The mLockdownEnabled boolean and the mLockdownTracker objects are read
and mutated in many places involving vpn logic inside of
ConnectivityService. This includes codepaths run on the
ConnectivityService handler and codepaths run on Binder calls from
IConnectivityManager.aidl, however the access to these variables are not
synchronized.
This patch adds proper synchronization to mLockdownEnabled and
mLockdownTracker by moving access to them into the mVpns lock used for
all of vpn logic.

This patch fixes a regression introduced by commit d5c11bbb65
for logging NetworkEvents when lingering and unlingering a network.
Commit d5c11bbb65 removed an overloaded constructor for the
NetworkEvent class, which caused NetworkEvents with event type of
LINGER or UNLINGER logged in ConnectivityService to have incorrect
event types (set to the network id instead) and incorrect duration
(set as the event type instead).

This patch changes instrumentation of default networks and default
network events:
- stop logging events for default network transitions,
but instead consistently log one event per continuous segment
when one given network was the default, including logging an
event for when there is no default network.
- keep a separate rolling buffer of DefaultNetworkEvent for
dumpsys and bug reports.
These changes allow to simplify post aggregation of default network
event metrics by removing any need to do time series processing.
Instead, metrics and counters can be implemented withouth any ambiguity
by following the recipe:
% of x = sum(duration | x = true) / sum (all durations)
where x can be various conditions such as:
- the default network was validated
- the default network was WiFi
- the default network was IPv6
- there was no default network
- ...
Most importantly, this new logging scheme allows to measure much more
reliably:
- the % of the time that a device had Internet, in the sense that the
default network was validated.
- the time transitions between default networks, keyed by previous and
new transports/link layer, which allows to derive wakelock durations
and wakelock power costs from default network switches.
This patch also simplifies the dumpsys interface of the connmetrics
service and reduces the commands to three:
- "flush" for metrics upload.
- "proto" for printing buffered event in text proto format.
- "list" for listing all events and statistics.

The "roaming" state of a network really belongs on NetworkCapabilities
instead of being published through NetworkInfo.isRoaming(). One major
reason is to support developers creating NetworkRequests for a
non-roaming network.
Watch for any capability changes that network statistics are
interested in (either metered or roaming) and notify it to perform
an update pass; fixes bug where we previously only triggered on
roaming changes.
Fix bug in VPNs where metered/roaming capabilities of underlying
networks weren't being propagated; this was probably preventing
some jobs from running over unmetered networks, and causing other
jobs to run over roaming networks! Also passes along link bandwidth
information from underlying networks, and propegates any changes
to underlying networks.
Fix race condition by reading prevNc inside lock. Utility methods
correctly calculate min/max link bandwidth values.

This patch extracts the logging of DefaultNetworkEvent from inside
ConnectivityService and move it to a new DefaultNetworkMetrics class.
The DefaultNetworkMetrics is a singleton owned by the
IpConnectivityMetrics singleton implementing the metrics service for
core networking. ConnectivityService has access to this singleton via
LocalServices.
This class layout will allow to remove the Parcelable interface of
DefaultNetworkEvent and will instead let the IpConnectivityMetrics
service grab metrics from the DefaultNetworkMetrics directly.

On some devices, support for TYPE_ETHERNET is not specified in
the networkAttributes config resource, even though the device is
capable of supporting Ethernet (e.g., via USB host adapters).
This leads to Ethernet working but various connectivity APIs
behaving as if it was not - for example, no CONNECTIVITY_ACTION
broadcasts will be issues when it connects or disconnects.
Ensure that ConnectivityService always treats Ethernet as
available if the service is running. Currently the service is
started if the device supports FEATURE_ETHERNET or
FEATURE_USB_HOST.

This patch implements an outstanding TODO in ConnectivityService to add
synchronization over the map of network request ids to network agent
info objects.
This structure is accessed from multiple threads:
- Binder thread on public aidl methods, most notably via
getDefaultNetwork().
- Internal handler.
This leads to many race conditions that can crash the system server and
reboot the phone if getDefaultNetwork() is called on a Binder thread to
service a public ConnectivityManager api while the default network state
is being updated on the internal handler after losing the default
network.
