From e4aa25e7801163df058f62c617b859e9d3d4b148 Mon Sep 17 00:00:00 2001 From: Steve French Date: Mon, 1 Oct 2012 12:26:22 -0500 Subject: [CIFS] Fix SMB2 negotiation support to select only one dialect (based on vers=) Based on whether the user (on mount command) chooses: vers=3.0 (for smb3.0 support) vers=2.1 (for smb2.1 support) or (with subsequent patch, which will allow SMB2 support) vers=2.0 (for original smb2.02 dialect support) send only one dialect at a time during negotiate (we had been sending a list).
