Subject: Memory Read Only Enforcement: VMM assisted kernel rootkit mitigation for KVM V4
Here is change log from V3 To V4:
- Fixing spelling/grammar mistakes suggested by Randy Dunlap
- Changing the hypercall interface to be able to process multiple pages
per one hypercall also suggested by Randy Dunlap. It turns out that
this will save lots of vmexist/memory slot flushes when protecting many
pages.
[PATCH RFC V4 1/3] KVM: X86: Memory ROE documentation
[PATCH RFC V4 2/3] KVM: X86: Adding arbitrary data pointer in kvm memslot iterator functions
[PATCH RFC V4 3/3] KVM: X86: Adding skeleton for Memory ROE
