[PATCH v6 0/9] vfs/nfsd: clean up handling of i_version counter

[PATCH v6 0/9] vfs/nfsd: clean up handling of i_version counter

[Jeff Layton]

v6: add support for STATX_ATTR_VERSION_MONOTONIC
    add patch to expose i_version counter to userland
    patches to update times/version after copying write data

An updated set of i_version handling changes! I've dropped the earlier
ext4 patches since Ted has picked up the relevant ext4 ones.

This set is based on linux-next, to make sure we don't collide with the
statx DIO alignment patches, and some other i_version cleanups that are
in flight.  I'm hoping those land in 6.1.

There are a few changes since v5, mostly centered around adding
STATX_ATTR_VERSION_MONOTONIC. I've also re-added the patch to expose
STATX_VERSION to userland via statx. What I'm proposing should now
(mostly) conform to the semantics I layed out in the manpage patch I
sent recently [1].

Finally, I've added two patches to make __generic_file_write_iter and
ext4 update the c/mtime after copying file data instead of before, which
Neil pointed out makes for better cache-coherency handling. Those should
take care of ext4 and tmpfs. xfs and btrfs will need to make the same
changes.

One thing I'm not sure of is what we should do if update_times fails
after an otherwise successful write. Should we just ignore that and move
on (and maybe WARN)? Return an error? Set a writeback error? What's the
right recourse there?

I'd like to go ahead and get the first 6 patches from this series into
linux-next fairly soon, so if anyone has objections, please speak up!

[PATCH v6 2/9] iversion: clarify when the i_version counter must be updated

[Jeff Layton]

The i_version field in the kernel has had different semantics over
the decades, but NFSv4 has certain expectations. Update the comments
in iversion.h to describe when the i_version must change.

[PATCH v6 3/9] vfs: plumb i_version handling into struct kstat

[Jeff Layton]

From: Jeff Layton <jlayton@redhat.com>

The NFS server has a lot of special handling for different types of
change attribute access, depending on what sort of inode we have. In
most cases, it's doing a getattr anyway and then fetching that value
after the fact.

Rather that do that, add a new STATX_VERSION flag that is a kernel-only
symbol (for now). If requested and getattr can implement it, it can fill
out this field. For IS_I_VERSION inodes, add a generic implementation in
vfs_getattr_nosec. Take care to mask STATX_VERSION off in requests from
userland and in the result mask.

Eventually if we decide to make this available to userland, we can just
designate a field for it in struct statx, and move the STATX_VERSION
definition to the uapi header.

[PATCH v6 4/9] nfs: report the inode version in getattr if requested

[Jeff Layton]

Allow NFS to report the i_version in getattr requests. Since the cost to
fetch it is relatively cheap, do it unconditionally and just set the
flag if it looks like it's valid. Also, conditionally enable the
MONOTONIC flag when the server reports its change attr type as such.

When getattr requests the STX_VERSION, request the full gamut of caps
(similarly to how ctime is handled). When the change attribute seems to
be valid, return it in the ino_version field and set the flag in the
reply mask. Also, unconditionally enable STATX_ATTR_VERSION_MONOTONIC.

[PATCH v6 6/9] nfsd: use the getattr operation to fetch i_version

[Jeff Layton]

Now that we can call into vfs_getattr to get the i_version field, use
that facility to fetch it instead of doing it in nfsd4_change_attribute.

Neil also pointed out recently that IS_I_VERSION directory operations
are always logged, and so we only need to mitigate the rollback problem
on regular files. Also, we don't need to factor in the ctime when
reexporting NFS or Ceph.

Set the STATX_VERSION (and BTIME) bits in the request when we're dealing
with a v4 request. Then, instead of looking at IS_I_VERSION when
generating the change attr, look at the result mask and only use it if
STATX_VERSION is set. With this change, we can drop the fetch_iversion
export operation as well.

Move nfsd4_change_attribute into nfsfh.c, and change it to only factor
in the ctime if it's a regular file and the fs doesn't advertise
STATX_ATTR_VERSION_MONOTONIC.

[PATCH v6 7/9] vfs: expose STATX_VERSION to userland

[Jeff Layton]

From: Jeff Layton <jlayton@redhat.com>

Claim one of the spare fields in struct statx to hold a 64-bit inode
version attribute. When userland requests STATX_VERSION, copy the
value from the kstat struct there, and stop masking off
STATX_ATTR_VERSION_MONOTONIC.

Update the test-statx sample program to output the change attr and
MountId.

[PATCH v6 8/9] vfs: update times after copying data in __generic_file_write_iter

[Jeff Layton]

The c/mtime and i_version currently get updated before the data is
copied (or a DIO write is issued), which is problematic for NFS.

READ+GETATTR can race with a write (even a local one) in such a way as
to make the client associate the state of the file with the wrong change
attribute. That association can persist indefinitely if the file sees no
further changes.

Move the setting of times to the bottom of the function in
__generic_file_write_iter and only update it if something was
successfully written.

If the time update fails, log a warning once, but don't fail the write.
All of the existing callers use update_time functions that don't fail,
so we should never trip this.

[PATCH v6 9/9] ext4: update times after I/O in write codepaths

[Jeff Layton]

The times currently get updated before the data is copied (or the DIO is
issued) which is problematic for NFSv4. A READ+GETATTR could race with a
write in such a way to make the client associate the state of the file
with the wrong change attribute, and that association could persist
indefinitely if the file sees no further changes.

For this reason, it's better to bump the times and change attribute
after the data has been copied or the DIO write issued.

This patch is doing some heavy lifting. I'd prefer to see it split
up to improve bisectability:

1. Move nfsd4_change_attribute() to fs/nfsd/nfsfh.c -- no functional changes

2. Change nfsd4_change_attribute() and vfs_getattr() call sites

3. Eliminate .fetch_iversion

Since fh_fill_post_attrs() calls nfsd4_change_attribute() as its
next step, don't you need to set STATX_VERSION here too?

I kind of hate the way we're handling both NFSv3 and NFSv4 post_attr
here, it's pretty difficult to reason about.

Reverse christmas tree, please.

Would it hurt to set BTIME and VERSION unconditionally?

A pedantic note, but I think necessary because so many people still
get this wrong when it comes to filesystems and IO: synchronous !=
persistent.

Ext4 and XFS both use *asynchronous journalling* - they journal
changes first to memory buffers, and only make those recorded
changes persistent when they hit internal checkpoint thresholds or
something external requires persistence to be guaranteed.

->commit_metadata is the operation filesystems provide the NFS
server to *guarantee persistence*. This allows filesystems to use
asynchronous journalling for most operations, right up to the point
the NFS server requires a change to be persistent. "synchronous
operation" is a side effect of guaranteeing persistence on some
filesytems and storage media, whereas "synchronous operation"
does not provide any guarantee of persistence...

IOWs, please talk about persistence guarantees the NFS server
application requires and implements, not about the operations (or
the nature of the operations) that may be performed by the
underlying filesystems to provide that persistence guarantee.

Cheers,

Dave.

This solution is wrong for several reasons:

1. There is still file_update_time() in ->page_mkwrite() so you haven't
    solved the problem completely
2. The other side of the coin is that post crash state is more likely to end
    up data changes without mtime/ctime change

If I read the problem description correctly, then a solution that invalidates
the NFS cache before AND after the write would be acceptable. Right?
Would an extra i_version bump after the write solve the race?

Right. I don't think there is a way to solve the problem vs. mmap.
Userland can write to a writeable mmap'ed page at any time and we'd
never know. We have to specifically carve out mmap as an exception here.
I'll plan to add something to the manpage patch for this.

Is this really something filesystems rely on? I suppose the danger is
that some cached data gets written to disk before the write returns and
the inode on disk never gets updated.

But...isn't that a danger now? Some of the cached data could get written
out and the updated inode just never makes it to disk before a crash
(AFAIU). I'm not sure that this increases our exposure to that problem.

I based this patch on Neil's assertion that updating the time before an
operation was pointless if we were going to do it afterward. The NFS
client only really cares about seeing it change after a write.

Doing both would be fine from a correctness standpoint, and in most
cases, the second would be a no-op anyway since a query would have to
race in between the two for that to happen.

FWIW, I think we should update the m/ctime and version at the same time.
If the version changes, then there is always the potential that a timer
tick has occurred. So, that would translate to a second call to
file_update_time in here.

The downside of bumping the times/version both before and after is that
these are hot codepaths, and we'd be adding extra operations there. Even
in the case where nothing has changed, we'd have to call
inode_needs_update_time a second time for every write. Is that worth the
cost?

You are correct that that danger exists, but it only exists for overwriting
to allocated blocks.

For writing to new blocks, mtime change is recorded in transaction
before the block mapping is recorded in transaction so there is no
danger in this case (before your patch).

Also, observing size change without observing mtime change
after crash seems like a very bad outcome that may be possible
after your change.

These are just a few cases that I could think of, they may be filesystem
dependent, but my gut feeling is that if you remove the time update before
the operation, that has been like that forever, a lot of s#!t is going to float
for various filesystems and applications.

And it is not one of those things that are discovered  during rc or even
stable kernel testing - they are discovered much later when users start to
realize their applications got bogged up after crash, so it feels like to me
like playing with fire.

Pointless to NFS client maybe.
Whether or not this is not changing user behavior for other applications
is up to you to prove and I doubt that you can prove it because I doubt
that it is true.

Is there a practical cost for iversion bump AFTER write as I suggested?
If you NEED m/ctime update AFTER write and iversion update is not enough
then I did not understand from your commit message why that is.

Maybe we should split i_version updates from ctime updates.

While it isn't true that ctime updates have happened before the write
"forever" it has been true since 2.3.43[1] which is close to forever.

For ctime there doesn't appear to be a strong specification of when the
change happens, so history provides a good case for leaving it before.
For i_version we want to provide clear and unambiguous semantics.
Performing 2 updates makes the specification muddy.

So I would prefer a single update for i_version, performed after the
change becomes visible.  If that means it has to be separate from ctime,
then so be it.

you could possible make the "I_VERSION_QUERIED already set" case inline
and the "needs to be set" case out-of-line, but it probably isn't worth
it.

POSIX doesn't (that I can see) describe when the ctime changes w.r.t
when the file changes.  For i_version we do want to specify that
i_version change is not visible before the file change is visible.
So this goes beyond the POSIX mandate.  I might be worth making that
explicit.
But this patch is nonetheless an improvement, so:

Above does not mention STATX_ATTR_VERSION_MONOTONIC, but it appears in
that patch - which is confusing.
But the patch is good, so

This looks wrong.
1/ it includes the I_VERSION_QUERIED bit, which should be hidden.
2/ it doesn't set that bit.

I understand that the bit was already set when the generic code called
inode_query_iversion(), but it might have changed if we needed to
refresh the attrs.

I'm beginning to think I shouldn't have approved the 3/9 patch.  The
stat->version shouldn't be set in vfs_getattr_nosec() - maybe in
generic_fillattr(), but not a lot of point.

So if the server tells us that the change attrs is based on time
metadata, we accept that it will be monotonic (and RFC7862 encourages
this), even though we seem to worry about timestamps going backwards
(which we know that can)...  Interesting.

I would really rather that the fs got to make this decision.
If it can guarantee that the i_version is monotonic even over a crash
(which is probably can for directory, and might need changes to do for
files) then it sets STATX_ATTR_VERSION_MONOTONIC and nfsd trusts it
completely.
If it cannot, then it doesn't set the flag.
i.e. the S_ISREG() test should be in the filesystem, not in nfsd.

Why hex? not decimal?  I don't really care but it seems like an odd choice.

NFS (and Ceph), do not set the SB_I_VERSION flag and they don't use the
QUERIED bit. These are "server managed" implementations of i_version.
The server is responsible for incrementing the value, and we just store
the result in the i_version field and present it when needed. That's why
the patch for NFS is using the "raw" API.

I followed suit from nfs_inode_attrs_cmp(). It seems to treat any value
that isn't UNDEFINED as MONOTONIC, though it does use a less strict
comparator for NFS4_CHANGE_TYPE_IS_TIME_METADATA. It may make sense to
carve that out as an exception.

This is probably an indicator that we need a more strict definition for
STATX_ATTR_VERSION_MONOTONIC.

Thanks,

Now that we're looking at setting the ctime and i_version separately,
I'll plan to add something that makes this explict.

Ahh - of course.  I got confused because the "raw" api is used by code
(in iversion.h) that wants to access the QUERIED bit.  Maybe having
different names would help.  Or maybe me re-familiarising myself with
the interfaces would help...

Maybe.  Or maybe we decide that if the system time goes backwards and
things break, then you get to keep both halves.
The pedant in me want to handle that properly.  The pragmatist doesn't
think it is worth it.

I'm fine with dropping that. So if the getattrs fail, we should just not
offer up pre/post attrs?

This sounds reasonable, but for one thing.

From RFC 7862:

   While Section 5.4 of [RFC5661] discusses
   per-file system attributes, it is expected that the value of
   change_attr_type will not depend on the value of "homogeneous" and
   will only change in the event of a migration.

The change_attr_type4 must be the same for all filehandles under a
particular filesystem.

If we do what you suggest though, then it's easily possible for the fs
to set STATX_ATTR_VERSION_MONOTONIC on directories but not files. If we
later want to allow nfsd to advertise a change_attr_type4, we won't be
able to rely on the STATX_ATTR_VERSION_MONOTONIC to tell us how to fill
that out.

Maybe that's ok. I suppose we could add a new field to the export
options that filesystems can set to advertise what sort of change attr
they offer?

Habit. You're probably right that this is better viewed in decimal. I'll
change it in the next iteration. We should probably also have this
display the new DIOALIGN fields as well. I'll roll that in too.

That will break clients. So no, that's not acceptable.

Yeah. This is why I mentioned that this flag would have been better
advertised via fsinfo(), had that been a thing.

One option is to just document that an fs must advertise the same flag
value for all inodes.

Alternately, we could allow the fs to set the STATX_ATTR_* flag with
per-inode granularity, and for nfsd, just add a new change_attr_type()
op to export_operations. Most filesystems would just have that return a
hardcoded value, but an nfs reexport could just pass through whatever
value it got from the server.

Not necessarily. We can document it in such a way that bumping it twice
is allowed, but not required.

My main concern with splitting them up is that we'd have to dirty the
inode twice if both the times and the i_version need updating. If the
inode gets written out in between, then we end up doing twice the I/O.
The interim on-disk metadata would be in sort of a weird state too --
the ctime would have changed but the version would still be old.

It might be worthwhile to just go ahead and continue bumping it in
file_update_time, and then we'd just attempt to bump the i_version again
afterward. The second bump will almost always be a no-op anyway.

There are 3 cases:
1/ a file/dir which advertises MONOTONIC is easy to handle.
2/ an IS_I_VERSION file/dir that does not advertise MONOTONIC will only fail
   to be MONOTONIC across unclean restart (correct?).  nfsd can
   compensate using an xattr on the root to count crashes, or just adding ctime.
3/ a non-IS_I_VERSION fs that does not advertise MONOTONIC cannot
   be compensated for by nfsd.

If we ever want nfsd to advertise MONOTONIC, then we must be able to
reject non-IS_I_VERSION filesystems that don't advertise MONOTONIC on
all files.

Maybe we need a global nfsd option which defaults to "monotoric" and
causes those files to be rejected, but can be set to "non-monotonic" and
then allows all files to be exported.

It would be nice to make it easy to run multiple nfsd instances each on a
different IP address.  Each can then have different options.  This could
also be used to reexport an NFS mount using unmodified filehandles.

Currently you need a network namespace to create a new nfsd.  I wonder
if that is a little too much of a barrier.  But maybe we could automate
the creation of working network namespaces for nfsd....

I"m probably starting to sound like a scratched record here, but this is
why I think it should be up to the filesystem to bump i_version when it
determines that it should.  It should be in a position to include the
i_version update any time that it writes the inode and so avoid a double
write.

Having that vfs/mm do so much of the work makes it hard for the
filesystem to do the right amount of work.  The common code should
provide libraries of useful code, the filesystems should call that as
appropriate. Some of our code is structured that way, some of it isn't.

Most callers of file_update_time() are inside filesystems and that is
good - they are in control.
There are 3 in mm/*.c.  Those are all in callbacks from the filesystem,
so the fs could avoid them, but only by duplicating lots of code to
avoid using the callback.  Instead these file_update_time() calls should
become more explicit calls into the filesystem telling the filesystem
what has just happened, or is about to happen.  Then the filesystem can
do the right thing, rather than having something done to it.

See also https://lwn.net/Articles/336262/ and the "midlayer mistake".

But yes, doing the bump afterwards as well is likely to be a no-op most
of the time and is probably the easy solution.  Ugly, but easy.

My current thinking is to just allow the filesystem to set
STATX_ATTR_VERSION_MONOTONIC flag on a per-inode basis, and create a new
change_attr_type() export operation and leave it up to the filesystem to
fill that out appropriately.

I think that'll give us maximum flexibility, and would also allow NFS to
pass the change attr type from the server directly through to the client
when reexporting.

If you want a internal-to-nfsd solution to this monotonic iversion
problem for file data writes, then all we need to do is take the NFS
server back to NFSv2 days where all server side data writes writes
were performed as O_DSYNC writes. The NFSv3 protocol modifications
for (unstable writes + COMMIT) to allow the NFS server to use
volatile caching is the source of all the i_version persistent
guarantees we are talking about here....

So if the NFS server uses O_DSYNC writes again, by the time the
WRITE response is sent to the client (which can now use
NFS_DATA_SYNC instead of NFS_UNSTABLE so the client can mark pages
clean immediately) both the file data and the inode metadata have
been persisted.

Further, if the nfsd runs ->commit_metadata after the write has
completed, the nfsd now has a guarantee that i_version it places in
the post-ops is both persistent and covers the data change that was
just made. Problem solved, yes?

Ideally we'd want writethrough IO operation with ->commit_metadata
then guaranteeing both completed data and metadata changes are
persistent (XFS already provides this guarantee) for efficiency,
but the point remains that STATX_ATTR_VERSION_MONOTONIC behaviour
can already be implemented by the NFS server application regardless
of when the underlying filesystem bumps i_version for data writes...

Yeah, I know writethrough can result in some workloads being a bit
slower, but NFS clients are already implemented to hide write
latency from the applications. Also, NFS servers are being built
from fast SSDs these days, so this mitigates the worst of the
latency issues that writethrough IO creates....

Cheers,

Dave.
