Merge tag 'nfsd-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux

Pull nfsd updates from Chuck Lever:
"NFSD is finally able to offer write delegations to clients that open
files with O_WRONLY, thanks to patches from Dai Ngo. We're expecting
this to accelerate a few interesting corner cases.

The cap on the number of operations per NFSv4 COMPOUND has been
lifted. Now, clients that send COMPOUNDs containing dozens of
operations (for example, a long stream of LOOKUP operations to walk a
pathname in a single round trip) will no longer be rejected.

This release re-enables the ability for NFSD to perform NFSv4.2 COPY
operations asynchronously. This feature has been disabled to mitigate
the risk of denial-of-service when too many such requests arrive.

Many thanks to the contributors, reviewers, testers, and bug reporters
who participated during the v6.17 development cycle"

nfs_localio: change nfsd_file_put_local() to take a pointer to __rcu pointer

Instead of calling xchg() and unrcu_pointer() before
nfsd_file_put_local(), we now pass pointer to the __rcu pointer and call
xchg() and unrcu_pointer() inside that function.

Where unrcu_pointer() is currently called the internals of "struct
nfsd_file" are not known and that causes older compilers such as gcc-8
to complain.

In some cases we have a __kernel (aka normal) pointer not an __rcu
pointer so we need to cast it to __rcu first. This is strictly a
weakening so no information is lost. Somewhat surprisingly, this cast
is accepted by gcc-8.

This has the pleasing result that the cmpxchg() which sets ro_file and
rw_file, and also the xchg() which clears them, are both now in the nfsd
code.

nfs_localio: always hold nfsd net ref with nfsd_file ref

Having separate nfsd_file_put and nfsd_file_put_local in struct
nfsd_localio_operations doesn't make much sense. The difference is that
nfsd_file_put doesn't drop a reference to the nfs_net which is what
keeps nfsd from shutting down.

Currently, if nfsd tries to shutdown it will invalidate the files stored
in the list from the nfs_uuid and this will drop all references to the
nfsd net that the client holds. But the client could still hold some
references to nfsd_files for active IO. So nfsd might think is has
completely shut down local IO, but hasn't and has no way to wait for
those active IO requests to complete.

So this patch changes nfsd_file_get to nfsd_file_get_local and has it
increase the ref count on the nfsd net and it replaces all calls to
->nfsd_put_file to ->nfsd_put_file_local.

It also changes ->nfsd_open_local_fh to return with the refcount on the
net elevated precisely when a valid nfsd_file is returned.

This means that whenever the client holds a valid nfsd_file, there will
be an associated count on the nfsd net, and so the count can only reach
zero when all nfsd_files have been returned.

nfs_local_file_put() is changed to call nfs_to_nfsd_file_put_local()
instead of replacing calls to one with calls to the other because this
will help a later patch which changes nfs_to_nfsd_file_put_local() to
take an __rcu pointer while nfs_local_file_put() doesn't.

Pull nfsd updates from Chuck Lever:
"Neil Brown contributed more scalability improvements to NFSD's open
file cache, and Jeff Layton contributed a menagerie of repairs to
NFSD's NFSv4 callback / backchannel implementation.

Mike Snitzer contributed a change to NFS re-export support that
disables support for file locking on a re-exported NFSv4 mount. This
is because NFSv4 state recovery is currently difficult if not
impossible for re-exported NFS mounts. The change aims to prevent data
integrity exposures after the re-export server crashes.

Work continues on the evolving NFSD netlink administrative API.
