Pavel Machek 05a845ed8e Avoid segfault 1999-03-02 19:49:22 +00:00
Martin Mares 7972248d5d Netlink module supports interface scan on startup. Working on more. 1999-03-02 18:37:02 +00:00
Martin Mares e35ef181a4 o The if_change_too_big_p change was too high-spirited. Fixed. 
o  Introduced if_find_by_index()
o  Recognizing two types of interface updates: full update (starting with
   if_start_update(), ending with if_end_update(), guaranteed to see
   all existing interfaces) and a partial update (only if_update(),
   usually due to asynchronous interface notifications).
 1999-03-02 18:36:09 +00:00
Martin Mares bcbd8cc3be Interface logic changes: 
o  Introduced IF_LINK_UP flag corresponding to real link state.
o  Allowed addressless interfaces.
o  IF_UP is now automatically calculated and set iff the interface
   is administratively up, has link up and has an IP address assigned.
   It may be IF_IGNORED, though (as in case of the loopback).
o  Any changes which include up/down transition are considered small
   enough to not provoke artificial upping and downing of the interface.
o  When an interface disappears (i.e., it wasn't seen in the last scan),
   we announce this change only once.
o  IF_LOOPBACK implies IF_IGNORE.

Martin Mares 25287d6f7e Don't try to install static routes to disconnected neighbors. 1999-03-02 17:20:07 +00:00
Martin Mares eab0d1e5e5 Latest changes broke out-of-tree compilation. 1999-03-02 16:39:41 +00:00
Pavel Machek 3d8ef0c9ef I just don't like files enclosed in <>. 1999-03-02 13:15:35 +00:00
Martin Mares e834074dd4 If we are compiling with debugging enabled and libefence is available, 
link it to get debugging malloc.
 1999-03-01 22:42:47 +00:00
Martin Mares b982b6db2b Implemented netlink protocol parsing functions. More to come tomorrow. 1999-03-01 22:31:27 +00:00
Martin Mares b4b3b39e20 Added SK_MAGIC type sockets for internal use by system dependent code, 
especially for netlink communication.
 1999-03-01 22:30:33 +00:00
Pavel Machek c748cdb9ec Hopefully ended translating to new interface 1999-03-01 21:18:01 +00:00
Martin Mares bdb95a21a4 Added skeletal version of Linux netlink interface. It doesn't work yet, 
but the framework is there and I'll try finish it soon.
 1999-03-01 20:17:46 +00:00
Martin Mares ea3582a6f6 Include "config.h" instead of "autoconf.h" in all Modules lists to make defines 
in the static portion of configuration includes available as well.
 1999-03-01 20:15:14 +00:00
Martin Mares 1b769b08c1 Renamed struct rtattr to struct rta to make things more consistent and 
avoid namespace clashes with <linux/rtnetlink.h>. Other files should
not be affected since they use 'rta' directly.
 1999-03-01 20:13:54 +00:00
Martin Mares 025d14cd5a Use traditional Unix route/iface interface only when CONFIG_NETLINK 
is not defined. Also moved declarations of Unix iface logic to krt.h.
 1999-03-01 19:05:58 +00:00
Martin Mares 12be9b8c18 Pruned the TODO list. 1999-03-01 17:51:29 +00:00
Pavel Machek 293e313ec9 More rip fixes (config data moved to struct rip_proto_config), still 
not tested.
 1999-02-15 13:34:43 +00:00
Martin Mares b5fe3dc21c Cleaned up TODO file. 
That's all for today, midnight gets closer.
 1999-02-13 22:13:04 +00:00
Martin Mares 45090fecd9 Synced example config with new options. 1999-02-13 22:02:21 +00:00
Martin Mares d88e99a92a Implemented static device routes. 
Expect for reconfiguration issues, the static protocol is complete now.
 1999-02-13 21:59:48 +00:00
Martin Mares d1f7eab6b5 Parameter order for the proto->if_notify hook was different in the include 
file and different in reality. Decided to use the same order as we do
for proto->rt_notify (i.e., first new value and second the old one).
 1999-02-13 21:58:53 +00:00
Martin Mares 726141746b '#' comments in config files are equivalent to end of line, therefore 
also to implicit ';'.
 1999-02-13 21:34:33 +00:00
Martin Mares 5996da6a1d Implemented garbage collection of routing tables to delete orphaned network 
nodes having no routes attached. Such cleanup must be done from event handler
since most functions manipulating the routing tables expect network entries
won't disappear from under their hands and it's also probably faster when
done asynchronously.
 1999-02-13 21:29:01 +00:00
Martin Mares f4a0a64e02 Static protocol doesn't need any shutdown function. Everything gets 
disposed by the core: neighbors, rte's, etc's...
 1999-02-13 21:00:25 +00:00
Martin Mares 3fb4ca2ce2 Don't send any neighbor notifications to protocols being flushed. 1999-02-13 20:57:47 +00:00
Martin Mares 783f8b689a When protocols go down, prune the neighbor list. 1999-02-13 20:55:08 +00:00
Martin Mares 013a9b91fe When shutting down, remove all routes (except for RTS_INHERIT and RTS_DEVICE 
routes) from kernel routing tables unless the "persist" switch is set.
 1999-02-13 20:46:03 +00:00
Martin Mares 0a2e9d9f56 Moved sanity check of protocol state during annoucements to rte_announce. 1999-02-13 20:19:24 +00:00
Martin Mares f4aabcee62 Perform gracious shutdown upon receipt of SIGTERM. Finally we can 
test the whole protocol shutdown code... :)
 1999-02-13 20:15:36 +00:00
Martin Mares 7f3d1a0850 Squashed one bug in timing of route scans. 1999-02-13 19:57:19 +00:00
Martin Mares 4c9dd1e4b9 Synchronize signals to the main select/event/timer loop. 
Parse command line options.
 1999-02-13 19:43:21 +00:00
Martin Mares 1a54b1c6ac Implemented real cleanup and pruning of routing table on protocol shutdown. 1999-02-13 19:15:28 +00:00
Martin Mares ab749558a2 Pass new argument to FIB_ITERATE_END. 1999-02-13 19:14:16 +00:00
Martin Mares 2569bc4073 Fixed bug in FIB_ITERATE_END: it assumed the control variable is named 
"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 19:13:51 +00:00
Martin Mares 4e9498cbb1 config->router_id works again. 1999-02-13 18:42:00 +00:00
Martin Mares 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.
 1999-02-11 22:59:06 +00:00
Martin Mares 14dea0ed25 Run the event queue before writing SIGUSR dumps. 1999-02-11 22:51:15 +00:00
Martin Mares 64011f898c struct proto again contains instance name (a copy of proto->cf->name). 1999-02-11 22:45:54 +00:00
Martin Mares 3b15402fd4 Grrr, forgot to commit the event routines themselves :| 1999-02-11 22:18:36 +00:00
Martin Mares e8f73195fa Added simple event scheduling system to avoid recursive calling 
of various callbacks.

Events are just another resource type objects (thus automatically freed
and unlinked when the protocol using them shuts down). Each event can
be linked in at most one event list. For most purposes, just use the
global event list handled by the following functions:

	ev_schedule	Schedule event to be called at the next event
			scheduling point. If the event was already
			scheduled, it's just re-linked to the end of the list.
	ev_postpone	Postpone an already scheduled event, so that it
			won't get called. Postponed events can be scheduled
			again by ev_schedule().

You can also create custom event lists to build your own synchronization
primitives. Just use:

	ev_init_list	to initialize an event list
	ev_enqueue	to schedule event on specified event list
	ev_postpone	works as well for custom lists
	ev_run_list	to run all events on your custom list
	ev_run		to run a specific event and dequeue it

Pavel Machek edf62ba13f Propagate depend into all subdirectories; make rip compile after 
latest mj's changes.
 1999-02-08 22:50:32 +00:00
Martin Mares ed245f967f Synced Linux sysdeps to new interface. 1999-02-05 21:39:21 +00:00
Martin Mares 10d807d000 Synced kernel interface to new interface. 1999-02-05 21:38:50 +00:00
Martin Mares e9e3dc2659 Modified static router to use new interface. 1999-02-05 21:38:22 +00:00
Martin Mares 31b3e1bbf5 Implemented new configuration/reconfiguration interface and defined protocol 
state machines. Full explanation will follow soon.
 1999-02-05 21:37:34 +00:00
Martin Mares c4c63eecc3 Added several parentheses to MIN/MAX macros. 1999-02-05 21:29:19 +00:00
Pavel Machek 292099d55f Few fixes in parsing of filters 1999-02-03 12:28:16 +00:00
Martin Mares 294c182eb1 Replaced the old ugly ipv6 compilation hack by a conditional in Modules. 1999-01-23 21:08:59 +00:00
Martin Mares 2c2f67bd83 Filter all `Modules' files through C preprocessor, so that they can 
reference BIRD configuration.

By the way: Do you know GCC by default does `#define unix 1'?
 1999-01-23 21:08:36 +00:00
Pavel Machek ca3d562b24 filters_init() renamed to filters_postconfig(). 1999-01-15 18:13:55 +00:00
