The new nfsdcld will do a one-time "upgrade" where it searches for
records from nfsdcltrack and the legacy tracking during startup.
Legacy records will be prefixed with the string "hash:", which we need
to strip off before adding to the reclaim_str_hashtbl. When legacy
records are encountered, set the new cn_has_legacy flag in the cld_net.
When this flag is set, if the search for a reclaim record based on the
client name string fails, then do a second search based on the hash of
the name string.
Note that if there are legacy records then the grace period will not
be lifted early via the tracking of RECLAIM_COMPLETEs.

When using nfsdcld for NFSv4 client tracking, track the number of

When nfsdcld was released, it was quickly deprecated in favor of the
nfsdcltrack usermodehelper, so as to not require another running daemon.
That prevents NFSv4 clients from reclaiming locks from nfsd's running in
containers, since neither nfsdcltrack nor the legacy client tracking
code work in containers.
This commit un-deprecates the use of nfsdcld, with one twist: we will
populate the reclaim_str_hashtbl on startup.
During client tracking initialization, do an upcall ("GraceStart") to
nfsdcld to get a list of clients from the database. nfsdcld will do
one downcall with a status of -EINPROGRESS for each client record in
the database, which in turn will cause an nfs4_client_reclaim to be
added to the reclaim_str_hashtbl. When complete, nfsdcld will do a
final downcall with a status of 0.
This will save nfsd from having to do an upcall to the daemon during
nfs4_check_open_reclaim() processing.
Even though nfsdcld was quickly deprecated, there is a very small chance
of old nfsdcld daemons running in the wild. These will respond to the
new "GraceStart" upcall with -EOPNOTSUPP, in which case we will log a
message and fall back to the original nfsdcld tracking ops (now called
nfsd4_cld_tracking_ops_v0).

If no handler (such as rpc.mountd) has opened
a cache 'channel', the sunrpc cache responds to
all lookup requests with -ENOENT. This is particularly
important for the auth.unix.gid cache which is
optional.
If the channel was open briefly and an upcall was written to it,
this upcall remains pending even when the handler closes the
channel. When an upcall is pending, the code currently
doesn't check if there are still listeners, it only performs
that check before sending an upcall.
As the cache treads a recently closes channel (closed less than
30 seconds ago) as "potentially still open", there is a
reasonable sized window when a request can become pending
in a closed channel, and thereby block lookups indefinitely.
This can easily be demonstrated by running
cat /proc/net/rpc/auth.unix.gid/channel
and then trying to mount an NFS filesystem from this host. It
will block indefinitely (unless mountd is run with --manage-gids,
or krb5 is used).
When cache_check() finds that an upcall is pending, it should
perform the "cache_listeners_exist()" exist test. If no
listeners do exist, the request should be negated.
With this change in place, there can still be a 30second wait on
mount, until the cache gives up waiting for a handler to come
back, but this is much better than an indefinite wait.

When a blocked NFS lock is "awoken" we send a callback to the server and
then wake any hosts waiting on it. If a client attempts to get a lock
and then drops off the net, we could end up waiting for a long time
until we end up waking locks blocked on that request.
So, wake any other waiting lock requests before sending the callback.
Do this by calling locks_delete_block in a new "prepare" phase for
CB_NOTIFY_LOCK callbacks.

After a blocked nfsd file_lock request is deleted, knfsd will send a
callback to the client and then free the request. Commit 16306a61d3
("fs/locks: always delete_block after waiting.") changed it such that
locks_delete_block is always called on a request after it is awoken,
but that patch missed fixing up blocked nfsd request handling.
Call locks_delete_block on the block to wake up any locks still blocked
on the nfsd lock request before freeing it. Some of its callers already
do this however, so just remove those calls.

If there are multiple callbacks queued, waiting for the callback
slot when the callback gets shut down, then they all currently
end up acting as if they hold the slot, and call
nfsd4_cb_sequence_done() resulting in interesting side-effects.
In addition, the 'retry_nowait' path in nfsd4_cb_sequence_done()
causes a loop back to nfsd4_cb_prepare() without first freeing the
slot, which causes a deadlock when nfsd41_cb_get_slot() gets called
a second time.
This patch therefore adds a boolean to track whether or not the
callback did pick up the slot, so that it can do the right thing
in these 2 cases.

nfsv3 readdir request size can be larger than PAGE_SIZE. So if the
directory been read is large enough, we can use multiple pages
in rq_respages. Update buffer count and page pointers like we do
in readdirplus to make this happen.
Now listing a directory within 3000 files will panic because we
are counting in a wrong way and would write on random page.

A recent commit added a call to cache_fresh_locked()
when an expired item was found.
The call sets the CACHE_VALID flag, so it is important
that the item actually is valid.
There are two ways it could be valid:
1/ If ->update has been called to fill in relevant content
2/ if CACHE_NEGATIVE is set, to say that content doesn't exist.
An expired item that is waiting for an update will be neither.
Setting CACHE_VALID will mean that a subsequent call to cache_put()
will be likely to dereference uninitialised pointers.
So we must make sure the item is valid, and we already have code to do
that in try_to_negate_entry(). This takes the hash lock and so cannot
be used directly, so take out the two lines that we need and use them.
Now cache_fresh_locked() is certain to be called only on
a valid item.

gpio: exar: add a check for the return value of ida_simple_get fails
If userspace doesn't end the input with a newline (which can easily
happen if the write happens from a C program that does write(fd,
iface, strlen(iface))), we may end up including garbage from a
previous, longer value in the device_name. For example
# cat device_name
# printf 'eth12' > device_name
# cat device_name
eth12
# printf 'eth3' > device_name
# cat device_name
eth32
I highly doubt anybody is relying on this behaviour, so switch to
simply copying the bytes (we've already checked that size is <
IFNAMSIZ) and unconditionally zero-terminate it; of course, we also
still have to strip a trailing newline.
This is also preparation for future patches.

Here are some small staging driver fixes for 5.1-rc3, and one driver
removal.
The biggest thing here is the removal of the mt7621-eth driver as a
"real" network driver was merged in 5.1-rc1 for this hardware, so this
old driver can now be removed.
Other than that, there are just a number of small fixes, all resolving
reported issues and some potential corner cases for error handling
paths.
All of these have been in linux-next with no reported issues.

Here are some binder, habanalabs, and vboxguest driver fixes for
5.1-rc3.
The Binder fixes resolve some reported issues found by testing, first by
the selinux developers, and then earlier today by syzbot.
The habanalabs fixes are all minor, resolving a number of tiny things.
The vboxguest patches are a bit larger. They resolve the fact that
virtual box decided to change their api in their latest release in a way
that broke the existing kernel code, despite saying that they were never
going to do that. So this is a bit of a "new feature", but is good to
get merged so that 5.1 will work with the latest release. The changes
are not large and of course virtual box "swears" they will not break
this again, but no one is holding their breath here.

Pull SCSI fixes from James Bottomley:
"Thirteen fixes, seven of which are for IBM fibre channel and three
additional for fairly serious bugs in drivers (qla2xxx, mpt3sas,
aacraid).
Of the three core fixes, the most significant is probably the missed
run queue causing an indefinite hang. The others are fixing a
potential use after free on device close and silencing an incorrect
warning"
