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.

652 errors, and check for the errors in question.
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.
656 For BPF, raise the default capture buffer size to from 32k to 512k

712 can print better diagnostic information
713 Return PCAP_ERROR_PERM_DENIED if we don't have permission to open a device, so
714 applications can tell the user they need to go play with permissions

861 Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release
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.).
871 Fixed HP-UX libpcap implementation to correctly get the PPA for
872 an interface, to allow interfaces to be opened by interface name.
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.
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.
882 Updated autoconf stock files.
884 Filter expressions can filter on VLAN IDs and various OSI
885 protocols, and work on Token Ring (with non-source-routed
886 packets).
888 "pcap_open_dead()" added to allow compiling filter expressions
889 to pcap code without opening a capture device or capture file.
891 Header files fixed to allow use in C++ programs.
893 Removed dependency on native headers for packet layout.
894 Removed Linux specific headers that were shipped.
896 Security fixes: Strcpy replaced with strlcpy, sprintf replaced
897 with snprintf.
899 Fixed bug that could cause subsequent "pcap_compile()"s to fail
900 erroneously after one compile failed.
902 Assorted other bug fixes.
904 README.aix and README.linux files added to describe
905 platform-specific issues.
907 "getifaddrs()" rather than SIOCGIFCONF used, if available.
909 v0.5 Sat Jun 10 11:09:15 PDT 2000
911 itojun@iijlab.net
912 - Brought in KAME IPv6/IPsec bpf compiler.
913 - Fixes for NetBSD.
914 - Support added for OpenBSD DLT_LOOP and BSD/OS DLT_C_HDLC (Cisco HDLC),
915 and changes to work around different BSDs having different DLT_ types
916 with the same numeric value.
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
921 fields, regardless of whether those fields are 32 bits or 64 bits in
922 the OS's native "struct timeval".
923 - Changed "pcap_lookupdev()" to dynamically grow the buffer into which
924 the list of interfaces is read as necessary in order to hold the
925 entire list.
927 Greg Troxel <gdt@ir.bbn.com>
928 - Added a new "pcap_compile_nopcap()", which lets you compile a filter
929 expression into a BPF program without having an open live capture or
930 capture file.
932 v0.4 Sat Jul 25 12:40:09 PDT 1998
934 - Fix endian problem with DLT_NULL devices. From FreeBSD via Bill
935 Fenner (fenner@parc.xerox.com)

942 options to disable gcc and to force a particular packet capture type.
944 - Added support for Fore ATM interfaces (qaa and fa) under IRIX. Thanks
945 to John Hawkinson (jhawk@mit.edu)
947 - Change Linux PPP and SLIP to use DLT_RAW since the kernel does not
948 supply any "link layer" data.
950 - Change Linux to use SIOCGIFHWADDR ioctl to determine link layer type.
951 Thanks to Thomas Sailer (sailer@ife.ee.ethz.ch)

963 Richard Allen (ra@hp.is) and Steinar Haug (sthaug@nethelp.no)
965 - Fddi supports broadcast as reported by Jeff Macdonald
966 (jeff@iacnet.com). Also correct ieee802 and arcnet.
968 - Determine Linux pcap buffer size at run time or else it might not be
969 big enough for some interface types (e.g. FDDI). Thanks to Jes
970 Sorensen (Jes.Sorensen@cern.ch)

974 - Document promisc argument to pcap_open_live(). Reported by Ian Marsh

985 (rroberts@muller.com)
987 - Fixed an uninitialized memory reference found by Kent Vander Velden

999 timeouts.
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").

1006 avoid problems with 64 bit longs on the alpha. Thanks to Cristian

1102 don't support live package capture. This feature resulting from a
1103 request from Jan van Oorschot (j.p.m.voorschot@et.tudelft.nl).
1105 - Make bpf_compile() reentrant. Fix thanks to Pascal Hennequin
1106 (Pascal.Hennequin@hugo.int-evry.fr).

1139 - Change configuration to not use gcc v2 flags with gcc v1.
1141 - Fixed a bug in pcap_next(); if pcap_dispatch() returns 0, pcap_next()
1142 should also return 0. Thanks to Richard Stevens (rstevens@noao.edu).

1149 - Fix two bugs related to the Solaris pre-5.3.2 bufmod bug; handle
1150 savefiles that have more than snapshot bytes of data in them (so we
1151 can read old savefiles) and avoid writing such files.
1153 - Added checkioctl which is used with gcc to check that the
1154 "fixincludes" script has been run.
1156 v0.0.3 Tue Oct 18 18:13:46 PDT 1994
