491cd43b77 Updated RIP to new neighbor cache semantics. When presented with next hop 
equal to a local address, just ignore the route (as it is usually just an
external route exported by us echoed by some RIP peer), when given an
invalid next hop, moan to the log.

3b0b2cb61f IPv6: Absolutize link-scope addresses of incoming packets.

dc6405d27e Latest changes by Pavel have removed the error messages printed after 
unsuccessful socket open, but replaced them by segmentatio fault!

Grrrrrrrrr.

f7ad556f20 Commented out the `inserting entry which is already there' message since 
it's pretty normal: during feeding of the protocol, a new route can appear
which will be announced normally and then repeated by the feeding process.

898fdd85dc Rip should now reconfigure itself only if needed. 2000-05-16 14:58:06 +00:00
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.

53943a0022 Defined format specifier %M' which behaves as %m', but takes the

Use it in socket hooks where we really shouldn't rely on errno containing

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.

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.

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.
 1999-03-26 21:50:43 +00:00

d1f7eab6b5 Parameter order for the proto->if_notify hook was different in the include
