Scheduled kernel upgrade on EL12 Node.

This is to notify that we are going to perform kernel upgrade on one of our node having semi-dedicated servers hosted. We are going to install new “2.6.9-023stab048.4-smp” Virtuozzo kernel on it. There is a bug in current Virtuozzo kernel with dcache leaks which will be fixed with this new Virtuozzo kernel.

This will affect only one node having semi-dedicated servers hosted. This event will be carried out on 27th July 2008 (Sunday) at 2AM GMT. It will take 15-20 minutes approximately.

We will send email notification to customers hosted on this node.

Kernel upgrade was done smoothly. It took hardly 5 minutes for the whole process.

The new Virtuozzo 3.0 kernel provides security updates, driver updates, and some other important fixes..

The update includes fixes for the following issues:

• The handling of IEEE 802.11 frames was affecting several wireless LAN modules.
• A memory leak was found in the Red Hat Content Accelerator kernel patch.
• A flaw was found in the virtual filesystem (VFS). A local unprivileged
  user could truncate directories to which they had write permission.
• A flaw was found in the implementation of ptrace.
• A flaw was found in the way the Red Hat Enterprise Linux 4 kernel handled
  page faults when a CPU used the NUMA method for accessing memory on Itanium
  architectures.
• A possible NULL pointer dereference was found in the chrp_show_cpuinfo
  function when using the PowerPC architecture.
