Description dh 2000-11-14 16:30:01 UTC

dynamic dns updates seem to break named

Nov 14 16:11:11 server /kernel: pid 13798 (named), uid 0: exited on signal 11 (core dumped)

Fix: 

none
How-To-Repeat: freebsd box:
with named and dhcp

windows box:
using the freebsd box for name resolution and dhcp

on the windows box:
from MSDOS run 'winipcfg'
then press the "renew" button

at that exact moment a tail -f /var/log/messages
will show you named getting sig 11 and dumping core

Comment 1 dh 2000-11-16 13:20:07 UTC

we've cvsuped our userland back to '*default date=2000.10.09.00.00.00"
(before that new named was put in)
and that 'fixes' it

Modified files:        (Branch: RELENG_4) 
contrib/bind/bin/named ns_update.c 
Log: 
Fix CVS slippage from a merge.  Somehow these two lines remained 
when they were supposed to be superceded by the following lines. Odd. 

Anyway, this fixes the coredumps some people have been experiencing 
when a dynamic update was triggered and ifp got to be NULL somehow.
