INSTALLING THE UPDATES
We recommend that all users of Ksplice Uptrack running UEKR5 4.14.35
on OL7 install these updates.
On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.
Alternatively, you can install these updates by running:
# /usr/sbin/uptrack-upgrade -y
* Denial-of-service and filesystem corruption during XFS writeback.
A race between certain XFS writeback operations can lead to system
crashes and filesystem corruption.
* Denial-of-service in VM during CPU hotplug operation.
A logic error when performing a CPU hotplug operation on a running
virtual machine can cause an internal error in KVM, resulting in a
denial-of-service to the virtual machine.
* Timestamp counter clocksource is disabled unexpectedly during CPU hotplug.
Under certain conditions, a CPU hotplug operation on a virtual machine
can cause the TSC clocksource to be incorrectly marked as unstable.
Ksplice support is available at ksplice-support_ww at oracle.com.
