* kvm-arm64/raz-sysregs: : . : Simplify the handling of RAZ register, removing pointless indirections. : . KVM: arm64: Replace get_raz_id_reg() with get_raz_reg() KVM: arm64: Use get_raz_reg() for userspace reads of PMSWINC_EL0 KVM: arm64: Return early from read_id_reg() if register is RAZ Signed-off-by:Marc Zyngier <maz@kernel.org>

Reading a RAZ ID register isn't different from reading any other RAZ register, so get rid of get_raz_id_reg() and replace it with get_raz_reg(), which does the same thing, but does it without going through two layers of indirection. No functional change. Suggested-by:

PMSWINC_EL0 is a write-only register and was initially part of the VCPU register state, but was later removed in commit 7a3ba309 ("KVM: arm64: Remove PMSWINC_EL0 shadow register"). To prevent regressions, the register was kept accessible from userspace as Read-As-Zero (RAZ). The read function that is used to handle userspace reads of this register is get_raz_id_reg(), which, while technically correct, as it returns 0, it is not semantically correct, as PMSWINC_EL0 is not an ID register as the function name suggests. Add a new function, get_raz_reg(), to use it as the accessor for PMSWINC_EL0, as to not conflate get_raz_id_reg() to handle other types of registers. No functional change intended. Signed-off-by:

If read_id_reg() is called for an ID register which is Read-As-Zero (RAZ), it initializes the return value to zero, then goes through a list of registers which require special handling before returning the final value. By not returning as soon as it checks that the register should be RAZ, the function creates the opportunity for bugs, if, for example, a patch changes a register to RAZ (like has happened with PMSWINC_EL0 in commit 11663111), but doesn't remove the special handling from read_id_reg(); or if a register is RAZ in certain situations, but readable in others. Return early to make it impossible for a RAZ register to be anything other than zero. Reviewed-by:

Unconditionally "source" the generic KVM Kconfig instead of wrapping it with KVM=y. A future patch will select HAVE_KVM so that referencing HAVE_KVM in common kernel code doesn't break, and because KVM=y and HAVE_KVM=n is weird. Source the generic KVM Kconfig unconditionally so that HAVE_KVM and KVM don't end up with a circular dependency. Note, all but one of generic KVM's "configs" are of the HAVE_XYZ nature, and the one outlier correctly takes a dependency on CONFIG_KVM, i.e. the generic Kconfig is intended to be included unconditionally. No functional change intended. Signed-off-by:

Although KVM can be compiled out of the kernel, it cannot be disabled at runtime. Allow this possibility by introducing a new mode that will prevent KVM from initialising. This is useful in the (limited) circumstances where you don't want KVM to be available (what is wrong with you?), or when you want to install another hypervisor instead (good luck with that).

Add a new test into vgic_init which checks that the first vcpu fails to run if there is not sufficient REDIST space below the addressable IPA range. This only applies to the KVM_VGIC_V3_ADDR_TYPE_REDIST legacy API as the required REDIST space is not know when setting the DIST region. Note that using the REDIST_REGION API results in a different check at first vcpu run: that the number of redist regions is enough for all vcpus. And there is already a test for that case in, the first step of test_v3_new_redist_regions. Reviewed-by:

Add tests for checking that KVM returns the right error when trying to set GICv2 CPU interfaces or GICv3 Redistributors partially above the addressable IPA range. Also tighten the IPA range by replacing KVM_CAP_ARM_VM_IPA_SIZE with the IPA range currently configured for the guest (i.e., the default). The check for the GICv3 redistributor created using the REDIST legacy API is not sufficient as this new test only checks the check done using vcpus already created when setting the base. The next commit will add the missing test which verifies that the KVM check is done at first vcpu run. Signed-off-by:

Verify that the redistributor regions do not extend beyond the VM-specified IPA range (phys_size). This can happen when using KVM_VGIC_V3_ADDR_TYPE_REDIST or KVM_VGIC_V3_ADDR_TYPE_REDIST_REGIONS with: base + size > phys_size AND base < phys_size Add the missing check into vgic_v3_alloc_redist_region() which is called when setting the regions, and into vgic_v3_check_base() which is called when attempting the first vcpu-run. The vcpu-run check does not apply to KVM_VGIC_V3_ADDR_TYPE_REDIST_REGIONS because the regions size is known before the first vcpu-run. Note that using the REDIST_REGIONS API results in a different check, which already exists, at first vcpu run: that the number of redist regions is enough for all vcpus. Finally, this patch also enables some extra tests in vgic_v3_alloc_redist_region() by calculating "size" early for the legacy redist api: like checking that the REDIST region can fit all the already created vcpus.

After pKVM has been 'finalised' using the __pkvm_prot_finalize hypercall, the calling CPU will have a Stage-2 translation enabled to prevent access to memory pages owned by EL2. Although this forms a significant part of the process to deprivilege the host kernel, we also need to ensure that the hypercall interface is reduced so that the EL2 code cannot, for example, be re-initialised using a new set of vectors. Re-order the hypercalls so that only a suffix remains available after finalisation of pKVM. Cc: Marc Zyngier <maz@kernel.org> Cc: Quentin Perret <qperret@google.com> Signed-off-by:

Will Deacon authored
__pkvm_prot_finalize() completes the deprivilege of the host when pKVM is in use by installing a stage-2 translation table for the calling CPU. Issuing the hypercall multiple times for a given CPU makes little sense, but in such a case just return early with -EPERM rather than go through the whole page-table dance again.

If the __pkvm_prot_finalize hypercall returns an error, we WARN but fail to propagate the failure code back to kvm_arch_init().

The stub hypercalls provide mechanisms to reset and replace the EL2 code, so uninstall them once pKVM has been initialised in order to ensure the integrity of the hypervisor code. To ensure pKVM initialisation remains functional, split cpu_hyp_reinit() into two helper functions to separate usage of the stub from usage of pkvm hypercalls either side of __pkvm_init on the boot CPU.

Will Deacon authored
When pKVM is enabled, the hypervisor code at EL2 and its data structures are inaccessible to the host kernel and cannot be torn down or replaced as this would defeat the integrity properies which pKVM aims to provide. Furthermore, the ABI between the host and EL2 is flexible and private to whatever the current implementation of KVM requires and so booting a new kernel with an old EL2 component is very likely to end in disaster. In preparation for uninstalling the hyp stub calls which are relied upon to reset EL2, disable kexec and hibernation in the host when protected KVM is enabled.

__KVM_HOST_SMCCC_FUNC_* is a royal pain, as there is a fair amount of churn around these #defines, and we avoid making it an enum only for the sake of the early init, low level code that requires __KVM_HOST_SMCCC_FUNC___kvm_hyp_init to be usable from assembly. Let's be brave and turn everything but this symbol into an enum, using a bit of arithmetic to avoid any overlap. Acked-by:

In commit b212921b ("elf: don't use MAP_FIXED_NOREPLACE for elf executable mappings") we still leave MAP_FIXED_NOREPLACE in place for load_elf_interp. Unfortunately, this will cause kernel to fail to start with: 1 (init): Uhuuh, elf segment at 00003ffff7ffd000 requested but the memory is mapped already Failed to execute /init (error -17) The reason is that the elf interpreter (ld.so) has overlapping segments. readelf -l ld-2.31.so Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flags Align LOAD 0x0000000000000000 0x0000000000000000 0x0000000000000000 0x000000000002c94c 0x000000000002c94c R E 0x10000 LOAD 0x000000000002dae0 0x000000000003dae0 0x000000000003dae0 0x00000000000021e8 0x0000000000002320 RW 0x10000 LOAD 0x000000000002fe00 0x000000000003fe00 0x000000000003fe00 0x00000000000011ac 0x0000000000001328 RW 0x10000 The reason for this problem is the same as described in commit ad55eac7 ("elf: enforce MAP_FIXED on overlaying elf segments").

The objtool warning that the kvm instruction emulation code triggered wasn't very useful: arch/x86/kvm/emulate.o: warning: objtool: __ex_table+0x4: don't know how to handle reloc symbol type: kvm_fastop_exception in that it helpfully tells you which symbol name it had trouble figuring out the relocation for, but it doesn't actually say what the unknown symbol type was that triggered it all. In this case it was because of missing type information (type 0, aka STT_NOTYPE), but on the whole it really should just have printed that out as part of the message. Because if this warning triggers, that's very much the first thing you want to know - why did reloc2sec_off() return failure for that symbol? So rather than just saying you can't handle some type of symbol without saying what the type _was_, just print out the type number too.

The recent change to make objtool aware of more symbol relocation types (commit 24ff6525: "objtool: Teach get_alt_entry() about more relocation types") also added another check, and resulted in this objtool warning when building kvm on x86: arch/x86/kvm/emulate.o: warning: objtool: __ex_table+0x4: don't know how to handle reloc symbol type: kvm_fastop_exception The reason seems to be that kvm_fastop_exception() is marked as a global symbol, which causes the relocation to ke kept around for objtool. And at the same time, the kvm_fastop_exception definition (which is done as an inline asm statement) doesn't actually set the type of the global, which then makes objtool unhappy. The minimal fix is to just not mark kvm_fastop_exception as being a global symbol. It's only used in that one compilation unit anyway, so it was always pointless. That's how all the other local exception table labels are done. I'm not entirely happy about the kinds of games that the kvm code plays with doing its own exception handling, and the fact that it confused objtool is most definitely a symptom of the code being a bit too subtle and ad-hoc. But at least this trivial one-liner makes objtool no longer upset about what is going on.
