnectivityMetricsEvent.
Test: modified unit tests. $ runtest frameworks-net passes
Bug: 3490169
Change-Id: Ibf51049ba8901ae5ca4ea86e2f500944a4738b5c
This patch deprecates the ifname field for specific metrics events of
types DhcpClientEvent, DhcpErrorEvent, IpReachabilityEvent and
IpManagerEvent.
Instead ifnames are logged in ConnectivityMetricsEvent, allowing for
link layer inference.
Test: updated unit tests, $ runtest frameworks-net passes
Bug: 34901696
Change-Id: I8bfabcb115bbd5289471d653c153a40bb48f28cd
This patch adds translation from ConnectivityMetricsEvent to
IpConnectivityEvent of recently added fields:
- top-level network id
- top-level ifname
- transports
Also adds inference of link layer from transports or ifname.
At the moment these new fields are not populated in
ConnectivityMetricsEvent. Follow-up patches will fill this gap for
the events of the android.net.metrics package.
Test: new unit tests, $ runtest frameworks-net passes
Bug: 34901696
Change-Id: I563a6a3183470bdfaabb7c781a1beaf6b1058bf0
This patch adds new fields to ConnectivityMetricsEvent to make it more
symmetric to IpConnectivityEvent in ipconnectivity.proto.
Follow-up patches will start populating these fields for users of
IpConnectivityLog.
Test: unit tests updated, $ runtest frameworks-net passes

Change-Id: I396767cdfcf38cce893c0d6e1f4524f12e3fdc64
Now that ConnectivityMetricsEvent is only used for core networking
metrics and is not @SystemApi anymore, remove unused fields and prepare
for additional new fields.

This patch adds a few missing counters to APF events:
- an actual lifetime duration to ApfProgramEvent.
- counters for total number of updates to ApfStatistics.
ApfProgramEvents are now recorded at program removal in order to
populate the actual lifetime of the program. ApfProgramEvents whose
actual lifetime was less than 1 second are filtered out.
Finally, instance fields of ApfProgramEvent and ApfStats classes are
made mutable to allow for simple record-like creation. This was not
possible when these classes were tagged @SystemApi.
Test: - manually verified output of $ dumpsys connmetrics list
- unit tests updated.

This patch:
- adds a counter to ConnectStats for counting the number of successful
connect() calls done in blocking mode. This allows to compute error
rates for connect() in blocking mode.
- add printing of ConnectStats when dumping NetdEventListenerService
and/or IpConnectivityMetrics service.
Test: $ runtest frameworks-net, + manual tests verifying logged events.

- whether the network is currently suspended
Additionally:
- Rename notifyNetworkCallback() to notifyNetworkAvailable()
in order to clarify its real function.

This patch cleans obsolete code related to IP connectivity metrics:
- remove @SystemApi on android.net.metrics: now that metrics events
are processed and serialized in the frameworks only, event classes
should not appear in the system apis.
- remove obsolete Logger classes: ConnectivityMetrics app was the
unique user of ConnectivityMetricsLogger until nyc-mr1. From nyc-mr1
the app started using dumpsys to get metrics for IpConnectivity and
Telephony, which made ConnectivityMetricsLogger obsolete.
- simplifications in MetricsTestUtil
Test: - runtest frameworks-net
- manually verified $ adb shell dumpsys connmetrics

This allows an application that knows how to provide seamless
network connectivity (e.g., using QUIC multipath) to find out if
doing so is desired.

Thread.sleep() are in the tests that check for NetworkRequest
timeouts.

The calls in testAvoidBadWifi are no longer necessary now that
waitForIdle is reliable, and the calls in testPacketKeepalives
are replaced with a wait for the NetworkAgent to disconnect.

Rename the class and ensure that all code related to bad wifi
avoidance has names that reflect its purpose. This will allow us
to reuse most of the the code for other purposes in future CLs.
