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

 198
 199 Thu.    March 11, 2010.  ken@netfunctional.ca/guy@alum.mit.edu.

 203         Update Endace DAG and ERF support
 204         Add support for shared libraries on Solaris, HP-UX, and AIX
 205         Build, install, and un-install shared libraries by default;
 206           don't build/install shared libraries on platforms we don't support
 207         Fix building from a directory other than the source directory
 208         Fix compiler warnings and builds on some platforms
 209         Update config.guess and config.sub
 210         Support monitor mode on mac80211 devices on Linux
 211         Fix USB memory-mapped capturing on Linux; it requires a new DLT_
 212           value
 213         On Linux, scan /sys/class/net for devices if we have it; scan
 214           it, or /proc/net/dev if we don't have /sys/class/net, even if
 215           we have getifaddrs(), as it'll find interfaces with no
 216           addresses
 217         Add limited support for reading pcap-ng files
 218         Fix BPF driver-loading error handling on AIX
 219         Support getting the full-length interface description on FreeBSD
 220         In the lexical analyzer, free up any addrinfo structure we got back
 221           from getaddrinfo().
 222         Add support for BPF and libdlpi in OpenSolaris (and SXCE)
 223         Hyphenate "link-layer" everywhere
 224         Add /sys/kernel/debug/usb/usbmon to the list of usbmon locations
 225         In pcap_read_linux_mmap(), if there are no frames available, call
 226           poll() even if we're in non-blocking mode, so we pick up
 227           errors, and check for the errors in question.
 228         Note that poll() works on BPF devices is Snow Leopard
 229         If an ENXIO or ENETDOWN is received, it may mean the device has
 230           gone away.  Deal with it.
 231         For BPF, raise the default capture buffer size to from 32k to 512k
 232         Support ps_ifdrop on Linux
 233         Added a bunch of #ifdef directives to make wpcap.dll (WinPcap) compile
 234          under cygwin.
 235         Changes to Linux mmapped captures.
 236         Fix bug where create_ring would fail for particular snaplen and
 237           buffer size combinations
 238         Update pcap-config so that it handles libpcap requiring
 239           additional libraries
 240         Add workaround for threadsafeness on Windows
 241         Add missing mapping for DLT_ENC <-> LINKTYPE_ENC

 247         Add link-layer types for AOS
 248         Add link-layer types for DECT
 249         Autoconf fixes (AIX, HP-UX, OSF/1, Tru64 cleanups)
 250         Install headers unconditionally, and include vlan.h/bluetooth.h if
 251           enabled
 252         Autoconf fixes+cleanup
 253         Support enabling/disabling bluetooth (--{en,dis}able-bluetooth)
 254         Support disabling SITA support (--without-sita)

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

 262           pcap_next_ex()
 263         Fixes for Linux USB capture
 264         DLT: Add DLT_LINUX_EVDEV
 265         DLT: Add DLT_GSMTAP_UM

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

 435
 436 Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release
 437
 438         New Linux libpcap implementation, which, in 2.2 and later
 439         kernels, uses PF_PACKET sockets and supports kernel packet
 440         filtering (if compiled into the kernel), and supports the "any"
 441         device for capturing on all interfaces.  Cleans up promiscuous
 442         mode better on pre-2.2 kernels, and has various other fixes
 443         (handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
 444         doesn't show duplicate packets on loopback interface, etc.).
 445
 446         Fixed HP-UX libpcap implementation to correctly get the PPA for
 447         an interface, to allow interfaces to be opened by interface name.
 448
 449         libpcap savefiles have system-independent link-layer type values
 450         in the header, rather than sometimes platform-dependent DLT_
 451         values, to make it easier to exchange capture files between
 452         different OSes.
 453
 454         Non-standard capture files produced by some Linux tcpdumps, e.g.
 455         the one from Red Hat Linux 6.2 and later, can now be read.
 456
 457         Updated autoconf stock files.
 458
 459         Filter expressions can filter on VLAN IDs and various OSI
 460         protocols, and work on Token Ring (with non-source-routed
 461         packets).
 462
 463         "pcap_open_dead()" added to allow compiling filter expressions
 464         to pcap code without opening a capture device or capture file.
 465
 466         Header files fixed to allow use in C++ programs.
 467
 468         Removed dependancy on native headers for packet layout.
 469         Removed Linux specific headers that were shipped.
 470
 471         Security fixes: Strcpy replaced with strlcpy, sprintf replaced
 472         with snprintf.
 473
 474         Fixed bug that could cause subsequent "pcap_compile()"s to fail
 475         erroneously after one compile failed.
 476
 477         Assorted other bug fixes.
 478
 479         README.aix and README.linux files added to describe
 480         platform-specific issues.
 481
 482         "getifaddrs()" rather than SIOCGIFCONF used, if available.
 483

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

 498 - Changed "pcap_lookupdev()" to dynamically grow the buffer into which
 499   the list of interfaces is read as necessary in order to hold the
 500   entire list.
 501
 502 Greg Troxel <gdt@ir.bbn.com>
 503 - Added a new "pcap_compile_nopcap()", which lets you compile a filter

 574   timeouts.
 575
 576 - Changed ISLOOPBACK() macro when IFF_LOOPBACK isn't available to check

 579
 580 - Fixed Linux networking include files to use ints instead of longs to
 581   avoid problems with 64 bit longs on the alpha. Thanks to Cristian

 727
 728 - Added checkioctl which is used with gcc to check that the
 729   "fixincludes" script has been run.
