18d474781f Switch to using a struct xucred instead of a struct xucred when not
actually in the kernel.  This structure is a different size than
what is currently in -CURRENT, but should hopefully be the last time
any application breakage is caused there.  As soon as any major
inconveniences are removed, the definition of the in-kernel struct
ucred should be conditionalized upon defined(_KERNEL).

This also changes struct export_args to remove dependency on the
constantly-changing struct ucred, as well as limiting the bounds
of the size fields to the correct size.  This means: a) mountd and
friends won't break all the time, b) mountd and friends won't crash
the kernel all the time if they don't know what they're doing wrt
actual struct export_args layout.

4b6a7bddad * Rename M_WAIT mbuf subsystem flag to M_TRYWAIT.
This is because calls with M_WAIT (now M_TRYWAIT) may not wait
  forever when nothing is available for allocation, and may end up
  returning NULL. Hopefully we now communicate more of the right thing
  to developers and make it very clear that it's necessary to check whether
  calls with M_(TRY)WAIT also resulted in a failed allocation.
  M_TRYWAIT basically means "try harder, block if necessary, but don't
  necessarily wait forever." The time spent blocking is tunable with
  the kern.ipc.mbuf_wait sysctl.
  M_WAIT is now deprecated but still defined for the next little while.

* Fix a typo in a comment in mbuf.h

* Fix some code that was actually passing the mbuf subsystem's M_WAIT to
  malloc(). Made it pass M_WAITOK instead. If we were ever to redefine the
  value of the M_WAIT flag, this could have became a big problem.

954e1d2ccd Lock down the network interface queues. The queue mutex must be obtained
before adding/removing packets from the queue.  Also, the if_obytes and
if_omcasts fields should only be manipulated under protection of the mutex.

IF_ENQUEUE, IF_PREPEND, and IF_DEQUEUE perform all necessary locking on
the queue.  An IF_LOCK macro is provided, as well as the old (mutex-less)
versions of the macros in the form _IF_ENQUEUE, _IF_QFULL, for code which
needs them, but their use is discouraged.

Two new macros are introduced: IF_DRAIN() to drain a queue, and IF_HANDOFF,
which takes care of locking/enqueue, and also statistics updating/start
if necessary.

df0e25bf6c 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".

This is necessary before 4.0, because,
  -This change is non backword compatible
  -Other KAME derived platforms applied 05
  -Author of the draft said he never do backword imcompatible changes
   again.

0539d56f5e Prototype fix for IPsec authentication related functions
Some of IPsec authentication related functions should have
  'const' for its 2nd argument, but not now.
  But if someone try to use them, and passed const data for
  those functions, then much bogus compile warnings will be
  generated.
  So those funcs prototype should be modified.

a0c9aca93b Forbid include of soem inet6 header files from wrong place
KAME put INET6 related stuff into sys/netinet6 dir, but IPv6
  standard API(RFC2553) require following files to be under sys/netinet.
    netinet/ip6.h
    netinet/icmp6.h
  Now those header files just include each following files.
    netinet6/ip6.h
    netinet6/icmp6.h

  Also KAME has netinet6/in6.h for easy INET6 common defs
  sharing between different BSDs, but RFC2553 requires only
  netinet/in.h should be included from userland.
  So netinet/in.h also includes netinet6/in6.h inside.

  To keep apps portability, apps should not directly include
  above files from netinet6 dir.
  Ideally, all contents of,
    netinet6/ip6.h
    netinet6/icmp6.h
    netinet6/in6.h
  should be moved into
    netinet/ip6.h
    netinet/icmp6.h
    netinet/in.h
  but to avoid big changes in this stage, add some hack, that
    -Put some special macro define into those files under neitnet
    -Let files under netinet6 cause error if it is included
     from some apps, and, if the specifal macro define is not
     defined.
     (which should have been defined if files under netinet is
     included)
    -And let them print an error message which tells the
     correct name of the include file to be included.

  Also fix apps which includes invalid header files.

eb70be25c7 IPv6 prefix assignment bug fixes.
(1)When all related IPv6 addresses are removed,
       then remove the associated IPv6 prefix.
    (2)When multiple IPv6 link local addrs exist for a same
       interface , then let its IPv6 prefix have multiple
       interface id, and create multiple IPv6 global addrs with same
       interface id.
    (3)When a new IPv6 link local addr is assigned for an
       interface, then let its IPv6 prefix also have the
       interface id of the new IPv6 link local addr, and
       create new IPv6 global addrs with same interface id.

f70608d097 Permit site local addr in IPv6 source address selection rule.
KAME source addr selection rule had a problem to treat IPv6 site
  local addr.
  The rule is completely rewritten recently and the above problem
  is also fixed, but rewriting same code part in freebsd4.0 is too
  dangerous in this stage, so just add workaround to avoid
  the problem. Just add code for IPv6 site local addresses into IPv6
  source addr selection algorythm part.

2ef83ec04a Added ip6_forwarding check when prefix related ioctl is called.
(prefix related ioctl should only be called on router,
because host use dynamic address and prefix configuration mechanism,
and those prefix are managed separately with ones whih are assined
manually.)

26fcba4c5a Move the *intrq variables into net/intrq.c and unconditionally
include this in all kernels.  Declare some const *intrq_present
variables that can be checked by a module prior to using *intrq
to queue data.

Make the if_tun module capable of processing atm, ip, ip6, ipx,
natm and netatalk packets when TUNSIFHEAD is ioctl()d on.

4338629a91 fix kernel panic at rtfree() in INET6 enabled envrionment.
This is probably due to twice rtfree() in in6_pcbdetach(),
  one for inp->in6p_route.ro_rt, and another one for inp->inp_route.ro_rt.
  But these 2 are actually shared in inpcb, so 2nd rtfree() is not necessary.
