Removed BITS_PER_IP_ADDRESS, MAX_PREFIX_LENGTH, BIRD_AF

Explicit setting of AF_INET(6|) in IP socket creation. BFD set to listen
on v6, without setting the V6ONLY flag to catch both v4 and v6 traffic.

Initial commit on integrated BIRD

New data types net_addr and variants (in lib/net.h) describing
network addresses (prefix/pxlen). Modifications of FIB structures
to handle these data types and changing everything to use these
data types instead of prefix/pxlen pairs where possible....

145368f5 04/23/2014 11:54 AM Ondrej Zajicek

Extends multipath support for OSPF.

Fixes cases where the same network or external route are propagated by
several OSPF routes and some other corner cases in next hop construction
and ECMP. Allows to specify whether external routes should be merged.

Thanks to Peter Christensen for the original patch.

48e5f32d 02/06/2014 04:46 PM Ondrej Zajicek

Many changes in I/O and OSPF sockets and packet handling.

I/O:
- BSD: specify src addr on IP sockets by IP_HDRINCL
- BSD: specify src addr on UDP sockets by IP_SENDSRCADDR
- Linux: specify src addr on IP/UDP sockets by IP_PKTINFO
- IPv6: specify src addr on IP/UDP sockets by IPV6_PKTINFO...

1ec52253 11/19/2013 09:33 PM Ondrej Zajicek

BFD protocol, ready for release.

Supports OSPF and BGP and also statically configured sessions.

70e212f9 06/25/2013 01:39 PM Ondrej Zajicek

TTL 255 for traffic to direct neighbors.

Thanks to Simon Dickhoven for the original patch for RIPng.

ef4a50be 06/24/2013 02:37 PM Ondrej Zajicek

Better packet priority and traffic class handling.

8df02847 04/17/2013 11:06 AM Ondrej Zajicek

Fixes a compatibility issue in OSPFv2 PtP links.

BIRD used zero netmask in hello packets on all PtP links, not just on
unnumbered ones. This patch fixes it and adds option 'ptp netmask'
for overriding the default behavior.

Thanks to Alexander V. Chernikov for the original patch.

dd4da6f6 10/31/2012 04:14 PM Ondrej Zajicek

OSPF NSSA support, part one.

ab164971 03/28/2011 11:41 PM Ondrej Zajicek

Fixes a nasty bug in OSPF.

Sending malformed network prefixes in LSAs causes OSPF to crash
just after the LSA is propagated to the other routers.

8e48831a 03/17/2011 02:53 PM Ondrej Zajicek

Vastly improved OSPF reconfiguration.

Now it can handle a change in iface pattern structure.

Temporary OSPF commit - socket changes.

c27b2449 02/08/2010 03:01 PM Ondrej Zajicek

Shows source (Router ID) for OSPF routes and adds such attribute.

A sad thing is that we does not have a 'router_id' filter type,
so it must be given as decimal number in filters.

29bfbae7 01/07/2010 03:24 PM Ondrej Zajicek

Debugging change leaked to repository.

f7574707 12/14/2009 08:17 PM Ondrej Zajicek

Temporary OSPFv3 development commit

b082c1bf 07/05/2009 06:26 PM Ondrej Zajicek

Fixes OSPF on big-endians.

Hmm, #ifdef is not very typo-safe.

38675202 06/11/2009 03:25 PM Ondrej Zajicek

Implements an option that allows to change a set of stub networks.

3d15dcdb 06/10/2009 09:45 PM Ondrej Zajicek

Changes OSPF to generate stub networks for non-primary addresses.

Also does some reorganization in RT LSA announcement.

024c310b 04/08/2009 06:15 PM Ondrej Zajicek

Fixes broken cryptographic authentication in OSPF

Cryptographic authentication in OSPF is defective by
design - there might be several packets independently
sent to the network (for example HELLO, LSUPD and LSACK)
where they might be reordered and that causes crypt....

8298d780 04/06/2009 02:17 PM Ondrej Zajicek

Better OSPF packet tracing log messages.

Replaces old OSPF packet tracing messages with
uniform messages with packet dumps.

94c42054 03/15/2005 10:06 PM Ondrej Filip

Added new parametr 'rx buffer <num>'. BIRD is able to receive
very large packets (if configured).

e6ea2e37 03/15/2005 08:51 PM Ondrej Filip

Maximal packet size in virtual links is 576.

e300066d 03/14/2005 11:24 AM Ondrej Filip

OSPF can accept larger packets than MTU.

d8c7d9e8 02/20/2005 04:27 AM Ondrej Filip

Since now I can also use 'dead interval', not just 'dead counter'.

60e04f04 02/18/2005 06:51 PM Ondrej Filip

Minor bugfix: Summary LSA for aggregated area was always propagated with
metric = 1. Now it's metric of most distant component.

9912fa51 02/12/2005 10:18 PM Ondrej Filip

Bugfix - cost of interface can be larger than 0xffff

8d94a524 07/16/2004 08:27 AM Ondrej Filip

Added handling of STUB bool.

86c84d76 07/15/2004 04:37 PM Ondrej Filip

Huge OSPF database redesign. Since now, all LSAs of all areas
are in single database. This avoids duplication of external LSAs and
fixes bug in external LSA distribution.

3b16080c 07/14/2004 09:46 PM Ondrej Filip

Multiple OSPF areas can be attached.
Origination of summary LSA works.
Routing table calculation works.
Virtual links works.

Well, I hope, OSPF is fully compatible with RFC2328!!!!

62eee823 07/13/2004 09:27 PM Ondrej Filip

Default tick = 1. The today's CPU is fast enough.

621ccdfe 07/13/2004 11:58 AM Ondrej Filip

Bugfix - options bits were not included in LSAs
Bugfix - E bit was not unset on stub areas.

3e2bd0f1 06/26/2004 08:15 PM Ondrej Filip

Md5 authentification added (unsested).
Packet receiving clean up.

98ac6176 06/25/2004 04:39 PM Ondrej Filip

A lot of changes:
- metric is 3 byte long now
- summary lsa originating
- more OSPF areas possible
- virtual links
- better E1/E2 routes handling
- some bug fixes..

I have to do:
- md5 auth (last mandatory item from rfc2328)
- !!!!DEBUG!!!!! (mainly virtual link system has probably a lot of bugs)...

1a61882d 06/11/2004 09:36 AM Ondrej Filip

Better routing table calculation. We are ready to work with
multiple OSPF areas.

7df86c25 06/09/2004 12:39 PM Ondrej Filip

Better checking of configuration.

b8f17cf1 06/06/2004 04:00 PM Ondrej Filip

d631698e 06/06/2004 02:27 PM Ondrej Filip

Indentation.

2e10a170 06/06/2004 09:37 AM Ondrej Filip

Indentation.

66261211 06/06/2004 09:13 AM Ondrej Filip

Struct area_net changed.

b9ed99f7 06/06/2004 08:55 AM Ondrej Filip

Cleanup in iface.c

c76ba51a 06/04/2004 04:30 PM Ondrej Filip

lsack.c cleaned. Better names for functions and
DIRECT acks can be sent in one packet now.

39e517d4 06/04/2004 12:53 PM Ondrej Filip

hello.c and hello.h cleaned up. No design changes.

035f6acb 06/01/2004 01:12 PM Ondrej Filip

Patch from Andreas Steinmetz <>

d83faf8d 05/31/2004 08:53 PM Martin Mares

static declarations don't belong to includes. (And most of them were
redundant anyway.)

4ef3dccf 05/31/2004 06:13 PM Martin Mares

The OSPF authentication type was sent in host byte order instead of of
network byte order thus breaking interoperability with other routing
daemons on litte endian machines. The patch fixes this but note that
this breaks compatability with older bird installations using OSPF and...

c11007bc 08/26/2003 10:41 AM Ondrej Filip

Endian-related bug fixes sent by Krzysztof Szuster <>

c926eee7 08/12/2001 12:04 AM Ondrej Filip

Area networks added into configuration.

78e2c6cc 08/11/2001 02:01 PM Ondrej Filip

I will not originate the same lsa before MINLSINTERVAL.

b02e4011 09/04/2000 07:42 PM Ondrej Filip

I allocate struct ifa before unlocking. So route exported to OSPF are correct.
I work also with interfaces that have some problems with socket opening.
I declare them as stub.

fdb19982 09/03/2000 10:18 PM Ondrej Filip

Serious bug in ext lsa origination found. Going for 1.0.4.

e3bc10fd 09/02/2000 08:54 AM Ondrej Filip

Added stub interface. (Interface which is propagated to OSPF but
it does not sends nor listens packets.)

I added some new options, please look at it and look into doc if it's OK.

a190e720 09/02/2000 12:03 AM Ondrej Filip

Added hellos on NBMA networks. (I don't violate RFC now.)

423230f2 06/08/2000 01:49 AM Ondrej Filip

Ehm, my (B)DR election was based on router id, but RFC says ip!
