david 0674925f73 Skip over entire ifreq struct in NEXTIFR. ... On platforms supporting sa_len, NEXTIFR would skip over sa_len bytes starting at the beginning of ifr_addr, and assume that was the end of the struct. (The idea being that a large address such as a sockaddr_in6 could overflow the nominal struct boundary.) This logic was wrong when there was something else in the union bigger than sa_len; we would increment into somewhere in the middle of the same struct. This exhibited itself on NetBSD, where struct ifreq has a sockaddr_storage member in its internal union: struct ifreq { char ifr_name[IFNAMSIZ]; /* if name, e.g. "en0" */ union { struct sockaddr ifru_addr; struct sockaddr ifru_dstaddr; struct sockaddr ifru_broadaddr; struct sockaddr_storage ifru_space; No, we skip over sa_len bytes, or to the nominal end of the struct, whichever is larger. Unix Network Programming gets this wrong too; in figure 17.8 they do ptr += sizeof(ifr->ifr_name) + max(sizeof(struct sockaddr), ifr->ifr_addr.sa_len);		2012-09-10 01:17:28 +00:00
