+Subject: IPoIB: Fix world-writable child interface control sysfs attributes
+
+From: Or Gerlitz <ogerlitz@voltaire.com>
+
+commit 7a52b34b07122ff5f45258d47f260f8a525518f0 upstream.
+
+Sumeet Lahorani <sumeet.lahorani@oracle.com> reported that the IPoIB
+child entries are world-writable; however we don't want ordinary users
+to be able to create and destroy child interfaces, so fix them to be
+writable only by root.
