[B.A.T.M.A.N.] Replacing OLSRD with batman-adv?
by tjhowse 08 Nov '13

08 Nov '13

Hi Ladies and Gents, I've built a three-node mesh network using cheap TP-Link TL-WDR3600 routers. They can do simultaneous 5.8GHz and 2.4GHz. I use the 5.8 for the backbone links between the nodes, and 2.4 to clients. The nodes are running OpenWRT and OLSRD. This system mostly works well, but there are a couple of problems with it that I'm wondering if batman-adv would solve or make easier to solve: 1) The backbone links cannot be better protected than WEP, a limitation of OLSRD, 2) Gateway assignment is a manual process, which must be performed on every node in the mesh, referring to the single node connected to the WAN, 3) The manual gateway configuration of 2) prevents peer-to-peer communications between mesh clients, 4) Each node has its own /24 subnet. This causes problems when a device roams from one device's jurisdiction to another if the interface doesn't re-issue a DHCP request. We're expanding the network, I've just bought another ten of these routers, and I'm going to spend some time assessing if batman-adv would be a better fit for our purposes. There will be a range of ios, android and windows devices connecting to the mesh. My questions are as follows: 1) Does batman-adv worth with WPA2 or better encryption? 2) Must every client to a batman-adv mesh have a daemon installed? 3) Is it possible to separate different radio interfaces for different purposes? I.E. 5.8 for backbone, 2.4 for clients. 4) Can all nodes and clients on a mesh have an IP in the same subnet, solving some of the roaming problems caused by bad interface settings or drivers? Thanks, Travis.

[B.A.T.M.A.N.] Documentation of packet types
by Ruben Kelevra 06 Nov '13

06 Nov '13

Hi, I've been searching on your website, but I cant find the packet type documentation. The only definition I found was this[1] for clientroaming. Is there a documentation of the latest compatv. 14 out there? [1] http://www.open-mesh.org/projects/batman-adv/wiki/Client-roaming Best Regards, Ruben

[B.A.T.M.A.N.] [PATCHv2 0/8] add network wide multi interface optimization
by Simon Wunderlich 05 Nov '13

05 Nov '13

This patchset adds the network wide multi interface optimization as proposed in our wiki [1] for BATMAN IV. The main purpose is to do interface alternating and bonding by considering multi interface capabilities globally and not just for the (next) link, otherwise non-optimal links may be chosen. This patchset needs to change a lot of core data structures and routing, please review it carefully. A local development branch exists on the public git repo [2]. Changes from PATCH series earlier this month (thanks Marek and Antonio for suggestions) are: * change locking from implicit rcu locking to refcount based locking * add debugfs folder for hardif (new patch 7) and use separate tables per interface * split *ifinfo_get() functions into ifinfo_new() and ifinfo_get() * simplify function names and change to new naming scheme * review bonding locking * various kerneldoc/style/comment improvements * rebase on latest master * ... and some more in the changelog of the individual patches I've tested the patchset in my VMs to confirm that bonding and alternating works as expected. Patches should be checkpatch and sparse clean. As always, any comments are appreciated!

This is the tenth revision of the basic multicast optimization patches. No changes were made except dealing with two or three rebase conflicts while rebasing on top of 24c51de20. Cheers, Linus

[B.A.T.M.A.N.] [PATCHv2 1/2] batman-adv: deselect current GW on client mode switch off
by Antonio Quartulli 05 Nov '13

05 Nov '13

From: Antonio Quartulli <antonio(a)open-mesh.com> When switching from gw_mode client to either off or server the current selected gateway has to be deselected. In this way when client mode is enabled again a gateway re-election is forced and a GW_ADD event is consequently sent. The current behaviour instead is to keep the current gateway leading to no GW_ADD event when gw_mode client is selected for a second time Signed-off-by: Antonio Quartulli <antonio(a)open-mesh.com> --- Patch 2/2: - rename gw_deselect to gw_reselect in gw_client.h Cheers, gateway_client.c | 4 ++++ sysfs.c | 9 +++++++++ 2 files changed, 13 insertions(+) diff --git a/gateway_client.c b/gateway_client.c index 2449afa..2903bdb 100644 --- a/gateway_client.c +++ b/gateway_client.c @@ -207,6 +207,10 @@ void batadv_gw_check_client_stop(struct batadv_priv *bat_priv) if (!curr_gw) return; + /* deselect the current gateway so that next time that client mode is + * enabled a proper GW_ADD event can be sent */ + batadv_gw_select(bat_priv, NULL); + /* if batman-adv is switching the gw client mode off and a gateway was * already selected, send a DEL uevent */ diff --git a/sysfs.c b/sysfs.c index 6335433..d1765fd 100644 --- a/sysfs.c +++ b/sysfs.c @@ -408,6 +408,15 @@ static ssize_t batadv_store_gw_mode(struct kobject *kobj, batadv_info(net_dev, "Changing gw mode from: %s to: %s\n", curr_gw_mode_str, buff); + /* invoking batadv_gw_deselect() is not enough to really de-select the + * current GW.

[B.A.T.M.A.N.] [PATCH] batman-adv: remove FSF address from GPL disclaimer
by Antonio Quartulli 05 Nov '13

05 Nov '13

As suggested by checkpatch, remove all the references to the FSF address since the kernel already has one reference in its documentation. In this way it is easier to update it in case of future changes.

[B.A.T.M.A.N.] [PATCHv2 1/2] batman-adv: deselect current GW on client mode switch off
by Antonio Quartulli 04 Nov '13

04 Nov '13

From: Antonio Quartulli <antonio(a)open-mesh.com> When switching from gw_mode client to either off or server the current selected gateway has to be deselected. In this way when client mode is enabled again a gateway re-election is forced and a GW_ADD event is consequently sent. The current behaviour instead is to keep the current gateway leading to no GW_ADD event when gw_mode client is selected for a second time Signed-off-by: Antonio Quartulli <antonio(a)open-mesh.com> --- Changes from v1: * Introduce patch 2 to rename batadv_gw_deselect() * add big fat comment in 1/2 that explain why invoking batadv_gw_deselect() is not enough to really deselect the current GW Cheers, gateway_client.c | 4 ++++ sysfs.c | 9 +++++++++ 2 files changed, 13 insertions(+) diff --git a/gateway_client.c b/gateway_client.c index 2449afa..2903bdb 100644 --- a/gateway_client.c +++ b/gateway_client.c @@ -207,6 +207,10 @@ void batadv_gw_check_client_stop(struct batadv_priv *bat_priv) if (!curr_gw) return; + /* deselect the current gateway so that next time that client mode is + * enabled a proper GW_ADD event can be sent */ + batadv_gw_select(bat_priv, NULL); + /* if batman-adv is switching the gw client mode off and a gateway was * already selected, send a DEL uevent */ diff --git a/sysfs.c b/sysfs.c index 6335433..d1765fd 100644 --- a/sysfs.c +++ b/sysfs.c @@ -408,6 +408,15 @@ static ssize_t batadv_store_gw_mode(struct kobject *kobj, batadv_info(net_dev, "Changing gw mode from: %s to: %s\n", curr_gw_mode_str, buff); + /* invoking batadv_gw_deselect() is not enough to really de-select the + * current GW.

[B.A.T.M.A.N.] alfred hook to run when new information is received?
by Gui Iribarren 04 Nov '13

04 Nov '13

Hey Simon, until sarcasmarec ideas come true... ;) [(2013/10/14) marec: d0tslash: we should release some more daemons] we're doing our best to convince current daemons to turn *more* evil, in the meanwhile turns out, we're trying to propagate dnsmasq dhcp leases over the network with alfred [1]: http://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2013q4/007750.html with the current 'alfred-facters' 5-minute cronjob (or any cronjob, yeah) we can send a reload signal to dnsmasq at an acceptably short interval. Nevertheless, something more realtime would be highly desirable in this case some kind of hook inside the C code, that gets called when alfred gets updated information from any other node, and the hook runs a script (or maybe all facters in facters_dir?) in other words, instead of polling alfred every X interval to see if there's any new info, make alfred react as soon as it receives propagated info, so that it calls facter scripts and they can use that info ASAP. What do you think? Sounds useless? doable? Lightweight? Almighty? gui :)
