matches the counters on states now. also fix the counting on scrub rules
where we previously did not handle the byte counters at all.
extend pfctl -sl output to include the new seperate in/out counters

check from there).

inserted the rule which causes the logging. secondly, the uid/pid of the
process in case the logged packet is delivered to/from a local socket.
a lookup of the local socket can be forced for logged packets with a new
option, 'log (user)'. make tcpdump print the additional information when
-e and -v is used. note: this changes the pflog header struct, rebuild all
dependancies. ok bob@, henning@.

allocator and two pools, but PR_WAITOK when called from non-interrupt
context (ioctl). add configurable hard limits for tables and table
entries (set limit tables/table-entries), defaulting to 1000/100000.

useless layers of indirection and make the code way cleaner overall.
this is just the start, more to come...
worked very hard on by Ryan and me in Montreal last week, on the airplane to
vancouver and yesterday here in calgary. it hurt.

they are reset to default values if omitted from a subsequent ruleset load.
Also:
- make sure 'set ...' options are not loaded in anchors.
- add a -m ("merge") flag to pfctl which allows an individual option to be set
without reseting the others, eg:
# echo "set loginterface fxp0" | pfctl -mf -

- remove identical and subsetted rules
- when advantageous merge rules w/ similar addresses into a table and one rule
- re-order rules to improve skip step performance (can do better w/ kernel mods)
- 'pfctl -oo' will load the currently running ruleset and use it as a profile
to direct the optimization of quicked rules

source-tracking. Found by Pyun YongHyeon.
Also add support to pfctl to set the src-nodes pool limit.
"Luckily" some of the bugs cancel each other out; update kernel before
pfctl.

1) PF should do the right thing when unplugging/replugging or cloning/
destroying NICs.
2) Rules can be loaded in the kernel for not-yet-existing devices
(USB, PCMCIA, Cardbus). For example, it is valid to write:
"pass in on kue0" before kue USB is plugged in.
3) It is possible to write rules that apply to group of interfaces
(drivers), like "pass in on ppp all"
4) There is a new ":peer" modifier that completes the ":broadcast"
and ":network" modifiers.
5) There is a new ":0" modifier that will filter out interface aliases.
Can also be applied to DNS names to restore original PF behaviour.
6) The dynamic interface syntax (foo) has been vastly improved, and
now support multiple addresses, v4 and v6 addresses, and all userland
modifiers, like "pass in from (fxp0:network)"
7) Scrub rules now support the !if syntax.
8) States can be bound to the specific interface that created them or
to a group of interfaces for example:
- pass all keep state (if-bound)
- pass all keep state (group-bound)
- pass all keep state (floating)
9) The default value when only keep state is given can be selected by
using the "set state-policy" statement.
10) "pfctl -ss" will now print the interface scope of the state.
This diff change the pf_state structure slighltly, so you should
recompile your userland tools (pfctl, authpf, pflogd, tcpdump...)

Implemented as an in-kernel multicast IP protocol.
Turn it on like this:
# ifconfig pfsync0 up syncif fxp0
There is not yet any authentication on this protocol, so the syncif
must be on a trusted network. ie, a crossover cable between the two
firewalls.
NOTABLE CHANGES:
- A new index based on a unique (creatorid, stateid) tuple has been
added to the state tree.
- Updates now appear on the pfsync(4) interface; multiple updates may
be compressed into a single update.
- Applications which use bpf on pfsync(4) will need modification;
packets on pfsync no longer contains regular pf_state structs,
but pfsync_state structs which contain no pointers.
Much more to come.
