Jeffrey Mitchell 6b902a1e00 ecryptfs: fix kernel panic with null dev_name ... commit 9046625511 upstream. When mounting eCryptfs, a null "dev_name" argument to ecryptfs_mount() causes a kernel panic if the parsed options are valid. The easiest way to reproduce this is to call mount() from userspace with an existing eCryptfs mount's options and a "source" argument of 0. Error out if "dev_name" is null in ecryptfs_mount() Fixes: 237fead619 ("[PATCH] ecryptfs: fs/Makefile and fs/Kconfig") Cc: stable@vger.kernel.org Signed-off-by: Jeffrey Mitchell <jeffrey.mitchell@starlab.io> Signed-off-by: Tyler Hicks <code@tyhicks.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2021-05-22 10:57:15 +02:00
