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.

# The CONFIG_RHN commands are required for reconfiguration of a

# of the RHN Satellite.
apache 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. Cliff. Reassigning to myself as the bugzillas are not tracked against the SELinux feature. The previous comment should have been "are *now*".

Description of problem: The default installation of Satellite 5.3.0 adds /usr/bin/rhn-generate-pem.pl to alias INSTALL_RHN in /etc/sudoers. I've grepped Spacewalk source and rhn-generate-pem.pl appears to be called in two places -- in spacewalk/setup/bin/spacewalk-setup, and in web/modules/rhn/RHN/SatInstall.pm. That spacewalk-setup is being used by root, so no sudo is needed (and called) there. That RHN::SatInstall calls sub generate_server_pem { my $class = shift; my %params = validate(@_, { ssl_dir => 1, system => 1, out_file => 0 }); my @opts; push @opts, '--ssl-dir=' . File::Spec->catfile($params{ssl_dir}, $params{system}); if ($params{out_file}) { push @opts, '--out-file=' . $params{out_file}; } my $opts = join(' ', @opts); my $content; open(FH, "/usr/bin/sudo /usr/bin/rhn-generate-pem.pl $opts |") or throw "(satinstall:generate_pem_error) Could not generate server.pem file: $OS_ERROR"; my @content = <FH>; close(FH); if (not $params{out_file}) { $content = join('', @content); } return $content; } But the function generate_server_pem is not used in the whole Spacewalk codebase except that bin/spacewalk-setup, and that script defines its own function. Therefore I assume it is dead code which can be removed, and so can /usr/bin/rhn-generate-pem.pl 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): Satellite-5.3.0-RHEL5-re20090206.1 How reproducible: Deterministic. Steps to Reproduce: 1. Install Satellite 5.3.0. 2. Look into /etc/sudoers. Actual results: /usr/bin/rhn-generate-pem.pl is there. Expected results: /usr/bin/rhn-generate-pem.pl is not there and Satellite continues to work OK. Additional info: This bug was modeled based on bug 484701.
