f761503760 Fixes RIPng socket and neighbor handling.
RIPng did not really work because of link-local addresses.

Thanks to Roman Hoog Antink for some notes.

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.

52a43ae3b7 Minor changes in addresses.
Mainly changes IA_UNNUMBERED to IA_PEER and adds IA_HOST. Also do not
show broadcast addr in show interfaces. Nobody cares for that.

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).

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 ... };

b21f68b4cd Fix bugs in OSPF MD5 authentication. First bug is that default
values for MD5 password ID changed during reconfigure, Second
bug is that BIRD chooses password in first-fit manner, but RFC
says that it should use the one with the latest generate-from.

It also modifies the syntax for multiple passwords.
Now it is possible to just add more 'password' statements
to the interface section and it is not needed to use
'passwords' section. Old syntax can be used too.

3cb96cd343 The initial sequence number for RIP md5 authentication was always zero.
Bad as when bird e.g. was running for two weeks and then restarted it
would take another two weeks until the peers of this router would accept
data again from this router, as the sequence number would be too low.
Changed to use the the current system time as the starting sequence
number which is a more sane start value.

Martin Mares
28323d9ddb Several minor RIP changes (Pavel, please check as usually):
o  Use FIB_ITERATE_INIT instead of calling the function fit_init()
      which is explictly marked as private in route.h.
   o  When printing trace messages, don't spit out protocol name twice.
   o  Some messages are a bit more verbose.
   o  Added a bunch of FIXME's.
   o  When running in broadcast mode, don't forget to bind the local
      end of the socket to the same broadcast address, so that we don't
      get the broadcasts looped back via different interface. I'm just
      going to look up the same problem for multicasts.

ce1da96ee7 Added commands show route protocol <p>' and show route import <p>' which
show the routing table as exported to the protocol given resp. as returned
from its import control hook.

To get handling of filtered extended attributes right (even in the old
`show route where <filter>' command), the get_route_info hook gets an
attribute list and all protocol specific rte attributes are contained
there as temporary ones. Updated RIP to do that.

Added ea_append() which joins two ea_list's.

Will we ever able to generate packets saying "route 1.2.3.4 using someone else"?

bce8a34b12 Few fixme's fixed in rip (will not crash any more on request for
sending routing table - hopefully).

Next few steps in md5 authentication (not yet complete).

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.

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.
