GUI indication and options for MDS mitigation
Added by Jim Pingle over 5 years ago.
Updated over 4 years ago.
Description
Similar to the option for Kernel PTI on system_advanced_misc.php we should have an option for MDS.
It is controlled by sysctl oid hw.mds_disable
:
0 - mitigation disabled
1 - VERW instruction (microcode) mitigation enabled
2 - Software sequence mitigation enabled (not recommended)
3 - Automatic VERW or Software selection
Also in the system info widget on the Dashboard, the value of hw.mds_disable_state
can be output to show the current state.
- Subject changed from GUI indication an options for MDS mitigation to GUI indication and options for MDS mitigation
- Status changed from New to In Progress
- Assignee set to Jim Pingle
- Status changed from In Progress to Feedback
- % Done changed from 0 to 100
Dashboard reflects chosen MDS settings. Looks good.
- Status changed from Feedback to Resolved
- Target version changed from 2.5.0 to 2.4.5
- Status changed from Resolved to Feedback
Needs checked and/or tested again on 2.4.5 snapshots
- Status changed from Feedback to Resolved
Works as expected. The mitigation can be enabled or disabled via system_advanced_misc.php and the status is correctly reflected in the System Information widget.
