   4           pcap_datalink() when reading pcap-ng files
   5         Add support for "wlan ra" and "wlan ta", to check the RA and TA
   6           of WLAN frames that have them
   7         Don't crash if "wlan addr{1,2,3,4}" are used without 802.11
   8           headers
   9         Do filtering on USB and Bluetooth capturing
  10         On FreeBSD/SPARC64, use -fPIC - it's apparently necessary
  11         Check for valid port numbers (fit in a 16-bit unsigned field) in
  12           "port" filters
  13         Reject attempts to put savefiles into non-blocking mode
  14         Check for "no such device" for the "get the media types" ioctl
  15           in *BSD
  16         Improve error messages from bpf_open(), and let it do the error

  37 Thu.    March 11, 2010.  ken@netfunctional.ca/guy@alum.mit.edu.
  38 Summary for 1.1.0 libpcap release
  39         Add SocketCAN capture support
  40         Add Myricom SNF API support
  41         Update Endace DAG and ERF support
  42         Add support for shared libraries on Solaris, HP-UX, and AIX
  43         Build, install, and un-install shared libraries by default;
  44           don't build/install shared libraries on platforms we don't support
  45         Fix building from a directory other than the source directory
  46         Fix compiler warnings and builds on some platforms
  47         Update config.guess and config.sub
  48         Support monitor mode on mac80211 devices on Linux
  49         Fix USB memory-mapped capturing on Linux; it requires a new DLT_
  50           value
  51         On Linux, scan /sys/class/net for devices if we have it; scan
  52           it, or /proc/net/dev if we don't have /sys/class/net, even if
  53           we have getifaddrs(), as it'll find interfaces with no
  54           addresses
  55         Add limited support for reading pcap-ng files
  56         Fix BPF driver-loading error handling on AIX
  57         Support getting the full-length interface description on FreeBSD
  58         In the lexical analyzer, free up any addrinfo structure we got back
  59           from getaddrinfo().
  60         Add support for BPF and libdlpi in OpenSolaris (and SXCE)
  61         Hyphenate "link-layer" everywhere
  62         Add /sys/kernel/debug/usb/usbmon to the list of usbmon locations
  63         In pcap_read_linux_mmap(), if there are no frames available, call
  64           poll() even if we're in non-blocking mode, so we pick up
  65           errors, and check for the errors in question.
  66         Note that poll() works on BPF devices is Snow Leopard
  67         If an ENXIO or ENETDOWN is received, it may mean the device has
  68           gone away.  Deal with it.
  69         For BPF, raise the default capture buffer size to from 32k to 512k
  70         Support ps_ifdrop on Linux
  71         Added a bunch of #ifdef directives to make wpcap.dll (WinPcap) compile
  72          under cygwin.
  73         Changes to Linux mmapped captures.
  74         Fix bug where create_ring would fail for particular snaplen and
  75           buffer size combinations

  87         Autoconf fixes (AIX, HP-UX, OSF/1, Tru64 cleanups)
  88         Install headers unconditionally, and include vlan.h/bluetooth.h if
  89           enabled
  90         Autoconf fixes+cleanup
  91         Support enabling/disabling bluetooth (--{en,dis}able-bluetooth)
  92         Support disabling SITA support (--without-sita)
  93         Return -1 on failure to create packet ring (if supported but
  94           creation failed)
  95         Fix handling of 'any' device, so that it can be opened, and no longer

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

 145
 146         Put the public libpcap headers into a pcap subdirectory in both the
 147          source directory and the target include directory, and have include
 148          files at the top-level directory to include those headers, for

 165         When building a shared library, build with "-fPIC" on Linux to support x86_64
 166         Link with "$(CC) -shared" rather than "ld -shared" when building a
 167          ".so" shared library
 168         Add support for autoconf 2.60
 169         Fixes to discard unread packets when changing filters
 170         Changes to handle name changes in the DAG library resulting from
 171          switching to libtool.
 172         Add support for new DAG ERF types.
 173         Add an explicit "-ldag" when building the shared library, so the DAG

 273
 274 Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release
 275
 276         New Linux libpcap implementation, which, in 2.2 and later
 277         kernels, uses PF_PACKET sockets and supports kernel packet
 278         filtering (if compiled into the kernel), and supports the "any"
 279         device for capturing on all interfaces.  Cleans up promiscuous
 280         mode better on pre-2.2 kernels, and has various other fixes
 281         (handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
 282         doesn't show duplicate packets on loopback interface, etc.).
 283
 284         Fixed HP-UX libpcap implementation to correctly get the PPA for
 285         an interface, to allow interfaces to be opened by interface name.
 286
 287         libpcap savefiles have system-independent link-layer type values
 288         in the header, rather than sometimes platform-dependent DLT_
 289         values, to make it easier to exchange capture files between
 290         different OSes.
 291
 292         Non-standard capture files produced by some Linux tcpdumps, e.g.
 293         the one from Red Hat Linux 6.2 and later, can now be read.
 294
 295         Updated autoconf stock files.
 296
 297         Filter expressions can filter on VLAN IDs and various OSI
 298         protocols, and work on Token Ring (with non-source-routed
 299         packets).
 300
 301         "pcap_open_dead()" added to allow compiling filter expressions
 302         to pcap code without opening a capture device or capture file.
 303
 304         Header files fixed to allow use in C++ programs.
 305
 306         Removed dependancy on native headers for packet layout.
 307         Removed Linux specific headers that were shipped.
 308
 309         Security fixes: Strcpy replaced with strlcpy, sprintf replaced
 310         with snprintf.
 311
 312         Fixed bug that could cause subsequent "pcap_compile()"s to fail
 313         erroneously after one compile failed.
 314
 315         Assorted other bug fixes.
 316
 317         README.aix and README.linux files added to describe
 318         platform-specific issues.
 319
 320         "getifaddrs()" rather than SIOCGIFCONF used, if available.
 321
 322 v0.5 Sat Jun 10 11:09:15 PDT 2000
 323
 324 itojun@iijlab.net
 325 - Brought in KAME IPv6/IPsec bpf compiler.
 326 - Fixes for NetBSD.
 327 - Support added for OpenBSD DLT_LOOP and BSD/OS DLT_C_HDLC (Cisco HDLC),
 328   and changes to work around different BSDs having different DLT_ types
 329   with the same numeric value.
 330
 331 Assar Westerlund  <assar@sics.se>
 332 - Building outside the source code tree fixed.
 333 - Changed to write out time stamps with 32-bit seconds and microseconds
 334   fields, regardless of whether those fields are 32 bits or 64 bits in
 335   the OS's native "struct timeval".
 336 - Changed "pcap_lookupdev()" to dynamically grow the buffer into which
 337   the list of interfaces is read as necessary in order to hold the
 338   entire list.
 339
 340 Greg Troxel <gdt@ir.bbn.com>
 341 - Added a new "pcap_compile_nopcap()", which lets you compile a filter
 342   expression into a BPF program without having an open live capture or
 343   capture file.
 344
