    Here's a patch. The problem is the following change in
    net/ipv4/devinet (early 2.3.x):
    - struct ifreq ifr;
    + struct ifreq *ifr = (struct ifreq *) buf;

    @@ -615,10 +615,10 @@

    for ( ; ifa; ifa = ifa->ifa_next) {
    if (!ifr) {
    - done += sizeof(ifr);
    + done += sizeof(struct ifreq);
    continue;
    }
    - if (len < (int) sizeof(ifr))
    + if (len < (int) sizeof(struct ifreq))
    return done;
    memset(ifr, 0, sizeof(struct ifreq));
    if (ifa->ifa_label)
    Could this please added to Linux 2.3.15?

    Thanks,
    Andreas
