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 Alexander Kirillov 2012-07-26 11:22:04 UTC 
Description of problem:

munin_stats plugin no longer works after upgrade to 6.3

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

munin-node-1.4.7-5.el6.noarch
selinux-policy-targeted-3.7.19-155.el6_3.noarch

Additional info:

On a running system the problem could be fixed as follows:

1. Change the context of the plugin executable:

# semanage fcontext -a \
> -t munin_system_plugin_exec_t '/usr/share/munin/plugins/munin_.*'

Note:

Actually this should replace a meaningless rule for
'/usr/share/munin/plugins/munin_*' in the current targeted policy.

# restorecon -Rv /usr/share/munin

2. Add the following rules to a local policy:

type munin_system_plugin_t;
type munin_log_t;
type var_log_t;

allow munin_system_plugin_t var_log_t:dir search;
allow munin_system_plugin_t munin_log_t:dir search;
allow munin_system_plugin_t munin_log_t:file { read open };
Comment 1 d. johnson 2012-08-07 02:58:02 UTC 
This looks like it may be a policy issue in el6, moving to there for comment.
Comment 3 Miroslav Grepl 2012-08-07 14:32:24 UTC 
Yes, we need to backport it from Fedora.
Comment 4 Miroslav Grepl 2012-08-07 23:26:57 UTC 
Fixed in selinux-policy-3.7.19-159.el6
Comment 5 Michal Trunecka 2012-09-24 13:59:19 UTC 
Here is another AVC. I just let munin daemon run and I discovered this during some non-related tests:
selinux-policy-3.7.19-162.el6.noarch
munin-1.4.7-5.el6.noarch
munin-node-1.4.7-5.el6.noarch
munin-common-1.4.7-5.el6.noarch

Found 1 semantic av rules:

Comment 11 Michal Trunecka 2012-11-28 08:07:30 UTC 
And what about the rule from Comment 7?

 allow munin_system_plugin_t munin_log_t:dir search;
Comment 12 Miroslav Grepl 2012-11-28 08:31:48 UTC 
Should be also fixed.
