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;
--- net/ipv4/devinet.c.~1~ Thu Jun 10 07:54:44 1999 +++ net/ipv4/devinet.c Fri Jun 11 09:17:34 1999 @@ -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?
