On linux with stable kernel v3.4.39, when this patch (ipv6: fix bad free

1. the default value of ipv6 forwarding is 0
2. we change it to 1 firstly via:
# vi /etc/sysctl.conf
Uncomment: net.ipv6.conf.all.forwarding=1
#sysctl –p
Then we can verify via
#sysctl –a | grep forwarding
3, then we create a new namespace via:
# ip netns add fib_100
# ip netns exec fib_100 sysctl -a | grep forwarding
We’ll see in this new name space, the value of ipv6 forwarding will be
set to ‘1’ in v3.4.38, but in v3.4.39, the value is still be ‘0’
without this patch (ipv6: fix bad free of addrconf_init_net), the value
of ipv6 forwarding will be set to ‘1’.
Would you like to tell me which one (v4.3.39 and v4.3.38) is correct?
Best Regards!
