From d1e2faa40e17fe8f3db591021994d2f5e8b11335 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Wed, 28 Sep 2011 14:23:35 +0400 Subject: IPv6 transport class suppport IPv6 supports the same concept of differentiated service for routing protocols as IPv4, but like too many things, the standards committee decided that having two names for the same thing wasn't good enough and introduced a third more generic term transport class. The socket option to set transport class works the same as IPv4, but the arguments are different. * lib/sockopt.[ch] * setsockopt_ipv6_tclass(): new function * bgpd/bgp_network.c * bgp_connect(): set socket option * bgp_listener(): set socket option * ospf6d/ospf6_network.c * ospf6_set_transport_class(): new function * ospf6_serv_sock(): set socket option * ripngd/ripngd.c * ripng_make_socket(): set socket option --- lib/sockopt.c | 13 ++++++++++++- lib/sockopt.h | 1 + 2 files changed, 13 insertions(+), 1 deletion(-) (limited to 'lib') diff --git a/lib/sockopt.c b/lib/sockopt.c index 9ff15ca6..63858408 100644 --- a/lib/sockopt.c +++ b/lib/sockopt.c @@ -179,8 +179,19 @@ getsockopt_ipv6_ifindex (struct msghdr *msgh) return pktinfo->ipi6_ifindex; } -#endif /* HAVE_IPV6 */ +int +setsockopt_ipv6_tclass(int sock, int tclass) +{ + int ret; + + ret = setsockopt (sock, IPPROTO_IPV6, IPV6_TCLASS, &tclass, sizeof (tclass)); + if (ret < 0) + zlog_warn ("Can't set IPV6_TCLASS option for fd %d to %#x: %s", + sock, tclass, safe_strerror(errno)); + return ret; +} +#endif /* HAVE_IPV6 */ /* * Process multicast socket options for IPv4 in an OS-dependent manner. diff --git a/lib/sockopt.h b/lib/sockopt.h index 69309e00..aced6d48 100644 --- a/lib/sockopt.h +++ b/lib/sockopt.h @@ -35,6 +35,7 @@ extern int setsockopt_ipv6_multicast_hops (int, int); extern int setsockopt_ipv6_unicast_hops (int, int); extern int setsockopt_ipv6_hoplimit (int, int); extern int setsockopt_ipv6_multicast_loop (int, int); +extern int setsockopt_ipv6_tclass (int, int); #endif /* HAVE_IPV6 */ /* -- cgit v1.2.1
