[LU-5491] lnet_ioctl must verify userspace ioctl buffer

Mon, 31 Jan 2022 03:48:19 +0000

I was just inspecting some lnet patch and noticed that lnet_ioctl->LNetCtl do quite a few unchecked userspace acess.
It looks like doing the check that the ioctl data is valid in lnet_ioctl is the most easy way to fix this.
