From cd2dca60be6f4742b63373fd7e4b445c8a634e51 Mon Sep 17 00:00:00 2001 From: Paulo Alcantara Date: Wed, 13 Jun 2018 13:54:14 -0300 Subject: [PATCH] cifs: Fix encryption/signing Since the rfc1002 generation was moved down to __smb_send_rqst(), the transform header is now in rqst->rq_iov[0]. Correctly assign the transform header pointer in crypt_message().
