Subject: [PATCH v2 0/2] KVM: TDX: INIT_MEM_REGION fixes
Date: Thu, 6 Aug 2026 10:06:00 -0700 [thread overview]
Message-ID: <20260806170602.4112602-1-seanjc@google.com> (raw)
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@google.com

KVM: TDX: Reject INIT_MEM_REGION if number of bytes would overflow a
u64

KVM: TDX: Fix a benign off-by-one bug on the end GPA for
