Analyze performance impact of Spectre and Meltdown patches

Reading Time: 6 minutes

The mitigations for Meltdown and Spectre issues have involved a combination of different type of fixes: some software based, such as Microsoft and Linux versions of the “kernel page table isolation” protection, but also fome hardware based, like the Intel’s microcode updates (part that is still missing in most cases).

Both type of patches can cause performance overheads and have some kind of impact on your environment. But how can you estimate it (before apply the patches) and how can you measure it (when the patches have been applied)?

When you add a Veeam proxy to the Veeam Backup infrastructure, in some cases you can have an error message like this: “Failed to create persistent connection to ADMIN$”

And the proxy is not added to the infrastructure.

There can be different reason, but the most common case occour when you have proxyes that are “workgroup only” and when you are using dedicated local accounts, and not the “Administrator” one. And you have Windows Server 2012 or later.

Meltdown and Spectre: far from the solution?

Reading Time: 8 minutes

In June 2017, a team constituted of independent researchers, university research labs, and some of Google’s Project Zero members and cyberus technology discovered two security vulnerabilities enabled by the widespread use of speculative execution in most of the CPU. The problem was also independently discovered by other researchers, at about the same time. These vulnerabilities, called Meltdown and Spectre, were made public in January 2018.

Meltdown and Spectre are critical vulnerabilities existing in several modern CPU: these hardware bugs allow programs to steal data which is currently processed on the computer. Meltdown and Spectre can affect personal computers, mobile devices, server and several cloud services.

Linux Kernel 4.15 has been released on 28 Jan 2018 and, thanks to the entire Linux Kernel development team, this release contains the latest code to deal with Meltdown and Spectre issues and minize the related risks.

The Kernel is the core code in the operating system managing low level tasks. In the update both vulnerabilities are explicitly addressed.And the interesting aspect is that the performance are not so bad!

There are infact three instinct vulnerabilities identified, one Meltdown and two variations of Spectre (known as v1 and v2). Kernel 4.15 actually address only Meltdown and Spectre v2 issues.
