You may want to set up IP addresses on the base Wi-Fi interfaces (e.g. wlan0) and try to ping between the nodes directly, without batman-adv. You may also check further with "iw wlan0 station dump" (or similar) who receives packets by whom, or check with tcpdump if you see the OGM broadcasts. I haven't seen many Realtek Wi-Fi devices to use batman-adv, and at least in the past my experience with those devices not very positive, so also for that reason I'd look into driver related issues first. Cheers, Simon

Fwd: Possibility of dual-licensing to ease bringing into FreeBSD
by obiwac 15 Sep '23

15 Sep '23

---------- Forwarded message --------- From: obiwac <obiwac(a)gmail.com> Date: Fri, 15 Sept 2023 at 16:10 Subject: Possibility of dual-licensing to ease bringing into FreeBSD To: mmokhi(a)FreeBSD.org <mmokhi(a)freebsd.org>, <imp(a)freebsd.org>, <jhb(a)freebsd.org> Hia, I recently ported batman-adv to FreeBSD as my GSoC project: https://wiki.freebsd.org/SummerOfCode2023Projects/CallingTheBatmanFreeNetwo… I'd like to bring this work into the FreeBSD source tree, but they are reluctant to bring in any new GPL code. Would it be possible to dual-license batman-adv to GPL/BSD, or would you rather not (in which case I'll ask FreeBSD's core@ if an exception could be made for batman-adv)? Thanks! Aymeric

batman 2023.1 fails to compile with implicit func kstrtou64 on debian 5.10.0
by MK 06 Sep '23

06 Sep '23

Hi list! I tried to compile batman-adv-2023.1 for a standard debian bullseye kernel 5.10.0-25 but it fails with: batman-adv/gateway_common.c:55:8: error: implicit declaration of function ‘kstrtou64’ [-Werror=implicit-function-declaration] 55 | ret = kstrtou64(buff, 10, &lthroughput); cc1: some warnings being treated as errors Tried make CFLAGS="-Wno-error=implicit-function-declaration" but that doesn't help. Successfully compiled on 5.15.0 (ubuntu LTS). Any ideas on this? Martin

[PATCH net] batman-adv: Hold rtnl lock during MTU update via netlink
by Sven Eckelmann 23 Aug '23

23 Aug '23

The automatic recalculation of the maximum allowed MTU is usually triggered by code sections which are already rtnl lock protected by callers outside of batman-adv. But when the fragmentation setting is changed via batman-adv's own batadv genl family, then the rtnl lock is not yet taken. But dev_set_mtu requires that the caller holds the rtnl lock because it uses netdevice notifiers. And this code will then fail the check for this lock: RTNL: assertion failed at net/core/dev.c (1953) Cc: stable(a)vger.kernel.org Reported-by: syzbot+f8812454d9b3ac00d282(a)syzkaller.appspotmail.com Fixes: c6a953cce8d0 ("batman-adv: Trigger events for auto adjusted MTU") Signed-off-by: Sven Eckelmann <sven(a)narfation.org> --- This problem was just identified by syzbot [1]. I hope it is ok to directly send this patch to netdev instead of creating a single-patch PR from the batadv/net branch. If you still prefer a PR then we can also prepare it.
