Package: bridge-utils Version: 1.5-9 Severity: important Dear Maintainer,
I have a server with 2 interfaces, bonded using 'bond_mode 802.3ad', on top of that I have a bridge device with a ipv4 and ipv6 address. Both interfaces are configured staticly. On first boot of the server I can ping6 the ipv6 address, if I leave the ping6 running there is no problems with ipv6 traffic. However if no ipv6 traffic is sent for a while, the it doesn't respond when I ping6 again. Looking at a tcpdump I can see the 'ICMP6, neighbor solicitation' requests being recieved on the physical interfaces, on the bond, but not on the bridge interface. I think this is exactly the same problem as http://patchwork.ozlabs.org/patch/326048/ As in the linked page the temporary fix is 'echo 0 > /sys/class/net/br0/bridge/multicast_snooping' As I understand it the resulting patch at http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/net/bridge/br_multicast.c?id=20a599bec95a52fa72432b2376a2ce47c5bb68fb needs backporting to this kernel. This behaviour first started around the 3.11 kernel which I ran as a backport into wheezy, I've never had the time to track down the issue until now. -- System Information: Debian Release: 8.1 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 3.16.0-4-amd64 (SMP w/2 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages bridge-utils depends on: ii libc6 2.19-18 bridge-utils recommends no packages.
