b7c4898106 Compilation was failing without OSPF or RIP protocol - FIXED. 2011-05-05 14:14:20 +02:00
Ondrej Zajicek
ab16497189 Fixes a nasty bug in OSPF. 
Sending malformed network prefixes in LSAs causes OSPF to crash
just after the LSA is propagated to the other routers.

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.

c429d4a4ba Restrict export of device routes to the kernel protocol. 
In usual configuration, such export is already restricted
with the aid of the direct protocol but there are some
races that can circumvent it. This makes it harder to
break kernel device routes. Also adds an option to
disable this restriction.

4d9a0d1f02 Update lastmod in 'ignored' case only for RIP routes. 2010-03-24 10:42:25 +01:00

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).

9db74169be Fixes protocol statistics for pipes. 2010-02-13 10:44:46 +01:00

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.

11361a1015 Implements route re-feed. 
This can be used to re-feed routes to protocol after soft change in
export filters.

11787b8473 Fixes some problems in pipes. 
For transparent pipes, loop detection works correctly now.
Pipes are now more symmetric - in both directions filtering
is done in do_rte_announce().

069bfcb53c Fixes serious bug in core related to route filtering. 
If protocol announces a route, route is accepted by import filter to
routing table, and later it announces replacement of that route that is
rejected by import filter, old route remains in routing table.

024e633c16 Fixes bug that caused losing of some routes. 
When update changes preferred route in such a way that
it ceased to be preferred, the new route was linked
to wrong place and lost.

40b65f947a Fixes bug in pipe route filtering. 
Routes comming through pipe from primary to secondary table were
filtered by both EXPORT and IMPORT filters, but they should be
only filtered by EXPORT filters.

13b75bacf7 protocol->import_control() could potentially call rte_cow() as well. 
AFAIK it doesn't happen in any of our protocol, but better be sure.
 2003-08-13 20:04:39 +00:00
Martin Mares
2adab6ae9c This was a potential memory leak, but not the one Feela observed. 
This one could happen when an import filter of some protocol modified
the rte (so that it would be rte_cow()ed) and later rejected it.
