75387c9ced Update multiple validation result to ConnectivityService
Once a network is determined to have partial connectivity, it
cannot go back to full connectivity without a disconnect. This
is because NetworkMonitor can only communicate either
PARTIAL_CONNECTIVITY or VALID, but not both. Thus, multiple
validation results allow ConnectivityService to know the real
network status.

Remove definition of TYPE_NATT and TYPE_TCP since the type

NattKeepalivePacketData or TcpKeepalivePacketData.
It's more simple and won't have dependency on KeepaliveInfo.

24bd38cc20 Clean up the keepalive slots when network disconnect
In general, keepalive slots are released after result of
stopping has returned. However, for network disconnect case,
the service side cannot communicate with network agent since
the async channel is broken.

7d960da6ff 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.

caefc43336 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.

a83c9f38a6 Clean up the keepalive slots when network disconnect
In general, keepalive slots are released after result of
stopping has returned. However, for network disconnect case,
the service side cannot communicate with network agent since
the async channel is broken.

Clean up keepalive slots right after stop in this case.

1f8bf657bb Limit unprivileged keepalives per uid
Public APIs for creating unprivileged NATT socket keepalive
might allow users to exhaust resource if malicious apps try
to create keepalives with fd which is not created by
IpSecService through binder call. Thus, this change add
customizable limitation per uid to prevent resource exhaustion
attack.

5218015ed8 Revert "[KA11] Verify fd ownership and allocate resource for NattKeepalive"
This reverts commit 8368fe9fe0.

Reason for revert: Adds dependency between IpSecService and
                   ConnectivityService may lead to future deadlock
                   problems. Uses a simpler approach instead,
                   hence the solution is not needed.
                   See aosp/954040.
