fd8f96d719 Block incoming non-VPN packets to apps under fully-routed VPN
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.

Remi NGUYEN VAN
3962f678c3 Fix race when starting NetworkMonitor
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.

15178155e0 Block unpriviledged apps which create keepalives with null fd
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.

lucaslin
f3b59b3ee0 Fix flaky test for ConnectivityServiceTest#testPartialConnectivity
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.

7c469179ce [KA02.5] Use binder thread and executor to invoke callback
Currently, client side of keepalive event handling rely on a
newly created thread, looper, messenger and handler per object.

However, by creating oneway AIDL interface with the executor,
the callbacks can be invoked on the binder thread with user
specified context, which not only greatly simplify the design
but also reduce the cost of current thread modeling.

05ab6811d0 Tell the factory it is already serving a request.
This is a cherry-pick of ag/607226 that has been rebased on
top of four years of changes and with comments addressed.

Gives each factory a serial number and propagates it to every
NetworkAgent so when a score comes back indicating a request is
being handled the factory can account for it properly.

Without this, a new request that's already handled by a network
offered by a factory will not cause an increment of the factorys
ref count. Concretely this results in issues like the RAT icon
not being displayed in spite of the network actually being up
and usable.

This will be ported to AOSP as soon as possible, but immediately
some master-only WiFi tests need to be adjusted with this change
which would not let me submit to AOSP.

e252a740ca Check if network has partial connectivity
In some networks, network validation may only get success
result for http probe but fail result for https probe.
For this kind of network, it may still work at some websites

notify user to make a choice if they want to use this partial
connectivity or not.

ddb720a85e [CS] Support "instant failure" from factories
Add a mechanism by which a factory can declare "instant failure" for
a request - which would result in it getting an OnUnavailable()

Factories may only do this iff:
1. They know they are the only factory which may fulfill this
   request (common for transport-specific requests).
2. The know that the request can definitely not be
   fulfilled at any point in the future.

d33cbc6f5f Remove ConnectivityManager and its usages from NetworkStatsService.
NSS needed it for getting VpnInfo[], NetworkState[] and
activeLinkProperties which it used to query via ConnectivityManager.

For VpnInfo[], this was racy as NSS may ignore intermediate changes to a
VPN's underlying networks. See http://b/123961098 for more context.

It may also lead to deadlocks b/w ConnectivityService and
NetworkStatsService. See http://b/126245192 for more info.

This change will ensure that NSS is never contending on any of
ConnectivityService locks.

c51b06d276 Fix isActiveNetworkMetered for VPNs.
This change is basically a revert of http://ag/3580901.
It was made because previously VPN capabilities did not use to update
based on its underlying networks. That is no longer the case anymore.

This was previously returning meteredness on the basis of VPN's first
underlying network which is incorrect in cases such as VPN using
multiple underlying networks, or VPN that has explicitly marked itself
as metered via VpnService.Builder#setMetered API.

d593e298c6 Manage NAT64 prefix discovery lifecycle in the framework.
Currently NAT64 prefix discovery, which runs in netd, is started
by netd itself when a network is programmed with all-IPv6 DNS
servers. Unfortunately this is not correct because in many cases
we program DNS servers before the network is connected and it's
actually possible to send packets to them.

In general netd does not have enough visibility into network
lifecycle management to decide when to start and stop prefix
discovery. So move it into the framework with the rest of the
464xlat control plane.

6998fa8a17 Track NAT64 in the framework and start clatd iff NAT64 detected
Currently, both netd and clatd do NAT64 prefix detection, and we
start clatd on all IPv6-only networks regardless of whether netd
has detected a NAT64 prefix or not.

Instead, track the NAT64 prefix in the framework, and only start
clatd if the prefix is detected. This will allow us to remove
DNS64 detection in clatd, and pass the NAT64 prefix and the IPv6
address to clatd on the command line instead of clatd finding it
itself. That way, netd and the framework will always know how
464xlat is configured, and we'll be able to use that information
in netd.

4fa80e8a2f Update VPN capabilities when its underlying network set is null.
Previously, they were only updated when underlying network set was
non-null.

This change also ensures that all the calls b/w ConnectivityService and
Vpn that leads to updating capabilities are on ConnectivityService
handler thread.

Additionally, it also ensures that capabilities are propagated after VPN
enters connected state. This was previously done from establish which
could potentially lead to race between VPN getting connected and
capabilities getting updated.

This change also updates VPN capabilities inline from
ConnectivityService handler thread. Previously, there was an additional
loop where Vpn would update capabilities via NetworkAgent thru
AsyncChannel which posts back to CS handler thread, which could
potentially lead to delays in updating VPN capabilities.
