New Note 58 Given i.MX6 hardware with ARMv7 processor, I'm having intermittent failures when connecting to access points. It's intermittent in that I can sometimes connect to an access point then other times, connecting fails. From what I can see, we authenticate properly, but then fail to get a password via dhcp. I'm running connman 1.25 and I'm connecting by using the DBUS interface. This is built with Yocto. Is there any other information you need? Has this been fixed in a later release? Is there a bugzilla I can go to in order to search for similar problems? Here's the debug output from a failure. connmand[510]: Skipping disconnect of 43533635782d3136302d4368757061636162726173_managed_none, network is connecting. connmand[510]: wlan0 {add} route ff00:: gw :: scope 0 <UNIVERSE> connmand[510]: wlan0 {add} route fe80:: gw :: scope 0 <UNIVERSE> connmand[510]: wlan0 {RX} 32 packets 4991 bytes connmand[510]: wlan0 {TX} 299 packets 53708 bytes connmand[510]: wlan0 {update} flags 69699 <UP,RUNNING,LOWER_UP> connmand[510]: wlan0 {newlink} index 3 address E0:E5:CF:7C:60:FC mtu 1500 connmand[510]: wlan0 {newlink} index 3 operstate 6 <UP> connmand[510]: wlan0 {RX} 32 packets 4991 bytes connmand[510]: wlan0 {TX} 299 packets 53708 bytes connmand[510]: wlan0 {update} flags 69635 <UP,LOWER_UP> connmand[510]: wlan0 {newlink} index 3 address E0:E5:CF:7C:60:FC mtu 1500 connmand[510]: wlan0 {newlink} index 3 operstate 5 <DORMANT> connmand[510]: wlan0 {RX} 32 packets 4991 bytes connmand[510]: wlan0 {TX} 299 packets 53708 bytes connmand[510]: wlan0 {update} flags 69699 <UP,RUNNING,LOWER_UP> connmand[510]: wlan0 {newlink} index 3 address E0:E5:CF:7C:60:FC mtu 1500 connmand[510]: wlan0 {newlink} index 3 operstate 6 <UP> connmand[510]: wlan0 {add} address 192.168.8.27/32 label wlan0 family 2 connmand[510]: wlan0 {add} route 0.0.0.0 gw 0.0.0.0 scope 253 <LINK> connmand[510]: wlan0 {RX} 33 packets 5333 bytes connmand[510]: wlan0 {TX} 306 packets 55004 bytes connmand[510]: wlan0 {update} flags 4099 <UP> connmand[510]: wlan0 {newlink} index 3 address E0:E5:CF:7C:60:FC mtu 1500 connmand[510]: wlan0 {newlink} index 3 operstate 2 <DOWN> connmand[510]: wlan0 {del} route fe80:: gw :: scope 0 <UNIVERSE> connmand[510]: wlan0 {del} route ff00:: gw :: scope 0 <UNIVERSE> connmand[510]: Probably roaming right now!

Connman Error wifi: Operation not permitted [HELP please]

by Jared Harvey

Hello, I'm having problems getting connman to turn on my wifi. It appears I have a permission problem. Can someone please suggest some next steps for getting the WiFi routing traffic to the internet? It appears I have a functional kernel driver, but for some reason I can not get connman to turn the wifi module on. It fails to scan networks. Here is a bunch of information from my particular setup.

[PATCH] bluetooth: Check for network in callbacks

by Patrik Flykt

If there is an ongoing connect or disconnect when the system is suspended, the Bluetooth PAN device might be gone when the system resumes. This can cause the network being removed before the connect or disconnect callback is called. As the connect or disconnect callback do not re-check for an existing pan->network, a crash will happen as a NULL network is accessed. Fix this by verifying that pan->network exists when the callback is called. connmand[9153]: src/network.c:__connman_network_disconnect() network 0x563544e6ca30 connmand[9153]: plugins/bluetooth.c:bluetooth_pan_disconnect() network 0x563544e6ca30 connmand[9153]: src/network.c:connman_network_unref_debug() 0x563544e6ca30 name phone ref 3 by src/service.c:4687:service_free() connmand[9153]: src/ipconfig.c:__connman_ipconfig_unref_debug() 0x563544e58330 ref 0 by src/service.c:4697:service_free() connmand[9153]: src/ipconfig.c:__connman_ipconfig_disable() ipconfig 0x563544e58330 connmand[9153]: src/ipconfig.c:__connman_ipconfig_unref_debug() 0x563544e81fd0 ref 0 by src/service.c:4704:service_free() connmand[9153]: src/ipconfig.c:__connman_ipconfig_disable() ipconfig 0x563544e81fd0 connmand[9153]: plugins/bluetooth.c:bluetooth_pan_remove() network 0x563544e6ca30 pan 0x563544e580b0 connmand[9153]: plugins/bluetooth.c:pan_remove_nap() network 0x563544e6ca30 pan 0x563544e580b0 connmand[9153]: src/device.c:connman_device_remove_network() device 0x563544e630d0 network 0x563544e6ca30 connmand[9153]: src/device.c:free_network() network 0x563544e6ca30 connmand[9153]: src/network.c:network_remove() network 0x563544e6ca30 name phone connmand[9153]: plugins/bluetooth.c:bluetooth_pan_remove() network 0x563544e6ca30 pan (nil) connmand[9153]: src/network.c:connman_network_unref_debug() 0x563544e6ca30 name phone ref 2 by src/device.c:378:free_network() connmand[9153]: src/network.c:connman_network_unref_debug() 0x563544e6ca30 name phone ref 1 by plugins/bluetooth.c:160:pan_remove_nap() connmand[9153]: src/network.c:connman_network_unref_debug() 0x563544e6ca30 name phone ref 0 by src/device.c:378:free_network() connmand[9153]: src/network.c:network_destruct() network 0x563544e6ca30 name phone connmand[9153]: plugins/bluetooth.c:pan_connect_cb() network (nil) org.bluez.Error.Failed connmand[9153]: src/network.c:connman_network_set_associating() network (nil) associating 0 connmand[9153]: Aborting (signal 11) [src/connmand] connmand[9153]: ++++++++ backtrace ++++++++ --- plugins/bluetooth.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/plugins/bluetooth.c b/plugins/bluetooth.c index 401bb30f..f759a902 100644 --- a/plugins/bluetooth.c +++ b/plugins/bluetooth.c @@ -206,7 +206,7 @@ static void pan_connect_cb(DBusMessage *message, void *user_data) DBusMessageIter iter; pan = g_hash_table_lookup(networks, path); - if (!pan) { + if (!pan || !pan->network) { DBG("network already removed"); return; } @@ -273,7 +273,7 @@ static void pan_disconnect_cb(DBusMessage *message, void *user_data) struct bluetooth_pan *pan; pan = g_hash_table_lookup(networks, path); - if (!pan) { + if (!pan || !pan->network) { DBG("network already removed"); return; } -- 2.11.0

Unable to establish a data connection on cdma network

by Nicolas ADELL

Hi all, We're using connman 1.31 to manage cdma network using a Cinterion modem. In particular cases, connman is uncapable to configuring the network. The current head branch leads to the same behavior. During its initialization, ofono broadcasts a 'PropertyChanged' signal notifying the addition of 'org.ofono.cdma.NetworkRegistration' as new interface. Connman catches this signal and requests its properties. Because, the interface 'org.ofono.cdma.ConnectionManager' is postponed immediately after the request, connman is not able to retrieve these properties because the pending call did not have received a reply yet. Jan 01 00:31:48 pcm connmand[470]: plugins/ofono.c:api_added() cdma-netreg added Jan 01 00:31:48 pcm connmand[470]: plugins/ofono.c:get_properties() /cinterionpxs8_0 path /cinterionpxs8_0 org.ofono.cdma.NetworkRegistration ... Jan 01 00:31:48 pcm connmand[470]: plugins/ofono.c:modem_changed() /cinterionpxs8_0 Interfaces 0x1b Jan 01 00:31:48 pcm connmand[470]: plugins/ofono.c:modem_update_interfaces() /cinterionpxs8_0 Jan 01 00:31:48 pcm connmand[470]: plugins/ofono.c:api_added() cmda-cm added Jan 01 00:31:48 pcm connmand[470]: plugins/ofono.c:get_properties() /cinterionpxs8_0 path /cinterionpxs8_0 org.ofono.cdma.ConnectionManager Jan 01 00:31:48 pcm connmand[470]: Pending GetProperties Jan 01 00:31:48 pcm connmand[470]: plugins/ofono.c:get_properties_reply() /cinterionpxs8_0 path /cinterionpxs8_0 org.ofono.cdma.NetworkRegistration Jan 01 00:31:48 pcm connmand[470]: plugins/ofono.c:cdma_netreg_properties_reply() /cinterionpxs8_0 Then, when ofono broadcasts a PropertyChanged signal into dbus system bus notifying its new ConnectionManager settings, no context list were created and connnman is trying to use a NULL list causing a segfault. Jan 01 00:31:55 pcm connmand[470]: plugins/ofono.c:get_properties() /cinterionpxs8_0 path /cinterionpxs8_0 org.ofono.cdma.NetworkRegistration Jan 01 00:31:55 pcm connmand[470]: plugins/ofono.c:cdma_cm_update_settings() /cinterionpxs8_0 Settings Jan 01 00:31:55 pcm connmand[470]: Aborting (signal 11) [/usr/sbin/connmand] The CDMA access technology does not require a context but connman needs to hold settings into a context. By modifying the cdma_cm_update_settings() function, we got a better behavior. First, by checking if a context exists to avoid the aborting situation. In case of missing context, verifying if a pending call is still waiting a reply and wait until the pending call is completed if necessary. Then, connman can send its request to ofono to get its ConnectionManager properties. I can work on a patch but that would be interesting if you could give me your opinion about the situation, confirm me that this is an actual issue, and not a misinterpretation of the code. Thanks, Regards, Nicolas

Create statistics file and service folder strictly only after successful connect

by Jose Blanquicet

Hi, We noticed that the service directory and the statistics file are created even if the connection is not successful because for example user entered an incorrect key. I think that it is because before starting the connection process, ConnMan tries to read the statistics file in service.c:service_connect(). Doing so, the function __connman_stats_service_register() will create the directory and the file if they do not exists. I saw that commit 50fb779bc95 already tried to solved this but it still happens. To solve this, I propose to either do the same of 50fb779bc95 in service_connect(): - if (__connman_stats_service_register(service) == 0) { + if (!service->new_service && + __connman_stats_service_register(service) == 0) { Or, maybe better, why ConnMan needs to access the file that early? Shouldn't it be done when service goes into CONFIGURATION state or READY state for new services? If it does not break any statistics feature, I would suggest to completely remove that piece of code from service_connect(): - if (__connman_stats_service_register(service) == 0) { - __connman_stats_get(service, false, - &service->stats.data); - __connman_stats_get(service, true, - &service->stats_roaming.data); - } What do yo think?
