Pointers to VMbus packets sent by Hyper-V are used by the hv_sock driver
within the guest VM. Hyper-V can send packets with erroneous values or
modify packet fields after they are processed by the guest. To defend
against these scenarios, copy the incoming packet after validating its
length and offset fields using hv_pkt_iter_{first,next}(). Use
HVS_PKT_LEN(HVS_MTU_SIZE) to initialize the buffer which holds the
copies of the incoming packets. In this way, the packet can no longer
be modified by the host.

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.
