Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release

	New Linux libpcap implementation, which, in 2.2 and later

	kernels, uses PF_PACKET sockets and supports kernel packet

	filtering (if compiled into the kernel), and supports the "any"

	device for capturing on all interfaces.  Cleans up promiscuous

	mode better on pre-2.2 kernels, and has various other fixes

	(handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,

	doesn't show duplicate packets on loopback interface, etc.).

	Fixed HP-UX libpcap implementation to correctly get the PPA for

	an interface, to allow interfaces to be opened by interface name.

	libpcap savefiles have system-independent link-layer type values

	in the header, rather than sometimes platform-dependent DLT_

	values, to make it easier to exchange capture files between

	different OSes.

	Non-standard capture files produced by some Linux tcpdumps, e.g.

	the one from Red Hat Linux 6.2 and later, can now be read.

	Updated autoconf stock files.

	Filter expressions can filter on VLAN IDs and various OSI

	protocols, and work on Token Ring (with non-source-routed

	packets).

	"pcap_open_dead()" added to allow compiling filter expressions

	to pcap code without opening a capture device or capture file.

	Header files fixed to allow use in C++ programs.

	Removed dependancy on native headers for packet layout.

	Removed Linux specific headers that were shipped.

	Security fixes: Strcpy replaced with strlcpy, sprintf replaced

	with snprintf.

	Fixed bug that could cause subsequent "pcap_compile()"s to fail

	erroneously after one compile failed.

	Assorted other bug fixes.

	README.aix and README.linux files added to describe

	platform-specific issues.

	"getifaddrs()" rather than SIOCGIFCONF used, if available.

itojun@iijlab.net

- Brought in KAME IPv6/IPsec bpf compiler.

- Fixes for NetBSD.

  and changes to work around different BSDs having different DLT_ types

  with the same numeric value.

Assar Westerlund  <assar@sics.se>

- Building outside the source code tree fixed.

- Changed to write out time stamps with 32-bit seconds and microseconds

  fields, regardless of whether those fields are 32 bits or 64 bits in

  the OS's native "struct timeval".

- Changed "pcap_lookupdev()" to dynamically grow the buffer into which

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

  entire list.

Greg Troxel <gdt@ir.bbn.com>

- Added a new "pcap_compile_nopcap()", which lets you compile a filter

  expression into a BPF program without having an open live capture or

  capture file.
