Rather than reloading kernel routes immediately when an RTM_DESYNC is seen,
set (or extend) a timer and only reload when this expires. Avoids repeatedly
dumping full kernel routes (thus generating more load) when the machine has
problems keeping up with messages on the route socket. (if you see lots of
repeated "reloading interface list and routing table" in ospfd logs, this
will help).

First bits to support opaque LSA. Type-9, 10 and 11 are LSA that can
hold about any data you like and is used for things like greaceful
reload. Implement the basic redistribute logic and LSDB handling but
the data sent is currently not looked at.

Rewrite the lsack generation. Make it more like the lsupdate code.

Use offsetof() instead of writing our own version (...which generates
warnings from gcc4)

implement support for fast hello packets.

if route-dead-time is set to "minimal" (rather than a number of
seconds), the dead time is set to 1 second and hellos are sent at
the interval specified by fast-hello-interval in msecs. this is non
standard wrt to the ospf rfc, but it does interoperate with at least
one other router vendor.

this allows much better responsiveness to l3 topology changes than
the standard intervals allow. if i yank a cable to one of my
upstreams, the routes adjust in a second rather than the default
of 40 i was running with before. the users dont even notice something
changed.

allow spf-delay and spf-holdtime to be specified in msec so ospfd can
better respond to rapid topology changes.

Make it possible to set the metric and LSA type for redistributed routes.
Mostly based on a diff by Pierre-Yves Ritschard (I just simplified the parser
code). OK norby@

It seems that 60 secs is a reasonable amount of time to reach state FULL.

Prevent the neighbor FSM from getting stuck forever in state EXSTART.

Increase ADJ_TMOUT to prevent loss of adjacency during bulk ls update
transfers.

Do no longer force the default router priority to 0.
Ospfd can be used as DR or BDR since quite some time so there is no need to
make ospfd ineligible as DR or BDR.

Add check for key lengths. Based on diff from Jason Ackley.
Reworked by me.

Add support for crypt authentication (MD5).

The LSA seq_num should be unsigned as it is expected by ntohl/htonl() even
though the seq_num needs to be compared as signed number.
No idea how IETF came up with such a stupid idea especially because the
seq_num is not allowed to wrap.

Welcome ospfd
started by Esben Norby some time ago by using the imsg/three process framework
of bgpd. He implemented the basic concept plus the ospf finite state machines.
Later I joined and helped him cleanup, debug and extend his work.
Right now it is not particularly useful, major parts are still missing but is
imported to allow more people to work on it.
status:
The basic protocol works for broadcast networks and the LS database is
synchronized and updated. It is not possible to be DR or BDR on a network
and other interface types like point-to-point are not yet supported.
The shortest path tree is not calculated and so no routing information is
exchanged with the kernel FIB.

Not yet connected to the builds.
