WebOn Linux-based systems, one way to obtain the IPv4 address of an interface is to use the ioctl command SIOCGIFADDR. The method described here has four steps: Create an ifreq structure for passing data in and out of ioctl. Provide an open socket descriptor with the address family AF_INET. Invoke ioctl. Extract the IP address from the ifreq ...

To not break existing tools that pass down the wrong struct we will do the same as for RTM_GETLINK NLM_F_DUMP requests and not error out when the nlmsg_parse() fails. - Security: Callers must have CAP_NET_ADMIN in the owning user namespace of the target network namespace.
