Add a static assert to the KVM/VM/vCPU ioctl() helpers to verify that the size of the argument provided matches the expected size of the IOCTL. Because ioctl() ultimately takes a "void *", it's all too easy to pass in garbage and not detect the error until runtime. E.g. while working on a CPUID rework, selftests happily compiled when vcpu_set_cpuid() unintentionally passed the cpuid() function as the parameter to ioctl() (a local "cpuid" parameter was removed, but its use was not replaced with "vcpu->cpuid" as intended). Tweak a variety of benign issues that aren't compatible with the sanity check, e.g. passing a non-pointer for ioctls(). Note, static_assert() requires a string on older versions of GCC. Feed it an empty string to make the compiler happy. Signed-off-by: Sean Christopherson <seanjc@google.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
