529 Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release
531 New Linux libpcap implementation, which, in 2.2 and later
532 kernels, uses PF_PACKET sockets and supports kernel packet
533 filtering (if compiled into the kernel), and supports the "any"
534 device for capturing on all interfaces. Cleans up promiscuous
535 mode better on pre-2.2 kernels, and has various other fixes
536 (handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
537 doesn't show duplicate packets on loopback interface, etc.).
539 Fixed HP-UX libpcap implementation to correctly get the PPA for
540 an interface, to allow interfaces to be opened by interface name.
542 libpcap savefiles have system-independent link-layer type values
543 in the header, rather than sometimes platform-dependent DLT_
544 values, to make it easier to exchange capture files between
547 Non-standard capture files produced by some Linux tcpdumps, e.g.
548 the one from Red Hat Linux 6.2 and later, can now be read.
550 Updated autoconf stock files.
552 Filter expressions can filter on VLAN IDs and various OSI
553 protocols, and work on Token Ring (with non-source-routed
556 "pcap_open_dead()" added to allow compiling filter expressions
557 to pcap code without opening a capture device or capture file.
559 Header files fixed to allow use in C++ programs.
561 Removed dependancy on native headers for packet layout.
562 Removed Linux specific headers that were shipped.
564 Security fixes: Strcpy replaced with strlcpy, sprintf replaced
567 Fixed bug that could cause subsequent "pcap_compile()"s to fail
568 erroneously after one compile failed.
570 Assorted other bug fixes.
572 README.aix and README.linux files added to describe
573 platform-specific issues.
575 "getifaddrs()" rather than SIOCGIFCONF used, if available.

592 the list of interfaces is read as necessary in order to hold the
595 Greg Troxel <gdt@ir.bbn.com>
