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 Text:
Previously, with SELinux in enforcing mode, it was not possible to create a UNIX Domain Socket on a Red Hat Gluster Storage (RHGS) volume. As a consequence, the user could not store containers on an RHGS volume. The relevant policy module has been updated, and the user is now able to store containers on a Gluster volume.

Description Shashank Raj 2016-04-28 19:39:54 UTC 
+++ This bug was initially created as a clone of Bug #1331559 +++

Description of problem:

Cases in pynfs test suite fails because of selinux errors.

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

nfs-ganesha-2.3.1-4

selinux-policy-3.13.1-60.el7_2.3.noarch
selinux-policy-targeted-3.13.1-60.el7_2.3.noarch
selinux-policy-devel-3.13.1-60.el7_2.3.noarch

How reproducible:

Always

Steps to Reproduce:

1. Configure nfs-ganesha on a 4 node cluster.
2. Create a dist-rep volume and enable ganesha on it
3. From the client start executing pynfs test suite on the volume

Observe that some of the cases fails and some of them are skipped 

LOOKSOCK st_lookup.testSocket                                     : FAILURE
           LOOKUP of /testvolume/tree/socket should return
           NFS4_OK, instead got NFS4ERR_NOENT

MKSOCK   st_create.testSocket                                     : FAILURE
           CREATE in empty dir should return NFS4_OK, instead got
           NFS4ERR_ACCESS


ACC1s    st_access.testReadSocket                                 : OMIT
           Dependency LOOKSOCK st_lookup.testSocket had status
           FAILURE.


RM1s     st_remove.testSocket                                     : OMIT
           Dependency MKSOCK st_create.testSocket had status
           FAILURE.

4. Observe in /var/log/audit/audit.log, below AVC's are seen which are the cause for the failure of cases in pynfs test suite

Actual results:

Cases in pynfs test suite fails because of selinux errors.

Expected results:

No denial AVC's should be seen and it should not effect any functionality

Additional info:
Comment 3 Shashank Raj 2016-05-05 10:21:32 UTC 
The given local policy works fine; no denial AVC's are seen in audit.log and all the corresponding cases passed without any issues
