Hi, All
I create a virtual netowrk card by supplementing a network driver. To simulate the activity of receving packets I customize packet data and call ioctl to feed them to netif_rx. My registered hook is like this
static struct nf_hook_ops ns_hook = { {NULL,NULL},scan_hook,
//PF_INET,NF_IP_PRE_ROUTING, //I have tried this
PF_BRIDGE,NF_BR_PRE_ROUTING, // and this
1};
Both hooks point does not work for my crafted data but work for real packets (through real NIC).
Does anyone know what I'm doing wrong? Thanks for help.
Derek
