- prepare for RFC2401bis 64bit sequence number (no behavior change yet) - use hash for SPI-based SAD entry lookup (should be faster, i hope) - cleanup keydb.c and key.c. key.c is responsible for refcounting secasvar, keydb.c is responsible for alloc/free.

sync with almost-latest KAME IPsec. full changelog would be too big to mention here. notable changes are like below. kernel: - make PF_KEY kernel interface more robust against broken input stream. it includes complete internal structure change in sys/netkey/key.c. - remove non-RFC compliant change in PF_KEY API, in particular, in struct sadb_msg. we cannot just change these standard structs. sadb_x_sa2 is introduced instead. - remove prototypes for pfkey_xx functions from /usr/include/net/pfkeyv2.h. these functions are not supplied in /usr/lib. setkey(8): - get/delete does not require "-m mode" (ignored with warning, if you specify it) - spddelete takes direction specification

__P((struct ipsecrequest *isr, struct secasindex *));
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.
