[PATCH v0 0/2] OpenVPN logging
by Daniel Wagner
From: Daniel Wagner <daniel.wagner(a)bmw-carit.de>
Hi,
I am debugging some network setups here and found out that we don't
log anything from OpenVPN which is pretty sad. Let's fix this.
cheers,
daniel

[PATCH] dhcpv6: use correct dhcp renew time when valid life-time is infinity.
by Feng Wang
Based on RFC 3315, 22.6, the valid life-time is infinite when its
value is 0xffffffff. In the g_dhcpv6_client_get_timeouts, the expire
data type is time_t. If time_t is uint32, the last_request time plus
0xffffffff will wrapover so that expire time is smaller than current
time. Thus the dhcpv6 will restart immediately(dhcpv6_restart called).

Query about Connman Session
by Benjamin Ioller
Hello,
I'm using Connman (v-1.32) on my Raspberry Pi and I wanted to try the session mode.
I found quite few interesting mailings and I looked over the code (session.c, test-session) and the doc, but it looks like session is not really a nowadays topic.
Does someone use the Connman's session? and for which application? Can you give me an example?
So here is what I understood so far about the session mode:
Connman session allows the application to use specific network setting as selected technologies, roaming policy...
Connman uses Iptable to do so. Connman creates rules in the mangle table to mark the packet based on the UID/GID.
Then rules are added to the filter table depending on the allowed bearers, and other properties.
This routing is only functional when the connman state option is ON.
Connman proposes two ways to create a session :
First, the application creates it's own session using the method form /net.connman.manager. I try to use this method with a python script, the application creates a session, connects to it and sends UDP packet to a local host via ethernet. But I didn't manage to setup the AllowedBearers, neither with
manager.CreateSession({"AllowedBearers":Glib.Variant('s','ethernet')},notifier_path)
nor
Session.Change("AllowedBeares",Glib.Variant('s','ethernet')).
I have Variant encoding issue. Do you have any advice or exemple?
I was also wondering how does the mangle table identify the application's packet? (or maybe it's just the UID again?)
The second way is to use session_policy. With this method you can mark packet only based on the UID or GID. I need to create UID.policy in var/lib/connman/session_policy_local which contained the different parameters. But when I turn the Connman's state session On, nothing happened... My pi user is still able to use wifi even if the pi.policy have only Ethernet as AllowedBearers. I suspect the issue comes from user rights or something... Does somebody had similar issue?
By the way, is the session priority only for notification hierarchy or does the session priority have some effect on the network traffic (during congestion?)?
Hope these questions aren't too basic for you, and can help other.
If you have any literature which could help, I'll take it!
Thank you,
Benjamin

cellular reconnect
by Alexander Smirnov
Dear all,
could you also please help me with another issue, I've observed.
What I did:
- Connect cellular service in connmanctl (ppp0 appears in ifconfig)
- Disconnect physical GSM antenna (ppp0 disappears)
- Connect physical GSM antenna
After these steps I don't see cellular service (connmanctl services is
empty) till I reset the modem.
How should I handle network strength events to automatically reconnect
the cellular? Why I don't see cellular in connman services anymore?
Thank you in advance!

ConnMan and Cellular
by Alexander Smirnov
Dear all,
I'm trying to setup ConnMan to have cellular always enabled despite on
other services state.
What I did:
- Create oFono context with APN settings
- Set AutoConnect=true for cellular
- Tested manual cellular network bring up (connmanctl connect cellular...)
What I've observed:
- If ehternet cable is plugged - cellular is in idle state
- If I down ethernet - cellular becomes available
I've enabled debugging, and found that "auto_connect_service()" always
return true on the ethernet service:
src/service.c:
3772: if (service->pending ||
3773 is_connecting(service) ||
3774: is_connected(service)) {
3775: if (!active_count)
3776: return true;
Is there any way to get cellular always connected?
Thank you!

connman stops auto-connecting every day or so
by Kevin Wells
Hello,
I am running connmand 1.27 on Yocto on an edison. Every day or so, the edison stops connecting to my primary network. I can reestablish normal behavior by using “connmanctl connect wifi_…” Rebooting alone does not fix the problem.
Any help would be much appreciated.
Thank you,

[PATCH] dhcp: remove the possible remaining dhcp_retry_cb timer
by Harish Jenny K N
In the following scenario:
1. no_lease_cb() is called
dhcp->ipv4ll_client = ipv4ll_client;
err = g_dhcp_client_start(dhcp->ipv4ll_client, NULL);
ipv4ll_start(dhcp_client);
2. switch_listening_mode
--> listener_event
3. listener_event
--> ipv4ll_recv_arp_packet
---> no_lease_cb
---- > creates a new timeout (dhcp->timeout) without removing the old timeout
Logs:
src/dhcp.c:no_lease_cb() No lease available ipv4ll 0 client (nil)
src/dhcp.c:no_lease_cb() No lease available ipv4ll 1 client 0x1d1e808
src/dhcp.c:dhcp_release() dhcp 0x1d14980
There is a possibility if dhcp_retry_cb() Timeout is not called before first
no_lease_cb, then the old timer is not removed before creating the new one.
We are not sure if the dhcp object will be alive when the first timeout fires.
This could result in a potential crash.
This patch adds a defensive check to remove the potential existing timer
before creating a new one.

Search domain persistence
by Sven Schwedas
On 1.32 (possibly also older versions, haven't checked) I'm seeing an
annoying problem: Search domains persist across networks and reboots and
DHCP search domains of the currently active network are only appended.
After roaming between a few networks, this creates an absolute mess of
an /etc/resolv.conf. Is this intended behaviour? How can I disable this
if so?
