06/19/2001	When dropping root, also set up supplementary groups
		properly.  On Linux, when sending RA's, check that the
		interface has joined all-routers multicast group.  Add a few
		RFC2461 MUST sanity checks when receiving datagrams.  Clean
		out non-EUI64 addressing scheme and other minor bits.
		(Pekka Savola)

04/28/2001	Misc cleanup and bugfixes, automake support.

03/28/2001	Grammar cleanup. Integrated 6to4 support through
		"Base6to4Interface" option in prefix configuration. Signal
		handling fixed by blocking on select() rather than recvmsg()
		so SIGTERM/HUP take effect immediately now. (Nathan Lutchansky)

03/27/2001	Security fixes: close stdin/out and chdir("/") via
		daemon() to prevent possible exploits, and a flag to allow
		radvd to set[ug]id to an unprivileged user (from Pekka Savola).

02/01/2001	scope_id is not supported in glibc2.1. So it is now
		compiled conditionally.

01/31/2001	Add CC variable to Makefile. Fix bug with IPV6_ADD_MEMBERSHIP
		handling. Set scope_id when sending packets.

12/02/2000	man pages update, rewritten pid file handling, rewritten
		signal handling (SIGHUP and SIGTERM), gcc warnings cleanup,
		new radvdump option -f: print received RAs in config file
		format (by Marko)

11/19/2000	integrated the last two change entries into the main source
		(patches by Marko Myllynen), fixed bug in log.c, fixed file
		description leak in readin_config, rewrote code in timer.c,
		updated man pages again (from Marko Myllynen, too), PID
		file support (patch from Marko Myllynen, based on a patch
		from Tommi.Komulainen@iki.fi)

15/08/2000	RFC 2461 updates, Mobile IPv6 extensions added

14/07/2000 	added RA interval option and modified some default values
		for timers

06/15/99	changed to run with glibc 2.1 on RedHat 6.0.

03/03/98	radvd now joins ipv6-allrouters on Linux.  Fix contributed
		by A.N.Kuznetsov <kuznet@ms2.inr.ac.ru>.

10/23/97	radvd will now accept any prefix length in its config
		file but will warn about unusual ones

10/19/97	removed backwards compatibility code in recv.c.
		IPV6_HOPLIMIT support is now assumed to exist.

10/19/97	fixed alignment problems in recv.c and send.c.

10/16/97	the Makefile install target now uses mkinstalldirs.

10/16/97	changed all u_int*_t to uint*_t for better POSIX
		compliance and portability. Needs 2.1.57-CVS or glibc.
		BSD seems to need patches.

10/16/97	more intelligent configure; tries to figure out
		where the IPv6 libraries and inclues are (if not in
		the standard places). Searches in /usr/inet6 and /usr/ipv6.

10/15/97	integrated small patches for glibc and BSD from Craig and
		Philip

09/14/97	EUI-64 "support"

09/01/97	centralized all includes into includes.h for easier
		maintainance

08/25/97	changed all occurences of IPV6_TXINFO/IPV6_RXINFO
		to IPV6_PKTINFO

08/25/97	removed some compatibility stuff for older Linux kernels

03/17/97	changed linux/if_arp.h to net/if_arp.h in device-linux.c
		and configure.in (for glibc compatibility)

03/17/97	integrated patch from Philip Blundell <pjb27@cam.ac.uk>
		into configure.in to check for inet_* in libc first and
		then for libinet6 (for glibc compatibility).

03/16/97	corrected small error in radvd.conf(5) man page and other
		small changes

03/16/97	removed linklocal.c source file from the distribution
		because it wasn't used anymore

03/16/97	added html version of the INTRO, removed ascii version.

02/12/97	missing directories are now created on make install

01/19/97	now also the rest of a line followed by a '#' is treated
		as a comment in the config file

01/16/97	added IPPROTO_IPV6/IPV6_HOPLIMIT support, so now incoming
		RS' and RAs are checked if there hoplimit is 255 (on Linux
		this only works with kernel version 2.1.21 and above)

01/15/97	lots of portability cleanups; radvd is now using autoconf
		for automatic configuration; removed support for the
		in. prefix

01/05/97	integrated BSD 4.4 patches from Craig <cmetz@inner.net>

12/21/96	release of version 0.3

12/15/96	the AdvSendAdvert flag works now

12/14/96	added radvdump, dumps all received RAs in a human
		readable form	

12/13/96	rewrote radvd to use new advanced API headers

12/08/96	added radvd.conf(5) man page

12/03/96	changed RAW_CHECKSUM to IPV6_CHECKSUM for kernels
		2.1.14 and above

11/24/96	added checking of received RAs according to RFC 1970

11/20/96	rewrote the default handling, now it should conform
		to RFC 1970

11/17/96	release of version 0.2
	
11/17/96	added -h (--help) and -f (--facility) option

11/17/96	added setsockopt(..., SOL_IPV6, IPV6_MULTICAST_HOPS), so
	 	that radvd works for kernel versions >2.1.7 (without this
	 	you get "NDISC: fake router advertisment received" on your
	 	hosts)
	
11/17/96	added a man page for radvd(8)

11/17/96	some minor filename changes

11/13/96	first release of this version of in.radvd (0.1)
