Pull nfsd updates from Chuck Lever:
"I'm thrilled to announce that the Linux in-kernel NFS server now
offers NFSv4 write delegations. A write delegation enables a client to
cache data and metadata for a single file more aggressively, reducing
network round trips and server workload. Many thanks to Dai Ngo for
contributing this facility, and to Jeff Layton and Neil Brown for
reviewing and testing it.

This release also sees the removal of all support for DES- and
triple-DES-based Kerberos encryption types in the kernel's SunRPC
implementation. These encryption types have been deprecated by the
Internet community for years and are considered insecure. This change
affects both the in-kernel NFS client and server.

The server's UDP and TCP socket transports have now fully adopted
David Howells' new bio_vec iterator so that no more than one sendmsg()
call is needed to transmit each RPC message. In particular, this helps
kTLS optimize record boundaries when sending RPC-with-TLS replies, and
it takes the server a baby step closer to handling file I/O via
folios.

We've begun work on overhauling the SunRPC thread scheduler to remove
a costly linked-list walk when looking for an idle RPC service thread
to wake. The pre-requisites are included in this release. Thanks to
Neil Brown for his ongoing work on this improvement"

Merge tag 'nfsd-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux

Pull nfsd updates from Chuck Lever:
"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"

SUNRPC: Enable rpcsec_gss_krb5.ko to be built without CRYPTO_DES

Because the DES block cipher has been deprecated by Internet
standard, highly secure configurations might require that DES
support be blacklisted or not installed. NFS Kerberos should still
be able to work correctly with only the AES-based enctypes in that
situation.

Also note that MIT Kerberos has begun a deprecation process for DES
encryption types. Their README for 1.19.3 states:

> Beginning with the krb5-1.19 release, a warning will be issued
> if initial credentials are acquired using the des3-cbc-sha1
> encryption type. In future releases, this encryption type will
> be disabled by default and eventually removed.
>
> Beginning with the krb5-1.18 release, single-DES encryption
> types have been removed.

Aside from the CONFIG option name change, there are two important
policy changes:

1. The 'insecure enctype' group is now disabled by default.
Distributors have to take action to enable support for deprecated
enctypes. Implementation of these enctypes will be removed in a
future kernel release.

2. des3-cbc-sha1 is now considered part of the 'insecure enctype'
group, having been deprecated by RFC 8429, and is thus disabled
by default

After this patch is applied, SunRPC support can be built with
Kerberos 5 support but without CRYPTO_DES enabled in the kernel.
And, when these enctypes are disabled, the Linux kernel's SunRPC
RPCSEC GSS implementation fully complies with BCP 179 / RFC 6649
and BCP 218 / RFC 8429.
