Luigi Rizzo 830cc17841 Two main changes here:
+ implement "limit" rules, which permit to limit the number of sessions
   between certain host pairs (according to masks). These are a special
   type of stateful rules, which might be of interest in some cases.
   See the ipfw manpage for details.

 + merge the list pointers and ipfw rule descriptors in the kernel, so
   the code is smaller, faster and more readable. This patch basically
   consists in replacing "foo->rule->bar" with "rule->bar" all over
   the place.
   I have been willing to do this for ages!

Brooks Davis abb6470625 Make stf a clonable device.
Yes this really is rather silly and the implementation is overkill given
that you are only allowed one of them, but NetBSD implements cloning on
this device and it's a less cluttered example of cloning then most.

Julian Elischer b40ce4165d KSE Milestone 2
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

Bill Fenner 02e3112ae7 Don't terminate the uiomove() loop on a zero-length mbuf. It's not
particularly nice that IPSEC inserts a zero-length mbuf into the
 chain, and that bug should be fixed too, but interfaces should be
 robust to bad input.

Hajimu UMEMOTO 9a70151652 As commented in defined in sys/net/route.c, rt_fixchange() has a bad
effect, which would cause unnecessary route deletion:

 * Unfortunately, this has the obnoxious
 * property of also triggering for insertion /above/ a pre-existing network
 * route and clones.  Sigh.  This may be fixed some day.

The effect has been even worse, because recent versions of route.c set
the parent rtentry for cloned routes from an interface-direct route.
For example, suppose that we have an interface "ne0" that has an IPv4
subnet "10.0.0.0/24".  Then we may have a cloned route like 10.0.0.1
on the interface, whose parent route is 10.0.0.0/24 (to the interface
ne0).  Now, when we add the default route (i.e. 0.0.0.0/0),
rt_fixchange() will remove the cloned route 10.0.0.1.  The (bad) effect
also prevents rt_setgate from configuring rt_gwroute, which would not
be an intended behavior.

As suggested in the comments to rt_fixchange(), we need stricter check
in the function, to prevent unintentional route deletion.

This fix also solve the "IPV6 panic?" problem in nd6_timer().

vlan_unconfig()-ing an interface on which multicast groups have been

changing of the membership list) and re-join them when the vlan interface
is reassociated with a lower level interface.

Brian Somers a48de39daf Close a race where we were releasing the unit resource at the start
of tunclose() rather than the end, and tunopen() grabbed that unit
before tunclose() finished (one process is allocating it while another
is freeing it!).

It may be worth hanging some sort of rw mutex around all specinfo
calls where d_close and the detach handler get a write lock and all
other functions get a read lock.  This would guarantee certain levels
of ``atomicity'' (is that a word?) that people may expect (I believe
Solaris does something like this).
