Change the permission check for tethering to checkPackage. This avoids

This change addresses the launch of entitlement UI activities
in Headless System User Mode (HSUM) on multi-user devices.
HSUM is a configuration where the system user (user 0) does
not represent a human user and primarily runs system services.
In this mode, the first user set up on the device is not user 0.
Modified the EntitlementManager logic to handle the
launch of the entitlement UI in multi-user environments,
specifically addressing scenarios where HSUM is enabled, which
includes:
1. Always launch the UI to the foreground current user.
2. Check whether the current user is allowed to show the UI.
This ensures the UI is presented to the appropriate user.
Test: Manual
1. Mock requires entitlement
2. adb shell cmd user set-system-user-mode-emulation headless

This CL splits requestDownstreamAddress into two methods: requestStickyDownstreamAddress and requestDownstreamAddress.
- The requestStickyDownstreamAddress is equivalent to the former requestDownstreamAddress when useLastAddress=true.
- The new requestDownstreamAddress method allows allocating an address without providing the interface type and scope, which is Thread NAT64's use case.

PrivateAddressCoordinator: move the special handling of WiFi P2P dedicated IP to IpServer
Treehugger Robotauthored and Gerrit Code Reviewcommited 2024-10-08 17:07:29 +00:00
This CL introduces the Dependencies class for PrivateAddressCoordinator
to allow changing the TetheringConfiguration in tests. Although in
production code TetheringConfiguration won't change after passed to
PrivateAddressCoordinator, there are unit test cases relying on changing
the configuration at runtime.

dedicated IP to IpServer
The source of
TetheringConfiguration#shouldEnableWifiP2pDedicatedIp is in the
Tethering's resources. As refactoring the code, we noticed that it will
be simpler to handle this at IpServer (constructed using
TetheringConfiguration) instead of at PrivateAddressCoordinator
(will require reflection to read the Tethering's resources).

TetheringMetrics creates a thread to process all metrics work on
a handler. This thread should remain active alongside the
Tethering service but should be closed in test class. Therefore,
add MonitorThreadLeak to ensure the thread is closed correctly.

The previous implementation for tracking tethering active sessions
was overly complex. This commit simplifies the logic by:
- Moving the counting to the BpfCoordinatorShimImpl (31 impl)
where rule addition and deletion are centralized.
- Eliminating the unnecessary Android version check (S+) as
the 31 shim only runs on S+.
- Relocating the tracking counters from
ConntrackEventConsumer to the shim class, improving code
locality and encapsulation.
This change addresses the feedback from the networking mainline
release council and resolves a release blocker.

This removes all the complex downstream prefix / address selection
logic and reduces it to generating a random address within the selected
prefix and checking whether it satisfies a set of conditions. If the
conditions are not met, the process is retried (for a total of 10 times)
before eventually moving on to the next prefix.
The conditions that must be satisfied are:
- Address within prefix does not end in .0, .1, .255
- Address is not contained within a range of commonly used prefixes.
- Prefix does not overlap with another prefix on the system.

TetheringConfiguration
We're removing the dependency on TetheringConfiguration because
TetheringConfiguration is not parcelable so it cannot be used in AIDL
API. Eventually we'll make PrivateAddressCoordinator expose its
functionalities via AIDL API at RoutingCoordinator.

updateUpstreamPrefix()

UpstreamNetworkState parameter with its member class. This is because we

UpstreamNetworkState is not parcelable while its member fields are.

Since calling NetworkStatsManager.queryDetailsForUidTagState may
be blocked for up to 20 seconds, potentially leading to enable
Tethering failure, a handler thread is added to process this task
and prevent blocking.
Furthermore, thread safety is ensured for all accesses to the class
by the internal handler thread.

Instead of blocking the broadcast until onReceive returns on the

This should make no difference for the only user, the

On Android R, IpServer uses netd to set up tethering while on S+ it uses
RoutingCoordinator.
