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 dependency 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 <assar@sics.se> - 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 <gdt@ir.bbn.com> - 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.
