Chapter 1. Package Updates
178
• in some situations the NFS server incorrectly refused mounts to hosts that had a host alias in a NIS
netgroup. (
BZ#478952
1270
)
• in some situations the NFS client used its cache, rather than using the latest version of a file or
directory from a given export. This update adds a new mount option, "lookupcache=", which allows
the NFS client to control how it caches files and directories. Note: The Red Hat Enterprise Linux
5.4 kernel update (the fourth regular update) must be installed in order to use the "lookupcache="
option. Also, "lookupcache=" is currently only available for NFS version 3. Support for NFS version 4
may be introduced in future Red Hat Enterprise Linux 5 updates. Refer to Red Hat Bugzilla #511312
for further information. (

Users of nfs-utils should upgrade to this updated package, which contains backported patches to
correct these issues. After installing this update, the nfs service will be restarted automatically.
1.154. nfs-utils-lib
1.154.1. RHBA-2009:1250: bug fix update
Updated nfs-utils-lib packages that fix a bug are now available.
The nfs-utils-lib package contains support libraries required by programs in the nfs-utils package.
These updated packages apply a fix for the following bug:
• when resolving a group ID, a group's data structure is stored in a buffer. When the buffer size was
exceeded, the default no-group value was used in place of the group ID, removing certain user
privileges. Larger buffer spaces are now provided when the defined buffer is exceeded, so groups
are mapped to the appropriate ID. (
BZ#453804
1272
)
Users are advised to upgrade to these updated packages, which resolve this issue.
1.155. nfs4-acl-tools
1.155.1. RHEA-2009:1407: enhancement update
Updated nfs4-acl-tools packages that fix a bug are now available.
The nfs4-acl-tools packages provide utilities for managing NFSv4 Access Control Lists (ACLs) on
files and directories mounted on ACL-enabled NFSv4 file systems. These updated packages fix the
following bug:
• the mapping between ACLs in the draft POSIX standard and NFSv4 ACLs used in previous versions
of the nfs4-acl-tools did not accept all NFSv4 ACLs. As a result, attempts to set an ACL on an NFS
server could fail with the message "Operation not supported". Nfs4-acl-tools has been rebased to
upstream version 0.3.3, which contains completely new mapping code that handles practically all
NFSv4 ACLs. (
BZ#507443

All NFS users are advised to upgrade to these updated packages, which resolve this issue.
