(mostly to improve code coverage)
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.

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})

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.

Calls to setRequireVpnForUids() for Vpn lockdown actually uses a

Add intRangesExcludingUids() to return the needed List of integer
ranges and replace relevant usages of UidRange.toIntRanges() with
it.

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.

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.

- To simplify the design, pass the CacheKey to MdnsServiceCache

This doesn't do anything at this patchset, but the whole
pipe from the agent to ConnectivityService is built.
LocalNetworkInfo will be the name of the public information
sent in callbacks to clients.
Test: CSLocalAgentTests
Change-Id: I70e133031ef3b0aaf6c3e59ccc2ad895c66d339c
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.

* changes:
Ensure nri is satisfied before returning.
Add testLockdownVpn that mocks platform VPN.
Make variables in testLegacyLockdownVpn() final.
Update testLegacyLockdownVpn to mock VPN.
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.

Add a test for lockdown vpn that uses TYPE_IKEV2_IPSEC_PSK and
mocks platform VPN by override in startLegacyVpnPrivileged().
In the context of ConnectivityService, setVpnDefaultForUids()
is the main interaction.
Refactor testLegacyLockdownVpn to take a VpnProfile and assert
behaviors with and without setVpnDefaultForUids().
This includes:
1. Updating callback asserts and assertActiveNetworkInfo to
reflect setVpnDefaultForUids().
2. Adding TODOs where mCm.getActiveNetworkInfo() returns
unexpected values.

The created handler thread will stay there for a while until
all the tests are finished. This is considered as a leakage
which will take the resource from the devices. In low end
devices, this may possibly impact the performance. The created

Improvements to CSTest : legacy type, wait for LOST, permissions
This has been sorely needed for a while. Instead of filing requests
for each of your networks in a CSTest, which is fiddly at best and
sometimes almost impossible (because you can't single out the network),
you can now add this flag and be done with it.

• Make sure all Agents have a legacy type. This is necessary to
avoid crashes in LegacyNetworkTracker
• Wait for LOST when disconnecting a network
• Make sure the test package sees its own permissions (importantly
it can't see background networks otherwise, because it lacks
CHANGE_NETWORKING_STATE)
