Age	Commit message (Collapse)	Author
1999-02-13	Implemented real cleanup and pruning of routing table on protocol shutdown.	Martin Mares

1999-02-13	Fixed bug in FIB_ITERATE_END: it assumed the control variable is named	Martin Mares
	"z". I've added an argument specifying name of the variable. Renamed "again" label in FIB_ITERATE_* to "fis_again" to avoid name clashes.
1999-02-13	config->router_id works again.	Martin Mares

1999-02-11	Real implementation of protocol state machines. Delayed startup/shutdown	Martin Mares
	should work now. Initial feeding of protocols by interfaces/routes is done from the event queue to prevent unwanted recursion.
1999-02-11	struct proto again contains instance name (a copy of proto->cf->name).	Martin Mares

1999-02-05	Implemented new configuration/reconfiguration interface and defined protocol	Martin Mares
	state machines. Full explanation will follow soon.
1999-01-12	Keep protocol data out of iface_patt.	Pavel Machek

1999-01-10	Initialize only protocols which are compiled in :)	Martin Mares

1999-01-10	New makefiles. Includes support for out-of-source-tree builds.	Martin Mares

1998-12-22	Oops, previous modification for passing NULL to fib_init() did not	Pavel Machek
	compile :-(.
1998-12-22	Allow NULL to init_fib().	Pavel Machek

1998-12-20	die() -> bug() where appropriate.	Martin Mares

1998-12-20	When printing a routing table, fib_check() it.	Martin Mares

1998-12-20	Rewrote fib functions to make them insert/delete/asynchronous-walk safe.	Martin Mares
	This is implemented in a way similar to lib/slists.h, but it took some more effort to make rehashing not disturb the readers. We do it by just taking _highest_ k bits of ipa_hash as our hash value and sorting each box by whole ipa_hash(). Consult FIB_ITERATE_* macros in nest/route.h. Implemented fib_check() debugging function and also rewrote the rehashing algorithm to use better thresholds and not to waste time by rehashing forth and back.
1998-12-08	Added source RTS_DUMMY for temporary routes. They should never appear	Martin Mares
	in the main table.
1998-12-07	Minor rte/rta interface changes:	Martin Mares
	o rte can now contain a pointer to both cached and uncached rta. Protocols which don't need their own attribute caching can now just fill-in a rta, link it to rte without any calls to attribute cache and call rte_update() which will replace rte->attrs by a cached copy. o In order to support this, one of previously pad bytes in struct rta now holds new attribute flags (RTAF_CACHED). If you call rte_update() with uncached rta, you _must_ clear these flags. In other cases rta_lookup() sets it appropriately. o Added rte_free() which is useful when you construct a rte and then the circumstances change and you decide not to use it for an update. (Needed for temporary rte's in kernel syncer...)
1998-12-07	KRF_* flags moved to krt.h as they are internal to kernel syncer,	Martin Mares
	fib->pad0,pad1 renamed to x0,x1 and in case of struct net x0 is reserved for kernel syncing as well.
1998-12-06	Removed protocol-specific data in rte for protocol static since no	Martin Mares
	such data ever existed.
1998-12-06	Aesthetic fix for neighbor cache debug dump.	Martin Mares

1998-12-06	Added skeleton of static route protocol.	Martin Mares

1998-12-06	Name cleanups as suggested by Pavel:	Martin Mares
	- cfg_strcpy() -> cfg_strdup() - mempool -> linpool, mp_* -> lp_* [to avoid confusion with memblock, mb_] Anyway, it might be better to stop ranting about names and do some real* work.
1998-12-04	Rip now has configurable per-interface metric (please rewiev), and few	Pavel Machek
	more configurable parameters. To do that, union was added into iface_patt.
1998-11-29	Added configuration of the device internal protocol. This is primarily	Martin Mares
	intended to serve as an example of interface pattern list use. As a side effect, you can disable generating of device routes by disabling this protocol.
1998-11-29	Handle disabled protocol instances.	Martin Mares

1998-11-29	Added functions for manipulating interface name pattern lists:	Martin Mares
	o iface_patt_match(list, iface) -- match interface against list o iface_patts_equal(a, b, c) -- compare whether two pattern lists are equal or not. c(x,y) is called for comparison of protocol-dependent data.
1998-11-29	Allow setting debug value and `disabled' flag in protocol definition.	Martin Mares

1998-11-29	Renamed `DEBUG' symbol to `DEBUGGING' to prevent collisions with token	Martin Mares
	names and include files.
1998-11-27	Oops, forgot to remove a debugging kludge.	Martin Mares

1998-11-27	Trivial 15-line bison excercise: Implemented expressions including	Martin Mares
	user-defined numeric symbols. Whenever possible, use `expr' instead of `NUM' to get full express ion power :-)
1998-11-27	First attempt at protocol configuration (now done only for RIP).	Martin Mares

1998-11-27	Parser fragment for the core. Now handles only router ID setting.	Martin Mares

1998-11-27	Replaced nest/confile.h by conf/conf.h, added a lot of new definitions.	Martin Mares

1998-10-26	Previous fix was wrong.	Martin Mares

1998-10-26	rte_update: Doesn't loop forever when multiple routes point to the same	Martin Mares
	destination.
1998-10-20	RIP now actually talks to itself.	Pavel Machek

1998-10-20	Beware the NULL route, my son... The bugs that bite, the BIRDs that crash :-)	Martin Mares

1998-10-20	Insert/remove hooks return void, not int.	Martin Mares

1998-10-20	Added pointer to network to RTE. The complications with passing NET separately	Martin Mares
	aren't worth 4 bytes per RTE. rte_discard and rte_dump don't need net * as parameter.
1998-10-19	Generate router_id automatically if possible (standard "smallest of local	Martin Mares
	regular interface addresses" rule). Protocols should NOT rely on router_id existence -- when router ID is not available, the router_id variable is set to zero and protocols requiring valid router ID should just refuse to start, reporting such error to the log.
1998-10-19	Fixed generation of device routes for unnumbered point-to-point links.	Martin Mares

1998-10-19	Proto struct now contain (down \| starting \| up) state.	Martin Mares

1998-10-18	o FIB flags now available for FIB users.	Martin Mares
	o struct network: FIB flags used for kernel syncing. o struct network: `next' field deleted (historical relic).
1998-10-18	Preconfig, postconfig and init hooks can be NULL.	Martin Mares

1998-10-18	Split protocol init to building of protocol list and real protocol init.	Martin Mares
	Added kernel route table syncer skeleton.
1998-10-18	Removed global pointer to proto_dev.	Martin Mares

1998-10-18	After contemplating about RIP route timeouts for a long time, I've implemented	Martin Mares
	protocol callbacks for route insertion and deletion from the central table. RIP should maintain its own per-protocol queue of existing routes, scan it periodically and call rte_discard() for routes that have timed out.
1998-10-18	Implemented `route last modified' time.	Martin Mares

1998-10-17	Fixed misleading comment.	Martin Mares

1998-10-17	Each protocol now hears even its own routes and needs to make its own	Martin Mares
	loop detection. This is needed since both RIP and OSPF handle multiple neighbors and they need to redistribute routes learned from each neighbor to the remaining ones.
1998-10-17	Solve chicken-and-egg problems with protocol startup. We now queue all inactive	Martin Mares
	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.
