Hi folks.
I am observed kernel panic after update to git tag 5.2-rc2.
This crash happens at memory pressing when swap being used.

Unfortunately in journalctl saved only this:

The problem still occurs at 5.2-rc3.
Unfortunately hard reproducible does not allow to make bisect.
Any ideas what is wrong?

I can say with 100% certainty that kernel tag 5.1 is not affected by this bug.

Say anything about 5.2 rc1 is very difficult because occurs another
problem due to which all file systems are switched to read only mode.

And I am sure that since 5.2 rc2 this issue is begin occurring.

I also able recorded much more kernel logs with netconsole and option
memblock=debug. (attached as file here)

Please help me.

That's commit "tcp: fix retrans timestamp on passive Fast Open" which is
almost certainly not the culprit.

You told bisect that 5.2-rc1 is good, but it probably isn't.
What you probably need to do is:
git bisect good v5.1
git bisect bad v5.2-rc2

The presence of the other ext4 bug complicates the bisect, however.
According to tytso in the thread you linked, it should be fixed by
commit 0a944e8a6c66, while the bug was introduced by commit
345c0dbf3a30. So in each step of bisect, before building the kernel, you
should cherry-pick the fix if the bug is there:

git merge-base --is-ancestor 345c0dbf3a30 HEAD && git cherry-pick 0a944e8a6c66

Also in case you see a completely different problem in some bisect step, try
'git bisect skip' instead of guessing if it's good or bad.
Hopefully that will lead to a better result.

The VM_BUG_ON_PAGE has been touched in 5.2-rc1 by commit
5fd4ca2d84b2 ("mm: page cache: store only head pages in i_pages")

Yes, I seen also content of this commit.
And it looks like madness.
But I can proving that my bisect are properly created.
Here I saved all dmesg output from all bisecting steps:
https://mega.nz/#F!00wFHACA!nmaLgkkbrlt46DteERjl7Q
And only one of them ended without crash message "kernel BUG at
mm/swap_state.c:170!"
This is step5 with commit 3d21b6525cae.

I tried to cause kernel panic several times when kenel compiled from
commit 3d21b6525cae would be launched and all my attempts was be
unsuccessful.

So I can say that commit 3d21b6525cae is enough stable for me and I
now sitting on it.

Oh, thanks for advise. But I am used another solution.
(I applied the patch every time when bisect move to new step)

If you take a look all my dmesg logs you can sure that all bad steps
ended with crash "kernel BUG at mm/swap_state.c:170!".

And yes, I look again at commit cd736d8b67fb still don't understand
how it can broke my system.

Yes, this is exactly right commit.
But when I did bisect I am found yet another problem.
When hit memory limit and starting paging the virtual machine in KVM is hanged.
If after it I reboot computer then the system will completely hang.
All this commits I marked as skip in my bisecting.
And the backtrace in kernel log looks like as below:

 The third problem I noticed a long time ago. Symptomes: applications
can use only half of the swap partition. I have a swap partition size
RAM * 2. The applications start crashing when the swap partition is
used more than half. And this is not OOM.
For example for testing each commit I completely filled  RAM, and
after sure that system is not hanged I launched compiling next bisect
iteration. And here happens crashes of gcc if swap is used over 32GB.
(Full swap size is 64GB)

Commands above lead to cyclic bisecting on one commit. So I used `git
stash` and `git stash pop` for applying ext4 patch.

Hey folks.
Excuse me, is anybody read my previous message?
5.2-rc7 is still affected by this issue [the logs in file
dmesg-5.2rc7-0.1.tar.xz] and I worry that stable 5.2 would be released
with this bug because there is almost no time left and I didn't see
the attention to this problem.
I confirm that reverting commit 5fd4ca2d84b2 on top of the rc7 tag is
help fix it [the logs in file dmesg-5.2rc7-0.2.tar.xz].
I am still awaiting any feedback here.
Thanks.

Yeah, I guess revert of 5fd4ca2d84b2 at this point is probably the best we
can do. Let's CC Linus, Andrew, and Greg (Linus is travelling AFAIK so I'm
not sure whether Greg won't do release for him).

I'm back home now, although possibly jetlagged.

The revert looks trivial (a conflict due to find_get_entries_tag()
having been removed in the meantime), and I guess that's the right
thing to do right now.

Matthew, comments?

I am trying to reproduce this bug.  Can you give me some information
about your test case?

It not easy, but I try to explain:

1. I have the system with 32Gb RAM, 64GB swap and after boot, I always
launch follow applications:
    a. Google Chrome dev channel
        Note: here you should have 3 windows full of tabs on my
monitor 118 tabs in each window.
        Don't worry modern Chrome browser is wise and load tabs only on demand.
        We will use this feature later (on the last step).
    b. Firefox Nightly ASAN this build with enabled address sanitizer.
    c. Virtual Machine Manager (virt-manager) and start a virtual
machine with Windows 10 (2048 MiB RAM allocated)
    d. Evolution
    e. Steam client
    f. Telegram client
    g. DeadBeef music player

After all launched applications 15GB RAM should be allocated.

2. This step the most difficult, because we should by using Firefox
allocated 27-28GB RAM.
    I use the infinite scroll on sites Facebook, VK, Pinterest, Tumblr
and open many tabs in Firefox as I could.
    Note: our goal is 27-28GB allocated RAM in the system.

3. When we hit our goal in the second step now go to Google Chrome and
click as fast as you can on all unloaded tabs.
    As usual, after 60 tabs this issue usually happens. 100%
reproducible for me.

Of course, I tried to simplify my workflow case by using stress-ng but
without success.

I hope it will help to make autotests.

Yes.  This is quite complex.  Is the transparent huge page enabled in
your system?  You can check the output of

$ cat /sys/kernel/mm/transparent_hugepage/enabled

And, whether is the swap device you use a SSD or NVMe disk (not HDD)?

Thanks!  I have found another (easier way) to reproduce the panic.
Could you try the below patch on top of v5.2-rc2?  It can fix the panic
for me.

Thanks! Amazing work! The patch fixes the issue completely. The system
worked at a high load of 16 hours without failures.

But still seems to me that page cache is being too actively crowded
out with a lack of memory. Since, in addition to the top speed SSD on
which the swap is located, there is also the slow HDD in the system
that just starts to rustle continuously when swap being used. It would
seem better to push some of the RAM onto a fast SSD into the swap
partition than to leave the slow HDD without a cache.

But I am afraid it will be difficult to implement such an algorithm
that analyzes the waiting time for the file I/O and waiting for paging
(memory) and decides to leave parts in memory where the waiting time
is more higher it would be more efficient for systems with several
drives with access speeds can vary greatly. By waiting time I mean
waiting time reading/writing to storage multiplied on the count of
hits. Thus, we will not just keep in memory the most popular parts of
the memory/disk, but also those parts of which read/write where was
most costly.

Thanks a lot for your help!

Hi, Matthew and Kirill,

I think we can fold this fix patch into your original patch and try
again.

Yes.  This is a valid problem.  I remember Johannes has a solution long
ago, but I don't know why he give up that.  Some information can be
found in the following URL.

I tried something along these lines (though I think I messed up the offset
calculation which is why it wasn't working for me).  My other concern
was with the case where SWAPFILE_CLUSTER was less than HPAGE_PMD_NR.
Don't we need to drop the lock and look up a new swap_cache if offset >=
SWAPFILE_CLUSTER?

In swapfile.c, there is

#ifdef CONFIG_THP_SWAP
#define SWAPFILE_CLUSTER	HPAGE_PMD_NR
...
#else
#define SWAPFILE_CLUSTER	256
...
#endif

So, if a THP is in swap cache, then SWAPFILE_CLUSTER equals
HPAGE_PMD_NR.


And there is one swap address space for each 64M swap space.  So one THP
will be in one swap address space.

In swap.h, there is

/* One swap address space for each 64M swap space */
#define SWAP_ADDRESS_SPACE_SHIFT	14
#define SWAP_ADDRESS_SPACE_PAGES	(1 << SWAP_ADDRESS_SPACE_SHIFT)
