2d36831a38 Disable tryCell when UpstreamMonitor stop
tryCell configuration would not be force disabled UpstreamMonitor stop.
If tethering stop with using mobile upstream and swap with SIM fron no
dun to dun supported, dun request would be filed even tethering is not
active.

c94a1ffd55 Update TetheringTests for new connectivity shims
The stable connectivity shims are updated to now contain S API, so
tethering tests that assumed that compatibility R behavior was used need
to be updated.

To avoid such failures Tethering tests should have a test target using
updated shims (TetheringNextTests), but this was not done in S
timeframe.

9c5d40beca Fix TetheringTest crash on eng build
startTrackDefaultNetwork was allowed to called multiple times
before even though there is no one actually do it. However,
in the TetheringTest#verifyDefaultNetworkRequestFiled, a
manual invocation is used to ensure that function supports
multiple entrance.

But with aosp/1697371, startTrackDefaultNetwork is no longer
allowed to be called multiple times, it would lead to log.wtf
and crash system in eng build.

Since the manual invocation of startTrackDefaultNetwork is not
realistic and no longer valid anymore, remove the invocation
that caused the trouble.

a36f33ef90 [SP35] Pass data warning to tethering offload
This is supported by:
  1. Utilize the new API from both NetworkStatsProvider
     and IOffloadControl to send data warning quota to hardware.
     And pass the warning reached notification back to NPMS.
  2. Disable software solution introduced in R release for
     V1.1+ hardware, since now we can fully offload data warning
     and limit notification to hardware.

b95083ea6a No-op Refactoring of startTrackDefaultNetwork
While the actual part that track default request is inside
UpstreamNetworkMonitor, instead of passing it from Tethering,
move it into counter-part CL and use it from
UpstreamNetworkMonitor.

Since the current code is replaced by registerSystemDefaultCallback
in Android S, implement it inside the api30 shim implementation
to provide an unified interface to tethering.

  - IpServerCallback#requestEnableTethering: called by IpServer
    while processing a command.
- setEthernetTethering: only called by enableTetheringInternal.
- EthernetCallback: runs on mExecutor, which posts to mHandler.
- getLastTetherError: only used by the test. Renamed to
  getLastErrorForTest to ensure no other callers.
- sendTetherStateChangedBroadcast: called only by
  notifyInterfaceStateChange, which is called only by
  - IpServerCallback#updateInterfaceState, which is called only
    by sendInterfaceState, which is called by various IpServer
    state enter methods.
- notifyLinkPropertiesChanged: called only by
  IpServerCallback#updateLinkProperties, which is only called by
  IpServer#sendLinkProperties, which is only called by:
  - Code that processes CMD_IPV6_TETHER_UPDATE
  - IpServer#handleNewPrefixRequest: only called when processing
    CMD_NEW_PREFIX_REQUEST.
  - IpServer#sendInterfaceState (see above)

d5096f504d Release mobile request when default upstream is not mobile
Some OEM may have special mobile data icon show up when non-default
(e.g. DUN) mobile connection connected even wifi is also connected.
So always connected DUN may let user hard to distinguish tethering
upstream in those OEM's devices. Also release unused mobile connection
may safe power.

This CL removes unnecessary code from selectPreferredUpstreamType.
In particular:
    - When a DUN or HIPRI upstream is selected, calling
    registerMobileNetworkRequest is unnecessary. A mobile
    NetworkRequest is always registered unless a non-mobile upstream
    is selected.

    - When a non-mobile upstream is found, releasing the mobile
    NetworkRequest is unnecessary in selectPreferredUpstreamType
    because it will be done by chooseUpstreamType immediately after
    selectPreferredUpstreamType returns.

    - When no upstream is found and cellular upstream is not permitted,
    it is not necessary to release the mobile NetworkRequest. When
    cellular is not permitted, no such NetworkRequest will be filed
    because registerMobileNetworkRequest checks with EntitlementManager
    before actually requesting the network. If cellular becomes the
    upstream and then later becomes not permitted because of an
    entitlement failure, all tethering will be stopped by Settings.

Note: currently legacy upstream selection has two known bugs:
1. If mobile has higher priority than non-mobile network, mobile request
should never be released and always prefer use mobile. But in practice,
mobile request would be released when tethering select non-mobile network
as upstream.
2. If mobile has higher priority than wifi network and default network
is wifi but mobile is still connected, tethering would choose mobile as
upstream because it has higher priority. Mobile disconnecting may not
trigger tethering to switch its upstream to wifi because currnetly
tethering rely on CONNECTIVITY_ACTION broadcast to handle upstream
disconnect.

491999292b Fix a race condition in upstream selection.
Current upstream selection code suffers from a race where if the
CONNECTIVITY_ACTION broadcast for a given network switch is
received and processed before the NetworkCallbacks for that
network switch, upstream selection just re-selects the same
upstream it had before. The incorrect upstream persists until
another CONNECTIVITY_ACTION is received.

Fix this by defining a new EVENT_DEFAULT_SWITCHED message code
communicated from UpstreamNetworkMonitor to Tethering, and send
that whenever the default network switches.

The message is sent in onLinkPropertiesChanged, because the
tethering code stores all information about networks in an
UpstreamNetworkState structure that contains Network,
LinkProperties and NetworkCapabilities. When a network switch
occurs, onLinkPropertiesChanged always follows onAvailable and
onCapabilitiesChanged, and thus marks the first point in time
when all the information is available.

This CL tries not to change existing codepaths too much, but
it does move the update of mDefaultInternetNetwork from
onCapabilitiesChanged to onLinkPropertiesChanged. This should
not be a problem because the only thing that reads
mDefaultInternetNetwork is getCurrentPreferredUpstream, which,
in the case of a default network switch, will be run by the
onLinkPropertiesChanged which will immediately follow.

6748e62ef2 Add unit tests for race conditions in upstream selection.
In the current tethering code, upstream selection is only
triggered by CONNECTIVITY_ACTION. But in automatic mode, the
upstream network is selected by listening to a NetworkCallback
that tracks the default network.

This causes a race where if the CONNECTIVITY_ACTION for a network
switch is received and processed before the callbacks for that
network switch, upstream selection just re-selects the upstream
currently in use.

Make it possible to test this by giving TestConnectivityManager
the ability to choose the ordering between NetworkCallbacks and
CONNECTIVITY_ACTION, and to run an arbitrary Runnable between
calling one and calling the other. TetheringTest passes a
Runnable that calls mLooper.dispatchAll(), which ensures that
the tethering code fully processes the first set of information
it receives (either the broadcast (or the callbacks) before
receiving any more information.

Add test coverage to testAutomaticUpstreamSelection that
exercises various orderings, and make the test pass by expecting
the buggy behaviour of the current code.

An upcoming CL will fix the bug and update the tests.

Required because XDP offload needs input interface mac address
to be a part of the key. The mac address is used for checking
packets which are received from exceped input interface.

dc6715c6f8 Set the limit whenever any IPv4 or IPv6 rule exists.
Currently, BpfCoordinator only sets the data limit on a given
upstream whenever the first IPv6 rule is created on that
upstream, and clears it whenever the last rule is deleted on that
upstream. It never does this when adding or removing IPv4 rules.

This makes it impossible to offload traffic on IPv4-only
networks.

Fix this by setting the limit when IPv4 rules are created or
deleted as well.

Test: atest TetheringCoverageTests
Manual tests as the follows
Test {add, clear} limit with IPv6-only network [OK]
Test {add} limit with IPv4-only upstream [OK]

TODO:
Test {clear} limit with IPv4-only network. blocked by aosp/1579873
because the IPv4 rules have never deleted.
