Hi, I would like to propose following patches for net-next-2.6/2.6.40. They include minor cleanups of comments, a big rename patch s/hna/tt/, but also a remove some duplicated code. The spinlock which protected the list of possible interfaces for batman-adv was completely replaced by rtnl_lock because we want to be in sync with the rest of the network stack and the extra spinlock made everything more complex without giving any additional feature (and rtnl_lock was already used everywhere). Related to this patch is also a fix which should prevent a deadlock between the sysfs code and the event listener. Also the reference counting in find_router was fixed when an error was detected after the refcounter was already increased. The only feature is the support for multiple vlans in the bridge loop detection code. I will submit a patch to remove the atomic_dec_not_zero from main.h after Linus accepted the patch you already saw. thanks, Sven The following changes since commit 32ae9b221e788413ce68feaae2ca39e406211a0a: batman-adv: Make bat_priv->primary_if an rcu protected pointer (2011-05-01 22:49:03 +0200) are available in the git repository at: git://git.open-mesh.org/ecsv/linux-merge.git batman-adv/next Antonio Quartulli (1): batman-adv: rename everything from *hna* into *tt* (translation table) Daniele Furlan (1): batman-adv: remove duplicate code from function is_bidirectional_neigh() Marek Lindner (3): batman-adv: remove misplaced comment batman-adv: multi vlan support for bridge loop detection batman-adv: Fix refcount imbalance in find_router Sven Eckelmann (3): batman-adv: Remove unnecessary hardif_list_lock batman-adv: Avoid deadlock between rtnl_lock and s_active batman-adv: Remove multiline comments from line ending Documentation/networking/batman-adv.txt | 11 +- net/batman-adv/aggregation.c | 16 +- net/batman-adv/aggregation.h | 4 +- net/batman-adv/bat_debugfs.c | 4 +- net/batman-adv/bat_sysfs.c | 16 +- net/batman-adv/hard-interface.c | 36 +-- net/batman-adv/main.c | 20 +- net/batman-adv/main.h | 42 ++-- net/batman-adv/originator.c | 10 +- net/batman-adv/packet.h | 5 +- net/batman-adv/routing.c | 162 ++++++------- net/batman-adv/routing.h | 6 +- net/batman-adv/send.c | 16 +- net/batman-adv/send.h | 2 +- net/batman-adv/soft-interface.c | 409 +++++++++++++++++++++--------- net/batman-adv/translation-table.c | 417 ++++++++++++++++--------------- net/batman-adv/translation-table.h | 24 +- net/batman-adv/types.h | 49 +++-- net/batman-adv/unicast.c | 2 +- net/batman-adv/vis.c | 18 +- 20 files changed, 712 insertions(+), 557 deletions(-)

[B.A.T.M.A.N.] Routing improvement taking into account links bit-rate
by Daniele Furlan 08 May '11

08 May '11

Hi all, as anticipated some weeks ago, I'm working on a modification of B.A.T.M.A.N. routing metric in order to take into account link bit-rate. As already exposed, in my opinion, it is important to consider bit-rate because there isn't any correlation between TQ and the physical capacity. I have called the new metric PCE (Physical Capacity Estimation), which is defined for each path as the minimum value of (tq_local * bit-rate) among all the link forming it. After a quick and dirty modification of the code, I've done some test on two simple topologies to verify whether there is an improvement or not. From this preliminary test seems that the improvement is remarkable. In the attached report there is a better explanation of the modification, and the results from the tests. Any comment will be appreciated!! Regards. -- Daniele Furlan

[B.A.T.M.A.N.] [PATCH 1/2] batman-adv: Don't include bat_sysfs.h in compat.h
by Sven Eckelmann 08 May '11

08 May '11

bat_sysfs.h is included in compat.h to provide bat_attribute which is used in bat_wrapper_show and bat_wrapper_store. This could create a include loop which prevents that functions or datastructures defined elsewhere cannot be found in bat_sysfs.h when batman-adv gets compiled as external module, but are available when it is used as in-kernel module.

Why is one of the previous ones better then... lets say olsr or babeld. Do you want mesh for the backbone or for the actual clients? Do you want to use multiple interfaces? Why don't you use already existing solutions? What kind of router do you use? What do you mean by open ssid? How do you think is a ssid and wpa are related? What is a "ssid by MAC addresses"? Do you know what IBSS is? Why is a dns provider relevant? Are you able to build OpenWRT? Do you know what an OpenWRT feed is? Do you know how to build packages through OpenWRT feeds and integrate them in a OpenWRT image? Kind regards, Sven
