Summary for 0.6 release 169 170 New Linux libpcap implementation, which, in 2.2 and later 171 kernels, uses PF_PACKET sockets and supports kernel packet 172 filtering (if compiled into the kernel), and supports the "any" 173 device for capturing on all interfaces. Cleans up promiscuous 174 mode better on pre-2.2 kernels, and has various other fixes 175 (handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better, 176 doesn't show duplicate packets on loopback interface, etc.). 177 178 Fixed HP-UX libpcap implementation to correctly get the PPA for 179 an interface, to allow interfaces to be opened by interface name. 180 181 libpcap savefiles have system-independent link-layer type values 182 in the header, rather than sometimes platform-dependent DLT_ 183 values, to make it easier to exchange capture files between 184 different OSes. 185 186 Non-standard capture files produced by some Linux tcpdumps, e.g. 187 the one from Red Hat Linux 6.2 and later, can now be read. 188 189 Updated autoconf stock files. 190 191 Filter expressions can filter on VLAN IDs and various OSI 192 protocols, and work on Token Ring (with non-source-routed 193 packets). 194 195 "pcap_open_dead()" added to allow compiling filter expressions 196 to pcap code without opening a capture device or capture file. 197 198 Header files fixed to allow use in C++ programs. 199 200 Removed dependancy on native headers for packet layout. 201 Removed Linux specific headers that were shipped. 202 203 Security fixes: Strcpy replaced with strlcpy, sprintf replaced 204 with snprintf. 205 206 Fixed bug that could cause subsequent "pcap_compile()"s to fail 207 erroneously after one compile failed. 208 209 Assorted other bug fixes. 210 211 README.aix and README.linux files added to describe 212 platform-specific issues. 213 214 "getifaddrs()" rather than SIOCGIFCONF used, if available. 215 216v0.5 Sat Jun 10 11:09:15 PDT 2000 217 218itojun@iijlab.net 219- Brought in KAME IPv6/IPsec bpf compiler. 220- Fixes for NetBSD. 221- Support added for OpenBSD DLT_LOOP and BSD/OS DLT_C_HDLC (Cisco HDLC), 222 and changes to work around different BSDs having different DLT_ types 223 with the same numeric value. 224 225Assar Westerlund <assar@sics.se> 226- Building outside the source code tree fixed. 227- Changed to write out time stamps with 32-bit seconds and microseconds 228 fields, regardless of whether those fields are 32 bits or 64 bits in 229 the OS's native "struct timeval". 230- Changed "pcap_lookupdev()" to dynamically grow the buffer into which 231 the list of interfaces is read as necessary in order to hold the 232 entire list. 233 234Greg Troxel <gdt@ir.bbn.com> 235- Added a new "pcap_compile_nopcap()", which lets you compile a filter 236 expression into a BPF program without having an open live capture or 237 capture file. 238 239v0.4 Sat Jul 25 12:40:09 PDT 1998 240 241- Fix endian problem with DLT_NULL devices. From FreeBSD via Bill 242 Fenner (fenner@parc.xerox.com) 243 244- Fix alignment problem with FDDI under DLPI. This was causing core 245 dumps under Solaris. 246 247- Added configure options to disable flex and bison. Resulted from a 248 bug report by barnett@grymoire.crd.ge.com (Bruce Barnett). Also added 249 options to disable gcc and to force a particular packet capture type. 250 251- Added support for Fore ATM interfaces (qaa and fa) under IRIX. Thanks 252 to John Hawkinson (jhawk@mit.edu) 253 254- Change Linux PPP and SLIP to use DLT_RAW since the kernel does not 255 supply any "link layer" data. 256 257- Change Linux to use SIOCGIFHWADDR ioctl to determine link layer type. 258 Thanks to Thomas Sailer (sailer@ife.ee.ethz.ch) 259 260- Change IRIX PPP to use DLT_RAW since the kernel does not supply any 261 "link layer" data. 262 263- Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header 264 formats. 265 266- Added some new SGI snoop interface types.
