Release Notes
38
• Because the
xterm
binary had the set group ID (
setgid
) bit configured, certain environmental
variables (such as
LD_LIBRARY_PATH
and
TMPDIR
) were unset. In this release, the
xterm
binary
now has mode
0755
permissions configured, which resolves this issue.
• The recommended method for balancing the load on NIS servers when multiple machines are
connecting with ypbind has changed with this release. The ypbind daemon's behavior has not
changed: it still pings all NIS servers listed in the
/etc/ypbind
configuration file and then binds to
the single fastest-responding server. Before, it was recommended to list all available NIS servers
in each machine's
/etc/ypbind.conf
configuration file. However, because even servers under
high load can respond quickly to this ping, thus inadvertently increasing their own load, it is now
recommended for administrators to list a smaller number of available NIS servers in each machine's
ypbind.conf, and to vary this list across machines. In this way, NIS servers are automatically load-
balanced due to not every NIS server being listed as being available to every machine.
•
OpenMotif
has been re-based to upstream version 2.3.1. This update applies several bug fixes,
including:
• A bug in the way
OpenMotif
handled the
Grab
and
Ungrab
events is now fixed. In previous
releases, this bug could cause the display to lock.
• A bug in
nedit
could cause it to crash when using the
nedit
graphical user interface. This
was caused by a function in the code that causes a segmentation fault in some cases of item
selection, which is now fixed.
•
dbus
has been re-based to version 1.1.2. This update fixes a bug wherein multi-threaded programs
could cause a deadlock in
dbus
. In previous releases, as one thread listened to
dbus
and
processed messages, the second thread would send messages to
dbus
.
•
strace
has been re-based to version 4.5.18. This fixes several bugs, including:
• A bug that caused
strace
to crash when the
-f
option was used on some multi-threaded
programs (particularly on 64-bit systems) is now fixed.
• A bug that prevented the 64-bit version of
strace
from executing a
vfork()
function call on a 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)
