cfe34a316e Implements hostcache and recursive next hops. 
Hostcache is a structure for monitoring changes in a routing table that
is used for routes with dynamic/recursive next hops. This is needed for
proper iBGP next hop handling.

824de84d48 Do not start with huge OSPF FIBs. 
Most OSPF instances don't need 64k FIB fields. This change halves
resident memory usage on small OSPF networks.

0ea8fb4abe Fixes and enhancements in 'show ospf state' command. 
Now it shows a distance, option to change showing reachable/all network
nodes and better handling of AS-external LSAs in multiple areas. The
command 'show ospf topology' was changed to not show stubnets in both
OSPFv2 and OSPFv3 (previously it displayed stubnets in OSPFv2).

7969ea3b41 Fixes a bug in OSPF on NBMA interfaces. 
A very tricky bug. OSPF on NBMA interfaces probably never really worked.
When a packet was sent to multiple destinations, the checksum was
calculated multiple times from a packet with already filled checksum
field (from previous calculation). Therefore, many packets were sent
with an invalid checksum.

- Adds bgp_originator_id and bgp_cluster_list route attributes.
 - Adds dotted quad filter datatype (for router IDs, used by
   bgp_originator_id and ospf_router_id route attributes).
 - Fixes pair ~ pair set matching.

53434e44a9 Better flushing of interfaces. 
When device protocol goes down, interfaces should be flushed
asynchronously (in the same way like routes from protocols are flushed),
when protocol goes to DOWN/HUNGRY.

This fixes the problem with static routes staying in kernel routing
table after BIRD shutdown.

ff2857b03d Many changes in (mainly) kernel syncers. 
- BSD kernel syncer is now self-conscious and can learn alien routes
- important bugfix in BSD kernel syncer (crash after protocol restart)
- many minor changes and bugfixes in kernel syncers and neighbor cache
- direct protocol does not generate host and link local routes
- min_scope check is removed, all routes have SCOPE_UNIVERSE by default
- also fixes some remaining compiler warnings

dca75fd7c2 Removes phantom protocol from the pipe design. 
It seems that by adding one pipe-specific exception to route
announcement code and by adding one argument to rt_notify() callback i
could completely eliminate the need for the phantom protocol instance
and therefore make the code more straightforward. It will also fix some
minor bugs (like ignoring debug flag changes from the command line).

c83876265e Fixes a tricky bug in the pipe protocol. 
When uncofiguring the pipe and the peer table, the peer table was
unlocked when pipe protocol state changed to down/flushing and not to
down/hungry. This leads to the removal of the peer table before
the routes from the pipe were flushed.

The fix leads to adding some pipe-specific hacks to the nest,
but this seems inevitable.

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

6cb8f742f1 Better handling of well-known communities. 
Process well-known communities before the export filter (old behavior is
to process these attributes after, which does not allow to send route
with such community) and just for routes received from other BGP
protocols. Also fixes a bug in next_hop check.

ea89da381f Workaround for stupid callback scheduler. 
There is no reak callback scheduler and previous behavior causes
bad things during hard congestion (like BGP hold timeouts).

Smart callback scheduler is still missing, but main loop was
changed such that it first processes all tx callbacks (which
are fast enough) (but max 4* per socket) + rx callbacks for CLI,
and in the second phase it processes one rx callback per
socket up to four sockets (as rx callback can be slow when
there are too many protocols, because route redistribution
is done synchronously inside rx callback). If there is event
callback ready, second phase is skipped in 90% of iterations
(to speed up CLI during congestion).

Although standard says that if we receive AS_PATH_CONFED_*
(and we are not a part of a confederation) segment, we should
drop session, nobody does that and it is unwise to do that.

Now we drop session just in case that peer ASN is in
AS_PATH_CONFED_* segment (to detect peer that considers BIRD
as a part of its confederation).

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).

a97122a3ca 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
generate stub link in both cases (in the first case together with PTP
link).

And because of buggy detection of unnumbered networks, for numbered
networks the code creates stub links with 0.0.0.0/32.

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

Martin Mares
38a608c55a Rewritten the I/O loop. All socket operations are now safe, meaning that 
you can delete the socket from anywhere in the hooks and nothing should break.
Also, the receive/transmit buffers are now regular xmalloc()'ed buffers,
not separate resources which would need shuffling around between pools.

sk_close() is gone, use rfree() instead.

0077aab4f9 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
to missing routes or worse to bug()s like "Router parent does not have
next hop" or just segfaults. The patch fixes this but in the long term a
redesign is required here. Note that the patch doesn't worse the
situation, instead it prevents the problems stated. The redesign is
required to handle multiple routes to small subnets properly.

(by Andreas)

Feela, I think that this is at least a good temporary fix, but it's
of course up to you to decide.

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

(Andreas)
 2004-05-31 18:13:14 +00:00
Martin Mares
3cb96cd343 The initial sequence number for RIP md5 authentication was always zero. 
Bad as when bird e.g. was running for two weeks and then restarted it
would take another two weeks until the peers of this router would accept
data again from this router, as the sequence number would be too low.
Changed to use the the current system time as the starting sequence
number which is a more sane start value.

4a02013767 Make RIP nolisten mode actually work. The socket is required for 
sending, the received data has to be discarded instead.

11d4474c17 Better selection of link-local NLRI addresses, at least for our own 
address. Need to do it better for the other neighbors -- the current
solution works only if they use the standard 64+64 global addresses
and the interface identifier in lower 64 bits is the same as for the
link-scope addresses.

it's pretty normal: during feeding of the protocol, a new route can appear
which will be announced normally and then repeated by the feeding process.

28323d9ddb Several minor RIP changes (Pavel, please check as usually): 
o  Use FIB_ITERATE_INIT instead of calling the function fit_init()
      which is explictly marked as private in route.h.
   o  When printing trace messages, don't spit out protocol name twice.
   o  Some messages are a bit more verbose.
   o  Added a bunch of FIXME's.
   o  When running in broadcast mode, don't forget to bind the local
      end of the socket to the same broadcast address, so that we don't
      get the broadcasts looped back via different interface. I'm just
      going to look up the same problem for multicasts.

ce1da96ee7 Added commands show route protocol <p>' and show route import <p>' which 
show the routing table as exported to the protocol given resp. as returned
from its import control hook.

To get handling of filtered extended attributes right (even in the old
`show route where <filter>' command), the get_route_info hook gets an
attribute list and all protocol specific rte attributes are contained
there as temporary ones. Updated RIP to do that.

Added ea_append() which joins two ea_list's.
