 159           of WLAN frames that have them
 160         Don't crash if "wlan addr{1,2,3,4}" are used without 802.11
 161           headers
 162         Do filtering on USB and Bluetooth capturing
 163         On FreeBSD/SPARC64, use -fPIC - it's apparently necessary
 164         Check for valid port numbers (fit in a 16-bit unsigned field) in
 165           "port" filters
 166         Reject attempts to put savefiles into non-blocking mode

 189
 190 Thu.    March 11, 2010.  ken@netfunctional.ca/guy@alum.mit.edu.

 195         Add support for shared libraries on Solaris, HP-UX, and AIX
 196         Build, install, and un-install shared libraries by default;
 197           don't build/install shared libraries on platforms we don't support
 198         Fix building from a directory other than the source directory
 199         Fix compiler warnings and builds on some platforms
 200         Update config.guess and config.sub
 201         Support monitor mode on mac80211 devices on Linux
 202         Fix USB memory-mapped capturing on Linux; it requires a new DLT_
 203           value
 204         On Linux, scan /sys/class/net for devices if we have it; scan
 205           it, or /proc/net/dev if we don't have /sys/class/net, even if
 206           we have getifaddrs(), as it'll find interfaces with no
 207           addresses
 208         Add limited support for reading pcap-ng files
 209         Fix BPF driver-loading error handling on AIX

 212           from getaddrinfo().
 213         Add support for BPF and libdlpi in OpenSolaris (and SXCE)
 214         Hyphenate "link-layer" everywhere
 215         Add /sys/kernel/debug/usb/usbmon to the list of usbmon locations
 216         In pcap_read_linux_mmap(), if there are no frames available, call
 217           poll() even if we're in non-blocking mode, so we pick up
 218           errors, and check for the errors in question.
 219         Note that poll() works on BPF devices is Snow Leopard
 220         If an ENXIO or ENETDOWN is received, it may mean the device has
 221           gone away.  Deal with it.
 222         For BPF, raise the default capture buffer size to from 32k to 512k
 223         Support ps_ifdrop on Linux
 224         Added a bunch of #ifdef directives to make wpcap.dll (WinPcap) compile
 225          under cygwin.
 226         Changes to Linux mmapped captures.
 227         Fix bug where create_ring would fail for particular snaplen and
 228           buffer size combinations
 229         Update pcap-config so that it handles libpcap requiring
 230           additional libraries
 231         Add workaround for threadsafeness on Windows
 232         Add missing mapping for DLT_ENC <-> LINKTYPE_ENC

 238         Add link-layer types for AOS
 239         Add link-layer types for DECT
 240         Autoconf fixes (AIX, HP-UX, OSF/1, Tru64 cleanups)
 241         Install headers unconditionally, and include vlan.h/bluetooth.h if
 242           enabled
 243         Autoconf fixes+cleanup
 244         Support enabling/disabling bluetooth (--{en,dis}able-bluetooth)
 245         Support disabling SITA support (--without-sita)

 247           creation failed)
 248         Fix handling of 'any' device, so that it can be opened, and no longer
 249           attempt to open it in Monitor mode
 250         Add support for snapshot length for USB Memory-Mapped Interface
 251         Fix configure and build on recent Linux kernels

 253           pcap_next_ex()
 254         Fixes for Linux USB capture
 255         DLT: Add DLT_LINUX_EVDEV
 256         DLT: Add DLT_GSMTAP_UM
 257         DLT: Add DLT_GSMTAP_ABIS

 278          can print better diagnostic information
 279         Return PCAP_ERROR_PERM_DENIED if we don't have permission to open a device, so
 280          applications can tell the user they need to go play with permissions
 281         On Linux, ignore ENETDOWN so we can continue to capture packets if the
 282          interface goes down and comes back up again.

 426
 427 Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release
 428
 429         New Linux libpcap implementation, which, in 2.2 and later
 430         kernels, uses PF_PACKET sockets and supports kernel packet
 431         filtering (if compiled into the kernel), and supports the "any"
 432         device for capturing on all interfaces.  Cleans up promiscuous
 433         mode better on pre-2.2 kernels, and has various other fixes
 434         (handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
 435         doesn't show duplicate packets on loopback interface, etc.).
 436
 437         Fixed HP-UX libpcap implementation to correctly get the PPA for
 438         an interface, to allow interfaces to be opened by interface name.
 439
 440         libpcap savefiles have system-independent link-layer type values
 441         in the header, rather than sometimes platform-dependent DLT_
 442         values, to make it easier to exchange capture files between
 443         different OSes.
 444
 445         Non-standard capture files produced by some Linux tcpdumps, e.g.
 446         the one from Red Hat Linux 6.2 and later, can now be read.
 447
 448         Updated autoconf stock files.
 449
 450         Filter expressions can filter on VLAN IDs and various OSI
 451         protocols, and work on Token Ring (with non-source-routed
 452         packets).
 453
 454         "pcap_open_dead()" added to allow compiling filter expressions
 455         to pcap code without opening a capture device or capture file.
 456
 457         Header files fixed to allow use in C++ programs.
 458
 459         Removed dependancy on native headers for packet layout.
 460         Removed Linux specific headers that were shipped.
 461
 462         Security fixes: Strcpy replaced with strlcpy, sprintf replaced
 463         with snprintf.
 464
 465         Fixed bug that could cause subsequent "pcap_compile()"s to fail
 466         erroneously after one compile failed.
 467
 468         Assorted other bug fixes.
 469
 470         README.aix and README.linux files added to describe
 471         platform-specific issues.
 472
 473         "getifaddrs()" rather than SIOCGIFCONF used, if available.
 474

 484 Assar Westerlund  <assar@sics.se>
 485 - Building outside the source code tree fixed.
 486 - Changed to write out time stamps with 32-bit seconds and microseconds

 489 - Changed "pcap_lookupdev()" to dynamically grow the buffer into which
 490   the list of interfaces is read as necessary in order to hold the
 491   entire list.
 492
 493 Greg Troxel <gdt@ir.bbn.com>
 494 - Added a new "pcap_compile_nopcap()", which lets you compile a filter
 495   expression into a BPF program without having an open live capture or
 496   capture file.

 570
 571 - Fixed Linux networking include files to use ints instead of longs to
 572   avoid problems with 64 bit longs on the alpha. Thanks to Cristian

 718
 719 - Added checkioctl which is used with gcc to check that the
 720   "fixincludes" script has been run.
