Raw Normal View History

KNF: de-__P, bzero -> memset, bcmp -> memcmp. Remove extraneous parentheses in return statements. Cosmetic: don't open-code TAILQ_FOREACH(). Cosmetic: change types of variables to avoid oodles of casts: in in6_src.c, avoid casts by changing several route_in6 pointers to struct route pointers. Remove unnecessary casts to caddr_t elsewhere. Pave the way for eliminating address family-specific route caches: soon, struct route will not embed a sockaddr, but it will hold a reference to an external sockaddr, instead. We will set the destination sockaddr using rtcache_setdst(). (I created a stub for it, but it isn't used anywhere, yet.) rtcache_free() will free the sockaddr. I have extracted from rtcache_free() a helper subroutine, rtcache_clear(). rtcache_clear() will "forget" a cached route, but it will not forget the destination by releasing the sockaddr. I use rtcache_clear() instead of rtcache_free() in rtcache_update(), because rtcache_update() is not supposed to forget the destination. Constify: 1 Introduce const accessor for route->ro_dst, rtcache_getdst(). 2 Constify the 'dst' argument to ifnet->if_output(). This led me to constify a lot of code called by output routines. 3 Constify the sockaddr argument to protosw->pr_ctlinput. This led me to constify a lot of code called by ctlinput routines. 4 Introduce const macros for converting from a generic sockaddr to family-specific sockaddrs, e.g., sockaddr_in: satocsin6, satocsin, et cetera.

sync gif interface code with latest kame. IFF_RUNNING is clearified. attach/detach logic is more clearner. the old code mistakenly set IFF_UP by itself, now the behavior is gone.

introduce sys/netinet/ip_encap.c, to dispatch inbound packets to protocol handlers, based on src/dst (for ip proto #4/41). see comment in ip_encap.c for details of the problem we have. there are too many protocol specs for ip proto #4/41. backward compatibility with MROUTING case is now provided in ip_encap.c. fix ipip to work with gif (using ip_encap.c). sorry for breakage. gif now uses ip_encap.c. introduce stf pseudo interface (implements 6to4, another IPv6-over-IPv4 code with ip proto #41).
