the mbuf allocator flags {M_TRYWAIT, M_DONTWAIT}.
o Fix a bpf_compat issue where malloc() was defined to just call
bpf_alloc() and pass the 'canwait' flag(s) along. It's been changed
to call bpf_alloc() but pass the corresponding M_TRYWAIT or M_DONTWAIT
flag (and only one of those two).

- set IFF_UP on SIOCSIFADDR. be consistent with others.
- set if_addrlen explicitly (just in case)
- multi destination mode is long gone.
- missing break statement
- add gif_set_tunnel(), so that we can set tunnel address from within the
kernel at ease.
- encap_attach/detach dynamically on ioctls
- move encap_attach() to dedicated function in in*_gif.c

configuration stuff as well as conditional code in the IPv4 and IPv6
areas. Everything is conditional on FAST_IPSEC which is mutually
exclusive with IPSEC (KAME IPsec implmentation).
As noted previously, don't use FAST_IPSEC with INET6 at the moment.

o instead of a list of mbufs use a list of m_tag structures a la openbsd
o for netgraph et. al. extend the stock openbsd m_tag to include a 32-bit
ABI/module number cookie
o for openbsd compatibility define a well-known cookie MTAG_ABI_COMPAT and
use this in defining openbsd-compatible m_tag_find and m_tag_get routines
o rewrite KAME use of aux mbufs in terms of packet tags
o eliminate the most heavily used aux mbufs by adding an additional struct
inpcb parameter to ip_output and ip6_output to allow the IPsec code to
locate the security policy to apply to outbound packets
o bump __FreeBSD_version so code can be conditionalized
o fixup ipfilter's call to ip_output based on __FreeBSD_version

firewall logging on and off when at elevated securelevel(8). It would
be nice to be able to only lock these at securelevel >= 3, like rules
are, but there is no such functionality at present. I don't see reason
to be adding features to securelevel(8) with MAC being merged into 5.0.

o <machine/ansi.h> will continue to live so it can define MD clock
macros, which are only MD because of gratuitous differences between

o Change all headers to make use of this. This mainly involves
changing:

typedef _BSD_FOO_T_ foo_t;
#undef _BSD_FOO_T_

#ifndef _FOO_T_DECLARED

in6_v4mapsin6_sockaddr() which allocate the appropriate sockaddr_in*
structure and initialize it with the address and port information passed
as arguments. Use calls to these new functions to replace code that is
replicated multiple times in in_setsockaddr(), in_setpeeraddr(),
in6_setsockaddr(), in6_setpeeraddr(), in6_mapped_sockaddr(), and
in6_mapped_peeraddr(). Inline COMMON_END in tcp_usr_accept() so that
we can call in_sockaddr() with temporary copies of the address and port
after the PCB is unlocked.
Fix the lock violation in tcp6_usr_accept() (caused by calling MALLOC()
inside in6_mapped_peeraddr() while the PCB is locked) by changing
the implementation of tcp6_usr_accept() to match tcp_usr_accept().

o Use POSIX spelling for types, where possible.
o Define size_t in the __BSD_VISIBLE case (this isn't really needed
for standards conformance, but follows the tradition of not
requiring <sys/types.h> as a prerequisite).
o Use _BYTE_ORDER and friends instead of BYTE_ORDER and friends, since
there may not be enough pollution in order for the latter to work.
o Add an XXX note about the missing IPPROTO_IPV6 macro.
o Add a mutex (sb_mtx) to struct sockbuf. This protects the data in a
socket buffer. The mutex in the receive buffer also protects the data
in struct socket.
o Determine the lock strategy for each members in struct socket.
o Lock down the following members:
- so_count
- so_options
- so_linger
- so_state
o Remove *_locked() socket APIs. Make the following socket APIs
touching the members above now require a locked socket:
- sodisconnect()
- soisconnected()
- soisconnecting()
- soisdisconnected()
- soisdisconnecting()
- sofree()
- soref()
- sorele()
- sorwakeup()

Since locking sigio_lock is usually followed by calling pgsigio(),
move the declaration of sigio_lock and the definitions of SIGIO_*() to
sys/signalvar.h.
While I am here, sort include files alphabetically, where possible.
most cases NULL is passed, but in some cases such as network driver locks
(which use the MTX_NETWORK_LOCK macro) and UMA zone locks, a name is used.

general cleanup of the API. The entire API now consists of two functions
similar to the pre-KSE API. The suser() function takes a thread pointer
as its only argument. The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0. The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.
