1999-03-29#define NULL if not defined by system includes.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 `}'.
1999-03-27Cleaned up system configuration files -- removed few obsolete parameters,Martin Mares
documented the remaining ones (sysdep/cf/README). Available configurations: o linux-20: Old Linux interface via /proc/net/route (selected by default on pre-2.1 kernels). o linux-21: Old Linux interface, but device routes handled by the kernel (selected by default for 2.1 and newer kernels). o linux-22: Linux with Netlink (I play with it a lot yet, so it isn't a default). o linux-ipv6: Prototype config for IPv6 on Linux. Not functional yet.
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 compile OSPF by default.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.
1999-03-24Removed our declaration of RTPROT_BIRD since Alexey has assignedMartin Mares
us a real protocol number in 2.2.4 kernel.
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.
1999-03-17A couple of filter tweaks:Martin Mares
o Introduced struct filter which serves as an external reference to filter. Using struct symbol for this is unwise since it doesn't allow extra information attached to the filter and it also forces all filters to be named. o Implemented config rule 'filter' which matches either named filter or an embedded unnamed filter (`{ <filter> }'). o Fixed totally bogus comment at the top of filter.h. o Added a missing prototype for f_run() to filter.h.
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
1999-03-17Initialize pointers to functions so that code is actually alive.Pavel Machek
1999-03-17Compilation fix for mj.Pavel Machek
1999-03-17Don't segfault on unknown interface.Pavel Machek
1999-03-17accept & reject should now workPavel Machek
1999-03-09Yes, joining the crew. Sorry for being late. Added dummy functions for OSPF.Ondrej Filip
1999-03-09Resolved conflicts, you no longer need to wrap constants in const()Pavel Machek
1999-03-09Added '=' to operator listPavel Machek
1999-03-08Filters are now a tiny bit stronger (if is actually working ;-)Pavel Machek
1999-03-04Fixed processing of !krt_capable() routes. Converted device route decisionsMartin Mares
to the krt_capable mechanism as well.
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.
1999-03-04Although there are still heaps of FIXME's, Netlink works.Martin Mares
To build BIRD with Netlink support, just configure it with ./configure --with-sysconfig=linux-21 After it will be tested well enough, I'll probably make it a default for 2.2 kernels (and rename it to linux-22 :)).
1999-03-04Converted some mb_alloc/bzero pairs to mb_allocz.Martin Mares
1999-03-04Initialize allocated struct proto :-)Martin Mares
1999-03-04Use dmalloc instead of EFence when available (dmalloc has lot of improvementsMartin Mares
over EFence and also hopefully smaller memory overhead, but sadly it's non-free for commercial use). If the DMALLOC_OPTIONS environment variable is not set, switch on `reasonable' checks by default. Also introduced mb_allocz() for cleared mb_alloc().
1999-03-03Netlink scans routes...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.
1999-03-03Rewrote the kernel syncer. The old layering was horrible.Martin Mares
The new kernel syncer is cleanly split between generic UNIX module and OS dependent submodules: - krt.c (the generic part) - krt-iface (low-level functions for interface handling) - krt-scan (low-level functions for routing table scanning) - krt-set (low-level functions for setting of kernel routes) krt-set and krt-iface are common for all BSD-like Unices, krt-scan is heavily system dependent (most Unices require /dev/kmem parsing, Linux uses /proc), Netlink substitues all three modules. We expect each UNIX port supports kernel routing table scanning, kernel interface table scanning, kernel route manipulation and possibly also asynchronous event notifications (new route, interface state change; not implemented yet) and build the KRT protocol on the top of these primitive operations.
1999-03-03Introduced protocol priority (all 'normal' protocols should use theMartin Mares
default zero priority). No more "kernel syncer initialized before device routes" problems.
1999-03-02Add interface for running filters (please comment!), avoid bison warningsPavel Machek
1999-03-02Avoid segfaultPavel Machek
1999-03-02Netlink module supports interface scan on startup. Working on more.Martin Mares
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.
1999-03-02Don't try to install static routes to disconnected neighbors.Martin Mares
1999-03-02Latest changes broke out-of-tree compilation.Martin Mares
1999-03-02I just don't like files enclosed in <>.Pavel Machek
1999-03-01If we are compiling with debugging enabled and libefence is available,Martin Mares
link it to get debugging malloc.
1999-03-01Implemented netlink protocol parsing functions. More to come tomorrow.Martin Mares
1999-03-01Added SK_MAGIC type sockets for internal use by system dependent code,Martin Mares
especially for netlink communication.
1999-03-01Hopefully ended translating to new interfacePavel Machek
1999-03-01Added skeletal version of Linux netlink interface. It doesn't work yet,Martin Mares
but the framework is there and I'll try finish it soon.
1999-03-01Include "config.h" instead of "autoconf.h" in all Modules lists to make definesMartin Mares
in the static portion of configuration includes available as well.
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.
