When reading or writing a guest page, WARN and bail if offset+len would result in a read to a different page so that KVM bugs are more likely to be detected, and so that any such bugs are less likely to escalate to an out-of-bounds access. E.g. if userspace isn't using guard pages and the target page is at the end of a memslot. Note, KVM already hardens itself in similar APIs, e.g. in the "cached" variants, it's just the vanilla APIs that are playing with fire.

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 reStructuredText 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.
