Ondrej Zajicek e3c460bc90 Fixes some past config grammar update that caused password related regression. 2009-01-16 12:08:07 +01:00
Ondrej Zajicek 3b108f18e8 One null-pointer dereference bugfix hidden in whitespace changes 2009-01-16 10:58:52 +01:00
Ondrej Zajicek 0dd7ccc766 Fix typo. 2009-01-13 19:25:27 +01:00
Ondrej Zajicek 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.

Ondrej Zajicek f20907adf6 Fixes bug in OSPF 
Checksum was not recalculated when LSA was changed and
packets with bad checksum were sent.
 2009-01-11 10:47:41 +01:00
Ondrej Zajicek 165a622727 Adds support for fallback to capabilityless BGP connect 
When capability related error is received, next connect will be
without capabilities. Also cease error subcodes descriptions
(according to [RFC4486]) are added.
 2008-12-24 17:24:41 +01:00
Ondrej Zajicek 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.
 2008-12-24 12:18:10 +01:00
Ondrej Zajicek 11b32d9117 Major changes to BGP 
Fixes two race conditions causing crash of Bird, several unhandled
cases during BGP initialization, and some other bugs. Also changes
handling of startup delay to be more useful and implement
reporting of last error in 'show protocols' command.
 2008-12-19 01:34:39 +01:00
Ondrej Zajicek 3f670371cf OSPF routes appeared with random value of ospf_tag attribute. 
This patch fixes it.
 2008-11-14 21:13:56 +01:00
Ondrej Zajicek aebe06b40c Proper format functions for ORIGINATOR_ID, CLUSTER_LIST 2008-11-08 23:33:22 +01:00
Ondrej Zajicek 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.
 2008-11-08 17:24:23 +01:00
Ondrej Zajicek fd91ae3325 Fix problem with local time changes. 2008-11-05 22:36:49 +01:00
Ondrej Zajicek 1389f3699f Fixes bugs in IPv6 code caused by recent commits. 2008-11-05 21:39:04 +01:00
Ondrej Zajicek a39b165e45 Multihop BGP was completely broken, because listening socket has always 
ttl 1.
 2008-11-01 16:58:40 +01:00
Ondrej Zajicek a92fe60717 Implementation of route server. 2008-11-01 12:55:43 +01:00
Ondrej Zajicek 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.

Ondrej Zajicek f0ad56f441 Fixes some sloppiness of commit a3b70dc499. 2008-10-28 16:10:42 +01:00
Ondrej Zajicek a98fbf0f12 Merge branch 'dev' into out 2008-10-27 00:20:22 +01:00
Ondrej Zajicek 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.

Ondrej Zajicek 52586ccdf1 Missing newline. 2008-10-26 23:53:05 +01:00
Ondrej Zajicek 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.
 2008-10-26 23:43:13 +01:00
Ondrej Zajicek b6bf284a90 Bugfixes in MULIT_EXIT_DISC attribute handling. 
- Old MED handling was completely different from behavior
   specified in RFCs - for example they havn't been propagated
   to neighboring areas.

 - Update tie-breaking according to RFC 4271.

 - Change default value for 'default bgp_med' configuration
   option according to RFC 4271.

	- 2328 appendig E

Ondrej Filip 9b13345889 Hotfix for router's parent without nexthop.

Ondrej Filip 035f6acbfe Patch from Andreas Steinmetz <ast@domdv.de> 2004-06-01 13:12:10 +00:00
Ondrej Filip 7fdd338c36 ALIGN -> BIRD_ALIGN 2004-06-01 10:28:25 +00:00
Martin Mares bb68ad2fd3 Documented the pxlen parameter. 2004-05-31 22:22:21 +00:00
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.
 2004-05-31 21:48:19 +00:00
Martin Mares 6a57bb3110 Killed a couple of unused variables. 
We really should compile with warnings enabled.
 2004-05-31 20:57:38 +00:00
Martin Mares d83faf8dc4 static declarations don't belong to includes. (And most of them were 
redundant anyway.)
 2004-05-31 20:53:22 +00:00
Martin Mares 0757bcb728 One space more. 2004-05-31 20:35:19 +00:00
Martin Mares 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.
 2004-05-31 18:16:42 +00:00
Martin Mares 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.

(by Andreas, cleaned up by me)
 2004-05-31 18:11:16 +00:00
Martin Mares 4a02013767 Make RIP nolisten mode actually work. The socket is required for 
sending, the received data has to be discarded instead.

Martin Mares 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.
