[PATCH 0/3] Improve VPN property saving and property management
by Jussi Laakkonen
These changes improve the saving of VPN properties in order to avoid
losing information if connman-vpnd crashes. Also new feature to multiple
values in one D-Bus call is added.
The first patch in this set addresses the issue of not saving VPN
provider values immediately after the value has been changed over D-Bus.
To avoid unnecessary writes to disk the value of the property is
compared to the existing one. To do this for user routes, the routes are
read into a sorted list to make the comparing of them more efficient. As
a result each successful value change will be written immediately to
provider settings.
The second patch adds a new feature to add multiple VPN provider
properties using one D-Bus call: SetProperties. This new function
accepts input in the same format as GetProperties returns. This changed
improves the performance when changing multiple values as the saving of
properties is done after the complete dict is processed, if there are
any changes to any of the values. Empty values are also allowed to be
able to set and clear certain values in one D-Bus method call. In case
there are errorous properties these are reported back as comma separated
property name list at the end of the appropriate error message.
The third patch adds documentation of the SetProperties D-Bus method and
also documents all errors for SetProperty and ClearProperty D-Bus
methods.

This sounds like as if the agent code in ConnMan caches some state and
doesn't update it correctly. The state should be tracked by services,
so it's kind of unclear to me how the second service is able to
interfere with the first one. I suggest to enable the log for the
agent code and try to figure out what is going on, e.g. connmand -n -d
src/agent.c. Maybe you need to enable the logs (connmand -n -d) but
that might be too much info. Also if you don't see any interesting,
add more DBG() statements to see what the state machine is doing.
Thanks,
Daniel

I think I cracked the problem. ipconfig.c stores the values in struct
ipconfig, which is the current applied configuration. Whenever we
disconnect a service service.c will call
__connman_ipconfig_address_remove(). This clears struct ipconfig and
after that we try to save it.
The values of ipconfig_ipv4 in struct service needs to be saved if the
method is manual and not dhcp.

Uh, that's the only thing in the settings file left?

Alright, so that explains something. The other settings were also lost
but we only the gateway differently. In fact all the manual config
get's lost.

IIRC, the steps are
1) service configure manual
2) disconnect service
3) reconnect service
?

Connection to WPA fails following connect-failed error
by Karine Ouellet
Can you help with the following issue? We are experiencing problem when connecting to a WPA service following a connect-failed error on another service.
We are using connman 1.37 with wpa_supplicant V2.9Initial state:
$ connmanctl> connect <first_service>
Passphrase = [ Type=wep, Requirement=mandatory ] Passphrase? <Enter RIGHT passphrase>
Connected <first_service>
To reproduce the issue:
1. Connect to another WPA service by issuing wrong passphrase. The connection is unsuccessful as the wrong key is entered (expected behaviour).
$ connmanctl> connect <second_service>
Passphrase = [ Type=wep, Requirement=mandatory ] Passphrase? <Enter WRONG passphrase>
Agent ReportError <second_service>
connect-failed
Error /net/connman/service/<second_service>: Input/output error
Agent request cancelled by ConnMan
2. Connect again to the same service, the agent doesn't ask for passphrase.
3. Remove the stored passphrase
connmanctl> config <second_service> --remove
*
4. Try to connect to the first service (used in the initial state above). We should be able to connect to the service without user input. However, we systematically receive the following error at the first attempt.
connmanctl> connect <first_service>
Agent ReportError <first_service>
connect-failed
Error /net/connman/service/<first_service>: Input/output error
Agent request cancelled by ConnMan
5. Redo the previous operation. This time, the connection is done properly.
$ connmanctl> connect <first_service>
Connected <first_service>
Any advice or guidance would be greatly appreciated!

[HELP :-) ] 3g modem auto connect
by nick83ola
Dear Connman developers,
I have a telit HE910-D modem that I need to make it work inside yocto.
the modem is correctly recognized both by connman and ofono
connmanctl services
*AO Wired ethernet_0001c021c253_cable
3 cellular_272023119202599_context1
...
And it work fine if I issue the command
connmanctl connect cellular_272023119202599_context1
And it also reconnect after reboot
My issue is that the first time that you connect the modem
(if there's no configuration folder for it in /var/lib/connman) it doesn't
connect automatically
I need a way to say to connman that if there's any cellular modem connected
just connect to it.
there's an option or something that I can do without monitoring connman
through dbus?
Is this the correct connman behaviour?
Kind Regards
Nicola Lunghi

How to set up cellular.config with AccessPointName?
by JH
Hi,
Hi,
I cannot find any document for cellular.config syntax, can I I set up
AccessPointName in cellular.config?
I tried following file, it did not work, I know if I have a correct
Name = <SIM service provider>, it will work, but i don't know the name
of the service provider, I only knows the AccessPointName for Aeris
which I think that APN is a gateway to connect to its network.
$ vi /var/lib/connman/cellular.config
[global]
Name = cellular
Description = Cellular
[service_cellular]
Type = cellular
AccessPointName = iot-eu.aer.net
Appreciate your advice.
Thank you.
Kind regards,

Why can't connman automatically enable and connect to cellular network interface?
by JH
Hi,
I installed oFono plugin to an embedded system where the cellular is
used, I suppose that the connman should automatically enable and
connect to cellular when it first time boot up, it didn't, I have to
manually run the connmanctl command to enable and to connect it. In a
product due to limited Flash storage size, I'll not install connmanctl
and there will be no manual interactive process, how can I set up
connman to automatically enable and connect to cellular network
interface?
Thank you.
Kind regards,
