We always zero the invalidated PTE/PDE for superpage, which means that L1TF CPU vulnerability (CVE-2018-3620) can be only used for reading from the page at zero. Note that both i386 and amd64 exclude the page from phys_avail[] array, so this change is redundant, but I think that phys_avail[] on UEFI-boot does not need to do that. Eventually the blacklisting should be made conditional on CPUs which report that they are not vulnerable to L1TF. Reviewed by: emaste. jhb Sponsored by: The FreeBSD Foundation |
