222 Source code:

238 Use "%d" to print some signed ints.
239 Use the Wayback Machine for a removed document in a comment.

280 Make sure the CANFD_FDF can be relied on to indicate whether a
281 CANbus packet is a CAN frame or a CAN FD frame

286 changed from DLT_LINUX_SLL to DLT_LINUX_SLL2 (see issue #1105).
287 Always turn on PACKET_AUXDATA (see issue #1105).

295 BPF capture (*BSD, macOS, AIX, Solaris 11):
296 Fix case where a device open might fail, rather than falling back

384 the same instruction set bit-width (both 32-bit or both 64-bit)
385 (issue #1112).
386 On Solaris, check the target bit-width and set PKG_CONFIG_PATH

453 pcapng:
454 Support reading version 1.2, which some writers produce, and which
455 is the same as 1.0 (some new block types were added, but
456 that's not sufficient reason to bump the minor version number,
457 as code that understands those new block types can handle them
458 in a 1.0 file)
459 Linux:
460 Drop support for text-mode USB captures, as we require a 2.6.27
461 or later kernel (credit to Chaoyuan Peng for noting the
462 sscanf vulnerabilities in the text-mode code that got me to
463 realize that we didn't need this code any more)
464 Bluetooth: fix non-blocking mode.
465 Don't assume that all compilers used to build for Linux support
466 the __atomic builtins
467 Windows:
468 Add more information in "interface disappeared" error messages, in
469 the hopes of trying to figure out the cause.
470 Treat ERROR_DEVICE_REMOVED as "device was removed".
471 Indicate in the error message which "device was removed" error

474 Use %lu for ULONGs in error message formats.
475 Don't treat the inability to find airpcap.dll as an error.

487 Add pcap_datalink_val_to_description_or_dlt()

1021 headers
1022 Do filtering on USB and Bluetooth capturing
1023 On FreeBSD/SPARC64, use -fPIC - it's apparently necessary
1024 Check for valid port numbers (fit in a 16-bit unsigned field) in
1025 "port" filters
1026 Reject attempts to put savefiles into non-blocking mode
1027 Check for "no such device" for the "get the media types" ioctl

1060 Update config.guess and config.sub
1061 Support monitor mode on mac80211 devices on Linux
1062 Fix USB memory-mapped capturing on Linux; it requires a new DLT_

1064 On Linux, scan /sys/class/net for devices if we have it; scan
1065 it, or /proc/net/dev if we don't have /sys/class/net, even if
1066 we have getifaddrs(), as it'll find interfaces with no
1067 addresses

1074 Hyphenate "link-layer" everywhere
1075 Add /sys/kernel/debug/usb/usbmon to the list of usbmon locations
1076 In pcap_read_linux_mmap(), if there are no frames available, call
1077 poll() even if we're in non-blocking mode, so we pick up
1078 errors, and check for the errors in question.
1079 Note that poll() works on BPF devices is Snow Leopard
1080 If an ENXIO or ENETDOWN is received, it may mean the device has
1081 gone away. Deal with it.
1082 For BPF, raise the default capture buffer size to from 32k to 512k
1083 Support ps_ifdrop on Linux
1084 Added a bunch of #ifdef directives to make wpcap.dll (WinPcap) compile

1109 attempt to open it in Monitor mode
1110 Add support for snapshot length for USB Memory-Mapped Interface
1111 Fix configure and build on recent Linux kernels

1138 can print better diagnostic information
1139 Return PCAP_ERROR_PERM_DENIED if we don't have permission to open a device, so
1140 applications can tell the user they need to go play with permissions
1141 On Linux, ignore ENETDOWN so we can continue to capture packets if the
1142 interface goes down and comes back up again.
1143 On Linux, support new tpacket frame headers (2.6.27+)

1189 Fixes in add_or_find_if() & pcap_findalldevs() to optimize generating
1190 device lists

1286
1287 Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release
1288
1289 New Linux libpcap implementation, which, in 2.2 and later
1290 kernels, uses PF_PACKET sockets and supports kernel packet
1291 filtering (if compiled into the kernel), and supports the "any"
1292 device for capturing on all interfaces. Cleans up promiscuous
1293 mode better on pre-2.2 kernels, and has various other fixes
1294 (handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
1295 doesn't show duplicate packets on loopback interface, etc.).
1296
1297 Fixed HP-UX libpcap implementation to correctly get the PPA for
1298 an interface, to allow interfaces to be opened by interface name.
1299
1300 libpcap savefiles have system-independent link-layer type values
1301 in the header, rather than sometimes platform-dependent DLT_
1302 values, to make it easier to exchange capture files between
1303 different OSes.
1304
1305 Non-standard capture files produced by some Linux tcpdumps, e.g.
1306 the one from Red Hat Linux 6.2 and later, can now be read.
1307
1308 Updated autoconf stock files.
1309
1310 Filter expressions can filter on VLAN IDs and various OSI
1311 protocols, and work on Token Ring (with non-source-routed
1312 packets).
1313
1314 "pcap_open_dead()" added to allow compiling filter expressions
1315 to pcap code without opening a capture device or capture file.
1316
1317 Header files fixed to allow use in C++ programs.
1318
1319 Removed dependency on native headers for packet layout.
1320 Removed Linux specific headers that were shipped.
1321
1322 Security fixes: Strcpy replaced with strlcpy, sprintf replaced
1323 with snprintf.
1324
1325 Fixed bug that could cause subsequent "pcap_compile()"s to fail
1326 erroneously after one compile failed.
1327
1328 Assorted other bug fixes.
1329
1330 README.aix and README.linux files added to describe
1331 platform-specific issues.
1332
1333 "getifaddrs()" rather than SIOCGIFCONF used, if available.
1334

1339 - Fixes for NetBSD.
1340 - Support added for OpenBSD DLT_LOOP and BSD/OS DLT_C_HDLC (Cisco HDLC),
1341 and changes to work around different BSDs having different DLT_ types
1342 with the same numeric value.
1343
1344 Assar Westerlund <assar@sics.se>
1345 - Building outside the source code tree fixed.
1346 - Changed to write out time stamps with 32-bit seconds and microseconds
1347 fields, regardless of whether those fields are 32 bits or 64 bits in
1348 the OS's native "struct timeval".
1349 - Changed "pcap_lookupdev()" to dynamically grow the buffer into which
1350 the list of interfaces is read as necessary in order to hold the
1351 entire list.
1352
1353 Greg Troxel <gdt@ir.bbn.com>
1354 - Added a new "pcap_compile_nopcap()", which lets you compile a filter
1355 expression into a BPF program without having an open live capture or
1356 capture file.
1357
1358 v0.4 Sat Jul 25 12:40:09 PDT 1998

1368 options to disable gcc and to force a particular packet capture type.
1369
1370 - Added support for Fore ATM interfaces (qaa and fa) under IRIX. Thanks
1371 to John Hawkinson (jhawk@mit.edu)
1372
1373 - Change Linux PPP and SLIP to use DLT_RAW since the kernel does not
1374 supply any "link layer" data.

1377 Thanks to Thomas Sailer (sailer@ife.ee.ethz.ch)
1378
1379 - Change IRIX PPP to use DLT_RAW since the kernel does not supply any
1380 "link layer" data.
1381
1382 - Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header
1383 formats.
1384
1385 - Added some new SGI snoop interface types. Thanks to Steve Alexander
1386 (sca@refugee.engr.sgi.com)
1387
1388 - Fixes for HP-UX 10.20 (which is similar to HP-UX 9). Thanks to

1392 (jeff@iacnet.com). Also correct ieee802 and arcnet.
1393
1394 - Determine Linux pcap buffer size at run time or else it might not be
1395 big enough for some interface types (e.g. FDDI). Thanks to Jes

1397
1398 - Fix some linux alignment problems.
1399
1400 - Document promisc argument to pcap_open_live(). Reported by Ian Marsh

1574
1575 - Fix two bugs related to the Solaris pre-5.3.2 bufmod bug; handle
1576 savefiles that have more than snapshot bytes of data in them (so we
1577 can read old savefiles) and avoid writing such files.
1578
1579 - Added checkioctl which is used with gcc to check that the
1580 "fixincludes" script has been run.
