RHBA-2009:0107 - Bug Fix Advisory

Topic

An updated nfs-utils package that fixes several bugs and adds various
enhancements is now available.

Description

The nfs-utils package provides both server and client system daemons as
well other related tools for the Network File System (NFS).

This updated nfs-utils package provides fixes for the following bugs:

• nfsstat no longer displays statistics about "versions of NFS that have

non-zero counts".

• kernel callbacks now work correctly when the '-n' command line switch is

used with rpc.stated.

• the command "netstat -s" no longer improperly shows negative numbers in

its output.

• rpc.gssd now uses file ownership to determine security credentials.
• command line arguments are now properly passed to rpc.nfsd by the NFS

init script.

• backgrounded NFS mounts now function as expected.
• the command "nfsstat -s" displayed negative values in its output after

the nfsd ran for a long time continuously with many clients performing
operations due to a signed integer overflow error.

• this updated package fixes a typo in the argument process of the

"--mounted" flag of the nfsstat command.

In addition, this updated package provides the following enhancements:

• the maximum number of simultaneous secure NFS mounts has been increased.
• the nfs-utils init scripts have been fixed so that they are now compliant

with Linux Standard Base (LSB) guidelines.

Also note that FS-Cache has been removed from Red Hat Enterprise Linux
5.3. Red Hat is now focusing its implementation on upstream efforts and,
once successful upstream integration has been achieved, we will review the
design for inclusion in a future Red Hat Enterprise Linux release based on
invasiveness and compatibility assessments.

Due to these developments in regard to FS-Cache, Red Hat does not encourage
the use of the Technology Preview in Red Hat Enterprise Linux 5.2. Red Hat
will be focusing on further refining this feature as per upstream
specifications.

Users are advised to upgrade to this updated nfs-utils package, which
resolves these issues and adds these enhancements.
