243301748e Write Data Saver setting to BPF map
The information is needed by modules who want to know whether a
specific UID is blocked by Data Saver feature.

1. Add a one-element map data_saver_enabled_map.
2. Update current data saver setting to the map.

6b134f18f4 Pass NetworkCapabilities into DnsManager
1. At present, the transportTypes in NetworkCapabilities have been
passed into DnsManager::updateTransportsForNetwork() as a parameter. In
the following CL, we also need to pass the 'metered' (also in
NetworkCapabilities) as a parameter to the function. Instead of passing
the members of NetworkCapabilities one by one, it is better to pass the
entire NetworkCapabilities.

2. Rename updateTransportsForNetwork() to
updateCapabilitiesForNetwork().

This reverts commit 55ccfe19e2.

Reason for revert: this must be introducing some sort of race
it appears to cause
  atest EthernetTetheringTest 'NetdBinderTest#TetherForwardAddRemove'

49f7ab9eeb Fill ConnectivityService in testDumpDoesNotCrash()
testDumpDoesNotCrash does not dump enough objects to have full
coverage. e.g. In b/303348620, it did not detect the crash since
there is no NetworkAgentInfo stored in ConnectivityService.

This change ensures ConnectivityService is filled with more
objects that will be dumped:
1. NetworkProvider
2. NetworkAgentInfo
3. NetworkOffer
4. Network preferences

We can always revert if it ever turns out this is useful,
but I'd prefer for cgroup attach to be a once-at-boot
thing and handled either from bpfloader or the netd updatable
which are both directly C++ code.

41b37349f3 Support NetworkStatsEventLogger
The performPoll method in the NetworkStatsService can be called
for many reasons, such as RAT changed events, LinkProperties
changed events, open session method calls, forceUpdate method
calls, etc.
However, the current logging is not sufficient to trace down
the caller of performPoll. This makes it difficult to debug
frequent poll issues or performance problems.

Adding debug log to logcat is not an option, given that
performPoll might run several times per second by system server
callers.

This change adds a reason code to the performPoll method and
a helper class to log performPoll events. This will allow us
to track down the caller of performPoll and better understand
why it is being called frequently or causing performance
problems.

This change also introduces a PollEvent object, which can be
used to put related information in subsequent changes when
logging.

Sample output:
Poll counts per reason:
  DUMPSYS: 0
  FORCE_UPDATE: 6
  GLOBAL_ALERT: 0
  NETWORK_STATUS_CHANGED: 3
  OPEN_SESSION: 0
  PERIODIC: 1
  RAT_CHANGED: 1
  REG_CALLBACK: 3
  REMOVE_UIDS: 0
  UPSTREAM_CHANGED: 1

Recent poll events:
  2023-10-04T02:47:12.937370 - Poll(flags=3, PollEvent{reason=REG_CALLBACK})
  2023-10-04T02:47:13.178559 - Poll(flags=3, PollEvent{reason=FORCE_UPDATE})

626045a601 [BR01.1] Support BpfNetMapsReader
A helper class to *read* java BpfMaps. This is designed to
provide direct bpf access in the caller process through
ConnectivityManager APIs.

The change also removes any statical link to
net-utils-device-common-struct from service-connectivity.
This is because net-utils-device-common-struct is already
included in framework-connectivity. Including it again in
service-connectivity would create a r8 build fail by circular
dependency.

f3fe3333d3 Add expired services removal flag
The TTL check and removal of expired services is currently only
performed when a mDNS query is sent. This can result in expired
services remaining in the cache if no queries are sent. To
address this, the remaining TTL will be checked when retrieving
services from the MdnsServiceCache. Add a new flag to enable
the expired services removal feature. This feature will be
implemented in subsequent changes.

f8dba342f1 Move dumpsys to handler thread
I0afdda023208c3f8620cb5b89add66448af596d7 added some assertions
to ensure NetworkAgentInfo can only be accessed from the handler
thread. This is good to eliminate any potential concurrent
accessing problem. Howver, dumpsys runs on binder thread, this
change breaks dumpsys functionality.

Thus, this change:
  1. Copy Handler#runWithScissors() and related class
     locally since they are @hide methods.
  2. Run doDump on the handler thread and waits for return.

774dc3cd51 Tell netd about local networks
This patch does the following :
• When a network is local but the system doesn't support it,
  throw in registerNetworkAgent.
• When a network is local, tell netd about it.
• Add tests for the above, as well as a test for callbacks
  being sent correctly when the caps are set and not when
  they aren't and that the new keep connected flag is
  respected.

Telling netd about the network being local has it add two
routes that do not exist if the network is not local :
• One at PRIORITY_LOCAL_NETWORK matching unmarked sockets
  and looking up the table for the interface.
20000: from all fwmark 0x0/0x10000 lookup xxxx
• One at PRIORITY_EXPLICIT_NETWORK matching explicitly on
  network 99, so that dnsmasq traffic and any OEM traffic
  marked for network 99 flowing there.
16000: from all fwmark 0x10063/0x1ffff iif lo lookup xxxx
IMPLICIT_NETWORK and EXPLICIT_NETWORK rules are installed
by connectivity service as a matter of course whether the
network is local or not.

See commit If8729fc6f3716a580c936584b851bc38000b5de5 for
implementation details of this mechanic.

There is no need to implement anything in particular for the
new connected reason, as the current implementation will
already keep it connected. A new test makes sure of that.

ed972a6fd2 Ensure nri is satisfied before returning.
When a network preference is set, the highest priority nri will
be a managed default request that disallows default networking.
In the case where there is no satisfying network,
mNoServiceNetwork is used as the satisfier instead of null.
(see computeNetworkReassignment)

mNoServiceNetwork should not be returned in any public API.
Check for the nri being satisfied before returning the satisfier
to ensure mNoServiceNetwork is not returned.
