Please pull a small series to clean up and harden kvm_set_memory_region(). KVM s390 is building on this branch/tag to create a KVM-internal memslot for its ucontrol stuff, hence the dedicated pull request (and I didn't have any other pending "generic" changes). https://lore.kernel.org/all/20250116113355.32184-1-imbrenda@xxxxxxxxxxxxx The following changes since commit 10b2c8a67c4b8ec15f9d07d177f63b563418e948: Merge tag 'kvm-x86-fixes-6.13-rcN' of https://github.com/kvm-x86/linux into HEAD (2024-12-22 12:59:33 -0500) are available in the Git repository at: https://github.com/kvm-x86/linux.git tags/kvm-memslots-6.14 for you to fetch changes up to 0cc3cb2151f9830274e7bef39a23dc1da1ecd34a: KVM: Disallow all flags for KVM-internal memslots (2025-01-14 17:36:16 -0800) ---------------------------------------------------------------- KVM kvm_set_memory_region() cleanups and hardening for 6.14: - Add proper lockdep assertions when setting memory regions. - Add a dedicated API for setting KVM-internal memory regions. - Explicitly disallow all flags for KVM-internal memory regions. ---------------------------------------------------------------- Sean Christopherson (5): KVM: Open code kvm_set_memory_region() into its sole caller (ioctl() API) KVM: Assert slots_lock is held when setting memory regions KVM: Add a dedicated API for setting KVM-internal memslots KVM: x86: Drop double-underscores from __kvm_set_memory_region() KVM: Disallow all flags for KVM-internal memslots arch/x86/kvm/x86.c | 7 ++++--- include/linux/kvm_host.h | 8 +++----- virt/kvm/kvm_main.c | 33 ++++++++++++++------------------- 3 files changed, 21 insertions(+), 27 deletions(-)
