Date: Fri, 4 Jul 2014 15:19:24 -0700 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Mateusz Guzik <mguzik@...hat.com>, linux-nfs@...r.kernel.org, Trond Myklebust <trond.myklebust@...marydata.com> Subject: [PATCH 3.14 35/59] NFS: populate ->net in mount data when remounting 3.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Mateusz Guzik <mguzik@...hat.com> commit a914722f333b3359d2f4f12919380a334176bb89 upstream. Otherwise the kernel oopses when remounting with IPv6 server because net is dereferenced in dev_get_by_name. Use net ns of current thread so that dev_get_by_name does not operate on foreign ns. Changing the address is prohibited anyway so this should not affect anything.
