The following code returns EFAULT (Bad address): s = socket(AF_INET6, SOCK_RAW, IPPROTO_ICMPV6); setsockopt(s, SOL_IPV6, IPV6_HDRINCL, 1); sendto(ipv6_icmp6_packet, addr); /* returns -1, errno = EFAULT */
The problem is fixed in the second patch. The first one aligns the code to ipv4, to avoid a race condition in the second patch.
