Ondrej Zajicek 4e5fb4b60c Skip LSA host<->network endianity conversions on big endians. 2010-04-25 20:12:34 +02:00
Ondrej Zajicek 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).

Ondrej Zajicek 3b89a2327b Fixes several problems in OSPF vlink implementation. 2010-04-21 21:50:38 +02:00
Ondrej Zajicek 6e80676096 Fixes next hop calculation on NBMA and parallel PTP links. 2010-04-11 12:22:47 +02:00
Ondrej Zajicek 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.
 - Documentation updates.

Ondrej Zajicek e7b76b9760 Temoporary OSPF commit - socket changes. 2010-03-11 18:07:24 +01:00
Ondrej Zajicek 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.
 2010-02-27 16:00:07 +01:00
Ondrej Zajicek 3075824dbd Comparing cluster list length should be later in bgp_rte_better(). 2010-02-26 14:09:24 +01:00
Ondrej Zajicek 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
 2010-02-26 10:55:58 +01:00
Ondrej Zajicek e81b440f68 Fix configure to enable warnings and fix most of them. 2010-02-21 14:34:53 +01:00
Ondrej Filip 89534cdae5 'rr client id' is not expression but ID (like router id). 2010-02-20 21:14:02 +01:00
Ondrej Zajicek 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).
 2010-02-13 12:26:26 +01:00
Ondrej Zajicek 9db74169be Fixes protocol statistics for pipes. 2010-02-13 10:44:46 +01:00
Ondrej Zajicek 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.
 2010-02-11 22:27:06 +01:00
Ondrej Zajicek a2ea1bac60 Moves errno.h include. 2010-02-11 21:19:20 +01:00

(ECONNABORTED).

Ondrej Zajicek 353729f513 Temporary OSPF commit - socket changes. 2010-02-11 10:23:35 +01:00
Ondrej Zajicek c27b2449d1 Shows source (Router ID) for OSPF routes and adds such attribute. 
A sad thing is that we does not have a 'router_id' filter type,
so it must be given as decimal number in filters.
 2010-02-08 16:01:03 +01:00
Ondrej Zajicek aa80826e4a Unnumbered OSPF interfaces should be always in the point-to-point mode. 2010-02-07 09:49:34 +01:00

Ondrej Zajicek 41677025ee Changes 'ignore communities' to 'interpret communities'. 2010-01-28 15:59:18 +01:00
Ondrej Zajicek 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.

Ondrej Zajicek 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).

Ondrej Zajicek 29c430f856 Changes handling of AS_PATH_CONFED_* segments in AS_PATH. 
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).

Ondrej Zajicek 20e94fb85b A change in OSPF and RIP interface patterns. 
Allows to add more interface patterns to one common 'options'
section like:

interface "eth3", "eth4" { options common to eth3 and eth4 };

Also removes undocumented and unnecessary ability to specify
more interface patterns with different 'options' sections:

interface "eth3" { options ... }, "eth4" { options ... };

Ondrej Zajicek 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).

Ondrej Zajicek 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.

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

Ondrej Zajicek 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.

Ondrej Zajicek e8ba557c7f Update capability handshake options 
Add 'capabilities' option, change default behavior to advertise ipv4,
add some checks and ignore incoming capabilities when capabilities
are disabled.

Ondrej Zajicek 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.

Ondrej Zajicek 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.

Ondrej Zajicek d901db3fb7 Fixes bug in packet retransmissions. 
When packet was lost during dbdes exchange, slave did not retransmit
it. That leads to OSPF connection locked in states exchange-exstart.

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.
