$Id: CHANGES,v 1.97 2010/03/05 12:15:33 psavola Exp $
05/03/2010 Release 1.6.
05/03/2010 Update Redhat spec and init files from Fedora.
28/01/2010 Decrease MSG_SIZE from 4096 to about 1500B. Send buffer
uses a smaller size in order to avoid sending out
fragmented packets, yet being able to receive full-size
frames.
28/01/2010 Keep track of buffer size and exit if the number of
prefixes/routes/etc. would grow too much. Prevent a memory
corruption due to wrong memset. Patches from Jan
Grig, Red Hat bug #554125.
22/01/2010 On BSD use getifaddrs() also in setup_deviceinfo(),
fixes a multiple interfaces problem on NetBSD 5 due to
change in data structures. Patch from Michael Stapelberg.
07/11/2009 Allow radvd.conf prefix, clients, route, and RDNSS options
to be in any order. Patch from Michael Stapelberg.
10/09/2009 Release 1.5.
07/09/2009 Fix infinite loop/segmentation fault problems when cable
plugged out/plugged back in, caused by reload_config()
and subsequent timer list corruption. Slightly modified
patch from Teemu Torma. For more information, see
http://lists.litech.org/pipermail/radvd-devel-l/2009-August/000416.html
07/09/2009 Fix IgnoreIfMissing when cable is unplugged at startup.
Radvd would keep skipping the interface. Patch from
Reuben Hawkins.
25/08/2009 Fix parallel make, from Robert Buchholz / Gentoo.
03/08/2009 Release 1.4. Only restores original behaviour changed in
1.3: RAs were accidentally often unicast to solicitors
instead of being multicast.
07/07/2009 Release 1.3.
24/06/2009 Work around unaligned traps on Alpha, patch from:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=456205
19/06/2009 Fixes and enhancements from Michael Stapelberg. Add a new
'clients' interface definition to allow configuring which
address to send advertisements and accept from. Use
getifaddrs() on BSD because ioctl didn't work on NetBSD 5.
Use int instead of bool to make NetBSD 5 happy.
21/01/2009 Add a workaround for Linux in scenarios where libc is
providing IPV6_RECV(PKTINFO|HOPLIMIT) has renumbered IPV6_PKTINFO,
but kernel doesn't support it yet (<2.6.14). Found out by
Freetz (special thanks to Paul Oranje) and OpenWrt projects.
See the source code and CVS changelog for more.
28/10/2008 Release 1.2.
14/10/2008 Accept virtually any interface name (up to 15 chars) instead of
forcing a specific naming convention. Patch from
Michiel Brandenburg.
If stale radvd.pid file exists, try to overwrite it unless
the specified PID exists, from Fedora (Martin Nagy).
Define _GNU_SOURCE on Linux, otherwise glibc >= 2.8
compilation fails.
Remove -Wconversion from default CFLAGS as it is very noisy.
Fix some warnings, from Jim Paris.
31/03/2008 Update references to RFCs. Give pointer to the "two hour rule".
Decrease the default valid and preferred lifetimes from 30/1
days to 1day/4hours, respectively. See more info at:
http://lists.litech.org/pipermail/radvd-devel-l/2007-October/000282.html
04/02/2008 Release 1.1.
24/01/2008 Implement privilege separation (Linux only) so that
config_interface() works both with a user and root,
even after HUP signal. Work by Jim Paris.
24/01/2008 The old Linux retrans_timer proc value is given in
USER_HZ, not in seconds. Fix that, by Jim Paris.
21/01/2008 Fix stderr+syslog logging crash (on non-i386). Analysis and
patch by Jim Paris (Debian bug #409600).
01/12/2007 Require that interface is also 'RUNNING' instead of just
'UP', except if IgnoreIfMissing is enabled. The reason is
that at least some recent Linux kernels do not generate
link-local addresses before interface is running and as
a result, the startup may fail if network cable is unplugged
in any case.
Note: this could break deployments with some very old
kernels, see more info at:
http://lists.litech.org/pipermail/radvd-devel-l/2007-October/000280.html
25/10/2007 Implement automatically selecting and advertising an
interface address, see radvd.conf(5) for more. Add
a warning about not being able to set interface
variables with non-root user. Relax interface naming
a bit.
25/06/2007 Send prefix, route and RDNSS options (matters if there
are many RDNSS options) in the same order they appear
in the configuration; add support for AdvDefaultLifetime
in radvdump (patches from C. Scott Ananian)
11/01/2006 Release 1.0.
10/09/2006 Perform a static/dynamic code audit; plug some minor
bugs (see CVS changelogs for more information) and
perform minor clean-up.
08/07/2006 Implement MAX_INITIAL_RTR_ADVERT_INTERVAL handling,
patch from Yoshifuji Hideaki / USAGI.
05/23/2006 Unblock SIGALRM signals at startup. Some scripts/programs
seem to run radvd from ALRM-blocked context which breaks
the timers.
05/23/2006 Redefined IgnoreIfMissing: by default, radvd will now
try to reinitialize failed interfaces automatically.
IgnoreIfMissing is still needed if radvd is started when the
interface isn't up, and it also quenches some messages
relating to missing interfaces.
03/29/2006 Implement RDNSS draft, using non-allocated
IANA ND type value 25, by Laurline Provost,
Mickal Gurin, Adrien Clerc, Gaetan Eleouet,
Bahattin Demirplak, Lionel Guilmin (at the
ENSEEIHT, Toulouse)
03/06/2006 Fix the default STDERR+syslog logging methods, so
we don't try to unnecessarily log to STDERR after
forking.
01/18/2006 radvd-0.9.1 did not initialize AdvDefaultLifetime (etc.)
appropriately, unbreak the "clean-up".
01/13/2006 Release 0.9.1.
12/30/2005 Great cleanup of signed/unsigned values, add
-Wall and a number of other warnings to CFLAGS
by default. Do not allow signed values for
HomeAgentPreference anymore.
12/30/2005 Fix a couple of IPv6 Ready Logo Phase-2 IPv6 Core
Protocols Self Test issues, patches from Yoshifuji
Hideaki / USAGI.
11/13/2005 Create a short FAQ in README file.
10/28/2005 Get interface MTU automatically, so that you can
use jumboframes and advertise MTU >1500.
10/19/2005 Release 0.9.
10/18/2005 Transfer sole maintainership of radvd to Pekka Savola.
10/18/2005 Make the radvd.conf syntax dump default
in radvdump and remove the previous default to
reduce code duplication.
09/28/2005 Add NEMO Basic support (RFC3961) and fix default
HomeAgentLifetime, from Ville Nuorvala.
08/18/2005 Implement more robust timer handler, especially
because some Linux kernels don't seem to behave
all that well; see http://lkml.org/lkml/2005/4/29/163.
Based on extensive testing & reports by
Tomasz Grobelny. NB: the bug report was caused by
a bad timer patch in PLD's kernel package, and this
should not occur often with standard kernels.
07/24/2005 Implement a new logging method "stderr_syslog" which is
now also the default. Everything is logged on syslog,
while the most important messages (i.e., start-up failures)
are also logged on stderr.
07/08/2005 Release 0.8.
07/05/2005 Change the more-specific route ND option code
from de-facto '9' to the official '24'. Change
back in defaults.h if you need old behaviour.
07/05/2005 Fix wrongly calculated prefix with Base6to4Interface
on ppc and maybe other big endian arches, from
Debian #301543 by Sam Hathaway.
07/05/2005 Fix Linux-2.6.12-bk4+ error with HUP signal,
from YOSHIFUJI Hideaki / USAGI.
03/29/2005 Merge a part of MIPv6/non-MIPv6 code, make printing
error messages nicer.
03/22/2005 Be a bit more informative about config file parsing
errors.
02/21/2005 Release 0.7.3.
02/19/2005 Fix crash when reloading config with AdvSendAdvert off.
02/15/2005 Merge a few fixes and improvements from USAGI:
- support microsecond scheduling and fix RA intervals
- send zero router lifetime when forwarding is disabled
- use a more flexible inter-RA delay
01/07/2005 Accomodate interface indexes > 9999, from Hagen Fritsch.
12/15/2004 Advertise zero Router Lifetime when shutting down;
implements a SHOULD in RFC2461 section 6.2.5.
10/16/2004 Update Mobile IPv6 to match RFC 3775, from Greg Daley.
08/20/2004 Minor documentation cleanups.
03/09/2004 Implement "IgnoreIfMissing" interface flag, which can be
used on interfaces which aren't enabled when radvd starts
but will later become available (e.g., Bluetooth) --
and then you wish to send HUP to radvd to activate the
configs.
02/21/2004 Further cleanups, to fix autoconf/autoheader problems
with newer toolchain; mostly by Marko Myllynen.
02/20/2004 Clean up a bit: remove old junk from configure.in,
rename "log()" to "flog()" to satisfy newer GCCs,
allow underscores in the interface names (the last two
fixes already committed earlier).
01/19/2004 Make radvd check for forwarding status using procfs on
Linux; needed with 2.6 kernels. Loosely based on
a patch by USAGI.
11/21/2003 Add support for Router Preferences and More Specific
Routes from Markku Savela <msa@burp.tkv.asdf.org>.
NOTE! The specification is not final yet, there will be
changes! (Man page, documentation and radvdump support
by Pekka Savola.)
09/11/2003 When starting up, check if the MAC address is all zero
(could happen e.g. with bridge interfaces with no attached
physical interfaces), and warn if so. For more information,
http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=103469
06/10/2003 When chrooting, check the possible return code
from chdir("/").
03/08/2003 Add patch from MAEDA Naoaki <maeda.naoaki@jp.fujitsu.com>
to discard RS's from the unspecied source address with
link-layer address option, as required by RFC2461.
10/28/2002 Release 0.7.2:
- add support for VLANs (from USAGI)
- make it compile better on newer NetBSD's (NetBSD)
- fix a syntax error in radvd.conf(5) sample documentation
- use IPV6_RECV{HOPLIMIT,PKTINFO} not
IPV6_{HOPLIMIT,PKTINFO} if supported
- (in Red Hat spec file) don't create radvd gid explicitly
- a lot of coding style cleanups
01/16/2002 Release 0.7.1.
01/12/2002 Update config.{guess,sub} from ftp.gnu.org; update INTRO.
Marko Myllynen and Debian bug #115992.
01/02/2002 Ensure NULL-termination with strncpy.
12/31/2001 Radvdump fixes: eliminate a warning of Prefix Information
sections with '-d -f'; add a note that
{Min,Max}RtrAdvInterval cannot be obtained with '-f';
implement '-e' to be used with '-f' which omits all
advertised default settings. Mostly by Marko Myllynen.
12/28/2001 Small cleanups. AdvSendAdvert is implicitly off by
default. Check configuration file permissions; must
not be writable by others, and if non-root,
not by self/own group. By Marko Myllynen.
12/21/2001 Check via sysctl that IPv6 forwarding is enabled;
exit unless debugging is enabled. Triggered by
Marko Myllynen.
11/22/2001 MinRtrAdvInterval for MIPv6 is 0.05 seconds, not 0.5.
(Note: untested).
11/20/2001 Rework BSD device memory management a bit, minor cleanups.
Version bumped to 0.7.0.
11/14/2001 Maintainership of radvd transferred from Lars Fenneberg
to Pekka Savola and Nathan Lutchansky. Lars' CVS
repository adopted, and changes merged from the -pX
branch.
08/29/2001 Minor change for NetBSD 1.5.1 compatibility.
(Nathan Lutchansky)
07/20/2001 Support for non-multicast links, like ISATAP.
(Nathan Lutchansky)
07/03/2001 Minimum MTU has been changed to 1280 in the latest RFC's.
(Pekka Savola)
06/30/2001 Check for possible buffer overflows; replace strcpy with
strncpy. No fatals found. Remove redunant radvd -t check.
(Pekka Savola)
06/24/2001 Fix 1-byte overflow in /proc/net/igmp6 handling,
clean out possible memory garbage when sending RA's
(patch from <yoshfuji@linux-ipv6.org>).
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.

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

11/20/96 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)
