RHBA-2011:1397 - Bug Fix Advisory

Topic

An updated nfs-utils package that fixes one bug is now available for Red Hat
Enterprise Linux 6.

Description

The nfs-utils package provides a daemon for the kernel Network File System (NFS)
server and related tools, which provides better performance than the traditional
Linux NFS server used by most users. This package also contains the mount.nfs,
umount.nfs, and showmount programs.

This update fixes the following bug:

• Previously, the function responsible for parsing the /proc/mounts file was not

able to handle single quote characters in the path name of a mount points
entries. As a consequence, an NFS exported file system could not be unmounted if
its mount point contained space characters. To fix this problem, the parsing
routine has been rewritten so that it now parses entries in the /proc/mounts
file properly. All NFS file systems now can be unmounted as expected.
(BZ#731309)

All users of nfs-utils are advised to upgrade to this updated package, which
fixes this bug.
