We can't do skb_walk_frags() on the input skbs, because
the input skbs is really just a pointer to the tcp read
queue. We need to bound the "is decrypted" check by the
amount of data in the message.
Note that the walk in tls_device_reencrypt() is after a
CoW so the skb there is safe to walk. Actually in the
current implementation it can't have frags at all, but
whatever, maybe one day it will.

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.
