      IPv6: Generic TTL Security Mechanism (final version) · e802af9c
      Stephen Hemminger 提交于
      This patch adds IPv6 support for RFC5082 Generalized TTL Security Mechanism.  
      
      Not to users of mapped address; the IPV6 and IPV4 socket options are seperate.
      The server does have to deal with both IPv4 and IPv6 socket options
      and the client has to handle the different for each family.
      
      On client:
      	int ttl = 255;
      	getaddrinfo(argv[1], argv[2], &hint, &result);
      
      	for (rp = result; rp != NULL; rp = rp->ai_next) {
      		s = socket(rp->ai_family, rp->ai_socktype, rp->ai_protocol);
      		if (s < 0) continue;
      
      		if (rp->ai_family == AF_INET) {
      			setsockopt(s, IPPROTO_IP, IP_TTL, &ttl, sizeof(ttl));
      		} else if (rp->ai_family == AF_INET6) {
      			setsockopt(s, IPPROTO_IPV6,  IPV6_UNICAST_HOPS, 
      					&ttl, sizeof(ttl)))
      		}
      			
      		if (connect(s, rp->ai_addr, rp->ai_addrlen) == 0) {
      		   ...
      
      On server:
      	int minttl = 255 - maxhops;
         
      	getaddrinfo(NULL, port, &hints, &result);
      	for (rp = result; rp != NULL; rp = rp->ai_next) {
      		s = socket(rp->ai_family, rp->ai_socktype, rp->ai_protocol);
      		if (s < 0) continue;
      
      		if (rp->ai_family == AF_INET6)
      			setsockopt(s, IPPROTO_IPV6,  IPV6_MINHOPCOUNT,
      					&minttl, sizeof(minttl));
      		setsockopt(s, IPPROTO_IP, IP_MINTTL, &minttl, sizeof(minttl));
      			
      		if (bind(s, rp->ai_addr, rp->ai_addrlen) == 0)
      			break
