by Greg Kroah-Hartman

I'm announcing the release of the 5.15.181 kernel. All users of the 5.15 kernel series must upgrade. The updated 5.15.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-5.15.y and can be browsed at the normal kernel.org git web browser: https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary thanks, greg k-h ------------ Documentation/scsi/libsas.rst | 2 Makefile | 5 arch/arm64/boot/dts/mediatek/mt8173.dtsi | 6

Please backport 980a573621ea to 6.12, 6.14

by Dionna Amalie Glaze

980a573621ea ("tpm: Make chip->{status,cancel,req_canceled} opt") This is a dependent commit for the series of patches to add the AMD SEV-SNP SVSM vTPM device driver. Kernel 6.11 added SVSM support, but not support for the critical component for boot integrity that follows the SEV-SNP threat model. That series https://lore.kernel.org/all/20250410135118.133240-1-sgarzare@redhat.com/ is applied at tip but is not yet in the mainline. I have confirmed that this patch applies cleanly. Stefano's patch series needs a minor tweak to the first patch due to the changed surrounding function declarations in arch/x86/include/asm/sev.h https://github.com/deeglaze/amdese-linux/commits/vtpm612/ I've independently tested the patches. -- -Dionna Glaze, PhD, CISSP, CCSP (she/her)

When the guest accesses a DR and host userspace isn't debugging the guest, KVM disables DR interception and loads the guest's values into hardware on VM-Enter and saves them on VM-Exit. This allows the guest to access DRs at will, e.g. so that a sequence of DR accesses to configure a breakpoint only generates one VM-Exit. For DR0-DR3, the logic/behavior is identical between VMX and SVM, and also identical between KVM_DEBUGREG_BP_ENABLED (userspace debugging the guest) and KVM_DEBUGREG_WONT_EXIT (guest using DRs), and so KVM handles loading DR0-DR3 in common code, _outside_ of the core kvm_x86_ops.vcpu_run() loop. But for DR6, the guest's value doesn't need to be loaded into hardware for KVM_DEBUGREG_BP_ENABLED, and SVM provides a dedicated VMCB field whereas VMX requires software to manually load the guest value, and so loading the guest's value into DR6 is handled by {svm,vmx}_vcpu_run(), i.e. is done _inside_ the core run loop. Unfortunately, saving the guest values on VM-Exit is initiated by common x86, again outside of the core run loop. If the guest modifies DR6 (in hardware, when DR interception is disabled), and then the next VM-Exit is a fastpath VM-Exit, KVM will reload hardware DR6 with vcpu->arch.dr6 and clobber the guest's actual value. The bug shows up primarily with nested VMX because KVM handles the VMX preemption timer in the fastpath, and the window between hardware DR6 being modified (in guest context) and DR6 being read by guest software is orders of magnitude larger in a nested setup. E.g. in non-nested, the VMX preemption timer would need to fire precisely between #DB injection and the #DB handler's read of DR6, whereas with a KVM-on-KVM setup, the window where hardware DR6 is "dirty" extends all the way from L1 writing DR6 to VMRESUME (in L1).

When the guest accesses a DR and host userspace isn't debugging the guest, KVM disables DR interception and loads the guest's values into hardware on VM-Enter and saves them on VM-Exit. This allows the guest to access DRs at will, e.g. so that a sequence of DR accesses to configure a breakpoint only generates one VM-Exit. For DR0-DR3, the logic/behavior is identical between VMX and SVM, and also identical between KVM_DEBUGREG_BP_ENABLED (userspace debugging the guest) and KVM_DEBUGREG_WONT_EXIT (guest using DRs), and so KVM handles loading DR0-DR3 in common code, _outside_ of the core kvm_x86_ops.vcpu_run() loop. But for DR6, the guest's value doesn't need to be loaded into hardware for KVM_DEBUGREG_BP_ENABLED, and SVM provides a dedicated VMCB field whereas VMX requires software to manually load the guest value, and so loading the guest's value into DR6 is handled by {svm,vmx}_vcpu_run(), i.e. is done _inside_ the core run loop. Unfortunately, saving the guest values on VM-Exit is initiated by common x86, again outside of the core run loop. If the guest modifies DR6 (in hardware, when DR interception is disabled), and then the next VM-Exit is a fastpath VM-Exit, KVM will reload hardware DR6 with vcpu->arch.dr6 and clobber the guest's actual value. The bug shows up primarily with nested VMX because KVM handles the VMX preemption timer in the fastpath, and the window between hardware DR6 being modified (in guest context) and DR6 being read by guest software is orders of magnitude larger in a nested setup. E.g. in non-nested, the VMX preemption timer would need to fire precisely between #DB injection and the #DB handler's read of DR6, whereas with a KVM-on-KVM setup, the window where hardware DR6 is "dirty" extends all the way from L1 writing DR6 to VMRESUME (in L1).

The bug shows up primarily with nested VMX because KVM handles the VMX preemption timer in the fastpath, and the window between hardware DR6 being modified (in guest context) and DR6 being read by guest software is orders of magnitude larger in a nested setup. E.g. in non-nested, the VMX preemption timer would need to fire precisely between #DB injection and the #DB handler's read of DR6, whereas with a KVM-on-KVM setup, the window where hardware DR6 is "dirty" extends all the way from L1 writing DR6 to VMRESUME (in L1).

[PATCH v5] Restrict devmem for confidential VMs

by Dan Williams

Changes since v3 [1] (note v4 was a partial re-roll, but more feedback came in requiring a v5): - Fix a kbuild robot report for a missing header include of cc_platform.h - Switch to selecting STRICT_DEVMEM and IOSTRICT_DEVMEM rather than "depends on". (Naveen) - Clarify the "SEPT violation" vs "crash" and other changelog fixups for devmem maintainers and other arch maintainers. (Dave) - Drop patch numbering since patch2 is a fix and has no dependencies on patch1 [1]: http://lore.kernel.org/174491711228.1395340.3647010925173796093.stgit@dwill… --- The original response to Nikolay's report of a "crash" (unhandled SEPT violation) triggered by /dev/mem access to private memory was "let's just turn off /dev/mem". After some machinations of x86_platform_ops to block a subset of problematic access, spelunking the history of devmem_is_allowed() returning "2" to enable some compatibility benefits while blocking access, and discovering that userspace depends buggy kernel behavior for mmap(2) of the first 1MB of memory on x86, the proposal has circled back to "disable /dev/mem". Require both STRICT_DEVMEM and IO_STRICT_DEVMEM for x86 confidential guests to close /dev/mem hole while still allowing for userspace mapping of PCI MMIO as long as the kernel and userspace are not mapping the range at the same time. The range_is_allowed() cleanup is not strictly necessary, but might as well close a 17 year-old "TODO".
