[B.A.T.M.A.N.] [PATCH 1/3] alfred: Check if tg hash was really initialized
by Sven Eckelmann 01 Jun '17

01 Jun '17

The return value check after the tg_hash_new call must actually check the return value and not some other datastructure.

[B.A.T.M.A.N.] MAC addresses of loop detect frames in global translation-table
by Andreas Pape 01 Jun '17

01 Jun '17

Hello, I stumbled across some weired MAC addresses starting with ba:be in the global translation-table when running batman-adv-2017.0.1. I run my setup with bla enabled. Most of the entries in the global tt of my devices consist of these mac addresses. Looking through the code they come from frames which seem to be used for loop detection. Adding such MAC addresses to the local tt is prevented with the help of the batadv_bla_is_loopdetect_mac function. I wonder why adding these macs to the global tt is not prevented in a simliar way. Would it be possible to add a corresponding check to batadv_tt_global_add to prevent these macs from being added to the global tt? Or is there a specific reason why these mac addresses must occur in the global tt and which I have not understood so far?

[B.A.T.M.A.N.] [PATCH 0/5] alfred: TQ query optimizations
by Sven Eckelmann 01 Jun '17

01 Jun '17

Hi, alfred uses the TQ from batman-adv to find its best alfred neighbor. This best neighbor information is used by slave servers to request/publish data. This is done for each server announcement packet by: * requesting the global translation table (netlink or debugfs) and then searching in it for the MAC address of the detected alfred server to find its originator address * requesting the originator table (netlink or debugfs) and then searching it it for the originator address of the detected alfred server to find its TQ value This was previously done whenever a new announcement packet received by alfred. We've observed that this can be a problem on networks with a lot of master servers (~100) which can see each other, large translation tables and slow CPUs. alfred still worked but the CPU load by alfred was rather high (~20% on an 560MHz AR9344). The idea is now to avoid this lookup for master servers. And (for slave servers) to process all servers at once. This is done before the wants to push its local data to a master server in an sync interval. The process which was described earlier was now changed to: * requesting the global translation table (netlink or debugfs) and then put MAC address and corresponding originator address in tg hash * requesting the originator table (netlink or debugfs) and then put originator address and corresponding TQ value orig hash * got through all servers: - search in tg hash for for the MAC address of the alfred server to find its originator address - search in orig hash for for the originator address of the alfred server to find its TQ value These changes reduced the load on the previously mentioned devices significantly. Kind regards, Sven Sven Eckelmann (5): alfred: Move alfred specific netlink code in separate file alfred: Only query tq of remote master in slave mode alfred: Check the TQ of master servers before pushing data alfred: Cache the TQ values for each originator alfred: Cache the global translation table entries Makefile | 1 + alfred.h | 1 - batadv_query.c | 227 +++++++++++++++++++++++++++++++++++++++++-------------- batadv_query.h | 25 +++++- batadv_querynl.c | 216 ++++++++++++++++++++++++++++++++++++++++++++++++++++ batadv_querynl.h | 34 +++++++++ netlink.c | 195 ----------------------------------------------- netlink.h | 7 -- recv.c | 15 +--- server.c | 56 +++++++++++++- 10 files changed, 501 insertions(+), 276 deletions(-) create mode 100644 batadv_querynl.c create mode 100644 batadv_querynl.h

Hi, Thought it might be a good idea to collect the topics we could/should discuss or work on at the BattleMesh in Vienna concerning B.A.T.M.A.N. I started with a list of things I'd be interested in in the link below - feel free to add yours, too: https://etherpad.wikimedia.org/p/batman-wbm10 Regards, Linus PS: If you are adding discussion topics, ideally you'd be in Vienna, too ;).

[B.A.T.M.A.N.] [PATCH] batman-adv: Print correct function names in dbg messages
by Sven Eckelmann 23 May '17

23 May '17

The function names in batman-adv changed slightly in the past. But some of the debug messages were not updated correctly and therefore some messages were incorrect. To avoid this in the future, these kind of messages should use __func__ to automatically print the correct function name.

by Sven Eckelmann 19 May '17

19 May '17

The stats are generated by batadv_interface_stats and must not be stored directly in the net_device stats member variable. The batadv_priv bat_counters information is assembled when ndo_get_stats is called. The stats previously stored in net_device::stats is then overwritten. The batman-adv counters must therefore be increased when an ARP packet is answered locally via the distributed arp table.

[B.A.T.M.A.N.] Memory leakage
by Andreas Pape 19 May '17

19 May '17

Hi, as far as I could figure out via bisect commit [1] causes a memory leakage as the way how skbs are consumed / freed has been changed since I first developed this patch. This happens in a setup using bla and when the mesh links between mesh nodes sharing a common backbone become very weak and unstable. I think the line with the "return NET_RX_DROP;" needs to be replaced by "goto skb_free;". How is the correct procedure to change this? As this patch has already been committed to the git repo I guess I should send a new patch or is a new version of the old patch necessary?
