[git pull] more vfs bits

[git pull] more vfs bits

[Al Viro]

	Assorted stuff from this cycle.  The big ones here are multilayer
overlayfs from Miklos and beginning of sorting ->d_inode accesses out from
David.  And no, as far as I can tell David hadn't been taken over by
Malicious Entities From Beyond Spacetime^W^Wdrivers/staging - this series
is actually a useful work...  There's more stuff in that direction (nowhere
near that long, thankfully), but that's probably better dealt with after
-rc1, if not the next cycle...

	Please, pull from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git for-linus

Shortlog:
Al Viro (6):
      switch ll_lookup_finish_locks() and ll_revalidate_it_finish() to inode
      configfs: configfs_create() init callback is never NULL and it never fails
      configfs: fold create_dir() into its only caller
      configfs_add_file: fold into its sole caller
      don't bother with most of the bad_file_ops methods
      hypfs: switch to read_iter/write_iter

So I've pulled this, but quite frankly, I think I will unpull it again
unless you actually state *what* the advantages of this pointless
series of endless patches are.

There is absolutely no sane reason to use this crap, as far as I can
tell. The new "fs_inode_once()" thing is just stupid. It's named for
what it does, not *why*, and there is no hint to the filesystem as to
why it should use "fs_inode_once()" vs "fs_inode()".

Now, that was true in the "bad old days" when we just used
ACCESS_ONCE(dentry->d_inode) too, but at least in that old model we
don't have some idiotic wrapper around it.

Dammit, if we add wrapper and "helper" functions, they should *help*,
not confuse. This thing is just badly named, and there is no actual
real explanation for why it exists in the first place, nor for when to
use one or the other. There is just an endless series of patches with
pointless churn.

And no, that "explanation" in commit b717805b3c8b is not an
explanation. Why should filesystems have to know/care. Any use of
"fs_inode()" clearly does *not* specify upper/lower, so what the f*ck
is the advantage of that helper wrt just making the rule be that
"dentry->d_inode" is that unspecified thing.

Explain it, or that crap gets undone.

I'm annoyed, because shit like this that comes in at the end of the
merge window when everybody and their dog sends me random crap on the
Friday afternoon before the merge window closes is just annoying as
hell.

Yes, I work weekends too, but there is really *no* excuse for
last-minute pull requests that don't have good explanations for them.
Explanations for why they are last-minute, and explanations for why
they exist at all and why I should waste my Saturday on pulling them.

Today has been a huge waste of time for me, and reading through this
was just the last drop.

Also explain why that crap was done one file at a time?

I'm getting really tired of people trying to inflate their commit
counts with tricks like this. What was the advantage of doing the same
thing over-and-over one file at a time? It makes things more
manageable exactly *why*?

Because it wasn't.  Here's the script for your perusal.  Al cherry-picked the
output, so you won't find everything the script produces in Al's pull request.

Breaking it down into one commit per fs makes it easier to review the
individual chunks.

Use of fs_inode does not specify upper/lower; it's choice of dentry_inode() vs.
fs_inode().  And d_inode() side of that pile is what I didn't cherry-pick
from David's tree - it was too massive already.

FWIW, I probably should've collapsed the per-fs patches together, or
held them back until the next cycle; I understand why David did them
that way (less painful rebasing that stuff), but once they switch from
"try to stay sane while developing" to "into the tree it goes" mode,
they ought to have been collapsed together.  And that's something I should
have done - my fault.

Filesystems (non-layered ones) should *not* care; this fs_inode() thing is
exactly what we do right now and, unlike dentry_inode(), it is intended to
stay that way.  And yes, we could've bloody well have left it as ->d_inode;
it's no more than an annotation.  What it gives is a way to keep track of
the accesses that remain to be annotated.

Looking at that queue, it might make sense to hold back everything in that
series past "fanotify: Fix up scripted S_ISDIR/S_ISREG/S_ISLNK conversions"
for now - keep in in vfs.git for the next cycle.  My reason for pushing those
now had been no better than wanting to be rid of the trivial bits to make
life a bit easier for the next couple of months, avoiding fun on on each
conflict with every actively changing filesystem.  With the bulk of such
places annotated at once, the work would be limited to VFS proper plus
a bit of whack-a-mole in the end of cycle, pretty much consisting of annotating
the new ->d_inode instances in filesystems (all to fs_inode(), of course).
But that should've been spelled out in pull request *and* done in one
commit instead of that long tail.  Again, my apologies.

Hmm. Even I'd pull just that, quite frankly, I just think it's
*confusing* to have those badly named "helpers", that were introduced
earlier in that series.

These guys are currently all teh same thing, but even if they weren't,
the naming is not helpful, and not sane:
 - fs_inode
 - fs_inode_once
 - dentry_inode
 - dentry_inode_once

Let's walk through them:

 - dentry_inode*() is supposed to be "the inode that would be used if
the dentry was opened"

   What part of "dentry_inode()" implies "if the dentry was opened" to
you? Nothing. The name is fundamentally bad.

  And what *possible* situation could make that "_once()" version ever
be valid? None. It's bogus. It's crap. It's insane. There is no way
that it is *ever* a valid question to even ask. If the dentry is so
unstable that you can't safely look at the inode, you had damn well
better never ask "ok, what would the inode be if I opened this random
pointer"?

   So one of them is badly named, and the other one is fundamentally
not a valid operation at all, as far as I can tell.

 - fs_inode*() is supposed to be "this is the inode that the native
filesystem uses".

   So again, I think the naming is horrible, since it doesn't really
follow the normal dentry helper routine names. But I'm sure we have
other cases where we screwed that up, so whatever..

   The "_once()" naming is doubly bad, as explained elsewhere. What
possible situation merits using that helper? If it's just
revalidate(), then make it about that.

   But more importantly, this is the one where I don't see how it
could ever possibly be anything but "dentry->d_inode". I'd much rather
just leave that.

So of the four new helpers, I really don't see any of them as "good".
I think "dentry_inode()" could remain, but even there I think the name
should specify *what* it is ("d_opened_inode()"? I don't like that
name either, but at least it would try to explain what the point is,
rather than having to look up a comment above the function definition
to figure out what the point is)

The strongest argument I've seen for them existing at all was that
"markers for what has been looked at". But that's something that
belongs in a development tree, not as a series to confuse others with.

Hmm...  ..._once() variants are trivially dropped, IMO.  dentry_inode_once()
is so bloody special that it *SHOULD* stick out; we don't have any places
like that, anyway.

I'm somewhat tempted to do this:
fs_inode -> d_inode
fs_inode_once ->d_inode_rcu (it's not quite ->d_revalidate()-only, there's
a bit in autofs ->d_manage() as well)
dentry_inode -> something. d_opened_inode() might do, but I'm not sure -
still sounds a bit wrong to me.  What it's about is "the actual fs object
behind this name, maybe from upper fs, maybe showing through from underlying
layer".  It's not always opened; it's what we'd get if we opened it (and
hadn't triggered any copyups, that is).  E.g. sys_getxattr() would want to
use that, even if nobody has opened that sucker yet, etc.
dentry_inode_once -> RIP

It's still greppable ([-]>d_inode\> will do it) and IMO it's better than
fs_inode().  And yes, the churn issue remains, but IMO having a pair of
inlined helpers (d_inode(dentry) and d_inode_rcu(dentry)) in dcache.h is
not too horrible per se.

Comments?

d_inode/d_inode_rcu/[d_]inode_here(), perhaps? ;-)

Ok, those at least match our existing naming logic (ie "d_inode()"
would match what we did to "d_count()").

I'm not sure about d_inode_rcu(), for the simple reason that even when
we're doing RCU walking, most of the time we have *not* used the
ACCESS_ONCE() model, we instead end up just using the regular d_inode
and then check the sequence count.

I think.

So the ACCESS_ONCE() thing is more special than just "done under RCU".
It's more like "really special case done without any of the normal
locking _or_ any of the normal RCU checks".

That said, the overhead of using ACCESS_ONCE() is basically nil, so
it's not like we couldn't just start doing more of them, and make it
be more of a "any time we're under RCU" kind of thing.

Yeah, I think "d_backing_store_inode()" would probably be more along
the lines, but that's a mouthful. Maybe shortened to
"d_backing_inode()"?

Umm...  Works for me.  Let's do it this way, then:
	* rename those guys through the whole series
	* leave the "annotate the filesystems" bits to sit in a vfs.git
branch
	* slap trylock_super() + bugfixes I'd been doing today
(procfs and debugfs symlink removals racing with follow_link, oopsable;
double-copy in autofs dev_ioctl.c, with length not rechecked after
copying, theoretically oopsable + reasonably likely data leak) on top of queue
	* feed it through local tests and send an updated pull request later
tonight.

Looks like it survived all the local beating so far...

be standalone).  Pushed, please pull from the usual place -

How do you test?

I would like to contribute by testing...

Sounds that good to you?

As said I wanted to test with unionmount-testsuite from Git HEAD master.

But...

The README is out-of-date and...

...my python3 throws me a...

AFAICS I had reported already the README needs a refresh.

I will continue with LTP-lite testing and fio.

I switched from python-3.2 to python-3.4 from a 3rd-party PPA (see [1]
and [2]) here on Ubuntu/precise.

$ sudo add-apt-repository ppa:fkrull/deadsnakes
$ sudo apt-get update
$ sudo apt-get install python3.4 python3-deadsnakes

$ cd /usr/bin/
$ ln -sf python3.4 python3

$ python3 --version
Python 3.4.2

David, the requirement of which minimal python3 release should be
documented (README?).
Thanks.

As the mount-type changed mount_union.py needs a refresh, too.
We need to distinguish when OverlayFS is built as a module.

$ grep -i overlay /boot/config-3.19.0-9526.2-iniza-small
CONFIG_OVERLAY_FS=m

Formerly: CONFIG_OVERLAYFS_FS=m

diff --git a/mount_union.py b/mount_union.py
index 4999daa40989..e1963d6eb22a 100644
--- a/mount_union.py
+++ b/mount_union.py
@@ -27,6 +27,6 @@ def mount_union(ctx):
         workdir = upper_mntroot + "/work"
         os.mkdir(upperdir)
         os.mkdir(workdir)
-        system("mount -t overlayfs overlayfs " + union_mntroot +

         ctx.note_upper_fs(upper_mntroot, testdir)

In the end I could run unionmount-testsuite on vanilla-upstream (w/o
vfs.git#for-linus, test results will follow).

$ sudo modprobe -v overlay

$ sudo LC_ALL=C ./run --ov 2>&1 | tee
../logs/results_unionmount-testsuite_$(uname -r).txt

Have more fun!

Re: [git pull] more vfs bits

[David Howells]

You might want to remove dentry_inode_once().  I can still see it in your
vfs/for-linus branch.

It might also be worth renaming d_dentry() to d_backing_dentry() to match
d_backing_inode().

Done and re-pushed; neither sucker was ever called, so I'll skip the testing -
it's the same kernel binary.   I've pushed that to

Some functions access ->d_inode more than once.  Wouldn't that potentially
increase the number of load instructions?  Admittedly, calls to
dentry->d_inode could be replaced with inode = dentry->d_inode, then use
inode.

Sounds more reasonable than d_opened_inode().  d_actual_inode() might also
work.  d_lower_inode() might work too.

That because I wasn't thinking of it that way because it's used in a lot more

There were originally some uses of dentry_inode_once(), but I think they

That's also a poor choice.  The inode isn't even opened necessarily.  If it is
opened and you have the struct file *, you should almost certainly be using
file_inode().

Actually, that's not why I did it that way.  What I wanted was to get the
wrappers upstream in this window then I could push the individual per-fs
commits to the managers of those filesystems to go through their trees in the
next cycle.

I didn't rebase the scripted commits since I can just rerun the script.

Let me describe the problem I'm trying to solve first.

Code that accessed ->d_inode may need to look at some other dentry/inode then
the dentry it is given when the filesystem it is operating on is a layer in
some sort of union, but it sees through the filter of the top union/overlay
layer.

Take overlayfs as an example.  Regular files get dummy dentries and inodes
created in the top layer, but overlayfs has to pull a trick to go around the
VFS and repoint open files at the lower/source layer or the upper/workspace
layer rather than the overlay layer.  Access attempts outside of open files
(eg. utime) get trapped by the dummy inode and dealt with there.

Now this brings me to a particular problem: file->f_path and file->f_inode
point to either the upper layer vfsmount, dentry and inode or the lower layer
vfsmount, dentry and inode.  This means that anything that needs those
parameters does not get to see the fact that an overlay was involved.  Such
things include security LSMs, /proc, notifications, locks and leases.

So what I want to do is:

 (1) Introduce wrappers around accesses to ->d_inode.  These can be used to
     mark such accesses as being classified into two categories:

     (A) Some accesses should only consider the dentry they're given.
     	 Filesystems would fall into this category when dealing with their own
     	 dentries and inodes.

     (B) Other accesses should fall through from the dentry they're given to
     	 an underlying layer.  A lot of non-filesystem accesses, including
     	 those in the VFS side of pathwalk, fall into this category, as do
     	 accesses to external objects made by filesystems such as overlayfs
     	 and ecryptfs.

     Because there are a lot of ->d_inode calls, my intention is to classify
     them by giving them an appropriate wrapper.  Type (A) get wrapped with
     fs_inode{,_once}() and type (B) get wrapped with dentry_inode{,_once}().

     Wrapping them in this way makes it easier to find the cases that are more
     problematic.  SELinux, for example, might need to look at *both* layers
     when assessing the security label to be levied upon an overlay object.

 (2) Introduce wrappers around accesses to a given dentry where that dentry
     might not be used directly but rather fall through (similar to (1B)
     above).

 (3) Start off with wrappers that simply pass dentry or dentry->d_inode
     straight through.

 (4) Add an extra pointer into struct dentry that can be pointed at a lower
     layer - and will critically *pin* that lower layer.

     This will avoid the need for file->f_path to directly pin the dentry to
     which file->f_inode refers.  This then allows file->f_path to point to
     the top layer whilst file->f_inode points to an underlay file.

 (6) Add a DCACHE_WHITEOUT_TYPE type variant for dentries that will in the
     future be recognised by the VFS as a 'negative' type, but can be used by
     the overlay or unionmount to note a difference to an ordinary negative
     type dentry that can also be a fallthrough (at least in unionmount if
     this ever makes it).

 (7) Where feasible, replace if-statements that check the positivity or
     negativity of dentries by doing if (...->d_inode) with checks on the type
     of the dentry.

     Also, where feasible, replace S_ISxxx checks on inode type with checks of
     the dentry type field.  This cuts down on the number of accesses to the
     inode we need to do - which is good if we have to check indirectly.

     To this end, I split DCACHE_FILE_TYPE to differentiate regular and
     special types.

 (5) Make the fallthrough logic work.  You set DCACHE_FALLTHRU on a dentry and
     this tells d_dentry() and dentry_inode() to bypass the given dentry and
     use dentry->layer.lower and dentry->layer.lower->d_inode instead - but
     does not affect the operation of fs_inode().

     Note that the DCACHE_FALLTHRU flag and dentry->layer do not belong to the
     filesystem that owns the dentry on which they are set, but rather belong
     to the facility (be it overlayfs or unionmount) that is managing the
     union.


So the patch series isn't complete as it stands.  I'm trying to do the
wrapping first to reduce the number of ->d_inode accesses that need special
consideration.

I can't make ACCESS_ONCE(fs_inode(dentry)) work if fs_inode() is an inline
function.  I might be able to make it work if it's a macro.  I also don't want
to call ACCESS_ONCE() inside fs_inode().

Suggest a better name that's not too long then please.  fs_inode(d) is about
the same length as d->d_inode which means I can just script it and I don't
have to go in and reformat the code.

I did at one point have something longer for both wrappers - d_fs_own_inode()
and d_inode_or_lower().  I would quite like to have used d_inode(), but it
looks a bit too close to ->d_inode.

I want checkpatch to ultimately throw up an error if anyone adds a new
->d_inode access.  They can be instructed to use either fs_inode() or
dentry_inode().

Further, leaving dentry->d_inode as is all over the place makes it much harder
to find the stuff that needs to be considered carefully - there are over 2000
instances of ->d_inode in the code and grepping to find them is annoying with
so many false positives available.

However, a lot of the ->d_inode accesses can safely be scripted out of the
way, vastly cutting down the output of grep.

.. and this is the one that makes no sense to me.

It's the common case, and I don't see how it *possibly* adds any
value. The "I want the inode of this dentry" is traditionally done as
"dentry->d_inode".

What is the *upside* of the wrapper?

Again, if they actually want something *else* than the "native inode",
then at that point a wrapper makes sense.

If you actually want to document that "this use wants the underlying
inode", then go wild. But that is *different* from all the common uses
inside random filesystems that just want "what's the inode of this
dentry".

IOW, my argument is that I cannot see *any* possible reason to wrap
the normal "give me the inode associated with this dentry".

I *can* see a reason to wrap - and document - the cases that are *not*
that kind of simple thing. I *can* see the reason for saying "give me
the inode of the lower layer", or "give me the inode, or NULL if it's
a whiteout entry".

But it's just that empty "fs_inode()" wrapper itself that I just don't
see the point of.

Every single low-level filesystem that does all the actual core
lookup/mkdir/create/whatever operations care about the native inode.
You seem to even kind of acknowledge that in the naming: "fs_inode()".
And my argument is that there is never any possible reason why that
would ever be anything but "dentry->d_inode".

So the wrapper doesn't actually help anything, and it *does* obfuscate
things. It makes people go "whats' the difference between "fs_inode()"
and "fs_inode_once()". It quite possible makes people think it's an
expensive operation. Who knows. It seems pointless.

Right. And a helper/wrapper makes sense for those cases, and actually
clarifies that "this particular code knows and cares about whiteout
entries".

I'm not arguing against those kinds of wrappers that actually
_clarify_ things. I'm arguing against random wrappers that don't, and
that really fundamentally seem like they cannot possibly ever have any
other valid value.

A low-level filesystem may have a real inode associated with a
whiteout dentry, it could be a device inode with a zero major number
or some other special inode (or it might not be an inode at alln - it
could easily also be just a directory entry type). Such a filesystem
would clearly care about the inode. and would actually really care
about "dentry->d_inode".

And I actually think that having "dentry->d_inode" is *clearer* than
"fs_ionode(dentry)". It's clear that that is a naked native access.
It's not some hidden abstracted case. That's *the* inode associated
with the dentry.

.. and this is again the kind of wrapper I think is *good*. It's
abstracting some real issue.

I don't object at all to abstracting out "ok, a dentry is negative if
it has a NULL inode, or if it is marked as a whiteout entry". I think
that writing

        if (d_negative(dentry)) ...

is more readable than

        if (!dentry->d_inode ||  (dentry->d_flags & DCACHE_WHITEOUT)) ..

or variations of that (I guess it's "IS_WHITEOUT(dentry->d_inode)" right now).

So I'm not against helpers that do something meaningful.

And there are downsides to arbitrary random wrappers/helpers. Churn.
Harder to see what the code actually *does*. Bad naming (dentry
operations are generally called "d_xyz()" or "dentry_xyz()").  Does it
do soemthign else? Are there rules for calling this? All the mental
rules you have to have, and that *change* just because you change the
syntax.

Oh, I see *why* you did it, given that you wanted a wrapper.

But I also see this very much as an example of "the wrapper is
actually causing  more problems than it's solving". The fact that the
first wrapper exists now means that you have to use *another* wrapper.

And dammit, it's not *helping*.

Now, if it was something like "ok, the revalidate() call is very very
special for a low-level filesystem, in that the filesystem cannot
trust the inode pointer, so we have a special
"d_revalidate_inode(dentry) wrapper that does ACCESS_ONCE()", then
such a wrapper would actually be *documentation*, and would kind of
show something real ("revalidate is special").

See what I'm trying to say? At that point - even if the wrapper
doesn't *do* anything - it at least documents some rule, and migth be
worth it for that reason.

But what does "fs_inode_once()" document? Nothing. It's just an
artifact of you having introduced a wrapper and done a
search-and-replace. So now you have the extra abstraction of a
wrapper, with all the disadvantages of abstractions, and none of the
advantages that abstraction is supposed to actually bring us.

So I didn't check, but I *think* the only valid use for the
ACCESS_ONCE() on ->d_inode is for revalidate, which is kind of special
in that we call it without locks held. So *if* that is true, then
maybe "d_revalidate_inode()" would be a reasonable name. But again, I
didn't check that semantic rule, so maybe it doesn't work.

And yes, I'm annoyed, because I really hate the timing of this pull
request. So it's not just about the wrapper, it's about when/how this
all reached me.

AFAICS, having yet-to-be-annotated cases stick out...

BTW, the goal this series is aiming at probably ought to be spelled out
more clearly: there's a bunch of stacking-related stuff (overlayfs and
ecryptfs in the tree, at least unionmount and aufs outside) that could
benefit from having the notion "this dentry covers that stack of
dentries from underlying fs layers" supported sanely by VFS, rather
than having it open-coded in one way or another.  And every place like
that ends up in incestous relationship with VFS; it was annoying while
it had been just ecryptfs, but it's getting worse now.  Moreover, the
details of behaviour overlayfs ends up having to rely upon are both
potentially brittle *and* leaving quite a few things not working properly
(starting with /proc/*/fd/* readlink, etc.)  The goal behind
all that massage is to have that notion (stacking) understood by VFS.

And no, it's not related to the question of annotating ->d_inode accesses -
just something that wasn't quite obvious from David's description.
IMO it's worth spelling out somewhere in this thread...

      9p: make sure ->lookup() adds fid to the right dentry
      9p: if v9fs_fid_lookup() gets to asking server, it'd better have hashed dentry
      cache the value of file_inode() in struct file
      fix nommu breakage in shmem.c
      constify path_get/path_put and fs_struct.c stuff
