A file is opened for read-only, opened read-write (resulting in a copy up)
and modified.  The data read back from the the read-only fd will be stale
in this case (the read-only file descriptor still refers to the lower,
unmodified file).

This patchset fixes issues related to this corner case.

The VFS impact is minimal and performance in the non-corner cases shouldn't
suffer.

passed my tests.
I now run all my tests (including unionmount-testsuite) on a setup of
overlayfs over xfs with reflink:
- xfstests - from my github overlayfs-devel branch
  -g quick and overlay/*
  including new test 016 to check ro/rw fd data inconsistencies
- pjdfstest - from my github overlayfs-devel branch
  including acl/xattr tests
- unionmount-testsuite - from my github overlayfs-devel branch
  without recycling (--ov), with mount recycle -(-ov=0) and with mount
recycle and
  layers (--ov=10)

Almost all of the time overlayfs just wants to let underlying filesystems
handle file operations on regular files.

There is a rare corner case, namely when a file residing a read-only
(lower) layer is:

 - opened for O_RDONLY
 - opened for O_WRONLY
 - contents modified
 - contents read back though O_RDONLY fd

Currently overlayfs gives inconsistent result in this case, since the
O_RDONLY file refers to the lower, unmodified file, even after the copy up
has happened.

This happens very rarely, so

a) we want the normal cases (when no copy up happens) still go as fast as
   possible;

b) we can let the corner case go slow.

The proposed solution is to allow overlayfs to intercept file operations if
it wants (O_RDONLY open of file on lower layer), but still let the file be
owned by the underlying layer.  This means everything in filp, including
the private_data, is controlled by the underlying layer (as it has been
until now) with the exception of f_op, which comes from overlayfs.

This patch doesn't change the actual behavior, it just adds the vfs change
necessary and then unconditionally sets the f_op back to the underlying
file's ops.

For non-overlayfs, this doesn't change anything.

Already exported to modules, just needs to move declaration from
"fs/internal.h" to <linux/fs.h>.

This will be used by overlayfs to clone a read-only file that has been
copied up after being opened.  The clone will refer to the copied-up uppper
file instead of the original, lower file.

A corner case of a corner case is when

 - file opened for O_RDONLY
 - which is then memory mapped SHARED
 - file opened for O_WRONLY
 - contents modified
 - contents read back though the shared mapping

Unfortunately it looks very difficult to do anything about the established
shared map after the file is copied up.  Instead when a read-only file is
mapped shared overlayfs copies up the file before actually doing the map.
This may result in unnecessary copy-ups (but so may copy-up on open(O_RDWR)
for exampe).

We can revisit this later if it turns out to be a performance problem in
real life.

Overlayfs needs to intercept a few file operations in order to properly
handle the following corner case:

 - file X is in overlayfs;

 - X resides on a lower (read-only) layer
	the lower file is L;

 - X is opened with O_RDONLY ->
	L is opened -> 'rofd';

 - X is opened with O_WRONLY ->
	this results in L being copied up to the upper layer file U
	U is opened -> 'rwfd';

 - write to 'rwfd' modifying U;

 - read from 'rofd' gets data from unmodified L;

While this is a rare occurrence, it has been known to cause problems.  To
prevent such inconsistencies, allow intercepting read operations and fix
them up in the unlikely case that it's needed.

This patch adds an ovl_fops structure that is going to contain the pieces
necessary for intercepting file operations:

 a) a new file_operations structure, based on the original but changing
    those operations that need to be intercepted;

 b) a pointer to the origin f_op.  Intercepted operations will normally
    just call the original, unless the file was copied up;

 c) a hash table entry to hook this up for reuse in subsequent opens.

The hash table is small (32 buckets) since there will only be a few
different file operations used (basically the number of different
filesystems used as lower layer of overlay).  The key to the has table is
the original fops pointer.

Insertion is done under a global mutex.  There will only be one insertion
event for each unique underlying file_operations structure, so this is
going to be rare.

The hash table is accessed using rcu, so this will add minimal overhead to
opens.  The override fops are removed only at module exit time, so we don't
even have to be worry about read-side rcu locking.

There are a few assumption this scheme makes about file operation
structures supplied by filesystems:

 1) the lifetime of the structures is equal to the lifetime of the
    filesystem module; ensure this by holding a ref to the
    sb->s_type->owner (normal filesystems don't fill in f_ops->owner).
    This means that once a filesystem has been used as lower layer of
    overlayfs its module cannot be removed until the overlay module itself
    is removed.  I don't believe this will be a problem.

 2) Filesystems should not make use of f_op in any way except possibly
    replacing it in ->open.  Overlayfs itself breaks this assumption, but
    recursion is handled by ->d_real so this is not an issue.  Add a
    ->magic field to the override fops structure to verify that the
    filesystem didn't mess with file->f_op.

Suggestion:
if (!ofop) goto out_unlock;
and rid of all this nested chunk

It could also be handled in vfs helpers.
Since these ops all start with establishing that src and dest are on
the same sb,
then the cost of copy up of src is the cost of clone_file_range from
lower to upper,
so it is probably worth to copy up src and leave those fops alone.

Not sure I understand.  Why should we copy up src?  Copy up is the
problem not the solution.

Maybe the idea is ill conceived, but the reasoning is:
To avoid the corner case of cloning from a stale lower src,
call d_real() in vfs helpers to always copy up src before cloning from it
and pass the correct file onwards.

It would have been crazy if we suggested the same for read_iter(),
so why it may make sense for clone?
because once you got that far into the vfs_clone_range() helper,
with src from lower and dst from upper, it means they are on the same sb
that supports clone, so it is likely that copy up is going to use clone and
be relatively cheap.

Pretty twisted. I agree... and not sure if this logic holds for copy_range as
well. Anyway, that's what I meant.

Amir.

Which correct file?  src is still the wrong one after calling d_real.
We need to clone-open src, just like we do in ovl_read_iter to get the
correct file.  But then what's the use of copying it up beforehand?

We could move the whole logic into the vfs, but I don't really see the point.

I left these ops alone because there is some confusion in there about
getting the f_op from the source or the destination file.  And while
it doesn't matter normally (all regular files have the same f_op,
regardless of open flags)  it does matter for overlayfs intercept,
because overriding fops in the the dest file would mean additional
complexity and  resources).  That could easily be fixed in the vfs:
calling src->f_ops->foo works equally well, but I simply didn't want
to bother with this.  We can return to it later.

Thanks,
Miklos

Yes, I saw that. Shouldn't be a problem to always use src->f_ops-> IMO.

Could you please push this work to a topic branch to make it easier for me to
pull and test?

Here is a relevant use case (creating several clones),
although not directly related to ro/rw inconsistency, which
justified putting the logic in vfs.

X is a file in lower
lower is different fs then upper
upper supports clone/dedup/copy_range

for i in `seq 1 100`; do cp --reflink=auto X X${i}; done

With current code the src and destination files are on the same
mount (test in  ioctl_file_clone), but not on the same sb (test in
vfs_clone_file_range), so cp will fall back to 100 expensive data copies.

*If* instead we d_real() and clone-open src in start of vfs_clone_file_range
*after* verifying the dest file ops support clone, then we will get only one
expensive copy up and 100 cheap clones, so its a big win.

And for the case of src and dst inodes already on the same sb, we can
skip d_real() to avoid possible unneeded copy up, although a clone up
is going to be cheap anyway.

The so called worst case is that this was a one time clone (to X1),
but the cost in this case is not huge - 1 data copy up of X and 1 clone
X->X1 instead of just 1 data copy X->X1, so the difference is negligible.

Now it's true that this is heuristic, but arguably a good one.

Amir.

Good timing :-)
I just started working on an xfstest this morning to bring this corner
case into attention.
Once I get the xfs_io commands in order, you could use them for a
shorter commit message.
Unless you like it that way...

Well, there is a bug/feature is xfs_io that puts it in a spin when an
open command is
used from command line, so I will need to fix that before sumbitting
the xfstest, but for
documentation purpose, you can use the following command in place of rorw-map:

$ xfs_io -r -c "mmap -r 0 4" -c "open foo" -c "pwrite -S 0x61 0 4" -c
"mread -v 0 4" foo |tail -n 1
00000000:  62 61 62 61  baba

Naturally, 'baba' is bad. 'aaaa' is good.

Or maybe it was meant to be used this way, which does not blow up:

mread -v 0 4

Fsync is really an inode operation (AFAICS) so a doing it on a O_RDONLY
file descriptor should flush any data written through an O_WRONLY file
descriptor for example.

To make this work correctly in case the file is copied up after being
opened for read intercept the fsync fop, similarly to read_iter and mmap.
