Hello,
Is it possible to use Netfilter to hook the packets on 6LowPan?
I tryied 2 different configurations:
1)
netfilter_ops.hook = main_hook;
netfilter_ops.pf = PF_INET6;
netfilter_ops.hooknum = NF_IP6_PRE_ROUTING;
netfilter_ops.priority = NF_IP6_PRI_FIRST;
In this case no packet is hooked.
2)
netfilter_ops.pf = PF_IEEE802154
I got a crash on loading the module
...
[ 28.608943] [<c047a908>] (nf_register_hook+0x38/0x84) from [<bf0da050>]
