Your patch conflicts with patches waiting to be applied by Greg KH. I will redo your changes for the current and development version and submit them to the b.a.t.m.a.n. mailing list for further discussion. Is that ok for you? Best regards, Sven Eckelmann

[B.A.T.M.A.N.] reorganized kernel interface patches (version 3)
by Marek Lindner 05 Apr '10

05 Apr '10

Hi, since my last patches did not trigger too many complaints I went ahead and submitted them. This opens the way for the last series of patches which conclude the matter. All remaining /proc files have been eliminated and moved over to /sys. While doing so, I reworked the interface handling to satisfy an old feature request: interfaces can be added & removed on the fly. On startup batman-adv will scan the system for available interfaces to create a "batman_adv" subfolder in their respective /sys/class/net folder, e.g. eth0: /sys/class/net/eth0/batman_adv This subfolder will contain the settings which are relevant for this interface. You can tell batman-adv to use an interface by writing "bat0" into the mesh_iface file: echo bat0 > /sys/class/net/eth0/batman_adv/mesh_iface or write "none" to deactivate it: echo none > /sys/class/net/eth0/batman_adv/mesh_iface Although only "bat0" is accepted at this point, the syntax already gears towards multiple virtual mesh support. Later you will be able to create/name your virtual meshes by writing into this file. Retrieve the interface status by simply reading its status file: cat /sys/class/net/eth0/batman_adv/iface_status Note: batman-adv will continuously observe the system's interfaces. Whenever new interfaces appear or disappear batman will update the /sys/class/net folders automatically. Also, batman-adv will make sure that incompatible interfaces (e.g. loopback, non-ethernet, etc) won't have the subfolder, hence can't be activated. The batctl interface syntax had to be modified in order to cope with these changes. You can run: batctl interface to get the list of active interfaces and their status. To add or delete interfaces you can run: batctl interface add|del eth0 eth1 .. Since removing an active interface is a tricky thing where many operations can go wrong I expect some crashes/race conditions in the code. I tested it a while on multiple machines with multiple interfaces and it works for me but I'm sure there are more bugs to find. Regards, Marek

[B.A.T.M.A.N.] Minor change in vis.c
by Nathan Wharton 04 Apr '10

With the emphasis on minor. Could: printf("\"%s\" [label=\"%d.%d\"]\n", be: printf("\"%s\" [label=\"%d.%02d\"]\n", instead?

[B.A.T.M.A.N.] Problems connecting VPN and WLAN with Batman-adv
by Clemens John 04 Apr '10

04 Apr '10

Hi, I use batman advanced ("# batctl o" says "B.A.T.M.A.N. adv 0.2.1-beta r1578") on OpenWrt trunk and I have the following problem: I have a wlan meshnetwork in ahdemo mode which uses batman. The meshnetwork is used by clients without batman and therefore I have another network on the same wifi device in ad mode which is bridged with bat0. The bridge is in the network 10.18.1.0/24. I think its like described in http://www.open-mesh.org/wiki/batman-adv-quick- start-guide The problem is, that I have a vpn network on tap0 (10.18.0.0/24) and I dont know how I can link this two networks/interfaces to each other with batman. I tried to assign tap0 to batman, but this doesnt work. I want to be able to ping hosts that uses batman in the vpn and in the wlan network. How can I do this? My configs look like this: --------------- /etc/conf/network --------------- config 'interface' 'loopback' option 'ifname' 'lo' option 'proto' 'static' option 'ipaddr' '127.0.0.1' option 'netmask' '255.0.0.0' config 'interface' 'lan' option 'proto' 'dhcp' option 'ifname' 'eth0' config 'interface' 'mesh' option 'type' 'bridge' option 'ifname' 'ath0 bat0' option 'proto' 'static' option 'ipaddr' '10.18.1.101' option 'netmask' '255.255.255.0' config 'interface' 'vpn' option 'proto' 'none' option 'ifname' 'tap0' --------------- /etc/conf/wireless --------------- config wifi-device wifi0 option type atheros option channel 6 config wifi-iface option device wifi0 option mode ahdemo option bssid 02:CA:FF:EE:BA:BE config wifi-iface option device wifi0 option mode ap option ssid oldenburg.freifunk.net --------------- /etc/conf/batman-adv-kernelland --------------- config batman-adv-kernelland general option interface 'ath1 tap0' option originator_interval option log_level thanks Floh1111

[B.A.T.M.A.N.] Batman Advanced Internet Gateway
by Clemens John 02 Apr '10

02 Apr '10

Hi, on https://www.open-mesh.org/wiki/batman-adv stands, that the upcoming batman- adv 0.3 supports advanced gateway handling. We are testing Batman Advanced as described in my other thread and I want to share my Internetconnection on our network. How do I do this with Batman Advanced? Is there already a working Batman Advanced version that supports Internet connection sharing (Maybe Trunk? Which revision?)? In Olsr there was the dyn_gateway_plugin. How can I have something like it´s functionality in Batman Advanced? Thanks Floh1111
