Revision 6497d0a9c53df6e98b25e2b79f2295d7caa47b6e authored by Gustavo A. R. Silva on 31 July 2019, 17:54:28 UTC, committed by Doug Ledford on 01 August 2019, 16:14:15 UTC
sl is controlled by user-space, hence leading to a potential exploitation of the Spectre variant 1 vulnerability. Fix this by sanitizing sl before using it to index ibp->sl_to_sc. Notice that given that speculation windows are large, the policy is to kill the speculation on the first load and not worry if it can be completed with a dependent load/store [1].
