9fc2f99030
Two significant security enhancements are part of this release:
* NFSD's RPC header encoding and decoding, including RPCSEC GSS
and gssproxy header parsing, has been overhauled to make it
more memory-safe.
* Support for Kerberos AES-SHA2-based encryption types has been
added for both the NFS client and server. This provides a clean
path for deprecating and removing insecure encryption types
based on DES and SHA-1. AES-SHA2 is also FIPS-140 compliant, so
that NFS with Kerberos may now be used on systems with fips
enabled.
In addition to these, NFSD is now able to handle crossing into an
auto-mounted mount point on an exported NFS mount. A number of
fixes have been made to NFSD's server-side copy implementation.
RPC metrics have been converted to per-CPU variables. This helps
reduce unnecessary cross-CPU and cross-node memory bus traffic,
and significantly reduces noise when KCSAN is enabled.

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.
