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.

Doc Type: Bug Fix
Doc Text:
SELinux policy for Red Hat Gluster Storage has been added Previously, SELinux policy for Red Hat Gluster Storage (RHGS) components was missing, and Gluster worked correctly only when SELinux was in permissive mode. With this update, SELinux policy rules for the *glusterd* (glusterFS Management Service), *glusterfsd* (NFS sever), *smbd*, *nfsd*, *rpcd*, adn *ctdbd* processes have been updated providing SELinux support for Gluster.

Comment 1 Milos Malik 2015-02-12 11:10:14 UTC 
What is the full path to S31ganesha-set.sh and S30samba-set.sh files? Which package do they come from?

Please provide the selinux-policy-targeted version too.
Comment 2 Milos Malik 2015-02-12 11:12:17 UTC 
Are there other SELinux denials on your machine?

Comment 5 Milos Malik 2015-02-12 12:41:56 UTC 
Could you re-run your scenario in permissive mode and attach those AVCs too?

# setenforce 0
# your scenario
# setenforce 1

Comment 8 Miroslav Grepl 2015-04-09 09:47:41 UTC 
Could you try to label them as bin_t and re-test it?

#chcon -t bin_t /var/lib/glusterd/hooks/1/set/post/S30samba-set.sh
#chcon -t bin_t /var/lib/glusterd/hooks/1/set/post/S31ganesha-set.sh

Comment 10 Sandro Bonazzola 2015-04-24 12:41:38 UTC 
Miroslav, it works better if you set a needinfo on me :-)
I'll try again applying your changes in comment #8.

In the meanwhile, can you take a look at attachment in comment #9 ?
It's a fresh output from ausearch -m avc from today on the same kind of deployment I was trying when I opened this bug.

I'd also suggest this for inclusion in 7.1.z.
Comment 11 Milos Malik 2015-04-24 12:53:56 UTC 
Based on AVCs in the last attachment:
 * glusterd wants to access /dev/random
 * glusterd wants to execute various shell scripts under /var/lib/glusterd/hooks
 * dhclient wants to access /run/dhclient-ovirtmgmt.pid file
 * sanlock wants to access a symbolic link somewhere under /run/libvirt/

above commands solve the issue reported in comment #0

Do you need another BZ for the denials in comment #9?
