Raw socket in Linux Kernel - sockets

Question

I have an issue with this code:
bool send_packet(uint8_t *frame, const uint32_t size)
{
int len, ret;
struct iphdr *ip;
struct msghdr msg;
struct kvec vec;
ip = (struct iphdr*)(frame + ETH_HLEN); // Align ip header with buffer
tgb_pr_debug("packet ip version : %d\n",ip->version);
tgb_pr_debug("packet from %pI4 to %pI4\n",&ip->saddr, &ip->daddr);
tgb_pr_debug("packet ip protocol : %d\n",ip->protocol);
memset(&msg,0,sizeof(msg));
len = size - ETH_HLEN;
vec.iov_base = ip;
vec.iov_len = len;
ret = kernel_sendmsg(sock,&msg,&vec,1,len);
if (ret < 0) {
pr_err("sendmsg return code %d\n",ret);
return false;
}
kfree(frame);
return true;
}
With high rate it's freeze the computer. Is socket right way to send packet in Linux Kernel?

Answer 1

With this implémention i have no issue, it's work perfectly, if someone know why i'm interested
struct sk_buff* skb, *trailer;
struct net_device *dev;
dev = dev_get_by_name(&init_net,"enp0s5");
skb = alloc_skb(size+ETH_HLEN+2,GFP_ATOMIC);
memcpy(skb_put(skb, size), frame, size);
kfree(frame); //free buffer get from ipseclib
skb_reset_network_header(skb);
skb->dev = dev;
skb->pkt_type = PACKET_OUTGOING;
skb_cow_data(skb,1,&trailer);
dev_queue_xmit(skb);
