Source code:
Use __builtin_unreachable() in PCAP_UNREACHABLE.
Use AS_HELP_STRING macro instead of AC_HELP_STRING in the
configure scripts, to avoid deprecation warnings.
Change availability tags in pcap.h to make it easier to
arrange for it to be used in Darwin releases.
Use AS_HELP_STRING for --enable-remote.
Fix some formatting string issues found by cppcheck.
Various small code and comment cleanups.
Use PCAP_ERROR (defined as -1) rather than explicit -1 for
functions the documentation says return PCAP_ERROR.
Remove unused code from the filter compiler.
Use _declspec(deprecated(msg)) rather than __pragma(deprecated)
for Windows deprecation warnings, so the message that was
specified shows up.
diag-control.h: define PCAP_DO_PRAGMA() iff we're going to use it.
Use "%d" to print some signed ints.
Use the Wayback Machine for a removed document in a comment.
Add some const qualifiers.
RDMA: Use PRIu64 to print a uint64_t.
"Dead" pcap_ts from pcap_open_dead() and ..._with_tstamp_precision():
Don't crash if pcap_breakloop() is called.
Savefiles:
Fix pcap_dispatch() to return number of packets processed, rather
than 0, even at EOF.
If we get an error writing the packet header, don't write the
packet data.
Put PFLOG UID and PID values in the header into host byte order
when reading a LINKTYPE_PFLOG file.

transfers when reading savefiles.
Don't crash if pcap_can_set_rfmon() is called.
Fix pcap_offline_read() loop.

denied" errors.
SITA: Fix a typo in a variable name.
Packet filtering:
Get PFLOG header length from the length value in the header.

#1051).
Fix double-free crashes on errors such as running on a kernel with
CONFIG_PACKET_MMAP not configured (issue #1054).

BPF capture (*BSD, macOS, AIX, Solaris 11):
Fix case where a device open might fail, rather than falling back
to a smaller buffer size, when the initial buffer size is too
big.

platform with C++ code, and make sure they generate code for
the same instruction set bit-width (both 32-bit or both 64-bit)

README.linux.md isn't Markdown, rename it just README.linux.
pcapng:
Support reading version 1.2, which some writers produce, and which
is the same as 1.0 (some new block types were added, but
that's not sufficient reason to bump the minor version number,
as code that understands those new block types can handle them
in a 1.0 file)
Linux:
Drop support for text-mode USB captures, as we require a 2.6.27
or later kernel (credit to Chaoyuan Peng for noting the
sscanf vulnerabilities in the text-mode code that got me to
realize that we didn't need this code any more)
Bluetooth: fix non-blocking mode.
Don't assume that all compilers used to build for Linux support
the __atomic builtins
Windows:
Add more information in "interface disappeared" error messages, in
the hopes of trying to figure out the cause.

Indicate in the error message which "device was removed" error
occurred.

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 dependency 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.

the list of interfaces is read as necessary in order to hold the
entire list.

- Fixed Linux include file problems when using GNU libc.
- Ifdef ARPHRD_FDDI since not all versions of the Linux kernel have it.
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

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).

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

(Pascal.Hennequin@hugo.int-evry.fr).

expiring.
v0.0.4 Thu Apr 20 20:41:48 PDT 1995
- Change configuration to not use gcc v2 flags with gcc v1.
- Fixed a bug in pcap_next(); if pcap_dispatch() returns 0, pcap_next()
should also return 0. Thanks to Richard Stevens (rstevens@noao.edu).
- Fixed configure to test for snoop before dlpi to avoid problems under
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
savefiles that have more than snapshot bytes of data in them (so we
can read old savefiles) and avoid writing such files.
- Added checkioctl which is used with gcc to check that the
"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
IRIX 5. Thanks to J. Eric Townsend (jet@abulafia.genmagic.com).

Stevens.
- Determine pcap link type from dlpi media type. Resulted from report
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.
