Linus Torvalds 9fc2f99030 NFSD 6.3 Release Notes
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.
