svcrdma: wake sq waiters when the transport closes (2026-06-09 16:32:59 -0400)
----------------------------------------------------------------
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.
