From 07e9144aab08e26a61016c76eb7afb1f9dbec7e4 Mon Sep 17 00:00:00 2001 From: Jeremy Allison Date: Tue, 9 Feb 2010 15:23:38 -0800 Subject: Fix bug #7122 - Reading a large browselist fails (server returns invalid values in subsequent SMBtrans replies) There are two problems: 1). The server is off-by-one in the end of buffer space test. 2). The server returns 0 in the totaldata (smb_vwv1) and totalparams (smb_vwv0) fields in the second and subsequent SMBtrans replies. This patch fixes both. Jeremy.
