9b39baf16c Try to make the `syn' blocking code act a bit more sensibly - don't 
block `syn' packets that have `ack' set.

de86e24516 Fixed panic that occurs on certain firewall rejected packets that was 
caused by dtom() being used on an mbuf cluster. The fix involves passing
around the mbuf pointer.

5d30bb533f This is the end result of about a dozen passes through this code to fix 
incorrect indents, a variety of poor coding practices such as comparing
pointers to constants ('0'), poor code structuring, etc, etc. This brings
the code up to the minimum standards for inclusion in FreeBSD.

c200b4b97b 1) Removed bogus #include 
2) Rewrote "bad_packet" code to be less buggy and more readable.
3) Removed a pile of goto's; the code is now somewhat less reminiscent
   of a certain Italian pasta.
4) Changed all boolean returns of "0" and "1" to FALSE/TRUE.

dd3cca2bda Actual firewall change. 
1) Firewall is not subdivided on forwarding / blocking chains
   anymore.Actually only one chain left-it was the blocking one.
2) LKM support.ip_fwdef.c is function pointers definition and
goes into kernel along with all INET stuff.

e8b4c66232 Ugen J.S.Antsilevich's latest, happiest, IP firewall code. 
Poul:  Please take this into BETA.  It's non-intrusive, and a rather
substantial improvement over what was there before.

319fc7e1e0 2 11th-hour fixes from Ugen (not Uben, sorry!) J.S.Antsilevich. 
I think it's time for Ugen to get a freefall account, just so I can
direct mail at him directly and let him drop off patches for us here.  Ugen?
Done!
