Installation guide

32-bit process is now fixed.
cpuspeed has been updated to version 1.2.1-5. With this update, the cpuspeed init script now
loads the speedstep-centrino module if all other module loads fail. In addition, a user-space bug
that prevented the Powernow-k8 module from loading is now fixed.
The frysk suite of tools have been removed completely from this distribution. frysk was originally
introduced as a technology preview in Red Hat Enterprise Linux 5.0.
Previously, the partition I/O statistics provided by the iostat -x command were incomplete. In this
update, partition statistics are now calculated in the same manner as disk statistics, providing
coherent and comprehensive I/O statistics at the partition level.
A password disclosure flaw was found with configuration file for the Dovecot mail server. If a system
had the ssl_key_password option defined, any local user could view the SSL key password. (CVE-
2008-4870)
Note
This flaw did not allow the attacker to acquire the contents of the SSL key. T he password has
no value without the key file which arbitrary users should not have read access to.
To better protect even this value, however, the dovecot.conf file now supports the "!include_try"
directive. The ssl_key_password option should be moved from dovecot.conf to a new file
owned by, and only readable and writable by, root (ie 0600). T his file should be referenced from
dovecot.conf by setting the !include_try /path/to/password/file option.
8.2. x86_64 Architectures
ksh has been re-based to version 2008-02-02. This update adds multi-byte character handling,
addresses many job control problems and applies several bug fixes from upstream. Note that this
update to ksh preserves compatibility for existing scripts.
8.3. s390x Architectures
A vm convert bug prevented it from working properly on the vmur device node (/dev/0.0.000c).
This caused vm convert to fail when attempting to access dumps on the vmur device with the error
vmconvert: Open dump file failed! (Perm ission denied). An update to s390utils
in this release fixes this issue.
The init script and config file for the m on_procd daemon and m on_fsstatd daemon were
missing from the s390utils package. Consequently these daemons could not be built and used.
The missing files have been added in this update which resolves this issue.
8.4. PowerPC Architectures
A bug that prevented the ehci_hcd module from reloading on this architecture is now fixed. This
ensures that the Belkin 4-port PCI-Express USB Lily adapter (and other similar devices) now function
properly with Red Hat Enterprise Linux 5 when they use the ehci_hcd module.
The libhugetlbfs library is now re-based to version 1.3. This update applies several upstream
improvements to the library, thereby improving the performance of applications that use Huge pages.
