Hi, Can you provide an example how to invoke ioctl on device in kernel module. For example. I want to find out the IP address of my eth0 and I want to make SIOCSIFADDR on it from kernel module. At user space i am doing it like this..... unsigned long *ip; char *iface; int sockfd; struct ifreq ifr; strcpy(ifr.ifr_name, iface); // interface name 'eth0' sockfd = socket(AF_INET,SOCK_DGRAM,0); ioctl(sockfd, SIOCGIFADDR, (char*)&ifr); memcpy(ip, &(ifr.ifr_addr.sa_data[2]),4); //Copy the ip addr close(sockfd); How to port this in keernel space. Thank you.
