Description Jan Pazdziora 2009-02-09 11:43:05 EST
Description of problem:

The default installation of Satellite 5.3.0 adds /usr/sbin/rhnreg_ks to alias INSTALL_RHN in /etc/sudoers.

I've grepped Spacewalk source and /usr/sbin/rhnreg_ks appears to be called only in satellite/install/install.pl and spacewalk/certs-tools/rhn_bootstrap_strings.py. In neither of those cases it is invoked via sudo.

Therefore I assume /usr/sbin/rhnreg_ks can be removed from /etc/sudoers.

Note: I did this scan through our code to figure out if there are some commands that need additional SELinux treatment.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Install Satellite 5.3.0.
2. Look into /etc/sudoers.
Actual results:

/usr/sbin/rhnreg_ks is there.

Expected results:

/usr/sbin/rhnreg_ks is not there and Satellite continues to work OK.

Additional info:

This bug was modeled based on bug 484717.
Comment 1 Jan Pazdziora 2009-02-10 07:25:29 EST
The proposed change is to remove the INSTALL_RHN section and merge whatever needs to be there to CONFIG_RHN. The proposed sudoers.rhn is below. I've tested that with this, the Satellite/Spacewalk works and runs external commands fine.

## RHN specifics ##
Cmnd_Alias CONFIG_RHN = /usr/sbin/rhn-sat-restart-silent,\
                        /etc/rc.d/np.d/step Monitoring install,\
                        /etc/rc.d/np.d/step MonitoringScout install,\
                        /etc/rc.d/np.d/step Monitoring uninstall,\
                        /etc/rc.d/np.d/step MonitoringScout uninstall,\
                        /sbin/service Monitoring restart,\
                        /sbin/service MonitoringScout restart,\
                        /sbin/service taskomatic restart

# The CONFIG_RHN commands are required for reconfiguration of a
# running RHN Satellite.  They should be enabled for proper operation
# of the RHN Satellite.
apache  ALL=(root)      NOPASSWD: CONFIG_RHN
tomcat  ALL=(root)      NOPASSWD: CONFIG_RHN

# These two directives allow tomcat and apache to invoke CONFIG_RHN
# commands via sudo even without a real tty
Defaults:tomcat !requiretty
Defaults:apache !requiretty

This is a throw back from the old Installer - where we had command line install laid down packages. The WebUI then went through configuration/installation of Satellite to get it running, with many many steps, unlike the new WebUI portion that just asks for Username/password to be created for Sat Admin account.

Reassigning to myself as the bugzillas are not tracked against the SELinux feature.
Comment 4 Jan Pazdziora 2009-02-11 02:28:10 EST
The previous comment should have been "are *now*".
Comment 5 Jan Pazdziora 2009-02-17 05:23:38 EST
Committed to Spacewalk repo, 43b2f8b4ae8ff06269e540a9a73287f0b731fd63.

satellite works good.

verified in stage on xen5
