Bug Description

fs/namespace.c in the Linux kernel through 3.16.1 does not properly restrict clearing MNT_NODEV, MNT_NOSUID, and MNT_NOEXEC and changing MNT_ATIME_MASK during a remount of a bind mount, which allows local users to gain privileges, interfere with backups and auditing on systems that had atime enabled, or cause a denial of service (excessive filesystem updating) on systems that had atime disabled via a "mount -o remount" command within a user namespace.

Break-Fix: 0c55cfc4166d9a0f38de779bd4d75a90afbe7734 9566d6742852c527bf5af38af5cbb878dad75705
Break-Fix: 0c55cfc4166d9a0f38de779bd4d75a90afbe7734 ffbc6f0ead47fa5a1dc9642b0331cb75c20a640e
