[PATCH v2 0/2] KVM: TDX: INIT_MEM_REGION fixes

From: Sean Christopherson

Date: Thu Aug 06 2026 - 13:22:18 EST


I completely lost track of this, meant to post these patches weeks ago.
Compile tested only.

v2:
- Fix an off-by-one bug.
- Use gpa_t instead of raw u64.
- Tweak the order of checks to bundle similar checks together, and to perform
the super basic checks (alignment, size, etc.) first.

v1: https://lore.kernel.org/all/ak0skG064rhKUC8d@xxxxxxxxxx

Haotian Jiang (1):
KVM: TDX: Reject INIT_MEM_REGION if number of bytes would overflow a
u64

Sean Christopherson (1):
KVM: TDX: Fix a benign off-by-one bug on the end GPA for
INIT_MEM_REGION
