cfe34a316e Implements hostcache and recursive next hops.
Hostcache is a structure for monitoring changes in a routing table that
is used for routes with dynamic/recursive next hops. This is needed for
proper iBGP next hop handling.

002b642318 Fixes bug on Linux 2.4.x - kernel sync does not work until restart of kernel protocol.
Which was, actually, a bug in timers - on older kernel, monotonic timer
is missing and the other implementation started with now == 0, which
collides with usage 0 as a special value in timer->expires field.

c429d4a4ba Restrict export of device routes to the kernel protocol.
In usual configuration, such export is already restricted
with the aid of the direct protocol but there are some
races that can circumvent it. This makes it harder to
break kernel device routes. Also adds an option to
disable this restriction.

53434e44a9 Better flushing of interfaces.
When device protocol goes down, interfaces should be flushed
asynchronously (in the same way like routes from protocols are flushed),
when protocol goes to DOWN/HUNGRY.

This fixes the problem with static routes staying in kernel routing
table after BIRD shutdown.

ff2857b03d Many changes in (mainly) kernel syncers.
- BSD kernel syncer is now self-conscious and can learn alien routes
- important bugfix in BSD kernel syncer (crash after protocol restart)
- many minor changes and bugfixes in kernel syncers and neighbor cache
- direct protocol does not generate host and link local routes
- min_scope check is removed, all routes have SCOPE_UNIVERSE by default
- also fixes some remaining compiler warnings

dca75fd7c2 Removes phantom protocol from the pipe design.
It seems that by adding one pipe-specific exception to route
announcement code and by adding one argument to rt_notify() callback i
could completely eliminate the need for the phantom protocol instance
and therefore make the code more straightforward. It will also fix some
minor bugs (like ignoring debug flag changes from the command line).

ea89da381f Workaround for stupid callback scheduler.
There is no reak callback scheduler and previous behavior causes
bad things during hard congestion (like BGP hold timeouts).

Smart callback scheduler is still missing, but main loop was
changed such that it first processes all tx callbacks (which
are fast enough) (but max 4* per socket) + rx callbacks for CLI,
and in the second phase it processes one rx callback per
socket up to four sockets (as rx callback can be slow when
there are too many protocols, because route redistribution
is done synchronously inside rx callback). If there is event
callback ready, second phase is skipped in 90% of iterations
(to speed up CLI during congestion).

1567edea8d Bugfix for routing table breaking bug.
Here is a patch fixing a bug that causes breakage of a local routing
table during shutdown of Bird. The problem was caused by shutdown
of 'device' protocol before shutdown of 'kernel' protocol.  When
'device' protocol went down, the route (with local network prefix)
From different protocol (BGP or OSPF) became preferred and installed
to the kernel routing table. Such routes were broken (like
192.168.1.0/24 via 192.168.1.2). I think it is also the cause
of problem reported by Martin Kraus.

The patch disables updating of kernel routing table during shutdown of
Bird. I am not sure whether this is the best way to fix it, I would
prefer to forbid 'kernel' protocol to overwrite routes with
'proto kernel'.

The patch also fixes a problem that during shutdown sometimes routes
created by Bird remained in the kernel routing table.

4da25acb0a Cleaned up sk_reallocate() and friends.
Also, removed the `if (s)' test, because I believe that as the whole
socket interface doesn't accent NULL pointers, sk_reallocate() shouldn't
be the only exception.

(thanks to Andreas for the original idea)
2004-05-31 22:00:18 +00:00
Martin Mares
38a608c55a Rewritten the I/O loop. All socket operations are now safe, meaning that
you can delete the socket from anywhere in the hooks and nothing should break.
Also, the receive/transmit buffers are now regular xmalloc()'ed buffers,
not separate resources which would need shuffling around between pools.

sk_close() is gone, use rfree() instead.

5f2a6a9ff3 Fix handling on full pipe to client in bird. Prevent packet overflows
for even only medium sized route table output. Fix a strange garbled
output problem in the client. The latter seems to be caused by some
library doing tcflush while there is still command output pending. So
the best fix here is to do fflush and then tcdrain. Note that this
problem occurs only under certain load situations and is not too easy to
reproduce.

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.

Martin Mares
6a636392d3 Rewrote interface type detection logic. The `unnumbered' flag is now per
address, not per interface (hence it's ifa->flags & IA_UNNUMBERED) and
should be set reliably. IF_MULTIACCESS should be fixed now, but it isn't
wise to rely on it on interfaces configured with /30 prefix.
2000-02-29 23:19:52 +00:00
Martin Mares
9fac310d1a Put client on a stony ground. The whole client is going to be system-specific
(the current version UNIX-specific) anyway, so it's useless to try splitting it
to sysdep and generic part. Instead of this, configure script decides (based on
system type and user's wish) what (if any) client should be built and what
autoconfiguration it requires. Also, the client provides its own die/bug/...
functions.

d272fe22dd Separated `official protocol names' used in status dumps from name templates
used for automatic generation of instance names.

	protocol->name is the official name
	protocol->template is the name template (usually "name%d"),
		should be all lowercase.

Updated all protocols to define the templates, checked that their configuration
grammar includes proto_name which generates the name and interns it in the
symbol table.

f545d38707 Added universal locking mechanism which will solve problems
with protocols wanting to use the same port on the same interface
during reconfiguration time.

How to use locks: In the if_notify hook, just order locks for the
interfaces you want to work with and do the real socket opening after the
lock hook function gets called. When you stop using the socket, close
it and rfree() the lock.

Please update your protocols to use the new locking mechanism.

Martin Mares
dce267832a Basic support for IPv6. The system-dependent part doesn't work yet,
but the core routines are there and seem to be working.

   o  lib/ipv6.[ch] written
   o  Lexical analyser recognizes IPv6 addresses and when in IPv6
      mode, treats pure IPv4 addresses as router IDs.
   o  Router ID must be configured manually on IPv6 systems.
   o  Added SCOPE_ORGANIZATION for org-scoped IPv6 multicasts.
   o  Fixed few places where ipa_(hton|ntoh) was called as a function
      returning converted address.

a2697f02ac Netlink support for secondary interface addresses. 1999-05-07 13:46:16 +00:00
Martin Mares
9a158361da I rewrote the interface handling code, so that it supports multiple
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.

Martin Mares
36154beb70 Use SO_BINDTODEVICE if we're using old multicast API (i.e., struct ip_mreq
and not ip_mreqn). This should get multicasts on unnumbered PtP links work.
1999-04-14 11:21:02 +00:00
Martin Mares
01bd7759b2 Ignore alias interfaces (some day, we will treat them as pure secondary
interface addresses).
1999-04-12 18:07:05 +00:00
Martin Mares
08e2d6259a Removed TOS support. This simplifies many things a lot. 1999-04-12 18:01:07 +00:00
Martin Mares
61fb537c62 Use struct ip_mreqn' instead of struct ip_mreq' for multicast
operations on 2.1/2.2 kernels. This allows passing of real interface
indexes instead of referencing interfaces by their IP addresses which
fails badly in presence of unnumbered interfaces.

Unfortunately, this structure is not visible with glibc 2.0 as it provides
its own networking headers :-(  Both libc5 and glibc 2.1 should be OK.

c10421d3d4 More changes to the kernel syncer.
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.
1999-04-03 13:05:18 +00:00

1127ac6ec7 Cleaned up system configuration files -- removed few obsolete parameters,
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.
1999-03-27 22:51:05 +00:00
Martin Mares
7e5f5ffdda Moved to a much more systematic way of configuring kernel protocols.
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.

2253c9e239 Although there are still heaps of FIXME's, Netlink works.
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 :)).

Martin Mares
7a2105becd Use dmalloc instead of EFence when available (dmalloc has lot of improvements
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().

2d14045224 Rewrote the kernel syncer. The old layering was horrible.
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.

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
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

49e7e5ee0b New makefiles. Includes support for out-of-source-tree builds. 1999-01-10 00:18:32 +00:00
Martin Mares
2f9bcf9713 First step of "autoconfization". Created a configure script which
guesses most system-dependent parameters and determines name of system
configuration file (sysdep/cf/...) with the remaining ones.

To compile BIRD, you now need to do:

	autoconf		# Create configure from configure.in
	./configure		# Run configure script
	make			# Compile everything

Configuration files:

	sysdep/config.h		Master config file
	sysdep/autoconf.h	Parameters determined by configure script
	sysdep/cf/*.h		Fixed system configuration we're unable
				to guess.

Makefiles are still the original ones, but this will change soon.

08c69a7720 die() -> bug() where appropriate. 1998-12-20 14:27:37 +00:00
Martin Mares
98e87c8628 Finer grained logging levels:
#define L_DEBUG "\001"   /* Debugging messages */
#define L_INFO "\002"    /* Informational messages */
#define L_WARN "\003"    /* Warnings */
#define L_ERR "\004"     /* Errors */
#define L_AUTH "\005"    /* Authorization failed etc. */
#define L_FATAL "\006"   /* Fatal errors */
#define L_TRACE "\002"   /* Protocol tracing */
#define L_INFO "\003"    /* Informational messages */
#define L_REMOTE "\004"  /* Remote protocol errors */
#define L_WARN "\004"    /* Local warnings */
#define L_ERR "\005"     /* Local errors */
#define L_AUTH "\006"    /* Authorization failed etc. */
#define L_FATAL "\007"   /* Fatal errors */
#define L_BUG "\010"     /* BIRD bugs */

Introduced bug() which is like die(), but with level L_BUG. Protocols
should _never_ call die() as it should be used only during initialization
and on irrecoverable catastrophic events like out of memory.

Also introduced ASSERT() which behaves like normal assert(), but it calls
bug() when assertion fails. When !defined(DEBUGGING), it gets ignored.

8e66a0ebb9 Hopefully finished kernel syncer (krt) rewrite:
o  Interface syncing is now a part of krt and it can have configurable
     parameters. Actually, the only one is scan rate now :)
  o  Kernel routing table syncing is now synchronized with interface
     syncing (we need the most recent version of the interface list
     to prevent lots of routes to non-existent destinations from
     appearing). Instead of its own timer, we just check if it's
     route scan time after each iface list scan.
  o  Syncing of device routes implemented.
  o  CONFIG_AUTO_ROUTES should control syncing of automatic device routes.
  o  Rewrote krt_remove_route() to really remove routes :)
  o  Better diagnostics.
  o  Fixed a couple of bugs.

7d83290780 Generate router_id automatically if possible (standard "smallest of local
regular interface addresses" rule).

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.
