RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Orion Poplawski 2014-09-29 22:48:09 UTC
Description of problem:

In order to enable zabbix to monitor LVM thin pool usage, I needed to allow it to run lvs via sudo:

UserParameter=vfs.dev.lvm[*],/usr/bin/sudo -u root /sbin/lvs --noheadings -o $2 $1

This however was blocked by SELinux.  This seems to make it work:

module zabbix_sudo 1.0;

require {
        type sudo_exec_t;
        type zabbix_agent_t;
        class file { execute execute_no_trans };
}
#
##============= zabbix_agent_t ==============
allow zabbix_agent_t sudo_exec_t:file execute_no_trans;
allow zabbix_agent_t sudo_exec_t:file execute;

Perhaps a boolean similar to the zoneminder_run_sudo boolean could be added for this?

Version-Release number of selected component (if applicable):
selinux-policy-3.7.19-251.el6.noarch

The selinux-policy packages present in RHEL-6.6 fix the problem. Please see BZ#1081038.
