2020-06-17Fix the potential NPE when calling IPMS API and ExecutionException is thrown.Xiao Ma
Listener callback argument is marked as @Nullable in some APIs, means client isn't interested in learning about return value, in these cases should check if it's null or not before using this callback.

2020-06-11Remove DhcpResults from NetworkStack shared libRemi NGUYEN VAN
Remove the dependency on DhcpResults in moduleutils by moving toStableParcelable to NetworkStack main code, and fromStableParcelable to the test only. Only NetworkStack should be generating DhcpResultsParcelables, and only the NetworkStack should be using DhcpResults at this point (eventually the class would move from frameworks/base/core to NetworkStack).

2020-04-28Address comments on NetworkStack AIDL v6Remi NGUYEN VAN
Address issues found during AIDL review: - Rename clientAddr to singleClientAddr - Do not use a ParcelableBundle for notifyNetworkTested or notifyDataStallSuspected; instead use AIDL parcelables for stronger backwards compatibility guarantees. As part of moving notifyNetworkTested to using a parcelable the test result int is split into two: the actual evaluation result, and the probesSucceeded int. It used to contain both as a bit mask, which does not make sense if probesAttempted is in a separate int itself.

2020-04-20Get the l2key and grouphint from the initial provisioning configuration.Xiao Ma
The purpose of processing CMD_UPDATE_L2INFO command in the Stopped State is just to update the initial l2key and grouphint which are used when starting DhcpClient (e.g. for INIT-REBOOT). We can get both of l2key and groupHint from the initial prov configuration parcelable instead, then be able to delete CMD_UPDATE_L2INFO from the StoppedState.

If specific config "clientAddr" is set, the DHCP server will only offer "clientAddr". This is for peer-to-peer use case. If there are multiple clients for which "clientAddr" is already in use, dhcp server will not offer other addresses to clients.

This change adds a new filed: bssid in the ScanResultInfo class which are encapsulated by WiFi when connecting to AP successfully, using current connected AP's bssid as a hint to determine whether L2 roaming happened or not.

2020-02-20Add ModuleNetworkStackClientRemi NGUYEN VAN
NetworkStackClientBase / ModuleNetworkStackClient extract functionality from NetworkStackClient in services.jar, only keeping what is needed for modules to communicate with the NetworkStack, and not the framework code that starts the NetworkStack (and uses hidden APIs). As the NetworkStack is started asynchronously, it is possible for it not to be registered yet right after boot, so some polling is implemented to queue requests until it is ready. NetworkStackClient will inherit from NetworkStackClientBase so that components in services.jar can access the NetworkStack, using the same asynchronous mechanism as before (execute pending requests once the service is connected).

2020-02-14Add shims for network info classesRemi NGUYEN VAN
Combine shims for LinkProperties and NetworkCapabilities to avoid too many shim classes, and use static methods as the original types (and not the shims) would generally be used to reference the classes. CaptivePortalData is not available in API29 so CaptivePortalDataShim is used as a wrapper that can hold a reference to it in common code. Sample usage in NetworkMonitor: final CaptivePortalDataShim data; try { data = CaptivePortalDataShimImpl.fromJSON(obj); } catch (UnsupportedApiLevelException | JSONException e) { // Do some fallback return; } // Just to give an idea if (data.isCaptive()) { openCaptivePortalApp(data.getUserPortalUrl()); } data.notifyChanged(mCallbacks); Test: atest NetworkStackTests NetworkStackNextTests Bug: 139269711 Change-Id: I262aaa41013ebe1ec4263a6516bd8cab76509304

2020-02-10Add ScanResultInfo object in ProvisioningConfiguration parcel.Xiao Ma
Since wifi.ScanResult doesn't implement specific equals() yet, for comparing the ProvisioningConfiguration object better, this change encapuslates ScanResult#SSID and ScanResult#InformationElement member into a new class: ScanResultInfo inside ProvisioningConfiguration. Adding ScanResultInfo object in ProvisioningConfiguration parcelable is to check the InformationElement filed when starting IpClient and detect whether or not the specific OUI is included in the IEs.

2020-02-05Define callback for suspected data stall.Cody Kesting
Currently, NetworkStack does not notify ConnectivityService explicitly when it detects a potential data stall.

2019-09-05Move NetworkStackClient lib to NetworkStack folderRemi NGUYEN VAN
The AIDLs and ipmemorystore-client were already statically linked libraries, so their location in the source tree does not change anything (they were already built into the NetworkStack module and the framework). It makes more sense to have them in the NetworkStack module folder however, as changes to these files will be released with the same cadence as the module, not the framework.
