xt_osf is pretty useless without the actual fingerprint loader. Import
nfnl_osf-2009-06-07 and make it a part of the iptables distribution.

+#
+#
+# This fingerprint database is adapted from Michal Zalewski's p0f passive
+# operating system package. The last database sync was from a Nov 3 2003
+# p0f.fp.
+#
+#
+# Each line in this file specifies a single fingerprint. Please read the
+# information below carefully before attempting to append any signatures
+# reported as UNKNOWN to this file to avoid mistakes.
+#
+# We use the following set metrics for fingerprinting:
+#
+# - Window size (WSS) - a highly OS dependent setting used for TCP/IP
+# performance control (max. amount of data to be sent without ACK).
+# Some systems use a fixed value for initial packets. On other
+# systems, it is a multiple of MSS or MTU (MSS+40). In some rare
+# cases, the value is just arbitrary.
+#
+# NEW SIGNATURE: if p0f reported a special value of 'Snn', the number
+# appears to be a multiple of MSS (MSS*nn); a special value of 'Tnn'
+# means it is a multiple of MTU ((MSS+40)*nn). Unless you notice the
+# value of nn is not fixed (unlikely), just copy the Snn or Tnn token
+# literally. If you know this device has a simple stack and a fixed
+# MTU, you can however multiply S value by MSS, or T value by MSS+40,
+# and put it instead of Snn or Tnn.
+#
+# If WSS otherwise looks like a fixed value (for example a multiple
+# of two), or if you can confirm the value is fixed, please quote
+# it literally. If there's no apparent pattern in WSS chosen, you
+# should consider wildcarding this value.
+#
+# - Overall packet size - a function of all IP and TCP options and bugs.
+#
+# NEW SIGNATURE: Copy this value literally.
+#
+# - Initial TTL - We check the actual TTL of a received packet. It can't
+# be higher than the initial TTL, and also shouldn't be dramatically
+# lower (maximum distance is defined as 40 hops).
+#
+# NEW SIGNATURE: *Never* copy TTL from a p0f-reported signature literally.
+# You need to determine the initial TTL. The best way to do it is to
+# check the documentation for a remote system, or check its settings.
+# A fairly good method is to simply round the observed TTL up to
+# 32, 64, 128, or 255, but it should be noted that some obscure devices
+# might not use round TTLs (in particular, some shoddy appliances use
+# "original" initial TTL settings). If not sure, you can see how many
+# hops you're away from the remote party with traceroute or mtr.
+#
+# - Don't fragment flag (DF) - some modern OSes set this to implement PMTU
+# discovery. Others do not bother.
+#
+# NEW SIGNATURE: Copy this value literally.
+#
+# - Maximum segment size (MSS) - this setting is usually link-dependent. P0f
+# uses it to determine link type of the remote host.
+#
+# NEW SIGNATURE: Always wildcard this value, except for rare cases when
+# you have an appliance with a fixed value, know the system supports only
+# a very limited number of network interface types, or know the system
+# is using a value it pulled out of nowhere. Specific unique MSS
+# can be used to tell Google crawlbots from the rest of the population.
+#
+# - Window scaling (WSCALE) - this feature is used to scale WSS.
+# It extends the size of a TCP/IP window to 32 bits. Some modern
+# systems implement this feature.
+#
+# NEW SIGNATURE: Observe several signatures. Initial WSCALE is often set
+# to zero or other low value. There's usually no need to wildcard this
+# parameter.
+#
+# - Timestamp - some systems that implement timestamps set them to
+# zero in the initial SYN. This case is detected and handled appropriately.
+#
+# - Selective ACK permitted - a flag set by systems that implement
+# selective ACK functionality.
+#
+# - The sequence of TCP all options (MSS, window scaling, selective ACK
+# permitted, timestamp, NOP). Other than the options previously
+# discussed, p0f also checks for timestamp option (a silly
+# extension to broadcast your uptime ;-), NOP options (used for
+# header padding) and sackOK option (selective ACK feature).
+#
+# NEW SIGNATURE: Copy the sequence literally.
+#
+# To wildcard any value (except for initial TTL or TCP options), replace
+# it with '*'. You can also use a modulo operator to match any values
+# that divide by nnn - '%nnn'.
+#
+# Fingerprint entry format:
+#
+# wwww:ttt:D:ss:OOO...:OS:Version:Subtype:Details
+#
+# wwww - window size (can be *, %nnn, Snn or Tnn). The special values
+# "S" and "T" which are a multiple of MSS or a multiple of MTU
+# respectively.
+# ttt - initial TTL
+# D - don't fragment bit (0 - not set, 1 - set)
+# ss - overall SYN packet size
+# OOO - option value and order specification (see below)
+# OS - OS genre (Linux, Solaris, Windows)
+# Version - OS Version (2.0.27 on x86, etc)
+# Subtype - OS subtype or patchlevel (SP3, lo0)
+# details - Generic OS details
+#
+# If OS genre starts with '*', p0f will not show distance, link type
+# and timestamp data. It is useful for userland TCP/IP stacks of
+# network scanners and so on, where many settings are randomized or
+# bogus.
+#
+# If OS genre starts with @, it denotes an approximate hit for a group
+# of operating systems (signature reporting still enabled in this case).
+# Use this feature at the end of this file to catch cases for which
+# you don't have a precise match, but can tell it's Windows or FreeBSD
+# or whatnot by looking at, say, flag layout alone.
+#
+# Option block description is a list of comma or space separated
+# options in the order they appear in the packet:
+#
+# N - NOP option
+# Wnnn - window scaling option, value nnn (or * or %nnn)
+# Mnnn - maximum segment size option, value nnn (or * or %nnn)
+# S - selective ACK OK
+# T - timestamp
+# T0 - timestamp with a zero value
+#
+# To denote no TCP options, use a single '.'.

+# WARNING WARNING WARNING
+# -----------------------
+#
+# Do not add a system X as OS Y just because NMAP says so. It is often
+# the case that X is a NAT firewall. While nmap is talking to the
+# device itself, p0f is fingerprinting the guy behind the firewall
+# instead.
+#
+# When in doubt, use common sense, don't add something that looks like
+# a completely different system as Linux or FreeBSD or LinkSys router.
+# Check DNS name, establish a connection to the remote host and look
+# at SYN+ACK - does it look similar?
+#
+# Some users tweak their TCP/IP settings - enable or disable RFC1323
+# functionality, enable or disable timestamps or selective ACK,
+# disable PMTU discovery, change MTU and so on. Always compare a new rule
+# to other fingerprints for this system, and verify the system isn't
+# "customized" before adding it. It is OK to add signature variants
+# caused by a commonly used software (personal firewalls, security
+# packages, etc), but it makes no sense to try to add every single
+# possible /proc/sys/net/ipv4 tweak on Linux or so.
+#
+# KEEP IN MIND: Some packet firewalls configured to normalize outgoing
+# traffic (OpenBSD pf with "scrub" enabled, for example) will, well,
+# normalize packets. Signatures will not correspond to the originating
+# system (and probably not quite to the firewall either).
+#
+# NOTE: Try to keep this file in some reasonable order, from most to
+# least likely systems. This will speed up operation. Also keep most
+# generic and broad rules near the end.
