3Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release
4
5	New Linux libpcap implementation, which, in 2.2 and later
6	kernels, uses PF_PACKET sockets and supports kernel packet
7	filtering (if compiled into the kernel), and supports the "any"
8	device for capturing on all interfaces.  Cleans up promiscuous
9	mode better on pre-2.2 kernels, and has various other fixes
10	(handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
11	doesn't show duplicate packets on loopback interface, etc.).
12
13	Fixed HP-UX libpcap implementation to correctly get the PPA for
14	an interface, to allow interfaces to be opened by interface name.
15
16	libpcap savefiles have system-independent link-layer type values
17	in the header, rather than sometimes platform-dependent DLT_
18	values, to make it easier to exchange capture files between
19	different OSes.
20
21	Non-standard capture files produced by some Linux tcpdumps, e.g.
22	the one from Red Hat Linux 6.2 and later, can now be read.
23
24	Updated autoconf stock files.
25
26	Filter expressions can filter on VLAN IDs and various OSI
27	protocols, and work on Token Ring (with non-source-routed
28	packets).
29
30	"pcap_open_dead()" added to allow compiling filter expressions
31	to pcap code without opening a capture device or capture file.
32
33	Header files fixed to allow use in C++ programs.
34
35	Removed dependancy on native headers for packet layout.
36	Removed Linux specific headers that were shipped.
37
38	Security fixes: Strcpy replaced with strlcpy, sprintf replaced
39	with snprintf.
40
41	Fixed bug that could cause subsequent "pcap_compile()"s to fail
42	erroneously after one compile failed.
43
44	Assorted other bug fixes.
45
46	README.aix and README.linux files added to describe
47	platform-specific issues.
48
49	"getifaddrs()" rather than SIOCGIFCONF used, if available.

51v0.5 Sat Jun 10 11:09:15 PDT 2000
52
53itojun@iijlab.net
54- Brought in KAME IPv6/IPsec bpf compiler.
55- Fixes for NetBSD.
56- Support added for OpenBSD DLT_LOOP and BSD/OS DLT_C_HDLC (Cisco HDLC),
57  and changes to work around different BSDs having different DLT_ types
58  with the same numeric value.
59
60Assar Westerlund  <assar@sics.se>
61- Building outside the source code tree fixed.
62- Changed to write out time stamps with 32-bit seconds and microseconds
63  fields, regardless of whether those fields are 32 bits or 64 bits in
64  the OS's native "struct timeval".
65- Changed "pcap_lookupdev()" to dynamically grow the buffer into which
66  the list of interfaces is read as necessary in order to hold the
67  entire list.
68
69Greg Troxel <gdt@ir.bbn.com>
70- Added a new "pcap_compile_nopcap()", which lets you compile a filter
71  expression into a BPF program without having an open live capture or
72  capture file.
73
74v0.4 Sat Jul 25 12:40:09 PDT 1998
75
76- Fix endian problem with DLT_NULL devices. From FreeBSD via Bill

80  dumps under Solaris.
81
82- Added configure options to disable flex and bison. Resulted from a
83  bug report by barnett@grymoire.crd.ge.com (Bruce Barnett). Also added
84  options to disable gcc and to force a particular packet capture type.
85
86- Added support for Fore ATM interfaces (qaa and fa) under IRIX. Thanks
87  to John Hawkinson (jhawk@mit.edu)
88
89- Change Linux PPP and SLIP to use DLT_RAW since the kernel does not
90  supply any "link layer" data.
91
92- Change Linux to use SIOCGIFHWADDR ioctl to determine link layer type.
93  Thanks to Thomas Sailer (sailer@ife.ee.ethz.ch)
94
95- Change IRIX PPP to use DLT_RAW since the kernel does not supply any
96  "link layer" data.
97
98- Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header
99  formats.
100
101- Added some new SGI snoop interface types. Thanks to Steve Alexander
102  (sca@refugee.engr.sgi.com)
103

105  Richard Allen (ra@hp.is) and Steinar Haug (sthaug@nethelp.no)
106
107- Fddi supports broadcast as reported by Jeff Macdonald
108  (jeff@iacnet.com). Also correct ieee802 and arcnet.
109

111  big enough for some interface types (e.g. FDDI). Thanks to Jes
112  Sorensen (Jes.Sorensen@cern.ch)
113
114- Fix some linux alignment problems.
115
116- Document promisc argument to pcap_open_live(). Reported by Ian Marsh
117  (ianm@sics.se)
118
119- Support Metricom radio packets under Linux. Thanks to Kevin Lai
120  (laik@gunpowder.stanford.edu)
121
122- Bind to interface name under Linux to avoid packets from multiple
123  interfaces on multi-homed hosts. Thanks to Kevin Lai
124  (laik@gunpowder.stanford.edu)
125

140- Fixed bug in pcap_dispatch() that kept it from returning on packet
141  timeouts.
142
143- Changed ISLOOPBACK() macro when IFF_LOOPBACK isn't available to check
144  for "lo" followed by an eos or digit (newer versions of Linux
145  apparently call the loopback "lo" instead of "lo0").
146
147- Fixed Linux networking include files to use ints instead of longs to
148  avoid problems with 64 bit longs on the alpha. Thanks to Cristian
149  Gafton (gafton@redhat.com)

244  don't support live package capture. This feature resulting from a
245  request from Jan van Oorschot (j.p.m.voorschot@et.tudelft.nl).
246

265  Bertilson (scott@unet.umn.edu).
266
267- Declare sys_errlist "const char *const" to avoid problems under
268  FreeBSD. Resulted from report by jher@eden.com.
269

271
272- Add missing variable declaration missing from 0.0.6
273
274v0.0.5 Fri Apr 28 00:22:21 PDT 1995
275
276- Workaround for problems when pcap_read() returns 0 due to the timeout
277  expiring.
278
279v0.0.4 Thu Apr 20 20:41:48 PDT 1995
280
281- Change configuration to not use gcc v2 flags with gcc v1.
282
283- Fixed a bug in pcap_next(); if pcap_dispatch() returns 0, pcap_next()
284  should also return 0. Thanks to Richard Stevens (rstevens@noao.edu).
285
286- Fixed configure to test for snoop before dlpi to avoid problems under
287  IRIX 5. Thanks to J. Eric Townsend (jet@abulafia.genmagic.com).
288
289- Hack around deficiency in Ultrix's make.
290
291- Fix two bugs related to the Solaris pre-5.3.2 bufmod bug; handle
292  savefiles that have more than snapshot bytes of data in them (so we
293  can read old savefiles) and avoid writing such files.
294
295- Added checkioctl which is used with gcc to check that the
296  "fixincludes" script has been run.
297
298v0.0.3 Tue Oct 18 18:13:46 PDT 1994
299

314  wasn't being initialized sometimes resulting in an "NIOCSFLAGS:
315  Invalid argument" error under OSF/1. Reported by Matt Day
316  (mday@artisoft.com) and Danny Mitzel (dmitzel@whitney.hitc.com).
317
