From 1b244081af462c223cfa6a1ae881a902af64c306 Mon Sep 17 00:00:00 2001 From: Steve French Date: Thu, 11 Jul 2013 19:17:40 -0500 Subject: Do not attempt to do cifs operations reading symlinks with SMB2 When use of symlinks is enabled (mounting with mfsymlinks option) to non-Samba servers, we always tried to use cifs, even when we were mounted with SMB2 or SMB3, which causes the server to drop the network connection. This patch separates out the protocol specific operations for cifs from the code which recognizes symlinks, and fixes the problem where with SMB2 mounts we attempt cifs operations to open and read symlinks. The next patch will add support for SMB2 for opening and reading symlinks. Additional followon patches will address the similar problem creating symlinks.
