perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

All,

New web100 kernel packages are now available for users of the perfSONAR toolkit. You may run 'yum update' to grab the new kernel. You should restart your host after the upgrade completes. Full details on this particular patch can be found in the previous email.

Note this is just a kernel upgrade and the other perfSONAR packages have NOT been updated. Please let us know if you have any questions or issues.

Thank you,

The perfSONAR Team

All;

The past few days have marked the release of a couple new Red Hat CVEs:

A 'yum update' may give you a new non-web100 kernel and therefore break access to NDT/NPAD. Consult our FAQ for more info: http://www.perfsonar.net/about/faq/#Q25

Our read of the CVEs does not find any issue of concern specific to the toolkit. Its possible the host may be vulnerable to some types of DoS attacks in some particular cases. If you are in doubt about your kernel, feel free to review the CVE,  upgrade to the latest version, and forgo NDT/NPAD support for the time being.  We are in the process of building and testing a new kernel, and will alert you when we have our web100 patched version available. We'll try to have it ready as soon as possible.

Thank you for your patience,
