Recently (maybe since 4.3.0 or for some models, during 4.4-rc cycle 
before rc5), multiple sparc64 machines have been spontaneously rebooting 
for me during kernel compiles.

First noticed on V240 and E450 (4.3 timeframe).
Recently also on V440, V100, T2000.

Nothing in LOM console history for dmesg, just spontaneous reboot.

All machines have different kernel configs, machine-optimized plus 
random set of debug options and other features.

I am planning to try bisecting this but it will take time. Any other 
good advice for speeding up the pinpointing?

Well, T2000 is probably a false alarm this time, sorry. The others are 
still problematic.

I was able to build on a 4.4.0-rc3+ on my V440, using "make -j 80"
What were your build params?

make -j4 only. Underlying kernel config might also be relevant. And it 
did not happen every kernel compile - but often enough. Once even 2 
times per compilation.

So far I have made sure that 4.2.0 works fine on V240 overnight with the 
following command to find any other errors too.
while true; do make clean; make -j2 || break; done

Testing 4.3 on V240 currently.

let me restart a loop with your .config on my v440 and let this run
overnight, to see if I can reproduce your case.

Hmm. I've rebooted my v440 with a kernel built with your .config,
I've been able to do the above make loop for several hours now. 

perhaps it is some service/module that you have enabled/loaded
that I dont? Would you like to compare output of lsmod and/or 
chkconfig and/or service--status-all? (let me know which one).

Other thing is, there is nothing in the console/logs to 
give a hint why it rebooted?

It could also be influenced by either the amount of memory he has
installed, or what userland he is using.

For now it seems 4.3.0-00063-gea2d67b and 4.3.0-08824-g7c623ca also 
survive for many hours. That is strange - I think I saw it earlier on 
v240 where I am currently testing (I have seen it multiple times on 
v240, only once or twice on v440).

Now I have also ran 4.4-rc8 on v440 for some hours and it seem to 
survive.

So I do not know how to reproduce the reboot at will :(

Nothing in ALOM console log history or in syslog.

v240 has 6G RAM, v440 has 8G.

Userland is Debian unstable, as it was as of July 25, 2015. gcc 4.9.3-2, 
binutils 2.25-10.

My usage pattern on all the machines was powering up the machine, doing
git pull && make -j4 && echo OK
where -j number corresponds to number of CPUs in the system. Maybe git 
pull created some memory pressure before?

ps shows I have running
init udevd dhclient uuidd rsyslogd atd cron irqbalance sshd exim4 ntpd 
getty + sshd,bash for my login session.

v440 also has /usr/bin/daemon /etc/init.d/mpt-statusd check_mpt

init is sysvinit on both machines.

irqbalance and ntpd are the only slightly suspicious ones for my eye, or 
i2c modules but these are only on v240.

maybe it's the gcc/binutils? I'm using something older:

# gcc --version
gcc (Debian 4.6.3-14) 4.6.3
Copyright (C) 2011 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

My binutils is 2.22-8+deb7u2

the other difference is that (due to firewall/proxy headaches) I 
git-pull on a different machine and then rsync over that tree to
the v440. 

I did not see anything significantly different about the ps/interrupts
etc. I do not have irqbalance or ntpd on the v440, though.

I have been running V440 and V240 since last mail and I have not been 
able to reproduce the reboot in any way at will.

V440 is running 4.4.0-rc8-00005-gee9a7d2-dirty where dirty means ali1533 
quirk patch.

V240 has been running 4.4.0-rc8-00005-gee9a7d2.

When I hit it next time, I will take note and try to find the 
specific conditions.

It's getting more strange. I ran 4.4-rc8-00005 for 2-3 weeks nonstop, 
doing git clone and make -j4 in a loop, on both V240 and V440. Worked 
100% stable.

Then I git git pull from kernel.org, tried to compile 4.5-rc1 (or was it 
rc2 already), on the same running 4.4.0-rc8-00005 and it rebooted, on 
both V240 and V440.

I also saw a spontaneous reboot on E450 with 4.4.0-rc5-00008. Did not 
try continuous building on E450.

I'm quite stumped in trying to reproduce that...

sorry for not getting back sooner - was on the road, and will be
mostly offline again next week. But the symptoms sound like there 
might be a memory and/or compiler issue. I'm not sure how to check this
theory out.. maybe someone else with more expertise in this space
can check?

If not, I can come back and try this out in a week- will take
some extra config/pkg-installation in my test machine to get around
firewalls etc and run git directly from the sunfire.

Hmm, probability-wise that is not very likely that at least 4 different 
machines (V240, V440, E450, V100) grow a hardware error at 4.3 timeframe 
and start rebooting spontaneously?

Maybe something with our memory detection / bootmeme / memory ranges has 
changed?

Il will try more to find a way to reproduce the problem. Maybe putting 
aside an old git tree state (how do I get one?), then at each boot copy 
it and pull it and then compile.

shouldnt "git checkout" to an older commit id achieve this?

Hmm. My experience was a little different than yours but maybe we
are seeing the same thing. 

I get a panic that matches the description in d188ba86dd07a ("xfrm:
add rcu protection to sk->sk_policy[]") but the panic remains
even after applying that patch, so maybe there is still some
race-window that was missed by the patch (or I'm missing some additional
patches?)

To reproduce the panic on my v440 (sparc sunfire) I fixed up my transparent
proxy env, and do a 'git pull' on the test machine (running 4.4.0-rc3+).
The reboot on panic was quite noisy on the (serial line to) console, though I
didnt find anything recorded in /var/log/*, and, with
kernel.panic = kernel.panic_on_oops = 1, the ssh session terminates quietly.

here's what I pulled out from the console noise:

I figured out what's the root-cause of my panics.

In my case, for the stack shown in 
 http://marc.info/?l=linux-sparc&m\x145610295109214&w=2
(which also has all the details about the issue),

tcp_make_synack has been called with attach_req set to true
so it sets up the skb->sk via:

        if (attach_req) {
                skb_set_owner_w(skb, req_to_sk(req));
        } else { /* .. */

Now, req is a struct inet_request_sock, and we are casting this
as a struct sock, to later get the ->sk_policy[1] in the xfrm
code. Consider the sizes of these structures between 32 and 64 bits:

  sizeof             32-bit        64-bit
-------------------------------------------
request_sock          256           312
inet_request_sock     272           328
sock                  688          1216

And offsetof sk_policy[1] is 256 on the 32-bit v440, whereas
it is 520 on my 64-bit T5. 

Thus on the v440, the sk_policy[1] is pointing at somewhere
in the middle of stuff set up by tcp_openreq_init() (the ireq
flags initialization).

Even on the 64-bit arch, trying to do req_to_sk(req) and accessing
fields beyond the sock_common, e.g., between offset 312 and 328 
may not give you the fields you are looking for? 

so how is this supposed to work? (Evidently it worked for Meelis
before, but I dont know if that was before or after  commit
9e17f8a475).

Sorry, I do not understand - what is 32-bit on V440? The kernel should 
be 64-bit since it's sun4u.

It might be related to my problem, yes (I have different kernel configs 
on different machines and the XFRM settings are varying at least). 

However, I have not succeeded in reproducing the problem at will - git 
checkout of another release + subsequent compile still does not trigger 
it. But if it is the same problem, it seems to go int triple fault or 
something similar for me to cause it reboot with no trace in the 
console.

Maybe you're seeing something else then.

Just got something - not on the console but a livelock with 
4.5.0-rc5-dirty. However, this seems to be mm-related?

This one has git checkout of v4.3 + git checkout master running, ps 
hangs when reaching this process. Simple pstree works, pstree -plah 
hangs, pstree -cp whows 3 gits running, catting /proc/PID/cmdline of one 
of them is hanging again. wchan is vm_munmap, status shows state D as 
expected.

Just got something - not on the console but a livelock with 
4.5.0-rc5-dirty. However, this seems to be mm-related?

This one has git checkout of v4.3 + git checkout master running, ps 
hangs when reaching this process. Simple pstree works, pstree -plah 
hangs, pstree -cp whows 3 gits running, catting /proc/PID/cmdline of one 
of them is hanging again. wchan is vm_munmap, status shows state D as 
expected.

hang on; The sizeof (and offsetof) values I listed were obtained either
from /usr/bin/crash (on the T5) or from simple printk's of the structures
in the case of the v440. And they *are* different, and the numbers
match the values dumped on the console on pnaic. So isnt there actually
a problem here?

There certianly seems to be a problem - that's how you ended up looking 
under that rock.

Maybe the offsets are different because of different kernel config?

Since there are no config-dependent difference in the struct, maybe it's 
a compiler version difference for padding/optimization instead?

possibly. The v440 is using  a Debian 4.6.3-14 gcc, while the
T5 is using "4.4.7 20120313 (Red Hat 4.4.7-4)"

But my question from the email remains. Unless I am missing
something subtle in the code, a  struct request_sock and a 
struct sock only have the sock_common part in common. So casting
a request_sock as a struct sock may have issues?

Of course it can have issues and contextually we have to be careful
about what the code can assume about that casted 'sk' object.

Your report looks legit and I was hoping Eric would chime in here with
an analysis.

Eric, we can't access sk->sk_policy[] on a request sock.  I guess we'll
have to use the sk->sk_policy[] of the parent?

Changing the layout of a structure would break ABI, so unlikely.

I've never used crash, so I have no idea where it gets it's
information from nor how it interprets it.

fwiw, I applied the exact same printk to the T5, namely,

                printk(KERN_INFO "sizeof sock %ld \n"
                        "sizeof request_sock %ld\n"
                        "sizeof inet_request_sock %ld\n"
                        "offsetof sk_policy 1 %ld\n",
                        sizeof (struct sock), sizeof (struct request_sock),
                        sizeof (struct inet_request_sock),
                        offsetof(struct sock, sk_policy[1]));

and got this:

   sizeof sock 1216 
   sizeof request_sock 312
   sizeof inet_request_sock 328
   offsetof sk_policy 1 520

So it's good to know that crash does not lie.

But then it's odd that the struct sizes (esp of things like 
request_sock, which are not config dependant) are not the same.

Every structure that has a lock, or something that contains a lock
(such as a timer or whatever), has a layout which is config dependant.
And I'm pretty sure request_sock falls into this category.

Any number of debug and lock verification config options can control
the layout of spinlock and other core datastructures.
