@(#) $Header: /tcpdump/master/libpcap/CHANGES,v 1.56 2001-10-23 04:37:31 mcr Exp $ (LBL)

Monday October 23, 2001. mcr@sandelman.ottawa.on.ca. Summary for 0.7 release

	Added pcap_findalldevs() call to get list of interfaces in a MI way.

	pcap_stats() has been documented as to what its counters mean on 
	each platform.

Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release

	New Linux libpcap implementation, which, in 2.2 and later
	kernels, uses PF_PACKET sockets and supports kernel packet
	filtering (if compiled into the kernel), and supports the "any"
	device for capturing on all interfaces.  Cleans up promiscuous
	mode better on pre-2.2 kernels, and has various other fixes
	(handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
	doesn't show duplicate packets on loopback interface, etc.).

	Fixed HP-UX libpcap implementation to correctly get the PPA for
	an interface, to allow interfaces to be opened by interface name.

	libpcap savefiles have system-independent link-layer type values
	in the header, rather than sometimes platform-dependent DLT_
	values, to make it easier to exchange capture files between
	different OSes.

	Non-standard capture files produced by some Linux tcpdumps, e.g.
	the one from Red Hat Linux 6.2 and later, can now be read.

	Updated autoconf stock files.

	Filter expressions can filter on VLAN IDs and various OSI
	protocols, and work on Token Ring (with non-source-routed
	packets).

	"pcap_open_dead()" added to allow compiling filter expressions
	to pcap code without opening a capture device or capture file.

	Header files fixed to allow use in C++ programs.

	Removed dependancy on native headers for packet layout.
	Removed Linux specific headers that were shipped.

	Security fixes: Strcpy replaced with strlcpy, sprintf replaced
	with snprintf.

	Fixed bug that could cause subsequent "pcap_compile()"s to fail
	erroneously after one compile failed.

	Assorted other bug fixes.

	README.aix and README.linux files added to describe
	platform-specific issues.

	"getifaddrs()" rather than SIOCGIFCONF used, if available.

v0.5 Sat Jun 10 11:09:15 PDT 2000

itojun@iijlab.net
- Brought in KAME IPv6/IPsec bpf compiler.
- Fixes for NetBSD.
- Support added for OpenBSD DLT_LOOP and BSD/OS DLT_C_HDLC (Cisco HDLC),
  and changes to work around different BSDs having different DLT_ types
  with the same numeric value.

Assar Westerlund  <assar@sics.se>
- Building outside the source code tree fixed.
- Changed to write out time stamps with 32-bit seconds and microseconds
  fields, regardless of whether those fields are 32 bits or 64 bits in
  the OS's native "struct timeval".
- Changed "pcap_lookupdev()" to dynamically grow the buffer into which
  the list of interfaces is read as necessary in order to hold the
  entire list.

Greg Troxel <gdt@ir.bbn.com>
- Added a new "pcap_compile_nopcap()", which lets you compile a filter
  expression into a BPF program without having an open live capture or
  capture file.
  
v0.4 Sat Jul 25 12:40:09 PDT 1998

- Fix endian problem with DLT_NULL devices. From FreeBSD via Bill
  Fenner (fenner@parc.xerox.com)

- Fix alignment problem with FDDI under DLPI. This was causing core
  dumps under Solaris.

  bug report by barnett@grymoire.crd.ge.com (Bruce Barnett). Also added
  options to disable gcc and to force a particular packet capture type.

- Added support for Fore ATM interfaces (qaa and fa) under IRIX. Thanks
  to John Hawkinson (jhawk@mit.edu)

- Change Linux PPP and SLIP to use DLT_RAW since the kernel does not
  supply any "link layer" data.

- Change Linux to use SIOCGIFHWADDR ioctl to determine link layer type.
  Thanks to Thomas Sailer (sailer@ife.ee.ethz.ch)

- Change IRIX PPP to use DLT_RAW since the kernel does not supply any
  "link layer" data.

  formats.

- Added some new SGI snoop interface types. Thanks to Steve Alexander
  (sca@refugee.engr.sgi.com)

- Fixes for HP-UX 10.20 (which is similar to HP-UX 9). Thanks to
  Richard Allen (ra@hp.is) and Steinar Haug (sthaug@nethelp.no)

- Fddi supports broadcast as reported by Jeff Macdonald
  (jeff@iacnet.com). Also correct ieee802 and arcnet.

  big enough for some interface types (e.g. FDDI). Thanks to Jes
  Sorensen (Jes.Sorensen@cern.ch)

- Fix some linux alignment problems.

  Reported reported by Eric Jacksch (jacksch@tenebris.ca)

- Fixed bug in pcap_dispatch() that kept it from returning on packet
  timeouts.

- Changed ISLOOPBACK() macro when IFF_LOOPBACK isn't available to check
  for "lo" followed by an eos or digit (newer versions of Linux
  apparently call the loopback "lo" instead of "lo0").

- Fixed Linux networking include files to use ints instead of longs to
  avoid problems with 64 bit longs on the alpha. Thanks to Cristian
  Gafton (gafton@redhat.com)

v0.1 Fri Apr 28 18:11:03 PDT 1995

- Fixed compiler and optimizer bugs.  The BPF filter engine uses unsigned
  comparison operators, while the code generator and optimizer assumed
  signed semantics in several places.  Thanks to Charlie Slater
  (cslater@imatek.com) for pointing this out.

- Removed FDDI ifdef's, they aren't really needed. Resulted from report
  by Gary Veum (veum@boa.gsfc.nasa.gov).

- Workaround for problems when pcap_read() returns 0 due to the timeout
  expiring.

v0.0.4 Thu Apr 20 20:41:48 PDT 1995

- Change configuration to not use gcc v2 flags with gcc v1.

  IRIX 5. Thanks to J. Eric Townsend (jet@abulafia.genmagic.com).

- Hack around deficiency in Ultrix's make.

- Fix two bugs related to the Solaris pre-5.3.2 bufmod bug; handle

  "fixincludes" script has been run.

v0.0.3 Tue Oct 18 18:13:46 PDT 1994

- Fixed configure to test for snoop before dlpi to avoid problems under

  by Mahesh Jethanandani (mahesh@npix.com).

v0.0.1 Fri Jun 24 14:50:57 PDT 1994

- Fixed bug in nit_setflags() in pcap-snit.c. The streams ioctl timeout
  wasn't being initialized sometimes resulting in an "NIOCSFLAGS:
  Invalid argument" error under OSF/1. Reported by Matt Day
  (mday@artisoft.com) and Danny Mitzel (dmitzel@whitney.hitc.com).

- Turn on FDDI support by default.

v0.0 Mon Jun 20 19:20:16 PDT 1994

- Initial release.

- Fixed bug with greater/less keywords, reported by Mark Andrews
  (mandrews@alias.com).
