37033fd067 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.

1c19cf383f 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.

6d761f9007 Extend support for requestRouteToHostAddress for backward compatibility
The gnss@2.0 HAL and the framework GNSS Location Provider code is
updated in Q to not call the deprecated requestRouteToHost() method.
However, devices upgrading to Q which are still using gnss@1.1 or
earlier HAL must continued to be supported.

Fixes: 121222025
Test: Tested with gnss@1.1 HAL and first API level P.  The
      ConnectivityService log message "This method exists only for
      app backwards compatibility and must not be called by system
      services" is not present for devices with first API level P.

b2d1084807 Fix NetworkMonitor won't do private dns resolution
NetworkMonitor cannot do the private dns resolution due to lack
"mNetworkCapabilities". ConnectivityService will call
NetworkStackService#notifyPrivateDnsChanged() before doing
network validation. After NetworkMonitor received
CMD_PRIVATE_DNS_SETTINGS_CHANGED, it will call
isValidationRequired to check if the validation is required.
But mNetworkCapabilities didn't be set, so the
mPrivateDnsProviderHostname will be set to empty and make
EvaluatingPrivateDnsState doesn't do private dns resolution.

092d3a5997 Clean up permissions when uids are no longer used
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.

71d379fe89 Ignore the asynchronous result while stopping keepalive
Currently, onStopped callback are synchronizely triggered when
stop() was called, since the framework don't really care
about the result of stopping keepalive.

However, if keepalive failed to stop for some reason, the
handleStopKeepalive was called mistakenly and trigger additional
callback that fail the test case.

This commit is the behavior change prior to state machine
refactoring, and introduce a stopping state for ignoring the
result in the stopping state.

b1b282c8ee Cleanup SystemReady in the network stack
The system server (in SystemServer.java) defines the boot
sequence, during which an event called SystemReady happens.
This corresponds to a time when critical system services
that are depended upon by other components in the system
server are ready to handle requests from their dependencies.
Some system services are listening to this event to defer
initializations that depend on the critical services.

Because the network stack is only started after SystemReady,
there is no way any NetworkMonitor may be started before
SystemReady. Remove the associated mechanism.

f59a5d4580 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.

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.
