cecd4a3d64 [KA11] Verify fd ownership and allocate resource for NattKeepalive
Since socket keepalive APIs for UDP encapsulation sockets are
public to generic app. In order to ensure the given fd is valid,
this change verifies the resource id inside the UDP
encapsulation socket by using methods provided by IpSecService.

3394e14fc3 Tethering: fix using wrong subId problem
There is the potential bug[1] that default data subId change
intent may lose. So tethering may cache the outdated default
data subId in TetheringConfiguration. Now EntitlementManager
would fetch configuration every time and this would re-exam
whether subId is changed.
Additional passing subId to Settings to avoid default data
subId change right away when launching entitlement check.
Thus, Settings can know whether this is outdated entitlement
check request.

0535295bb9 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.

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.

ccfaa3c06d Fix remove-before-add for IpSecService RefcountedResource
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.

f2f1f27098 Move NetworkStatsFactory into service directory
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.

a6817cd532 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.

NetworkMonitor obtained LinkProperties and NetworkCapabilities via

29d2ef2fe1 NetworkStatsService: Fix getDetailedUidStats to take VPNs into account.
This API is similar to one provided by NetworkStatsFactory with the
difference that NSS also migrates traffic from VPN UID to other apps.

Since traffic can only be migrated over NetworkStats delta, NSS
therefore maintains NetworkStats snapshot across all UIDs/ifaces/tags.

This snapshot gets updated whenever NSS records a new snapshot
(based on various hooks such as VPN updating its underlying networks,
network getting lost, etc.), or getDetailedUidStats API is invoked by
one of its callers.

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.
