Windows/L1TF: SMT reported vulnerable when no SMT is present

[matsimon]

Hi

Using the Windows binary on Windows 7 with an Intel Core i5-4570 (4 cores, no SMT) in the L1TF section SMT is being reported as vulnerable. Yet in the section about MDS SMT is reported as Unaffected. - The first look result looks erroneous to me - correct?

It looks like it boils down to:

ridl/source/msw/l1tf.c

Line 42 in 508d549

info->smt_vuln = 1; /* TODO: how do we know? */

Also commit 2e13baf added the use of the function check_smt() for l1tf.c on Linux and macOS but not Windows.

Is check_smt() not available for Windows (yet) or was it forgotten to be added in the process?

Regards
Mathieu

Thanks, seems I forgot to implement that. It's been fixed in 7e4fc98. I will rebuild the binaries for Microsoft Windows soon.

Thanks for the update, I'll give a test-drive ony my machine, likely by the end of the week if I see new binaries and give feedback.
