4 Version 1.0: August 11, 1996 (cjm)
6 Version 1.1: August 20, 1996 (cjm)
7 - Host accepts incoming connections for ports 0 to 1023.
9 Version 1.2: September 7, 1996 (cjm)
10 - Fragment handling error in alias_db.c corrected.
12 Version 1.3: September 15, 1996 (cjm)
13 - Generalized mechanism for handling incoming
14 connections (no more 0 to 1023 restriction).
16 - Increased ICMP support (will handle traceroute now).
18 - Improved TCP close connection logic.
20 Version 1.4: September 16, 1996 (cjm)
22 Version 1.5: September 17, 1996 (cjm)
23 - Corrected error in handling incoming UDP packets
26 Version 1.6: September 18, 1996
27 - Simplified ICMP data storage. Will now handle
28 tracert from Win95 and NT as well as FreeBSD
29 traceroute, which uses UDP packets to non-existent
32 Version 1.7: January 9, 1997 (cjm)
33 - Reduced malloc() activity for ICMP echo and
36 - Added handling for out-of-order IP fragments.
38 - Switched to differential checksum computation
39 for IP headers (TCP, UDP and ICMP checksums
40 were already differential).
42 - Accepts FTP data connections from other than
43 port 20. This allows one ftp connections
44 from two hosts which are both running packet
47 - Checksum error on FTP transfers. Problem
48 in code located by Martin Renters and
51 Version 1.8: January 14, 1997 (cjm)
52 - Fixed data type error in function StartPoint()
53 in alias_db.c (this bug did not exist before v1.7)
54 Problem in code located by Ari Suutari.
56 Version 1.9: February 1, 1997 (Eivind Eklund <perhaps@yes.no>)
57 - Added support for IRC DCC (ee)
59 - Changed the aliasing routines to use ANSI style
62 - Minor API changes for integration with other
63 programs than PPP (ee)
65 - Fixed minor security hole in alias_ftp.c for
66 other applications of the aliasing software.
67 Hole could _not_ manifest in ppp+pktAlias, but
68 could potentially manifest in other applications
71 - Connections initiated from packet aliasing
72 host machine will not have their port number
73 aliased unless it conflicts with an aliasing
74 port already being used. (There is an option
75 to disable this for debugging) (cjm)
77 - Sockets will be allocated in cases where
78 there might be port interference with the
79 host machine. This can be disabled in cases
80 where the ppp host will be acting purely as a
81 masquerading router and not generate any
85 Version 2.0: March, 1997 (cjm)
86 - Aliasing links are cleared only when a host interface address
89 - PacketAliasPermanentLink() API added.
91 - Option for only aliasing private, unregistered
94 - Substantial rework to the aliasing lookup engine.
96 Version 2.1: May, 1997 (cjm)
97 - Continuing rework to the aliasing lookup engine
98 to support multiple incoming addresses and static
99 NAT. PacketAliasRedirectPort() and
100 PacketAliasRedirectAddr() added to API.
102 - Now supports outgoing as well as incoming ICMP
105 Version 2.2: July, 1997 (cjm)
106 - Rationalized API function names to all begin with
107 "PacketAlias..." Old function names are retained
108 for backwards compatibility.
110 - Packet aliasing engine will now free memory of
111 fragments which are never resolved after a timeout
112 period. Once a fragment is resolved, it becomes
113 the users responsibility to free the memory.
115 Version 2.3: August 11, 1997 (cjm)
116 - Problem associated with socket file descriptor
117 accumulation in alias_db.c corrected. The sockets
118 had to be closed when a binding failed. Problem
119 in code located by Gordon Burditt.
121 Version 2.4: September 1, 1997 (cjm)
122 - PKT_ALIAS_UNREGISTERED_ONLY option repaired.
123 This part of the code was incorrectly re-implemented
126 Version 2.5: December, 1997 (ee)
127 - Added PKT_ALIAS_PUNCH_FW mode for firewall
128 bypass of FTP/IRC DCC data connections. Also added
129 improved TCP connection monitoring.
131 Version 2.6: May, 1998 (amurai)
132 - Added supporting routine for NetBios over TCP/IP.
134 Version 3.0: January 1, 1999
135 - Transparent proxying support added.
136 - PPTP redirecting support added based on patches
137 contributed by Dru Nelson <dnelson@redwoodsoft.com>.
139 Version 3.1: May, 2000 (Erik Salander, erik@whistle.com)
140 - Added support to alias 227 replies, allows aliasing for
141 FTP servers in passive mode.
142 - Added support for PPTP aliasing.
144 Version 3.2: July, 2000 (Erik Salander, erik@whistle.com and
145 Junichi Satoh, junichi@junichi.org)
146 - Added support for streaming media (RTSP and PNA) aliasing.
