The kernel is moved ahead to version 3.10.0-693.21.1.el7 To summarize: CVE-2017-5753 [bounds check bypass] aka 'Spectre Variant 1' This is fixed by load fences and is "baked in" and cannot be turned off. CVE-2017-5715 [branch target injection] aka 'Spectre Variant 2' This is fixed by a combination of retpolines and IBPB, or IBRS+IBPB if on skylake. This requires a microcode change in the processors. This feature, if on, has a significant performance impact. It is assumed on unless turned off via the "nospectre_v2" bootarg. CVE-2017-5754 [rogue data cache load] aka 'Meltdown' aka 'Variant 3' This is fixed by page table isolation using the Kaiser patches. This feature is assumed on unless turned off via the "nopti" bootarg. As of the commit date, we have changed the installer kickstarts to issue both "nopti nospectre_v2" bootargs to minimize realtime impacts by default. The customer will be able to optionally sacrifice performance for extra security at datafill time.

Subject: [PATCH 12/33] PCI: Add ACS quirk for Intel Fortville NICs
|
|
|
|
Use quirks to determine isolation for now until a later kernel can
|
|
properly read the Fortville ACS capabilities.
