NFSD: add support for NFSv4 write delegation

The NFSv4 server currently supports read delegation using VFS lease
which is implemented using file_lock. 

This patch series add write delegation support for NFSv4 server by:

    . remove the check for F_WRLCK in generic_add_lease to allow
      file_lock to be used for write delegation.  

    . grant write delegation for OPEN with NFS4_SHARE_ACCESS_WRITE
      if there is no conflict with other OPENs.

    . add XDR support for sending and receiving CB_GETATTR.

    . handle GETATTR from another client on a file that has outstanding
      write delegation by using CB_GETATTR to get the latest change_info
      and size for the GETATTR reply.

Write delegation conflict with another OPEN, REMOVE, RENAME and SETATTR
are handled the same as read delegation using notify_change, try_break_deleg.

Changes since v1:

[PATCH 3/4] NFSD: add supports for CB_GETATTR callback
- remove WARN_ON_ONCE from encode_bitmap4
- replace decode_bitmap4 with xdr_stream_decode_uint32_array
- replace xdr_inline_decode and xdr_decode_hyper in decode_cb_getattr
   with xdr_stream_decode_u64. Also remove the un-needed likely().
- modify signature of encode_cb_getattr4args to take pointer to
   nfs4_cb_fattr
- replace decode_attr_length with xdr_stream_decode_u32
- rename decode_cb_getattr to decode_cb_fattr4
- fold the initialization of cb_cinfo and cb_fsize into decode_cb_fattr4
- rename ncf_cb_cinfo to ncf_cb_change to avoid confusion of cindo usage
  in fs/nfsd/nfs4xdr.c
- correct NFS4_dec_cb_getattr_sz and update size description

[PATCH 4/4] NFSD: handle GETATTR conflict with write delegation
- change nfs4_handle_wrdeleg_conflict returns __be32 to fix test robot
- change ncf_cb_cinfo to ncf_cb_change to avoid confusion of cindo usage
  in fs/nfsd/nfs4xdr.c

[PATCH v2 1/4] locks: allow support for write delegation

[Dai Ngo]

Remove the check for F_WRLCK in generic_add_lease to allow file_lock
to be used for write delegation.

First consumer is NFSD.

[PATCH v2 2/4] NFSD: enable support for write delegation

[Dai Ngo]

This patch grants write delegation for OPEN with NFS4_SHARE_ACCESS_WRITE
if there is no conflict with other OPENs.

[PATCH v2 4/4] NFSD: handle GETATTR conflict with write delegation

[Dai Ngo]

If the GETATTR request on a file that has write delegation in effect
and the request attributes include the change info and size attribute
then the request is handled as below:

Server sends CB_GETATTR to client to get the latest change info and file
size. If these values are the same as the server's cached values then
the GETATTR proceeds as normal.

If either the change info or file size is different from the server's
cached values, or the file was already marked as modified, then:

   . update time_modify and time_metadata into file's metadata
     with current time

   . encode GETATTR as normal except the file size is encoded with
     the value returned from CB_GETATTR

   . mark the file as modified

If the CB_GETATTR fails for any reasons, the delegation is recalled
and NFS4ERR_DELAY is returned for the GETATTR.

Shouldn't that be a bool? I don't think you actually need this variable
anyway, you can just open-code the ternary condition in the assignment.

I think you want (STATX_SIZE|STATX_CTIME|STATX_CHANGE_COOKIE) here
instead of BASIC_STATS. You might not get the change cookie otherwise,
even when it's supported.

When there is a write lease, then there cannot be any read leases, so
you don't need to walk the entire list here. Just check the first
element and see whether it's a write lease.

Yes, you're right that handling of GETATTR with delegations is not
required by the spec. The only benefit I see is that the server
provides a more accurate state of the file as whether the file has
been changed/updated since the client's last GETATTR. This allows
the app on the client to take appropriate action (whatever that
might be) when sharing files among multiple clients.

From RFC 8881 10.4.3:

"It should be noted that the server is under no obligation to use
CB_GETATTR, and therefore the server MAY simply recall the delegation to
avoid its use."

As I see it, the main benefit is that you avoid having to recall a write
delegation when someone does a drive-by stat() on the file (e.g. due to
a "ls -l" in its parent directory).

That's not at all how I read that. To me, it sounds like it's saying
that the only alternative to implementing CB_GETATTR is to recall the
delegation. If that's not the case, then we should clarify that in the
spec.

The meaning of MAY is spelled out in RFC 2119. MAY does not mean
"the only alternative". I read this statement as alerting client
implementers that a compliant server is permitted to skip
CB_GETATTR, simply by recalling the delegation. Technically
speaking this compliance statement does not otherwise restrict
server behavior, though the author might have had something else
in mind.

I'm leery of the complexity that CB_GETATTR adds to NFSD and
the protocol. In addition, section 10.4 is riddled with errors,
albeit minor ones; that suggests this part of the protocol is
not well-reviewed.

It's not apparent how much gain is provided by CB_GETATTR.
IIRC NFSD can recall a delegation on the same nfsd thread as an
incoming request, so the turnaround for a recall from a local
client is going to be quick.

It would be good to know how many other server implementations
support CB_GETATTR.

I'm rather leaning towards postponing 3/4 and 4/4 and instead
taking a more incremental approach. Let's get the basic Write
delegation support in, and possibly add a counter or two to
find out how often a GETATTR on a write-delegated file results
in a delegation recall.

We can then take some time to disambiguate the spec language and
look at other implementations to see if this extra protocol is
really of value.

I think it would be good to understand whether Write delegation
without CB_GETATTR can result in a performance regression (say,
because the server is recalling delegations more often for a
given workload).

Ganesha has had write delegation and CB_GETATTR support for years.

Isn't CB_GETATTR the main benefit of a write delegation in the first
place? A write deleg doesn't really give any benefit otherwise, as you
can buffer writes anyway without one.

AIUI, the point of a write delegation is to allow other clients (and
potentially the server) to get up to date information on file sizes and
change attr when there is a single, active writer.

Without CB_GETATTR, your first stat() against the file will give you
fairly up to date info (since you'll have to recall the delegation), but
then you'll be back to the server just reporting the size and change
attr that it has at the time.

Does OnTAP support write delegation? I heard a rumor NetApp
disabled it because of the volume of customer calls involving
delegation with the Linux client, but that could be old news.

How about Solaris? My close contact with the Solaris NFS team
as the Linux NFS client implementation matured has colored my
experience with write delegation. It is complex and subtle.

The benefits of write delegation depend on the client implementation
and the workload. A client may use a write delegation to indicate
that it can handle locking requests for a file locally, for example.

Which is the current behavior, yes? As long as behavior is not
regressing, I don't foresee a problem with doing CB_GETATTR in 6.6
or later.

So far I have not run into any problem of NFS client using write
delegation. My testing so far, besides manual tests, were the delegation
tests in pynfs for 4.0 and 4.1 and nfstest_delegation test.

The nfstest_delegation result is:
1785 tests (1783 passed, 2 failed)

The 2 failed test is regarding whether the NFSv4 server should allow
the client to use write delegation state to do READ.

This is what the Linux NFS client does, handling locking requests for a
file locally if the file has write delegation.

I think defer the handling of GETATTR with CB_GETATTR until 6.6 is okay
so we can get some runtime with write delegation to have some confident
with its stability.

For now we just return the (potentially stale) file attribute available
at the server. It should not cause significant problem since there won't
be any real application depends on this feature yet, at least on the Linux
NFS server.

ONTAP supports delegations (though i'm not sure if the default is on.
So I'm not sure if the current recommendation is not to enable it due
to known issues). ONTAP does not send any CB_GETATTR. Whether or not
it makes it a non-spec compliant I'm not sure as the spec isn't too
clear (at least to me). We as a linux team did raise the issue with
ONTAP about them not implementing CB_GETATTR. But so far no complaints
have been made about lacking CB_GETATTR.

I raised the question because I was really curious what real
usefulness really comes from it? or perhaps what are the expectations
that the server can guarantee or what conclusions can the 2nd client
can make? As I mentioned in my initial posting, the information that
the server (and then the 2nd client) gets is (possibly) stale as soon
as it gets it because the client with delegation keeps writing to the
file after getting the CB_GETATTR. The complexity that's being added
to the server (and to the client) doesn't seem to be worth it.

I thought the benefits of delegations have always been the savings
gotten from doing local opens and locking. Open is an expensive server
operation.

Because the (linux) client is flushing the writes exactly the same way
whether or not it's holding a delegation so the server's view is the
same (with or without delegation). Now of course I'm speaking about
the linux client so one can speculate what if there is a client
implementation that uses delegation to do more caching? Sure... But I
still don't really see how the 2nd client can expect to rely/make
critical decisions based on the information it gets from a GETATTR.

The only advantage of CB_GETATTR is that it allows you to determine
whether or not the client holding the delegation is also holding cached
writes. Since we pretty much always rely on close-to-open semantics
anyway, the benefit of implementing it is pretty marginal.

Personally, I see CB_GETATTR as being more useful once servers start
implementing the timestamp/attribute delegations as per
https://datatracker.ietf.org/doc/draft-ietf-nfsv4-delstid/ 
Since those delegations allow the client to be authoritative for the
atime and mtime timestamps, and to also cache those, then CB_GETATTR
becomes a necessity in order to correctly timestamp writes that have
already been committed to the file.
