Ondrej Zajicek 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.

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

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).

(ECONNABORTED).

Ondrej Zajicek 44f26560ec Workaround for some broken BGP implementations that skip initial KEEPALIVE. 2010-02-02 10:14:21 +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 52b9b2a178 Rename as_path_get_last/as_path_get_first to be consistent. 2009-10-12 20:44:58 +02:00
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).
