Subject: [GIT PULL] KVM/arm64 fixes for 6.11, round #1 From: Oliver Upton To: Paolo Bonzini Cc: Marc Zyngier , Alexander Potapenko , Mark Brown , Fuad Tabba , Zenghui Yu , Takahiro Itazuri , Sebastian Ott , Danilo Krummrich , kvm@vger.kernel.org, kvmarm@lists.linux.dev Date: Fri, 9 Aug 2024 01:12:19 -0700 Hi Paolo, Decent bit of fixes this time around. The most noteworthy among these is probably Marc's vgic fix that closes a race which can precipitate a UAF, as seen w/ syskaller. Please pull. -- Thanks, Oliver The following changes since commit 8400291e289ee6b2bf9779ff1c83a291501f017b: Linux 6.11-rc1 (2024-07-28 14:19:55 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm.git tags/kvmarm-fixes-6.11-1 for you to fetch changes up to 9eb18136af9fe4dd688724070f2bfba271bd1542: KVM: arm64: vgic: Hold config_lock while tearing down a CPU interface (2024-08-08 16:58:22 +0000) ---------------------------------------------------------------- KVM/arm64 fixes for 6.11, round #1 - Use kvfree() for the kvmalloc'd nested MMUs array - Set of fixes to address warnings in W=1 builds - Make KVM depend on assembler support for ARMv8.4 - Fix for vgic-debug interface for VMs without LPIs - Actually check ID_AA64MMFR3_EL1.S1PIE in get-reg-list selftest - Minor code / comment cleanups for configuring PAuth traps - Take kvm->arch.config_lock to prevent destruction / initialization race for a vCPU's CPUIF which may lead to a UAF ---------------------------------------------------------------- Danilo Krummrich (1): KVM: arm64: free kvm->arch.nested_mmus with kvfree() Fuad Tabba (1): KVM: arm64: Tidying up PAuth code in KVM Marc Zyngier (2): KVM: arm64: Enforce dependency on an ARMv8.4-aware toolchain KVM: arm64: vgic: Hold config_lock while tearing down a CPU interface Mark Brown (1): KVM: selftests: arm64: Correct feature test for S1PIE in get-reg-list Sebastian Ott (3): KVM: arm64: fix override-init warnings in W=1 builds KVM: arm64: fix kdoc warnings in W=1 builds KVM: arm64: vgic: fix unexpected unlock sparse warnings Takahiro Itazuri (1): docs: KVM: Fix register ID of SPSR_FIQ Zenghui Yu (1): KVM: arm64: vgic-debug: Exit the iterator properly w/o LPI Documentation/virt/kvm/api.rst | 2 +- arch/arm64/include/asm/kvm_ptrauth.h | 2 +- arch/arm64/kvm/Kconfig | 1 + arch/arm64/kvm/Makefile | 3 +++ arch/arm64/kvm/arm.c | 15 +++++---------- arch/arm64/kvm/hyp/include/hyp/switch.h | 1 - arch/arm64/kvm/hyp/nvhe/Makefile | 2 ++ arch/arm64/kvm/hyp/nvhe/switch.c | 5 ++--- arch/arm64/kvm/hyp/vhe/Makefile | 2 ++ arch/arm64/kvm/nested.c | 2 +- arch/arm64/kvm/vgic/vgic-debug.c | 5 +++-- arch/arm64/kvm/vgic/vgic-init.c | 3 +-- arch/arm64/kvm/vgic/vgic-irqfd.c | 7 ++++--- arch/arm64/kvm/vgic/vgic-its.c | 18 +++++++++++------- arch/arm64/kvm/vgic/vgic-v3.c | 2 +- arch/arm64/kvm/vgic/vgic.c | 2 +- arch/arm64/kvm/vgic/vgic.h | 2 +- tools/testing/selftests/kvm/aarch64/get-reg-list.c | 4 ++-- 18 files changed, 42 insertions(+), 36 deletions(-) .
