The pointer to svm_cpu_data in struct vcpu_svm looks interesting from the point of view of accessing it after vmexit, when the GSBASE is still containing the guest value. However, despite existing since the very first commit of drivers/kvm/svm.c (commit 6aa8b732, "[PATCH] kvm: userspace interface", 2006-12-10), it was never set to anything. Ignore the opportunity to fix a 16 year old "bug" and delete it; doing things the "harder" way makes it possible to remove more old cruft. Reviewed-by:

Continue moving accesses to struct vcpu_svm to vmenter.S. Reducing the number of arguments limits the chance of mistakes due to different registers used for argument passing in 32- and 64-bit ABIs; pushing the VMCB argument and almost immediately popping it into a different register looks pretty weird. 32-bit ABI is not a concern for __svm_sev_es_vcpu_run() which is 64-bit only; however, it will soon need @svm to save/restore SPEC_CTRL so stay consistent with __svm_vcpu_run() and let them share the same prototype. No functional change intended. Cc: stable@vger.kernel.org Fixes: a149180f ("x86: Add magic AMD return-thunk") Reviewed-by:

32-bit ABI uses RAX/RCX/RDX as its argument registers, so they are in the way of instructions that hardcode their operands such as RDMSR/WRMSR or VMLOAD/VMRUN/VMSAVE. In preparation for moving vmload/vmsave to __svm_vcpu_run(), keep the pointer to the struct vcpu_svm in %rdi. In particular, it is now possible to load svm->vmcb01.pa in %rax without clobbering the struct vcpu_svm pointer. No functional change intended.

Since registers are reachable through vcpu_svm, and we will need to access more fields of that struct, pass it instead of the regs[] array. No functional change intended. Cc: stable@vger.kernel.org Fixes: a149180f ("x86: Add magic AMD return-thunk") Reviewed-by:

This already removes an ugly #include "" from asm-offsets.c, but especially it avoids a future error when trying to define asm-offsets for KVM's svm/svm.h header. This would not work for kernel/asm-offsets.c, because svm/svm.h includes kvm_cache_regs.h which is not in the include path when compiling asm-offsets.c. The problem is not there if the .c file is in arch/x86/kvm. Suggested-by:

kvm_zap_gfn_range() must be called in an SRCU read-critical section, but there is no SRCU annotation in __kvm_set_or_clear_apicv_inhibit().

The SRCU read lock is not technically required when no Shadow MMUs are in use, since the TDP MMU walks the paging structures from the roots and does not need to look up GFN translations in the memslots, but make the SRCU locking unconditional for simplicty. In most cases, the SRCU locking is taken care of in the vCPU run loop, but when called through other ioctls (such as KVM_SET_GUEST_DEBUG) there is no srcu_read_lock. Tested: ran tools/testing/selftests/kvm/x86_64/debug_regs on a DBG build. This patch causes the suspicious RCU warning to disappear. Note that the warning is hit in __kvm_zap_rmaps(), so kvm_memslots_have_rmaps() must return true in order for this to repro (i.e. the TDP MMU must be off or nesting in use.) Reported-by:

Ignore guest CPUID for host userspace writes to the DEBUGCTL MSR, KVM's ABI is that setting CPUID vs. state can be done in any order, i.e. KVM allows userspace to stuff MSRs prior to setting the guest's CPUID that makes the new MSR "legal". Keep the vmx_get_perf_capabilities() check for guest writes, even though it's technically unnecessary since the vCPU's PERF_CAPABILITIES is consulted when refreshing LBR support. A future patch will clean up vmx_get_perf_capabilities() to avoid the RDMSR on every call, at which point the paranoia will incur no meaningful overhead. Note, prior to vmx_get_perf_capabilities() checking that the host fully supports LBRs via x86_perf_get_lbr(), KVM effectively relied on intel_pmu_lbr_is_enabled() to guard against host userspace enabling LBRs on platforms without full support.

Fold vmx_supported_debugctl() into vcpu_supported_debugctl(), its only caller. Setting bits only to clear them a few instructions later is rather silly, and splitting the logic makes things seem more complicated than they actually are. Opportunistically drop DEBUGCTLMSR_LBR_MASK now that there's a single reference to the pair of bits. The extra layer of indirection provides no meaningful value and makes it unnecessarily tedious to understand what KVM is doing. No functional change. Signed-off-by:

There are two capabilities related to ring-based dirty page tracking: KVM_CAP_DIRTY_LOG_RING and KVM_CAP_DIRTY_LOG_RING_ACQ_REL. Both are supported by x86. However, arm64 supports KVM_CAP_DIRTY_LOG_RING_ACQ_REL only when the feature is supported on arm64. The userspace doesn't have to enable the advertised capability, meaning KVM_CAP_DIRTY_LOG_RING can be enabled on arm64 by userspace and it's wrong. Fix it by double checking if the capability has been advertised prior to enabling it. It's rejected to enable the capability if it hasn't been advertised.

Pull random number generator fix from Jason Donenfeld: "One fix from Jean-Philippe Brucker, addressing a regression in which early boot code on ARM64 would use the non-_early variant of the arch_get_random family of functions, resulting in the architectural random number generator appearing unavailable during that early phase of boot. The fix simply changes arch_get_random*() to arch_get_random*_early(). This distinction between these two functions is a bit of an old wart I'm not a fan of, and for 6.2 I'll see if I can make obsolete the _early variant, so that one function does the right thing in all contexts without overhead" * tag 'random-6.1-rc3-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: random: use arch_get_random*_early() in random_init()
