$Header: /tcpdump/master/tcpdump/CHANGES,v 1.79 2001/01/10 20:13:58 mcr Exp $

Tuesday January 9, 2001. [e-mail]. Summary for 3.6 release
	Cleaned up documentation.
	Promisc mode fixes for Linux
	IPsec changes/cleanups.
	Alignment fixes for picky architectures

	Removed dependency on native headers for packet dissectors.
	Removed Linux specific headers that were shipped

	libpcap changes provide for exchanging capture files between
	  systems. Save files now have well known PACKET_ values instead of
	  depending upon system dependant mappings of DLT_* types.

	Support for computing/checking IP and UDP/TCP checksums.

	Updated autoconf stock files.

	IPv6 improvements: dhcp (draft-15), mobile-ip6, ppp, ospf6, 

	Added dissector support for: ISOCLNS, Token Ring, IGMPv3, bxxp,
		timed, vrrp, radius, chdlc, cnfp, cdp, IEEE802.1d, raw-AppleTalk

	Added filtering support for: VLANs, ESIS, ISIS

	Improvements to: print-telnet, IPTalk, bootp/dhcp, ECN, PPP,
		L2TP, PPPoE

	HP-UX 11.0 -- find the right dlpi device.
	Solaris 8 - IPv6 works
	Linux - Added support for an "any" device to capture on all interfaces
	
	Security fixes: buffer overrun audit done. Strcpy replaced with
		strlcpy, sprintf replaced with snprintf.
	Look for lex problems, and warn about them.

[e-mail]
- -X will make a ascii dump.  from netbsd.

Assar Westerlund  <[e-mail]>

Ken Hornstein <[e-mail]>
- bring in code at
  /afs/transarc.com/public/afs-contrib/tools/tcpdump for parsing
  AFS3 packets

Andrew Tridgell <[e-mail]>
- SMB printing code

Love <[e-mail]>

  change date format to the right one.

Michael C. Richardson  <[e-mail]>
- Created tcpdump.org repository

v3.4 Sat Jul 25 12:40:55 PDT 1998

- Hardwire Linux slip support since it's too hard to detect.

- Redo configuration of "network" libraries (-lsocket and -lnsl) to
  deal with IRIX. Thanks to John Hawkinson ([e-mail])

- Added -a which tries to translate network and broadcast addresses to
  names. Suggested by Rob van Nieuwkerk ([e-mail])

- Added a configure option to disable gcc.

- Added a "raw" packet printer.

- Not having an interface address is no longer fatal. Requested by John
  Hawkinson.

- Rework signal setup to accommodate Linux.

- OSPF truncation check fix. Also display the type of OSPF packets
  using MD5 authentication. Thanks to Brian Wellington
  ([e-mail])

- Fix truncation check bugs in the Kerberos printer. Reported by Ezra
  Peisach ([e-mail])

- Don't catch SIGHUP when invoked with nohup(1). Thanks to Dave Plonka
  ([e-mail])

- Specify full install target as a way of detecting if install
  directory does not exist. Thanks to Dave Plonka.

- Bit-swap FDDI addresses for BSD/OS too. Thanks to Paul Vixie
  ([e-mail])

- Fix off-by-one bug when testing size of ethernet packets. Thanks to
  Marty Leisner ([e-mail])

- Add a local autoconf macro to check for routines in libraries; the
  autoconf version is broken (it only puts the library name in the
  cache variable name). Thanks to John Hawkinson.

- Add a local autoconf macro to check for types; the autoconf version
  is broken (it uses grep instead of actually compiling a code fragment).

- Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header
  formats.

- Extend OSF ip header workaround to versions 1 and 2.

- Fix some signed problems in the nfs printer. As reported by David
  Sacerdote ([e-mail])

- Detect group wheel and use it as the default since BSD/OS' install
  can't hack numeric groups. Reported by David Sacerdote.

- AIX needs special loader options. Thanks to Jonathan I. Kamens
  ([e-mail])

- Fixed the nfs printer to print port numbers in decimal. Thanks to
  Kent Vander Velden ([e-mail])

- Find installed libpcap in /usr/local/lib when not using gcc.

- Disallow network masks with non-network bits set.

- Attempt to detect "egcs" versions of gcc.

- Add missing closing double quotes when displaying bootp strings.
  Reported by Viet-Trung Luu ([e-mail])

v3.3 Sat Nov 30 20:56:27 PST 1996

- Added Linux support.

- GRE encapsulated packet printer thanks to John Hawkinson
  ([e-mail])

- Rewrite gmt2local() to avoid problematic os dependencies.

- Suppress nfs truncation message on errors.

- Add missing m4 quoting in AC_LBL_UNALIGNED_ACCESS autoconf macro.
  Reported by Joachim Ott ([e-mail])

- Enable "ip_hl vs. ip_vhl" workaround for OSF4 too.

- Print arp hardware type in host order. Thanks to Onno van der Linden
  ([e-mail])

- Avoid solaris compiler warnings. Thanks to Bruce Barnett
  ([e-mail])

- Fix rip printer to not print one more route than is actually in the
  packet. Thanks to Jean-Luc Richier ([e-mail]) and
  Bill Fenner ([e-mail])

- Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.

- Fix dvmrp printer truncation checks and add a dvmrp probe printer.
  Thanks to Danny J. Mitzel ([e-mail])

- Rewrite ospf printer to improve truncation checks.

- Don't parse tcp options past the EOL. As noted by David Sacerdote
  ([e-mail]). Also, check tcp options to make sure they ar
  actually in the tcp header (in addition to the normal truncation
  checks). Fix the SACK code to print the N blocks (instead of the
  first block N times).

- Don't say really small UDP packets are truncated just because they
  aren't big enough to be a RPC. As noted by David Sacerdote.

- Added rfc1716 icmp codes as suggested by Martin Fredriksson
  ([e-mail])

  Thanks to John Hawkinson.

- Avoid infinite loop in tcp options printing code. Thanks to Jeffrey
  Mogul ([e-mail])

- Avoid using -lsocket in IRIX 5.2 and earlier since it breaks snoop.
  Thanks to John Hawkinson.

- Added some more packet truncation checks.

- On systems that have it, use sigset() instead of signal() since
  signal() has different semantics on these systems.

- Add code to massage unprintable characters in the domain and ipx
  printers. Thanks to John Hawkinson.

- Added explicit netmask support. Thanks to Steve Nuchia
  ([e-mail])

  Resulted from a suggestion from John Hawkinson ([e-mail]). Also
  fixed an endian bug when printing mx record and added some new record
  types.

- Added RIP V2 support. Thanks to Jeffrey Honig ([e-mail])

- Added T/TCP options printing. As suggested by Richard Stevens
  ([e-mail])

- Use autoconf to detect architectures that can't handle misaligned
  accesses.

v3.1 Thu Jun 13 20:59:32 PDT 1996
