As we want to track system-only network traffic, the traffic through wifi-hotspot and usb tethering are two of important information. This bug is intended to find a way to catch these traffic.
Support the command to retrieve tethering traffic in netd through NetworkManager.js. The command is bandwidth gettetherstats ifname1 ifname2 The result returned by netd is ifname1(receive) ifname2(transmit) rxbytes rxpackets txbytes txpackets so we are going to hold the values of rxbytes and txbytes here.

The most important issue here is that we need to collect the data before tethering is closed/disabled, otherwise we'll lose these data.

Summary: Need a way to track network traffic through Wifi-Hotspot and USB tethering → [Network Metering] Obtain network tethering statistics (e.g., WiFi tethering, USB tethering)
In this patch, there are several modifications include: 1. make sure tethering stats is retrieved before tethering is disabled/changed (e.g., switch connection type between wifi and 3g) 2. then the stats will be saved in a cached by Tethering Type (USB, WiFi) 3. NetworkManager will send out notification to tell that there is cached stats available. 4. use last stats to handle the case if tethering stats are retrieved when tethering is enabled. (since we always get the accumulated stats from netd) ex. first time get: newStats = stats; lastStats = stats; second time: newStats = stats - lastStats; lastStats = stats; ...etc.

Base on the separated purposes of NetworkManager and NetworService, the work of obtaining tethering stats will modified. In short, NetworkService will firstly get tethering interface pair from NetworkManger and then use the pair to query tethering stats through NetworkService.

Tethering statistics can be obtained by a similar way as how we get interface statistics. That is, get statistics through netd. However, there also several problems we need to deal with: 1. It requires tethering interface pair (internal interface and external interface) to query statistics from netd. 2. If tethering is disabled or under internal interface change (only for USB tethering, internal interface can be switched between WiFi and 3G), the previous statistics will lose. To solve problem 1., the getTetheringStats interface is exposed by NetworkManager, which is in charge of network information. Thus, networkStatsService can simply query tethering statistics by type (WiFi or USB) without knowing interface pair. For problem 2., cases including tethering disable and interface change are forced to obtain tethering statistics and save them through networkStatsServiceProxy before taking action. If tethering statistics is queried actively by networkStatsService, it use the original way as how we deal with obtaining interface statistics.

(In reply to John Shih from comment #15) > Created attachment 8357698 [details] [diff] [review] > Bug 928289 - Part 2: NetworkStatsService.jsm modification. r=gene, albert I did a quick review to see your design and I have two points that I would discuss with you: 1) You add a new '_tethering' array to save tethering types, which is very similar to '_networks' array. That makes you to duplicate some code to process both arrays ( in 'updateAllStats', 'updateStats', 'updateQueueIndex' and 'update'). As tethering can be conceptualized as a network I think you can add it to the '_networks' array, so you won't need to duplicate code, just check network type when updating in order to know if you have to call 'getTetheringStats' or 'getNetworkStats'. Does it make sense to you? 2) In first versions of NetworkStats API I placed the 'getNetworkStats' netd connector in the NetworkManager like you did with 'getTetheringStats', but then someone move it to the NetworkService. Do you know where it should be placed? (is just to understand why one function goes in NetworkService and why the other goes to NetworkManager).

Does it make sense to you? Yes, I've also considered about it. Then I decided to have separate arrays in order to reduce the impact on original logic. But with your suggestion, I will integrate them. > > 2) In first versions of NetworkStats API I placed the 'getNetworkStats' netd > connector in the NetworkManager like you did with 'getTetheringStats', but > then someone move it to the NetworkService. Do you know where it should be > placed? (is just to understand why one function goes in NetworkService and > why the other goes to NetworkManager). This is actually an issue I've met. The work of splitting NetworkManager into NetworkManager and NetworkService is aiming at making NetworkManager purely take charge of network information. The code related to sending commands to net_worker is moved to NetworkService, so some works can be done without going through NetworkManager. Under this architecture, there is no specific impact for getNetworkStats because it only require interface name, which can be easily obtained and maintained without the help of 'new' NetworkManager. However, it is little complicated for getTetheringStats due to two main problems: 1. It requires interface pair (internal interface and external interface) when querying tethering stats. 2. It is unable to map tethering interface pair to nsINetworkInterface (which is needed to query icc Id). Both tethering interface pairs and nsINetworkInterface are hold in NetworkManager. As a result, it would require lots of communication (among NetworkStatsService, NetworkManager, NetworkService) and additional interfaces (such as obtain tethering pair, query nsINetworkInterface) if placing getTetheringStats in NetworkService. After having some discussion with RIL guys, we finally decide to use this design to make the work more simple. (but it still needs their review) IMO, getNetworkStats is at the right place (NetworkManager) based on the responsibility of current NetworkManager and NetworkService, while there are some compromises to have getTetheringStats placed in NetworkManager.

Patch updated. The original object _networks is changed to _connections, which integrates both available networks and tethering.

Initially, the goal to do so is to make sure self._db.find is called after updating each network (interface/tethering) in getSamples Thanks

Yes, I get tethering stats before it is truly disabled. But it's a internal work in NetworkManager.

Sorry, > I guess I miss something.. You are right. There are two cases for updating tethering stats: 1. NetworkStatsService actively queries when getSample() or updateAllStats() is called 2. NetworkStatsService passively updates when tethering is disabled or connection changed (these two situations would cause data lose so that we need to get data in advance) Note that case 2. is an internal work in NetworkManager.

Hi Gene, Albert, Since the way to get tethering stats is so mush similar to interface stats, it makes me to think how to integrate them. After some consideration, I decide to move the logic of handling accumulative stats (such as the use of rxSystemBytes/txSystemBytes) from NetworkStatsDB.jsm to NetworkStatsService.jsm. In short, with this work, all network stats (per-app/per-service/per-interface) will all firstly be cached in NetworkStatsService.jsm and then get update when getSample() or updateAllStats() is called. I think this design can make our current architecture more clear and also solve some problems. Indeed, it needs your feedback first, thanks!

I've been doing some testing and reported stats are greater than the real ones. In order to detect it, launch usage application and compare results with the report of the system: adb shell cat /proc/net/dev It seems that stats from the API are the double of the real stats. BTW, Part 1 and Part 2 need a small rebase.

Thanks for pointing this out! After some investigation, it is caused by continuously receives NetworkStats:Get in very short time. Cached can not be cleared before the next getSample() is executed.

Maybe is better to enqueue the cached array operations, as it is the resource that need a lock. BTW, I would appreciate if you use more functions, some ones are big and makes harder to understand the code. :)
