232bdaf61f printed current sequence number of the SA. accordingly, changed
into sadb_x_sa2_sequence from sadb_x_sa2_reserved3 in the sadb_x_sa2
structure.  Also the output of setkey is changed.  sequence number
of the sadb is replaced to the end of the output.

3384154590 Sync with recent KAME.
This work was based on kame-20010528-freebsd43-snap.tgz and some
critical problem after the snap was out were fixed.
There are many many changes since last KAME merge.

TODO:
  - The definitions of SADB_* in sys/net/pfkeyv2.h are still different
    from RFC2407/IANA assignment because of binary compatibility
    issue.  It should be fixed under 5-CURRENT.
  - ip6po_m member of struct ip6_pktopts is no longer used.  But, it
    is still there because of binary compatibility issue.  It should
    be removed under 5-CURRENT.

a5c4836d39 Replace the mbuf external reference counting code with something
that should be better.

The old code counted references to mbuf clusters by using the offset
of the cluster from the start of memory allocated for mbufs and
clusters as an index into an array of chars, which did the reference
counting. If the external storage was not a cluster then reference
counting had to be done by the code using that external storage.

NetBSD's system of linked lists of mbufs was cosidered, but Alfred
felt it would have locking issues when the kernel was made more
SMP friendly.

The system implimented uses a pool of unions to track external
storage. The union contains an int for counting the references and
a pointer for forming a free list. The reference counts are
incremented and decremented atomically and so should be SMP friendly.
This system can track reference counts for any sort of external
storage.

Access to the reference counting stuff is now through macros defined
in mbuf.h, so it should be easier to make changes to the system in
the future.

The possibility of storing the reference count in one of the
referencing mbufs was considered, but was rejected 'cos it would
often leave extra mbufs allocated. Storing the reference count in
the cluster was also considered, but because the external storage
may not be a cluster this isn't an option.

The size of the pool of reference counters is available in the
stats provided by "netstat -m".

686cdd19b1 sync with kame tree as of july00. tons of bug fixes/improvements.
API changes:
- additional IPv6 ioctls
- IPsec PF_KEY API was changed, it is mandatory to upgrade setkey(8).
  (also syntax change)

5d60ed0e69 Change struct sockaddr_storage member name, because following change
is very likely to become consensus as recent ietf/ipng mailing list
discussion. Also recent KAME repository and other KAME patched BSDs
also applied it.

  s/__ss_family/ss_family/
  s/__ss_len/ss_len/

Makeworld is confirmed, and no application should be affected by this change
yet.

664a31e496 Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot).  This is consistant with the other
BSD's who made this change quite some time ago.  More commits to come.

751bf650a8 make sys/netkey/key{,_debug}.c compile. I believe it works but not tested.
I'll polish the code later on.

bd22f58e11 This is the `netkey' kernel key-management service (the PF_KEY analogue
to PF_ROUTE) from NRL's IPv6 distribution, heavily modified by me for
better source layout, formatting, and textual conventions.  I am told
that this code is no longer under active development, but it's a useful
hack for those interested in doing work on network security, key management,
etc.  This code has only been tested twice, so it should be considered
highly experimental.
