1095 Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release
1097 New Linux libpcap implementation, which, in 2.2 and later
1098 kernels, uses PF_PACKET sockets and supports kernel packet
1099 filtering (if compiled into the kernel), and supports the "any"
1100 device for capturing on all interfaces. Cleans up promiscuous
1101 mode better on pre-2.2 kernels, and has various other fixes
1102 (handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
1103 doesn't show duplicate packets on loopback interface, etc.).
1105 Fixed HP-UX libpcap implementation to correctly get the PPA for
1106 an interface, to allow interfaces to be opened by interface name.
1108 libpcap savefiles have system-independent link-layer type values
1109 in the header, rather than sometimes platform-dependent DLT_
1110 values, to make it easier to exchange capture files between
1113 Non-standard capture files produced by some Linux tcpdumps, e.g.
1114 the one from Red Hat Linux 6.2 and later, can now be read.
1116 Updated autoconf stock files.
1118 Filter expressions can filter on VLAN IDs and various OSI
1119 protocols, and work on Token Ring (with non-source-routed
1122 "pcap_open_dead()" added to allow compiling filter expressions
1123 to pcap code without opening a capture device or capture file.
1125 Header files fixed to allow use in C++ programs.
1127 Removed dependency on native headers for packet layout.
1128 Removed Linux specific headers that were shipped.
1130 Security fixes: Strcpy replaced with strlcpy, sprintf replaced
1133 Fixed bug that could cause subsequent "pcap_compile()"s to fail
1134 erroneously after one compile failed.
1136 Assorted other bug fixes.
1138 README.aix and README.linux files added to describe
1139 platform-specific issues.
1141 "getifaddrs()" rather than SIOCGIFCONF used, if available.

1148 - Support added for OpenBSD DLT_LOOP and BSD/OS DLT_C_HDLC (Cisco HDLC),

1235 - Changed ISLOOPBACK() macro when IFF_LOOPBACK isn't available to check

1237 apparently call the loopback "lo" instead of "lo0").
1239 - Fixed Linux networking include files to use ints instead of longs to
1240 avoid problems with 64 bit longs on the alpha. Thanks to Cristian

1325 v0.1 Fri Apr 28 18:11:03 PDT 1995
1327 - Fixed compiler and optimizer bugs. The BPF filter engine uses unsigned

1387 - Added checkioctl which is used with gcc to check that the
1388 "fixincludes" script has been run.
1390 v0.0.3 Tue Oct 18 18:13:46 PDT 1994
