David S. Miller 4874fb9484 Merge branch 'tls-rx-nopad-and-backlog-flushing'
Jakub Kicinski says:

====================
tls: rx: nopad and backlog flushing

This small series contains the two changes I've been working
towards in the previous ~50 patches a couple of months ago.

The first major change is the optional "nopad" optimization.
Currently TLS 1.3 Rx performs quite poorly because it does
not support the "zero-copy" or rather direct decrypt to a user
space buffer. Because of TLS 1.3 record padding we don't
know if a record contains data or a control message until
we decrypt it. Most records will contain data, tho, so the
optimization is to try the decryption hoping its data and
retry if it wasn't.

The performance gain from doing that is significant (~40%)
but if I'm completely honest the major reason is that we
call skb_cow_data() on the non-"zc" path. The next series
will remove the CoW, dropping the gain to only ~10%.

The second change is to flush the backlog every 128kB.

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.
