14        warnings.
15      Clean up code that computes the length of a netmask.

118      Squelch compiler warning in grammar.c.
119      Fix findalldevtest compilation if IPv6 isn't enabled.
120      Rename helper routines for pcap modules to have names beginning with
121        pcapint_, to avoid namespace collisions for code linking statically
122        with libpcap.
123      Avoid casting hack for the Windows cleanup-on-exit routine.
124      Use %zu format for one case of printing a size_t.

136        isn't empty).
137      Optimizer fix from Archit Shah to mark value as unknown when store
138        of that value is deleted (#972); fixes #143, #434, #436, #437,
139        and #1076.

160    macOS:
161      Redid the availability macros to be closer to what Apple's doing
162        in recent SDKs, including tagging pcap-namedb.h routines.
163      Fix the install name of the installed shared library to have a
164        full path when building with CMake.

180      Work around a bug in Npcap 1.00 in case of driver version mismatch.
181      Don't call WSACleanup() when handling a failed WSAStartup().
182    BSD, macOS, AIX, Solaris 11, Linux:
183      Add a new error PCAP_ERROR_CAPTURE_NOTSUP, for use if a capture
184        mechanism is not present, in the hopes that, for example,
185        attempts to capture on Windows Services for Linux 1, in which
186        the NT kernel attempts to simulate Linux system calls but does
187        not support packet sockets, can get an error that better
188        indicates the underlying problem.

197        double frees in some cases.
198      Don't define SOCKET ourselves; instead, define PCAP_SOCKET as int
199        on UN*Xes and as SOCKET on Windows.
200      CVE-2024-8006: Fix pcap_findalldevs_ex() not to crash if passed a
201        file:// URL with a path to a directory that cannot be opened.
202    Savefiles:
203      Handle DLT_/LINKTYPE_ mapping better, to handle some
204        OpenBSD-specific link types better.
205      Treat if_tsoffset as signed in pcapng files, as the spec says.
206      Don't try to fix the "real" length for isochronous USB
207        transfers if the number of USB descriptors is too large.
208      Reject pcap files where one of the reserved fields in the
209        "link-layer type plus other stuff" is non-zero.
210    Building and testing:
211      Add a configure option to help debugging (--enable-instrument-functions).
212      Improved tests and error reporting for uses of pkg-config, and
213        improve help message.
214      Fix Haiku build.
215      With CMake, install headers in CMAKE_INSTALL_INCLUDEDIR rather
216        than just include.
217      Build libpcap.a before building test programs.
218      Print address family numerically, as well as symbolically,
219        in findalldevstest.
220      Fail with suggestions, rather than failing over to no capture
221        support, if no capture mechanism was found.  Fixes issue #1016.
222      Don't indent comments in Make, as that may cause them not to be
223        recognized as comments.
224      Don't check for libssl if we aren't going to use it.
225      Better handle enabling and disabling of sanitizers.  Fixes issue
226        #1171.

239        devel mode if supported.
240      Don't ignore spaces between CMAKE_C_FLAGS and DPDK_C_FLAGS with
241        CMake.
242      Use noreturn and __format__ with XL C 7.0 and later.
243      Check for the same -W flags in autotools and CMake.
244      Autoconf: Add autogen.sh, remove configure and config.h.in and put
245        these generated files in the release tarball.
246      Autoconf: Get the size of a time_t.

252      Add initial support for building with TinyCC.
253      Address all known compiler warnings specific to illumos, Linux, NetBSD,

302    Source code:
303      Use __builtin_unreachable() in PCAP_UNREACHABLE.
304      Use AS_HELP_STRING macro instead of AC_HELP_STRING in the
305        configure scripts, to avoid deprecation warnings.
306      Change availability tags in pcap.h to make it easier to
307        arrange for it to be used in Darwin releases.
308      Use AS_HELP_STRING for --enable-remote.
309      Fix some formatting string issues found by cppcheck.
310      Various small code and comment cleanups.
311      Use PCAP_ERROR (defined as -1) rather than explicit -1 for
312        functions the documentation says return PCAP_ERROR.
313      Remove unused code from the filter compiler.
314      Use _declspec(deprecated(msg)) rather than __pragma(deprecated)
315        for Windows deprecation warnings, so the message that was
316        specified shows up.
317      diag-control.h: define PCAP_DO_PRAGMA() iff we're going to use it.
318      Use "%d" to print some signed ints.
319      Use the Wayback Machine for a removed document in a comment.
320      Add some const qualifiers.
321      RDMA: Use PRIu64 to print a uint64_t.
322    "Dead" pcap_ts from pcap_open_dead() and ..._with_tstamp_precision():
323        Don't crash if pcap_breakloop() is called.
324    Savefiles:
325      Fix pcap_dispatch() to return number of packets processed, rather
326        than 0, even at EOF.
327      If we get an error writing the packet header, don't write the
328        packet data.
329      Put PFLOG UID and PID values in the header into host byte order
330        when reading a LINKTYPE_PFLOG file.
331      Put CAN ID field in CAN pseudo-headers for LINUX_SLL2, as we do

337    Capture:
338      Never process more than INT_MAX packets in a pcap_dispatch() call,
339        to avoid integer overflow (issue #1087).
340      Improve error messages for "no such device" and "permission
341        denied" errors.
342      SITA: Fix a typo in a variable name.
343    Packet filtering:
344      Get PFLOG header length from the length value in the header.
345      Support all the direction, reason, and action types supported by
346        all systems that support PFLOG.
347      Don't require PFLOG support on the target machine in order to
348        support PFLOG filtering (also fixes issue #1076).
349      Expand abbreviations into "proto X" properly.
350      gencode.c: Update a comment about the VLAN TPID test.

367      Always turn on PACKET_AUXDATA (see issue #1105).
368      We require 2.6.27 or later, so PACKET_RESERVE is available.
369      Make sure there's reserved space for a DLT_LINUX_SLL2 header
370        when capturing.
371      Correctly compute the "real" length for isochronous USB transfers.
372      Don't have an eventfd descriptor open in non-blocking mode, so as
373        not to waste descriptors.
374      netfilter: Squelch a narrowing warning (To be look at before 2038).
375    BPF capture (*BSD, macOS, AIX, Solaris 11):
376      Fix case where a device open might fail, rather than falling back
377        to a smaller buffer size, when the initial buffer size is too
378        big.
379      Use an unsigned device number to iterate over BPF devices, to
380        squelch a compiler warning.
381    NetBSD:
382      Fix handling of LINKTYPE_HDLC/DLT_HDLC.
383    rpcap:
384      Fix unaligned accesses in rpcapd (pull request #1037).

397        order.
398      Suppress temporarily the warnings with "enable remote packet capture".
399    Windows:
400      Add support for NdisMediumIP (pull request #1027).
401      Don't require applications using pcap to be built with VS 2015 or
402        later.
403      Use the correct string for the DLL VersionInfo.
404      Remove unnecessary DllMain() function.
405      Correctly handle ERROR_INVALID_FUNCTION from
406        PacketGetTimestampModes() (indicate that WinPcap or an older
407        version of Npcap is probably installed).
408      Fix use-after-free in some cases when a pcap_t is closed.
409      Make sure an error is returned by pcap_create_interface() if
410        PacketOpenAdapter() fails.
411      Return an error if the driver reports 0 timestamp modes supported.
412      Close the ADAPTER handle for some errors in
413        pcap_create_interface().
414      Get rid of old unmaintained VS project files.
415      Fix deprecation warning for pcap_handle().
416      Npcap is now at npcap.com, not npcap.org.
417      Make sure "no such device" and "no permission to open device"
418        errors show up in pcap_activate(), not pcap_create() (fixes,
419        among other things, tcpdump -i <interface-number>).
420      npcap: squelch deprecation warnings for kernel dump mode.
421    Haiku:
422      Implement pcap_lib_version(), as now required.
423      Handle negative or too-large snaplen values.
424      Fix various build issues and warnings.
425    Building and testing:

427      Update config.guess and config.sub.
428      If we look for an SSL library with pkg-config in configure script,
429        try pkg-config first.
430      If we have pkg-config and Homebrew, try to set pkg-config up to
431        find Homebrew packages.
432      Handle some Autoconf/make errors better.
433      Use "git archive" for the "make releasetar" process.
434      Remove the release candidate rcX targets.
435      Fix compiling on Solaris 9/SPARC and 11/AMD64.
436      Address assorted compiler warnings.

442      Give more details if check for usable (F)Lex fails.
443      Fix compiling with GCC 4.6.4.
444      Don't use add_compile_options() with CMake, as we currently don't
445        require 2.8.12, where it first appeared.
446      Don't provide -L/usr/lib for pkg-config --libs in pkg-config.
447      Fix error message for inadequate Bison/Berkeley YACC.
448      configure: correctly do some DPDK checks.
449      Only use pkg-config when checking for DPDK.
450      Allow the path in which DPDK is installed to be specified.
451      Use pkg-config first when checking for libibverbs.
452      CMake: fix check for libibverbs with Sun's C compiler.
453      Have CMake warn if no capture mechanism can be found.

455      Squelch some CMake warnings.
456      Fix diag-control.h to handle compiling with clang-cl (issues
457        #1101 and #1115).
458      Cleanup various leftover cruft in the configure script.
459      Fix building without protochain support. (GH #852)
460      Check for a usable YACC (or Bison) and {F}lex in CMake, as we do
461        in autotools.
462      Only check for a C++ compiler on Haiku, as that's the only
463        platform with C++ code, and make sure they generate code for
464        the same instruction set bit-width (both 32-bit or both 64-bit)
465        (issue #1112).
466      On Solaris, check the target bit-width and set PKG_CONFIG_PATH
467        appropriately, to handle the mess that is the D-Bus library
468        package (issue #1112).
469      Fix generation of pcap-config and libpcap.pc files (issue #1062).
470      pcap-config: don't assume the system library directory is /usr/lib.

477      Cirrus CI: Add the libssl-dev package in the Linux task.
478      Cirrus CI: Add the openssl@3 brew package in the macOS task.
479      Get "make shellcheck" to pass again.
480      CMake: Build valgrindtest only if Autoconf would.
481      CMake: use ${CMAKE_INSTALL_SBINDIR} rather than just sbin.
482      CMake: use NUL: as the null device on Windows.
483      autoconf: fix typo in test of macOS version.
484      Makefile.in: Add two missing files in EXTRA_DIST.

502      In pcap-filter(7) "domain" is an id.
503      Discuss backward compatibility in pcap-filter(7).
504      Other improvements to pcap-filter(7).
505      Document pcap_breakloop(3PCAP) interaction with threads better.
506      Document PCAP_ERROR_NOT_ACTIVATED for more routines.
507
508Wednesday, June 9, 2021:

510    Packet filtering:
511      Fix "type XXX subtype YYY" giving a parse error
512    Source code:
513      Add PCAP_AVAILABLE_1_11.
514    Building and testing:
515      Rename struct bpf_aux_data to avoid NetBSD compile errors
516      Squelch some compiler warnings
517      Squelch some Bison warnings
518      Fix cross-builds with older kernels lacking BPF_MOD and BPF_XOR
519      Fix Bison detection for minor version 0.
520      Fix parallel build with FreeBSD make.
521      Get DLT_MATCHING_MAX right in gencode.c on NetBSD.
522      Define timeradd() and timersub() if necessary.
523      Fix Cygwin/MSYS target directories.
524      Fix symlinking with DESTDIR.
525      Fix generation of libpcap.pc with CMake when not building a shared
526          library.
527      Check for Arm64 as well as x86-64 when looking for packet.lib on
528          Windows.
529    Documentation:
530      Refine Markdown in README.md.
531      Improve the description of portrange in filters.
532      README.linux.md isn't Markdown, rename it just README.linux.
533    pcapng:
534      Support reading version 1.2, which some writers produce, and which
535          is the same as 1.0 (some new block types were added, but
536          that's not sufficient reason to bump the minor version number,
537          as code that understands those new block types can handle them
538          in a 1.0 file)
539    Linux:
540      Drop support for text-mode USB captures, as we require a 2.6.27
541          or later kernel (credit to Chaoyuan Peng for noting the
542          sscanf vulnerabilities in the text-mode code that got me to
543          realize that we didn't need this code any more)
544      Bluetooth: fix non-blocking mode.
545      Don't assume that all compilers used to build for Linux support
546          the __atomic builtins
547    Windows:
548      Add more information in "interface disappeared" error messages, in
549        the hopes of trying to figure out the cause.
550      Treat ERROR_DEVICE_REMOVED as "device was removed".
551      Indicate in the error message which "device was removed" error
552          occurred.
553      Report the Windows error status if PacketSendPacket() fails.
554      Use %lu for ULONGs in error message formats.
555      Don't treat the inability to find airpcap.dll as an error.
556      Ignore spurious error reports by Microsoft Surface mobile
557          telephony modem driver
558    rpcap:
559      Clean up error checking and error messages for server address
560          lookup.
561
562Tuesday, December 29, 2020

567    Add pcap_datalink_val_to_description_or_dlt()
568    Handle the pcap private data in a fashion that makes fewer
569       assumptions about memory layouts (might fix GitHub issue #940
570       on ARM)
571    Fix some thread safety issues
572    pcap_findalldevs(): don't sort interfaces by unit number
573    Always return a list of supported time-stamp types, even if only
574        host time stamps are supported
575    Increase the maximum snaplen for LINKTYPE_USBPCAP/DLT_USBPCAP
576    Report the DLT description in error messages
577    Add pcap_init() for first-time initialization and global option
578        setting; it's not required, but may be used
579    Remove (unused) SITA support
580    Capture file reading:
581        Correctly handle pcapng captures with more than one IDB with a
582            snapshot length greater than the supported maximum
583    Capture file writing:
584        Create the file in pcap_dump_open_append() if it doesn't exist
585    Packet filtering:
586        Fix "unknown ether proto 'aarp'"
587        Add a new filter "ifindex" for DLT_LINUX_SLL2 files on all
588            platforms and live Linux captures

604        Support rpcap-over-TLS
605        Redo protocol version negotiation to avoid problems with old
606            servers (it still works with servers using the old negotiation,
607            as well as servers not supporting negotiation)
608        Error handling cleanups
609        Add some new authentication libpcap error codes for specific
610            errors
611        Fix some inetd issues in rpcapd
612        Fix rpcapd core dumps with invalid configuration file
613        On UN*X, don't have rpcapd tell the client why authentication
614            failed, so a brute-force attacker can't distinguish between
615            "unknown user name" and "known user name, wrong password"

627    Linux:
628        Require PF_PACKET support, and kernel 2.6.27 or later
629        Handle systems without AF_INET or AF_UNIX socket support
630        Get rid of Wireless Extensions for turning monitor mode on
631        Proper memory sync for PACKET_MMAP (may prevent GitHub issue
632            #898)
633        Drop support for libnl 1 and 2.
634        Return error on interface going away, but not if it just went
635            down but is still present
636        Set socket protocol only after packet ring configured,
637            reducing bogus packet drop reports
638        Get ifdrop stats from sysfs.
639        When adjusting BPF programs, do not subtract the
640            SLL[2]_HDR_LEN if the location is negative (special metadata
641            offset), to preserve references to metadata; see
642            https://github.com/the-tcpdump-group/tcpdump/issues/480#issuecomment-486827278
643        Report a warning for unknown ARPHRD types
644        Have pcap_breakloop() forcibly break out of a sleeping
645            capture loop
646        Add support for DSA data link types
647        For raw USB bus capture, use the snapshot length to set the
648            buffer size, and set the len field to reflect the length
649            in the URB (GitHub issue #808)
650        With a timeout of zero, wait indefinitely
651        Clean up support for some non-GNU libc C libraries
652        Add DLT_LINUX_SLL2 for cooked-mode captures
653        Probe CONFIGURATION descriptor of connected USB devices
654        Treat EPERM on ethtool ioctls as meaning "not supported", as
655            permissions checks are done before checking whether the
656            ioctl is supported at all
657    macOS:
658        Cope with getting EPWROFF from SIOCGIFMEDIA
659        Treat EPERM on SIOCGIFMEDIA as meaning "not supported", as

661            ioctl is supported at all
662        Treat ENXIO when reading packets as meaning "the interface
663            was removed"

1134	Update Endace DAG and ERF support
1135	Add support for shared libraries on Solaris, HP-UX, and AIX

1140	Update config.guess and config.sub
1141	Support monitor mode on mac80211 devices on Linux
1142	Fix USB memory-mapped capturing on Linux; it requires a new DLT_
1143	  value
1144	On Linux, scan /sys/class/net for devices if we have it; scan
1145	  it, or /proc/net/dev if we don't have /sys/class/net, even if
1146	  we have getifaddrs(), as it'll find interfaces with no
1147	  addresses

1158	  errors, and check for the errors in question.
1159	Note that poll() works on BPF devices is Snow Leopard
1160	If an ENXIO or ENETDOWN is received, it may mean the device has
1161	  gone away.  Deal with it.
1162	For BPF, raise the default capture buffer size to from 32k to 512k
1163	Support ps_ifdrop on Linux

1367Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release
1368
1369	New Linux libpcap implementation, which, in 2.2 and later
1370	kernels, uses PF_PACKET sockets and supports kernel packet
1371	filtering (if compiled into the kernel), and supports the "any"
1372	device for capturing on all interfaces.  Cleans up promiscuous
1373	mode better on pre-2.2 kernels, and has various other fixes
1374	(handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
1375	doesn't show duplicate packets on loopback interface, etc.).
1376
1377	Fixed HP-UX libpcap implementation to correctly get the PPA for
1378	an interface, to allow interfaces to be opened by interface name.
1379
1380	libpcap savefiles have system-independent link-layer type values
1381	in the header, rather than sometimes platform-dependent DLT_
1382	values, to make it easier to exchange capture files between
1383	different OSes.
1384
1385	Non-standard capture files produced by some Linux tcpdumps, e.g.
1386	the one from Red Hat Linux 6.2 and later, can now be read.
1387
1388	Updated autoconf stock files.
1389
1390	Filter expressions can filter on VLAN IDs and various OSI
1391	protocols, and work on Token Ring (with non-source-routed
1392	packets).
1393
1394	"pcap_open_dead()" added to allow compiling filter expressions
1395	to pcap code without opening a capture device or capture file.
1396
1397	Header files fixed to allow use in C++ programs.
1398
1399	Removed dependency on native headers for packet layout.
1400	Removed Linux specific headers that were shipped.
1401
1402	Security fixes: Strcpy replaced with strlcpy, sprintf replaced
1403	with snprintf.
1404
1405	Fixed bug that could cause subsequent "pcap_compile()"s to fail
1406	erroneously after one compile failed.
1407
1408	Assorted other bug fixes.
1409
1410	README.aix and README.linux files added to describe
1411	platform-specific issues.
1412
1413	"getifaddrs()" rather than SIOCGIFCONF used, if available.

1424Assar Westerlund  <assar@sics.se>
1425- Building outside the source code tree fixed.
1426- Changed to write out time stamps with 32-bit seconds and microseconds
1427  fields, regardless of whether those fields are 32 bits or 64 bits in
1428  the OS's native "struct timeval".
1429- Changed "pcap_lookupdev()" to dynamically grow the buffer into which
1430  the list of interfaces is read as necessary in order to hold the
1431  entire list.
1432
1433Greg Troxel <gdt@ir.bbn.com>
1434- Added a new "pcap_compile_nopcap()", which lets you compile a filter

1462- Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header
1463  formats.
1464

1470
1471- Fddi supports broadcast as reported by Jeff Macdonald
1472  (jeff@iacnet.com). Also correct ieee802 and arcnet.
1473
1474- Determine Linux pcap buffer size at run time or else it might not be

1477
1478- Fix some linux alignment problems.
1479
1480- Document promisc argument to pcap_open_live(). Reported by Ian Marsh

1502  Reported reported by Eric Jacksch (jacksch@tenebris.ca)
1503
1504- Fixed bug in pcap_dispatch() that kept it from returning on packet
1505  timeouts.
1506
1507- Changed ISLOOPBACK() macro when IFF_LOOPBACK isn't available to check
1508  for "lo" followed by an eos or digit (newer versions of Linux
1509  apparently call the loopback "lo" instead of "lo0").
1510
1511- Fixed Linux networking include files to use ints instead of longs to
1512  avoid problems with 64 bit longs on the alpha. Thanks to Cristian
1513  Gafton (gafton@redhat.com)

1649
1650- Fixed configure to test for snoop before dlpi to avoid problems under
1651  IRIX 5. Thanks to J. Eric Townsend (jet@abulafia.genmagic.com).

1654
1655- Fix two bugs related to the Solaris pre-5.3.2 bufmod bug; handle
1656  savefiles that have more than snapshot bytes of data in them (so we
1657  can read old savefiles) and avoid writing such files.
1658
1659- Added checkioctl which is used with gcc to check that the
1660  "fixincludes" script has been run.
