| H A D | netfilter_ipv6.h | efb6de9b Sat May 30 08:30:16 CDT 2015 Bernhard Thaler <bernhard.thaler@wvnet.at> netfilter: bridge: forward IPv6 fragmented packets
IPv6 fragmented packets are not forwarded on an ethernet bridge
with netfilter ip6_tables loaded. e.g. steps to reproduce
1) create a simple bridge like this
modprobe br_netfilter
brctl addbr br0
brctl addif br0 eth0
brctl addif br0 eth2
ifconfig eth0 up
ifconfig eth2 up
ifconfig br0 up
2) place a host with an IPv6 address on each side of the bridge
set IPv6 address on host A:
ip -6 addr add fd01:2345:6789:1::1/64 dev eth0
set IPv6 address on host B:
ip -6 addr add fd01:2345:6789:1::2/64 dev eth0
3) run a simple ping command on host A with packets > MTU
ping6 -s 4000 fd01:2345:6789:1::2
4) wait some time and run e.g. "ip6tables -t nat -nvL" on the bridge
IPv6 fragmented packets traverse the bridge cleanly until somebody runs.
"ip6tables -t nat -nvL". As soon as it is run (and netfilter modules are
loaded) IPv6 fragmented packets do not traverse the bridge any more (you
see no more responses in ping's output).
After applying this patch IPv6 fragmented packets traverse the bridge
cleanly in above scenario.
