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.

1.Configure an iSCSI target
cat /etc/tgt/targets.conf
default-driver iser
<target iqn.2009-10.com.redhat:storage-1>
    write-cache off
    allow-in-use yes
    <backing-store /var/lib/tgtd/loop-disk-1-1>
        scsi_sn 6976011
        scsi_id 6976011
        lun 1
        bs-type rdwr
        device-type disk
    </backing-store>
</target>

service tgtd start

2.On Initiator discover target using iser interface.
iscsiadm -m discovery -I iser -p 192.168.0.4 -t st
Starting iscsid: [  OK  ]
[  OK  ]
192.168.0.4:3260,1 iqn.2009-10.com.redhat:storage-1

3.Try to login to session
iscsiadm -m node -l
iscsiadm: Could not login to [iface: iser, target: iqn.2009-10.com.redhat:storage-1, portal: 192.168.0.4,3260].
iscsiadm: initiator reported error (8 - connection timed out)
iscsiadm: Could not log into all portals
Comment 2 Milos Malik 2013-10-22 07:46:08 UTC 
Hi Bruno, are there other AVCs when you run the reproducer in permissive mode?
Comment 3 Bruno Goncalves 2013-10-22 12:19:20 UTC 
With selinux in permissive, it seems to have the same message, but it allows session login.
