An Oracle Linux 6 system with the oracle-ofed-release packages installed and an iSER (iSCSI Extensions for RDMA) target configured, fails to login to the iSER target as an initiator. On the Oracle Linux 6 initiator machine, the following behavior is typical:

# iscsiadm -m node -T iqn.iser-target.t1 -p 10.196.100.134 --login
Logging in to [iface: default, target: iqn.iser-target.t1, portal:
10.196.100.134,3260] (multiple)
iscsiadm: Could not login to [iface: default, target: iqn.iser-target.t1,
portal: 10.196.100.134,3260].
iscsiadm: initiator reported error (8 - connection timed out)
iscsiadm: Could not log into all portals

This is expected behavior resulting from an errata fix for CVE-2016-4564, to protect against a write from an invalid context.
