1999-08-03Protocol engine bug fixes:Martin Mares
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).
1999-08-03Cleaned up handling of interface patterns:Martin Mares
o Parsing of interface patterns moved to generic code, introduced this_ipatt which works similarly to this_iface. o Interface patterns now support selection by both interface names and primary IP addresses. o Proto `direct' updated. o RIP updated as well, it also seems the memory corruption bug there is gone.

1999-05-31Added extended attributes for rip.Pavel Machek
1999-05-31Added extra argument to rt_update hook which contains a pointer to theMartin Mares
temporary attribute list.
1999-05-31Added PASSIVE option to paswwords.Pavel Machek
1999-05-26Change format of passwords (less ;'s) and fix password.h to allowPavel Machek
multiple inclusions.
1999-05-26Skeleton for password handling, currently I only build structures andPavel Machek
do nothing more advanced for them
1999-05-17Kill remaining master_table relics in KRT code.Martin Mares
Make all protocols pass routing table to rte_update and rte_discard.
1999-05-17From now we support multiple tables. The master_table variable isMartin Mares
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.
1999-05-07Netlink support for secondary interface addresses.Martin Mares
1999-05-06I rewrote the interface handling code, so that it supports multipleMartin Mares
addresses per interface (needed for example for IPv6 support). Visible changes: o struct iface now contains a list of all interface addresses (represented by struct ifa), iface->addr points to the primary address (if any). o Interface has IF_UP set iff it's up and it has a primary address. o IF_UP is now independent on IF_IGNORED (i.e., you need to test IF_IGNORED in the protocols; I've added this, but please check). o The if_notify_change hook has been simplified (only one interface pointer etc.). o Introduced a ifa_notify_change hook. (For now, only the Direct protocol does use it -- it's wise to just listen to device routes in all other protocols.) o Removed IF_CHANGE_FLAGS notifier flag (it was meaningless anyway). o Updated all the code except netlink (I'll look at it tomorrow) to match the new semantics (please look at your code to ensure I did it right). Things to fix: o Netlink. o Make krt-iface interpret "eth0:1"-type aliases as secondary addresses.
1999-04-12Removed TOS support. This simplifies many things a lot.Martin Mares
1999-04-05Routing table core changes to support full route filtering:Martin Mares
o Introduced rte_cow() which should be used for copying on write the rte's in filters. Each rte now carries a flag saying whether it's a real route (possessing table linkage and other insignia) or a local copy. This function can be expected to be fast since its fast-path is inlined. o Introduced rte_update_pool which is a linear memory pool used for all temporary data during rte_update. You should not reference it directly -- instead use a pool pointer passed to all related functions. o Split rte_update to three functions: rte_update The front end: handles all checking, inbound filtering and calls rte_recalculate() for the final version of the route. rte_recalculate Update the table according to already filtered route. rte_announce Announce routing table changes to all protocols, passing them through export filters and so on. The interface has _not_ changed -- still call rte_update() and it will do the rest for you automagically. o Use new filtering semantics to be explained in a separate mail.
1999-04-05Added some new protocol hooks (look at the comments for better explanation):Martin Mares
make_tmp_attrs Convert inline attributes to ea_list store_tmp_attrs Convert ea_list to inline attributes import_control Pre-import decisions
1999-04-05Changed syntax of attaching filters to protocols to hopefully the finalMartin Mares
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 :)).
1999-04-03More changes to the kernel syncer.Martin Mares
o Now compatible with filtering. o Learning of kernel routes supported only on CONFIG_SELF_CONSCIOUS systems (on the others it's impossible to get it semantically correct). o Learning now stores all of its routes in a separate fib and selects the ones the kernel really uses for forwarding packets. o Better treatment of CONFIG_AUTO_ROUTES ports. o Lots of internal changes.
1999-04-03Added new protocol hook for dumping of protocol-dependent routeMartin Mares
attributes. Please implement in all protocols.
1999-03-29Clarify resource dumps and include them in the main debugging dump.Martin Mares
1999-03-29After today's lengthy discussions about filter syntax, let's clean upMartin Mares
whitespace/semicolon rules for whole config file: o All non-zero amounts of whitespace are equivalent to single space (aka `all the whitespace has been born equal' ;-)). o Comments count as whitespace. o Whitespace has no syntactic signifance (it can only separate lexical elements). o Consequence: line ends are no longer treated as `;'s. o Every declaration must be terminated by an explicit `;' unless or by a group enclosed in `{' and `}'.
1999-03-26Added everything protocols need to know about multiple routing tables,Martin Mares
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.
1999-03-26Moved to a much more systematic way of configuring kernel protocols.Martin Mares
o Nothing is configured automatically. You _need_ to specify the kernel syncer in config file in order to get it started. o Syncing has been split to route syncer (protocol "Kernel") and interface syncer (protocol "Device"), device routes are generated by protocol "Direct" (now can exist in multiple instances, so that it will be possible to feed different device routes to different routing tables once multiple tables get supported). See doc/bird.conf.example for a living example of these shiny features.
1999-03-26Allow different instances of the same protocol with identical preferences.Martin Mares
1999-03-26Slightly better generator of default protocol instance names.Martin Mares
1999-03-26Don't try to manipulate neighbor lists for copied interface structures.Martin Mares
This avoids few nasty references to free memory.
1999-03-17rte_update: Check sanity of incoming entries. Throw out (and log) all routesMartin Mares
to bogus prefixes and non-local routes to host scope addresses.
1999-03-17Allow input and output filters (only accept/reject style as we didn't defineMartin Mares
modifying filters yet) to be attached to protocol instances.
1999-03-17Removed the `rta_same' hook since it's no longer needed (all protocolsMartin Mares
needing some local information should use extended attrs and cached rta's).
1999-03-17Implemented extended route attributes and all related functions.Martin Mares
1999-03-09Yes, joining the crew. Sorry for being late. Added dummy functions for OSPF.Ondrej Filip
1999-03-04KRT: Implemented asynchronous route / interface state notificationsMartin Mares
(via Netlink). Tweaked kernel synchronization rules a bit. Discovered locking bug in kernel Netlink :-) Future plans: Hunt all the bugs and solve all the FIXME's.
1999-03-04Initialize allocated struct proto :-)Martin Mares
1999-03-03EFence helped to find using of already free rte's in rt_prune().Martin Mares
1999-03-03Fix several things I broke today.Martin Mares
1999-03-03Added a hack forcing protocols with priority>0 to be started upMartin Mares
immediately. Grrr, need to find a real solution some day.
1999-03-03Introduced protocol priority (all 'normal' protocols should use theMartin Mares
default zero priority). No more "kernel syncer initialized before device routes" problems.
1999-03-02o The if_change_too_big_p change was too high-spirited. Fixed.Martin Mares
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).
1999-03-02Interface logic changes:Martin Mares
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.
1999-03-01Renamed struct rtattr to struct rta to make things more consistent andMartin Mares
avoid namespace clashes with <linux/rtnetlink.h>. Other files should not be affected since they use 'rta' directly.
1999-02-13Parameter order for the proto->if_notify hook was different in the includeMartin Mares
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).
1999-02-13Implemented garbage collection of routing tables to delete orphaned networkMartin Mares
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.
1999-02-13Don't send any neighbor notifications to protocols being flushed.Martin Mares
1999-02-13When protocols go down, prune the neighbor list.Martin Mares
1999-02-13Moved sanity check of protocol state during annoucements to rte_announce.Martin Mares
1999-02-13Perform gracious shutdown upon receipt of SIGTERM. Finally we canMartin Mares
test the whole protocol shutdown code... :)
1999-02-13Implemented real cleanup and pruning of routing table on protocol shutdown.Martin Mares
1999-02-13Fixed bug in FIB_ITERATE_END: it assumed the control variable is namedMartin 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.
1999-02-13config->router_id works again.Martin Mares
1999-02-11Real implementation of protocol state machines. Delayed startup/shutdownMartin Mares
should work now. Initial feeding of protocols by interfaces/routes is done from the event queue to prevent unwanted recursion.
1999-02-11struct proto again contains instance name (a copy of proto->cf->name).Martin Mares
