fd850fd3eb Release keepalive slot after stopped
Currntly, keepalive slot is released when stop() is called. Next
starting keepalive can use the same slot number while previous
keepalive is still stopping. When the previous keepalive is
stopped, the incoming as will be processed by the new keepalive.

This change release keepalive slot after the result of stopping
has returned. Thus, newly created keepalive cannot allocate the
same slot number while lower layer is still processing stop event.

This change also disable flaky assertions that are caused by
test port has been occupied by other process.

f98611062c Support strict mode private DNS on VPNs that provide Internet.
Currently, strict mode private DNS does not work on VPNs because
NetworkMonitor does not validate VPNs. When a VPN connects, it
immediately transitions to ValidatedState, skipping private DNS
hostname resolution.

This change makes NetworkMonitor perform private DNS hostname
resolution and evaluation even on VPNs.

In order to ensure that the system always immediately switches to
the VPN as soon as it connects, remove the unvalidated penalty
for VPN networks. This ensures that the VPN score is always 101
and the VPN always outscores other networks as soon as it
connects. Previously, it would only outscore other networks
when no-op validation completed.

5acedecaee [CS] Unregister callback as part of onUnavailable dispatch
The onUnavailable semantics promise that it is equivalent to calling
the unregister callback method. But - it doesn't unregister the callback
allowing it to be reused. Fixed.

Additionally, modified the unregisterNetworkCallback method to not fail
on duplicate unregistration (since a callback could now self
unregister). Instead simply print a log.

9a3f724597 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.

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.

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.
