* Pull post-4.4BSD change to sys/net/route.c from BSD/OS 4.2.ru2001-10-171-0/+5
| | | | | | | | | | | | | | | | | | | | Have sys/net/route.c:rtrequest1(), which takes ``rt_addrinfo *'' as the argument. Pass rt_addrinfo all the way down to rtrequest1 and ifa->ifa_rtrequest. 3rd argument of ifa->ifa_rtrequest is now ``rt_addrinfo *'' instead of ``sockaddr *'' (almost noone is using it anyways). Benefit: the following command now works. Previously we needed two route(8) invocations, "add" then "change". # route add -inet6 default ::1 -ifp gif0 Remove unsafe typecast in rtrequest(), from ``rtentry *'' to ``sockaddr *''. It was introduced by 4.3BSD-Reno and never corrected. Obtained from: BSD/OS, NetBSD MFC after: 1 month PR: kern/28360

* Add three new route flags to help determine what sort of addresswollman1996-05-061-2/+5
| | | | | | | | | | | | | | | | | | | | | | the destination represents. For IP: - Iff it is a host route, RTF_LOCAL and RTF_BROADCAST indicate local (belongs to this host) and broadcast addresses, respectively. - For all routes, RTF_MULTICAST is set if the destination is multicast. The RTF_BROADCAST flag is used by ip_output() to eliminate a call to in_broadcast() in a common case; this gives about 1% in our packet-generation experiments. All three flags might be used (although they aren't now) to determine whether a packet can be forwarded; a given host route can represent a forwardable address if: (rt->rt_flags & (RTF_HOST | RTF_LOCAL | RTF_BROADCAST | RTF_MULTICAST)) == RTF_HOST Obviously, one still has to do all the work if a host route is not present, but this code allows one to cache the results of such a lookup if rtalloc1() is called without masking RTF_PRCLONING.

This will be yet another incompatible change in your route-using binaries. I apologize, but this was the only way to do it.

Also add another parameter to rtalloc1() to allow for any interface flags to be ignored; currently this is only useful for RTF_PRCLONING. Get rid of rt_prflags and re-unite with rt_flags. Add T/TCP ``route metrics''. NB: YOU MUST RECOMPILE `route' AND OTHER RELATED PROGRAMS AS A RESULT OF THIS CHANGE. This also adds a new interface parameter, `ifi_physical', which will eventually replace IFF_ALTPHYS as the mechanism for specifying the particular physical connection desired on a multiple-connection card. NB: YOU MUST RECOMPILE `ifconfig' AND OTHER RELATED PROGRAMS AS A RESULT OF THIS CHANGE.
