| 3 | Version 1.0: August 11, 1996 (cjm)
|
|---|
| 4 |
|
|---|
| 5 | Version 1.1: August 20, 1996 (cjm)
|
|---|
| 6 | - Host accepts incoming connections for ports 0 to 1023.
|
|---|
| 7 |
|
|---|
| 8 | Version 1.2: September 7, 1996 (cjm)
|
|---|
| 9 | - Fragment handling error in alias_db.c corrected.
|
|---|
| 10 |
|
|---|
| 11 | Version 1.3: September 15, 1996 (cjm)
|
|---|
| 12 | - Generalized mechanism for handling incoming
|
|---|
| 13 | connections (no more 0 to 1023 restriction).
|
|---|
| 14 |
|
|---|
| 15 | - Increased ICMP support (will handle traceroute now).
|
|---|
| 16 |
|
|---|
| 17 | - Improved TCP close connection logic.
|
|---|
| 18 |
|
|---|
| 19 | Version 1.4: September 16, 1996 (cjm)
|
|---|
| 20 |
|
|---|
| 21 | Version 1.5: September 17, 1996 (cjm)
|
|---|
| 22 | - Corrected error in handling incoming UDP packets
|
|---|
| 23 | with zero checksum.
|
|---|
| 24 |
|
|---|
| 25 | Version 1.6: September 18, 1996
|
|---|
| 26 | - Simplified ICMP data storage. Will now handle
|
|---|
| 27 | tracert from Win95 and NT as well as FreeBSD
|
|---|
| 28 | traceroute, which uses UDP packets to non-existent
|
|---|
| 29 | ports.
|
|---|
| 30 |
|
|---|
| 31 | Version 1.7: January 9, 1997 (cjm)
|
|---|
| 32 | - Reduced malloc() activity for ICMP echo and
|
|---|
| 33 | timestamp requests.
|
|---|
| 34 |
|
|---|
| 35 | - Added handling for out-of-order IP fragments.
|
|---|
| 36 |
|
|---|
| 37 | - Switched to differential checksum computation
|
|---|
| 38 | for IP headers (TCP, UDP and ICMP checksums
|
|---|
| 39 | were already differential).
|
|---|
| 40 |
|
|---|
| 41 | - Accepts FTP data connections from other than
|
|---|
| 42 | port 20. This allows one ftp connections
|
|---|
| 43 | from two hosts which are both running packet
|
|---|
| 44 | aliasing.
|
|---|
| 45 |
|
|---|
| 46 | - Checksum error on FTP transfers. Problem
|
|---|
| 47 | in code located by Martin Renters and
|
|---|
| 48 | Brian Somers.
|
|---|
| 49 |
|
|---|
| 50 | Version 1.8: January 14, 1997 (cjm)
|
|---|
| 51 | - Fixed data type error in function StartPoint()
|
|---|
| 52 | in alias_db.c (this bug did not exist before v1.7)
|
|---|
| 53 | Problem in code located by Ari Suutari.
|
|---|
| 54 |
|
|---|
| 55 | Version 1.9: February 1, 1997 (Eivind Eklund <[email protected]>)
|
|---|
| 56 | - Added support for IRC DCC (ee)
|
|---|
| 57 |
|
|---|
| 58 | - Changed the aliasing routines to use ANSI style
|
|---|
| 59 | throughout (ee)
|
|---|
| 60 |
|
|---|
| 61 | - Minor API changes for integration with other
|
|---|
| 62 | programs than PPP (ee)
|
|---|
| 63 |
|
|---|
| 64 | - Fixed minor security hole in alias_ftp.c for
|
|---|
| 65 | other applications of the aliasing software.
|
|---|
| 66 | Hole could _not_ manifest in ppp+pktAlias, but
|
|---|
| 67 | could potentially manifest in other applications
|
|---|
| 68 | of the aliasing. (ee)
|
|---|
| 69 |
|
|---|
| 70 | - Connections initiated from packet aliasing
|
|---|
| 71 | host machine will not have their port number
|
|---|
| 72 | aliased unless it conflicts with an aliasing
|
|---|
| 73 | port already being used. (There is an option
|
|---|
| 74 | to disable this for debugging) (cjm)
|
|---|
| 75 |
|
|---|
| 76 | - Sockets will be allocated in cases where
|
|---|
| 77 | there might be port interference with the
|
|---|
| 78 | host machine. This can be disabled in cases
|
|---|
| 79 | where the ppp host will be acting purely as a
|
|---|
| 80 | masquerading router and not generate any
|
|---|
| 81 | traffic of its own.
|
|---|
| 82 | (cjm)
|
|---|
| 83 |
|
|---|
| 84 | Version 2.0: March, 1997 (cjm)
|
|---|
| 85 | - Aliasing links are cleared only when a host interface address
|
|---|
| 86 | changes.
|
|---|
| 87 |
|
|---|
| 88 | - PacketAliasPermanentLink() API added.
|
|---|
| 89 |
|
|---|
| 90 | - Option for only aliasing private, unregistered
|
|---|
| 91 | IP addresses added.
|
|---|
| 92 |
|
|---|
| 93 | - Substantial rework to the aliasing lookup engine.
|
|---|
| 94 |
|
|---|
| 95 | Version 2.1: May, 1997 (cjm)
|
|---|
| 96 | - Continuing rework to the aliasing lookup engine
|
|---|
| 97 | to support multiple incoming addresses and static
|
|---|
| 98 | NAT. PacketAliasRedirectPort() and
|
|---|
| 99 | PacketAliasRedirectAddr() added to API.
|
|---|
| 100 |
|
|---|
| 101 | - Now supports outgoing as well as incoming ICMP
|
|---|
| 102 | error messages.
|
|---|
| 103 |
|
|---|
| 104 | Version 2.2: July, 1997 (cjm)
|
|---|
| 105 | - Rationalized API function names to all begin with
|
|---|
| 106 | "PacketAlias..." Old function names are retained
|
|---|
| 107 | for backwards compatibility.
|
|---|
| 108 |
|
|---|
| 109 | - Packet aliasing engine will now free memory of
|
|---|
| 110 | fragments which are never resolved after a timeout
|
|---|
| 111 | period. Once a fragment is resolved, it becomes
|
|---|
| 112 | the users responsibility to free the memory.
|
|---|
| 113 |
|
|---|
| 114 | Version 2.3: August 11, 1997 (cjm)
|
|---|
| 115 | - Problem associated with socket file descriptor
|
|---|
| 116 | accumulation in alias_db.c corrected. The sockets
|
|---|
| 117 | had to be closed when a binding failed. Problem
|
|---|
| 118 | in code located by Gordon Burditt.
|
|---|
| 119 |
|
|---|
| 120 | Version 2.4: September 1, 1997 (cjm)
|
|---|
| 121 | - PKT_ALIAS_UNREGISTERED_ONLY option repaired.
|
|---|
| 122 | This part of the code was incorrectly re-implemented
|
|---|
| 123 | in version 2.1.
|
|---|
| 124 |
|
|---|
| 125 | Version 2.5: December, 1997 (ee)
|
|---|
| 126 | - Added PKT_ALIAS_PUNCH_FW mode for firewall
|
|---|
| 127 | bypass of FTP/IRC DCC data connections. Also added
|
|---|
| 128 | improved TCP connection monitoring.
|
|---|
| 129 |
|
|---|
| 130 | Version 2.6: May, 1998 (amurai)

|
|---|
| 142 |
