Summary for 3.8.3 release Fixed minor problem in gencode.c that would appear on 64-bit platforms. Version number is now sane. Mon. March 29, 2004. mcr@sandelman.ottawa.on.ca. Summary for 3.8.2 release updates for autoconf 2.5 fixes for ppp interfaces for freebsd 4.1 pcap gencode can generate code for 802.11, IEEE1394, and pflog. Wed. November 12, 2003. mcr@sandelman.ottawa.on.ca. Summary for 0.8 release added pcap_findalldevs() Win32 patches from NetGroup, Politecnico di Torino (Italy) OpenBSD pf, DLT_PFLOG added Many changes to ATM support. lookup pcap_lookupnet() Added DLT_ARCNET_LINUX, DLT_ENC, DLT_IEEE802_11_RADIO, DLT_SUNATM, DLT_IP_OVER_FC, DLT_FRELAY, others. Sigh. More AIX wonderfulness. Document updates. Changes to API: pcap_next_ex(), pcap_breakloop(), pcap_dump_flush(), pcap_list_datalinks(), pcap_set_datalink(), pcap_lib_version(), pcap_datalink_val_to_name(), pcap_datalink_name_to_val(), new error returns. Tuesday, February 25, 2003. fenner@research.att.com. 0.7.2 release Support link types that use 802.2 always, never, and sometimes. Don't decrease the size of the BPF buffer from the default. Support frame relay. Handle 32-bit timestamps in DLPI, and pass the right buffer size. Handle Linux systems with modern kernel but without SOL_PACKET in the userland headers. Linux support for ARPHRD_RAWHDLC. Handle 32-bit timestamps in snoop. Support eg (Octane/O2xxx/O3xxx Gigabit) devices. Add new reserved DLT types. Monday October 23, 2001. mcr@sandelman.ottawa.on.ca. Summary for 0.7 release Added pcap_findalldevs() call to get list of interfaces in a MI way. pcap_stats() has been documented as to what its counters mean on each platform. Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release New Linux libpcap implementation, which, in 2.2 and later kernels, uses PF_PACKET sockets and supports kernel packet filtering (if compiled into the kernel), and supports the "any" device for capturing on all interfaces. Cleans up promiscuous mode better on pre-2.2 kernels, and has various other fixes (handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better, doesn't show duplicate packets on loopback interface, etc.). Fixed HP-UX libpcap implementation to correctly get the PPA for an interface, to allow interfaces to be opened by interface name. libpcap savefiles have system-independent link-layer type values in the header, rather than sometimes platform-dependent DLT_ values, to make it easier to exchange capture files between different OSes. Non-standard capture files produced by some Linux tcpdumps, e.g. the one from Red Hat Linux 6.2 and later, can now be read. Updated autoconf stock files. Filter expressions can filter on VLAN IDs and various OSI protocols, and work on Token Ring (with non-source-routed packets). "pcap_open_dead()" added to allow compiling filter expressions to pcap code without opening a capture device or capture file. Header files fixed to allow use in C++ programs. Removed dependancy on native headers for packet layout. Removed Linux specific headers that were shipped. Security fixes: Strcpy replaced with strlcpy, sprintf replaced with snprintf. Fixed bug that could cause subsequent "pcap_compile()"s to fail erroneously after one compile failed. Assorted other bug fixes. README.aix and README.linux files added to describe platform-specific issues. "getifaddrs()" rather than SIOCGIFCONF used, if available. v0.5 Sat Jun 10 11:09:15 PDT 2000 itojun@iijlab.net - Brought in KAME IPv6/IPsec bpf compiler. - Fixes for NetBSD. - Support added for OpenBSD DLT_LOOP and BSD/OS DLT_C_HDLC (Cisco HDLC), and changes to work around different BSDs having different DLT_ types with the same numeric value. Assar Westerlund - Building outside the source code tree fixed. - Changed to write out time stamps with 32-bit seconds and microseconds fields, regardless of whether those fields are 32 bits or 64 bits in the OS's native "struct timeval". - Changed "pcap_lookupdev()" to dynamically grow the buffer into which the list of interfaces is read as necessary in order to hold the entire list. Greg Troxel - Added a new "pcap_compile_nopcap()", which lets you compile a filter expression into a BPF program without having an open live capture or capture file. v0.4 Sat Jul 25 12:40:09 PDT 1998 - Fix endian problem with DLT_NULL devices. From FreeBSD via Bill Fenner (fenner@parc.xerox.com) - Fix alignment problem with FDDI under DLPI. This was causing core dumps under Solaris. - Added configure options to disable flex and bison.

Also added options to disable gcc and to force a particular packet capture type. - Added support for Fore ATM interfaces (qaa and fa) under IRIX. Thanks to John Hawkinson (jhawk@mit.edu) - Change Linux PPP and SLIP to use DLT_RAW since the kernel does not supply any "link layer" data. - Change Linux to use SIOCGIFHWADDR ioctl to determine link layer type.

Reported reported by Eric Jacksch (jacksch@tenebris.ca) - Fixed bug in pcap_dispatch() that kept it from returning on packet timeouts. - Changed ISLOOPBACK() macro when IFF_LOOPBACK isn't available to check for "lo" followed by an eos or digit (newer versions of Linux apparently call the loopback "lo" instead of "lo0"). - Fixed Linux networking include files to use ints instead of longs to avoid problems with 64 bit longs on the alpha.

Eric Townsend (jet@abulafia.genmagic.com). - Hack around deficiency in Ultrix's make. - Fix two bugs related to the Solaris pre-5.3.2 bufmod bug; handle savefiles that have more than snapshot bytes of data in them (so we can read old savefiles) and avoid writing such files. - Added checkioctl which is used with gcc to check that the "fixincludes" script has been run. v0.0.3 Tue Oct 18 18:13:46 PDT 1994 - Fixed configure to test for snoop before dlpi to avoid problems under IRIX 5.
