Hello! In a kernel module of mine I have a struct socket available and need to get a struct sockaddr_in or something equivalent from it. The goal is to get IP address and port for sockets of family AF_INET or AF_INET6. I have tried the following (sock is a struct socket): struct sockaddr addr; int len = sizeof(struct sockaddr); sock->ops->getname(sock, &addr, &len, 2); Every call of getname returns the error code -107. The socket structure represents a BSD socket. It has a field pointing to an INET socket (struct sock *sk). That is an internal networking protocol agnostic socket representation. Therefore, there are no fields for IP addresses and ports as this is protocol dependent. Do you have any advice on how to get the needed information?
