(ospf_spf_init) Root vertex always creates with 0 cost.
(ospf_spf_add_parent) Remove the buggy V->W cost calculating
code, instead take the new distance as a parameter.
(ospf_nexthop_calculation) Take distance as parameter, so it
can be passed down to add_parent.
(ospf_spf_next) Dont initialise candiate vertex distance,
vertex_new does so already. Pass distance down to
nexthop_calculation (see above).

[zebra] IRDP should ignore non-IPv4 addresses
2007-02-26 Robert Olsson <Robert.Olsson@data.slu.se>
* irdp_main.c: (irdp_send_thread) Skip non-AF_INET addresses,
i.e. do not try interpret IPv6 addresses as IPv4 addresses
to broadcast in IRDP announcements..

[bgpd] Peer delete can race with reconfig leading to crash
2007-02-22 Paul Jakma <paul.jakma@sun.com>
* bgp_fsm.c: (bgp_fsm_change_status) Handle state change into
clearing or greater here. Simpler.
(bgp_event) Clearing state change work moved to previous
* bgp_route.c: (bgp_clear_route_node) Clearing adj-in here
is too late, as it leaves a race between a peer being deleted
and an identical peer being configured before clearing
completes, leading to a crash.
Simplest fix is to clean peers Adj-in up-front, rather than
queueing such work.
(bgp_clear_route_table) Clear peer's Adj-In and Adj-Out
up-front here, rather than queueing such work.
Extensive comment added on the various bits of indexed data
that exist and how they need to be dealt with.
(bgp_clear_route) Update comment.

de-support NetBSD 1.6, and note that FreeBSD 4 is on thin ice.
Update notes on required tool versions Note that autoconf 2.59 is the
standard (even though it's old, 2.60 and 2.61 are pretty recent). For
others, pick releases that are at least 1.5 years old.
Note that GNU awk is required.
Replace update-autotools reference with bootstrap.sh.
(no changelog, doc change only, per GNU coding standards)

remove crufty m4 files from 2004. With the files, autoheader (2.61)
bombs on NetBSD. (Without, all is ok. We may need workarounds, but
first we should identify minimum tool versions and figure out what's
still wrong.)
