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).

b722fe7ebd Fixes bug in OSPF packet retransmission. 
If a DBDES packet from a master to a slave is lost, then the old code
does not retransmit it and instead send a next one with the same
sequence number. That leads to silent desynchronization of LSA
databases.

8298d780be Better OSPF packet tracing log messages.

48d79d521c Better handling of AS4 optional attribute errors 
AS4 optional attribute errors were handled by session
drop (according to BGP RFC). This patch implements
error handling according to new BGP AS4 draft (*)
 - ignoring invalid AS4 optional attributes.

82a79586e5 Better handling of too long attributes 
This patch extends the length for attributes from 1024 to 2048
(because both AS_PATH and AS4_PATH attributes take 2+4 B per AS).

If there is not enough space for attributes, Bird skips that
route group. Old behavior (skipping remaining attributes)
leads to skipping required attributes and session drop.

a9dc5e1ef2 Fixes another bug in packet retransmissions. 
When slave was in full state, it didn't retransmit
lost packets. That leads to OSPF connection locked
in states loading-full.

0844b65d13 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.

It also contains related fix from Yury Shevchuk that
properly resets DB summary list iterator.

without capabilities. Also cease error subcodes descriptions
(according to [RFC4486]) are added.

591211557f Fixes bug related to reconfiguration of BGP. 
BGP keeps its copy of configuration ptr and didn't update it during
reconfiguration. But old configuration is freed during reconfiguration.
That leads to unnecessary reset of BGP connection during reconfiguration
(old conf is corrupted and therefore different) and possibly other strange
behavior.

b21f68b4cd Fix bugs in OSPF MD5 authentication. First bug is that default 
values for MD5 password ID changed during reconfigure, Second
bug is that BIRD chooses password in first-fit manner, but RFC
says that it should use the one with the latest generate-from.

It also modifies the syntax for multiple passwords.
Now it is possible to just add more 'password' statements
to the interface section and it is not needed to use
'passwords' section. Old syntax can be used too.

e16466b379 Fix race condition that breaks BGP connections after reconfigure. 
RFC says that only connections in OpenConfirm and Established state
should participate in connection collision detection.

The current implementation leads to race condition when both sides
are trying to connect at the almost same time, then both sides
receive OPEN message by different connections at the almost same
time and close the other connection. Both connections are
closed and the both sides end in  start/idle or start/active
state.

a3b70dc499 Two new informative CLI commands for OSPF. 
Two new CLI commands for OSPF giving nice informative (and still machine
parsable) representation of OSPF network graph (based on datas from the
LSA database).

The first command (show ospf topology) shows routers, networks and stub
networks, The second command (show ospf state) shows also external
routes and area-external networks and routers propagated by given area
boundary router.

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.

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.
