324	  attempt to open it in Monitor mode
325	Add support for snapshot length for USB Memory-Mapped Interface
326	Fix configure and build on recent Linux kernels
327	Fix memory-mapped Linux capture to support pcap_next() and

502Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release
503
504	New Linux libpcap implementation, which, in 2.2 and later
505	kernels, uses PF_PACKET sockets and supports kernel packet
506	filtering (if compiled into the kernel), and supports the "any"
507	device for capturing on all interfaces.  Cleans up promiscuous
508	mode better on pre-2.2 kernels, and has various other fixes
509	(handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
510	doesn't show duplicate packets on loopback interface, etc.).
511
512	Fixed HP-UX libpcap implementation to correctly get the PPA for
513	an interface, to allow interfaces to be opened by interface name.
514
515	libpcap savefiles have system-independent link-layer type values
516	in the header, rather than sometimes platform-dependent DLT_
517	values, to make it easier to exchange capture files between
518	different OSes.
519
520	Non-standard capture files produced by some Linux tcpdumps, e.g.
521	the one from Red Hat Linux 6.2 and later, can now be read.
522
523	Updated autoconf stock files.
524
525	Filter expressions can filter on VLAN IDs and various OSI
526	protocols, and work on Token Ring (with non-source-routed
527	packets).
528
529	"pcap_open_dead()" added to allow compiling filter expressions
530	to pcap code without opening a capture device or capture file.
531
532	Header files fixed to allow use in C++ programs.
533
534	Removed dependancy on native headers for packet layout.
535	Removed Linux specific headers that were shipped.
536
537	Security fixes: Strcpy replaced with strlcpy, sprintf replaced
538	with snprintf.
539
540	Fixed bug that could cause subsequent "pcap_compile()"s to fail
541	erroneously after one compile failed.
542
543	Assorted other bug fixes.
544
545	README.aix and README.linux files added to describe
546	platform-specific issues.
547
548	"getifaddrs()" rather than SIOCGIFCONF used, if available.

559Assar Westerlund  <assar@sics.se>
560- Building outside the source code tree fixed.

564- Changed "pcap_lookupdev()" to dynamically grow the buffer into which
565  the list of interfaces is read as necessary in order to hold the
566  entire list.
567
568Greg Troxel <gdt@ir.bbn.com>
569- Added a new "pcap_compile_nopcap()", which lets you compile a filter

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

640  timeouts.
641
642- Changed ISLOOPBACK() macro when IFF_LOOPBACK isn't available to check

644  apparently call the loopback "lo" instead of "lo0").
645
646- Fixed Linux networking include files to use ints instead of longs to
647  avoid problems with 64 bit longs on the alpha. Thanks to Cristian

786  IRIX 5. Thanks to J. Eric Townsend (jet@abulafia.genmagic.com).
787
788- Hack around deficiency in Ultrix's make.
789
790- Fix two bugs related to the Solaris pre-5.3.2 bufmod bug; handle
791  savefiles that have more than snapshot bytes of data in them (so we
792  can read old savefiles) and avoid writing such files.
793
794- Added checkioctl which is used with gcc to check that the
795  "fixincludes" script has been run.
796
797v0.0.3 Tue Oct 18 18:13:46 PDT 1994
798
