    1 Monthday, Month DD, YYYY
    2   Summary for 1.10.1 libpcap release (so far!)
    3     Packet filtering:
    4       Fix "type XXX subtype YYY" giving a parse error
    5     Source code:
    6       Add PCAP_AVAILABLE_1_11.
    7     Building and testing:
    8       Rename struct bpf_aux_data to avoid NetBSD compile errors
    9       Squelch some compiler warnings
   10       Squelch some Bison warnings
   11       Fix cross-builds with older kernels lacking BPF_MOD and BPF_XOR
   12       Fix Bison detection for minor version 0.
   13       Fix parallel build with FreeBSD make.
   14       Get DLT_MATCHING_MAX right in gencode.c on NetBSD.
   15       Define timeradd() and timersub() if necessary.
   16       Fix Cygwin/MSYS target directories.
   17       Fix symlinking with DESTDIR.
   18       Fix generation of libpcap.pc with CMake when not building a shared
   19           library.
   20       Check for Arm64 as well as x86-64 when looking for packet.lib on
   21           Windows.
   22     Documentation:
   23       Refine Markdown in README.md.
   24       Improve the description of portrange in filters.
   25       README.linux.md isn't Markdown, rename it just README.linux.
   26     pcapng:
   27       Support reading version 1.2, which some writers produce, and which
   28           is the same as 1.0 (some new block types were added, but
   29           that's not sufficient reason to bump the minor version number,
   30           as code that understands those new block types can handle them
   31           in a 1.0 file)
   32     Linux:
   33       Drop support for text-mode USB captures, as we require a 2.6.27
   34           or later kernel (credit to Chaoyuan Peng for noting the
   35           sscanf vulnerabilities in the text-mode code that got me to
   36           realize that we didn't need this code any more)
   37       Bluetooth: fix non-blocking mode.
   38       Don't assume that all compilers used to build for Linux support
   39           the __atomic builtins
   40     Windows:
   41       Add more information in "interface disappeared" error messages, in
   42         the hopes of trying to figure out the cause.
   43       Treat ERROR_DEVICE_REMOVED as "device was removed".
   44       Indicate in the error message which "device was removed" error
   45           occurred.
   46       Report the Windows error status if PacketSendPacket() fails.
   47       Use %lu for ULONGs in error message formats.
   48       Don't treat the inability to find airpcap.dll as an error.
   49       Ignore spurious error reports by Microsoft Surface mobile
   50           telephony modem driver
   51     rpcap:
   52       Clean up error checking and error messages for server address
   53           lookup.
   54

   61     Handle the pcap private data in a fashion that makes fewer
   62        assumptions about memory layouts (might fix GitHub issue #940

   64     Fix some thread safety issues
   65     pcap_findalldevs(): don't sort interfaces by unit number

   67         host time stamps are supported
   68     Increase the maximum snaplen for LINKTYPE_USBPCAP/DLT_USBPCAP
   69     Report the DLT description in error messages
   70     Add pcap_init() for first-time initialization and global option
   71         setting; it's not required, but may be used
   72     Remove (unused) SITA support
   73     Capture file reading:
   74         Correctly handle pcapng captures with more than one IDB with a
   75             snspshot length greater than the supported maximum
   76     Capture file writing:
   77         Create the file in pcap_dump_open_append() if it doesn't exist
   78     Packet filtering:
   79         Fix "unknown ether proto 'aarp'"

   81             platforms and live Linux captures
   82         Add a hack to the optimizer to try to catch certain optimizer
   83             loops (should prevent GitHub issue #112)
   84         Show special Linux BPF offsets symbolically in bpf_image() and
   85             bpf_dump()
   86         Added support for ICMPv6 types 1-4 as tokens with names

   98         Redo protocol version negotiation to avoid problems with old
   99             servers (it still works with servers using the old negotiation,

  106         On UN*X, don't have rpcapd tell the client why authentication
  107             failed, so a brute-force attacker can't distinguish between
  108             "unknown user name" and "known user name, wrong password"
  109         Allow rpcapd to rebind more rapidly (GitHub issue #765)

  123         Get rid of Wireless Extensions for turning monitor mode on
  124         Proper memory sync for PACKET_MMAP (may prevent GitHub issue
  125             #898)
  126         Drop support for libnl 1 and 2.
  127         Return error on interface going away, but not if it just went
  128             down but is still present
  129         Set socket protocol only after packet ring configured,
  130             reducing bogus packet drop reports
  131         Get ifdrop stats from sysfs.
  132         When adjusting BPF programs, do not subtract the
  133             SLL[2]_HDR_LEN if the location is negative (special metadata
  134             offset), to preserve references to metadata; see

  653 	Note that poll() works on BPF devices is Snow Leopard
  654 	If an ENXIO or ENETDOWN is received, it may mean the device has
  655 	  gone away.  Deal with it.

  861 Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release
  862 
  863 	New Linux libpcap implementation, which, in 2.2 and later
  864 	kernels, uses PF_PACKET sockets and supports kernel packet
  865 	filtering (if compiled into the kernel), and supports the "any"
  866 	device for capturing on all interfaces.  Cleans up promiscuous
  867 	mode better on pre-2.2 kernels, and has various other fixes
  868 	(handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
  869 	doesn't show duplicate packets on loopback interface, etc.).
  870 
  871 	Fixed HP-UX libpcap implementation to correctly get the PPA for
  872 	an interface, to allow interfaces to be opened by interface name.
  873 
  874 	libpcap savefiles have system-independent link-layer type values
  875 	in the header, rather than sometimes platform-dependent DLT_
  876 	values, to make it easier to exchange capture files between
  877 	different OSes.
  878 
  879 	Non-standard capture files produced by some Linux tcpdumps, e.g.
  880 	the one from Red Hat Linux 6.2 and later, can now be read.
  881 
  882 	Updated autoconf stock files.
  883 
  884 	Filter expressions can filter on VLAN IDs and various OSI
  885 	protocols, and work on Token Ring (with non-source-routed
  886 	packets).
  887 
  888 	"pcap_open_dead()" added to allow compiling filter expressions
  889 	to pcap code without opening a capture device or capture file.
  890 
  891 	Header files fixed to allow use in C++ programs.
  892 
  893 	Removed dependency on native headers for packet layout.
  894 	Removed Linux specific headers that were shipped.
  895 
  896 	Security fixes: Strcpy replaced with strlcpy, sprintf replaced
  897 	with snprintf.
  898 
  899 	Fixed bug that could cause subsequent "pcap_compile()"s to fail
  900 	erroneously after one compile failed.
  901 
  902 	Assorted other bug fixes.
  903 
  904 	README.aix and README.linux files added to describe
  905 	platform-specific issues.
  906 
  907 	"getifaddrs()" rather than SIOCGIFCONF used, if available.

  917 
  918 Assar Westerlund  <assar@sics.se>
  919 - Building outside the source code tree fixed.
  920 - Changed to write out time stamps with 32-bit seconds and microseconds

  924   the list of interfaces is read as necessary in order to hold the
  925   entire list.
  926 
  927 Greg Troxel <gdt@ir.bbn.com>
  928 - Added a new "pcap_compile_nopcap()", which lets you compile a filter

  999   timeouts.
 1000 
 1001 - Changed ISLOOPBACK() macro when IFF_LOOPBACK isn't available to check
 1002   for "lo" followed by an eos or digit (newer versions of Linux
 1003   apparently call the loopback "lo" instead of "lo0").
 1004 
 1005 - Fixed Linux networking include files to use ints instead of longs to
 1006   avoid problems with 64 bit longs on the alpha. Thanks to Cristian
