RHBA-2010:0604 - Bug Fix Advisory

Topic

An updated nfs-utils package that fixes a bug that presented in some
circumstances when NFS file system mounts were attempted in the background
is now available.

Description

The nfs-utils package provides a daemon for the kernel Network File System
(NFS) server, and related tools such as the mount.nfs, umount.nfs, and
showmount programs.

This updated package fixes the following bug:

• when an Network File System (NFS) client attempts to mount an NFS

exported file system the try_mount() function is called once and two
variables -- mount_opts and extra_opts -- are setup to handle any options
sent with the mount command. One option -- bg -- sets the command to fork
and continue attempting to mount the file system in the background should
the initial attempt fail. In some circumstances, when the bg option was
used and the initial call to try_mount() failed, options set in the
extra_opts variable were lost when the try_mount() function was called
again. This update fixes this: using the bg option now works as expected,
with all specified and default options honored when an NFS export is
mounted in the background. (BZ#614491)

All nfs-utils users should upgrade to this updated package, which resolves
this issue.
