Tyler Hicks 2aac0cf886 eCryptfs: NULL crypt_stat dereference during lookup ... If ecryptfs_encrypted_view or ecryptfs_xattr_metadata were being specified as mount options, a NULL pointer dereference of crypt_stat was possible during lookup. This patch moves the crypt_stat assignment into ecryptfs_lookup_and_interpose_lower(), ensuring that crypt_stat will not be NULL before we attempt to dereference it. Thanks to Dan Carpenter and his static analysis tool, smatch, for finding this bug.
