Red Hat Bugzilla – Bug 1297184
Mounting with "-o noatime" or "-o noexec" causes "nosuid,nodev" to be set as well

+++ Use this bug to backport the fix to release-3.6 +++
Description of problem:
With additional tests after fixing bug 1296992 I noticed that mounting with "-o noatime" or "-o noexec" the additional "nosuid,nodev" mount options are set as well.
Mounting without any options does not add "nosuid,nodev"
Version-Release number of selected component (if applicable):
mainline and branches with backport of bug 1296992
Steps to Reproduce:
1. mount a Gluster volume with "-o noatime" or "-o noexec"
2. compare mount options in /proc/mounts
The "nosuid,nodev" mount options are automatically added, even when not specified in the mount command.
Mounting with additional options should only add/change those options, not automatically add others.
This most likely is caused by the flag handling in do_mount() in contrib/fuse-util/fusermount.c. Needs some investigation on the reasoning behind this.

Oop, bug 1294809 is the one that makes it possible again to mount with "-o noatime" and the like.
This bug is being closed as GlusterFS-3.6 is nearing its End-Of-Life and only important security bugs will be fixed. This bug has been fixed in more recent GlusterFS releases. If you still face this bug with the newer GlusterFS versions, please open a new bug.
