+=head1 NAME
+
+C<NetPacket::PFLog> - Assembling and disassembling OpenBSD's Packet
+Filter log header.
+
+=head1 SYNOPSIS
+
+ use NetPacket::PFLog;
+
+ $pfl_obj = NetPacket::PFLog->decode($raw_pkt);
+ $pfl_pkt = NetPacket::PFLog->encode();
+ $pfl_data = NetPacket::PFLog::strip($raw_pkt);
+
+=head1 DESCRIPTION
+
+C<NetPacket::PFLog> provides a set of routines for assembling and
+disassembling the header attached to packets logged by OpenBSD's
+Packet Filter.
+
+=head2 Methods
+
+=over
+
+=item C<NetPacket::PFLog-E<gt>decode([RAW PACKET])>
+
+Decode the raw packet data given and return an object containing
+instance data. This method will quite happily decode garbage input. It
+is the responsibility of the programmer to ensure valid packet data is
+passed to this method.
+
+=item C<NetPacket::PFLog-E<gt>encode()>
+
+Return a PFLog packet encoded with the instance data specified.
+
+=back
+
+=head2 Functions
+
+=over
+
+=item C<NetPacket::PFLog::strip([RAW PACKET])>
+
+Return the actual packet logged by Packet Filter that the PFLog header
+is describing. This data is suitable to be used as input for other
+C<NetPacket::*> modules.
+
+This function is equivalent to creating an object using the
+C<decode()> constructor and returning the C<data> field of that
+object.
+
+=back
+
+=head2 Instance data
+
+The instance data for the C<NetPacket::PFLog> object consists of
+the following fields:
+
+=over
+
+=item len
+
+The length of the pflog header.
+
+=item af
+
+The Address Family which denotes if the packet is IPv4 or IPv6.
+
+=item action
+
+The action (block, pass, or scrub) that was taken on the packet.
+
+=item reason
+
+The reason that the action was taken.
+
+=item ifname
+
+The name of the interface the packet was passing through.
+
+=item ruleset
+
+The name of the subruleset that the matching rule is a member of. If
+the value is empty, the matching rule is in the main ruleset.
+
+=item rulenr
+
+The rule number that the packet matched.
+
+=item subrulenr
+
+The rule number in the subruleset that the packet matched. The value
+will be 2^32-1 if the packet matched in the main ruleset only.
+
+=item uid
+
+The uid of the process that inserted the rule that caused the packet to be
+logged.
+
+=item pid
+
+The pid of the process that inserted the rult that caused the packet to be
+logged.
+
+=item rule_uid
+
+The uid of the local process that generated the packet that was logged, if
+applicable.
+
+=item rule_pid
+
+The pid of the local process that generated the packer that was logged, if
+applicable.
+
+=item dir
+
+The direction the packet was travelling through the interface.
+
+=item pad
+
+Padding data.
+
+=item data
+
+The actual IPv4 or IPv6 packet that was logged by Packet Filter.
+
+=back
+
+=head2 Exports
+
+=over
+
+=item default
+
+none
+
+=item exportable
+
+Data Link Type:
+
+ DLT_PFLOG
+
+Strip function:
+
+ pflog_strip
+
+=item tags
+
+The following tags can be used to export certain items:
+
+=over
+
+=item C<:DLT>
+
+DLT_PFLOG
+
+=item C<:strip>
+
+The function C<pflog_strip>
+
+=item C<:ALL>
+
+All the above exportable items
+
+=back
+
+=back
+
+=head1 EXAMPLE
+
+The following prints the action, direction, interface name, and
+reason:
+
+ #!/usr/bin/perl -w
+
+ use strict;
+ use Net::PcapUtils;
+ use NetPacket::PFLog;
+
+ sub process_pkt {
+ my ($user, $hdr, $pkt) = @_;
+
+ my $pfl_obj = NetPacket::PFLog->decode($pkt);
+ print("$pfl_obj->{action} $pfl_obj->{dir} ");
+ print("on $pfl_obj->{ifname} ($pfl_obj->{reason})\n");
+ }
+
+ Net::PcapUtils::loop(\&process_pkt, FILTER => 'ip or ip6');
+
+=head1 TODO
+
+Nothing at this time.

"NetPacket" provides a base class for a cluster of modules related to
decoding and encoding of network protocols. Each "NetPacket" descendent
module knows how to encode and decode packets for the network protocol
it implements. Consult the documentation for the module in question for
protocol-specific implementation.
