      KVM: SVM: Do not terminate SEV-ES guests on GHCB validation failure · ad5b3532
      Tom Lendacky authored
      Currently, an SEV-ES guest is terminated if the validation of the VMGEXIT
      exit code or exit parameters fails.
      
      The VMGEXIT instruction can be issued from userspace, even though
      userspace (likely) can't update the GHCB. To prevent userspace from being
      able to kill the guest, return an error through the GHCB when validation
      fails rather than terminating the guest. For cases where the GHCB can't be
      updated (e.g. the GHCB can't be mapped, etc.), just return back to the
      guest.
      
      The new error codes are documented in the lasest update to the GHCB
      specification.

      Use kvzalloc() to allocate KVM's buffer for SEV-ES's GHCB scratch area so
      that KVM falls back to __vmalloc() if physically contiguous memory isn't
      available.  The buffer is purely a KVM software construct, i.e. there's
      no need for it to be physically contiguous.

      Sean Christopherson authored
      Return appropriate error codes if setting up the GHCB scratch area for an
      SEV-ES guest fails.  In particular, returning -EINVAL instead of -ENOMEM
      when allocating the kernel buffer could be confusing as userspace would
      likely suspect a guest issue.
