Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

Not an SELinux issue, these are leaked file descriptors from  	
hypervkvpd

Comment 7 Miroslav Grepl 2013-08-21 13:46:23 UTC
We added patches to Fedora to see how it works.

Comment 9 Lukas Vrabec 2014-04-18 09:03:08 UTC
I sent patch to Miroslav with hypervkvpd policy.

Comment 10 Miroslav Grepl 2014-04-18 09:18:53 UTC
Needs to be re-tested by hyperv folks.

Comment 13 Lukas Vrabec 2014-07-04 09:11:34 UTC
Could you re-test it also in permissive mode?  

Thank you!

Comment 14 Milos Malik 2014-07-04 09:32:04 UTC
The same AVCs appeared in permissive mode.

Comment 15 Lukas Vrabec 2014-07-04 10:01:12 UTC
Thank you, 

patch sent.
