When a fully-routed VPN is running, we want to prevent normal apps
under the VPN from receiving packets originating from any local non-VPN
interfaces. This is achieved by using eBPF to create a per-UID input
interface whitelist and populate the whitelist such that all
non-bypassable apps under a VPN can only receive packets from the VPN's
TUN interface (and loopback implicitly)
This is the framework part of the change that build the whitelist.
The whitelist needs to be updated in the following cases:
* When a VPN is connected and disconnected
This will cover the change to allowBypass bit, since that can't be
changed without reconnecting.
* When a VPN's NetworkCapabilites is changed (whitelist/blacklist app changes)
* When a new app is installed
* When an existing app is removed
* When a VPN becomes fully-routed or is no longer fully-routed
New user/profile creation will automatically result in a whitelist app change
transition so it doesn't need to be handled specially here.
Due to the limitation of the kernel IPSec interacting with eBPF (sk_buf->ifindex
does not point to the virtual tunnel interface for kernel IPSec), the whitelist
will only apply to app VPNs but not legacy VPN connections, to prevent breaking
connectivity with kernel IPSec entirely.

This patch fixes a bug where if a binder dies before the linkToDeath
call, the cleanup will be performed before the entry is added to the
array. While it is safe in that quotas and tracking performs as per
normal, the RefcountedRecord may not be cleaned up.
Rethrowing this exception is safe, since the only paths that would hit
this are all on binder threads coming from applications. Further, it
seems there is only one real way of this getting hit - if the app that
called the creation died during the binder call.

In order to notify netd to swap eBPF maps before pulling the
networkStats from eBPF maps, NetworkStatsFactory need to use the
NetdServices to issue binder calls. So it need to be moved from
framework/base/core to framework/base/service since object in
framework/base/core cannot get any system services. This change is also
necessary for setting up a lock inside NetworkStatsFactory to prevent
racing between two netstats caller since the lock need to be hold before
netd trigger the map swap.
Also fix the compile problem caused by moving the NetworkStatsFactory
and the related tests. Rename the packages and the jni functions to a
more proper name.

The kernel eBPF maps have a blacklist to store all the uids that doesn't
have internet permission. When an app is unintalled from the device and
it is the last package on device that uses that uid, make sure we
cleaned the uid from the map and do not add no longer used uids into the
eBPF map. This action helps reduce the number of entries stored in the
map and reduce the chance of overflow the eBPF map.

Fix: 129097486
Test: atest FrameworksNetTests
NetworkMonitor obtained LinkProperties and NetworkCapabilities via
synchronous calls to ConnectivityManager after receiving an asynchronous
notification, which is prone to races: the network could be gone before
the LinkProperties/NetworkCapabilities can be fetched.
Fix the race by passing LinkProperties/NetworkCapabilities directly to
NetworkMonitor in the asynchronous notifications.

* changes:
Move BatteryStats and StatsCompanionService to use NetworkStatsService.
NetworkStatsService: Fix getDetailedUidStats to take VPNs into account.
Take all VPN underlying networks into account when migrating traffic for VPN uid.
This API is similar to one provided by NetworkStatsFactory with the
difference that NSS also migrates traffic from VPN UID to other apps.
Since traffic can only be migrated over NetworkStats delta, NSS
therefore maintains NetworkStats snapshot across all UIDs/ifaces/tags.
This snapshot gets updated whenever NSS records a new snapshot
(based on various hooks such as VPN updating its underlying networks,
network getting lost, etc.), or getDetailedUidStats API is invoked by
one of its callers.

Currently, socketKeepalive implementation is accepting null fd
due to backward compatibility with legacy packet keepalive API.
However, due to lack of the fd, the service cannot guarantee the
port is not reused by another app if the caller release the port
for any reason.
Thus, grant the null fd access only for priviledged apps.
This commit also address some comments from aosp/918533.

There are 2 problems will make testPartialConnectivity flaky:
1. If we call setNetworkValid() before expectCapabilitiesWith(),
there may be a timing issue that network will become VALID before
NetworkMonitor send PARTIAL_CONNECTIVITY to ConnectivityService.
Solution:
We should set network to valid after ConnectivityService received
NETWORK_TEST_RESULT_PARTIAL_CONNECTIVITY to ensure NetworkMonitor
will send PARTIAL_CONNECTIVITY to ConnectivityService first then
send VALID.
2. When test case call explicitlySelected(true) first then call
connect(true), NetworkMonitor will report the network validation
test result twice because ConnectivityServiceTest() will trigger
notifyNetworkTested() when setAcceptPartialConnectivity() is
called, it may cause a timing that before the second test result
send to ConnectivityService, connect() already called
setNetworkInvalid. So, NET_CAPABILITY_VALIDATED will be removed
and ConnectivityService will trigger onCapabilitiesChanged()
unexpectedly.
Solution:
Don't trigger notifyNetworkTested() when
setAcceptPartialConnectivity() is called. If there is needed,
use mCm.reportNetworkConnectivity() to report the test result
instead.
