Bug 1099148

Reason this is showing up is that the redhat-rpm-config package installs the file '/usr/lib/rpm/redhat/macros' which contains macros that result in RPMs not compatible with RHEL5.


$ rpm -qf /usr/lib/rpm/redhat/macros 
redhat-rpm-config-9.0.3-42.el6.noarch


cat /usr/lib/rpm/redhat/macros
<snip>
# Use SHA-256 for FILEDIGESTS instead of default MD5
%_source_filedigest_algorithm 8
%_binary_filedigest_algorithm 8

# Use XZ compression for binary payloads
%_binary_payload w2.xzdio
<snip>


The change to SHA-256 and use of XZ for compression are the issues we have seen.

Yes, RHEL 5 is supported in RHUI 3 until RHEL 5 goes EOL. 
The core use case is that a RHEL 5 client will need to be able to get update from RHUI 3 when the partner migrates to RHUI 3.

Fixing version

I can still reproduce the problem with RHUI 3. The generated package has the following dependencies:

# rpm -qpR rhel5client-2.0/build/RPMS/noarch/rhel5client-2.0-1.noarch.rpm 
/bin/sh  
config(rhel5client) = 2.0-1
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(FileDigests) <= 4.6.0-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
yum  
rpmlib(PayloadIsXz) <= 5.2-1

And, as expected, the package won't install on RHEL 5:

# rpm -ihv --test /tmp/rhel5client-2.0-1.noarch.rpm 
error: Failed dependencies:
	rpmlib(FileDigests) <= 4.6.0-1 is needed by rhel5client-2.0-1.noarch
	rpmlib(PayloadIsXz) <= 5.2-1 is needed by rhel5client-2.0-1.noarch

Just to be clear: with RHUI 3 on both RHEL 6 and 7.

The fix we ended up going with was to set the following macros in the template spec file at /etc/rhui/templates/rh-client-config.spec for the client rpm that gets built

%global _binary_payload    w9.gzdio
%global _binary_filedigest_algorithm   1

This allows the rpm that is built to be built in a way that can be installed on RHEL5-RHEL7

Confirmed. Here's what the custom rpm requires now:

# rpm -qpR /tmp/rhui-5-1.noarch.rpm 
/bin/sh  
config(rhui) = 5-1
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
yum  

It can be installed on RHEL 5:

# rpm -ihv /tmp/rhui-5-1.noarch.rpm
Preparing...                ########################################### [100%]
   1:rhui                   ########################################### [100%]
enabled = 0

(The "enabled = 0" thing in the output is already tracked in a separate bug.)

And the configuration (using RHEL HA for RHEL 5 in the cert) works:

# yum repolist enabled
Loaded plugins: fastestmirror, security
Determining fastest mirrors
rhui-rhel-ha-for-rhel-5-server-rhui-rpms                 | 2.0 kB     00:00     
rhui-rhel-ha-for-rhel-5-server-rhui-rpms/primary         |  37 kB     00:00     
rhui-rhel-ha-for-rhel-5-server-rhui-rpms                                223/223
repo id                                  repo name                        status
rhui-rhel-ha-for-rhel-5-server-rhui-rpms Red Hat Enterprise Linux High Av 223
repolist: 223

Everything is also fine with a config RPM built on RHEL 6. Also, a config RPM built with the extra flags can be installed on RHEL 6 and 7. Marking as VERIFIED.
