Hello all,

We are getting processes stuck with /proc/pid/stack listing the following:

For some reason io_schedule is not coming back, so shrinker_rwsem never 
gets an up_read. When this happens, other processes like libvirt get stuck 
trying to start VMs with the /proc/pid/stack of libvirtd looking like so, 
while register_shrinker waits for shrinker_rwsem to be released:

[<ffffffffac7538d3>] call_rwsem_down_write_failed+0x13/0x20
[<ffffffffac1cb985>] register_shrinker+0x45/0xa0

[<ffffffffac80012c>] entry_SYSCALL64_slow_path+0x25/0x25
[<ffffffffffffffff>] 0xffffffffffffffff


I seem to be able to reproduce this somewhat reliably, it will likely be 
stuck by tomorrow morning. Since it does seem to take a day to hang, I was 
hoping to avoid a bisect and see if anyone has seen this behavior or knows 
it to be fixed in 4.15-rc.

Note that we are using zram as our only swap device, but at the time that 
it shrink_slab() failed to return, there was plenty of memory available 
and no swap was in use.

The machine is generally responsive, but `sync` will hang forever and our 
only way out is `echo b > /proc/sysrq-trigger`.

Please suggest any additional information you might need for testing, and 
I am happy to try patches.

Thank you for your help!

Is this a permanent state or does the holder eventually releases the
lock? It smells like somebody hasn't unlocked the shmem page. Tracking
those is a major PITA... :/

Do you remember the last good kernel?

Maybe something related with f80207727aac ("mm/memory.c: release locked
page in do_swap_page()")

Commit f80207727aaca3aa ("mm/memory.c: release locked page in do_swap_page()")
was added in v4.15-rc9, and commit 0bcac06f27d75285 ("mm, swap: skip swapcache
for swapin of synchronous device") was added in v4.15-rc1. Since commit
0bcac06f27d75285 was not backported to 4.14-stable kernel, it is unlikely
unless Eric explicitly backported that commit.

Perpetual. It's been locked for a couple days now on two different 
servers, both running the same 4.14.15 build.


> Do you remember the last good kernel?

We were stable on 4.1.y for a long time. The only reason we are updating 
is because of the Spectre/Meltdown issues.

I can probably test with 4.9 and let you know if we have the same problem. 
If you have any ideas on creating an easy way to reproduce the problem, 
then I can bisect---but bisecting one day at a time will take a long time, 
and could be prone to bugs which I would like to avoid on this production 
system.

Note that we have cherry-picked neither of f80207727aaca3aa nor 
0bcac06f27d75285 in our 4.14.15 build.

Questions:

1. Is there a safe way to break this lock so I can migrate the VMs off of 
   the server?

2. Would it be useful if I run the `stap` script attached in Tetsuo's 
   patch?

Below is the output of sysrq-t *without* Tetsuo's patch. I will apply the 
patch, rebuild, and report back when it happens again.

The first two sections are the ones that are stuck in a "D" state. Note 
that I do not believe that they are deadlocked with each other because of 
their start times being notably different (see below). The rest of the 
trace is repeated below.

I don't know there is.

Thinking from SysRq-t output, I feel that some disk read is stuck.

Since rsyslogd failed to catch portion of SysRq-t output, I can't confirm

But what I was surprised is number of kernel worker threads.
"grep ^kworker/ | sort" matched 314 threads and "grep ^kworker/0:"
matched 244.

Although most of them were idle, and the system had enough free memory
for creating workqueues, is there possibility that waiting for a work
item to complete get stuck due to workqueue availability?
( Was there no "Showing busy workqueues and worker pools:" line?
http://lkml.kernel.org/r/20170502041235.zqmywvj5tiiom3jk@merlins.org had it. )

"Showing busy workqueues and worker pools:" line should be there, for
SysRq-t calls show_workqueue_state().

  static void sysrq_handle_showstate(int key)
  {
  	show_state();
  	show_workqueue_state();
  }

Well, I should not say "One of workqueue threads was waiting"
unless we can confirm that situation did not change over time.

Please take SysRq-t twice with some delay between them

# echo t > /proc/sysrq-trigger
# sleep 30
# echo t > /proc/sysrq-trigger

so that we can "diff" in order to check whether situation
changed over time.

I just tried v4.9.78 and we still get the deadlock. I've backported your 
MemAlloc timing patch and yout timing is included in the output.  Both 
full sysrq traces (30 seconds apart) are available here and I made sure it 
includes both "Showing busy workqueues and worker pools" sections:

==================== 4.14.15 ====================

On the other server running 4.14.15 the stacks look the same as you've 
seen before.  Both full sysrq traces (30 seconds apart) are available here 
and I made sure it includes both "Showing busy workqueues and worker 
pools" sections:

	https://www.linuxglobal.com/static/2018-01-28-hv2-deadlock-v4.14.15

 1125 Sat Jan 27 14:34:40 2018 /usr/sbin/libvirtd          D

I'm not sure if this is relevant, but the load average is wrong on the
4.14.15 machine:
  load average: 1308.46, 1246.69, 1078.29
There is no way those numbers are correct, top shows nothing spinning
and vmstat only shows 1-4 processes in a running or blocked state.

Possibly.  I would not expect a hardware problem since we see this on two 
different systems with different kernel versions.

As linked above, I was able to get the full trace with netconsole.

We have many DRBD volumes and LVM volumes, most of which are dm-thin, so 
that might be why. Also these servers have both scsi-mq and dm-mq enabled.

The missing "Showing busy workqueues and worker pools:" line was a
capture problem on my end, this has been fixed in the new traces linked above.

We are using dm-thin which uses dm-bufio.  The dm-thin pools are working
properly, so I don't think this is the problem---or at least if it is
the problem, it isn't affecting the thin pool.

Thank you. Although the capture is still incomplete, I noticed that
there was a surprising entry.

crm_node was stalling at page fault for 33950 seconds!
That is, crm_node already started stalling at uptime = 45375.

You took SysRq-t after multiple processes (in this case, crm_node and rsync)
got stuck, didn't you? I feel anxious about LIST_POISON1 (dead000000000100) and
LIST_POISON2 (dead000000000200) are showing up at rsync side.

At this point, crm_node already stalled for 209 seconds. Since switches= and
seq= did not change until you took SysRq-t, crm_node kept sleeping.

I guess that /proc/sys/kernel/hung_task_warnings already became 0.
Since the default value of /proc/sys/kernel/hung_task_warnings is 10,
only first 10 warnings are shown. You can set -1 to
/proc/sys/kernel/hung_task_warnings so that all hung_task warnings
are shown.

And since switches= and seq= did not change, crm_node kept sleeping.

libvirtd remained stuck waiting for crm_node.
But something already went wrong more than one day ago.

If I recall correctly, insanely growing load average is a possible sign of
processes getting stuck one by one as one is created (by e.g. crond).

Ideally you could reproduce without DRBD, LVM, bcache etc. , for Marc MERLIN's
report ( http://lkml.kernel.org/r/20170502041235.zqmywvj5tiiom3jk@merlins.org )
was using (at least) bcache. It might be a bug which fails to submit I/O
request.

Some suggestions:


You can enlarge kernel printk() buffer size using log_buf_len= kernel command line
parameter. As your system is large, you could allocate e.g. log_buf_len=67108864 .
Then, you can read kernel buffer using dmesg command (e.g. /usr/bin/dmesg ).
You can add timestamp to printk() messages by doing below command.

----------
# echo Y > /sys/module/printk/parameters/time
----------


Since crm_node starts stalling rather early, you can watch out for kernel
messages and userspace messages which were printed around crm_node started
stalling, for there might be some events (e.g. error recovery) occurring.


I'm not sure but maybe page_owner gives us some clue. (Michal, what do you think?)
You can compile your kernel with CONFIG_PAGE_OWNER=y and boot your kernel with
page_owner=on kernel command line option added. But that alone does not tell on
which "struct page *" processes got stuck. We will need to call dump_page() for
reporting specific "struct page *". One of approaches would be to run a SystemTap
script shown below (in background using -F option) and check how stalling pages
has been allocated. There might be some characteristics with stalling pages.

----------
# stap -DSTP_NO_OVERLOAD=1 -F -g - << "EOF"
global waiting_pages;
probe kernel.function("__lock_page").call { waiting_pages[$__page] = gettimeofday_s(); }
probe kernel.function("__lock_page").return { delete waiting_pages[@entry($__page)]; }
function my_dump_page(page:long) %{
  dump_page((struct page *) STAP_ARG_page, "lock_page() stalling");
%}
probe timer.s(60) {
  now = gettimeofday_s();
  foreach (page in waiting_pages)
    if (now - waiting_pages[page] >= 30)
      my_dump_page(page);
}
EOF
----------

An example allocated by plain write() (though this is without stall period
because I can't reproduce your problem) is shown below.

Michal, what do you think? If no comment, let's try page_owner + SystemTap
and check whether there are some characteristics with stalling pages.

I am sorry, I was on vacation and now catching up. So I will not get to
this anytime soon. Next week hopefully, but I cannot promise anything.

I am not sure page_owner will help us much here. We know this is a shmem
page. Pagelock tracking is quite a PITA so a bisection sounds like a
less PITA even though the reproduction might take quite a lot of time.
Another approach would be to reduce the problem space, e.g. rule out
zram by using a different swap storage.
