92f8878cbf Fixes a bug related to multiple IPs and direct protocol.
Multiple IPs in the same IP prefix confuse the direct
protocol and could cause withdrawal of a valid prefix.

Thanks to Dan Rimal for a bugreport.

094d2bdb79 Implements ADD-PATH extension for BGP.
Allows to send and receive multiple routes for one network by one BGP
session. Also contains necessary core changes to support this (routing
tables accepting several routes for one network from one protocol).
It needs some more cleanup before merging to the master branch.

a7f23f581f Implements protocol templates.
Based on the patch from Alexander V. Chernikov.
Extended to support almost all protocols.
Uses 'protocol bgp NAME from TEMPLATE { ... }' syntax.

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

20e94fb85b A change in OSPF and RIP interface patterns.
Allows to add more interface patterns to one common 'options'
section like:

interface "eth3", "eth4" { options common to eth3 and eth4 };

Also removes undocumented and unnecessary ability to specify
more interface patterns with different 'options' sections:

interface "eth3" { options ... }, "eth4" { options ... };

221135d6bf Include "lib/string.h" instead of <string.h>. It should give us bzero()
and other non-portable functions on all systems.

6b9fa32080 Great cleanup of debug messages. LOCAL_DEBUG turned off in most modules,
several debug() calls converted to DBG().

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.

3ea1ba632b Killed protocol->priority. Protocol startup should be clean and hack-free now.
It seems everything still works (except for disable/enable/restart which hangs
sometimes, but it's another story).

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.

8edf2361f9 Cleaned up handling of interface patterns:
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.

4f1a6d27b9 Kill remaining master_table relics in KRT code.
Make all protocols pass routing table to rte_update and rte_discard.

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.

08e2d6259a Removed TOS support. This simplifies many things a lot. 1999-04-12 18:01:07 +00:00

7dc4827c96 Added everything protocols need to know about multiple routing tables,
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.

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.

b2280748ad Introduced protocol priority (all 'normal' protocols should use the
default zero priority). No more "kernel syncer initialized before
device routes" problems.

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).

50d8424ad1 Added configuration of the device internal protocol. This is primarily
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.

a0762910a6 Added pointer to network to RTE. The complications with passing NET separately
aren't worth 4 bytes per RTE.

rte_discard and rte_dump don't need net * as parameter.

c5ffa44759 Skeleton of device route protocol. As it's tightly coupled with our kernel,
it sits here instead of `proto/dev'.
