[SOLVED] netnworking

I'm writing a network protocol module, and having trouble getting the information from a connected peer socket. I don't know where to pull this info from and don't understand the kernel examples.

Here is my 'struct proto_ops' callback of .getname.

Code:

static int my_getname(struct socket *sock, struct sockaddr *uaddr,
        int *uaddr_len, int peer)
{
    struct sock *sk = sock->sk;
    struct sockaddr_in *sin = (struct sockaddr_in *)uaddr;

    sin->sin_family = AF_INET;

    *uaddr_len = sizeof(struct sockaddr);

    return 0;
}

I'm just not sure how to populate the 'struct sockaddr' w/ the protocol address.

update ... It comes from the accept().

Hello,

Noticed that you have marked your thread as solved; What was the final fix?

Cheers,

I had edited the original post that this info comes from the accept() method, getname() is called after using that info obtained by accept() on a socket.
