From: Guus Sliepen Date: Fri, 15 Apr 2016 14:56:56 +0000 (+0200) Subject: Stop using SOL_TCP, SOL_IP and SOL_IPV6. X-Git-Tag: release-1.1pre12~21 X-Git-Url: https://git.tinc-vpn.org/git/browse?a=commitdiff_plain;h=a31e1f03c4eff16403178695d971a0838996ba2e;p=tinc Stop using SOL_TCP, SOL_IP and SOL_IPV6. Instead, use IPPROTO_TCP, _IP and _IPv6. This fixes an issue on OS X where it didn't create an UDP socket that listened on IPv4. --- diff --git a/src/net_packet.c b/src/net_packet.c index 7d61e7b2..345175ea 100644 --- a/src/net_packet.c +++ b/src/net_packet.c @@ -719,10 +719,10 @@ static void send_udppacket(node_t *n, vpn_packet_t *origpkt) { if(priorityinheritance && origpriority != listen_socket[sock].priority) { listen_socket[sock].priority = origpriority; switch(sa->sa.sa_family) { -#if defined(SOL_IP) && defined(IP_TOS) +#if defined(IPPROTO_IP) && defined(IP_TOS) case AF_INET: logger(DEBUG_TRAFFIC, LOG_DEBUG, "Setting IPv4 outgoing packet priority to %d", origpriority); - if(setsockopt(listen_socket[sock].udp.fd, SOL_IP, IP_TOS, &origpriority, sizeof origpriority)) /* SO_PRIORITY doesn't seem to work */ + if(setsockopt(listen_socket[sock].udp.fd, IPPROTO_IP, IP_TOS, &origpriority, sizeof origpriority)) /* SO_PRIORITY doesn't seem to work */ logger(DEBUG_ALWAYS, LOG_ERR, "System call `%s' failed: %s", "setsockopt", sockstrerror(sockerrno)); break; #endif diff --git a/src/net_setup.c b/src/net_setup.c index 0c074719..cbd3954c 100644 --- a/src/net_setup.c +++ b/src/net_setup.c @@ -591,7 +591,7 @@ bool setup_myself_reloadable(void) { subnet_add(NULL, s); } -#if !defined(SOL_IP) || !defined(IP_TOS) +#if !defined(IPPROTO_IP) || !defined(IP_TOS) if(priorityinheritance) logger(DEBUG_ALWAYS, LOG_WARNING, "%s not supported on this platform for IPv4 connections", "PriorityInheritance"); #endif diff --git a/src/net_socket.c b/src/net_socket.c index 8983d289..bafea64d 100644 --- a/src/net_socket.c +++ b/src/net_socket.c @@ -35,11 +35,6 @@ #include "utils.h" #include "xalloc.h" -/* Needed on Mac OS/X */ -#ifndef SOL_TCP -#define SOL_TCP IPPROTO_TCP -#endif - int addressfamily = AF_UNSPEC; int maxtimeout = 900; int seconds_till_retry = 5; @@ -73,14 +68,14 @@ static void configure_tcp(connection_t *c) { } #endif -#if defined(SOL_TCP) && defined(TCP_NODELAY) +#if defined(IPPROTO_TCP) && defined(TCP_NODELAY) option = 1; - setsockopt(c->socket, SOL_TCP, TCP_NODELAY, (void *)&option, sizeof option); + setsockopt(c->socket, IPPROTO_TCP, TCP_NODELAY, (void *)&option, sizeof option); #endif -#if defined(SOL_IP) && defined(IP_TOS) && defined(IPTOS_LOWDELAY) +#if defined(IPPROTO_IP) && defined(IP_TOS) && defined(IPTOS_LOWDELAY) option = IPTOS_LOWDELAY; - setsockopt(c->socket, SOL_IP, IP_TOS, (void *)&option, sizeof option); + setsockopt(c->socket, IPPROTO_IP, IP_TOS, (void *)&option, sizeof option); #endif #if defined(IPPROTO_IPV6) && defined(IPV6_TCLASS) && defined(IPTOS_LOWDELAY) @@ -168,9 +163,9 @@ int setup_listen_socket(const sockaddr_t *sa) { option = 1; setsockopt(nfd, SOL_SOCKET, SO_REUSEADDR, (void *)&option, sizeof option); -#if defined(SOL_IPV6) && defined(IPV6_V6ONLY) +#if defined(IPPROTO_IPV6) && defined(IPV6_V6ONLY) if(sa->sa.sa_family == AF_INET6) - setsockopt(nfd, SOL_IPV6, IPV6_V6ONLY, (void *)&option, sizeof option); + setsockopt(nfd, IPPROTO_IPV6, IPV6_V6ONLY, (void *)&option, sizeof option); #endif if(get_config_string @@ -266,10 +261,10 @@ int setup_vpn_in_socket(const sockaddr_t *sa) { #define IP_DONTFRAGMENT IP_DONTFRAG #endif -#if defined(SOL_IP) && defined(IP_MTU_DISCOVER) && defined(IP_PMTUDISC_DO) +#if defined(IPPROTO_IP) && defined(IP_MTU_DISCOVER) && defined(IP_PMTUDISC_DO) if(myself->options & OPTION_PMTU_DISCOVERY) { option = IP_PMTUDISC_DO; - setsockopt(nfd, SOL_IP, IP_MTU_DISCOVER, (void *)&option, sizeof(option)); + setsockopt(nfd, IPPROTO_IP, IP_MTU_DISCOVER, (void *)&option, sizeof(option)); } #elif defined(IPPROTO_IP) && defined(IP_DONTFRAGMENT) if(myself->options & OPTION_PMTU_DISCOVERY) { @@ -278,10 +273,10 @@ int setup_vpn_in_socket(const sockaddr_t *sa) { } #endif -#if defined(SOL_IPV6) && defined(IPV6_MTU_DISCOVER) && defined(IPV6_PMTUDISC_DO) +#if defined(IPPROTO_IPV6) && defined(IPV6_MTU_DISCOVER) && defined(IPV6_PMTUDISC_DO) if(myself->options & OPTION_PMTU_DISCOVERY) { option = IPV6_PMTUDISC_DO; - setsockopt(nfd, SOL_IPV6, IPV6_MTU_DISCOVER, (void *)&option, sizeof(option)); + setsockopt(nfd, IPPROTO_IPV6, IPV6_MTU_DISCOVER, (void *)&option, sizeof(option)); } #elif defined(IPPROTO_IPV6) && defined(IPV6_DONTFRAG) if(myself->options & OPTION_PMTU_DISCOVERY) { @@ -522,10 +517,10 @@ begin: #endif if(proxytype != PROXY_EXEC) { -#if defined(SOL_IPV6) && defined(IPV6_V6ONLY) +#if defined(IPPROTO_IPV6) && defined(IPV6_V6ONLY) int option = 1; if(c->address.sa.sa_family == AF_INET6) - setsockopt(c->socket, SOL_IPV6, IPV6_V6ONLY, (void *)&option, sizeof option); + setsockopt(c->socket, IPPROTO_IPV6, IPV6_V6ONLY, (void *)&option, sizeof option); #endif bind_to_interface(c->socket);
