We changed this around in f135af1041f ('nfsd: reorganize nfsd_create')
so "dchild" can't be an error pointer any more. Also, dchild can't be
NULL here (and dput would already handle this even if it was).

vfs_{create,mkdir,mknod} each begin with a call to may_create(), which
returns EEXIST if the object already exists.
This check is therefore unnecessary.
(In the NFSv2 case, nfsd_proc_create also has such a check. Contrary to
RFC 1094, our code seems to believe that a CREATE of an existing file
should succeed. I'm leaving that behavior alone.)

There's some odd logic in nfsd_create() that allows it to be called with
the parent directory either locked or unlocked. The only already-locked
caller is NFSv2's nfsd_proc_create(). It's less confusing to split out
the unlocked case into a separate function which the NFSv2 code can call
directly.
Also fix some comments while we're here.

Create and other nfsd ops generally assume we can call lookup_one_len on
inodes with S_IFDIR set. Al says that this assumption isn't true in
general, though it should be for the filesystem objects nfsd sees.
Add a check just to make sure our assumption isn't violated.
Remove a couple checks for i_op->lookup in create code.

lookup_one_len already has this check.
The only effect of this patch is to return access instead of perm in the
0-length-filename case. I actually prefer nfserr_perm (or _inval?), but
I doubt anyone cares.
The isdotent check seems redundant too, but I worry that some client
might actually care about that strange nfserr_exist error.

When doing a create (mkdir/mknod) on a name, it's worth
checking the name exists first before returning EACCES in case
the directory is not writeable by the user.
This makes return values on the client more consistent
regardless of whenever the entry there is cached in the local
cache or not.
Another positive side effect is certain programs only expect
EEXIST in that case even despite POSIX allowing any valid
error to be returned.

i.e. an immediate close of the socket after initialisation.
The culprit appears to be the test at the end of svc_tcp_init, which
checks if the newly created socket is in the TCP_ESTABLISHED state,
and immediately closes it if not. The evidence appears to suggest that
the socket might still be in the SYN_RECV state at this time.
The fix is to check for both states, and then to add a check in
svc_tcp_state_change() to ensure we don't close the socket when
it transitions into TCP_ESTABLISHED.

If the underlying filesystem supports multiple layout types, then there
is little reason not to advertise that fact to clients and let them
choose what type to use.
Turn the ex_layout_type field into a bitfield. For each supported
layout type, we set a bit in that field. When the client requests a
layout, ensure that the bit for that layout type is set. When the
client requests attributes, send back a list of supported types.

nfsd4_release_lockowner finds a lock owner that has no lock state,
and drops cl_lock. Then release_lockowner picks up cl_lock and
unhashes the lock owner.
During the window where cl_lock is dropped, I don't see anything
preventing a concurrent nfsd4_lock from finding that same lock owner
and adding lock state to it.
Move release_lockowner() into nfsd4_release_lockowner and hang onto
the cl_lock until after the lock owner's state cannot be found
again.
Found by inspection, we don't currently have a reproducer.

The current server rpc tcp code attempts to predict how much writeable
socket space will be available to a given RPC call before accepting it
for processing. On a 40GigE network, we've found this throttles
individual clients long before the network or disk is saturated. The
server may handle more clients easily, but the bandwidth of individual
clients is still artificially limited.
Instead of trying (and failing) to predict how much writeable socket space
will be available to the RPC call, just fall back to the simple model of
deferring processing until the socket is uncongested.
This may increase the risk of fast clients starving slower clients; in
such cases, the previous patch allows setting a hard per-connection
limit.

This addresses the conundrum referenced in RFC5661 18.35.3,
and will allow clients to return state to the server using the
machine credentials.
The biggest part of the problem is that we need to allow the client
to send a compound op with integrity/privacy on mounts that don't
have it enabled.
Add server support for properly decoding and using spo_must_enforce
and spo_must_allow bits. Add support for machine credentials to be
used for CLOSE, OPEN_DOWNGRADE, LOCKU, DELEGRETURN,
and TEST/FREE STATEID.
Implement a check so as to not throw WRONGSEC errors when these
operations are used if integrity/privacy isn't turned on.
Without this, Linux clients with credentials that expired while holding
delegations were getting stuck in an endless loop.

(Another one for the f_path debacle.)
ltp fcntl33 testcase caused an Oops in selinux_file_send_sigiotask.
The reason is that generic_add_lease() used filp->f_path.dentry->inode
while all the others use file_inode(). This makes a difference for files
opened on overlayfs since the former will point to the overlay inode the
latter to the underlying inode.
So generic_add_lease() added the lease to the overlay inode and
generic_delete_lease() removed it from the underlying inode. When the file
was released the lease remained on the overlay inode's lock list, resulting
in use after free.

Commit fe742fd4f90f ("Revert "btrfs: switch to ->iterate_shared()"")
backed out the conversion to ->iterate_shared() for Btrfs because the
delayed inode handling in btrfs_real_readdir() is racy. However, we can
still do readdir in parallel if there are no delayed nodes.
This is a temporary fix which upgrades the shared inode lock to an
exclusive lock only when we have delayed items until we come up with a
more complete solution. While we're here, rename the
btrfs_{get,put}_delayed_items functions to make it very clear that
they're just for readdir.
Tested with xfstests and by doing a parallel kernel build:
while make tinyconfig && make -j4 && git clean dqfx; do
:
done
along with a bunch of parallel finds in another shell:
while true; do
for ((i=0; i<4; i++)); do
