If the GVA is NOT valid, there is no # guest-side page table walk and so stuffing paging related metadata # is nonsensical # # - Fix a bug where KVM would incorrectly synthesize a nested VM-Exit # instead of emulating posted interrupt delivery to L2 # # - Add a lockdep assertion to detect unsafe accesses of vmcs12 # structures # # - Harden eVMCS loading against an impossible NULL pointer deref # (really truly should be impossible) # # - Minor SGX fix and a cleanup # # - Misc cleanups # # Generic: # # - Register KVM's cpuhp and syscore callbacks when enabling # virtualization in hardware, as the sole purpose of said callbacks # is to disable and re-enable virtualization as needed # # - Enable virtualization when KVM is loaded, not right before the # first VM is created # # Together with the previous change, this simplifies a lot the logic # of the callbacks, because their very existence implies # virtualization is enabled # # - Fix a bug that results in KVM prematurely exiting to userspace for # coalesced MMIO/PIO in many cases, clean up the related code, and # add a testcase # # - Fix a bug in kvm_clear_guest() where it would trigger a buffer # overflow _if_ the gpa+len crosses a page boundary, which thankfully # is guaranteed to not happen in the current code base. Add WARNs in # more helpers that read/write guest memory to detect similar bugs # # Selftests: # # - Fix a goof that caused some Hyper-V tests to be skipped when run on # bare metal, i.e. NOT in a VM # # - Add a regression test for KVM's handling of SHUTDOWN for an SEV-ES # guest # # - Explicitly include one-off assets in .gitignore. Past Sean was # completely wrong about not being able to detect missing .gitignore # entries # # - Verify userspace single-stepping works when KVM happens to handle a # VM-Exit in its fastpath # # - Misc cleanups" # # * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (127 commits) # Documentation: KVM: fix warning in "make htmldocs" # s390: Enable KVM_S390_UCONTROL config in debug_defconfig # selftests: kvm: s390: Add VM run test case # KVM: SVM: let alternatives handle the cases when RSB filling is required # KVM: VMX: Set PFERR_GUEST_{FINAL,PAGE}_MASK if and only if the GVA is valid # KVM: x86/mmu: Use KVM_PAGES_PER_HPAGE() instead of an open coded equivalent # KVM: x86/mmu: Add KVM_RMAP_MANY to replace open coded '1' and '1ul' literals # KVM: x86/mmu: Fold mmu_spte_age() into kvm_rmap_age_gfn_range() # KVM: x86/mmu: Morph kvm_handle_gfn_range() into an aging specific helper # KVM: x86/mmu: Honor NEED_RESCHED when zapping rmaps and blocking is allowed # KVM: x86/mmu: Add a helper to walk and zap rmaps for a memslot # KVM: x86/mmu: Plumb a @can_yield parameter into __walk_slot_rmaps() # KVM: x86/mmu: Move walk_slot_rmaps() up near for_each_slot_rmap_range() # KVM: x86/mmu: WARN on MMIO cache hit when emulating write-protected gfn # KVM: x86/mmu: Detect if unprotect will do anything based on invalid_list # KVM: x86/mmu: Subsume kvm_mmu_unprotect_page() into the and_retry() version # KVM: x86: Rename reexecute_instruction()=>kvm_unprotect_and_retry_on_failure() # KVM: x86: Update retry protection fields when forcing retry on emulation failure # KVM: x86: Apply retry protection to "unprotect on failure" path # KVM: x86: Check EMULTYPE_WRITE_PF_TO_SP before unprotecting gfn # ... # < /opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 3efc57369a0ce8f76bf0804f7e673982384e4ac9 # make -s -j 40 ARCH=um O=/kisskb/build/linus_allmodconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 allmodconfig WARNING: unmet direct dependencies detected for MODVERSIONS Depends on [n]: MODULES [=y] && !COMPILE_TEST [=y] Selected by [y]: -
