9d8856897f Protocol engine bug fixes:
o  Make proto_config->table always point to the right
      table even if it should be the default one.
   o  When shutting down, kill protocol in reverse order
      of their priority.
   o  When stopping a protocol down, disconnect it from
      routing tables immediately instead of waiting
      for the delayed protocol flush event.

Also added a protocol instance counter (used by KRT code
in very magic ways).

0e02abfd57 From now we support multiple tables. The master_table variable is
definitely gone. Both rte_update() and rte_discard() have an additional
argument telling which table should they modify.

Also, rte_update() no longer walks the whole protocol list -- each table
has a list of all protocols connected to this table and having the
rt_notify hook set. Each protocol can also freely decide (by calling
proto_add_announce_hook) to connect to any other table, but it will
be probably used only by the table-to-table protocol.

The default debugging dumps now include all routing tables and also
all their connections.

5056c559c4 Changed syntax of attaching filters to protocols to hopefully the final
version:

	EXPORT <filter-spec>	for outbound routes (i.e., those announced
				by BIRD to the rest of the world).
	IMPORT <filter-spec>	for inbound routes (i.e., those imported
				by BIRD from the rest of the world).

where <filter-spec> is one of:

	ALL			pass all routes
	NONE			drop all routes
	FILTER <name>		use named filter
	FILTER { <filter> }	use explicitly defined filter

For all protocols, the default is IMPORT ALL, EXPORT NONE. This includes
the kernel protocol, so that you need to add EXPORT ALL to get the previous
configuration of kernel syncer (as usually, see doc/bird.conf.example for
a bird.conf example :)).

7dc4827c96 Added everything protocols need to know about multiple routing tables,
i.e. struct proto now contains field 'table' pointing to routing table
the protocol is attached to. Use this instead of &master_table.

Modified all protocols except the kernel syncer to use this field.

529c414953 Allow input and output filters (only accept/reject style as we didn't define
modifying filters yet) to be attached to protocol instances.

c1f8dc9149 Yes, joining the crew. Sorry for being late. Added dummy functions for OSPF. 1999-03-09 22:27:43 +00:00

0e889c5254 Added a hack forcing protocols with priority>0 to be started up
immediately. Grrr, need to find a real solution some day.

b2280748ad Introduced protocol priority (all 'normal' protocols should use the
default zero priority). No more "kernel syncer initialized before
device routes" problems.

f4aabcee62 Perform gracious shutdown upon receipt of SIGTERM. Finally we can
test the whole protocol shutdown code... :)

1a54b1c6ac Implemented real cleanup and pruning of routing table on protocol shutdown. 1999-02-13 19:15:28 +00:00

67bd949a52 Real implementation of protocol state machines. Delayed startup/shutdown
should work now. Initial feeding of protocols by interfaces/routes is
done from the event queue to prevent unwanted recursion.

31b3e1bbf5 Implemented new configuration/reconfiguration interface and defined protocol
state machines. Full explanation will follow soon.

0432c0173b Split protocol init to building of protocol list and real protocol init.
Added kernel route table syncer skeleton.

47b793064c Solve chicken-and-egg problems with protocol startup. We now queue all inactive
protocols and don't send route/interface updates to them and when they come up,
we resend the whole route/interface tables privately.

Removed the "scan interface list after protocol start" work-around.
