157 New Linux libpcap implementation, which, in 2.2 and later
158 kernels, uses PF_PACKET sockets and supports kernel packet
159 filtering (if compiled into the kernel), and supports the "any"
160 device for capturing on all interfaces. Cleans up promiscuous
161 mode better on pre-2.2 kernels, and has various other fixes
162 (handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
163 doesn't show duplicate packets on loopback interface, etc.).
165 Fixed HP-UX libpcap implementation to correctly get the PPA for
166 an interface, to allow interfaces to be opened by interface name.
168 libpcap savefiles have system-independent link-layer type values
169 in the header, rather than sometimes platform-dependent DLT_
170 values, to make it easier to exchange capture files between
173 Non-standard capture files produced by some Linux tcpdumps, e.g.
174 the one from Red Hat Linux 6.2 and later, can now be read.
176 Updated autoconf stock files.
178 Filter expressions can filter on VLAN IDs and various OSI
179 protocols, and work on Token Ring (with non-source-routed
182 "pcap_open_dead()" added to allow compiling filter expressions
183 to pcap code without opening a capture device or capture file.
185 Header files fixed to allow use in C++ programs.
187 Removed dependancy on native headers for packet layout.
188 Removed Linux specific headers that were shipped.
190 Security fixes: Strcpy replaced with strlcpy, sprintf replaced
193 Fixed bug that could cause subsequent "pcap_compile()"s to fail
194 erroneously after one compile failed.
196 Assorted other bug fixes.
198 README.aix and README.linux files added to describe
199 platform-specific issues.
201 "getifaddrs()" rather than SIOCGIFCONF used, if available.

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