Weirdness with suspending jobs in 2.6.9-rc3

Weirdness with suspending jobs in 2.6.9-rc3

Hello,

It seems that make (possibly among other things) has been affected by
some change in 2.6.9-rcX that prevents it from resuming some jobs.

I created this Makefile as a testcase:

all:
	sleep 5
	echo Hi
	sleep 5

The result:

darjeeling:~{0}% make
sleep 5

zsh: suspended  make
darjeeling:~{1}% bg
[1]  + continued  make
make: *** wait: No child processes.  Stop.
make: *** Waiting for unfinished jobs....
darjeeling:~{1}% echo Hi
Hi
make: *** Waiting for unfinished jobs....
sleep 5
make: *** Waiting for unfinished jobs....

[1]  + exit 2     make

This happens with bash also. I'm pretty sure it didn't use to happen
with older kernels. Any ideas?

Thanks

I'm also observing this problem.

It doesn't depend on which version I'm compiling, it depends on which 
kernel I'm actually running.

(2.6.9-rc1 is OK, 2.6.8-rc3-mm3 is not OK.)

Yeah, that's really what I meant the first time.

Good to hear. I might switch back.

Neither I not Roland could reproduce this.

What about current -linus?

Is there any way in which you can do a bit of bisecting, identify the
offending patch?

Also affected.

It happened between 2.6.9-rc1-bk7 and 2.6.9-rc1-bk8. Roland's waitid patch
most likely breaks it but I'm too tired right now to specifically revert
that. If that's enough for you, well, fix it.. If not I'll try and narrow
it down tomorrow.

What kinds of machines are you people testing on? Perhaps it only happens
on UP. Andrew probably has some 12-way box to compile new -mm kernels
with which he's using..

Off-list?

Maybe this is useful too?

Started make on that test Makefile, and

% strace -p 31810
Process 31810 attached - interrupt to quit
wait4(-1073750280, NULL, 0, NULL)       = -1 ECHILD (No child processes)

it then immediately proceeded to give the old 'no child processes.
Stop.' thing.

Strangely, the bug is experienced only sporadically when using make -j2
on a kbuild. Maybe that's just a coincidence.

That is a clearly bogus argument.  (In fact it looks like a stack address,
a common thing to be found in uninitialized variables.)  Unless you have
some reason to suspect that this is not the argument actually passed by
make, then you should look at make and see why it passed the bogus
argument.  So far, I still don't see a direct suggestion of a kernel bug
here.  



Thanks,

All I know is that this doesn't happen in kernels where the waitid patch
was not applied. It has *NEVER* happened until now.

Possibly it was strace catching the wrong end of whatever make was doing
when it started ptracing it.

Could it be glibc's problem.

That's obviously suggestive, but it's real hard to know whether it's just a
coincidental perturbation of the timing or who-knows-what triggering a bug
elsewhere, or a new kernel bug, without more concrete information about
what goes wrong.

If you can work more on providing a way for people like me and Andrew to
get this to reproduce for us, then we will be able to make quick progress
from there.  Right now, all we can really do is make suggestions to you for
how to proceed with debugging and you'll have to be the one to dig up more.

I don't know any sane scenario that would result in the value you showed in
that wait4 call from strace.  We really need to learn more about how that
happens.  

> Could it be glibc's problem.

This seems unlikely unless you changed your glibc very recently, but
anything is possible.  I think you should continue to work with tools like
strace and/or gdb to figure out where this bogus value comes from.  

If you have trouble catching make losing in gdb, you could also do
something funky like hack your kernel to do something like:

	if (pid != -1 && (pid & 0xff000000)) 
		force_sig_specific(SIGSEGV, current);

in do_waitid.  This should cause make to dump core at the bogus system
call, and then you could examine the core file with gdb to learn more about
how it wound up passing that bogus value.

Hi. I see it too:

wait4(-1073750328, NULL, 0, NULL)       = -1 ECHILD (No child processes)

But the whole problem goes away if I switch CONFIG_REGPARM off. To reproduce
it needs CONFIG_REGPARM=y.

Hope this helps.

Interesting.

What command are you actually running to demonstrate this?  Full details,
please.

First 'make' while the Makefile is this

all:
	sleep 40
	echo Hi
	sleep 5

and then in a different window 'ps ux' and then 'strace -p PID'. If
CONFIG_REGPARM if off then the strace starts:

Process 324 attached - interrupt to quit
wait4(-1, [{WIFEXITED(s) && WEXITSTATUS(s) == 0}], 0, NULL) = 325
--- SIGCHLD (Child exited) @ 0 (0) ---
sigreturn()                             = ? (mask now [])
write(1, "echo Hi\n", 8)                = 8

if CONFIG_REGPARM=Y then it starts:

Process 14226 attached - interrupt to quit
wait4(-1073750328, NULL, 0, NULL)       = -1 ECHILD (No child processes)
write(2, "make: *** ", 10)              = 10
write(2, "wait: No child processes", 24) = 24
write(2, ".  Stop.\n", 9)               = 9
write(2, "make: ", 6)                   = 6

eww, OK, happens here too.

And the problem also exists on a kernel compiled with gcc 3.3.4.

Are you able to strace the same workload on an earlier kernel and work out
whether `make' is still passing in a funny PID and if so, what the kernel's
response is?

The problem seems to be surprisingly old.

In -mm, I was able to reproduce it in 2.6.8.1-mm1 (several older -mm 
kernels don't boot on my machine due to the floppy issues already 
discussed).

In Linus' tree, 2.6.9-rc1 is OK, but both 2.6.9-rc2 and 2.6.9-rc4 show 
this problem.

What else might matter? Userspace? I'm using a Debian unstable.

I was thinking that maybe our libc not supporting the 'waitid' syscall
might be the problem? (Yes, debian unstable here too.)

Not sure, but every indication points to Roland's waitid patch being the
culprit.

 I got bit by this error several times using slrn (news reader in s-lang).
If I press ^Z, slrn suspneds but spews error on 'fg'. Something about
IO error. It happened only om -mm kernels.
 I've saved strace output on -linus (where it worked), but beeing unable
to strace it on -mm [1] I deleted all logs and learned not to press ^Z.

[1] strace hung my system on -mm few times.
