[RFC] Wi-Fi Protected Setup (WPS) connection
by Jose Blanquicet
Hello everybody,
We would like to propose a RFC to change the way to manage the WPS
connections. Following we present our proposal and the reasons for
suggesting it:
Current implementation of WPS connection requires to specify the service to
which the user wants to connect, and when the connection is going to
finalize, a verification is done in *handle_wps_completion* function to
ensure that the SSID of the AP actually being connected was the one
specified by the user. This violates the WiFi Alliance specification over
WPS and the WPS Certification plan because:
1. WiFi Alliance admits to certify devices that have no mean for the
user to choose an AP to connect to, they define them as "Client devices
with only a simple display or a fixed label containing a setup password"
(Pag. 12 of Wi-Fi Simple Configuration Technical Specification Version
2.0.5)
1. The WPS protocol includes the transition from un-configured to
configured state of the AP when the first Enrollee connects, some Access
Points change their SSID during this transition, that would cause the
ConnMan to invalidate the connection. A tipical example of such Access
Point is the Atheros used in test 5.4.2 of Wi-Fi CERTIFIED™ Wi-Fi Protected
Setup™ Interoperability Test Plan – Version 2.0.15
After having performed a detailed study of the wpa_supplicant
implementation for the WPS, we propose to implement a solution with the
following general characteristics:
1. The new implementation must keep current WPS implementation for
compatibility support, but as deprecated.
2. In order to meet the specifications of Wi-Fi Alliance and based on
what the WPS D-Bus Interface of wpa_supplicant offers (Documented in
https://w1.fi/wpa_supplicant/devel/dbus.html#dbus_wps) we propose to add
two methods to the Technology D-Bus Interface: *StartWPS* and *CancelWPS*,
analogous to functions WPS.Start and WPS.Cancel provided by
wpa_supplicant. In this way there is no service specified enabling simple
devices to offer a very basic interface to the user for starting the WPS
session. Both methods would be supported only by WiFi technology.
3. On the other hand, some advanced WiFi modules expose more than one
network interface (one for P2P, one for STA, one for AP ..) that can be
active at the same time, and it is then desirable to not let connman
randomly choose on which start WPS, thus we propose also to add the
possibility to specify the interface over which either the start or cancel
action will be performed. This would not be a mandatory parameter in order
to keep the things easy for more simple systems.
Please find below the implementation proposal:
*StartWPS:*
Following the approach of wpa_supplicant, we propose to add the possibility
to choose which role to assume (enrollee, registrar), which authentication
type use (pin, pbc) and get back the pin to be used (if required), as well
as wpa_supplicant does. At this point, we can briefly define a possible
prototype of the method:
dict StartWPS(dict parameters)
Where the returned dictionary could be empty or composed by at most one
entry, which will be the just generated PIN by the wpa_supplicant, in case
it was requested. On the other hand, the function would receive a
dictionary with possible keys: “Ifname", "Role", "Type" and "Pin"; where
“Ifame” is an optional parameters covering previous defined characteristic
for complex systems. Whereas, parameters "Role", "Type" and "Pin" follow
exactly the same behavior of the table presented in
https://w1.fi/wpa_supplicant/devel/dbus.html#dbus_wps for method Start
of fi.w1.wpa_supplicant1.Interface.WPS
Interface.
When the *StartWPS* method gets called, it should verify if interface was
specified through “Ifname” entry key. If so, WPS Session will be started in
that specific interface, otherwise we suggest to look for the first
available interface with the capabilities to start a WPS Session among the
device_list of the Wi-Fi Technology. If it is found, then use it, if not
return "[service].Error.NotSupported”.
Additionally, current implementation does not allow to start a WPS Session
when the device is playing as Access Point (Tethering). On the contrary,
wpa_supplicant does. Therefore, we propose to also add this possibility to
the new implementation. It would be possible if a Service D-Bus Object is
not required for starting a WPS Session, which would be true if the new
methods are added to the Technology D-Bus Interface, as we propose.
*CancelWPS:*
This function does not require for any particular parameter. So, we propose
to only continue giving the option to specify the interface. Therefore, the
possible prototype of the method would be:
void CancelWPS(dict parameters)
Where the received dictionary could be empty or composed by at most one
single entry if the user wants to specify the interface using the key
“Ifname”. If so, the *CancelWPS* function should cancel the ongoing WPS
Session running in that specific interface. Otherwise, we suggest to do it
over all the Device of the Wi-Fi Technology (device_list).
*Going into details of implementation*:
After having studied the ConnMan architecture we think to associate the WPS
concept to the Device Infrastructure because if we want to add the
possibility of specify the interface (“Ifname”), the Device is the
corresponding represents of a real device inside the ConnMan. Therefore, we
think it is the best choice. Additionally, *StartWPS* and *CancelWPS*
should be added to the device driver:
*static* *struct* connman_device_driver wifi_ng_driver = {
.name = "*wifi*",
.type = *CONNMAN_DEVICE_TYPE_WIFI*,
...
.start_wps = wifi_start_wps,
.cancel_wps = wifi_cancel_wps,
};
It means that WiFi plugging must implements both methods wifi_start_wps and
wifi_cancel_wps. In particular, wifi_start_wps will need to receive the WPS
parameters to then pass them to the ConnMan’s supplicant handler
(gsuppicant/supplicant.c), which is the only one that interacts directly
with the wpa_supplicant.
Next, the supplicant handler will call methods Start or Cancel of the
fi.w1.wpa_supplicant1.Interface.WPS
D-Bus Interface of the wpa_supplicant, with the required parameters. In
case the method Start returns the newly generated PIN it has to be
forwarded towards the Technology to then be added as an entry in the
directory that would be returned by the *StartWPS* method. It would imply
that we have to store the request message of the *StartWPS* method in order
to reply possibly with a the PIN generated by the wpa_supplicant. To do it,
we propose to store that message in the Device structure in order to be
coherent with the association we previously proposed between the WPS and
Device.
Once the WPS Session has been initiated, it could finalize successfully or
fail. The current implementation does not provide further information about
such a events. Given that, we propose to notify the following events (Just
the most commons):
- Success: WPS provisioning has finished successfully.
- Password Authentication Fail: When pin entered in the registrar was
wrong.
- PBC-Overlap: When an enrollee detects two registrars with PBC session
active.
We think to perform those notifications using a D-Bus Signal added to the
Technology Interface, let’s call it *WPSEvent*. It would simply indicate
when one of the described event takes place. We propose to just provide a
string with the name of the event: "success", "pwd-auth-fail" or
"pbc-overlap", following the wpa_supplicant notation. All this information
is already provided by the wpa_supplicant in the event
fi.w1.wpa_supplicant1.Interface.WPS.Event, thus it just need to be
forwarded to the Technology in order to be emitted.
In order to forward WPS events, we propose to follow the implementation of
the communication between the plug-in and the supplicant handler, it means
to use the callback mechanism adding a new callback:
*static* *const* GSupplicantCallbacks callbacks = {
...
.wps_event = wps_event,
};
Thus the wifi plug-in must implement the wps_event function that will
basically just call a Technology function that will emit the proposed
signal.
What do you think about our proposal? Of course, everybody is welcome to
give feedbacks and suggestions.
Best regards,
Jose Blanquicet

[PATCH] plugins/wifi: Do not disable network on Disconnect
by naveen＠nestlabs.com
From: Naveen Singh <nasingh(a)google.com>
Connman currently disables network on a disconnect event. This severely
impacts wpa supplicant ability to roam to same or different BSSID. The
act of disabling network disables the complete network profile in wpa
supplicant and it does not try to connect on its own and then waits for
a new connection attempt from connman. This delays the re-connection
timings. Once a network is disabled, wpa supplicant will generate a
locally generated deauth while a connection is going through.
wpa_supplicant is currently has the best knowledge of getting back L2 level
connectivity.With this change this is how it would appear in log lines
when a deauth with reason code 7/6/4 is received:
1. wpa_supplicant gets the reason code 7 deauth
2. wpa_supplicant starts a fast connect attempt
3. wpa_supplicant generates a disconnect notification to connman
4. connman calls set_disconnected which would make device lose its
current IP address.
5. service is disconnected as well.
6. wpa_supplicant gets device connected back to same AP in this case
7. wpa_supplicant generates connected event.
8. connman starts with DHCP request (having same IP as the previous
one).

[PATCH] Supporting wifi load balancing and band steering
by naveen＠nestlabs.com
From: Naveen Singh <nasingh(a)google.com>
Enterprise APS sometimes refuse association with assoc response
status code 17. AP basically wants to steer client to a right
band or a better AP for load balancing purposes. This does not
use to work as connman has no way to know that association was
denied and it would treat this disconnect notification as a normal
disconnect. wpa supplicant was sending DisconnectReason on DBUS as
a part of PropertyChanged signal but there was no AssocStatusCode.
In this commit id of hostapd (c7fb678f3109e62af1ef39be9b12bf8370c35bde)
wpa supplicant is also sending assoc status code as a part of
PropertyChanged DBUS signal. Idea is that on a disconnect notification
from wpa supplicant, if the prior interface state is associating
(means a conection is underway) and association was denied with status
code 17 then do not proceed. This would let wpa_supplicant chose another
BSSID where association would stick.
This is been tested by running a stress test which tries connection with
an enterprise AP which frequently denies association with status code 17.

[PATCH v3] gsupplicant: Optimize AddNetwork Handler by avoiding DBUS call.
by naveen＠nestlabs.com
From: Naveen Singh <nasingh(a)google.com>
In case network path is not NULL, network should only be removed
if the new network (to be added) is different from what is sitting
in wpa_supplicant. This would avoid two DBUS calls: AddNetwork and
SelectNetwork.

Manual DNS configuration with DHCP services
by Moberg, Patrik
Hello,
What is the best practise when using Connman to achieve manual configuration of DNS when using DHCP based services? The goal is to regardless of which service that is online always use a manual DNS.
With auto connect disabled, I have tried to set "Nameservers.Configuration" (via d-bus) to an IP address prior to the service being connected (connect done via d-bus as well). The service then looks ok with the proper IP address in "Nameservers" for the service. However the routing table is then unexpectedly populated. For example, the default gateway entry has destination set to IP in "Nameservers.Configuration", with gateway set to DHCP DNS IP address, and netmask 255.255.255.255.
Cheers,
Patrik Moberg

RFC: multipath routing for services and sessions
by Dragos Tatulea
Hello,
We've been working recently on adding a few features to ConnMan for
Multipath TCP. However, most features are not related to Multipath TCP
and they could be useful in upstream. Please let me know what is of
interest from the list below:
* Per service multipath routing: This is a per service flag that
allows the installation of a multipath table for a service.
Something in the lines of:
$> ip rule
0: from all lookup local
32763: from 10.10.3.2 lookup 283
32764: from 10.10.2.2 lookup 281
32765: from 10.10.1.2 lookup 279
32766: from all lookup main
32767: from all lookup default
$> ip route show table 283
default via 10.10.3.1 dev vethc3
10.10.3.0/24 dev vethc3 scope link
There are 3 services above with multipath routing on.
There's also a generic switch to turn it on by default in all
services.
* Multipath routing support for sessions: Each session contains a list
of services that are added automatically if they have the multipath
option set and they are considered connected. For all those services,
fwmark + src ip rules are created to the service multipath routing
table. It would look like this:
$ ip rule
0: from all lookup local
32760: from 10.10.1.2 fwmark 0x10000 lookup 261
32761: from 10.10.3.2 fwmark 0x10000 lookup 265
32762: from all fwmark 0x10000 lookup 65536
32763: from 10.10.3.2 lookup 265
32764: from 10.10.2.2 lookup 263
32765: from 10.10.1.2 lookup 261
32766: from all lookup main
32767: from all lookup default
The default service is not added to this list. But it has the
default rule (32762).
It's also possible to modify the list via the DBus API.
* Flow Selectors: this is a fancy name for per session 5 tuple
iptables rules. A 5 tuple contains: source/destination ip,
protocol (tcp|udp), source/destination port. Fields can also be
omitted. 3 rules would look like this:
$ iptables -t mangle -L
...
Chain connman-OUTPUT (1 references)
target prot opt source destination
MARK tcp -- 11.11.11.11 22.22.22.22 tcp spt:1111 dpt:2222 MARK set 0x10000
MARK all -- 33.33.33.33 44.44.44.44 MARK set 0x10000
MARK udp -- anywhere anywhere udp spt:7777 dpt:8888 MARK set 0x10000
...
Currently these tules are only added to the output chain. But that can
be made more flexible.
These work as/in tandem with policy descriptors. The idea is to bind
a certain kind of traffic to a session. However, you don't necessarily
need a policy file for them. They can be set via the session API too.
Would these features be interesting for upstream ConnMan? If yes, I'd
gladly split the current patches [1] into per feature patch sets and
send them here. Please let me know.
