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...

with some broken implementations.

Fix OSPF protocol error recovery behavior.

When OSPF neighbor state drops down to EXSTART,
clear LSA request and retransmit lists, as specified
by RFC. I hope that this will prevent oscillations
between EXSTART and LOADING states, which sometimes
happened....

23d67029 01/11/2009 11:14 AM Ondrej Zajicek

packets with bad checksum were sent.

a97122a3 10/26/2008 10:43 PM Ondrej Zajicek

Bugfix in LSA origination for PTP OSPF links.

The code generating LSAs for PTP OSPF links is buggy. The old behavior
is that it generates PTP link if there is a full/ptp neighbor and stub
link if there isn't. According to RFC 2328, the correct behavior is to...

226cb2bc 08/25/2008 12:51 PM Ondrej Filip

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!!!!

490767ad 07/13/2004 10:10 PM Ondrej Filip

Add more reasonable options to LSAs. (But it seems, that it's ignored.)

Bugfix - E bit was not unset on stub areas.

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

A lot of changes:
- metric is 3 byte long now

I have to do:
- md5 auth (last mandatory item from rfc2328)

Documented the pxlen parameter.

0077aab4 05/31/2004 06:16 PM Martin Mares

The code was broken for external /29 to /32 routes. Assuming that you
have one machine publishing a route to 10.1.1.3/32 and another one
publishing a route to 10.1.1.4/32. If the first machine went down the
route to 10.1.1.4/32 was wrongly killed by the old code, leading either...
