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.

Since the Framework net test require jni library
libnetworkstatsfactorytestjni, but the test fails to load that library
unless *all* the dependencies of that library are explicitly listed in
jni_libs, whenever any of the dependencies changes the framework net
test will start failing and it might not be catched since the change
might not related to frameworks/base. And this smoke test is aimed to
spot those native library changes and it should be stable enough to put
in global presubmit.

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.

Carriers in Mainland China need to customize certain captive portal
urls. The main issue is that google servers are not accessible in
Mainland China.
Added the following captive portal resources to be targeted for overlay.
- config_captive_portal_http_url
- config_captive_portal_https_url
- config_captive_portal_fallback_urls (string-array)
- config_captive_portal_fallback_probe_specs (string-array)
These values can be customized for e g diffent countries

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.

This commit reduces the flakiness of the

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 SocketUtils.attach*Filter and SocketUtils.addArpEntry methods
were added there because they could not be added as JNI inside
the NetworkStack. This was not possible because on Go devices,
the NetworkStack was a jar library. But now, Go also uses an APK.
Hence, move these methods to the NetworkStack.

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.

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.
