smbclient tar (create, extract) fails on zSeries when file is over 8GB

This document (7009690) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 11 Service Pack 1

Situation

If the smbclient tar command (smbclient -T options) is used to create an archive larger than 8GB, it will fail and create an invalid tar file.

On a Samba Server, create a test file using dd:
# dd if=/dev/zero of=smbcl.test bs=1M count=9216 or 8192
On the Samba Client, run
# smbclient  //server/share -U uuuu%ppp -I x.x.x.x -Tc xxx.tar

The results are:
count=9216, input size=9663676416, but tar -tvf shows 274911461376
count=8192, input size=8589934592, but tar -tvf shows 33554432

Extracting a 8GB tar file also fails:

# tar -tvf smbltest32.tar

# smbclient //target/share -U user%password -Tx smbltest32.tar

Resolution

The samba update, samba-3.4.3-1.34.1, released February 2012 includes the solution to resolve this problem. Please install the recommended update.
