Xen 4.8 + Linux 4.9 + Credit2 = can't bootup

[Konrad Rzeszutek Wilk]

Hey,

I was trying to bootup on an 30 CPU machine (15 core, SMT).

It works just fine with credit1 (see further down the log)
but if I try credit2 it ends up hanging during bootup. 

I am a going to naively assume it is due to how the vCPUs are
exposed (Where they match the physical CPUs under credit1),
but under credit2 they are different.

The dom0_max_vcpus does not seem to have any affect. When I remove it
things are still being problematic.

Help!?

Please see attached serial log.

This matches the symptoms seen by XenServer when trying to stress 32vcpu
guests under Credit2.  Malcolm did find (based on interpreted iperf
throughput graphs) that Credit2 did seem to preferentially schedule the
lower-number vcpus, rather than scheduling them evenly.

The iperf graphs showed this as having a diminishing graph of vcpu id vs
total traffic passed (which was a straight line under credit1), but
Linux deciding a soft lockup is also very plausible is there is
asynchronous scheduling.

To be fair (and just for the records, since the cause seems actually to
be something else), this was with an old version (at least two Xen
releases ago, IIRC, certainly not 4.8) and known to be buggy version of
Credit2.

We have other tests and benchmarks, done on equally big machines which
proves the scheduler is 100% functional.

Dario

Yes, I have done extensive stress tests on XenSever(IIRC Xen - 4.7) with 
Credit2 on 32 or more VCPU guests. Didn't see any hangups.

Malcolm, did find hangup and crash issues with 32VCPU guests, but the 
issue was highlighted and fixed. So, during my testing I specifically 
foucussed on this scenario and found no problem.

It seems now that I took dom0_max_vcpus out of the picture I can
reproduce this with credit1 scheduler. So it looks like an Linux issue.

Boris, any ideas? This is 4.9.

I think 4.9 is broken. There were changes in topology initialization 
that broke Xen in early 4.9 RCs. tglx posted a patch that resolved this 
issue (he was actually addressing something else and fixing dom0 crash 
was a side effect). I thought it would make it to 4.9 but apparently it 
didn't: I just tried 4.9 with default Xen scheduler and it crashed. Not 
with the error that you are seeing though:

Latest 4.10-rc2 boots both credit1 and credit2. So you can either try 
that or apply 9d85eb9119f4eeeb48e87adfcd71f752655700e9, which I think is 
the missing patch.

Maybe it's me misremembering/saying stupid things, but I recall that at
some point we were testing some of the recent and in development Linux
branches in OSSTest.

I don't think we do that any longer, and that may be part of the reason
why we missed this one?

Ian, Wei, thoughts?

I believe you needed to be on a multi-socket system to catch this bug.
That's why, for example, my tests missed it --- the boxes that I use are
all single-node.

Yeah, while I do test on NUMA, but I do mostly Xen development so I
test the latest Xen but (most of the time) with whatever distro kernel
is easier to use (although, usually fairly recent ones, like 4.8).

Anyway, we should have some multi-socket boxes on OSSTest, AFAICR.

I think we do but I haven't got a systematic way of answering that
question other than by manual eyeballing of the spec sheets.

IF there were something easy to look for in the dmesg output (say) I
could probably grep historical logs.

[root@ovs104 ~]# xl dmesg | grep Scrubbing
(XEN) Scrubbing Free RAM on 2 nodes using 16 CPUs
[root@ovs104 ~]#

or

[root@ovs104 ~]# xl info | grep nr_nodes
nr_nodes               : 2
[root@ovs104 ~]#

may be useful.

BTW, when I said that the problem that this thread was started with 
required multi-socket system I should have also said that dom0 needs to 
span nodes (or so I think).

Which will happen in OSSTest in most cases, as we don't usually use
dom0_max_vcpus, AFAICR.

But I think the point here is really what Ian was asking. I.e., leaving
aside the specific characteristic of this very issue, do you (and
Juergen and Konrad) think it would be useful to have OSSTest smoke test
upstream-ish kernel again?

I think it is you, Xen-Linux people, that may find it helpful, as it
may save you some local testing, etc. But this is only true if you
think it could fit in your workflow to check its output and deal with
it, which is something only you can tell. :-)

If the answer is no, then nevermind, and sorry for the noise. :-D

Dario

I can give it a try although I have practically no experience with
OSSTest. Is there a way to subscribe to notifications for those tests?

osstest's reports are posted to xen-devel.  To give you an example of
what they look like, I have pasted below the top of the report from
last test report of linux-linus (including interesting mail headers).

If you find the mail filtering of xen-devel awkward, I can arrange to
send these to a specific list, or something.

As I say the Linux kernel ones that we are discussing are currently
disabled, so the mail below is from last April and all of the logs it
refers to will have expired.

If someone is volunteering to look at the output I can re-enable
them.  Previously we were testing:

  linux-linus
    git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

  linux-next
    git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git

  linux-mingo-tip-master
    git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git

(In each case that list contains the osstest `branch' name which
occurs in the Subject line etc., and the URL.  In each of the above
cases we test `master'.)

Ian.

Hopefully I should be able to filter on "X-Osstest-Failures includes
"linux-linus:".

I think linux-linus would be the most interesting to test. Can you
enable just that one? I'll see if I can parse results.

The first report from the restarted tests is below:

So
  1. it doesn't boot on some (but not all) hosts
  2. it doesn't build on armhf (32-bit ARM)

Shouldn't this be:

git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

(instead of linux-2.6.git?)

We used to, but no-one fixed any of the bugs it discovered so I turned
that off in April.

Possibly now that osstest is performing better I should turn these on
again.  Do we have anyone who will take care of chasing down the bugs
and getting them fixed upstream ?

Date: Fri, 22 Apr 2016 15:54:43 +0100

It appears that no-one is looking at the output.  These have not had a
push to the tested output branch for at least 250 days (742 days in
the case of linux-linus!) and the reports don't seem to be generating
any bugfixing activity.

There is a plan to do some Xen testing in Zero-day but even if that
doesn't lead to anything we would still be just where we are now.

So drop these to save our test bandwith for more useful work.

Assuming that the last session in serial-nocera1.log is the one that
failed, I wonder whether these is something with the mpt2sas --- it's
the last thing that's reported before debug-keys are activated:

ARM build seems to be caused by some sort of a timeout. The script
allows about 2.5 hours for the build to complete and it looks like it is
close to finishing it. Hard to say why it takes that long but I see no
build errors --- IIUIC the build is aborted due to the timeout.

I have had other reports of problems with mptsas.  For example,
see this bug:  http://bugs.debian.org/850425

The osstest bisector worked on this:

Unfortunately it has fingered a merge commit.

This means that the bug is in commits which diverged before the last
pass of this test.

(Did your filters get you a copy of the bisection email?)

That particular bug appears to have swiotlb "overflow" in its signature,
which osstest log doesn't have.

No, I haven't set a filter for the bisector but I did see this message
and didn't find bisection results particularly useful. bcc981e9ed84 is
from about a year ago, which, I think, is when you stopped running this
test. And so the question might be whether "Bug not present" is really true?

It means that this precise combination of software was tested and
passed, recently, on the same hosts, several times.

See
  http://logs.test-lab.xenproject.org/osstest/results/bisect/linux-linus/test-amd64-amd64-xl-qemut-win7-amd64.xen-boot.html
where you can see the flight numbers.  (They are sequential.)

So yes it is really true.

Here is a typical scenario that leads to the mptsas error:
...
Jan 19 13:09:39.545726 [   10.241093]  sda: sda1 sda2 < sda5 >
Jan 19 13:09:39.609596 [   10.314016] sd 4:0:0:0: [sda] Attached SCSI disk
Jan 19 13:09:39.681544 [   19.883573] random: crng init done
Jan 19 13:09:49.249674 [   40.938069] sd 4:0:0:0: attempting task abort!
scmd(ffff880016e06600)

command pass through(12)/Blank a1 08 2e 00 01 00 00 00 00 ec 00 00
...

There is difference of about 30 seconds between the disk attachment and
abort sequence initiation. Which also happens to be default scsi disk
timeout. For example:

root@haswell> for f in /sys/block/sd?/device/timeout; do echo -n $f ":
"; cat $f; done
/sys/block/sda/device/timeout : 30
/sys/block/sdb/device/timeout : 30
root@haswell>

So it looks like the device may have timed out for some reason.

On the off-chance that he might know right away what this is I asked
SCSI maintainer (Martin Petersen) and he thought that this might be the fix:

http://git.kernel.org/cgit/linux/kernel/git/mkp/scsi.git/commit/?h=4.10/scsi-fixes&id=ffb58456589443ca572221fabbdef3db8483a779

Pull request was sent to Linus yesterday so it should be in the mainline
shortly.

2.5 hours!  How long should it take do you think ?

I mean, I can increase the timeout, but this already seems quite
unreasonable.

I don't have much experience with ARM HW but on my x86_64 desktop it's
under 5 minutes. Of course, we may have different config files but still...

And those 2.5 hours is almost all for the actual build --- from what I
see git clones are done pretty quickly.

So this appears to be a pretty slow, 2-core box:

[ 0.049778] SMP: Total of 2 processors activated (96.00 BogoMIPS).

Julien --- how does 2.5 hours for kernel build sound to you? (make -j4
all modules)

For comparison, my (old-ish) phone is 4 x 26 BogoMIPS. So it's
theoretically faster than this server.

The ARM32 platforms we have in the colo are not server but development 
board :). Some of them are based on early revision of cores and can be 
really really really really ... slow.

I would not be surprised that it takes 2.5 hours for a make allmodules 
on both the Cubietruck and Arndale.

I have looked at the Linux-3.18 test flights, I know that this thread is 
linux-linus but not other flight log can be found. So surprisingly the 
time betwen the last two flights of Linus 3.18 has doubled (see [1] and 
[2]).

The major difference is a Cubietruck is used on the latest version and a 
Arndale on the previous one. I am be surprised that the Cubietruck is 
slower than the Arndale. Oh well..

The interesting bit is the build time on the Cubietruck is very close to 
the threshold. It is likely that the latest kernel have more modules to 
build which increased the time to build.

So I can see 2 solutions:
	1) Increase the timeout
	2) Only build the kernel on the Arndales. Though they are known to be 
unreliable in the colo :/

Any opinions?

Cheers,

I'd vote for (1). Alternatively we could cross-compile on an x86 box.

I can do either of these.  (I have just pushed to pretest a series
which will make it easier to increase the timeout for these specific
hosts.)

I'm inclined to increasing the timeout, although this slowness does
mean that our tests may be blocked more than we would like.

Ian.

I have set the host property which I think will cause the timeout to
be increased.  This should take effect for the next run of
linux-linus.

Thanks.

And it looks like x86 tests passed this morning so presumably the SCSI
patch indeed fixed the problems.
