 269     BSD, macOS, AIX, Solaris 11, Linux:
 270       Add a new error PCAP_ERROR_CAPTURE_NOTSUP, for use if a capture
 271         mechanism is not present, in the hopes that, for example,
 272         attempts to capture on Windows Services for Linux 1, in which
 273         the NT kernel attempts to simulate Linux system calls but does
 274         not support packet sockets, can get an error that better

 288         file:// URL with a path to a directory that cannot be opened.

 291         OpenBSD-specific link types better.
 292       Treat if_tsoffset as signed in pcapng files, as the spec says.
 293       Don't try to fix the "real" length for isochronous USB
 294         transfers if the number of USB descriptors is too large.
 295       Reject pcap files where one of the reserved fields in the
 296         "link-layer type plus other stuff" is non-zero.
 297     Building and testing:
 298       Add a configure option to help debugging (--enable-instrument-functions).

 300         improve help message.
 301       Fix Haiku build.
 302       With CMake, install headers in CMAKE_INSTALL_INCLUDEDIR rather
 303         than just include.

 305       Print address family numerically, as well as symbolically,
 306         in findalldevstest.
 307       Fail with suggestions, rather than failing over to no capture
 308         support, if no capture mechanism was found.  Fixes issue #1016.
 309       Don't indent comments in Make, as that may cause them not to be
 310         recognized as comments.
 311       Don't check for libssl if we aren't going to use it.
 312       Better handle enabling and disabling of sanitizers.  Fixes issue

 327       Don't ignore spaces between CMAKE_C_FLAGS and DPDK_C_FLAGS with
 328         CMake.
 329       Use noreturn and __format__ with XL C 7.0 and later.
 330       Check for the same -W flags in autotools and CMake.

 353       Note in man pages that errbuf arguments must point to an error
 354         buffer.
 355       Note that if pcap_findalldevs() fails it sets *alldevsp to NULL;
 356         there's no devices list to free.
 357       Explain "other addresses" in pcap_findalldevs(3PCAP).
 358       Document pcap_lookupnet(3PCAP) a bit better.

 389     Source code:
 390       Use __builtin_unreachable() in PCAP_UNREACHABLE.
 391       Use AS_HELP_STRING macro instead of AC_HELP_STRING in the
 392         configure scripts, to avoid deprecation warnings.
 393       Change availability tags in pcap.h to make it easier to
 394         arrange for it to be used in Darwin releases.
 395       Use AS_HELP_STRING for --enable-remote.
 396       Fix some formatting string issues found by cppcheck.
 397       Various small code and comment cleanups.
 398       Use PCAP_ERROR (defined as -1) rather than explicit -1 for
 399         functions the documentation says return PCAP_ERROR.
 400       Remove unused code from the filter compiler.
 401       Use _declspec(deprecated(msg)) rather than __pragma(deprecated)
 402         for Windows deprecation warnings, so the message that was
 403         specified shows up.
 404       diag-control.h: define PCAP_DO_PRAGMA() iff we're going to use it.
 405       Use "%d" to print some signed ints.
 406       Use the Wayback Machine for a removed document in a comment.
 407       Add some const qualifiers.
 408       RDMA: Use PRIu64 to print a uint64_t.
 409     "Dead" pcap_ts from pcap_open_dead() and ..._with_tstamp_precision():
 410         Don't crash if pcap_breakloop() is called.
 411     Savefiles:
 412       Fix pcap_dispatch() to return number of packets processed, rather
 413         than 0, even at EOF.
 414       If we get an error writing the packet header, don't write the
 415         packet data.
 416       Put PFLOG UID and PID values in the header into host byte order
 417         when reading a LINKTYPE_PFLOG file.
 418       Put CAN ID field in CAN pseudo-headers for LINUX_SLL2, as we do
 419         for LINUX_SLL.
 420       Fix incorrectly-computed "real" length for isochronous USB
 421         transfers when reading savefiles.
 422       Don't crash if pcap_can_set_rfmon() is called.
 423       Fix pcap_offline_read() loop.
 424     Capture:
 425       Never process more than INT_MAX packets in a pcap_dispatch() call,
 426         to avoid integer overflow (issue #1087).
 427       Improve error messages for "no such device" and "permission
 428         denied" errors.
 429       SITA: Fix a typo in a variable name.
 430     Packet filtering:
 431       Get PFLOG header length from the length value in the header.
 432       Support all the direction, reason, and action types supported by
 433         all systems that support PFLOG.
 434       Don't require PFLOG support on the target machine in order to
 435         support PFLOG filtering (also fixes issue #1076).
 436       Expand abbreviations into "proto X" properly.
 437       gencode.c: Update a comment about the VLAN TPID test.

 444         CONFIG_PACKET_MMAP not configured (issue #1054).
 445       Use DLT_CAN_SOCKETCAN for CANbus interfaces (issue #1052; includes
 446         changes from pull request #1035).
 447       Make sure the CANFD_FDF can be relied on to indicate whether a
 448         CANbus packet is a CAN frame or a CAN FD frame
 449       Improve error message for "out of memory" errors for kernel
 450         filters (see issue #1089).
 451       Fix pcap_findalldevs() to find usbmon devices.
 452       Fix handling of VLAN tagged packets if the link-layer type is
 453         changed from DLT_LINUX_SLL to DLT_LINUX_SLL2 (see issue #1105).
 454       Always turn on PACKET_AUXDATA (see issue #1105).
 455       We require 2.6.27 or later, so PACKET_RESERVE is available.
 456       Make sure there's reserved space for a DLT_LINUX_SLL2 header
 457         when capturing.
 458       Correctly compute the "real" length for isochronous USB transfers.
 459       Don't have an eventfd descriptor open in non-blocking mode, so as
 460         not to waste descriptors.
 461       netfilter: Squelch a narrowing warning (To be look at before 2038).
 462     BPF capture (*BSD, macOS, AIX, Solaris 11):
 463       Fix case where a device open might fail, rather than falling back
 464         to a smaller buffer size, when the initial buffer size is too
 465         big.
 466       Use an unsigned device number to iterate over BPF devices, to
 467         squelch a compiler warning.
 468     NetBSD:
 469       Fix handling of LINKTYPE_HDLC/DLT_HDLC.
 470     rpcap:
 471       Fix unaligned accesses in rpcapd (pull request #1037).

 481       Provide an error message for a bad authentication reply size.
 482       For link-layer types with host-endian fields in the header, fix
 483         those fields if capturing from a server with a different byte
 484         order.
 485       Suppress temporarily the warnings with "enable remote packet capture".
 486     Windows:
 487       Add support for NdisMediumIP (pull request #1027).
 488       Don't require applications using pcap to be built with VS 2015 or
 489         later.
 490       Use the correct string for the DLL VersionInfo.
 491       Remove unnecessary DllMain() function.
 492       Correctly handle ERROR_INVALID_FUNCTION from
 493         PacketGetTimestampModes() (indicate that WinPcap or an older
 494         version of Npcap is probably installed).
 495       Fix use-after-free in some cases when a pcap_t is closed.
 496       Make sure an error is returned by pcap_create_interface() if
 497         PacketOpenAdapter() fails.
 498       Return an error if the driver reports 0 timestamp modes supported.
 499       Close the ADAPTER handle for some errors in
 500         pcap_create_interface().
 501       Get rid of old unmaintained VS project files.
 502       Fix deprecation warning for pcap_handle().
 503       Npcap is now at npcap.com, not npcap.org.
 504       Make sure "no such device" and "no permission to open device"
 505         errors show up in pcap_activate(), not pcap_create() (fixes,
 506         among other things, tcpdump -i <interface-number>).
 507       npcap: squelch deprecation warnings for kernel dump mode.
 508     Haiku:
 509       Implement pcap_lib_version(), as now required.

 514       Update config.guess and config.sub.
 515       If we look for an SSL library with pkg-config in configure script,
 516         try pkg-config first.
 517       If we have pkg-config and Homebrew, try to set pkg-config up to
 518         find Homebrew packages.
 519       Handle some Autoconf/make errors better.
 520       Use "git archive" for the "make releasetar" process.
 521       Remove the release candidate rcX targets.
 522       Fix compiling on Solaris 9/SPARC and 11/AMD64.
 523       Address assorted compiler warnings.

 529       Give more details if check for usable (F)Lex fails.
 530       Fix compiling with GCC 4.6.4.
 531       Don't use add_compile_options() with CMake, as we currently don't
 532         require 2.8.12, where it first appeared.
 533       Don't provide -L/usr/lib for pkg-config --libs in pkg-config.

 544         #1101 and #1115).
 545       Cleanup various leftover cruft in the configure script.
 546       Fix building without protochain support. (GH #852)
 547       Check for a usable YACC (or Bison) and {F}lex in CMake, as we do
 548         in autotools.
 549       Only check for a C++ compiler on Haiku, as that's the only
 550         platform with C++ code, and make sure they generate code for
 551         the same instruction set bit-width (both 32-bit or both 64-bit)
 552         (issue #1112).
 553       On Solaris, check the target bit-width and set PKG_CONFIG_PATH
 554         appropriately, to handle the mess that is the D-Bus library
 555         package (issue #1112).
 556       Fix generation of pcap-config and libpcap.pc files (issue #1062).

 593       Document PCAP_ERROR_NOT_ACTIVATED for more routines.
 594
 595 Wednesday, June 9, 2021:
 596   Summary for 1.10.1 libpcap release:
 597     Packet filtering:
 598       Fix "type XXX subtype YYY" giving a parse error
 599     Source code:
 600       Add PCAP_AVAILABLE_1_11.
 601     Building and testing:
 602       Rename struct bpf_aux_data to avoid NetBSD compile errors
 603       Squelch some compiler warnings
 604       Squelch some Bison warnings
 605       Fix cross-builds with older kernels lacking BPF_MOD and BPF_XOR
 606       Fix Bison detection for minor version 0.
 607       Fix parallel build with FreeBSD make.
 608       Get DLT_MATCHING_MAX right in gencode.c on NetBSD.
 609       Define timeradd() and timersub() if necessary.
 610       Fix Cygwin/MSYS target directories.
 611       Fix symlinking with DESTDIR.
 612       Fix generation of libpcap.pc with CMake when not building a shared
 613           library.
 614       Check for Arm64 as well as x86-64 when looking for packet.lib on
 615           Windows.
 616     Documentation:
 617       Refine Markdown in README.md.
 618       Improve the description of portrange in filters.
 619       README.linux.md isn't Markdown, rename it just README.linux.
 620     pcapng:
 621       Support reading version 1.2, which some writers produce, and which
 622           is the same as 1.0 (some new block types were added, but
 623           that's not sufficient reason to bump the minor version number,
 624           as code that understands those new block types can handle them
 625           in a 1.0 file)
 626     Linux:
 627       Drop support for text-mode USB captures, as we require a 2.6.27
 628           or later kernel (credit to Chaoyuan Peng for noting the
 629           sscanf vulnerabilities in the text-mode code that got me to
 630           realize that we didn't need this code any more)
 631       Bluetooth: fix non-blocking mode.
 632       Don't assume that all compilers used to build for Linux support
 633           the __atomic builtins
 634     Windows:
 635       Add more information in "interface disappeared" error messages, in
 636         the hopes of trying to figure out the cause.
 637       Treat ERROR_DEVICE_REMOVED as "device was removed".
 638       Indicate in the error message which "device was removed" error
 639           occurred.
 640       Report the Windows error status if PacketSendPacket() fails.
 641       Use %lu for ULONGs in error message formats.
 642       Don't treat the inability to find airpcap.dll as an error.
 643       Ignore spurious error reports by Microsoft Surface mobile
 644           telephony modem driver
 645     rpcap:
 646       Clean up error checking and error messages for server address
 647           lookup.
 648

 655     Handle the pcap private data in a fashion that makes fewer
 656        assumptions about memory layouts (might fix GitHub issue #940
 657        on ARM)
 658     Fix some thread safety issues
 659     pcap_findalldevs(): don't sort interfaces by unit number
 660     Always return a list of supported time-stamp types, even if only
 661         host time stamps are supported
 662     Increase the maximum snaplen for LINKTYPE_USBPCAP/DLT_USBPCAP
 663     Report the DLT description in error messages
 664     Add pcap_init() for first-time initialization and global option
 665         setting; it's not required, but may be used
 666     Remove (unused) SITA support
 667     Capture file reading:
 668         Correctly handle pcapng captures with more than one IDB with a
 669             snapshot length greater than the supported maximum
 670     Capture file writing:
 671         Create the file in pcap_dump_open_append() if it doesn't exist
 672     Packet filtering:
 673         Fix "unknown ether proto 'aarp'"
 674         Add a new filter "ifindex" for DLT_LINUX_SLL2 files on all

 676         Add a hack to the optimizer to try to catch certain optimizer
 677             loops (should prevent GitHub issue #112)
 678         Show special Linux BPF offsets symbolically in bpf_image() and
 679             bpf_dump()
 680         Added support for ICMPv6 types 1-4 as tokens with names
 681         Remove undocumented and rather old "ether proto" protocols
 682         Catch invalid IPv4 addresses in filters

 685         Fix various security issues reported by Charles Smith at Tangible
 686             Security
 687         Fix various security issues reported by Include Security
 688         Fix some issues found by cppcheck.
 689         Add some overflow checks in the optimizer
 690     rpcap:
 691         Support rpcap-over-TLS
 692         Redo protocol version negotiation to avoid problems with old

1187         Don't crash if "wlan addr{1,2,3,4}" are used without 802.11
1188           headers
1189         Do filtering on USB and Bluetooth capturing
1190         On FreeBSD/SPARC64, use -fPIC - it's apparently necessary
1191         Check for valid port numbers (fit in a 16-bit unsigned field) in
1192           "port" filters
1193         Reject attempts to put savefiles into non-blocking mode

1225         Fix building from a directory other than the source directory
1226         Fix compiler warnings and builds on some platforms
1227         Update config.guess and config.sub
1228         Support monitor mode on mac80211 devices on Linux
1229         Fix USB memory-mapped capturing on Linux; it requires a new DLT_
1230           value
1231         On Linux, scan /sys/class/net for devices if we have it; scan
1232           it, or /proc/net/dev if we don't have /sys/class/net, even if
1233           we have getifaddrs(), as it'll find interfaces with no
1234           addresses
1235         Add limited support for reading pcap-ng files
1236         Fix BPF driver-loading error handling on AIX

1241         Hyphenate "link-layer" everywhere
1242         Add /sys/kernel/debug/usb/usbmon to the list of usbmon locations
1243         In pcap_read_linux_mmap(), if there are no frames available, call
1244           poll() even if we're in non-blocking mode, so we pick up
1245           errors, and check for the errors in question.
1246         Note that poll() works on BPF devices is Snow Leopard
1247         If an ENXIO or ENETDOWN is received, it may mean the device has
1248           gone away.  Deal with it.
1249         For BPF, raise the default capture buffer size to from 32k to 512k
1250         Support ps_ifdrop on Linux

1255           buffer size combinations
1256         Update pcap-config so that it handles libpcap requiring
1257           additional libraries

1267         Autoconf fixes (AIX, HP-UX, OSF/1, Tru64 cleanups)
1268         Install headers unconditionally, and include vlan.h/bluetooth.h if
1269           enabled
1270         Autoconf fixes+cleanup

1276           attempt to open it in Monitor mode
1277         Add support for snapshot length for USB Memory-Mapped Interface
1278         Fix configure and build on recent Linux kernels

1280           pcap_next_ex()
1281         Fixes for Linux USB capture
1282         DLT: Add DLT_LINUX_EVDEV

1305          can print better diagnostic information
1306         Return PCAP_ERROR_PERM_DENIED if we don't have permission to open a device, so
1307          applications can tell the user they need to go play with permissions

1453
1454 Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release
1455
1456         New Linux libpcap implementation, which, in 2.2 and later
1457         kernels, uses PF_PACKET sockets and supports kernel packet
1458         filtering (if compiled into the kernel), and supports the "any"
1459         device for capturing on all interfaces.  Cleans up promiscuous
1460         mode better on pre-2.2 kernels, and has various other fixes
1461         (handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
1462         doesn't show duplicate packets on loopback interface, etc.).
1463
1464         Fixed HP-UX libpcap implementation to correctly get the PPA for
1465         an interface, to allow interfaces to be opened by interface name.
1466
1467         libpcap savefiles have system-independent link-layer type values
1468         in the header, rather than sometimes platform-dependent DLT_
1469         values, to make it easier to exchange capture files between
1470         different OSes.
1471
1472         Non-standard capture files produced by some Linux tcpdumps, e.g.
1473         the one from Red Hat Linux 6.2 and later, can now be read.
1474
1475         Updated autoconf stock files.
1476
1477         Filter expressions can filter on VLAN IDs and various OSI
1478         protocols, and work on Token Ring (with non-source-routed
1479         packets).
1480
1481         "pcap_open_dead()" added to allow compiling filter expressions
1482         to pcap code without opening a capture device or capture file.
1483
1484         Header files fixed to allow use in C++ programs.
1485
1486         Removed dependency on native headers for packet layout.
1487         Removed Linux specific headers that were shipped.
1488
1489         Security fixes: Strcpy replaced with strlcpy, sprintf replaced
1490         with snprintf.
1491
1492         Fixed bug that could cause subsequent "pcap_compile()"s to fail
1493         erroneously after one compile failed.
1494
1495         Assorted other bug fixes.
1496
1497         README.aix and README.linux files added to describe
1498         platform-specific issues.
1499
1500         "getifaddrs()" rather than SIOCGIFCONF used, if available.
1501

1510
1511 Assar Westerlund  <assar@sics.se>
1512 - Building outside the source code tree fixed.
1513 - Changed to write out time stamps with 32-bit seconds and microseconds
1514   fields, regardless of whether those fields are 32 bits or 64 bits in
1515   the OS's native "struct timeval".
1516 - Changed "pcap_lookupdev()" to dynamically grow the buffer into which
1517   the list of interfaces is read as necessary in order to hold the
1518   entire list.
1519
1520 Greg Troxel <gdt@ir.bbn.com>
1521 - Added a new "pcap_compile_nopcap()", which lets you compile a filter
1522   expression into a BPF program without having an open live capture or
1523   capture file.
1524

1592   timeouts.
1593
1594 - Changed ISLOOPBACK() macro when IFF_LOOPBACK isn't available to check
1595   for "lo" followed by an eos or digit (newer versions of Linux
1596   apparently call the loopback "lo" instead of "lo0").
1597
1598 - Fixed Linux networking include files to use ints instead of longs to
1599   avoid problems with 64 bit longs on the alpha. Thanks to Cristian

1689   (cslater@imatek.com) for pointing this out.
1690
1691 - Removed FDDI ifdef's, they aren't really needed. Resulted from report

1736
1737 - Fixed configure to test for snoop before dlpi to avoid problems under
1738   IRIX 5. Thanks to J. Eric Townsend (jet@abulafia.genmagic.com).
1739
1740 - Hack around deficiency in Ultrix's make.
1741
1742 - Fix two bugs related to the Solaris pre-5.3.2 bufmod bug; handle
1743   savefiles that have more than snapshot bytes of data in them (so we
1744   can read old savefiles) and avoid writing such files.
1745
1746 - Added checkioctl which is used with gcc to check that the
1747   "fixincludes" script has been run.
1748
