simplifies some code because it is possible to get the local AS from the
peer struct. Local AS needs more patching to work correctly though.

track multipath routes. Code is mostly stolen from similar fixes to ospfd but
a bit different as this kroute.c implementation is more complex because of
additional task (nexthop verification for example).
This change and the similar ospfd change were desperatly needed on larger
complex network setups which tended to end up in situation where the kernel
had a different oppinion about routing than the daemon. Now the situation
should be a lot better.

the peer data. makes bgpctl display code independent from timer
implementation internals. only running timers are displayed now, stopped
ones are skipped.

yylex implementation and the code which interacts with yylex. this also
brings the future potential for include support to all of the parsers.
in the future please do not silly modifications to one of these files
without checking if you are de-unifying the code.
checked by developers in all these areas.

that unfortunately means we cannot use 0 for "unset".

Additionally our as4byte support is based on draft-ietf-idr-as4bytes-13.

are now 4-byte instead of the old 2-byte numbers. The only exception are
communities because they can not be switched. The RDE will inflate and deflate
the ASPATH and AGGREGATOR attributes on demand and create the NEW_ASPATH and
NEW_AGGREGATOR field whenever needed. Both old and new stile sessions are
supported and can be mixed. Currently new stile sessions with the 4-byte AS
number capability turned on are only enabled if one of the AS numbers involved
is a 4-byte one.
This is based on an initial diff by Geoff Huston gih (at) apnic (dot) net
Cleanup, testing and bug-fixes by myself (via AS 3.10).
Currently mrt table dumps are producing incompatible output this will be fixed
afterwards -- this diff is already big enough.

a few things we actually never realy cared about.
OK henning@
|
|
|

- dedicated pipe between the SE and the RDE for control messages
- restartable RB tree dumps in the RDE
- queuing limits both in the SE and RDE
The result is a dramatic decrease of memory consumption on operations like
bgpctl show rib. Previously all messages where first stored in the RDE
then passed to the SE where they got queued in case bgpctl was not fast enough.
Now only a small number of messages is generated and passed to the SE and
the SE has an additional limit instead of acting like an infinite buffer.
Without this the bgpd on bgpd.networx.ch would not survive a single minute.
looks good henning@

draft-ietf-idr-restart. Do not announce actual restart capabilities,
so that this only serves as indicator that we are capable of sending
and receiving the End-of-RIB marker.
leave disabled for now, since the code to actually send the EoR-marker
is currently ifdef'd out (to be fixed soon) and we wanna play safe for
4.0. and juniper doesn't support that capability (which is not a problem
per se) and at the same time has its capability negotiation code completely
fucked up, if a capability is rejected they don't indicate WHICH capability
they reject (which makes that a problem, tho still a small one and we cope).

sessions can be configured to modify the carp demotion counter for a
given interface group (usually, "carp", which has all carp interfaces)
when the session is not established. once the session is established for
60 seconds, the demotion is cleared.
this, used correctly, can prevent a bgpd-box which lost all sessions (and
thus has no routes) to be carp master, while the backup has sessions.

as soon as F_ORIGINAL come the counters would no longer be correct and in the

The default filter_sets are converted into match filter rules that get
evaluated first. Simplifies code massively -- mainly the config reload
part -- and makes softreconfig out a piece of cake. "get it in" henning@
