390	Check for valid port numbers (fit in a 16-bit unsigned field) in
391	  "port" filters
392	Reject attempts to put savefiles into non-blocking mode
393	Check for "no such device" for the "get the media types" ioctl
394	  in *BSD
395	Improve error messages from bpf_open(), and let it do the error
396	  handling

420	Update Endace DAG and ERF support
421	Add support for shared libraries on Solaris, HP-UX, and AIX
422	Build, install, and un-install shared libraries by default;
423	  don't build/install shared libraries on platforms we don't support
424	Fix building from a directory other than the source directory
425	Fix compiler warnings and builds on some platforms
426	Update config.guess and config.sub
427	Support monitor mode on mac80211 devices on Linux
428	Fix USB memory-mapped capturing on Linux; it requires a new DLT_
429	  value
430	On Linux, scan /sys/class/net for devices if we have it; scan
431	  it, or /proc/net/dev if we don't have /sys/class/net, even if
432	  we have getifaddrs(), as it'll find interfaces with no
433	  addresses

435	Fix BPF driver-loading error handling on AIX
436	Support getting the full-length interface description on FreeBSD

444	  errors, and check for the errors in question.
445	Note that poll() works on BPF devices is Snow Leopard
446	If an ENXIO or ENETDOWN is received, it may mean the device has
447	  gone away.  Deal with it.
448	For BPF, raise the default capture buffer size to from 32k to 512k
449	Support ps_ifdrop on Linux
450	Added a bunch of #ifdef directives to make wpcap.dll (WinPcap) compile

475	  attempt to open it in Monitor mode
476	Add support for snapshot length for USB Memory-Mapped Interface
477	Fix configure and build on recent Linux kernels
478	Fix memory-mapped Linux capture to support pcap_next() and

653Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release
654
655	New Linux libpcap implementation, which, in 2.2 and later
656	kernels, uses PF_PACKET sockets and supports kernel packet
657	filtering (if compiled into the kernel), and supports the "any"
658	device for capturing on all interfaces.  Cleans up promiscuous
659	mode better on pre-2.2 kernels, and has various other fixes
660	(handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
661	doesn't show duplicate packets on loopback interface, etc.).
662
663	Fixed HP-UX libpcap implementation to correctly get the PPA for
664	an interface, to allow interfaces to be opened by interface name.
665
666	libpcap savefiles have system-independent link-layer type values
667	in the header, rather than sometimes platform-dependent DLT_
668	values, to make it easier to exchange capture files between
669	different OSes.
670
671	Non-standard capture files produced by some Linux tcpdumps, e.g.
672	the one from Red Hat Linux 6.2 and later, can now be read.
673
674	Updated autoconf stock files.
675
676	Filter expressions can filter on VLAN IDs and various OSI
677	protocols, and work on Token Ring (with non-source-routed
678	packets).
679
680	"pcap_open_dead()" added to allow compiling filter expressions
681	to pcap code without opening a capture device or capture file.
682
683	Header files fixed to allow use in C++ programs.
684
685	Removed dependancy on native headers for packet layout.
686	Removed Linux specific headers that were shipped.
687
688	Security fixes: Strcpy replaced with strlcpy, sprintf replaced
689	with snprintf.
690
691	Fixed bug that could cause subsequent "pcap_compile()"s to fail
692	erroneously after one compile failed.
693
694	Assorted other bug fixes.
695
696	README.aix and README.linux files added to describe
697	platform-specific issues.
698
699	"getifaddrs()" rather than SIOCGIFCONF used, if available.

716  the list of interfaces is read as necessary in order to hold the
717  entire list.
718
719Greg Troxel <gdt@ir.bbn.com>

743  Thanks to Thomas Sailer (sailer@ife.ee.ethz.ch)

749  formats.
750

791  timeouts.
792
793- Changed ISLOOPBACK() macro when IFF_LOOPBACK isn't available to check
794  for "lo" followed by an eos or digit (newer versions of Linux
795  apparently call the loopback "lo" instead of "lo0").
796
797- Fixed Linux networking include files to use ints instead of longs to
798  avoid problems with 64 bit longs on the alpha. Thanks to Cristian
799  Gafton (gafton@redhat.com)

927  expiring.
928
929v0.0.4 Thu Apr 20 20:41:48 PDT 1995
930
931- Change configuration to not use gcc v2 flags with gcc v1.
932
933- Fixed a bug in pcap_next(); if pcap_dispatch() returns 0, pcap_next()
934  should also return 0. Thanks to Richard Stevens (rstevens@noao.edu).
935
936- Fixed configure to test for snoop before dlpi to avoid problems under
937  IRIX 5. Thanks to J. Eric Townsend (jet@abulafia.genmagic.com).
938
939- Hack around deficiency in Ultrix's make.
940
941- Fix two bugs related to the Solaris pre-5.3.2 bufmod bug; handle
942  savefiles that have more than snapshot bytes of data in them (so we
943  can read old savefiles) and avoid writing such files.
944
945- Added checkioctl which is used with gcc to check that the
946  "fixincludes" script has been run.
947
948v0.0.3 Tue Oct 18 18:13:46 PDT 1994

965  Invalid argument" error under OSF/1. Reported by Matt Day
966  (mday@artisoft.com) and Danny Mitzel (dmitzel@whitney.hitc.com).
