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.).
178 Fixed HP-UX libpcap implementation to correctly get the PPA for
179 an interface, to allow interfaces to be opened by interface name.
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
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.
189 Updated autoconf stock files.
191 Filter expressions can filter on VLAN IDs and various OSI
192 protocols, and work on Token Ring (with non-source-routed
195 "pcap_open_dead()" added to allow compiling filter expressions
196 to pcap code without opening a capture device or capture file.
198 Header files fixed to allow use in C++ programs.
200 Removed dependancy on native headers for packet layout.
201 Removed Linux specific headers that were shipped.
203 Security fixes: Strcpy replaced with strlcpy, sprintf replaced
206 Fixed bug that could cause subsequent "pcap_compile()"s to fail
207 erroneously after one compile failed.
209 Assorted other bug fixes.
211 README.aix and README.linux files added to describe
212 platform-specific issues.
214 "getifaddrs()" rather than SIOCGIFCONF used, if available.

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