1094 Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release
1096 New Linux libpcap implementation, which, in 2.2 and later
1097 kernels, uses PF_PACKET sockets and supports kernel packet
1098 filtering (if compiled into the kernel), and supports the "any"
1099 device for capturing on all interfaces. Cleans up promiscuous
1100 mode better on pre-2.2 kernels, and has various other fixes
1101 (handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
1102 doesn't show duplicate packets on loopback interface, etc.).
1104 Fixed HP-UX libpcap implementation to correctly get the PPA for
1105 an interface, to allow interfaces to be opened by interface name.
1107 libpcap savefiles have system-independent link-layer type values
1108 in the header, rather than sometimes platform-dependent DLT_
1109 values, to make it easier to exchange capture files between
1112 Non-standard capture files produced by some Linux tcpdumps, e.g.
1113 the one from Red Hat Linux 6.2 and later, can now be read.
1115 Updated autoconf stock files.
1117 Filter expressions can filter on VLAN IDs and various OSI
1118 protocols, and work on Token Ring (with non-source-routed
1121 "pcap_open_dead()" added to allow compiling filter expressions
1122 to pcap code without opening a capture device or capture file.
1124 Header files fixed to allow use in C++ programs.
1126 Removed dependency on native headers for packet layout.
1127 Removed Linux specific headers that were shipped.
1129 Security fixes: Strcpy replaced with strlcpy, sprintf replaced
1132 Fixed bug that could cause subsequent "pcap_compile()"s to fail
1133 erroneously after one compile failed.
1135 Assorted other bug fixes.
1137 README.aix and README.linux files added to describe
1138 platform-specific issues.
1140 "getifaddrs()" rather than SIOCGIFCONF used, if available.

1145 - Brought in KAME IPv6/IPsec bpf compiler.
1147 - Support added for OpenBSD DLT_LOOP and BSD/OS DLT_C_HDLC (Cisco HDLC),

1157 the list of interfaces is read as necessary in order to hold the

1234 - Changed ISLOOPBACK() macro when IFF_LOOPBACK isn't available to check

1236 apparently call the loopback "lo" instead of "lo0").
1238 - Fixed Linux networking include files to use ints instead of longs to
1239 avoid problems with 64 bit longs on the alpha. Thanks to Cristian

1324 v0.1 Fri Apr 28 18:11:03 PDT 1995
1326 - Fixed compiler and optimizer bugs. The BPF filter engine uses unsigned

1382 - Fix two bugs related to the Solaris pre-5.3.2 bufmod bug; handle
1383 savefiles that have more than snapshot bytes of data in them (so we

1386 - Added checkioctl which is used with gcc to check that the
1387 "fixincludes" script has been run.
1389 v0.0.3 Tue Oct 18 18:13:46 PDT 1994
