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.

9449c91ab2 Added `show route for <prefix-or-ipa>' which looks up route leading to 
given network.

08f0290a1e Changed semantics of the rt_update hook. The attribute list we pass now 
contains all attributes, not just the temporary ones. This avoids having
to merge the lists inside protocols or doing searches on both of them.

Also, do filtering of routes properly. (I'd like to avoid it, but it's
needed at least in the krt protocol.)

0521e4f684 rt_prune: Don't kill routes from protocols in FS_FEEDING state. If debugging, 
call fib_check() on the table's fib.

33a368ad59 Implemented show route count' which is show route stats' with 
exception that it doesn't print the routes themselves.

0d3070824d Don't count networks with no routes (they are not displayed at all and 
will be removed during the next garbage collection pass).

23693958aa Implemented `show route <...> stats'. 2000-05-07 11:28:59 +00:00
Martin Mares
ce1da96ee7 Added commands show route protocol <p>' and show route import <p>' which 
show the routing table as exported to the protocol given resp. as returned
from its import control hook.

To get handling of filtered extended attributes right (even in the old
`show route where <filter>' command), the get_route_info hook gets an
attribute list and all protocol specific rte attributes are contained
there as temporary ones. Updated RIP to do that.

Added ea_append() which joins two ea_list's.

67be5b23cd When rte_update is called for an identical route, don't announce anything. 
Please implement the rte_same hook in your protocols. It should just
compare your metrics stored directly in rte, the rest is done by the core.

93a786cb03 Removed a lot of unused variables. 
Please try compiling your code with --enable-warnings to see them. (The
unused parameter warnings are usually bogus, the unused variable ones
are very useful, but gcc is unable to control them separately.)

8f6accb5bb Event handlers no longer return re-queue flag. Instead of using it, just 
call ev_schedule() on the same handler which should work perfectly now.

3991d84e8f Changed initialization of protocol list -- now we call proto_build() instead 
of calling the protocols manually.

Implemented printing of dynamic attributes in `show route all'.

Each protocol can now register its own attribute class (protocol->attr_class,
set to EAP_xxx) and also a callback for naming and formatting of attributes.
The callback can return one of the following results:

	GA_UNKNOWN	Attribute not recognized.
	GA_NAME		Attribute name recognized and put to the buffer,
			generic code should format the value.
	GA_FULL		Both attribute name and value put to the buffer.

Please update protocols generating dynamic attributes to provide
the attr_class and formatting hook.

221135d6bf Include "lib/string.h" instead of <string.h>. It should give us bzero() 
and other non-portable functions on all systems.

6b9fa32080 Great cleanup of debug messages. LOCAL_DEBUG turned off in most modules, 
several debug() calls converted to DBG().

cfd46ee4c5 Added debugging of communication between protocols and routing tables. 
Just ask for "debug routes" if you want to see the routes and "debug filters"
if you want even the rejected ones.

b9626ec6ea Garbage collector events and counters are now per table and one day 
they can be made configurable if it turns out to be useful.

4c1b4e1a58 If the user has specified identical preferences for instances of different 
protocols, break the tie by comparing addresses, so we keep the ordering
unambiguous.

bf8558bc9c Converted shutdown to a kind of reconfiguration, it's no more handled 
as a exception in protocol state machines. Introduced a `shutdown'
CLI command. Killed few reconfiguration bugs.

50fe90edf3 First attempt on dynamic reconfiguration. There are still lots of bugs 
and problems to solve, but the hardest part works.

0da472d7e8 Except for special protocols (nowadays only the kernel syncer), don't 
export host and link scope routes.

0d70292d88 Events now return a value. If it's non-zero, the event is re-queued 
for processing in next event cycle. This can be used to prevent background
actions (hint: user commands) from hogging the CPU for too long time.

8c943173ce Allow announces of rte's to protocols in FS_FEEDING state. 
Else, we would get chicken-egg problems in the table-to-table protocol.

7de45ba4a0 Kernel route syncer supports multiple tables. 
The changes are just too extensive for lazy me to list them
there, but see the comment at the top of sysdep/unix/krt.c.
The code got a bit more ifdeffy than I'd like, though.

Also fixed a bunch of FIXME's and added a couple of others. :)

bb027be1e2 Added extra argument to rt_update hook which contains a pointer to the 
temporary attribute list.
 1999-05-31 18:55:35 +00:00
Martin Mares
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.
