Re: [B.A.T.M.A.N.] Where do we stand on working systems?
by Jon Roland 20 Aug '10

20 Aug '10

How about descriptions of some of those systems: where they are, how well they work, how many nodes, how often used, what problems encountered and how solved, what they are being used for, who is on them. From all anyone can tell from reading this list, one might wonder whether all this is just conjecture about systems that don't exist anywhere.

[B.A.T.M.A.N.] [PATCH 1/9] batman-adv: Create batman_if only on register event
by Sven Eckelmann 20 Aug '10

20 Aug '10

We try to get all events for all net_devices to be able to add special sysfs folders for the batman-adv configuration. This also includes such events like NETDEV_POST_INIT which has no valid kobject according to v2.6.32-rc3-13-g7ffbe3f. This would create an oops in that situation. It is enough to create the batman_if only on NETDEV_REGISTER events because we will also receive those events for devices which already existed when we registered the notifier call.

[B.A.T.M.A.N.] Question about multiple GW scenario
by Antonio Quartulli 20 Aug '10

20 Aug '10

Hi guys, I'm writing a short report about the actual behaviour of b.a.t.m.a.n. in case of client roaming between bat-nodes. I was wondering what could happen in a particular (but not so unusual) situation: take a network made up of several nodes, and 2 IP gateways, say X and Y. These 2 gws are advertising themself as gw (via the gw-mode). Now we have two nodes A and B which respectively recognize as gw X and Y (A recognizes X and B recognizes Y, where recognize means "to have such gw as best gw"). Each gw runs a dhcp server which assigns itsself as default ip route. Now, what would it happen if a client roams from A to B and sends a new dhcp request (cause the lease time has expired) so changing the default gw from X to Y? The established connections will stop to work. I think that this is a classical level 3 issue in the hand-off procedure. What do you think about this problem? Am I missing something? Thank you all :) -- Antonio Quartulli ..each of us alone is worth nothing.. Ernesto "Che" Guevara

Yes, let's switch back to the ml. The the bug can be checked more easily now. The problem is that the compiler optimizes it a little bit.... too much. So the backtrace isn't always clear. If I understand the output (and the output of Lemonde) correctly then we have the problem with the changeaddr event and not the mtu update as the backtrace would suggest. Now it really makes fun again to debug those things :D I haven't wrote that code... so it may take a little bit until I feel in the right mood to hunt it real down. Thanks a lot for your help in debugging it. Your name will definitely appear in the kernel changelog. @Lemonde, it seems that you have the same problem. The patch will appear on the ml later. But please also add the other patches I'd suggested. Greetings, Sven

Hello, sorry I didn't notice the two other patches Marek sent. So as you noticed I only tested the first patch. I recompiled the batman-package with the two new patches integrated. I repeated the steps I did with the last patch: 1) I patched the Batman-Package. 2) I uninstalled the old package and rebooted the device. 3) I transferred the new Batman package onto the device via scp, installed the package and restarted again. 4) I checked wether batman is running using lsmod: It is.... 5) I checked the return of "batctl if" and got no return. Then I checked: "root@OpenWrt:~# batctl o BATMAN mesh bat0 disabled - please specify interfaces to enable it" Then I continued in several ways, and noticed that the error can occure at different events. To keep it most realistic I not only enabled radio0, but changed the mode to adhoc: "/etc/config/wireless: config wifi-device radio0 option type mac80211 option channel 5 option macaddr 00:25:9c:3c:46:06 option hwmode 11g config wifi-iface option device radio0 option mode adhoc option ssid OpenWrt option encryption none" Then I restarted the network, without an error. This also doesn't show an error, when keeping the mode on "ap". root@OpenWrt:~# /etc/init.d/network restart udhcpc (v1.15.3) started Sending discover... root@OpenWrt:~# Sending discover... Sending discover... Then I tried serveral ways to continue, which all end in segmentation faults, wehen doing network restarts or freezing the device when rebooting. Here is a list of what I tried: - Adding wlan0 to batman-interface (although it already is in the config file, it only shows in batctl after adding it with "batctl if add wlan0") and then doing ab network restart - Just doing a reboot, the device freezes on startup. - Adding an wlan interface in /etc/config/network/ with an mtu of 1524 and then restarting the network. here is the dmesg and logread for that situation: root@OpenWrt:~# dmesg Linux version 2.6.32.16 (tim@atze) (gcc version 4.3.3 (GCC) ) #1 Thu Aug 12 14:49:00 CEST 2010 CPU revision is: 00029008 (Broadcom BCM3302) ssb: Core 0 found: ChipCommon (cc 0x800, rev 0x0E, vendor 0x4243) ssb: Core 1 found: Fast Ethernet (cc 0x806, rev 0x09, vendor 0x4243) ssb: Core 2 found: MIPS 3302 (cc 0x816, rev 0x06, vendor 0x4243) ssb: Core 3 found: USB 1.1 Host (cc 0x817, rev 0x02, vendor 0x4243) ssb: Core 4 found: MEMC SDRAM (cc 0x80F, rev 0x01, vendor 0x4243) ssb: Core 5 found: IEEE 802.11 (cc 0x812, rev 0x09, vendor 0x4243) ssb: Core 6 found: Roboswitch (cc 0x81C, rev 0x02, vendor 0x4243) ssb: Initializing MIPS core... ssb: set_irq: core 0x0806, irq 4 => 4 ssb: set_irq: core 0x0816, irq 5 => 2 ssb: set_irq: core 0x0812, irq 2 => 5 ssb: after irq reconfiguration ssb: core 0x0800, irq : 2(S) 3* 4 5 6 D I ssb: core 0x0806, irq : 2(S) 3 4* 5 6 D I ssb: core 0x0816, irq : 2(S)* 3 4 5 6 D I ssb: core 0x0817, irq : 2(S) 3 4 5 6* D I ssb: core 0x080f, irq : 2(S) 3 4 5 6 D I* ssb: core 0x0812, irq : 2(S) 3 4 5* 6 D I ssb: core 0x081c, irq : 2(S) 3 4 5 6 D I* ssb: Sonics Silicon Backplane found at address 0x18000000 Serial init done.

Hello, sorry for not respoing over the weekend, but I had no hardware to do the testing. So here is what I did: 1) I patched the Batman-Package. 2) I uninstalled the old package and rebooted the device. 3) I transferred the new Batman package onto the device via scp, installed the package and restarted again. 4) I checked wether batman is running using lsmod: It is.... 5) I checked the return of "batctl if" and got no return. Then I checked: "root@OpenWrt:~# batctl o BATMAN mesh bat0 disabled - please specify interfaces to enable it" The batman-config file does have wlan0 as an interface, although. 6) I enabled radio0 by removing "option disabled 1" and restarted the network. Here is what the Terminal showed: root@OpenWrt:~# /etc/init.d/network restart udhcpc (v1.15.3) started Sending discover... Configuration file: /var/run/hostapd-phy0.conf Using interface wlan0 with hwaddr 00:25:9c:3c:46:06 and ssid 'OpenWrt' Sending discover... root@OpenWrt:~# Sending discover... 7) After that I rebooted the whole device, but during booting the device freezes again. But in contrast to before, the led which indicated wlan being active, flashes for a short moment. Then I repated the test doing the steps 2-6. After that I did the following steps: "root@OpenWrt:~# batctl if root@OpenWrt:~# batctl o BATMAN mesh bat0 disabled - please specify interfaces to enable it root@OpenWrt:~# batctl if add wlan0 root@OpenWrt:~# batctl if wlan0: active root@OpenWrt:~# /etc/init.d/network restart Received SIGTERM Entering released state udhcpc (v1.15.3) started ifconfig: mon.wlan0: error fetching interface information: Device not found Sending discover... Configuration file: /var/run/hostapd-phy0.conf Segmentation fault Failed to start hostapd for phy0 root@OpenWrt:~# Sending discover...

[B.A.T.M.A.N.] [PATCH] batman-adv: Create batman_if only on special events
by Sven Eckelmann 14 Aug '10

14 Aug '10

We try to get all events for all net_devices to be able to add special sysfs folders for the batman-adv configuration. This also includes such events like NETDEV_POST_INIT which has no valid kobject according to v2.6.32-rc3-13-g7ffbe3f. This would create an oops in that situation. We also drop NETDEV_UNREGISTER as event which may register a new batman_if because it would be destroyed after its initialisation.

Re: [B.A.T.M.A.N.] Problem openWRT "backfire" and "kmod-batman-adv"
by Tim 11 Aug '10

Hello, first of all I'd like to say thanks for your fast replies. I'm not very used to using Linux so this is a little tricky to me. First of all I'm going to show you the way I compiled an image containing batman-adv (that's the way it used to work before) for WRT54GL: Step1: Check out the backfire repository: "svn co svn://svn.openwrt.org/openwrt/branches/backfire" Step2: Change to backfire-folder "cd backfire" Step3: Adding the Batman-Adv module "./scripts/feeds update" "./scripts/feeds install kmod-batman-adv" Step4: Configure the Image using: "make menuconfig" Here I select "Broadcom BCM947xx/953xx" with 2.6 kernel as Target System and add the batman-package in "Image Configuration - > Kernel Modules -> Network Support" Step4: Compiling the Image Step5: Transferring the image, changing the password via telnet and the connecting via SSH Step6: Editing the config files using uci: "root@OpenWrt:~# uci delete wireless.radio0.disabled root@OpenWrt:~# uci delete wireless.(a)wifi-iface[0].network root@OpenWrt:~# uci set wireless. radio0.channel=1 root@OpenWrt:~# uci set wireless.(a)wifi-iface[0].mode=adhoc root@OpenWrt:~# uci set wireless.(a)wifi-iface[0].ssid=mesh root@OpenWrt:~# uci set wireless.@wifi-iface[0].bssid=02:12:34:56:78:9A root@OpenWrt:~# uci set network.lan.mtu=1500 root@OpenWrt:~# uci set network.lan.ifname="eth0.0 bat0" root@OpenWrt:~# uci set network.wlan0=interface root@OpenWrt:~# uci set network.wlan0.ifname=wlan0 root@OpenWrt:~# uci set network.wlan0.proto=none root@OpenWrt:~# uci set network.wlan0.mtu=1524 root@OpenWrt:~# uci set network.bat0=interface root@OpenWrt:~# uci set network.bat0.ifname=bat0 root@OpenWrt:~# uci set network.bat0.proto=none root@OpenWrt:~# uci set network.bat0.mtu=1500 root@OpenWrt:~# uci commit root@OpenWrt:~# /etc/init.d/network restart" After restarting the network the console says: "segmentation fault" and freezes. When doing "reboot" instead the device also freezes and the power-led keeps flashing. I also tried only changing the config in /etc/config/wireless and restarted the device, with the same effect. In order to make sure the error isn't related to any errors while compiling the image, I compiled an Image without the batman-adv package. After that I was able to configure the router as usual without any freezes. As I already mentioned I'm not very used to Linux, so I have not yet found a way to connect to the router with serial console without building an JTAG-Cable. Is that right? Greetings, Tim
