Subject: [PATCH v3] kvm:vmx: more complete state update on APICv on/off
|
||||
Date: 2016-05-18 14:48:20 GMT (1 day, 21 hours and 23 minutes ago)
|
||||
|
||||
The function to update APICv on/off state (in particular, to deactivate
|
||||
it when enabling Hyper-V SynIC), used to be incomplete: it didn't adjust
|
||||
APICv-related fields among secondary processor-based VM-execution
|
||||
controls.
|
||||
|
||||
As a result, Windows 2012 guests would get stuck when SynIC-based
|
||||
auto-EOI interrupt intersected with e.g. an IPI in the guest.
|
||||
|
||||
In addition, the MSR intercept bitmap wasn't updated to correspond to
|
||||
whether "virtualize x2APIC mode" was enabled. This path used not to be
|
||||
triggered, since Windows didn't use x2APIC but rather their own
|
||||
synthetic APIC access MSRs; however it represented a security risk
|
||||
because the guest running in a SynIC-enabled VM could switch to x2APIC
|
||||
and thus obtain direct access to host APIC MSRs (thanks to Yang Zhang
|
||||
<yang.zhang.wz@gmail.com> for spotting this).
|
||||
|
||||
The patch fixes those omissions.

|
||||
v2 -> v3:
|
||||
- only switch to x2apic msr bitmap if virtualize x2apic mode is on in vmcs
|
||||
|
||||
v1 -> v2:
|
||||
- only update relevant bits in the secondary exec control
|
||||
- update msr intercept bitmap (also make x2apic msr bitmap always
|
||||
correspond to APICv)
