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. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmox5BcACgkQM2qzM29m f5eFJQ//QlyZCt0BlzeBrGHJB41yrMZkZGSJsPaZPfvNnjIQPwd6WH3d6i1vygvC HgC+KTF/8LLuFx14m17M6FBCujixNoknMLyp74vRPZOSCoXilP/jzlDoVWwgwv73 E0AkKXyij1QFToIh7NP/ClX+Zpc9yoCR3/RWri7ud400z1mlvFBk8NA7E6pb+AzT 89lKFgkubSQVnHFRdIAgb3G/AkZzt35O6hzPA6thtwkb8MS2knE27L9HNc2InQ/K 71QjQj09052tcXOJRHlg7Xj6AeCyPteCqxsA03qMo2mmqRiSBVV+5y6czawxdHk8 yt9cDloUu+ZynhH4qktv3i8lX7dPcYNfIcMora71LAswDE5Ud3c/EG6zleA5DnzX cgUaS8VkbfLyHAlvPRl9DroizsBgrr/qjuwUqewoY/wJCpyEBtCGRxLKI0MS2Ivo BvgdXE74uCyOGZ2EYOqaocGejMtXt1GGpf2Wj5/jyDDUABEhwTptoTIlbBcWQbf6 7ZRlxjwx7kaMMtmag0ZEhkh42ujoHF3NzNDDD4hY1M6twgF+0uofJPLb5eK4JZak FDKV38iiwqq2/bWOKGnaFQBV1Hn/0569rxFku2Z0O+wWNBXhiZ5wezw84GoYaCt/ AYSDFYnI4FOrHurdmgZUyr04W2toXWN6mV3IqbDIIx5eXyWEKvU= =xAeq -----END PGP SIGNATURE----- Merge tag 'nfsd-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "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.
