Summary for 0.6 release 7256889Sfenner 7375107Sfenner New Linux libpcap implementation, which, in 2.2 and later 7475107Sfenner kernels, uses PF_PACKET sockets and supports kernel packet 7575107Sfenner filtering (if compiled into the kernel), and supports the "any" 7675107Sfenner device for capturing on all interfaces. Cleans up promiscuous 7775107Sfenner mode better on pre-2.2 kernels, and has various other fixes 7875107Sfenner (handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better, 7975107Sfenner doesn't show duplicate packets on loopback interface, etc.). 8056889Sfenner 8175107Sfenner Fixed HP-UX libpcap implementation to correctly get the PPA for 8275107Sfenner an interface, to allow interfaces to be opened by interface name. 8375107Sfenner 8475107Sfenner libpcap savefiles have system-independent link-layer type values 8575107Sfenner in the header, rather than sometimes platform-dependent DLT_ 8675107Sfenner values, to make it easier to exchange capture files between 8775107Sfenner different OSes. 8875107Sfenner 8975107Sfenner Non-standard capture files produced by some Linux tcpdumps, e.g. 9075107Sfenner the one from Red Hat Linux 6.2 and later, can now be read. 9175107Sfenner 9275107Sfenner Updated autoconf stock files. 9375107Sfenner 9475107Sfenner Filter expressions can filter on VLAN IDs and various OSI 9575107Sfenner protocols, and work on Token Ring (with non-source-routed 9675107Sfenner packets). 9775107Sfenner 9875107Sfenner "pcap_open_dead()" added to allow compiling filter expressions 9975107Sfenner to pcap code without opening a capture device or capture file. 10075107Sfenner 10175107Sfenner Header files fixed to allow use in C++ programs. 10275107Sfenner 10375107Sfenner Removed dependancy on native headers for packet layout. 10475107Sfenner Removed Linux specific headers that were shipped. 10575107Sfenner 10675107Sfenner Security fixes: Strcpy replaced with strlcpy, sprintf replaced 10775107Sfenner with snprintf. 10875107Sfenner 10975107Sfenner Fixed bug that could cause subsequent "pcap_compile()"s to fail 11075107Sfenner erroneously after one compile failed. 11175107Sfenner 11275107Sfenner Assorted other bug fixes. 11375107Sfenner 11475107Sfenner README.aix and README.linux files added to describe 11575107Sfenner platform-specific issues. 11675107Sfenner 11775107Sfenner "getifaddrs()" rather than SIOCGIFCONF used, if available. 11875107Sfenner 11975107Sfennerv0.5 Sat Jun 10 11:09:15 PDT 2000 12075107Sfenner 12175107Sfenneritojun@iijlab.net 12275107Sfenner- Brought in KAME IPv6/IPsec bpf compiler. 12375107Sfenner- Fixes for NetBSD. 12475107Sfenner- Support added for OpenBSD DLT_LOOP and BSD/OS DLT_C_HDLC (Cisco HDLC), 12575107Sfenner and changes to work around different BSDs having different DLT_ types 12675107Sfenner with the same numeric value. 12775107Sfenner 12875107SfennerAssar Westerlund <assar@sics.se> 12975107Sfenner- Building outside the source code tree fixed. 13075107Sfenner- Changed to write out time stamps with 32-bit seconds and microseconds 13175107Sfenner fields, regardless of whether those fields are 32 bits or 64 bits in 13275107Sfenner the OS's native "struct timeval". 13375107Sfenner- Changed "pcap_lookupdev()" to dynamically grow the buffer into which 13475107Sfenner the list of interfaces is read as necessary in order to hold the 13575107Sfenner entire list. 13675107Sfenner 13775107SfennerGreg Troxel <gdt@ir.bbn.com> 13875107Sfenner- Added a new "pcap_compile_nopcap()", which lets you compile a filter 13975107Sfenner expression into a BPF program without having an open live capture or 14075107Sfenner capture file. 141162012Ssam 14239291Sfennerv0.4 Sat Jul 25 12:40:09 PDT 1998 14339291Sfenner 14439291Sfenner- Fix endian problem with DLT_NULL devices.
