b082c1bfcc Fixes OSPF on big-endians.
Hmm, #ifdef is not very typo-safe.

3d15dcdb1c Changes OSPF to generate stub networks for non-primary addresses.
Also does some reorganization in RT LSA announcement.

024c310b53 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.
sequence number error.

That can be workarounded by not incresing sequence number
too often. Now we update it only when last packet was sent
before at least one second. This can constitute a risk of
replay attacks, but RFC supposes something similar (like time
in seconds used as CSN).

8298d780be Better OSPF packet tracing log messages.
Replaces old OSPF packet tracing messages with
uniform messages with packet dumps.

94c42054ea Added new parametr 'rx buffer <num>'. BIRD is able to receive
very large packets (if configured).

60e04f0413 Minor bugfix: Summary LSA for aggregated area was always propagated with
metric = 1. Now it's metric of most distant component.

9912fa51c8 Bugfix - cost of interface can be larger than 0xffff 2005-02-12 22:18:48 +00:00

86c84d76b7 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.

3b16080c97 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!!!!

621ccdfe5a Bugfix - options bits were not included in LSAs
Bugfix - E bit was not unset on stub areas.

98ac61766d 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)
	- 2328 appendig E

d83faf8dc4 static declarations don't belong to includes. (And most of them were
redundant anyway.)

4ef3dccfa1 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
password authentication

b02e40111e 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.

e3bc10fdc4 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.
