   2   Summary for 1.11.0 libpcap release (so far!)
   3     Source code:
   4       Use C99 fixed-width integer types, rather than self-defined
   5         fixed-width integer types, in rpcap code.
   6       Remove an always-false pointer test from snf_read().
   7       Clean up DECnet address handling.
   8       struct pcap: Update buffer type from "void *" to "u_char *".
   9       Remove dead code that supported SITA ACN devices.
  10       Remove the TODO file.
  11     Link-layer types:
  12       Add LINKTYPE_ETW/DLT_ETW.

  23       Rename LINKTYPE_IPMB_LINUX/DLT_IPMB_LINUX to
  24         LINKTYPE_I2C_LINUX/DLT_I2C_LINUX, as it's really just an
  25         encapsulation of I2C, and is also being used for HDMI DDC.
  26         Keep DLT_IPMB_LINUX around as a #define for backwards
  27         compatibility.
  28     Packet filtering:

  48         SunOS 3.x, 4.x and 5.x before 5.3.2, and Ultrix.
  49       Add a new test program for pcap_activate().
  50       Make NetBSD build warning-free.
  51       Make Sun C build warning-free.

  54       Parameterize the interface name in reactivatetest.
  55       When necessary, trust the OS to implement ffs().
  56       At build time require a proof of suitable snprintf(3) implementation in
  57         libc (and document Solaris 9 and MinGW as unsupported because of that).
  58       Makefile.in: Update the .c.o build rule (Remove hacks for old SunOS 4).
  59       CMake: Skip snprintf(3) tests when cross-compiling.
  60     Hurd:
  61       Support network capture devices too.
  62       Fix a few device activation bugs.

  85         with libpcap.
  86       Avoid casting hack for the Windows cleanup-on-exit routine.
  87       Use %zu format for one case of printing a size_t.

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

 123     macOS:
 124       Redid the availability macros to be closer to what Apple's doing
 125         in recent SDKs, including tagging pcap-namedb.h routines.

 143       Work around a bug in Npcap 1.00 in case of driver version mismatch.
 144       Don't call WSACleanup() when handling a failed WSAStartup().
 145     BSD, macOS, AIX, Solaris 11, Linux:
 146       Add a new error PCAP_ERROR_CAPTURE_NOTSUP, for use if a capture
 147         mechanism is not present, in the hopes that, for example,
 148         attempts to capture on Windows Services for Linux 1, in which
 149         the NT kernel attempts to simulate Linux system calls but does
 150         not support packet sockets, can get an error that better
 151         indicates the underlying problem.
 152     AirPcap:
 153       Format an error message if we run out of memory.
 154     nflog:
 155       Fix count of dropped packets.

 160         double frees in some cases.
 161       Don't define SOCKET ourselves; instead, define PCAP_SOCKET as int
 162         on UN*Xes and as SOCKET on Windows.
 163       CVE-2024-8006: Fix pcap_findalldevs_ex() not to crash if passed a
 164         file:// URL with a path to a directory that cannot be opened.

 167         OpenBSD-specific link types better.
 168       Treat if_tsoffset as signed in pcapng files, as the spec says.
 169       Don't try to fix the "real" length for isochronous USB
 170         transfers if the number of USB descriptors is too large.
 171       Reject pcap files where one of the reserved fields in the
 172         "link-layer type plus other stuff" is non-zero.
 173     Building and testing:
 174       Add a configure option to help debugging (--enable-instrument-functions).
 175       Improved tests and error reporting for uses of pkg-config, and
 176         improve help message.
 177       Fix Haiku build.
 178       With CMake, install headers in CMAKE_INSTALL_INCLUDEDIR rather
 179         than just include.
 180       Build libpcap.a before building test programs.
 181       Print address family numerically, as well as symbolically,
 182         in findalldevstest.
 183       Fail with suggestions, rather than failing over to no capture
 184         support, if no capture mechanism was found.  Fixes issue #1016.
 185       Don't indent comments in Make, as that may cause them not to be
 186         recognized as comments.
 187       Don't check for libssl if we aren't going to use it.
 188       Better handle enabling and disabling of sanitizers.  Fixes issue
 189         #1171.

 199       Autoconf: Update the install-sh script to the 2020-11-14.01 version.
 200       Compile with '-Wnull-pointer-subtraction',
 201         '-Wunused-but-set-parameter', and '-Wunused-but-set-variable' in
 202         devel mode if supported.
 203       Don't ignore spaces between CMAKE_C_FLAGS and DPDK_C_FLAGS with
 204         CMake.
 205       Use noreturn and __format__ with XL C 7.0 and later.
 206       Check for the same -W flags in autotools and CMake.

 265     Source code:
 266       Use __builtin_unreachable() in PCAP_UNREACHABLE.
 267       Use AS_HELP_STRING macro instead of AC_HELP_STRING in the
 268         configure scripts, to avoid deprecation warnings.
 269       Change availability tags in pcap.h to make it easier to
 270         arrange for it to be used in Darwin releases.
 271       Use AS_HELP_STRING for --enable-remote.
 272       Fix some formatting string issues found by cppcheck.
 273       Various small code and comment cleanups.
 274       Use PCAP_ERROR (defined as -1) rather than explicit -1 for
 275         functions the documentation says return PCAP_ERROR.
 276       Remove unused code from the filter compiler.
 277       Use _declspec(deprecated(msg)) rather than __pragma(deprecated)
 278         for Windows deprecation warnings, so the message that was
 279         specified shows up.
 280       diag-control.h: define PCAP_DO_PRAGMA() iff we're going to use it.
 281       Use "%d" to print some signed ints.
 282       Use the Wayback Machine for a removed document in a comment.

 284       RDMA: Use PRIu64 to print a uint64_t.
 285     "Dead" pcap_ts from pcap_open_dead() and ..._with_tstamp_precision():
 286         Don't crash if pcap_breakloop() is called.
 287     Savefiles:
 288       Fix pcap_dispatch() to return number of packets processed, rather
 289         than 0, even at EOF.
 290       If we get an error writing the packet header, don't write the
 291         packet data.
 292       Put PFLOG UID and PID values in the header into host byte order
 293         when reading a LINKTYPE_PFLOG file.
 294       Put CAN ID field in CAN pseudo-headers for LINUX_SLL2, as we do
 295         for LINUX_SLL.
 296       Fix incorrectly-computed "real" length for isochronous USB
 297         transfers when reading savefiles.

 299       Fix pcap_offline_read() loop.
 300     Capture:
 301       Never process more than INT_MAX packets in a pcap_dispatch() call,
 302         to avoid integer overflow (issue #1087).
 303       Improve error messages for "no such device" and "permission
 304         denied" errors.
 305       SITA: Fix a typo in a variable name.
 306     Packet filtering:
 307       Get PFLOG header length from the length value in the header.
 308       Support all the direction, reason, and action types supported by
 309         all systems that support PFLOG.
 310       Don't require PFLOG support on the target machine in order to
 311         support PFLOG filtering (also fixes issue #1076).
 312       Expand abbreviations into "proto X" properly.
 313       gencode.c: Update a comment about the VLAN TPID test.

 320         CONFIG_PACKET_MMAP not configured (issue #1054).
 321       Use DLT_CAN_SOCKETCAN for CANbus interfaces (issue #1052; includes
 322         changes from pull request #1035).
 323       Make sure the CANFD_FDF can be relied on to indicate whether a
 324         CANbus packet is a CAN frame or a CAN FD frame
 325       Improve error message for "out of memory" errors for kernel
 326         filters (see issue #1089).
 327       Fix pcap_findalldevs() to find usbmon devices.
 328       Fix handling of VLAN tagged packets if the link-layer type is
 329         changed from DLT_LINUX_SLL to DLT_LINUX_SLL2 (see issue #1105).
 330       Always turn on PACKET_AUXDATA (see issue #1105).
 331       We require 2.6.27 or later, so PACKET_RESERVE is available.
 332       Make sure there's reserved space for a DLT_LINUX_SLL2 header
 333         when capturing.
 334       Correctly compute the "real" length for isochronous USB transfers.
 335       Don't have an eventfd descriptor open in non-blocking mode, so as
 336         not to waste descriptors.
 337       netfilter: Squelch a narrowing warning (To be look at before 2038).
 338     BPF capture (*BSD, macOS, AIX, Solaris 11):
 339       Fix case where a device open might fail, rather than falling back
 340         to a smaller buffer size, when the initial buffer size is too
 341         big.
 342       Use an unsigned device number to iterate over BPF devices, to

 392         try pkg-config first.
 393       If we have pkg-config and Homebrew, try to set pkg-config up to
 394         find Homebrew packages.
 395       Handle some Autoconf/make errors better.
 396       Use "git archive" for the "make releasetar" process.
 397       Remove the release candidate rcX targets.

 422       Fix building without protochain support. (GH #852)
 423       Check for a usable YACC (or Bison) and {F}lex in CMake, as we do
 424         in autotools.
 425       Only check for a C++ compiler on Haiku, as that's the only
 426         platform with C++ code, and make sure they generate code for
 427         the same instruction set bit-width (both 32-bit or both 64-bit)
 428         (issue #1112).
 429       On Solaris, check the target bit-width and set PKG_CONFIG_PATH
 430         appropriately, to handle the mess that is the D-Bus library
 431         package (issue #1112).
 432       Fix generation of pcap-config and libpcap.pc files (issue #1062).

 471 Wednesday, June 9, 2021:
 472   Summary for 1.10.1 libpcap release:
 473     Packet filtering:
 474       Fix "type XXX subtype YYY" giving a parse error
 475     Source code:
 476       Add PCAP_AVAILABLE_1_11.
 477     Building and testing:
 478       Rename struct bpf_aux_data to avoid NetBSD compile errors
 479       Squelch some compiler warnings
 480       Squelch some Bison warnings
 481       Fix cross-builds with older kernels lacking BPF_MOD and BPF_XOR
 482       Fix Bison detection for minor version 0.
 483       Fix parallel build with FreeBSD make.
 484       Get DLT_MATCHING_MAX right in gencode.c on NetBSD.
 485       Define timeradd() and timersub() if necessary.
 486       Fix Cygwin/MSYS target directories.
 487       Fix symlinking with DESTDIR.
 488       Fix generation of libpcap.pc with CMake when not building a shared
 489           library.
 490       Check for Arm64 as well as x86-64 when looking for packet.lib on
 491           Windows.
 492     Documentation:
 493       Refine Markdown in README.md.
 494       Improve the description of portrange in filters.
 495       README.linux.md isn't Markdown, rename it just README.linux.
 496     pcapng:
 497       Support reading version 1.2, which some writers produce, and which
 498           is the same as 1.0 (some new block types were added, but
 499           that's not sufficient reason to bump the minor version number,
 500           as code that understands those new block types can handle them
 501           in a 1.0 file)
 502     Linux:
 503       Drop support for text-mode USB captures, as we require a 2.6.27
 504           or later kernel (credit to Chaoyuan Peng for noting the
 505           sscanf vulnerabilities in the text-mode code that got me to
 506           realize that we didn't need this code any more)
 507       Bluetooth: fix non-blocking mode.
 508       Don't assume that all compilers used to build for Linux support
 509           the __atomic builtins
 510     Windows:
 511       Add more information in "interface disappeared" error messages, in
 512         the hopes of trying to figure out the cause.
 513       Treat ERROR_DEVICE_REMOVED as "device was removed".
 514       Indicate in the error message which "device was removed" error
 515           occurred.
 516       Report the Windows error status if PacketSendPacket() fails.
 517       Use %lu for ULONGs in error message formats.
 518       Don't treat the inability to find airpcap.dll as an error.
 519       Ignore spurious error reports by Microsoft Surface mobile
 520           telephony modem driver
 521     rpcap:
 522       Clean up error checking and error messages for server address
 523           lookup.
 524

 533        on ARM)
 534     Fix some thread safety issues
 535     pcap_findalldevs(): don't sort interfaces by unit number
 536     Always return a list of supported time-stamp types, even if only
 537         host time stamps are supported
 538     Increase the maximum snaplen for LINKTYPE_USBPCAP/DLT_USBPCAP
 539     Report the DLT description in error messages
 540     Add pcap_init() for first-time initialization and global option
 541         setting; it's not required, but may be used
 542     Remove (unused) SITA support
 543     Capture file reading:
 544         Correctly handle pcapng captures with more than one IDB with a
 545             snapshot length greater than the supported maximum
 546     Capture file writing:
 547         Create the file in pcap_dump_open_append() if it doesn't exist
 548     Packet filtering:
 549         Fix "unknown ether proto 'aarp'"
 550         Add a new filter "ifindex" for DLT_LINUX_SLL2 files on all

 576         On UN*X, don't have rpcapd tell the client why authentication
 577             failed, so a brute-force attacker can't distinguish between

 592         Handle systems without AF_INET or AF_UNIX socket support
 593         Get rid of Wireless Extensions for turning monitor mode on
 594         Proper memory sync for PACKET_MMAP (may prevent GitHub issue

 596         Drop support for libnl 1 and 2.
 597         Return error on interface going away, but not if it just went
 598             down but is still present

 602         When adjusting BPF programs, do not subtract the
 603             SLL[2]_HDR_LEN if the location is negative (special metadata
 604             offset), to preserve references to metadata; see
 605             https://github.com/the-tcpdump-group/tcpdump/issues/480#issuecomment-486827278

 608             capture loop
 609         Add support for DSA data link types
 610         For raw USB bus capture, use the snapshot length to set the
 611             buffer size, and set the len field to reflect the length
 612             in the URB (GitHub issue #808)
 613         With a timeout of zero, wait indefinitely
 614         Clean up support for some non-GNU libc C libraries

 624             ioctl is supported at all
 625         Treat ENXIO when reading packets as meaning "the interface
 626             was removed"

1064           headers
1065         Do filtering on USB and Bluetooth capturing
1066         On FreeBSD/SPARC64, use -fPIC - it's apparently necessary
1067         Check for valid port numbers (fit in a 16-bit unsigned field) in
1068           "port" filters
1069         Reject attempts to put savefiles into non-blocking mode
1070         Check for "no such device" for the "get the media types" ioctl
1071           in *BSD

1092
1093 Thu.    March 11, 2010.  ken@netfunctional.ca/guy@alum.mit.edu.
1094 Summary for 1.1.0 libpcap release
1095         Add SocketCAN capture support
1096         Add Myricom SNF API support
1097         Update Endace DAG and ERF support
1098         Add support for shared libraries on Solaris, HP-UX, and AIX
1099         Build, install, and un-install shared libraries by default;
1100           don't build/install shared libraries on platforms we don't support
1101         Fix building from a directory other than the source directory
1102         Fix compiler warnings and builds on some platforms
1103         Update config.guess and config.sub
1104         Support monitor mode on mac80211 devices on Linux
1105         Fix USB memory-mapped capturing on Linux; it requires a new DLT_
1106           value
1107         On Linux, scan /sys/class/net for devices if we have it; scan
1108           it, or /proc/net/dev if we don't have /sys/class/net, even if
1109           we have getifaddrs(), as it'll find interfaces with no
1110           addresses
1111         Add limited support for reading pcap-ng files
1112         Fix BPF driver-loading error handling on AIX
1113         Support getting the full-length interface description on FreeBSD
1114         In the lexical analyzer, free up any addrinfo structure we got back
1115           from getaddrinfo().

1117         Hyphenate "link-layer" everywhere
1118         Add /sys/kernel/debug/usb/usbmon to the list of usbmon locations
1119         In pcap_read_linux_mmap(), if there are no frames available, call
1120           poll() even if we're in non-blocking mode, so we pick up
1121           errors, and check for the errors in question.
1122         Note that poll() works on BPF devices is Snow Leopard
1123         If an ENXIO or ENETDOWN is received, it may mean the device has
1124           gone away.  Deal with it.
1125         For BPF, raise the default capture buffer size to from 32k to 512k
1126         Support ps_ifdrop on Linux

1131           buffer size combinations
1132         Update pcap-config so that it handles libpcap requiring
1133           additional libraries

1143         Autoconf fixes (AIX, HP-UX, OSF/1, Tru64 cleanups)
1144         Install headers unconditionally, and include vlan.h/bluetooth.h if
1145           enabled
1146         Autoconf fixes+cleanup
1147         Support enabling/disabling bluetooth (--{en,dis}able-bluetooth)

1152           attempt to open it in Monitor mode
1153         Add support for snapshot length for USB Memory-Mapped Interface
1154         Fix configure and build on recent Linux kernels
1155         Fix memory-mapped Linux capture to support pcap_next() and
1156           pcap_next_ex()
1157         Fixes for Linux USB capture
1158         DLT: Add DLT_LINUX_EVDEV
1159         DLT: Add DLT_GSMTAP_UM
1160         DLT: Add DLT_GSMTAP_ABIS

1179         Fix dynamic library support on OSX
1180         Return PCAP_ERROR_IFACE_NOT_UP if the interface isn't 'UP', so applications
1181          can print better diagnostic information
1182         Return PCAP_ERROR_PERM_DENIED if we don't have permission to open a device, so
1183          applications can tell the user they need to go play with permissions
1184         On Linux, ignore ENETDOWN so we can continue to capture packets if the
1185          interface goes down and comes back up again.

1329
1330 Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release
1331
1332         New Linux libpcap implementation, which, in 2.2 and later
1333         kernels, uses PF_PACKET sockets and supports kernel packet
1334         filtering (if compiled into the kernel), and supports the "any"
1335         device for capturing on all interfaces.  Cleans up promiscuous
1336         mode better on pre-2.2 kernels, and has various other fixes
1337         (handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
1338         doesn't show duplicate packets on loopback interface, etc.).
1339
1340         Fixed HP-UX libpcap implementation to correctly get the PPA for
1341         an interface, to allow interfaces to be opened by interface name.
1342
1343         libpcap savefiles have system-independent link-layer type values
1344         in the header, rather than sometimes platform-dependent DLT_
1345         values, to make it easier to exchange capture files between
1346         different OSes.
1347
1348         Non-standard capture files produced by some Linux tcpdumps, e.g.
1349         the one from Red Hat Linux 6.2 and later, can now be read.
1350
1351         Updated autoconf stock files.
1352
1353         Filter expressions can filter on VLAN IDs and various OSI
1354         protocols, and work on Token Ring (with non-source-routed
1355         packets).
1356
1357         "pcap_open_dead()" added to allow compiling filter expressions
1358         to pcap code without opening a capture device or capture file.
1359
1360         Header files fixed to allow use in C++ programs.
1361

1363         Removed Linux specific headers that were shipped.
1364
1365         Security fixes: Strcpy replaced with strlcpy, sprintf replaced
1366         with snprintf.
1367
1368         Fixed bug that could cause subsequent "pcap_compile()"s to fail
1369         erroneously after one compile failed.
1370
1371         Assorted other bug fixes.
1372
1373         README.aix and README.linux files added to describe
1374         platform-specific issues.
1375
1376         "getifaddrs()" rather than SIOCGIFCONF used, if available.

1386
1387 Assar Westerlund  <assar@sics.se>
1388 - Building outside the source code tree fixed.
1389 - Changed to write out time stamps with 32-bit seconds and microseconds
1390   fields, regardless of whether those fields are 32 bits or 64 bits in
1391   the OS's native "struct timeval".
1392 - Changed "pcap_lookupdev()" to dynamically grow the buffer into which
1393   the list of interfaces is read as necessary in order to hold the
1394   entire list.
1395
1396 Greg Troxel <gdt@ir.bbn.com>
1397 - Added a new "pcap_compile_nopcap()", which lets you compile a filter

1468   timeouts.
1469
1470 - Changed ISLOOPBACK() macro when IFF_LOOPBACK isn't available to check
1471   for "lo" followed by an eos or digit (newer versions of Linux
1472   apparently call the loopback "lo" instead of "lo0").
1473
1474 - Fixed Linux networking include files to use ints instead of longs to
1475   avoid problems with 64 bit longs on the alpha. Thanks to Cristian

1565   (cslater@imatek.com) for pointing this out.
1566
1567 - Removed FDDI ifdef's, they aren't really needed. Resulted from report

1612
1613 - Fixed configure to test for snoop before dlpi to avoid problems under
1614   IRIX 5. Thanks to J. Eric Townsend (jet@abulafia.genmagic.com).
1615
1616 - Hack around deficiency in Ultrix's make.
1617
1618 - Fix two bugs related to the Solaris pre-5.3.2 bufmod bug; handle
1619   savefiles that have more than snapshot bytes of data in them (so we
1620   can read old savefiles) and avoid writing such files.
1621
1622 - Added checkioctl which is used with gcc to check that the
1623   "fixincludes" script has been run.
1624
