Updated udisks packages that fix one bug and add two enhancements are now available for Red Hat Enterprise Linux 6.
The udisks packages provide a daemon, D-Bus API, and command-line tools for managing disks and storage devices.
- Prior to this update, an external storage device could be unmounted forcefully when a device entered the DM_SUSPENDED=1 state for a moment while performing a set of changes during the cleanup procedure. To fix this bug, an exception for ignoring such a device in the cleanup procedure has been added to the UDisks daemon. As a result, DeviceMapper devices are no longer unmounted forcefully in the described situation.
- With this update, additional mount points and a list of allowed mount options can be specified by means of udev rules. Flexibility of the udev rules format enables the system administrator to write custom rules to enforce or limit specific mount options for a specific set of devices. For example, USB drives can be limited to be always mounted as read-only.
- This update enables the user to configure the udisks tool to enforce the "noexec" global option on all unprivileged users mount points. On desktop systems, the "noexec" option can protect users from mistakenly running certain applications.
Users of udisks are advised to upgrade to these updated packages, which fix this bug and add these enhancements.
