router so back out the routing stuff to pre-eurobsdcon where my machine
doesn't crash immediately.
i am happy to test diffs and report success/failures but i am not happy
to have instantaneous crashes when i reboot with a new kernel that was
compiled from pristine sources.
if you are going to be an elitist asshole then you could at least make
sure your code works.

the code took a shortcut which results in the new device not beeing added
to its interface class group as it should.
call the regular if_clone_create() instead of taking shortcuts, and all is
fine.

we're breaking pfsync compatibility this cycle anyways.
Requested by djm@, ok henning@, 'wheee!' deraadt@

bpf FILDROP interface exists for about one year but the required
interface to the drivers was missing - so it was useless. this new
approach based on a design by henning@ uses a new mbuf flag to mark
filtered packets and to drop them in the generic network stack input
routines (like ether_input).
for example; after some additional testing, this could be used by
dhclient to filter everything except DHCP packets (track tech@
for a corresponding dhclient diff). the "filter dropped" packets won't
reach the network stack. so it's probably some kind of a very basic
application layer packet filter ;).

Oh. and a KNF nit.

Applies only to rules in the main ruleset (not anchors) if the ruleset
checksum matches. Necessary to fix the following for pfsync'd states:
- per-rule limits on number of states
- altq
- rule-based settings such as timeouts
More work to do re: nat rules, src-nodes, etc.
NOTE: This is modifies the pfsync header and version number.
Tools which process pfsync packets must be recompiled, and firewalls with
different versions will not sync.

and calculate the modulator. This ensures that modulated initial sequence
numbers have the same properties regarding separation and non-repetition as
those generated by our TCP stack.

The previous code could wrongly delete multicast groups
on the parent interface. Now we forward only remembered
delete requests.

in the data part for the data from the previously distinct tags.
look up the tag early and carry a pointer to it around.

- Introduces a rw_lock in pfioctl so that we can have concurrent readers
but only one process performing updates at a time;
- Separates state expiry into "unlink" and "free" parts; anyone can unlink
a state/src node from the RB trees at any time, but a state can only be
freed whilst the write lock is held;
- Converts state_updates into list state_list containing all states,
regardless of whether they are "linked" or "unlinked";
- Introduces a new PFTM_UNLINKED state that is used on the "unlinked" states
to signal that they can be freed;
- Converts pf_purge_expired_state to an "unlink" state routine, which only
unlinks the state from the RB trees. Freeing the state/src nodes is left
to the purge thread, which runs whilst holding a write lock, such that all
"next" references remain valid;
- Converts pfsync_bulk_update and DIOCGETSTATES to walk state_list rather
than the RB trees;
- Converts the purge thread to use the new state_list and perform a partial
purge every second, with the target rate a full state table walk every
PFTM_INTERVAL seconds.

- add multicast support by passing multicast addresses to the ports.
this is a requirement for carp(4) over trunk(4).
- support the smallest common interface capabilities. ie., this adds
support for VLAN MTUs if all attached ports have this capability.
- add a port_destroy callback to the trunk protocol. this fixes a
potential crash if the master port has been detached while running.
discussed with deraadt@, brad@ and some others.

(similar to proxy ports for tcp/udp). not all clients use per-invokation

to search for a particular entry in the RB trees are at the start of the
structure.
This permits us to place a much smaller structure on the stack in the
interrupt paths that match packets against state entries.
