If the PAN service disconnects before the BT iface is available, the BT
TetheringRequest will be stuck pending and prevent any new BT
startTethering attempts. This may happen if the user turns BT tethering
on and turns off BT without connecting to any device.
Fix this by always removing the pending BT request when the PAN service
disconnects.
Flag: EXEMPT minor bugfix
Bug: 420412916
Test: atest TetheringTest, manually verify turning BT tethering on,
turning off BT, and turning BT tethering on again.

Remove ensureIpServerStartedLegacy.
Never create IpServers based on interface up for WIFI and WIFI_P2P.
Rename the methods in the legacy codepath for clarity.
Patrick Rohrauthored and Android (Google) Code Reviewcommited 2025-05-16 02:15:46 -07:00
This is not necessary because creating the IpServer based on
interface events is only necessary for the tether() API, and
field metrics indicate that that API is unused for WIFI and
WIFI_P2P.
Also add comments to clarify when the legacy codepath is taken.

AOSP code has never used this API, and metrics from production
show no usage either. Removing it will allow simplifying the
code.
This CL removes testRequestStaticIpLegacyTether because it makes
legacyTether a no-op and there is already a test for static IP
request right above it.

Currently, Tethering feature flags are located in
TetheringConfiguration or other classes. However,
not all flags are truly related to the tethering configuration.
Therefore, create the TetheringFeatureFlags class to centralize
and manage these feature flags more easily.

TetheringTest has several tests that rely on starting Wifi tethering,
but do not mock WifiManager.startTetheredHotspot. This causes the
pending Wifi request to be removed, even though the test continues
thinking that the call succeeded and continues mocking Wifi AP events.
Fix this by making sure the mock returns true in setUp(), and only set
it to false when we expect that the call should fail.

stopTethering with a TetheringRequest should only stop tethering if
there is an existing request (pending or serving) that fuzzy-matches the
input and whose UID matches the caller (unless the caller is Settings,
which is allowed to remove any request).
If there is no existing fuzzy-matched request, return
TETHER_ERROR_UNKNOWN_REQUEST.
Note: This was originally merged as aosp/3527440 but was reverted due to
a dependency CL being reverted. Remerging this on top of the fix for the

Legacy behavior will return success results to multiple startTethering
calls of the same type, even though the link layer can only support one
of those requests at a time (other than tethered AP + LOHS).
For B+, clean up this behavior by only allowing the amount of requests
that the link layer can concurrently support. To do this, we'll
introduce the concept of "fuzzy-matching" such that if a new request
fuzzy-matches an existing request (either pending or serving), this
indicates that the link layer cannot support the new request
concurrently, and we'll fail the new request with
TETHER_ERROR_DUPLICATE_REQUEST.
To keep track of serving requests, we'll store the request and it's
IpServer in RequestTracker when we call IpServer.enable(), and we'll
remove it (indexed by IpServer) when
1) Calling IpServer.onStop()
2) Calling IpServer.unwanted()
3) We detect an IpServer transition to AvailableState with error code
Note: This was originally merged as aosp/3529632 but was reverted due to
a crash when reading aconfig flags at boot. That issue has been fixed
here.

failureEnablingIpForwarding verifies that TetheringMetrics sends one
more error report than it should. This extra verification is caused by
any(class) being passed into the mock WifiManager.startTetheredHotspot,
which does not match null even though the actual code passes in a
null. This results in an extra failure that causes the extra error
report call.
Fix this by replacing any(class) with null, and removing the extra error
verification.

Currently there may be multiple identical bluetooth requests waiting for
the PAN service to connect before their listeners are notified. To
simplify future code, we should only allow one pending request/listener
pair at a time, and reject every subsequent request with
TETHER_ERROR_SERVICE_UNAVAILABLE.
This should be OK because
1) Bluetooth tethering is hardly used at all
2) Settings disallows extra startTethering calls between the first call
and the bluetooth service starting
3) Apps are expected to handle TETHER_ERROR_SERVICE_UNAVAILABLE
correctly.

Mockito extended tends to cause all kinds of issues due to the way it
injects itself into the bytecode of framework classes instead of
creating subclasses.
Use non-extended mockito as it is not actually necessary for current
tests.
