Synopsis:          Updated kernel packages correct TLB flush problem.
Advisory ID:       RHBA-2003:144-01
Issue date:        2003-05-21
Updated on:        2003-05-21
Product:           Red Hat Linux

1. Topic:

Updated kernel packages correct a TLB (Translation Lookaside Buffer) flush

2. Relevant releases/architectures:

Red Hat Linux 7.2 - s390

3. Problem description:

The Linux kernel handles the basic functions of the operating system.

A flaw has been discovered in the kernel code handling translation
lookaside buffer flushing.  The flaw made it possible for a multithreaded
process (with threads running on more than one processor) to fail to note
that the TLB should be flushed for every processor on which the process's
threads had run.

The upgraded kernel packages contained in this erratum corrects the problem.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which are
not installed but included in the list will not be updated.  Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network.  Many
people find this an easier way to apply updates.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:


This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

5. RPMs required:
