It is turned off by default. MFC r242082: Note the removal of the IPFIREWALL_FORWARD kernel option. MFC r242463: Remove the recently added sysctl variable net.pfil.forward. Instead, add protocol specific mbuf flags M_IP_NEXTHOP and M_IP6_NEXTHOP. Use them to indicate that the mbuf's chain contains the PACKET_TAG_IPFORWARD tag. And do a tag lookup only when this flag is set. 2012-09-10T11:38:02Z Gleb Smirnoff glebius@FreeBSD.org 2012-09-10T11:38:02Z urn:sha1:3d372672012f2485881efb21ab5916b770a34a22 r238002 by tuexen@: Remove dead code (on FreeBSD) as suggested by glebius@. r238016: Remove route caching from IP multicast routing code. There is no reason to do that, and also, cached route never got unreferenced, which meant a reference leak. Reviewed by: bms r238092: When ip_output()/ip6_output() is supplied a struct route *ro argument, it skips FLOWTABLE lookup. However, the non-NULL ro has dual meaning here: it may be supplied to provide route, and it may be supplied to store and return to caller the route that ip_output()/ip6_output() finds. In the latter case skipping FLOWTABLE lookup is pessimisation. The difference between struct route filled by FLOWTABLE and filled by rtalloc() family is that the former doesn't hold a reference on its rtentry. Reference is hold by flow entry, and it is about to be released in future. Thus, route filled by FLOWTABLE shouldn't be passed to RTFREE() macro. - Introduce new flag for struct route/route_in6, that marks route not holding a reference on rtentry. - Introduce new macro RO_RTFREE() that cleans up a struct route depending on its kind. - All callers to ip_output()/ip6_output() that do supply non-NULL but empty route should use RO_RTFREE() to free results of lookup. - ip_output()/ip6_output() now do FLOWTABLE lookup always when ro->ro_rt == NULL. 2012-07-01T08:47:15Z Michael Tuexen tuexen@FreeBSD.org 2012-07-01T08:47:15Z urn:sha1:063d7f5ea4e0405528f7981afcab27a1d7df9522 Add a IP_RECVTOS socket option to receive for received UDP/IPv4 packets a cmsg of type IP_RECVTOS which contains the TOS byte. Much like IP_RECVTTL does for TTL. This allows to implement a protocol on top of UDP and implementing ECN. 2012-03-19T20:49:16Z John Baldwin jhb@FreeBSD.org 2012-03-19T20:49:16Z urn:sha1:391465f779db8f6d6ac9045a93c6ba1bb6e6aeab Convert all users of IF_ADDR_LOCK to use new locking macros that specify either a read lock or write lock. 2011-10-20T15:58:05Z Gleb Smirnoff glebius@FreeBSD.org 2011-10-20T15:58:05Z urn:sha1:f0ce48d9d5f1954fb5aa801fb52b5e27613f0772 Remove last remnants of classful addressing: - Remove ia_net, ia_netmask, ia_netbroadcast from struct in_ifaddr. - Remove net.inet.ip.subnetsarelocal, I bet no one need it in 2011. - fix bug when we were not forwarding to a host which matches classful net address. For example router having 192.168.x.y/16 network attached, would not forward traffic to 192.168.*.0, which are legal IPs in CIDR world. - For compatibility, leave autoguessing of mask based on class. Reviewed by: andre, bz, rwatson Add support for IPv4 /31 prefixes, as described in RFC3021. To run a /31 network, participating hosts MUST drop support for directed broadcasts, and treat the first and last addresses on subnet as unicast. The broadcast address for the prefix should be the link local broadcast address, INADDR_BROADCAST. Approved by: re (kib) 2011-06-08T03:02:11Z Bjoern A.

In an IPv6 only world we do not want to compile ip_input.c in for that and it is a shared default with INET6.

The random source port allocation code has been merged and is now local to in_pcb.c only. Use a SYSINIT to get the callout started and no longer depend on initialization from the inet code, which would not work in an IPv6 only setup.
