Description Patrik Kis 2014-12-03 10:32:35 UTC 
Description of problem:
In multilib environment if booth architectures are installed the native architecture of the machine should appear on the disk (e.g. on x86_64 machine if booth i686 and x86_64 version of a package are installed the x86_64 versions of binaries and libraries should be installed). This can be broken under certain circumstances.

Version-Release number of selected component (if applicable):
rpm-4.11.1-23.el7

How reproducible:
always

Steps to Reproduce:

[root@rhel70 new]# uname -p
x86_64
[root@rhel70 new]# rpm -qa krb5\*
krb5-libs-1.12.2-8.el7.i686
krb5-libs-1.12.2-8.el7.x86_64
[root@rhel70 new]# rpm -ivh krb5-server-1.12.2-8.el7.*.rpm krb5-devel-1.12.2-8.el7.*.rpm

Additional info:

The bug demonstrated itself because by mistake booth arch od krb5-server were distributed, what is a mistake. In the past only 2 krb5-devel and 1 krb5-server packages were released, and in that case the problem does not appear. In any case, this bug should be fixed also on rpm level.

Comment 1 Karel Srot 2015-04-02 07:27:40 UTC 
Florian,
shouldn't rpm report a file conflict in such case?
Comment 2 Florian Festi 2015-04-02 13:43:22 UTC 
No, with multilib files with color=1 (typically 32 bit binaries) are silently overwritten by files with color=2 (typically 64 bit binaries). We already fixed this in 6.7. See #1170124.
Comment 4 Ľuboš Kardoš 2015-04-02 14:16:05 UTC 
One note why there is no conflict here. Let's have a look at file /usr/bin/sclient. We have this file in four packages (krb5-devel.i686, krb5-devel.x86_64, krb5-server.i686, krb5-server.x86_64) so we have following six combinations (4 choose 2 = 6).

/usr/bin/sclient(krb5-devel.i686) vs usr/bin/sclient(krb5-server.i686) -> the same content -> no file conflict
/usr/bin/sclient(krb5-devel.x86_64) vs usr/bin/sclient(krb5-server.x86_64) -> the same content -> no file conflict

/usr/bin/sclient(krb5-devel.i686) vs usr/bin/sclient(krb5-devel.x86_64) -> different colors -> no file conflict
/usr/bin/sclient(krb5-server.i686) vs usr/bin/sclient(krb5-server.x86_64) -> different colors -> no file conflict

/usr/bin/sclient(krb5-devel.i686) vs usr/bin/sclient(krb5-server.x86_64) -> different colors -> no file conflict
/usr/bin/sclient(krb5-server.i686) vs usr/bin/sclient(krb5-devel.x86_64) -> different colors -> no file conflict

So there is no conflict and 64bit variant of file /usr/bin/sclient should be installed.
