RHBA-2005:626 - Bug Fix Advisory

Topic

Updated util-linux and mount packages that fix several bugs are now
available.

Description

The util-linux package contains a collection of basic system utilities.
The mount package contains a utility that makes a file system available for
use.

This update adds the following features to the mount command:

• support for systems where the same partition is shared between different

devices (e.g. multipath kernel drivers)

• support for OCFS and OCFS2 file systems

This update also fixes the following bugs:

• An issue with the group password in the newgrp command
• A hang on FSC P250 in the hwclock command
• An incomplete man page for the umount command
• An incorrect label in the ipcs command output
• Incorrect information in the fstab man page
• The /etc/shadow and /etc/gshadow permissions after the vipw command usage
• A buffer overflow in the sfdisk command
• An exit if the NFS server drops the request for the mount command with

the "fg" option

• A default TCP retransmit timeout on NFS mounts
• The mount command and am-utils use different mtab locking

All users of util-linux and mount should upgrade to these updated packages,
which resolve these issues.
