This is basically what I have in my program:
int socketfd = 0;
struct ifreq ifr;
static const char *wpandevs[] = {
"wpan0"
};
socket_config_wpan = wpandevs[0];
socketfd = socket(PF_IEEE802154, SOCK_RAW, 0);
strncpy(ifr.ifr_name, socket_config_wpan, IF_NAMESIZE);
ret = ioctl(socketfd, SIOCGIFADDR, &ifr);
if (ret < 0) {
fprintf(stderr,"ioctl: SIOCGIFADDR error\n");
return;
}
In can say that in kernel 3.8.13 it works with no problems.

mhh, this sounds like another issue.
1. What's your exactly ioctl call, then I can maybe reproduce your issue.
2. There are some information missing at you stacktrace, can you provide
more information?
