To be a little more informative. Yes I could use the ipfw and make a divert rule to go to my userland app, but I am being more specific in what I want sent to my listening userland app. So what is the proper way, when I am in the send function of my Socket level nke, to divert the packet to my userland apps listening port. Currently I am closing that socket and opening a new one and connecting it to my userland app. Like I mentioned in the previous post. int vi_send2(struct socket *so, struct sockaddr_in **addr, struct uio **uio, struct mbuf **top, struct mbuf **control, int *flags, register struct kextcb *kp) { int funnel_state; funnel_state = thread_funnel_set(network_flock, TRUE); //Code to figure out if get, already done if(GETREQUEST) { // Need to Divert packet now to my userland app, below is what I try to do: struct sockaddr_in server; /* the information structure for the server (to be filled out) */ bzero(&server, sizeof(struct sockaddr_in)); struct in_addr s_addr; s_addr.s_addr = 2130706433; server.sin_len = sizeof(server); memcpy(&server.sin_addr, &s_addr, sizeof(struct in_addr)); server.sin_family = AF_INET; // Set the server's family server.sin_port = htons((unsigned short) 48080); /* Set the port to connect to... */ int threeerror = sodisconnect(so); printf("threeerror: %d\n", threeerror); int shuterror = soshutdown(so,2); printf("shuterror: %d\n", shuterror); //int mosterror = soclose(so); //printf("mosterror: %d\n", mosterror); int testerror = socreate(AF_INET, &so,SOCK_STREAM,0); printf("testerror: %d\n", testerror); int theerrors = soconnect(so, (struct sockaddr*)&server); printf("theerrors: %d\n", theerrors); } } On Jun 7, 2004, at 1:21 AM, Matt Jaffa wrote:
Hi,
I have successfully created a NKE and I am particularily interested in
the send function that I am using.
In the send function I detect if the outgoing message is a GET request
if so I do this:
if( is a GET request) {
struct sockaddr_in server; /* the information structure for the server
(to be filled out) */
bzero(&server, sizeof(struct sockaddr_in));
struct in_addr s_addr;
s_addr.s_addr = 2130706433;
server.sin_len = sizeof(server);
memcpy(&server.sin_addr, &s_addr, sizeof(struct in_addr));
server.sin_family = AF_INET; // Set the server's family
server.sin_port = htons((unsigned short) 48080); /* Set the port to
connect to... */
int threeerror = sodisconnect(so);
printf("threeerror: %d\n", threeerror);
int shuterror = soshutdown(so,2);
printf("shuterror: %d\n", shuterror);
//int mosterror = soclose(so);
//printf("mosterror: %d\n", mosterror);
int testerror = socreate(AF_INET, &so,SOCK_STREAM,0);
printf("testerror: %d\n", testerror);
int theerrors = soconnect(so, (struct sockaddr*)&server);
printf("theerrors: %d\n", theerrors);
}
And then I have a daemon that is listening on 127.0.0.1 with port
48080. In the daemon it successfully gets past the accept, but spins
on recv(....,...,....,....) forever. So I am assuming that in the
Kernel after I have redirected the socket to my daemon, and then when
the send function returns it sends that GET request instead to my
daemon, where I can look at the information.
But in my daemon the accept works, but it doesn't get past
recv(,,,,,,,,,);
What to do?
thanks,
Matt
