639  formats.
640
641- Extend OSF ip header workaround to versions 1 and 2.

693  Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
694
695- Rewrite ospf printer to improve truncation checks.
696
697- Don't parse tcp options past the EOL. As noted by David Sacerdote
698  (davids@secnet.com). Also, check tcp options to make sure they ar
699  actually in the tcp header (in addition to the normal truncation
700  checks). Fix the SACK code to print the N blocks (instead of the
701  first block N times).
702
703- Don't say really small UDP packets are truncated just because they
704  aren't big enough to be a RPC. As noted by David Sacerdote.
705

732  Thanks to John Hawkinson.
733
734- Added some more packet truncation checks.
735

827  exit with a bad status if there were problems.
828
829- Bail if ip option length is <= 0. Resulted from a bug report from
830  Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au).

885
886- Change configuration to not use gcc v2 flags with gcc v1.
887
888- Redo gmt2local() so that it works under BSDI (which seems to return
889  an empty timezone struct from gettimeofday()). Based on report from
890  Terry Kennedy (terry@spcvxa.spc.edu).
891
892- Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
893  on report from Mark Andrews (mandrews@alias.com).
894
895- Don't pass cc flags to gcc. Resulted from a bug report from Rainer
896  Orth (ro@techfak.uni-bielefeld.de).

910
911- Added support for printing tcp option timestamps thanks to
912  Mark Andrews (mandrews@alias.com).
913
914- Reorganize protocol dumpers to take const pointers to packets so they
915  never change the contents (i.e., they used to do endian conversions
916  in place).  Previously, whenever more than one pass was taken over
917  the packet, the packet contents would be dumped incorrectly (i.e.,
918  the output form -x would be wrong on little endian machines because
919  the protocol dumpers would modify the data).  Thanks to Charles Hannum
920  (mycroft@gnu.ai.mit.edu) for reporting this problem.
921
922- Added support for decnet protocol dumping thanks to Jeff Mogul
923  (mogul@pa.dec.com).

926  (off by ether header size) for unknown ethernet types thanks
927  to Greg Miller (gmiller@kayak.mitre.org).
928
929- Added support for IPX protocol dumping thanks to Brad Parker
930  (brad@fcr.com).
931
932- Added check to verify IP header checksum under -v thanks to
933  Brad Parker (brad@fcr.com).
934
935- Move packet capture code to new libpcap library (which is
936  packaged separately).
937
938- Prototype everything and assume an ansi compiler.
939
940- print-arp.c: Print hardware ethernet addresses if they're not
941  what we expect.
942
943- print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
944  Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
945
946- print-fddi.c: Improvements. Thanks to Jeffrey Mogul
947  (mogul@pa.dec.com).
948
949- print-icmp.c: Byte swap netmask before printing. Thanks to
950  Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
951
952- print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
953  By default, only the inner packet is dumped, appended with the token
954  "(encap)".  Under -v, both the inner and output packets are dumped
955  (on the same line).  Note that the filter applies to the original packet,
956  not the encapsulated packet.  So if you run tcpdump on a net with an
957  IP Multicast tunnel, you cannot filter out the datagrams using the
958  conventional syntax.  (You can filter away all the ip-in-ip traffic
959  with "not ip proto 4".)
960
961- print-nfs.c: Keep pending rpc's in circular table. Add generic
962  nfs header and remove os dependences. Thanks to Jeffrey Mogul.
963
964- print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
965
966- tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
967  (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
968  Add && and || operators
969
970v2.2.1 Tue Jun 6 17:57:22 PDT 1992
971
972- Fix bug with -c flag.
973
974v2.2 Fri May 22 17:19:41 PDT 1992
975
976- savefile.c: Remove hack that shouldn't have been exported. Add
977  truncate checks.
978
979- Added the 'icmp' keyword.  For example, 'icmp[0] != 8 and icmp[0] != 0'
980  matches non-echo/reply ICMP packets.
981
982- Many improvements to filter code optimizer.
983
984- Added 'multicast' keyword and extended the 'broadcast' keyword can now be
985  so that protocol qualifications are allowed. For example, "ip broadcast"
986  and "ether multicast" are valid filters.
987
988- Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
989  Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
990  patches to netinet/if_loop.c.
991
992- Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
993  Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
994
995- Added EGP and OSPF printers, thanks to Jeffrey Honig.
996
997v2.1 Tue Jan 28 11:00:14 PST 1992
998
999- Internal release (never publically exported).
1000
1001v2.0.1 Sun Jan 26 21:10:10 PDT
1002
1003- Various byte ordering fixes.
1004
1005- Add truncation checks.
1006
1007- inet.c: Support BSD style SIOCGIFCONF.
1008
1009- nametoaddr.c: Handle multi addresses for single host.
1010
1011- optimize.c: Rewritten.
1012
1013- pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1014  for broadcast nets.
1015
1016- print-atal.c: Fix an alignment bug (thanks to
1017  stanonik@nprdc.navy.mil) Add missing printf() argument.
1018
1019- print-bootp.c: First attempt at decoding the vendor buffer.
1020
1021- print-domain.c: Fix truncation checks.
1022
1023- print-icmp.c: Calculate length of packets from the ip header.
1024
1025- print-ip.c: Print frag id in decimal (so it's easier to match up
1026  with non-frags). Add support for ospf, egp and igmp.
1027
1028- print-nfs.c: Lots of changes.
1029
1030- print-ntp.c: Make some verbose output depend on -v.
1031
1032- print-snmp.c: New version from John LoVerso.
1033
1034- print-tcp.c: Print rfc1072 tcp options.
1035
1036- tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1037  (microseconds) worth of precision. Fix uid bugs.
1038
1039- A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1040  With this option, you can create an architecture independent binary
1041  trace file in real time, without the overhead of the packet printer.
1042  At a later time, the packets can be filtered (again) and printed.
1043
1044- BSD is supported.  You must have BPF in your kernel.
1045  Since the filtering is now done in the kernel, fewer packets are
1046  dropped.  In fact, with BPF and the packet dumper option, a measly
1047  Sun 3/50 can keep up with a busy network.
1048
1049- Compressed SLIP packets can now be dumped, provided you use our
1050  SLIP software and BPF.  These packets are dumped as any other IP
1051  packet; the compressed headers are dumped with the '-e' option.
1052
1053- Machines with little-endian byte ordering are supported (thanks to
1054  Jeff Mogul).
1055
1056- Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1057
1058- IBM RT and Stanford Enetfilter support has been added by
1059  Rayan Zachariassen <rayan@canet.ca>.  Tcpdump has been tested under
1060  both the vanilla Enetfilter interface, and the extended interface
1061  (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1062
1063- TFTP packets are now printed (requests only).
1064
1065- BOOTP packets are now printed.
1066
1067- SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1068
1069- Sparc architectures, including the Sparcstation-1, are now
1070  supported thanks to Steve McCanne and Craig Leres.
1071
1072- SunOS 4 is now supported thanks to Micky Liu of Columbia
1073  University (micky@cunixc.cc.columbia.edu).
1074
1075- IP options are now printed.
1076
1077- RIP packets are now printed.
1078
1079- There's a -v flag that prints out more information than the
1080  default (e.g., it will enable printing of IP ttl, tos and id)
1081  and -q flag that prints out less (e.g., it will disable
1082  interpretation of AppleTalk-in-UDP).
1083
1084- The grammar has undergone substantial changes (if you have an
1085  earlier version of tcpdump, you should re-read the manual
1086  entry).
1087
1088  The most useful change is the addition of an expression
1089  syntax that lets you filter on arbitrary fields or values in the
1090  packet.  E.g., "ip[0] > 0x45" would print only packets with IP
1091  options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1092  packets.
1093
1094  The most painful change is that concatenation no longer means
1095  "and" -- e.g., you have to say "host foo and port bar" instead
1096  of "host foo port bar".  The up side to this down is that
1097  repeated qualifiers can be omitted, making most filter
1098  expressions shorter.  E.g., you can now say "ip host foo and
1099  (bar or baz)" to look at ip traffic between hosts foo and bar or
1100  between hosts foo and baz.  [The old way of saying this was "ip
1101  host foo and (ip host bar or ip host baz)".]
1102
1103v2.0 Sun Jan 13 12:20:40 PST 1991
1104
1105- Initial public release.
