Linus Torvalds 3dc7c00116 NFSD 7.2 Release Notes
Jeff Layton wired up netlink upcalls for the auth.unix.ip and
 auth.unix.gid caches in SunRPC and the svc_export and nfsd.fh
 caches in NFSD. The new kernel-user API is more extensible and
 lays the groundwork for retiring the old pipe interface.
 
 The default NFS r/w block size rises to 4MB on hosts with at least
 16GB of RAM, reducing per-RPC overhead on fast networks. Smaller
 machines keep their previously computed default, and the value
 remains tunable through /proc/fs/nfsd/max_block_size.
 
 Chuck Lever converted the server's RPCSEC GSS Kerberos code to the
 kernel's shared crypto/krb5 library. The conversion retires and
 removes SunRPC's bespoke implementation of Kerberos v5, but keeps
 RPCSEC GSS-API.
 
 Continuing the xdrgen migration that converted the NLMv4 server XDR
 layer in v7.1, Chuck Lever converted the NLM version 3 server-side
 XDR layer from hand-written C to xdrgen-generated code. As with the
 NLMv4 conversion in v7.1, the goals are improved memory safety,
 lower maintenance burden, and groundwork for generation of Rust code
 for this layer instead of C.
 
 Chuck Lever fixed an issue where lingering NFSv4 state pins a
 mounted file system after it is unexported. A new netlink-based
 mechanism can now release NLM locks and NFSv4 state by client
 address, by filesystem, and by export. Now an administrator can
 quiesce an export cleanly before unmounting it.
 
 The remaining patches are bug fixes, clean-ups, and minor
 optimizations, including a batch of memory-leak and use-after-free
 fixes in the ACL, lockd, and TLS handshake paths, many of them
 reported by Chris Mason. Sincere thanks to all contributors,
 reviewers, testers, and bug reporters who participated in the v7.2
 NFSD development cycle.
