[B.A.T.M.A.N.] openwrt config changes when upgrading from 2014-4 to 2015-0 ?
by Ufo 13 Jun '15

13 Jun '15

thank you for upgrading batman-adv inside openwrt trunk to 2015-0 im testing new version (yesterdays openwrt trunk) but have problems: the bridge (br-mesh12) with bat-interface and wifi-vAP isnt complete, the bat-interface is missing :-( the "wifi" command also doesnt repair that :-( but, when i delete vlan-setting (for interface, where batman-adv is running on) problems are gone. maybe config for openwrt/batman-adv has changed, or some of our settings are outdated and now obsolete? ufo p.s. with 10 days old openwrt trunk (and batman-adv 2014-4) the problem doesnt appear p.p.s. maybe my former firmware problems are related to that? some of them are gone when we only use one batman-adv on each node instead of two https://github.com/freifunk/meshkit-firmware/issues/23 https://github.com/freifunk/meshkit-firmware/issues/12 ---- tested with minimalized setup it looks like this: some config-files... config interface 'wireless0' option dns '8.8.8.8 212.204.49.83 141.1.1.1' option netmask '255.255.255.255' option proto 'static' option ipaddr '10.61.234.70' option mtu '1536' config interface 'mesh12' option type 'bridge' option ifname 'bat12' option proto 'none' config interface 'meshbat12' option ifname '@wireless0.12' option proto 'batadv' option mesh 'bat12' option mtu '1532' ------ config wifi-device 'radio0' option type 'mac80211' option path 'platform/ar934x_wmac' option htmode 'HT20' option diversity '1' option distance '1000' option disabled '0' option country 'DE' option channel '44' option hwmode '11na' config wifi-iface 'radio0_iface' option device 'radio0' option encryption 'none' option mode 'adhoc' option mcast_rate '6000' option network 'wireless0' option ssid 'leipzig.freifunk.net' option bssid '02:44:CA:FF:EE:EE' config wifi-iface 'radio0_meshap12' option network 'mesh12' option mode 'ap' option device 'radio0' option encryption 'none' option ssid '012Freifunk-Test' root@234-70:~# cat /etc/config/batman-adv config mesh 'bat12' option gw_mode 'client' option multicast_mode '0' option bridge_loop_avoidance '1' ---- root@234-70:~# brctl show bridge name bridge id STP enabled interfaces br-mesh12 7fff.16cc204886e0 no wlan0-1 ----------------------------- ############################# changing to test setting, its working in a proper way: config interface 'meshbat12' option ifname '@wireless0' option proto 'batadv' option mesh 'bat12' option mtu '1532' --- root@234-70:~# brctl show bridge name bridge id STP enabled interfaces br-mesh12 7fff.16cc204886e0 no wlan0-1 bat12 -- --- Freifunk Leipzig http://leipzig.freifunk.net

[B.A.T.M.A.N.] Mesh hickups with 2014.3
by Bjoern Franke 12 Jun '15

12 Jun '15

Hi, in the last days we upgraded nearly all (~500) routers of our Freifunk -mesh from 2013.4 to 2014.3. The most things run fine again, but with some routers we have connectivity issues as follows: - gateway gets alfreddata from router - router pingable via batctl - ping via linklocal, ULA and public-IPv6 from gateway to router not possible - other routers in the same mesh can ping it via ULA etc (connected via the same fastd-VPN) Public-IPv6 is announced from a gateway via radvd into the mesh. Unfortunately we are out of ideas where we can search for the reason. Regards bjo -- xmpp bjo(a)schafweide.org

[B.A.T.M.A.N.] [PATCH] batman-adv:Remove unnessary break statements for switch statement in the function batadv_bla_proccess_claim
by Nicholas Krause 11 Jun '15

11 Jun '15

This removes the unnessary break statements for the switch statement in the function, batadv_blav_procces_claim for checking the structure pointer, bla_dst's variable member, type due to returning directly for the cases in this switch if they evaluate to be equal to the value of the member variable type of the structure pointer, bla_dst and thus no need to avoid fallthrough with break statements in this particular switch statement.

(s|u)(8|16|32|64) are the preferred types in the kernel. The use of the standard C99 types u?int(8|16|32|64)_t are objected by some people and even checkpatch now warns about using them.

[B.A.T.M.A.N.] [OT] support batman-based networks in Argentina
by Nicolás Echániz 10 Jun '15

10 Jun '15

Hi guys, long time without posting on the list, and now I'm sending this Off Topic... shame ! Anyway... I wanted to let you all know that we have presented AlterMundi networks for the FRIDA Awards 2015. It's a prize organized by LACNIC, the Latin American RIR. There is one prize slot open for public election and we are doing so well on that front that we are aiming for it. We are head to head with another project and today is the last day for online voting, so you are all invited to stop by http://programafrida.net/projects/projects/view/869 ...and cast your vote. It just takes a few seconds! The project is written in Spanish but there's enough info in English about our work in cas you are not familiar with it. @marek: we are finally creating the inter-town network (6 towns actually), to deploy our batman+bmx6 design (Libre-Mesh). We'll have news on this during the next few months. If you wish to share this with other people, there's a 2min. video that you can use to that end: http://youtu.be/4SgVq7e40P4 Thanks for reading and for the support! Cheers, Nico

[B.A.T.M.A.N.] TVLV infrastructure (v2)
by Marek Lindner 10 Jun '15

10 Jun '15

Hi, at the battlemesh we had plenty of time to discuss and test the tvlv patchset. Therefore, a number of changes/fixes found their way into v2 touching the tvlv API, network coding, unicast sending and gateway announcements. This looks like the final version which is going to be merged unless objections are raised soon-ish. Cheers, Marek

This is the fourteenth revision of the basic multicast optimization patches. Changes in v14 include: * fixed compilation for CONFIG_BATMAN_ADV_MCAST=n (issue was introduced by v13) * fixed potential null pointer exception (moved ethhdr assignment in batadv_mcast_forw_mode() to after the check methods / pskb_may_pull()s) * removed flag-list-"helper" functions * removed methods which were performing both counting and orig_node retrieval in batadv_mcast_forw_mode(), instead doing that in two logical, seperate sections in batadv_mcast_forw_mode() Cheers, Linus
