Red Hat Bugzilla – Bug 484718
/usr/sbin/rhnreg_ks not needed in /etc/sudoers
Last modified: 2009-09-10 15:12:03 EDT
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):
Steps to Reproduce:
1. Install Satellite 5.3.0.
2. Look into /etc/sudoers.
/usr/sbin/rhnreg_ks is there.
/usr/sbin/rhnreg_ks is not there and Satellite continues to work OK.
This bug was modeled based on bug 484717.
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
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.
The previous comment should have been "are *now*".
Committed to Spacewalk repo, 43b2f8b4ae8ff06269e540a9a73287f0b731fd63.
With compose Satellite-5.3.0-RHEL5-re20090220.1 available, moving ON_QA.
[root@grandprix ~]# cat /etc/sudoers | grep /usr/sbin/rhnreg_ks
[root@xen5 ~]# grep rhnreg_ks /etc/sudoers
satellite works good.
verified in stage on xen5
