[Impact]
Paging structure caches are not always flushed as part of a TLB shootdown operation on x86.
[Test Case]
Ideally, we'd be able to use the test case described in the Project Zero bug report. However, it depends on certain processor features as well as custom kernel changes to make the proof-of-concept more likely to be successful.
Instead, I think we're limited to simple boot testing and then will need to rely on our regular SRU testing.
[Regression Potential]
Considerable since the changes are in mm/ but these three patches have been released in the upstream linux-stable trees for a while now. |
