Analyze performance impact of Spectre and Meltdown patches

15 Febbraio 2018
Comments off

Reading Time: 6 minutesThe 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)?

Meltdown and Spectre: far from the solution?

12 Febbraio 2018
Comments off

Reading Time: 8 minutesIn 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 […]

Reading Time: 5 minutesLinux Kernel 4.15 è stato rilasciato il 28 gennaio 2018, dopo un lungo ciclo di sviluppo, tanto da arrivare alla RC9, cosa che non succedeva dal 2011. Questa versione è la prima che contiene specifiche ottimizzazioni e soluzioni specifiche per Meltdown e Spectre issues (benché anche alcuni kernel precedenti avessero alcune protezioni). Notare che in realtà i problemi sono tre problemi distinti: Meltdown è uno, ma poi ci sono due varianti di Spectre (note come v1 e v2). Il Kernel 4.15 al momento manca ancora mancano ancora dei fix per ARM e per la variante 1 […]
