Description

Trying to start-up ggsn on a FreeBSD v11 box with

listen: 1.1.1.1
net 192.168.1.0/24
dynip: 192.168.1.0/24

results in errno 22 from tun.c

This looks to be the code section where it is failing:

 if (addr) { /* Set the interface address */
    this->addr.s_addr = addr->s_addr;
    memcpy(&((struct sockaddr_in *) &ifr.ifr_addr)->sin_addr, addr,
      sizeof(*addr));
    if (ioctl(fd, SIOCSIFADDR, (void *) &ifr) < 0) {
      if (errno != EEXIST) {
    sys_err(LOG_ERR, __FILE__, __LINE__, errno,
        "ioctl(SIOCSIFADDR) failed");
      }
      else {
    sys_err(LOG_WARNING, __FILE__, __LINE__, errno,
        "ioctl(SIOCSIFADDR): Address already exists");
      }
      close(fd);
      return -1;
    }
  }

The server is running

FreeBSD soak01.eng.paloaltonetworks.local 11.0-RELEASE-p2 FreeBSD 11.0-RELEASE-p2 #0: Mon Oct 24 06:55:27 UTC 2016     root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC  amd64
