mean "prio is 0". This avoids the need for code changes in programs which add
pf rules (as was done in pfctl but not other programs) to handle the new
"check prio" functionality. Specifically this unbreaks ftp-proxy.
Use of #define rather than magic 0xff suggested by benno.

is a debug tool change of semantics not considered problematic.
up until now, log(matches) forced logging on subsequent matching rules,
the actual logging used the log settings from that matched rule.
now, log(matches) causes subsequent matches to be logged with the log settings
from the log(matches) rule. in particular (this was the driving point),
log(matches, to pflog23) allows you to have the trace log going to a seperate
pflog interface, not clobbering your regular pflogs, actually not affecting
them at all.
long conversation with bluhm about it, which didn't lead to a single bit
changed in the diff but was very very helpful. ok bluhm as well.

no real compat issue since we're using spare bytes.
old -> new ends up with set prio (0, 0) equivalent
new -> old is entirely harmless, old ignores the prios.

i. e. on vlan interfaces, it is useful to be able to match on it -
effectively matching on classification done elsewhere.
i thought i had long implemented that, but chrisz@ asking for it made
me notice that wasn't the case.

This finally allows to use source-hash for dynamic loadbalancing, eg.
"rdr-to <hosts> source-hash", instead of just round-robin and least-states.
An older pre-siphash version of this diff was tested by many people.

function pflog_bpfcopy() is setting up a packet description with
pf_setup_pdesc(). When pf_setup_pdesc() is droppig a bad packet,
it increments the the pf status counters. This way bad packets
could be accounted multiple times. Now pflog_bpfcopy() passes a
reason pointer NULL to indicate that no accounting should be done.

anchors for "once" rules: "In case this is the only rule in the
anchor, the anchor will be destroyed automatically after the rule
is matched." Employ an additional pointer pair to keep track of
the parent ruleset containing the anchor that we want to remove.

if.h even more messy for the transition, but eventuelly it should become
readable...

Start the expire counter when the queue is created by the first

under some circumstances repair broken checksums on the way.
ok ryan naddy mikeb
.
redo most of the protocol (tcp/udp/...) checksum handling
-assume we have hardware checksum offloading. stop mucking with the
checksum in most of the stack
-stop checksum mucking in pf, just set a "needs checksumming" flag if needed
-in all output pathes, very late, if we figure out the outbound interface
doesn't have hw cksum offloading, do the cksum in software. this especially
makes the bridge path behave like a regular output path
-little special casing for bridge still required until the broadcast path
loses its disgusting shortcut hacks, but at least it's in one place now
and not all over the stack
in6_proto_cksum_out mostly written by krw@
started at k2k11 in iceland more than 1.5 years ago - yes it took that
long, this stuff is everything but easy.
this happens to fix the infamous pf rdr bug that made us turn off proto
cksum offloading on almost all interface drivers.

sorry for the breakage, folks. found by tedu, SMSing me out of my breakfast

we stepped into a child anchor.
simplify the logic, get rid of the match flag in the anchor stack, just
use the match variable we already had (and used in a boolean style) to track
the nest level we had a match at. when a child anchor had a match we also
have a match in the current anchor, so update the match level accordingly,
and thus correctly honour the quick flag.
reported by, along with the right idea on how to fix this, by Sean Gallagher
\sean at teletech.com.au/, who also helped testing the fix. ok ryan & benno

these days, so:
-move the prototypes from pfvar.h to pf.c
-remove the now useless null point checks for *match, it is always provided

key we need to sync our state key pointers with whatever values
the function will pick. Not doing so will produce wrong results
if address translation must be applied afterwards and we happen
to have a state key collision. Then pf_translate will follow an
old pointer and punch in garbage addresses into the packet.

This sets the default to 25% of the mbuf cluster maximum (hint
from beck). And the example in the manpage is sane now.

"not set" and used a PF_PRIO_NOTSET define for it. now that means that
everything that creates a struct pf_rule doesn't get away with bzero'ing it,
which turned out to be not so nice. so get rid of PF_PRIO_NOTSET, instead,
make a rule+state flag PFSTATE_SETPRIO which indicates wether the prio
should be set. ok benno claudio mikeb
