support splice reads on seq_file based procfs files v2

support splice reads on seq_file based procfs files v2

[Christoph Hellwig]

Hi Al,

Greg reported a problem due to the fact that Android tests use procfs
files to test splice, which stopped working with 5.10-rc1.  This series
adds read_iter support for seq_file, and uses those for various seq_files
in procfs to restore splice read support.

Chances since v1:
 - only switch a subset of proc files to use seq_read_iter

[PATCH 1/6] seq_file: add seq_read_iter

[Christoph Hellwig]

iov_iter based variant for reading a seq_file.  seq_read is
reimplemented on top of the iter variant.

Ack.

Al, do you want me to take these directly - we'll need this to avoid
the regression in 5.10?  Or do you have other things pending and I'll
see them in a pull request.

This is actually broken from generic_file_splice_read() POV; if you've
already emitted something, you will end up with more data spewed into
pipe than you report to caller.  You want something similar to
copy_to_iter_full() here, with iterator _not_ advanced in case of
failure.  The first call is not an issue (you have no data copied
yet, so you'll end up with -EFAULT, aka "discard everything you've
put there and return -EAGAIN"), but the second really is a problem.

BTW, other ->read_iter() instances might need to be careful with that
pattern as well; drivers/gpu/drm/drm_dp_aux_dev.c:auxdev_read_iter()
would appear to have the same problem.

<greps some more>
                if (unlikely(iov_iter_is_pipe(iter))) {
                        void *addr = kmap_atomic(page);

                        written = copy_to_iter(addr, copy, iter);
                        kunmap_atomic(addr);   
                } else
in fs/cifs/file.c looks... interesting, considering the fact that
copy_to_iter() for pipe destination might very well have to do
allocations.  With GFP_USER.  Under kmap_atomic()...

Note that we have this:
static inline int copy_linear_skb(struct sk_buff *skb, int len, int off,
                                  struct iov_iter *to)
{
        int n;

        n = copy_to_iter(skb->data + off, len, to);
        if (n == len)
                return 0;

        iov_iter_revert(to, n);
        return -EFAULT;
}
i.e. the same "do not advance on short copy" kind of thing.

AFAICS, not all callers want that semantics, but I think it's worth
a new primitive.  I'm not saying it should be a prereq for your
series, but either that or an explicit iov_iter_revert() is needed.

Seeing that it already went into mainline, it needs a followup fix.
And since it's not -stable fodder (AFAICS), I'd rather go with
adding a new primitive...

Any objections to the following?

Fix seq_read_iter() behaviour on full pipe

generic_file_splice_read() will purge what we'd left in pipe in case
of error; it will *not* do so in case of short write, so we must make
sure that reported amount of data stored by ->read_iter() matches the
reality.

It's not a rare situation (and we already have it open-coded in at least
one place), so let's introduce a new primitive - copy_to_iter_full().
Similar to copy_from_iter_full(), it returns true if we had been able
to copy everything we'd been asked to and false otherwise.  Iterator
is advanced only on success.

Well, I don't _object_, but I find it ugly.

And I think both the old and the "fixed" code is wrong when an EFAULT
happens in the middle.

Yes, we can just return EFAULT. But for read() and write() we really
try to do the proper partial returns in other places, why not here?

IOW, why isn't the proper fix just something like this:

which should get the "efault in the middle" case roughly right (ie the
usual "exact byte alignment and page crosser" caveats apply).

Look at the loop after that one, specifically the "it doesn't fit,
allocate a bigger one" part:
                kvfree(m->buf);
                m->count = 0;
                m->buf = seq_buf_alloc(m->size <<= 1);
It really depends upon having m->buf empty at the beginning of
the loop.  Your variant will lose the data, unless we copy the
"old" part of buffer (from before the ->show()) into the
larger one.

That can be done, but I would rather go with
		n = copy_to_iter(m->buf + m->from, m->count, iter);
		m->count -= n;
		m->from += n;
                copied += n;
                if (!size)
                        goto Done;
		if (m->count)
			goto Efault;
if we do it that way.  Let me see if I can cook something
reasonable along those lines...

copy_to_iter() returns the amount it has actually copied, that's all;
the cause of that bug is not the primitives used, it's the rules for
->read_iter().  The rules are actually fairly simple - "->read_iter()
should not report less data than it has actually left there".  For read(2)
it's a matter of QoI - if we hit an unmapped page, POSIX pretty much says
that all bets are off; read(fd, unmapped - 5, 8) might copy 5 bytes and
return 4.  It is allowed (and read(2) on those files used to do just that),
but it's nicer not to do so.  For generic_file_splice_read(), OTOH, it's
a bug - we end up with stray data spewed into pipe.  So converting
to ->read_iter() needs some care.  Probably something along those
lines should go into D/f/porting...

This patch in -next (6a9f696d1627bacc91d1cebcfb177f474484e8ba) breaks
WSL2's interoperability feature, where Windows paths automatically get
added to PATH on start up so that Windows binaries can be accessed from
within Linux (such as clip.exe to pipe output to the clipboard). Before,
I would see a bunch of Linux + Windows folders in $PATH but after, I
only see the Linux folders (I can give you the actual PATH value if you
care but it is really long).

I am not at all familiar with the semantics of this patch or how
Microsoft would be using it to inject folders into PATH (they have some
documentation on it here:
https://docs.microsoft.com/en-us/windows/wsl/interop) and I am not sure
how to go about figuring that out to see why this patch breaks something
(unless you have an idea). I have added the Hyper-V maintainers and list
to CC in case they know someone who could help.

Cheers,
Nathan

Out of curiosity: could you slap WARN_ON(!iov_iter_count(iter)); right in
the beginning of seq_read_iter() and see if that triggers?

Sure thing, it does trigger.

*blink*

	Lovely...  For one thing, it did *not* go through
proc_reg_read_iter().  For another, it has hit proc_reg_read() with
zero length, which must've been an iovec with zero ->iov_len in
readv(2) arguments.  I wonder if we should use that kind of
pathology (readv() with zero-length segment in the middle of
iovec array) for regression tests...

	OK...  First of all, since that kind of crap can happen,
let's do this (incremental to be folded); then (and that's
a separate patch) we ought to switch the proc_ops with ->proc_read
equal to seq_read to ->proc_read_iter = seq_read_iter, so that
those guys would not mess with seq_read() wrapper at all.

	Finally, is there any point having do_loop_readv_writev()
call any methods for zero-length segments?

	In any case, the following should be folded into
"fix return values of seq_read_iter()"; could you check if that
fixes the problem you are seeing?

Unfortunately that patch does not solve my issue. Is there any other
debugging I should add?

Hmm...  I wonder which file it is; how about
		if (WARN_ON(!iovec.iov_len))
			printk(KERN_ERR "odd readv on %pd4\n", file);
in the loop in fs/read_write.c:do_loop_readv_writev()?

Assuming you mean this?

Assuming so, I have attached the output both with and without the

Cute...  FWIW, on #origin + that commit with fix folded in I don't

OK, so let's do this: fix in seq_read_iter() + in do_loop_readv_writev()
(on entry) the following (racy as hell, but will do for debugging):

	bool weird = false;

	if (unlikely(memcmp(file->f_path.dentry->d_name.name, "mountinfo", 10))) {
		int i;

		for (i = 0; i < iter->nr_segs; i++)
			if (!iter->iov[i].iov_len)
				weird = true;
		if (weird) {
			printk(KERN_ERR "[%s]: weird readv on %p4D (%ld) ",
				current->comm, filp, (long)filp->f_pos);
			for (i = 0; i < iter->nr_segs; i++)
				printk(KERN_CONT "%c%zd", i ? ':' : '<',
					iter->iov[i].iov_len);
			printk(KERN_CONT "> ");
		}
	}
and in the end (just before return)
	if (weird)
		printk(KERN_CONT "-> %zd\n", ret);

Preferably along with the results of cat /proc/<whatever it is>/mountinfo both
on that and on the working kernel...

FWIW, just to make sure:
	1) does reverting just that commit recover the desired behaviour?
	2) could you verify that your latest tests had been done with
the incremental I'd posted (shifting the if (....) goto Done; out of the if
body)?
	3) does the build with that commit reverted produce any warnings
related to mountinfo?
	4) your posted log with WARN_ON unfortunately starts *after*
the mountinfo accesses; could you check which process had been doing those?
The Comm: ... part in there, that is.
	5) in the "I don't believe that could happen, but let's make sure"
department: turn the
        /* m->count is positive and there's space left in iter */
comment in seq_read_iter() into an outright
	BUG_ON(!m->count || !iov_iter_count(iter));

Side note: if this ends up working, can you add a lot of comments
about this thing (both in the code and the commit message)? It
confused both Christoph and me, and clearly you were stumped too.
That's not a great sign.

OK...  Now that I have a reproducer[1], I think I've sorted it out.
And yes, it had been too subtle for its own good ;-/

[1] I still wonder what the hell in the userland has come up with the
idea of reading through a file with readv(), each time with 2-element
iovec array, the first element covering 0 bytes and the second one - 1024.
AFAICS, nothing is systemd git appears to be _that_ weird...  Makes for
a useful testcase, though...

Anyway, could you test this replacement?

OK... a variant with (hopefully) better comments and cleaned up
logics in the second loop (
                if (seq_has_overflowed(m) || err) {
                        m->count = offs;
                        if (likely(err <= 0))
                                break;
                }
replaced with
                if (err > 0) {          // ->show() says "skip it"
                        m->count = offs;
                } else if (err || seq_has_overflowed(m)) {
                        m->count = offs;
                        break;
                }
) follows.  I'm quite certain that it is an equivalent transformation
(seq_has_overflowed() has no side effects) and IMO it's slightly
more readable that way.  Survives local beating; could you check if
it's still OK with your testcase?  Equivalent transformation or not,
I'd rather not slap anyone's Tested-by: on a modified variant of
patch...

BTW, is that call of readv() really coming from init?  And if it
is, what version of init are you using?

Still good.

I believe that it is but since this is WSL2, I believe that /init is a
proprietary Microsoft implementation, rather than systemd or another
init system:

https://wiki.ubuntu.com/WSL#Keeping_Ubuntu_Updated_in_WSL

So I am not sure how possible it is to see exactly what is going on or
getting it improved.

Oh, well...  Anyway, as a regression test it's interesting:

#include <sys/uio.h>
#include <unistd.h>
#include <stdio.h>
#include <errno.h>
main()
{
	static char s[1024];
	static struct iovec v[2] = {{NULL, 0}, {s, 1024}};

	for(;;) {
		ssize_t n = readv(0, v, 2), m, w;

		if (n < 0) {
			perror("readv");
			return -1;
		}
		if (!n)
			return 0;
		for (m = 0; m < n; m += w) {
			w = write(1, s + m, n - m);
			if (w < 0)
				perror("write");
		}
	}
}

which ought to copy stdin to stdout; with this bug it would (on sufficiently
large seq_file-based files) fail with "readv: Bad address" (-EFAULT, that is).

Shouldn't this go to Linus before v5.10 is released?

So by now I'm a bit worried about this series, because the early fixes
caused more problems than the current state.

So considering the timing and Al having been spotty, I think this is
post-5.10 and marked for stable.

Al, I'm willing to be convinced otherwise, but you need to respond..

Said that, it does appear to survive all beating, and it does fix
a regression introduced in this cycle, so, provided that amount of
comments in there is OK with you...

If you want some sort of "do these really work" validation, these have
been running for a while now in the android 5.10-rc kernels just fine,
as I cherry-picked the patches there to get past their testing issues.

But if you want to wait until after 5.10 is out, that's fine with me
too, it's up to Al.

thanks,

Ok, considering Greg's note, I've pulled it. It's early in the last
week, if something comes up we can still fix it.

That said, considering that I think the only use-case was that odd
/proc splice use, and the really special WSL2 thing, and both of those
are verified, it does sound safe to pull.

Famous last words...

Al, since you're around, would you mind looking at the two
DCACHE_DONTCACHE patches too? Honestly, since they seem to be an issue
only for DAX, and only for DAX policy changes, I don't consider them
critical for 5.10, but they've been around for a while now.

Umm...  I've got
fs: Handle I_DONTCACHE in iput_final() instead of generic_drop_inode()
and
fs: Kill DCACHE_DONTCACHE dentry even if DCACHE_REFERENCED is set
in "to apply" pile; if that's what you are talking about, I don't
think they are anywhere critical enough for 5.10-final, but I might
be missing something...

Al, still buried under piles of email ;-/

Yup, those were the ones.

No, I agree, no hurry with them. I just wanted to make sure you're
aware of them.
