Description Jeff Bastian 2009-04-24 20:45:41 UTC 
Description of problem:
When trying to build a RHEL 4.7 s390x NIS slave server against a Solaris 10 UltraSPARC NIS master, the 'ypinit -s server' step spits out many errors:

[root@nis-slave ~]# /usr/lib64/yp/ypinit -s nis-master.example.com
We will need a few minutes to copy the data from nis-master.example.com.
Transferring audit_user...
*** glibc detected *** free(): invalid pointer: 0x00000200001a1000 ***
/usr/lib64/yp/ypinit: line 37: 31122 Aborted                 $YPBINDIR/ypxfr -f -h $MASTER -c -d $DOMAIN $map
YPINIT: WARNING: Couldn't exec /usr/lib64/yp/ypxfr -f -h server.example.com -c -d nisarch audit_user

This works fine with RHEL 5.3 s390x NIS slave, so I compared the ypxfr source code in RHEL 4.7 against 5.3 and found there aren't many changes.  I backported those changes and now ypinit works fine.  See the attached patch.


Version-Release number of selected component (if applicable):
ypserv-2.13-19.s390x

How reproducible:
every time

Steps to Reproduce:
1. build a Solaris 10 UltraSPARC NIS master
2. try to build a RHEL 4.7 s390x NIS slave
  
Actual results:
'ypinit -s nis-master.example.com' step fails

Expected results:
ypinit successfully initializes the NIS slave
