bf737c0a6b Extract RingBuffer class from NetdEventListenerService
This patch takes out the ring buffer array added for NFLOG wakeup packet
events logging and extract it into its own class for reuse. This new
RingBuffer class has the two minimal useful functions append() and
toArray().

53e6fd54e6 Implement ConnectivityService TODO and fix many race conditions
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.

3c15d11b94 Connectivity metrics: add WakeupStats events
This patch defines a new WakeupStats event in ipconnectivity.proto and
populates these events from the NFLOG wakeup events stored in
NetdEventListenerService.

There is one WakeupStats object per known interface on which ingress
packets arrive and may wake the system up.

Example from $ adb shell dumpsys connmetrics list:

UPDATEME

738a0a48ab Opt-out for always-on VPN
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.

ffd77d8f29 Always add local subnet routes to the interface's routing table
For some networks such as mobile data connections, its LinkProperties
does not contain routes for the local subnet so no such route is added
to the interface's routing table. This can be problematic especially
if the device is in VPN lockdown mode where there exists high-priority
PROHIBIT routing rule which in turn blocks the network's default gateway
route from being added (next hop address hitting the prohibit rule).

We fix this by patching LinkProperties to always include direct connected routes
when they are received by ConnectivityService. This has the added advantage that
when apps get LinkProperties, they see the directly connected routes as well.

Bug: 63662962
Test: runtest frameworks-core -c android.net.LinkPropertiesTest
Test: runtest frameworks-services -c com.android.server.ConnectivityServiceTest
Test: Start with device with mobile data, set up ics-OpenVPN in always-on
      lockdown mode. Turn off mobile data then turn it back on, observe
      mobile data connectivity is restored and VPN successfully reconnects.

9d35b759e5 Nat464Xlat: correct racefree teardown
This patch relays the NetworkBaseObserver notifications about nat
464xlat stacked interfaces onto the ConnectivityService handler.

This allows to process interface up and down notifications in the
same thread context and eliminates several races:

  - NPE risk due to race between fixupLinkProperties called on
    ConnectivityService thread and interfaceRemoved called on
    NetworkManagementService thread.
  - stale LinkProperties pointer reads in both NetworkBaseObserver
    callbacks not called on ConnectivityService handler.
  - removes the race between stop() and interfaceRemoved().
  - removes superfluous LinkProperties notifications when stop() is
    called before the stacked interface goes up.

The teardown procedure logic common to stop() and interfaceRemoved() is
put into enterStoppedState() and enterIdleState().

This allows to distinguish and correctly handle the following teardown
scenarios:
 - an IPv4 appears -> ConnectivityService calls Nat464Xlat#stop()
                   -> Nat464Xlat calls stopClatd
                   -> clatd stops
                   -> if the stacked interface was up, it is removed
                   -> Nat464Xlat#interfaceRemoved() is triggered and
                      a LinkProperties update is sent.

 - network disconnects -> ConnectivityService calls Nat464Xlat#stop()
                       -> Nat464Xlat calls stopClatd
                       -> clatd stops
                       -> if the stacked interface was up, it is removed
                       -> Nat464Xlat#interfaceRemoved() is triggered and
                          a LinkProperties update is sent.

 - clatd crashes or exit -> Nat464Xlat#interfaceRemoved() is triggered
                         -> Nat464Xlat unregisters itself as a network
                            observer
                         -> ConnectivityService is updated about the
                            stacked interface missing, and restarts
                            Nat464Xlat if needed.

Note that the first two scenarios have two cases: stop() can be called
before the notification for the stacked interface going up (STARTED), or
after (RUNNING). In the first case, Nat464Xlat must unregister
immediately as a network observer to avoid leaks.

This patch also:
  - removes/simplifies comments related to the threading model which
    are no obsolete.
  - extract clatd management logic from ConnectivityService into
    NetworkAgentInfo
  - add new unit tests where there was none before.
