[B.A.T.M.A.N.] Staging: batman-adv for 2.6.36 (6: fixes)
by Sven Eckelmann 09 Aug '10

09 Aug '10

Hi, here are patches targeted for 2.6.36. All patches needed for that patchset are already part of Linus' tree. They are smaller bugfixes and add no new features. The only special fix is "unify orig_hash_lock spinlock handling to avoid deadlocks" which fixes the usage of the same spinlock with spin_lock and spin_lock_irqsave. This one should also be applied in 2.6.35.x "Fix merge of linus tree" should readd an older bugfix again which was removed by your merge with Linus' tree. The patches for 2.6.37 will follow later. thanks, Sven Marek Lindner (4): Staging: batman-adv: unify orig_hash_lock spinlock handling to avoid deadlocks Staging: batman-adv: fix batman icmp originating from secondary interface Staging: batman-adv: always reply batman icmp packets with primary mac Staging: batman-adv: fix own mac address detection Sven Eckelmann (1): Staging: batman-adv: Fix merge of linus tree drivers/staging/batman-adv/bat_sysfs.c | 4 ++++ drivers/staging/batman-adv/hard-interface.c | 8 -------- drivers/staging/batman-adv/icmp_socket.c | 12 ++++++++---- drivers/staging/batman-adv/main.c | 7 +++++-- drivers/staging/batman-adv/originator.c | 14 ++++++++------ drivers/staging/batman-adv/routing.c | 16 ++++++++++++++-- drivers/staging/batman-adv/types.h | 1 + 7 files changed, 40 insertions(+), 22 deletions(-)

[B.A.T.M.A.N.] Problem openWRT "backfire" and "kmod-batman-adv"
by Tim 04 Aug '10

04 Aug '10

Hello, I'm trying to build an mesh network with B.A.T.M.A.N Advanced for my bachelor's thesis. Building an Image used to be no problem when the Batman-package was called "kmod-batman-adv-kernelland". Since there is only "kmod-batman-adv" in the OpenWRT repositories I have the following problem: Compiling, transferring and connecting is no problem, but after I change some settings in "/etc/config/network" and "/etc/config/wireless" and restart the router the power led keeps flashing and there's no possibility to connect to the device anymore. Only ping is working with the ip I set it to.... When doing only a network restart via /etc/init.d/network restart the device shows: "Segmentation fault" and then freezes. I tried compiling an Image on either 32 and 64 bit Ubuntu / Kubuntu. Do you have any suggestions? With best regards, Tim

[B.A.T.M.A.N.] [PATCH] batman-adv: Only copy skb data for multiple broadcasts
by Sven Eckelmann 03 Aug '10

03 Aug '10

batman-adv tries to resend broadcasts on all interfaces up to three times. For each round and each interface it must provide a skb which gets consumed by the sending function. It is unnecessary to copy the data of each broadcast because the actual data is either not shared or already copied by add_bcast_packet_to_list. So it is enough to just copy the skb control data Signed-off-by: Sven Eckelmann <sven.eckelmann(a)gmx.de> --- batman-adv/send.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/batman-adv/send.c b/batman-adv/send.c index cd6be2b..934bd8a 100644 --- a/batman-adv/send.c +++ b/batman-adv/send.c @@ -476,7 +476,7 @@ static void send_outstanding_bcast_packet(struct work_struct *work) rcu_read_lock(); list_for_each_entry_rcu(batman_if, &if_list, list) { /* send a copy of the saved skb */ - skb1 = skb_copy(forw_packet->skb, GFP_ATOMIC); + skb1 = skb_clone(forw_packet->skb, GFP_ATOMIC); if (skb1) send_skb_packet(skb1, batman_if, broadcast_addr); -- 1.7.1
