commit 8a27f7c90ffcb791eed7574922b51fb60b08fc89
changed the output style of %pi4 to use fixed
width leading zero IP addresses "001.002.003.004".
It's useful when printing multiple lines of
addresses, but was a change in output style for
some existing uses.
Using %pI4 restores the previous output style.

The first argument is the address family, the second one the hook
number.

Passive OS fingerprinting netfilter module allows to passively detect
remote OS and perform various netfilter actions based on that knowledge.
This module compares some data (WS, MSS, options and it's order, ttl, df
and others) from packets with SYN bit set with dynamically loaded OS
fingerprints.
Fingerprint matching rules can be downloaded from OpenBSD source tree
or found in archive and loaded via netfilter netlink subsystem into
the kernel via special util found in archive.
Archive contains library file (also attached), which was shipped
with iptables extensions some time ago (at least when ipt_osf existed
in patch-o-matic).
Following changes were made in this release:
* added NLM_F_CREATE/NLM_F_EXCL checks
* dropped _rcu list traversing helpers in the protected add/remove calls
* dropped unneded structures, debug prints, obscure comment and check
Fingerprints can be downloaded from
http://www.openbsd.org/cgi-bin/cvsweb/src/etc/pf.os
or can be found in archive
Example usage:
-d switch removes fingerprints
Please consider for inclusion.
Thank you.
