      KVM: selftests: Remove duplicate guest mode handling · 52200d0d
      Peter Xu authored
      Remove the duplication code in run_test() of dirty_log_test because
      after some reordering of functions now we can directly use the outcome
      of vm_create().
      
      Meanwhile, with the new VM_MODE_PXXV48_4K, we can safely revert
      b442324b too where we stick the x86_64 PA width to 39 bits for
      dirty_log_test.

      KVM: selftests: Introduce VM_MODE_PXXV48_4K · 567a9f1e
      Peter Xu authored
      The naming VM_MODE_P52V48_4K is explicit but unclear when used on
      x86_64 machines, because x86_64 machines are having various physical
      address width rather than some static values.  Here's some examples:
      
        - Intel Xeon E3-1220:  36 bits
        - Intel Core i7-8650:  39 bits
        - AMD   EPYC 7251:     48 bits
      
      All of them are using 48 bits linear address width but with totally
      different physical address width (and most of the old machines should
      be less than 52 bits).
      
      Let's create a new guest mode called VM_MODE_PXXV48_4K for current
      x86_64 tests and make it as the default to replace the old naming of
      VM_MODE_P52V48_4K because it shows more clearly that the PA width is
      not really a constant.  Meanwhile we also stop assuming all the x86
      machines are having 52 bits PA width but instead we fetch the real
      vm->pa_bits from CPUID 0x80000008 during runtime.
      
      We currently make this exclusively used by x86_64 but no other arch.
      
      As a slight touch up, moving DEBUG macro from dirty_log_test.c to
      kvm_util.h so lib can use it too.

      KVM: selftests: Create VM earlier for dirty log test · 338eb298
      Peter Xu authored
      Since we've just removed the dependency of vm type in previous patch,
      now we can create the vm much earlier.  Note that to move it earlier
      we used an approximation of number of extra pages but it should be
      fine.
      
      This prepares for the follow up patches to finally remove the
      duplication of guest mode parsings.

      KVM: selftests: Move vm type into _vm_create() internally · 12c386b2
      Peter Xu authored
      Rather than passing the vm type from the top level to the end of vm
      creation, let's simply keep that as an internal of kvm_vm struct and
      decide the type in _vm_create().  Several reasons for doing this:
      
      - The vm type is only decided by physical address width and currently
        only used in aarch64, so we've got enough information as long as
        we're passing vm_guest_mode into _vm_create(),
      
      - This removes a loop dependency between the vm->type and creation of
        vms.  That's why now we need to parse vm_guest_mode twice sometimes,
        once in run_test() and then again in _vm_create().  The follow up
        patches will move on to clean up that as well so we can have a
        single place to decide guest machine types and so.
      
      Note that this patch will slightly change the behavior of aarch64
      tests in that previously most vm_create() callers will directly pass
      in type==0 into _vm_create() but now the type will depend on
      vm_guest_mode, however it shouldn't affect any user because all
      vm_create() users of aarch64 will be using VM_MODE_DEFAULT guest
      mode (which is VM_MODE_P40V48_4K) so at last type will still be zero.

      KVM: x86: announce KVM_CAP_HYPERV_ENLIGHTENED_VMCS support only when it is available · 5a0165f6
      Vitaly Kuznetsov authored
      It was discovered that after commit 65efa61d ("selftests: kvm: provide
      common function to enable eVMCS") hyperv_cpuid selftest is failing on AMD.
      The reason is that the commit changed _vcpu_ioctl() to vcpu_ioctl() in the
      test and this one can't fail.
      
      Instead of fixing the test is seems to make more sense to not announce
      KVM_CAP_HYPERV_ENLIGHTENED_VMCS support if it is definitely missing
      (on svm and in case kvm_intel.nested=0).

      Pull SafeSetID fix from Micah Morton:
       "Jann Horn sent some patches to fix some bugs in SafeSetID for 5.3.
        After he had done his testing there were a couple small code tweaks
        that went in and caused this bug.
      
        From what I can see SafeSetID is broken in 5.3 and crashes the kernel
        every time during initialization if you try to use it. I came across
        this bug when backporting Jann's changes for 5.3 to older kernels
        (4.14 and 4.19). I've tested on a Chrome OS device with those kernels
        and verified that this change fixes things.
      
        It doesn't seem super useful to have this bake in linux-next, since it
        is completely broken in 5.3 and nobody noticed"

      Pull selinux updates from Paul Moore:
      
       - Add LSM hooks, and SELinux access control hooks, for dnotify,
         fanotify, and inotify watches. This has been discussed with both the
         LSM and fs/notify folks and everybody is good with these new hooks.
      
       - The LSM stacking changes missed a few calls to current_security() in
         the SELinux code; we fix those and remove current_security() for
         good.
      
       - Improve our network object labeling cache so that we always return
         the object's label, even when under memory pressure. Previously we
         would return an error if we couldn't allocate a new cache entry, now
         we always return the label even if we can't create a new cache entry
         for it.
      
       - Convert the sidtab atomic_t counter to a normal u32 with
         READ/WRITE_ONCE() and memory barrier protection.
      
       - A few patches to policydb.c to clean things up (remove forward
         declarations, long lines, bad variable names, etc)
