Send packet with sockets from kernel module -

i writing kernel module should receive messages user-space , send response via socket.

when program , module on same machine , use ip 127.0.0.1, works fine. when try on different machines , use real network ip, 192.168.3.146 works in 1 way.

i receive message user-space, can not receive kernel. use sock_sendmsg function sending message kernel , it's not return error. not messages firewall came machine, kernel module.

here similar questions , examples, not useful enough me or examples used old kernel version.for skeleton used one,from udp sockets: http://people.ee.ethz.ch/~arkeller/linux/multi/kernel_user_space_howto-3.html. help?

kernel module code sending:

void send_data(unsigned char *data) {     if(!is_err_or_null(data))     {         int ret;         mm_segment_t oldfs;         struct msghdr message;         struct iovec iovector;         struct sockaddr_in sendaddr;          sendaddr.sin_family = af_inet;         sendaddr.sin_addr.s_addr = inaddr_any;         //sendaddr.sin_addr.s_addr = in_aton("192.168.1.75");         //here port sk_buff structure received.         sendaddr.sin_port = *((unsigned short*)skbuffer->data);          memset(&message, 0, sizeof(message));         message.msg_name = &sendaddr;         message.msg_namelen = sizeof(sendaddr);          /* send message */         iovector.iov_base = data;         iovector.iov_len  = strlen(data);         message.msg_iov = &iovector;         message.msg_iovlen = 1;         message.msg_control = null;         message.msg_controllen = 0;          oldfs = get_fs();         set_fs(kernel_ds);         ret = sock_sendmsg(sendsocket, &message, strlen(data));         set_fs(oldfs);     } } 

i found alternative solution, using netpoll sockets. more easier sockets, used before , works. answer , proper code here, on stackoverflow question.
