219	Note that poll() works on BPF devices is Snow Leopard
220	If an ENXIO or ENETDOWN is received, it may mean the device has
221	  gone away.  Deal with it.

249	  attempt to open it in Monitor mode
250	Add support for snapshot length for USB Memory-Mapped Interface
251	Fix configure and build on recent Linux kernels
252	Fix memory-mapped Linux capture to support pcap_next() and

422	Added pcap_findalldevs() call to get list of interfaces in a MI way.
423
424	pcap_stats() has been documented as to what its counters mean on
425	each platform.
426
427Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release
428
429	New Linux libpcap implementation, which, in 2.2 and later
430	kernels, uses PF_PACKET sockets and supports kernel packet
431	filtering (if compiled into the kernel), and supports the "any"
432	device for capturing on all interfaces.  Cleans up promiscuous
433	mode better on pre-2.2 kernels, and has various other fixes
434	(handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
435	doesn't show duplicate packets on loopback interface, etc.).
436
437	Fixed HP-UX libpcap implementation to correctly get the PPA for
438	an interface, to allow interfaces to be opened by interface name.
439
440	libpcap savefiles have system-independent link-layer type values
441	in the header, rather than sometimes platform-dependent DLT_
442	values, to make it easier to exchange capture files between
443	different OSes.
444
445	Non-standard capture files produced by some Linux tcpdumps, e.g.
446	the one from Red Hat Linux 6.2 and later, can now be read.
447
448	Updated autoconf stock files.
449
450	Filter expressions can filter on VLAN IDs and various OSI
451	protocols, and work on Token Ring (with non-source-routed
452	packets).
453
454	"pcap_open_dead()" added to allow compiling filter expressions
455	to pcap code without opening a capture device or capture file.
456
457	Header files fixed to allow use in C++ programs.
458
459	Removed dependancy on native headers for packet layout.
460	Removed Linux specific headers that were shipped.
461
462	Security fixes: Strcpy replaced with strlcpy, sprintf replaced
463	with snprintf.
464
465	Fixed bug that could cause subsequent "pcap_compile()"s to fail
466	erroneously after one compile failed.
467
468	Assorted other bug fixes.
469
470	README.aix and README.linux files added to describe
471	platform-specific issues.
472
473	"getifaddrs()" rather than SIOCGIFCONF used, if available.

476
477itojun@iijlab.net
478- Brought in KAME IPv6/IPsec bpf compiler.
479- Fixes for NetBSD.
480- Support added for OpenBSD DLT_LOOP and BSD/OS DLT_C_HDLC (Cisco HDLC),
481  and changes to work around different BSDs having different DLT_ types
482  with the same numeric value.
483
484Assar Westerlund  <assar@sics.se>
485- Building outside the source code tree fixed.
486- Changed to write out time stamps with 32-bit seconds and microseconds
487  fields, regardless of whether those fields are 32 bits or 64 bits in
488  the OS's native "struct timeval".
489- Changed "pcap_lookupdev()" to dynamically grow the buffer into which
490  the list of interfaces is read as necessary in order to hold the
491  entire list.
492
493Greg Troxel <gdt@ir.bbn.com>
494- Added a new "pcap_compile_nopcap()", which lets you compile a filter
495  expression into a BPF program without having an open live capture or
496  capture file.
497

511  to John Hawkinson (jhawk@mit.edu)
512
513- Change Linux PPP and SLIP to use DLT_RAW since the kernel does not
514  supply any "link layer" data.
515
516- Change Linux to use SIOCGIFHWADDR ioctl to determine link layer type.
517  Thanks to Thomas Sailer (sailer@ife.ee.ethz.ch)
518
519- Change IRIX PPP to use DLT_RAW since the kernel does not supply any
520  "link layer" data.
521
522- Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header
523  formats.
524

529  Richard Allen (ra@hp.is) and Steinar Haug (sthaug@nethelp.no)
530
531- Fddi supports broadcast as reported by Jeff Macdonald
532  (jeff@iacnet.com). Also correct ieee802 and arcnet.

537
538- Fix some linux alignment problems.
539

565  timeouts.
566
567- Changed ISLOOPBACK() macro when IFF_LOOPBACK isn't available to check
568  for "lo" followed by an eos or digit (newer versions of Linux
569  apparently call the loopback "lo" instead of "lo0").
570
571- Fixed Linux networking include files to use ints instead of longs to
572  avoid problems with 64 bit longs on the alpha. Thanks to Cristian
573  Gafton (gafton@redhat.com)

659- Fixed compiler and optimizer bugs.  The BPF filter engine uses unsigned
660  comparison operators, while the code generator and optimizer assumed
661  signed semantics in several places.  Thanks to Charlie Slater
662  (cslater@imatek.com) for pointing this out.
663

665  by Gary Veum (veum@boa.gsfc.nasa.gov).
666

689  Bertilson (scott@unet.umn.edu).
690

695
696- Add missing variable declaration missing from 0.0.6
697
698v0.0.5 Fri Apr 28 00:22:21 PDT 1995

704
705- Change configuration to not use gcc v2 flags with gcc v1.
706
707- Fixed a bug in pcap_next(); if pcap_dispatch() returns 0, pcap_next()

709
710- Fixed configure to test for snoop before dlpi to avoid problems under
711  IRIX 5. Thanks to J. Eric Townsend (jet@abulafia.genmagic.com).
712
713- Hack around deficiency in Ultrix's make.
714
715- Fix two bugs related to the Solaris pre-5.3.2 bufmod bug; handle
716  savefiles that have more than snapshot bytes of data in them (so we
717  can read old savefiles) and avoid writing such files.
718
719- Added checkioctl which is used with gcc to check that the
720  "fixincludes" script has been run.
721
722v0.0.3 Tue Oct 18 18:13:46 PDT 1994
723
724- Fixed configure to test for snoop before dlpi to avoid problems under
725  IRIX 5. Thanks to J. Eric Townsend (jet@abulafia.genmagic.com).

738  wasn't being initialized sometimes resulting in an "NIOCSFLAGS:
739  Invalid argument" error under OSF/1. Reported by Matt Day
740  (mday@artisoft.com) and Danny Mitzel (dmitzel@whitney.hitc.com).
741
742- Turn on FDDI support by default.
