sunrpc: Remove gss_{de,en}crypt_xdr_buf deadcode (2025-01-21 15:30:01 -0500)
----------------------------------------------------------------
NFSD 6.14 Release Notes
Jeff Layton contributed an implementation of NFSv4.2+ attribute
delegation, as described here:
https://www.ietf.org/archive/id/draft-ietf-nfsv4-delstid-08.html
This interoperates with similar functionality introduced into the
Linux NFS client in v6.11. An attribute delegation permits an NFS
client to manage a file's mtime, rather than flushing dirty data to
the NFS server so that the file's mtime reflects the last write,
which is considerably slower.
Neil Brown contributed dynamic NFSv4.1 session slot table resizing.
This facility enables NFSD to increase or decrease the number of
slots per NFS session depending on server memory availability. More
session slots means greater parallelism.
Chuck Lever fixed a long-standing latent bug where NFSv4 COMPOUND
encoding screws up when crossing a page boundary in the encoding
buffer. This is a zero-day bug, but hitting it is rare and depends
on the NFS client implementation. The Linux NFS client does not
happen to trigger this issue.
A variety of bug fixes and other incremental improvements fill out
the list of commits in this release. Great thanks to all
contributors, reviewers, testers, and bug reporters who participated
during this development cycle.
